Pasos Hacia La Salud: a randomized controlled trial of an internet-delivered physical activity intervention for Latinas

Role of Technology in Promoting Heart Healthy Behavior Change to Increase Equity in Optimal Cardiovascular Health: A Scientific Statement From the American Heart Association

Populations most affected by cardiovascular health disparities, including underrepresented populations with lower socioeconomic status, people with disabilities, and those living in underserved rural communities, are disproportionately exposed to adverse social determinants of health. Specifically, economic instability and suboptimal living conditions within the neighborhood and built environment directly determine access to resources and opportunities for healthful behaviors. In this scientific statement, we examined the technology-enabled interventions that address cardiovascular health behaviors from adolescence to adulthood in populations most affected by health disparities. We used a broad definition of technology, including wearables, applications, and telehealth, for behavior tracking. Aligning with Life's Essential 8, we focused on interventions targeting behavior change related to physical activity, sedentary time, dietary intake, tobacco cessation, and sleep health to improve cardiovascular health. The digital determinants of health are important adjuncts to the social determinants and operate at the individual, interpersonal, community, and societal levels. The digital determinants of health include the impact of digital technologies (eg, wearables, telemedicine) across health outcomes. Evidence of effective interventions using technology to improve cardiovascular health through positive behavior change is critical for preventing cardiovascular disease events. Stronger evidence is needed to inform and implement effective approaches that are scalable and cost-effective across communities and health care institutions to advance digital equity in cardiovascular health. Dissemination of digital solutions to improve cardiovascular health in communities or across health care systems must ensure effective, feasible, available, and affordable solutions for populations most in need.

Randomized controlled trial of a multiple technology-based physical activity intervention for Latina adolescents: Recruitment strategies and baseline data from the Chicas Fuertes trial

BACKGROUND

Latina adolescents report low levels of physical activity (PA) and high lifetime risk of lifestyle-related diseases. They also have high rates of using technology, suggesting interventions delivered through mobile devices may be effective for this population. The current paper describes recruitment methods and baseline study characteristics for Chicas Fuertes, a fully powered randomized trial of a mobile technology PA intervention.

METHODS

Underactive Latina adolescents (aged 13-18) were recruited using social media and presentations at local schools and community organizations in San Diego, California. Participants were randomly assigned 1:1 to either the intervention (Fitbit, tailored texting, social media, and website) or control group. Baseline measures included demographics, psychosocial variables, and PA measured by the 7-Day Physical Activity Recall (PAR), ActiGraph GT3X+ accelerometers, and Fitbits. Baseline data were collected from 2020 to 2023.

RESULTS

Social media yielded the most contacts (465), but had the lowest chance of enrollment (14 %, vs. 52 % from school presentations). Participants (N = 160) were mostly second generation (68.8 %), and low income (61.8 %), but technology access was high (>99 %). Median self-reported moderate-to-vigorous PA (MVPA) using the 7-Day PAR was 120 min/week (range 0-720), and median daily steps were 5222 (IQR 359). Median MVPA measured by ActiGraphs, however, was 0 min per week. There was no correlation between the 7-day PAR and ActiGraphs (ρ=.13,p=.12). However, ActiGraph MVPA was correlated with total steps recorded by the Fitbit (ρ=.38,p<.001).

CONCLUSIONS

Both remote and in-person approaches were successful in recruiting a sample that was underactive and low income, but had high technology use.

A systematic review on eHealth technology personalization approaches

Despite the widespread use of personalization of eHealth technologies, there is a lack of comprehensive understanding regarding its application. This systematic review aims to bridge this gap by identifying and clustering different personalization approaches based on the type of variables used for user segmentation and the adaptations to the eHealth technology and examining the role of computational methods in the literature. From the 412 included reports, we identified 13 clusters of personalization approaches, such as behavior + channeling and environment + recommendations. Within these clusters, 10 computational methods were utilized to match segments with technology adaptations, such as classification-based methods and reinforcement learning. Several gaps were identified in the literature, such as the limited exploration of technology-related variables, the limited focus on user interaction reminders, and a frequent reliance on a single type of variable for personalization. Future research should explore leveraging technology-specific features to attain individualistic segmentation approaches.

Changes in the Perceptions of the Neighborhood Environment and Physical Activity Patterns Among Mexican Americans on the Texas-Mexico Border

INTRODUCTION

Little research on the association of neighborhood environment with physical activity in resource-poor communities has been done. This study assessed changes in perceptions of the neighborhood environment and the association between those perceptions and physical activity in Mexican Americans on the Texas-Mexico border in an area where there would be community efforts to enhance pedestrian and cycling infrastructure and programming.

METHODS

We analyzed data from a population-based cohort of Mexican American individuals on the Texas-Mexico border. From 2008 to 2018, interviewer-administered questionnaires were used to collect perceptions of neighborhood environment and physical activity at baseline, 5- and 10-year follow-ups, and at other ancillary study visits, with an average of 3 data points per participant. We conducted multivariable longitudinal logistic regression analyses to assess if the changes in odds of positive perceptions of the neighborhood environment over the study years differed by physical activity patterns.

RESULTS

The sample (n = 1036) was mostly female (71%), born in Mexico (70%), and had no health insurance (69%). We saw improvements in the perceptions of several neighborhood environment attributes from 2008 to 2018, though we saw different longitudinal trajectories in these perceptions based on an individual's longitudinal physical activity patterns. By 2014-2018, we saw significantly higher positive perceptions of the neighborhood environment for those who consistently met physical activity guidelines compared with those who did not (adjusted rate ratio = 1.12, P = .049).

DISCUSSION

We found that perceptions of many neighborhood environment attributes improved between 2008 and 2018, and that overall positive perceptions were associated with consistently meeting physical activity guidelines over time.

Pasos Hacia La Salud II: A Superiority RCT Utilizing Technology to Promote Physical Activity in Latinas

INTRODUCTION

Latinas face an increased risk for chronic diseases associated with insufficient physical activity (PA). The researchers previously showed that a website-based intervention could increase PA among insufficiently active Latinas, yet rates of meeting national PA guidelines were low. The original intervention was enhanced by adding additional features, content, and points of contact, including via text messaging. This study tests the efficacy of the enhanced intervention compared with the original, aimed at maximizing and sustaining PA gains across 24 months. It also examines if increases in PA differed by baseline PA.

STUDY DESIGN

The researchers conducted a superiority randomized controlled trial (data collected 2018-2022, analyzed 2023).

SETTING/PARTICIPANTS

Participants were 195 Spanish-speaking Latinas ages 18-65 in the Providence, RI area.

INTERVENTION

The original intervention is an empirically supported Spanish-language, individually-tailored, website-delivered PA intervention. The enhanced intervention includes text messaging and additional data-driven content and interactive features.

MAIN OUTCOME MEASURES

Total weekly minutes of moderate to vigorous PA (MVPA) was measured via accelerometry and self-report at 6, 12, 18, and 24 months.

RESULTS

Participants in both groups increased their MVPA over 24 months. There were no significant between-group differences at 6 or 12 months; at 18 months the enhanced intervention group had higher levels of self-reported (mean (sd): 90.35 (43.55) vs 70.18 [9.99]) and accelerometer-measured (66.21 [18.26] vs 60.27 [16.00]) MVPA compared to the original intervention group. They also had higher levels of self-reported (111.17 [23.35] vs 81.44 [1.82]) and accelerometer-measured (63.76 [15.12] vs 54.86 [14.59]) MVPA at 24 months. Baseline PA moderated the intervention effect.

CONCLUSIONS

This study demonstrates the potential to enhance the efficacy of website-based PA interventions by utilizing text messaging, and adding more interactive features, content, and phone support. These enhancements may be particularly beneficial in supporting long-term PA maintenance.

Six-Month Outcomes of a Theory- and Technology-Enhanced Physical Activity Intervention for Latina Women (Pasos Hacia La Salud II): Randomized Controlled Trial

BACKGROUND

More than half (55%) of Latina women do not meet aerobic physical activity (PA) guidelines, and frequently cite time, childcare, and transportation as barriers to PA. In addition to linguistic adaptations for this population, successful PA interventions for Latina women addressed these barriers through remote intervention delivery approaches (eg, mail, phone, or web delivery).

OBJECTIVE

We aimed to evaluate 6-month outcomes of a randomized trial comparing a Spanish-language, individually tailored, web-delivered PA intervention (original) to an enhanced version with text messages and additional features (enhanced). Further, we evaluated if increases in PA at 6 months were moderated by baseline activity status.

METHODS

In total, 195 Latina women aged 18-65 years participated in a trial comparing the efficacy of the enhanced versus original interventions at initiating PA behavior change. We examined minutes per week of accelerometer-measured PA in the enhanced versus original arms, and the proportion of each arm meeting aerobic PA guidelines (150 min/wk at 6 mo). For moderator analyses, participants were classified as inactive (0 min/wk) or low active (1-90 min/wk) at baseline, measured via the 7 Day Physical Activity Recall interview.

RESULTS

PA increased from 19.7 (SD 47.9) minutes per week at baseline to 46.9 (SD 66.2) minutes per week at 6 months in the enhanced arm versus 20.6 (SD 42.7) minutes per week to 42.9 (SD 78.2) minutes per week in the original arm (P=.78). Overall, 30% (31/103) of the enhanced group met aerobic PA guidelines at 6 months, compared to 21% (19/92) of the original group (odds ratio [OR] 1.75, 95% CI 0.87-3.55). Baseline PA (inactive vs low active) moderated treatment effects on PA. For inactive participants, there were no group differences at 6 months (b=7.1; SE 22.8; P=.75), while low-active participants increased more in enhanced than original (b=72.5; SE 27.9; P=.01). For low-active participants, 45% (46/103) of the enhanced group met PA guidelines at 6 months, versus 20% (18/92) of the original arm (OR 3.29, 95% CI 1.05-11.31). For inactive participants, there were no group differences (25/103, 24% vs n=19/92, 21% for enhanced vs original, respectively; OR 1.28, 95% CI 0.54-3.06).

CONCLUSIONS

Intervention effects were conditional on baseline PA. For low-active Latina women, the enhanced intervention was more effective at increasing PA. Additional tailored intervention enhancements may be necessary to increase PA for inactive Latina women.

Promotion of Muscle-Strengthening Activity Among Latina and Black/African American Women: A Review of Literature

Latina and Black/African American (AA) women report disproportionately low levels of muscle-strengthening activities (MSA) and high rates of related chronic health conditions. Despite the health benefits of MSA, physical activity intervention research in these populations has focused mostly on increasing aerobic physical activity. The purpose of this review was to describe the current state of scientific literature on MSA interventions among Latina and Black/AA women. Two electronic databases, CINAHL and PubMed, were searched for studies published during the past 10 years. Studies were included in this review if they reported promotion of MSA, included at least 50% Latina and/or Black/AA women in their samples, and used an interventional design. Search procedures identified 8 unique interventions targeting MSA in Latina (n = 3) and Black/AA women (n = 5). Results revealed there is limited published research on MSA promotion among Latina and Black/AA women, especially on theory-based interventions that address psychosocial and behavioral influences of MSA, as well as assessment of MSA outcomes in these populations. This review highlights a critical need for research on culturally tailored behavioral interventions to reduce the low MSA in Latina and Black/AA women and provides future research directions on this topic.

