Systematic Review of Physical Activity Interventions in Hispanic Adults

'I didn't expect to be so close to being diabetic': beliefs of prediabetes and diabetes prevention among Hispanic men at a federally qualified health center

OBJECTIVES

Prediabetes is disproportionately prevalent in Hispanic men in the United States. Weight management, such as through lifestyle interventions, effectively reduces diabetes risk. However, Hispanic men remain underrepresented in existing lifestyle interventions, and their preferences for engaging in preventative behaviors remain unexplored. We aimed to explore the experiences of Hispanic men being diagnosed with prediabetes and the perceived influences on engaging in preventative behaviors and lifestyle change.

DESIGN

This qualitative study conveniently sampled Hispanic men with prediabetes (n = 15) from a Federally Qualified Health Center in New York City. Private semi-structured interviews were audio recorded and explored prediabetes beliefs and perceived influences on engaging in preventative lifestyle change. Transcripts were double-coded using a deductive thematic approach, which revealed 5 major themes consistent with the Health Belief Model.

RESULTS

(1) Perceived Susceptibility and Severity: Despite fearing diabetes, Hispanic men are unsure about their personal risk for developing it. (2) Cues to Action: Receiving a clinical diagnosis and recognizing its potential impact on family members heightens concerns about diabetes risk. (3) Benefits of Lifestyle Change: Small, practical changes in dieting and exercising can make preventing diabetes manageable. (4) Barriers to Lifestyle Change: Restrictive environments and schedules, coupled with some cultural habits, can lead to unhealthy lifestyle choices. (5) Self-Efficacy: Lifestyle change is a matter of personal agency, but additional information can support the right changes.

CONCLUSIONS

Influences potentially unique to Hispanic men in this setting included references to unhealthy foods environments, overwhelming working conditions, carbohydrate-rich cultural staples, and the threat of diabetes to self-perceptions of being head-of-family. These findings provide insight into Hispanic men's perceived barriers to engaging in preventative behaviors and motivators that can potentially facilitate their engagement in diabetes prevention.

Evaluating a Community-Based Walking Program: A Mixed-Methods Assessment of Community Capacity

The Border Coalition for Fitness (BCF) is a university-community-based partnership that aims to improve physical activity rates in El Paso, Texas, via walking challenges. This mixed-methods program evaluation assessed the BCF's efforts to expand the El Paso community's capacity to support physical activity through the walking challenge campaign. Informants were divided between members, which was subdivided into BCF members and team captains, and walking challenge participants. Informants completed demographic and community capacity questionnaires that assessed 3 constructs: leadership (L), resources (R), and ability, and commitment to organizing action (C). Participants for this study were recruited by email through participant and member listservs. Of the 2000 participants with active emails, 102 agreed to participate. Quantitative results (n = 102) revealed high ratings across all constructs; however, BCF members consistently rated each construct higher than team captains (members L: 9.71; R: 9.50; C: 9.36 vs community leadership L: 7.97; R: 7.72; C: 7.59). BCF members (n = 5) and former walking challenge participants (n = 3) completed semistructured interviews. While qualitative results revealed BCF leadership is effective, programming is appropriately resourced, and the BCF does drives sustainable action in the community, there