Barriers and Facilitators to Muscle-Strengthening Activity Among Latinas in the U.S.: Results From Formative Research Assessments

BACKGROUND

Latinas are disproportionately affected by low physical activity (PA) levels and related health conditions (e.g., diabetes, obesity). Few Latinas in the U.S. (17%) meet the National PA Guidelines for both aerobic PA and muscle-strengthening activity (MSA), yet, research to date in this population has focused almost exclusively on aerobic PA. Performing regular MSA is linked with numerous health improvements and reduced mortality; thus, may be key to addressing health disparities in this community. This study examined perspectives on engaging in MSA among Latinas enrolled in two aerobic PA RCTs.

METHODS

Brief quantitative surveys were conducted to assess interest in MSA among Latinas (N = 81), along with 19 follow-up in-depth semi-structured interviews on knowledge, barriers, and facilitators for engaging in regular MSA. Interview transcripts were analyzed by two independent bilingual researchers using a directed content analysis approach.

RESULTS

Eighty-one Latinas (18-65 years) completed the survey. Most (91%) expressed interest in learning more about MSA and 60% reported not knowing how to do MSA as a substantial MSA barrier. Interview results indicated Latinas were aware of health benefits of MSA and motivated to engage in MSA but reported barriers (e.g., perception that MSA is for men, a taboo topic, and lack of knowledge on how to do MSA).

CONCLUSION

This study contributes to a critical gap in PA research among Latinas. Findings will inform future culturally appropriate MSA interventions in this at-risk population. Addressing MSA and aerobic PA together in future interventions will provide a more comprehensive approach to reducing PA-related health disparities in Latinas than aerobic PA alone.

Efficacy of eHealth interventions to reduce depression symptoms in individuals with obesity: a systematic review of randomized controlled trials

Introduction

Obesity and depression are inter-related health concerns, demanding a high level of treatment and costs in the health care system. The development of eHealth interventions that simultaneously address obesity and mental health can be supportive in this regard. However, evidence of the efficacy of eHealth interventions in the treatment of depression symptoms in individuals with obesity is lacking. The aim of this systematic literature review is to evaluate the efficacy of existing eHealth interventions for individuals with obesity that target depression symptoms.

Methods

We systematically searched electronic databases (Cochrane Library, PubMed, Scopus) to identify studies published in English between January 2016 and January 2023, that focused on eHealth interventions, targeting depression symptoms in individuals with obesity people. Exclusion criteria were study objectives that (1) focused specifically on one or more metabolic comorbidities of individuals with obesity, e.g., hypertension, hyperlipidemia, diabetes; (2) focused specifically on eating disorders comorbidities e.g., binge eating disorder, and (3) focused specifically on patients before or after bariatric surgery.

Results

The database search identified 214 records. Six articles were included in this review. Sample sizes ranged from 70 to 1267 participants of ages 18-60 years. All included studies were randomized controlled trials. Two of the six included studies were web-based interventions guided either by medical doctors or psychologists. All interventions included video, printed materials, and interactive parts of which two studies integrated elements of Cognitive Behavioural Therapy and Social Cognitive Therapy. The findings showed that eHealth treatment services, supported and guided throughout the intervention had high acceptance and efficacy in the reduction of depression symptoms among individuals with obesity.

Conclusion

EHealth interventions that address and target both mental and physical health with interactive strategies calls for better efficacy in the reduction of depression symptoms. Future eHealth interventions that target depression symptoms in individuals with obesity should integrate digital strategies that address both mental and physical health through interactive modules.

The Hombres Saludables Physical Activity Web-Based and Mobile Phone Intervention: Pilot Randomized Controlled Trial With Latino Men

BACKGROUND

Owing to structural-level, interpersonal-level, and individual-level barriers, Latino men have disproportionately high rates of physical inactivity and experience related chronic diseases. Despite these disparities, few physical activity (PA) interventions are culturally targeted for Latino men.

OBJECTIVE

This study reported the feasibility and acceptability of Hombres Saludables PA intervention for Latino men. We also reported the preliminary efficacy of the intervention on PA change and provided the results of the exploratory moderator and mediator analysis.

METHODS

We completed a 6-month, single-blind, pilot randomized controlled trial of Hombres Saludables with Latino men aged between 18 and 65 years. Men were randomized to either (1) a theory-driven, individually tailored, internet-based and SMS text message-based, Spanish-language PA intervention arm or (2) a nutrition and wellness attention contact control arm that was also delivered via the web and SMS text message. We assessed the primary study outcomes of feasibility using participant retention and acceptability using postintervention survey and open-ended interview questions. We measured the preliminary efficacy via change in minutes of moderate to vigorous PA per week using ActiGraph wGT3X-BT accelerometry (primary measure) and self-reported minutes per week using 7-day Physical Activity Recall. Participants completed the assessments at study enrollment and after 6 months.

RESULTS

The 38 participants were predominantly Dominican (n=8, 21%) or Guatemalan (n=5, 13%), and the mean age was 38.6 (SD 12.43) years. Retention rates were 91% (21/23) for the PA intervention arm and 100% (15/15) for the control arm. Overall, 95% (19/20) of the intervention arm participants reported that the Hombres study was somewhat to very helpful in getting them to be more physically active. Accelerometry results indicated that participants in the intervention group increased their PA from a median of 13 minutes per week at study enrollment to 34 minutes per week at 6 months, whereas the control group participants showed no increases. On the basis of self-reports, the intervention group was more likely to meet the US PA guidelines of 150 minutes per week of moderate to vigorous PA at 6-month follow-up, with 42% (8/19) of the intervention participants meeting the PA guidelines versus 27% (4/15) of the control participants (odds ratio 3.22, 95% CI 0.95-13.69). Exploratory analyses suggested conditional effects on PA outcomes based on baseline stage of motivational readiness, employment, and neighborhood safety.

CONCLUSIONS

The PA intervention demonstrated feasibility and acceptability. Results of this pilot study indicate that the Hombres Saludables intervention is promising for increasing PA in Latino men and suggest that a fully powered trial is warranted. Our technology-based PA intervention provides a potentially scalable approach that can improve health in a population that is disproportionately affected by low PA and related chronic disease.

George SM, Crane TE. Feasibility and Acceptability of a Text Message Intervention to Promote Adherence to Nutrition and Physical Activity Guidelines in a Predominantly Hispanic Sample of Cancer Survivors and Their Informal Caregivers: Results from a Pilot Intervention Trial

Hispanic cancer survivors face unique barriers to meeting American Cancer Society (ACS) nutrition and physical activity guidelines, which reduce the risk of cancer recurrence and mortality and improve quality of life. This pilot intervention trial evaluated the feasibility and acceptability of a two-week ACS guideline-based nutrition and physical activity text message intervention in a predominantly Hispanic sample of cancer survivors and their informal caregivers. A mixed methods approach was used to assess feasibility and acceptability of the intervention. Feasibility and acceptability were measured by meeting a-priori cut-offs of >80% for recruitment, retention, and text message response rate. Participants also completed a semi-structured exit interview by telephone that assessed intervention components. Thirteen cancer survivors and six caregivers (n = 19) participated in this pilot study; 78% self-identified as Hispanic. Mean time since treatment completion for survivors was 11.9 years (SD 8.4), and 67% had breast cancer. Cancer survivors had a higher acceptability rate for physical activity (94%) compared to nutrition messages (86%), whereas equal acceptability rates were observed for both types of messages among caregivers (91%). Texting interventions are a feasible, acceptable, and a cost-effective strategy that have the potential to promote lifestyle behavior change among Hispanic cancer survivors and caregivers.

Interventions for improving health literacy in migrants

BACKGROUND

Health literacy (HL) is a determinant of health and important for autonomous decision-making. Migrants are at high risk for limited HL. Improving HL is important for equitable promotion of migrants' health.

OBJECTIVES

To assess the effectiveness of interventions for improving HL in migrants. To assess whether female or male migrants respond differently to the identified interventions.

SEARCH METHODS

We ran electronic searches to 2 February 2022 in CENTRAL, MEDLINE, Embase, PsycInfo and CINAHL. We also searched trial registries. We used a study filter for randomised controlled trials (RCTs) (RCT classifier).

SELECTION CRITERIA

We included RCTs and cluster-RCTs addressing HL either as a concept or its components (access, understand, appraise, apply health information).

DATA COLLECTION AND ANALYSIS

We used the methodological procedures recommended by Cochrane and followed the PRISMA-E guidelines. Outcome categories were: a) HL, b) quality of life (QoL), c) knowledge, d) health outcomes, e) health behaviour, f) self-efficacy, g) health service use and h) adverse events. We conducted meta-analysis where possible, and reported the remaining results as a narrative synthesis.

MAIN RESULTS

We included 28 RCTs and six cluster-RCTs (8249 participants), all conducted in high-income countries. Participants were migrants with a wide range of conditions. All interventions were adapted to culture, language and literacy. We did not find evidence that HL interventions cause harm, but only two studies assessed adverse events (e.g. anxiety). Many studies reported results for short-term assessments (less than six weeks after total programme completion), reported here. For several comparisons, there were also findings at later time points, which are presented in the review text. Compared with no HL intervention (standard care/no intervention) or an unrelated HL intervention (similar intervention but different information topic) Self-management programmes (SMP) probably improve self-efficacy slightly (standardised mean difference (SMD) 0.28, 95% confidence interval (CI) 0.06 to 0.50; 2 studies, 333 participants; moderate certainty). SMP may improve HIV-related HL (understanding (mean difference (MD) 4.25, 95% CI 1.32 to 7.18); recognition of HIV terms (MD 3.32, 95% CI 1.28 to 5.36)) (1 study, 69 participants). SMP may slightly improve health behaviours (3 studies, 514 participants), but may have little or no effect on knowledge (2 studies, 321 participants) or subjective health status (MD 0.38, 95% CI -0.13 to 0.89; 1 study, 69 participants) (low certainty). We are uncertain of the effects of SMP on QoL, health service use or adverse events due to a lack of evidence. HL skills building courses (HLSBC) may improve knowledge (MD 10.87, 95% CI 5.69 to 16.06; 2 studies, 111 participants) and any generic HL (SMD 0.48, 95% CI 0.20 to 0.75; 2 studies, 229 participants), but may have little or no effect on depression literacy (MD 0.17, 95% CI -1.28 to 1.62) or any health behaviour (2 studies, 229 participants) (low certainty). We are uncertain if HLSBC improve QoL, health outcomes, health service use, self-efficacy or adverse events, due to very low-certainty or a lack of evidence. Audio-/visual education without personal feedback (AVE) probably improves depression literacy (MD 8.62, 95% CI 7.51 to 9.73; 1 study, 202 participants) and health service use (MD -0.59, 95% CI -1.11 to -0.07; 1 study, 157 participants), but probably has little or no effect on health behaviour (risk ratio (RR) 1.07, 95% CI 0.91 to 1.25; 1 study, 135 participants) (moderate certainty). AVE may improve self-efficacy (MD 3.51, 95% CI 2.53 to 4.49; 1 study, 133 participants) and may slightly improve knowledge (MD 8.44, 95% CI -2.56 to 19.44; 2 studies, 293 participants) and intention to seek depression treatment (MD 1.8, 95% CI 0.43 to 3.17), with little or no effect on depression (SMD -0.15, 95% CI -0.40 to 0.10) (low certainty). No evidence was found for QoL and adverse events. Adapted medical instruction may improve understanding of health information (3 studies, 478 participants), with little or no effect on medication adherence (MD 0.5, 95% CI -0.1 to 1.1; 1 study, 200 participants) (low certainty). No evidence was found for QoL, health outcomes, knowledge, health service use, self-efficacy or adverse events. Compared with written information on the same topic SMP probably improves health numeracy slightly (MD 0.7, 95% CI 0.15 to 1.25) and probably improves print literacy (MD 9, 95% CI 2.9 to 15.1; 1 study, 209 participants) and self-efficacy (SMD 0.47, 95% CI 0.3 to 0.64; 4 studies, 552 participants) (moderate certainty). SMP may improve any disease-specific HL (SMD 0.67, 95% CI 0.27 to 1.07; 4 studies, 955 participants), knowledge (MD 11.45, 95% CI 4.75 to 18.15; 6 studies, 1101 participants) and some health behaviours (4 studies, 797 participants), with little or no effect on health information appraisal (MD 1.15, 95% CI -0.23 to 2.53; 1 study, 329 participants) (low certainty). We are uncertain whether SMP improves QoL, health outcomes, health service use or adverse events, due to a lack of evidence or low/very low-certainty evidence. AVE probably has little or no effect on diabetes HL (MD 2, 95% CI -0.15 to 4.15; 1 study, 240 participants), but probably improves information appraisal (MD -9.88, 95% CI -12.87 to -6.89) and application (RR 1.51, 95% CI 1.29 to 1.77) (1 study, 608 participants; moderate certainty). AVE may slightly improve knowledge (MD 8.35, 95% CI -0.32 to 17.02; low certainty). No short-term evidence was found for QoL, depression, health behaviour, self-efficacy, health service use or adverse events. AVE compared with another AVE We are uncertain whether narrative videos are superior to factual knowledge videos as the evidence is of very low certainty. Gender differences Female migrants' diabetes HL may improve slightly more than that of males, when receiving AVE (MD 5.00, 95% CI 0.62 to 9.38; 1 study, 118 participants), but we do not know whether female or male migrants benefit differently from other interventions due to very low-certainty or a lack of evidence.

AUTHORS' CONCLUSIONS

Adequately powered studies measuring long-term effects (more than six months) of HL interventions in female and male migrants are needed, using well-validated tools and representing various healthcare systems.

The STAR-MAMA RCT: Bilingual Mobile Health Coaching for Postpartum Weight Loss

INTRODUCTION

Gestational diabetes and overweight during pregnancy are associated with future type 2 diabetes. Postpartum weight loss can reduce diabetes risk. However, effective interventions for postpartum weight loss are lacking, in particular for Latina populations, despite their disproportionate burdens of gestational diabetes, overweight, and diabetes.

STUDY DESIGN

This was a community-based RCT.

SETTING/PARTICIPANTS

Researchers recruited pregnant individuals with gestational diabetes or BMI>25 kg/m2 from safety-net health care settings and Women, Infants, and Children offices in Northern California in 2014-2018. Of 180 individuals randomized to intervention (n=89) or control (n=91), 78% identified as Latina, 61% were primarily Spanish speaking, and 76% perceived their diabetes risk to be low.

INTERVENTION

The intervention consisted of a 5-month postpartum telephone-based health coaching intervention delivered in English or Spanish.

MAIN OUTCOME MEASURES

Data were collected through surveys at enrollment and 9-12 months after delivery and chart review up to 12 months after delivery. The primary outcome, weight change from prepregnancy to 9-12 months after delivery, was compared between the groups, overall and within strata defined a priori according to language (Spanish or English) and diabetes risk perception (none/slight or moderate/high).

RESULTS

The intent-to-treat estimated intervention effect was +0.7 kg (95% CI= -2.4 kg, +3.8 kg; p=0.67). In stratified analyses, intervention effects remained nonsignificant but varied in direction: effects were favorable among English speakers and those with higher perceived diabetes risk, and unfavorable among Spanish speakers and those with lower perceived risk. Analyses were conducted in 2021-2022.

CONCLUSIONS

A postpartum health coaching intervention, designed for low-income Latina women at increased risk for diabetes, did not reduce postpartum weight gain. Intervention effects were nonsignificantly more favorable among English speakers versus Spanish speakers, and among those who perceived their diabetes risk to be high versus low.

Social cognitive theory-based health promotion in primary care practice: A scoping review

Background

Using a theoretical perspective to guide research design and implementation can result in a coherent preventative intervention model. Among theoretical frameworks, Bandura's Social Cognitive Theory (SCT) is particularly useful for studies focused on behavior change in health promotion research.

Objective

This scoping review explored and summarized the current evidence on health promotion interventions that integrated constructs of Social Cognitive Theory and the outcome of those interventions in primary care settings.

Method

ology: We conducted this scoping review using the PRISMA scoping review guidelines; we reviewed articles from five electronic databases and additional sources that were peer-reviewed journal articles reporting interventions applying SCT constructs and synthesized the outcomes following the interventions.

Results

Among 849 retrieved from multiple sources, 39 articles met our eligibility criteria. Most studies (n = 19) were conducted in the United States. Twenty-six studies followed a randomized control trial design. Most studies (n = 26) recruited participants utilizing the primary care network. All 39 studies mentioned "self-efficacy" as the most utilized construct of SCT to determine how behavior change operates, followed by "observational learning" through role models. Twenty-three studies integrated individual (face-to-face) or peered group-based counseling-training programs; eight interventions used telephonic health coaching by a specialist; eight studies used audio-visual mediums. All included studies reported positive health outcomes following the intervention, including increased self-reported moderate-to-vigorous physical activity, increased Knowledge of dietary intake, high-risk behaviors such as STIs transmission, adapting to a healthy lifestyle, and adherence to post-transplant medication.

Conclusion

Current evidence suggests that SCT-based interventions positively impact health outcomes and intervention effectiveness. The results of this study indicate the importance of incorporating and assessing several conceptual structures of behavioral theories when planning any primary care health promotion practice.

Are Social Media Interventions for Health Behavior Change Efficacious among Populations with Health Disparities?: A Meta-Analytic Review

While prior reviews have identified positive effects of social media interventions for health behavior change generally, it is unclear whether these effects persist in traditionally underrepresented populations that are at disproportionate risk of disease. The current meta-analysis examined the effectiveness of social media interventions for health behavior change among populations with health disparities. We analyzed 17 studies with a cumulative N = 3,561. Social media interventions had a significant moderate-sized effect on behavior change among populations with health disparities (d = 0.303, 95% CI: 0.156, 0.460, p < .001), and there was significant heterogeneity across the studies (Q = 64.48, p < .001, I2 = 75.19). Exploratory moderator analyses revealed larger effects in studies with smaller sample size (p < .05) and those using additional intervention channels, including e-mail and telephone (p < .05). Findings suggest that social media interventions may be a promising intervention tool for stimulating behavior change among populations with health disparities, but several gaps remain in the literature. Public health professionals and other health communicators should further explore ways to increase both the reach and impact of social media interventions among populations with health disparities.

Pasos Hacia La Salud II: study protocol for a randomized controlled trial of a theory- and technology-enhanced physical activity intervention for Latina women, compared to the original intervention

Background

Latinas are at increased risk for many lifestyle-related chronic diseases and are one of the least physically active populations in the US Innovative strategies are needed to help Latinas achieve the health benefits associated with physical activity (PA). This manuscript describes the study protocol of the Pasos Hacia La Salud II Study, which builds upon our previous research to test an enhanced individually-tailored, text-message and website-delivered, Spanish-language intervention (enhanced intervention), in comparison to the original web-based Pasos Hacia La Salud Intervention (original intervention).

Methods

Sedentary Latinas between the ages of 18–65 will be recruited and will complete an orientation and baseline assessments. Participants will be subsequently randomized to the original intervention, or the Enhanced Intervention, which has greater targeting of theoretical constructs such as self-efficacy, enjoyment, and social support, and which uses text messages and more dynamic and refined website features to encourage increased website use. Using a linear mixed effects regression model, we will simultaneously estimate the intervention effects on mean accelerometer-measured hours/week of moderate-to-vigorous PA (MVPA) at 6, 12, 18, and 24 months, with a subject-specific intercept (intent-to-treat sample). Change in self-reported MVPA, measured via the 7-day Physical Activity Recall, will be assessed as a secondary outcome using a similar model. We will investigate potential mediators of the intervention effect using a multiple mediation approach, and potential moderators by evaluating potential interactions. As an exploratory outcome, we will study the differences (among both study arms) in cost, in US dollars, per minute increases in weekly mean MVPA.

Discussion

The original Pasos PA intervention showed efficacy in helping Latinas increase PA; we expect the Enhanced Intervention to help a larger proportion of participants to increase and maintain their PA long term. This web- and text-based enhanced intervention could have great reach and dissemination potential, which could be capitalized on in the future to help to advance health equity. Adaptations made in response to the COVID-19 pandemic are also described in this manuscript.

Two-year outcomes of Faith in Action/Fe en Acción: a randomized controlled trial of physical activity promotion in Latinas

BACKGROUND

Latina women are less likely to report engaging in leisure-time physical activity (PA) than non-Latina white women. This study evaluated the 24-month impact of a faith-based PA intervention targeting Latinas.

METHODS

The study is a cluster randomized controlled trial of a PA intervention or cancer screening comparison condition, with churches as the randomization unit. A total of 436 Latinas (aged 18-65 years) from 16 churches who engaged in low levels of self-report and accelerometer-based PA were enrolled. The experimental condition was a 24-month PA intervention, with in-person classes, social support, and environmental changes, led by community health workers (i.e., promotoras). At baseline, 12-, and 24 months, we assessed changes in accelerometer-based and self-reported moderate to vigorous physical activity (MVPA; primary outcomes). Secondary outcomes were light intensity activity, sedentary time, body mass index (BMI), and waist circumference.

RESULTS

After adjusting for sociodemographic factors, a mixed effects analysis found significant increases in self-reported leisure time MVPA (p < 0.005) and marginal increases in accelerometer-assessed MVPA (p < 0.08) 24 months post-baseline in the intervention compared to the attention-control condition. Data showed significant associations between PA class attendance and engaging in MVPA as assessed by self-report and accelerometry. No significant changes were found for light activity, sedentary time, BMI, or waist circumference.

CONCLUSIONS

Participants who attended the PA classes at least once a month engaged in significantly higher MVPA compared to those who did not. Maximizing engagement and maintenance strategies to enhance PA maintenance could contribute to important long-term health benefits.

Behavioral Counseling Interventions to Promote a Healthy Diet and Physical Activity for Cardiovascular Disease Prevention in Adults Without Known Cardiovascular Disease Risk Factors: Updated Evidence Report and Systematic Review for the US Preventive Services Task Force

IMPORTANCE

Unhealthful dietary patterns, low levels of physical activity, and high sedentary time increase the risk of cardiovascular disease.

OBJECTIVE

To synthesize the evidence on benefits and harms of behavioral counseling interventions to promote a healthy diet and physical activity in adults without known cardiovascular disease (CVD) risk factors to inform a US Preventive Services Task Force recommendation.

DATA SOURCES

MEDLINE, PsycINFO, and the Cochrane Central Register of Controlled Trials through February 2021, with ongoing surveillance through February 2022.

STUDY SELECTION

Randomized clinical trials (RCTs) of behavioral counseling interventions targeting improved diet, increased physical activity, or decreased sedentary time among adults without known elevated blood pressure, elevated lipid levels, or impaired fasting glucose.

DATA EXTRACTION AND SYNTHESIS

Independent data abstraction and study quality rating and random effects meta-analysis.

MAIN OUTCOMES AND MEASURES

CVD events, CVD risk factors, diet and physical activity measures, and harms.

RESULTS

One-hundred thirteen RCTs were included (N = 129 993). Three RCTs reported CVD-related outcomes: 1 study (n = 47 179) found no significant differences between groups on any CVD outcome at up to 13.4 years of follow-up; a combined analysis of the other 2 RCTs (n = 1203) found a statistically significant association of the intervention with nonfatal CVD events (hazard ratio, 0.27 [95% CI, 0.08 to 0.88]) and fatal CVD events (hazard ratio, 0.31 [95% CI, 0.11 to 0.93]) at 4 years. Diet and physical activity behavioral counseling interventions were associated with small, statistically significant reductions in continuous measures of blood pressure (systolic mean difference, -0.8 [95% CI, -1.3 to -0.3]; 23 RCTs [n = 57 079]; diastolic mean difference, -0.4 [95% CI, -0.8 to -0.0]; 24 RCTs [n = 57 148]), low-density lipoprotein cholesterol level (mean difference, 2.2 mg/dL [95% CI, -3.8 to -0.6]; 15 RCTs [n = 6350]), adiposity-related outcomes (body mass index mean difference, -0.3 [95% CI, -0.5 to -0.1]; 27 RCTs [n = 59 239]), dietary outcomes, and physical activity at 6 months to 1.5 years of follow-up vs control conditions. There was no evidence of greater harm among intervention vs control groups.

CONCLUSIONS AND RELEVANCE

Healthy diet and physical activity behavioral counseling interventions for persons without a known risk of CVD were associated with small but statistically significant benefits across a variety of important intermediate health outcomes and small to moderate effects on dietary and physical activity behaviors. There was limited evidence regarding the long-term health outcomes or harmful effects of these interventions.

Increases in Muscle-Strengthening Activities Among Latinas in Seamos Saludables

BACKGROUND

Only 17% of Latinas meet national physical activity (PA) guidelines for both moderate-to-vigorous aerobic and muscle-strengthening PA. Additional health benefits are derived from the combination of aerobic and muscle-strengthening PA (vs. aerobic alone), yet there is paucity in research on muscle-strengthening activity in Latinas. The aim of this study was to examine changes in muscle-strengthening activity from baseline to 6 and 12 months in Seamos Saludables, a 12-month PA randomized controlled trial for Latinas.

METHODS

A secondary data analysis was conducted among 131 Latinas ages 18-65 years, who were randomized to either a PA Intervention or a Wellness Control. Self-reported muscle-strengthening exercise was measured at baseline, 6 months, and 12 months via adapted muscle-strengthening questions from the Behavioral Risk Factor Surveillance System.

RESULTS

There was a 16-minute/week difference in median minute/week of muscle-strengthening activity between Intervention and Wellness at 6 months (SE = 7.91, p = .04) and 45-minute/week difference at 12 months (SE = 25.80, p = .06) adjusting for baseline. Significantly more PA Intervention participants met muscle-strengthening guidelines of 2 or more days/week at 6 months versus Wellness Control participants (odds ratio [OR] = 4.29, 95% confidence interval [CI] = [1.03, 17.84]).

CONCLUSION

Results from the current study showed that Latinas engaged in muscle-strengthening activity in an intervention that emphasized primarily aerobic PA outcomes, suggesting they may be interested in engaging in muscle-strengthening activities. Future interventions targeting both aerobic and muscle-strengthening activity could achieve greater health improvements and help more Latinas reach the full national PA guidelines.ClinicalTrials.gov Identifier.

Evaluating the Dissemination and Implementation of a Community Health Worker-Based Community Wide Campaign to Improve Fruit and Vegetable Intake and Physical Activity among Latinos along the U.S.-Mexico Border

This study evaluated the dissemination and implementation of a culturally tailored community-wide campaign (CWC), Tu Salud ¡Si Cuenta! (TSSC), to augment fruit and vegetable (FV) consumption and physical activity (PA) engagement among low-income Latinos of Mexican descent living along the U.S.-Mexico Border in Texas. TSSC used longitudinal community health worker (CHW) home visits as a core vehicle to enact positive change across all socioecological levels to induce behavioral change. TSSC's reach, effectiveness, adoption, implementation, and maintenance (RE-AIM) was examined. A dietary questionnaire and the Godin-Shepherd Exercise Questionnaire measured program effectiveness on mean daily FV consumption and weekly PA engagement, respectively. Participants were classified based on CHW home visits into "low exposure" (2-3 visits) and "high exposure" (4-5 visits) groups. The TSSC program reached low-income Latinos (n = 5686) across twelve locations. TSSC demonstrated effectiveness as, compared to the low exposure group, the high exposure group had a greater FV intake (mean difference = +0.65 FV servings daily, 95% CI: 0.53-0.77) and an increased PA (mean difference = +185.6 MET-minutes weekly, 95% CI: 105.9-265.4) from baseline to the last follow-up on a multivariable linear regression analysis. Multivariable logistic regression revealed that the high exposure group had higher odds of meeting both FV guidelines (adjusted odds ratio (AOR) = 2.03, 95% CI: 1.65-2.47) and PA guidelines (AOR = 1.36, 95% CI: 1.10-1.68) at the last follow-up. The program had a 92.3% adoption rate, with 58.3% of adopting communities meeting implementation fidelity, and 91.7% of communities maintaining TSSC. TSSC improved FV consumption and PA engagement behaviors among low-income Latinos region wide. CHW delivery and implementation funding positively influenced reach, effectiveness, adoption, and maintenance, while lack of qualified CHWs negatively impacted fidelity.

Culturally adapting internet- and mobile-based health promotion interventions might not be worth the effort: a systematic review and meta-analysis

Health promotion interventions offer great potential in advocating a healthy lifestyle and the prevention of diseases. Some barriers to communicating health promotion to people of certain cultural groups might be overcome via the internet- and mobile-based interventions (IMI). This systematic review and meta-analysis aims to explore the effectiveness of culturally adapted IMI for health promotion interventions among culturally diverse populations. We systematically searched on Cochrane Central Register of Controlled Trials (CENTRAL), EbscoHost/MEDLINE, Ovid/Embase, EbscoHost/PsychINFO, and Web of Science databases in October 2020. Out of 9438 records, 13 randomized controlled trials (RCT) investigating culturally adapted health promotion IMI addressing healthy eating, physical activity, alcohol consumption, sexual health behavior, and smoking cessation included. From the included studies 10,747 participants were eligible. Culturally adapted IMI proved to be non-superior over active control conditions in short- (g = 0.10, [95% CI -0.19 to 0.40]) and long-term (g = 0.20, [95% CI -0.11 to 0.51]) in promoting health behavior. However, culturally adapted IMI for physical activity (k = 3, N = 296) compared to active controls yielded a beneficial effect in long-term (g = 0.48, [95%CI 0.25 to 0.71]). Adapting health promotion IMI to the cultural context of different cultural populations seems not yet to be recommendable given the substantial adaption efforts necessary and the mostly non-significant findings. However, these findings need to be seen as preliminary given the limited number of included trials with varying methodological rigor and the partly substantial between-trial heterogeneity pointing in the direction of potentially useful culturally adapted IMI which now need to be disentangled from the less promising approaches.PROSPERO registration number: 42020152939.

A multiple technology-based physical activity intervention for Latina adolescents in the USA: randomized controlled trial study protocol for Chicas Fuertes

Background

Latina adolescents in the USA report some of the lowest rates of physical activity of any demographic subgroup; this is paralleled by a markedly higher lifetime risk of obesity, type 2 diabetes, and other conditions related to inactivity. Despite this, to date, no fully powered clinical trials have tested physical activity interventions specifically for this population. High use of mobile technologies (including text messages, smartphone apps, and social media) suggests this could be an appropriate intervention channel, while also having potential for broad reach. This paper describes the protocol for Chicas Fuertes, a fully powered randomized trial of a mobile technology-based physical activity intervention for Latina adolescents.

Methods

We plan to recruit 200 Latina teens (age 13–18) in San Diego, CA, currently engaging in ≤ 150 min/week of moderate-to-vigorous physical activity (MVPA) to be assigned 1:1 to the intervention or control groups. Those randomly assigned to the intervention group receive a one-on-one goal setting session followed by 6 months of mobile technology-based intervention, including a personalized website, Fitbit activity tracker and app, individually tailored text messages based on Fitbit data, and daily intervention content on Instagram. Those randomized to the control group receive only a Fitbit activity tracker. The main outcome is change in weekly minutes of MVPA from baseline to 6 months, measured both objectively (ActiGraph accelerometers and Fitbit Inspire HR) and subjectively (7-Day Physical Activity Recall Interview). Additional outcomes are maintenance of activity change at 12 months and changes in psychosocial constructs, including social support and self-efficacy, engagement with mobile technology channels, and costs of intervention delivery. We are also examining the potential mediators and moderators of the intervention. The efficacy of the intervention is analyzed using a mixed effects regression model, adjusting for any potential confounders not balanced by randomization. All analyses of accelerometer measured MVPA are also adjusted for wear time.

Discussion

The Chicas Fuertes trial uses widely available mobile technologies to target critical health behavior, physical activity, in Latina teens, a population with a high lifetime risk of lifestyle-related diseases. The results will speak to the efficacy and acceptability of the intervention, which has the potential for broad dissemination.

Use of a Meter With Color-Range Indicators and a Mobile Diabetes Management App Improved Glycemic Control and Patient Satisfaction in an Underserved Hispanic Population: "Tu Salud"-A Randomized Controlled Partial Cross-Over Clinical Study

OBJECTIVE

To demonstrate the clinical value of OneTouch (OT) Verio Flex glucose meter used in combination with a Spanish-language version of the OT Reveal mobile application (app) to support diabetes care and improve glycemic control in an underserved Hispanic population with type 2 diabetes.

RESEARCH DESIGN AND METHODS

Test subjects (n = 81) used the meter and app for 12 weeks, while a randomized control group (n = 39) used their own glucose meters without connection to an app. Thereafter, test subjects continued the same regimen for an additional 12 weeks to determine the durability of effect, and control subjects crossed over to use the new meter and app.

RESULTS

Test subjects experienced a mean reduction in A1C of 1.0% after 12 weeks (P <0.001), a statistically significant greater reduction than in control subjects (P = 0.045). The improvement in A1C in test subjects was sustained over the next 12 weeks. Crossed-over subjects also demonstrated significant improvements in A1C (P <0.001). Mean blood glucose was reduced significantly without an increase in hypoglycemia, and results in range increased over 12 weeks of meter and mobile app use. Results were independent of subjects' numeracy skills. Subjects using the new meter and app reacted favorably to the tools and expressed improvements in their diabetes treatment satisfaction based on Diabetes Treatment Satisfaction Questionnaire-Change scores.

CONCLUSION

Use of the OT meter and a Spanish-language version of its diabetes management app in an underserved population helped participants achieve a sustained improvement in glycemic control. The tools were well received by the subjects and may have important utility in other low-numeracy, low-literacy populations.

Physical activity interventions among culturally and linguistically diverse populations: a systematic review

OBJECTIVES

To systematically review physical activity interventions among culturally and linguistically diverse (CALD) populations and explore the strategies used to recruit CALD populations, the cultural adaptations made in these interventions, and the cultural adaptations used among successful interventions.

DESIGN

Four electronic databases (Embase, MEDLINE, CENTRAL, and CINAHL) was searched in March 2017 and re-run in January 2018. Manual screening of the reference lists of the included studies was also conducted. Eligibility criteria for inclusion in the systematic review were: intervention studies (e.g. controlled and non-controlled studies), physical activity as primary outcome and as the only health behaviour targeted, culturally and linguistically diverse population of interest, published in English, and targeted adult populations (i.e. aged ≥18).

RESULTS

A total of 19 articles were included in this review, comprising 15 unique studies. Most studies targeted Latino populations, published in the United States, and targeted women. An array of recruitment strategies were used, such as recruiting from religious establishments or religious and cultural events, and community organisations and events. The majority of studies made cultural adaptations to their intervention to suit the CALD population of interest, however, the level of detail of reported adjustments was limited. Successful interventions were those that generally included community consultation to inform their intervention, language adjustments, community health workers/bilingual/bicultural personnel for intervention delivery, recruitment, and data-collection, and using culturally-relevant intervention material.

CONCLUSIONS

Although many studies included in this review reported increases in physical activity at follow-up, the results need to be interpreted with caution due to the lower level of methodological quality and reporting on study methodology. Future interventions designed for CALD populations should be of greater methodological quality and also provide a greater level of transparency in terms of the cultural adaptations that have been made to the intervention.

Physical Activity Adoption and Maintenance Among Breast Cancer Survivors: A Randomized Trial of Peer Mentoring

BACKGROUND

Peer support can extend the reach of physical activity (PA) interventions. In previous studies, peer support via weekly counseling calls increased PA at 3 and 6 months among breast cancer survivors, compared to contact control. However, effects were attenuated at 6 months. Interventions targeting PA maintenance among cancer survivors are limited. Hence, we extended prior work to identify effective PA maintenance interventions.

PURPOSE

Following a 3-month PA intervention, the study compared the effects of three 6-month interventions on PA at 12 months.

METHODS

One hundred and sixty-one inactive breast cancer survivors participated in a 12-month randomized controlled trial. Intervention delivery was uniform for the first 3-months: all participants received a weekly call with their peer coach to encourage PA. Following month 3, participants self-monitored PA and received feedback reports (Reach Plus) or additionally received, a monthly phone call (Reach Plus Phone), or weekly text message (Reach Plus Message). Moderate-to-vigorous PA (MVPA) was measured using self-report (7 Day PAR) and accelerometry at baseline, 3, 6, 9, and 12 months.

RESULTS

At 3 months, there were significant within group increases in self-reported and objectively measured MVPA with no between-group differences (ps > .05). At 6 months, adjusted longitudinal models showed that Reach Plus Message reported an additional 23.83 (SD = 6.33, f2 = .12) min/week of MVPA and Reach Plus Phone reported an additional 18.14 min/week (SD = 5.15, f2 =.16) versus Reach Plus. Results were similar at 9 months. At 12 months, Reach Plus Message and Reach Plus Phone both out-performed Reach Plus (ps = .04 and .05 respectively and effect sizes f2 = .11 and f2 = .21 respectively). Accelerometer data showed similar patterns: Reach Plus Message and Reach Plus Phone out-performed Reach Plus at 6 (f2 = .20) and 9 months (f2 = .09).

CONCLUSION

Phone calls from peer mentors and text messaging can support PA maintenance among breast cancer survivors.

Physical activity outcomes from a randomized trial of a theory- and technology-enhanced intervention for Latinas: the Seamos Activas II study

Latina women report disproportionately high and increasing prevalence of chronic health conditions (obesity, diabetes) related to low physical activity levels. Efforts to date at addressing high rates of physical inactivity in this at-risk population have shown modest success. The original Seamos Saludables (sample size N = 266) was a culturally and linguistically adapted, print-based physical activity intervention that showed significant increases in moderate to vigorous physical activity (MVPA) from baseline to 6 months. However, only 11% of intervention participants reached the national PA guidelines of ≥ 150 min/week of aerobic MVPA. The current study tests the original Seamos Saludables intervention (Original Intervention) against an enhanced iteration Seamos Activas II (Enhanced Intervention). Study aims and intervention refinements focus on increasing the percentage of Latinas meeting national aerobic PA guidelines. For the current study (Seamos Activas II), a randomized controlled trial with (N = 199 participants) of two PA interventions (original intervention, N = 102; vs. enhanced intervention, N = 97) was conducted. Intervention refinements involved further targeting key constructs of the Social Cognitive Theory and incorporating text-message-based strategies for self-monitoring, in response to participant feedback for greater interactivity and accountability. PA assessments were conducted at baseline and 6 months. The sample was predominantly Mexican American (89%) with average age of 43.8 years (SD = 10.11) and mean BMI at baseline was 30.6 (SD = 7.56). There were significant within group increases in MVPA from baseline to 6 months (p < .05) in both Original and Enhanced Intervention arms. However, quantile regression models did not indicate significant differences in 6-month outcomes between conditions controlling for baseline, p = 0.73. There were significant differences between conditions with respect to meeting national guidelines for aerobic MVPA at 6 months, with 57% of Enhanced Intervention participants meeting guidelines compared to 44% of Original Intervention participants, OR = 1.66, 95% CI: 1.09 -2.89. Models suggest trends favoring the enhanced condition for improvements in biomarkers over 6 months. Findings indicate that the intervention enhancements likely helped more Latinas achieve nationally recommended, health enhancing PA levels than the original intervention and showed promise for improving physiological response to exercise.Trial Registration ClinicalTrials.Gov; NCT02630953.

An mHealth Physical Activity Intervention for Latina Adolescents: Iterative Design of the Chicas Fuertes Study

BACKGROUND

Only 3% of Latina teens meet the national physical activity (PA) guidelines, and these habits appear to persist into adulthood. Developing effective interventions to increase PA in Latina teens is necessary to prevent disease and reduce disparities. Mobile technologies may be especially appropriate for this population, but mobile health (mHealth) intervention content must be designed in collaboration with the target population.

OBJECTIVE

This study aims to develop an mHealth PA intervention for Latina adolescents using a multistage iterative process based on the principles of human-centered design and multiple iterations of the design phase of the IDEAS (Integrate, Design, Assess, Share) framework.

METHODS

On the basis of the feedback from a previous pilot study, the planned intervention included visual social media posts and text messaging, a commercial wearable tracker, and a primarily visual website. The development of the requested mHealth intervention components was accomplished through the following 2 phases: conducting focus groups with the target population and testing the usability of the final materials with a youth advisory board (YAB) comprising Latina adolescents. Participants for focus groups (N=50) were girls aged 13-18 years who could speak and read in English and who were recruited from local high schools and after-school programs serving a high proportion of Latinos. Facilitated discussions focused on experience with PA and social media apps and specific feedback on intervention material prototypes and possible names and logos. Viable products were designed based on their feedback and then tested for usability by the YAB. YAB members (n=4) were Latinas aged 13-18 years who were not regularly active and were recruited via word of mouth and selected through an application process.

RESULTS

The focus group discussions yielded the following findings: PA preferences included walking, running, and group fitness classes, whereas the least popular activities were running, swimming, and biking. Most participants (n=48, 96%) used some form of social media, with Instagram being the most favored. Participants preferred text messages to be sent no more than once per day, be personalized, and be positively worded. The focus group participants preferred an intervention directly targeting Latinas and social media posts that were brightly colored, included girls of all body types, and provided specific tips and information. Modified intervention materials were generally perceived favorably by the YAB members, who provided suggestions for further refinement, including the shortening of texts and the incorporation of some Spanish phrases.

CONCLUSIONS

Latina teens were generally enthusiastic about an mHealth PA intervention, provided that the materials were targeted specifically to them and their preferences. Through multiple iterations of development and feedback from the target population, we gained insight into the needs of Latina teens and joined with industry partners to build a viable final product.

mHealth Technology and CVD Risk Reduction

PURPOSE OF REVIEW

To review existing mHealth-based interventions and examine their efficacy in reducing cardiovascular disease (CVD) risk factors.

RECENT FINDINGS

A total of 50 articles are included in this review. The majority of the mHealth interventions targeted a specific CVD risk factor, while 4 addressed 2 or more CVD risk factors. Of the 9 mHealth-supported weight loss intervention trials, 4 resulted in significant weight loss. Four out of 7 RCTs targeting improvement in physical activity reported significant improvement, while 4 of the 8 mHealth-supported smoking cessation intervention trials resulted in smoking abstinence. Of the 10 mHealth-based diabetes intervention trials, 5 reported significant reductions in HbA1c; however, only 3 out of the 9 antihypertension interventions resulted in significant reductions in blood pressure. There is a growing body of literature focused on mHealth interventions that address CVD risk factors. Despite the immense potential of mHealth interventions, evidence of their efficacy in mitigating cardiovascular risk is heterogeneous.

A Tailored Web- and Text-Based Intervention to Increase Physical Activity for Latino Men: Protocol for a Randomized Controlled Feasibility Trial

Background

Latino men in the United States report low physical activity (PA) levels and related health conditions (eg, diabetes and obesity). Engaging in regular PA can reduce the risk of chronic diseases and yield many health benefits; however, there is a paucity of interventions developed exclusively for Latino men.

Objective

To address the need for culturally relevant PA interventions, this study aims to develop and evaluate Hombres Saludables, a 6-month theory-based, tailored web- and text message-based PA intervention in Spanish for Latino men. This protocol paper describes the study design, intervention, and evaluation methods for Hombres Saludables.

Methods

Latino men aged 18-65 years were randomized to either the individually tailored PA internet intervention arm or the nutrition and wellness internet control arm. The PA intervention included 2 check-in phone calls; automated SMS text messages; a pedometer; a 6-month gym membership; access to a private Facebook group; and an interactive website with PA tracking, goal setting, and individually tailored PA content. The primary outcomes were feasibility, acceptability, and efficacy (minutes per week of total moderate-to-vigorous PA assessed via the ActiGraph GT3X+ accelerometer worn at the waist and 7-day physical activity recall at baseline and 6 months). Secondary outcomes examined potential moderators (eg, demographics, acculturation, and environmental variables) and mediators (eg, self-efficacy and cognitive and behavioral processes of change) of treatment effects at 6 months post randomization.

Results

This study was funded in September 2016. Initial institutional review board approval was received in February 2017, and focus groups and intervention development were conducted from April 2017 to January 2018. Recruitment for the clinical trial was carried out from February 2018 to July 2019. Baseline data collection was carried out from February 2018 to October 2019, with a total of 43 participants randomized. Follow-up data were collected through April 2020. Data cleaning and analysis are ongoing.

Conclusions

We developed and tested protocols for a highly accessible, culturally and linguistically relevant, theory-driven PA intervention for Latino men. Hombres Saludables used an innovative, interactive, web- and text message–based intervention for improving PA among Latino men, an underserved population at risk of low PA and related chronic disease. If the intervention demonstrates feasibility, acceptability, and preliminary efficacy, we will refine and evaluate it in a larger randomized control trial.

Lapse, Relapse, and Recovery in Physical Activity Interventions for Latinas: a Survival Analysis

BACKGROUND

Physical activity (PA) research extensively focuses on initiation of PA, yet lapse and relapse among PA intervention participants are less well understood, particularly among minority populations such as Latinas in the USA. This study aimed to (1) determine the probability of lapse during two PA interventions for Latinas; (2) assess demographic, psychosocial, and environmental predictors of the amount of time until first lapse; and (3) identify factors predictive of lapse recovery.

METHODS

Data from 176 Latina intervention participants were pooled. Survival functions and Kaplan-Meier curves were used to illustrate probability of lapse. Cox proportional hazard models assessed predictors of time to lapse. Logistic regressions identified predictors of lapse recovery.

RESULTS

The probability of lapse after 1 month of starting to exercise was 18%, escalating to 34% after 4 months. Predictors of earlier lapse included various psychosocial constructs (i.e., self-efficacy and various processes of change), but none of the measured environmental factors, and only one demographic factor (≥ 2 children under 18). Increased use of consciousness raising at 2 months was associated with lower likelihood of lapse recovery, yet use of behavioral processes of change at 6 months was associated with higher likelihood of recovery.

CONCLUSIONS

Lapsing may not be pre-determined by demographic and environmental characteristics. On the other hand, skills that can be learned through interventions, such as skills to improve self-efficacy, seem important in the delay or prevention of lapses. Results pertaining to lapse recovery are less clear.

Psychosocial mediators of physical activity change in a web-based intervention for Latinas

Objective: To determine whether psychosocial constructs targeted in an online physical activity intervention for Latinas mediated changes in moderate-to-vigorous physical activity (MVPA). Method: Data were taken from a randomized trial of a web-based MVPA intervention for Latina women age 18-65 (N = 205) based on social cognitive theory and the transtheoretical model. Baseline and 6-month measures included minutes/week of MVPA (ActiGraph GT3X + accelerometers and 7-Day Physical Activity Recall Interview) and theorized mediators (self-efficacy, behavioral processes, cognitive processes, social support, enjoyment). A multiple mediation model adjusting for baseline MVPA was fit using a products of coefficients method, simultaneously testing all hypothesized mediators. Results: MVPA increased more in the intervention group than controls by 50 min/week (self-report) and 31 min/week (accelerometers). For the self-reported MVPA model, there was an intervention effect (a-path coefficient) on self-efficacy (b = 0.43, p < .01), cognitive processes (b = 0.64, p < .01), behavioral processes (b = 0.54, p < .01), and enjoyment (b = 9.91, p = .01). Changes in self-efficacy (b = 24.54, p = .03), social support from friends (b = 2.36, p = .04), and enjoyment (a = 0.74, p = .08) were associated with changes in MVPA (b-path coefficient). However, only changes in self-efficacy (b = 10.49, 95% CI [2.46, 24.54]) and enjoyment (b = 7.30, 95% CI [0.92, 21.78]) mediated the intervention effect on MVPA (ab-path coefficient). For the accelerometer-measured MVPA model, intervention effects were significant for self-efficacy (b = 0.48, p < .01), cognitive processes (b = 0.62, p < .01), and behavioral processes (b = 0.61, p < .01), yet only self-efficacy was associated with changes in MVPA (b = 4.43, p = .03), and mediated intervention effects on MVPA (b = 12.15, 95% CI [11.25, 16.34]). Conclusions: Future MVPA interventions with Latinas should target self-efficacy and enjoyment to maximize efficacy. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Applying the Electronic Health Literacy Lens: Systematic Review of Electronic Health Interventions Targeted at Socially Disadvantaged Groups

BACKGROUND

Electronic health (eHealth) has the potential to improve health outcomes. However, eHealth systems need to match the eHealth literacy needs of users to be equitably adopted. Socially disadvantaged groups have lower access and skills to use technologies and are at risk of being digitally marginalized, leading to the potential widening of health disparities.

OBJECTIVE

This systematic review aims to explore the role of eHealth literacy and user involvement in developing eHealth interventions targeted at socially disadvantaged groups.

METHODS

A systematic search was conducted across 10 databases for eHealth interventions targeted at older adults, ethnic minority groups, low-income groups, low-literacy groups, and rural communities. The eHealth Literacy Framework was used to examine the eHealth literacy components of reviewed interventions. The results were analyzed using narrative synthesis.

RESULTS

A total of 51 studies reporting on the results of 48 interventions were evaluated. Most studies were targeted at older adults and ethnic minorities, with only 2 studies focusing on low-literacy groups. eHealth literacy was not considered in the development of any of the studies, and no eHealth literacy assessment was conducted. User involvement in designing interventions was limited, and eHealth intervention developmental frameworks were rarely used. Strategies to assist users in engaging with technical systems were seldom included in the interventions, and accessibility features were limited. The results of the included studies also provided inconclusive evidence on the effectiveness of eHealth interventions.

CONCLUSIONS

The findings highlight that eHealth literacy is generally overlooked in developing eHealth interventions targeted at socially disadvantaged groups, whereas evidence about the effectiveness of such interventions is limited. To ensure equal access and inclusiveness in the age of eHealth, eHealth literacy of disadvantaged groups needs to be addressed to help avoid a digital divide. This will assist the realization of recent technological advancements and, importantly, improve health equity.

Randomized Trial of a Physical Activity Intervention for Latino Men: Activo

INTRODUCTION

Latino men experience disproportionately high rates of diseases related to low physical activity, yet they are poorly represented in physical activity intervention trials. Efforts to promote physical activity in Latina women show promising results, yet such interventions are yet to be extended to Latino men. This study tested a computer expert system‒tailored, text messaging-supported physical activity intervention for underactive Spanish-speaking Latino men compared with a control group matched for contact time. Potential predictors of intervention success were also explored.

STUDY DESIGN

Randomized trial. Participants were randomized to receive a Tailored Physical Activity Intervention (Intervention) or a Wellness Control (Control). Data were collected in 2015-2017 and analyzed in 2018-2019.

SETTING/PARTICIPANTS

Insufficiently active Latino men (n=46).

INTERVENTION

Intervention participants received a baseline counseling session and then, individually tailored print materials and text messages on a tapered schedule for 6 months. Control participants received printed wellness materials and text messages on the same schedule.

MAIN OUTCOME MEASURES

Primary outcome was a change in weekly moderate to vigorous physical activity from baseline to 6 months measured by accelerometers. Self-reported moderate to vigorous physical activity measured by the 7-day Physical Activity Recall Interview was a secondary outcome.

RESULTS

For Intervention participants, median accelerometer-measured moderate to vigorous physical activity increased from 10.0 minutes/week at baseline to 57.5 minutes/week at 6 months, whereas for Control participants, it increased from 21.0 minutes/week at baseline to 23.0 minutes/week at 6 months (p<0.05). Similar results were found for self-reported moderate to vigorous physical activity. At 6 months, 47% of Intervention participants met national guidelines of 150 minutes/week versus 25% of Control participants (p=0.15, not significant).

CONCLUSIONS

Findings suggest that an individually tailored intervention can successfully increase moderate to vigorous physical activity in underactive Latino men. Such technology-supported interventions have the potential for broad dissemination.

Design and rationale for a randomized trial of a theory- and technology- enhanced physical activity intervention for Latinas: The Seamos Activas II study

INTRODUCTION

Latina women report disproportionately high rates of physical inactivity and related chronic health conditions. Physical activity (PA) efforts to date have shown modest success in this at-risk population; thus, more effective interventions are necessary to help Latinas reach national PA guidelines and reduce related health disparities. This paper describes the design, rationale, and baseline findings from the Seamos Activas II intervention.

METHODS/DESIGN

The ongoing RCT will test the efficacy of the Seamos Saludables PA print intervention vs. a theory-and technology-enhanced version (Seamos Activas II). The purpose of the study is to increase the percentage of Latinas meeting the national PA guidelines compared to the prior trial, improve biomarkers related to disease, and extend generalizability to a broader and more representative population of Latinas (i.e. Mexican/Mexican-Americans). Intervention refinements included further targeting key constructs of Social Cognitive Theory, and incorporating interactive text message-based self-monitoring strategies. The primary outcome is change in minutes per week of MVPA measured by ActiGraph GT3X+ accelerometers at 6- and 12-months. Secondary PA outcomes assessed by the 7-Day PA Recall will be used to corroborate findings.

RESULTS

Participants (N = 199) are Latinas 18-65 years (mean = 43.8) of predominantly Mexican origin (89%). At baseline, objectively measured MVPA was 39.51 min/week (SD = 71.20, median = 10) and self-reported MVPA was 12.47 min/week (SD = 22.54, median = 0).Participants reported generally low self-efficacy and higher cognitive vs. behavioral processes of change.

CONCLUSION

Addressing interactivity and accountability through text messaging, and more rigorously targeting theoretical constructs may be key to helping Latinas achieve nationally recommended PA levels and thereby reducing health disparities.

Community-Based Prevention Programs for Disordered Eating and Obesity: Updates and Current Limitations

PURPOSE OF REVIEW

To review the status of community-based disordered eating and obesity prevention programs from 2014 to 2019.

RECENT FINDINGS

In the last 5 years, prevention programs have found success in intervening with children and parental figures in wellness centers, physical activity centers, childcare centers, workplaces, online, and over-the-phone through directly reducing disordered eating and obesity or by targeting risk factors of disordered eating and obesity. Community-based prevention programs for disordered eating and programs targeting both disordered eating and obesity were scarce, highlighting the critical need for the development of these programs. Qualities of the most effective programs were those in which parents and children were educated on physical activity and nutrition via multiple group-based sessions. Limitations of current prevention programs include few programs targeting high-risk populations, a dearth of trained community members serving as facilitators, inconsistent reporting of adherence rates, and few direct measurements of disordered eating and obesity, as well as few long-term follow-ups, precluding the evaluation of sustained effectiveness.

Physical Activity Intervention Effects on Sedentary Time in Spanish-Speaking Latinas

BACKGROUND

Latinas have high rates of sedentary behavior and related health disparities, but it is unknown if interventions to increase physical activity will also reduce sedentary time. The current study examined changes in objectively measured sedentary time among Latinas in a randomized controlled trial of a physical activity intervention.

METHODS

Spanish-speaking Latinas (N = 202) were randomized to an exercise or wellness group and wore an accelerometer at baseline, 6 months, and 12 months.

RESULTS

Participants were sedentary on an average of 8.86 hours per day (SD = 2.60) at baseline. The intervention group had significantly greater increases in sedentary time compared with the control group, with the intervention group engaging in 146 more minutes per week of sedentary time at 6 months and 254 minutes per week of sedentary time at 12 months than the control group (P = .02). The intervention effect on sedentary behavior remained after controlling for moderate to vigorous physical activity. Additionally, time spent in moderate to vigorous physical activity was positively associated with more sedentary time (P = .04).

CONCLUSION

An intervention to increase moderate to vigorous physical activity resulted in greater sedentary time, raising concerns regarding compensation and highlighting the need for interventions to address both physical activity and sedentary behavior to improve public health.

Adherence to Electronic Health Tools Among Vulnerable Groups: Systematic Literature Review and Meta-Analysis

Background

Electronic health (eHealth) tools are increasingly being applied in health care. They are expected to improve access to health care, quality of health care, and health outcomes. Although the advantages of using these tools in health care are well described, it is unknown to what extent eHealth tools are effective when used by vulnerable population groups, such as the elderly, people with low socioeconomic status, single parents, minorities, or immigrants.

Objective

This study aimed to examine whether the design and implementation characteristics of eHealth tools contribute to better use of these tools among vulnerable groups.

Methods

In this systematic review, we assessed the design and implementation characteristics of eHealth tools that are used by vulnerable groups. In the meta-analysis, we used the adherence rate as an effect size measure. The adherence rate is defined as the number of people who are repetitive users (ie, use the eHealth tool more than once). We also performed a meta-regression analysis to examine how different design and implementation characteristics influenced the adherence rate.

Results

Currently, eHealth tools are continuously used by vulnerable groups but to a small extent. eHealth tools that use multimodal content (such as videos) and have the possibility for direct communication with providers show improved adherence among vulnerable groups.

Conclusions

eHealth tools that use multimodal content and provide the possibility for direct communication with providers have a higher adherence among vulnerable groups. However, most of the eHealth tools are not embedded within the health care system. They are usually focused on specific problems, such as diabetes or obesity. Hence, they do not provide comprehensive services for patients. This limits the use of eHealth tools as a replacement for existing health care services.

Efficacy of a multi-component intervention to promote physical activity among Latino adults: A randomized controlled trial

Physical inactivity is highly prevalent in Latinos. Use of smartphone technology may improve physical activity (PA) among Latino adults. We sought to determine the efficacy of a multi-component intervention to promote PA among Latino adults. We conducted a 3-month, 2-arm randomized trial among Latino adults with one or more risk factors for cardiovascular disease (CVD). We adapted a scripted, counseling approach into text messages and combined this intervention with brief motivational interviewing delivered by telephone. We compared this intervention to a control group. Both groups received a handout on the benefits of PA. During the baseline visit, participants completed a validated medical history survey as well as an assessment of quality of life and exercise behaviors. The primary outcome was change at three months in mean steps per week. We enrolled 69 patients, 35 in the intervention arm and 34 in the control arm. The mean age of the cohort was 58.7 years (SD 6.82). At baseline, mean steps per week were 65,218.2 (SD 25420.8) for intervention participants compared to 71,581.26 (SD 26118.07) for control participants, P = 0.36. At 3 months, the change in mean steps per week was 31,184.6 (SD 26121.52) for participants randomized to the intervention compared to 15,370.9 (SD 22247.84) for those randomized to control, P = 0.045. Among Latino adults with one or more risk factors for CVD, there was an increase in mean steps per week among those randomized to an intervention, involving the use of smartphones, versus control.

Examining the Validity, Reliability, and Measurement Invariance of the Social Support for Exercise Scale among Spanish- and English- language Hispanics

The Social Support for Exercise Subscales are commonly used among Hispanic populations. The aims of this study were to test the validity and reliability of the Spanish-language version of the Social Support for Exercise Subscales, and test the invariance of the Spanish- and English-language versions. Data were from a subsample of Hispanic adults in the Cameron County Hispanic Cohort (n=1,447). A series of confirmatory factor analysis (CFA) models were used to assess the validity and reliability of the Spanish-language version of the subscales. A multi group CFA approach was used to test measurement invariance. Results indicated the Spanish-language versions of family and friend support subscales had good validity and reliability (RMSEA<.07, CFI>0.95, TLI>0.94, and SRMR<0.05). There was also evidence of measurement invariance between the Spanish- and English-language versions. These findings indicate the Spanish-language family and friend support subscales are valid and can be compared between Spanish- and English-language Hispanic respondents.

Association Between Physical Activity Intervention Website Use and Physical Activity Levels Among Spanish-Speaking Latinas: Randomized Controlled Trial

Background

The internet’s low cost and potential for high reach makes Web-based channels prime for delivering evidence-based physical activity (PA) interventions. Despite the well-studied success of internet-based PA interventions in primarily non-Hispanic white populations, evidence on Spanish-speaking Latinas’ use of such interventions is lacking. The recent rise in technology use among Latinas in the United States, a population at heightened risk for low PA levels and related conditions, suggests that they may benefit from Web-based PA interventions tailored to their cultural and language preferences.

Objective

The goal of the research was to examine participant engagement with various features of an internet-based PA intervention for Latinas and explore how use of these features was differentially associated with adoption and maintenance of PA behavior change.

Method

Pasos Hacia la Salud tested a Spanish-language, culturally adapted, individually tailored, internet-based PA intervention versus a Spanish language, internet-based, Wellness Contact Control condition for underactive Latinas (N=205, mean age 39.2 [SD 10.5] years, 84% Mexican American). These analyses examined engagement with the website and explored how use was associated with adoption and maintenance of moderate to vigorous physical activity (MVPA) behavior.

Results

Overall, participants logged on to the website an average of 22 times (SD 28) over 12 months, with intervention participants logging on significantly more than controls (29 vs 14.7, P<.001). On average, participants spent more time on the website at months 1, 4, and 6 compared to all other months, with maximum use at month 4. Both log-ins and time spent on the website were significantly related to intervention success (achieving higher mean minutes of MVPA per week at follow-up: b=.48, SE 0.20, P=.02 for objectively measured MVPA and b=.74, SE 0.34, P=.03 for self-reported MVPA at 12 months, controlling for baseline). Furthermore, those meeting guidelines by the Centers for Disease Control and Prevention for PA at 12 months (≥150 minutes per week of MVPA) logged on significantly more than those not meeting guidelines (35 vs 20 over 12 months, P=.002). Among participants in the intervention arm, goal-setting features, personal PA reports, and PA tips were the most used portions of the website. Higher use of these features was associated with greater success in the program (significantly more minutes of self-reported MVPA at 12 months controlling for baseline). Specifically, one additional use of these features per month over 12 months translated into an additional 34 minutes per week of MVPA (goals feature), 12 minutes per week (PA tips), and 42 minutes per week (PA reports).

Conclusions

These results demonstrate that greater use of a tailored, Web-based PA intervention, particularly certain features on the site, was significantly related to increased PA levels in Latinas.

A Systematic Review of Electronic and Mobile Health (e- and mHealth) Physical Activity Interventions for African American and Hispanic Women

BACKGROUND

The purpose of this systematic review was to evaluate the existing scientific literature on e- and mHealth interventions promoting physical activity (PA) among African American (AA) and Hispanic women.

METHODS

Using Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines, 5 electronic databases and gray literature sources were searched in August 2017. Inclusion criteria are published in English language peer-reviewed journals between 2000 and 2017, use of an e- or mHealth delivery strategy to promote PA, primary focus on AA or Hispanic women, and reported PA outcome data.

RESULTS

Ten articles met inclusion criteria for review, 6 studies focused on AA women and 4 studies on Hispanic women. The majority (n = 8) were pilot studies; only 2 studies were full-scale randomized controlled trials and both focused on Hispanic women. Six studies (60%) used websites as the primary method of intervention delivery, 3 studies (30%) used text messaging, and 1 study (10%) used the social networking website Facebook. In total, 70% of the studies (n = 7) reported significant within- or between-group differences for at least 1 PA outcome.

CONCLUSIONS

Findings provide preliminary support for e- and mHealth PA interventions among AA and Hispanic women. However, future large-scale, rigorously designed, randomized controlled trials are needed to further explore their effectiveness among AA and Hispanic women.

Recommendations for a Culturally Salient Web-based Physical Activity Program for African Americans

BACKGROUND

Barriers to physical activity (PA) among African Americans (AAs) have been extensively studied, yet there is limited research on innovative PA interventions designed to address them. In recent years, many studies have used the internet to promote PA, but very few have included AAs. In this study, we sought the input of AA focus groups to inform the development of a web-based Physical Activity for The Heart (PATH) program for inactive AAs.

METHODS

A qualitative design involving 4 focus groups stratified by sex and age was employed to explore AAs' needs and preferences for resources to be included in the PATH program. We employed an inductive approach to content analysis to analyze data using ATLAS.ti 7.5.

RESULTS

Sixteen women and ten men (age 30-65 years) participated in the focus groups. Participants were obese (mean BMI 32.2 ± 5.4 kg/m2) with below average confidence rating (mean 46.4 ± 19.1%) on the Barriers Self-Efficacy Scale. Three main themes emerged from the data: 1) need to see similar others engaging in PA (workout videos featuring models with relatable body size, age, ethnicity), 2) flexible PA regimen (doable at any time/setting), and 3) age and sex differences in preferences for PA resources (religion, music, intensity).

CONCLUSION

These data suggest that specific intervention components, i.e., PA models who match participants' profiles, flexibility and tailoring to age/gender groups, could improve uptake of web-based PA programs designed for inactive AAs. Therefore, a precision health approach needs to be employed when designing interventions to promote PA among inactive AAs.

Systematic Review of Physical Activity Interventions in Hispanic Adults

INTRODUCTION

Physical activity (PA) has demonstrated substantial physical and psychological benefits. However, Hispanics engage in less leisure-time PA when compared with other groups, putting them at higher risk for diseases associated with obesity, such as diabetes mellitus type 2. This literature review was conducted to identify best practices with regard to interventions designed to increase PA among Hispanic adults.

METHODS

Extensive searching located 21 randomized controlled studies conducted in the United States.

RESULTS

Common conceptual frameworks were the transtheoretical model and social cognitive theory. Most interventions used educational sessions with a variety of topics and many used promotoras to increase PA. Outcomes were predominantly examined using self-report PA measures. Walking was the most commonly reported PA behavior. Studies with significant results were those that measured moderate-to-vigorous PA and used theory to guide interventions. Male and older participants were underrepresented.

CONCLUSIONS

Effective culturally appropriate PA interventions for Hispanics adults are needed. Particular attention to intervention tailoring based on country of origin could enhance intervention effectiveness.

The effectiveness of eHealth interventions on physical activity and measures of obesity among working-age women: a systematic review and meta-analysis

Physical inactivity and obesity are modifiable risk factors for cardiovascular disease, particularly in women. eHealth interventions may increase physical activity and improve obesity-related outcomes among women. The objective of this study was to review the evidence of the effectiveness of eHealth interventions to increase moderate-to-vigorous physical activity among working-age women. The secondary objective was to examine their effectiveness on improving obesity-related outcomes. A comprehensive search strategy was developed for eight electronic databases; through July 2016. All studies consisting of >80% women of working-age (18-65 years) in high income countries were included. Multiple unblinded reviewers determined study eligibility and extracted data. Risk of bias was evaluated using the Cochrane Risk of Bias Tool and data quality using the Grading of Recommendations Assessment, Development and Evaluation approach. Data were pooled using a random-effects model. Sixty studies were included in the review of which 20 were in the meta-analysis. The meta-analysis demonstrated eHealth interventions improved moderate-to-vigorous physical activity (standard mean difference = 1.13, 95% confidence interval: 0.58, 1.68, P < 0.0001); an increase of ~25 min week^-1 . No changes were observed in obesity-related outcomes; waist circumference (P = 0.06), body mass (P = 0.05) and body mass index (P = 0.35). eHealth interventions are effective at increasing min week^-1 of moderate-to-vigorous physical activity among working-age women from high income countries.

Psychometrics of the self-efficacy for physical activity scale among a Latina women sample

Background

Even though Latinos have become a priority population for the promotion of physical activity in the United States, several widely used scales in physical activity promotion research have not been validated among this population, particularly in Spanish. This study aims to assess the validity and other psychometrics of the Self-Efficacy for Physical Activity scale among a sample of Spanish-speaking Latina women who participated in the Pasos Hacia La Salud intervention. We also explored alternatives for scale simplification.

Methods

Data from 205 women corresponding to baseline, 6-month, and 12-month time points were analyzed. Internal consistency was assessed. A series of Spearman correlations, t-tests, linear regressions, and logistic regressions were used to assess the concurrent and predictive validity of the Self Efficacy for Physical Activity scale against both self-report and accelerometer-measured physical activity, using both continuous and categorical outcome data. Item Response Theory and factor analysis methods were used to explore alternatives to simplify the scale. Psychometric tests were repeated with the simplified scale.

Results

Cronbach’s alpha for the original scale was .72, .76, and .78 for baseline, 6-month, and 12-month data respectively. All concurrent validity tests conducted with 6-month and 12-month data, but not with baseline data, were statistically significant. Self-efficacy at 6 months was also predictive of physical activity at 12 months for all tests except one. Based on plots of Option Characteristic Curves, a modified version of the scale was created. Psychometric results of the modified scale were similar to those of the original scale.

Conclusions

This study confirmed the scale’s reliability and validity, and revealed that the scale’s accuracy improves when some response items are collapsed, which is an important finding for future research among populations with low literacy levels.

Use of Web-Based Parent-Adolescent Health Promotion Program Among Puerto Ricans

BACKGROUND

Despite positive attitudes of Latinos using the Internet and the increased availability of health information resources, few studies have been conducted that examine actual use and barriers to web-based health information.

OBJECTIVE

The aim of this study was to examine whether select sociodemographic factors and technology factors (e.g., computer and Internet access) predicted use of a web-based, parent-adolescent sexual communication program or a physical activity program, entitled Cuídalos, among Puerto Rican parents.

METHODS

This study uses data from a randomized controlled trial designed to examine the long-term effectiveness of Cuídalos. Parents were recruited from community-based and school sites throughout Puerto Rico and randomly assigned to a web-based, parent-adolescent sexual communication (n = 245) or a physical activity (n = 247) program. Parents were instructed to complete the two-session program within 1 week and had access to the program for a period of 3 months. Outcomes in this secondary analysis were the number of log-ins and self-reported access during the 3-month period. Reasons for not accessing the program after the 3-month period were assessed.

RESULTS

Self-reported access after completion of the Cuídalos program and the actual number of log-ins over the intervention period were low. There were no statistically significant differences in the number of log-ins between parents who accessed Cuídalos during the 3-month time frame and those who did not (p = .28). Logistic regression analyses demonstrated that the odds of accessing Cuídalos during the 3-month period was 72% higher (OR = 1.72, 95% CI [1.08, 2.75]) among parents with a high school education or less, as compared to parents with a college education (p = .02). Similarly, Poisson regression model results indicated that, with every year increase in age, the expected number of log-ins increased by 1% (RR = 1.01, 95% CI [1.00, 1.02]); compared to those who accessed the program at home, the expected number of log-ins ranged from 10% to 27% lower for parents accessing elsewhere. Reasons for not accessing the program during the 3-month period included not having easy access to a computer (n = 134, 48.6%), or they did not know how to access the program again (n = 56, 20.3%).

DISCUSSION

Despite the availability of web-based and e-health resources, further research is needed to identify how to facilitate greater access and actual use of digital health resources by Latinos. This is an important effort in order to prevent a widening health equity gap caused by a lack of access and use of digital health resources.

Egocentric networks and physical activity outcomes in Latinas

OBJECTIVE

Despite data linking the social environment to physical inactivity in Latinas, research on social network predictors of physical activity (PA) is limited. This study examined social network predictors of PA change in Latinas.

METHODS

Egocentric network data were collected from 102 adult Latinas (egos) participating in a randomized controlled PA intervention trial for underactive women. Moderate-to-vigorous PA (MVPA) was measured in minutes per week using the 7-Day PA Recall Interview and accelerometers at baseline and 12 months. Analyses characterized social network structure, composition, tie strength, homogeneity, and support for PA and determined the relationship between network characteristics and PA outcomes.

RESULTS

Networks had an average of four social ties (alters). Networks were high in density and transitivity and low in components, indicating high cohesion. Networks were primarily composed of females, Latinos, Spanish-speakers, and family members. Relationship ties were strong as evidenced by close living proximity, in-person contact, high emotional closeness, and long relationship duration. There was high homogeneity in demographics and PA behaviors. Multivariate analyses revealed that network size, familial ties, contact frequency, and ego-alter dissimilarities in age and running but similarities in walking, were associated with increased MVPA. Networks high in support for PA in the form of complimenting ego on exercise, taking over chores to allow ego to exercise, and co-participating with ego in exercise were also associated with greater MVPA.

CONCLUSION

These findings contribute to better understanding interpersonal processes that may influence behavior change in a group with especially low levels of PA.

Web-Based Physical Activity Intervention for Latina Adolescents: Feasibility, Acceptability, and Potential Efficacy of the Niñas Saludables Study

BACKGROUND

Physical activity is markedly low in Latina adolescents, yet few physical activity interventions have been attempted in this population. Web-based interventions can incorporate theory-based components, be appealing to adolescents, and have potential for low-cost dissemination.

OBJECTIVE

This study aimed to assess the feasibility, acceptability, and potential efficacy of a Web-based physical activity intervention for Latina adolescents in a single-arm pilot trial.

METHODS

A total of 21 Latina adolescents (aged 12-18 years) who could read and write in English and were underactive (<90 min/week) participated in a 12-week, theory-informed Web-based physical activity intervention. The intervention website was modified from a previous Web-based intervention for Latina adults. Web content was individually tailored based on the responses to monthly questionnaires. Feasibility was measured by recruitment, retention, and adherence/engagement, and acceptability was measured by satisfaction surveys. Physical activity was measured at baseline and follow-up (12 weeks) using the 7-day physical activity recall (PAR) interview and accelerometers.

RESULTS

Baseline activity as measured by the 7-day PAR and accelerometers was 24.7 (SD 26.11) and 24.8 (SD 38.3) min/week, respectively. At 12 weeks, 19 participants (90%, 19/21) returned. Adherence and engagement with materials were low, but 72% (15/21) of the participants indicated that they were satisfied with the intervention. Activity at 12 weeks increased by 58.8 (SD 11.33) min/week measured by the 7-day PAR (P<.001). Accelerometer-measured activity did not increase. Activities reported at follow-up were more varied than at baseline, including some activities measured poorly by accelerometers (eg, biking and swimming). Participants suggested simplifying the website and incorporating other technologies.

CONCLUSIONS

Good retention and increases in self-reported activity suggest a promising approach to delivering a physical activity intervention to Latina adolescents. Incorporating other technologies, such as smartphone apps, could make the intervention more engaging, acceptable, and effective.
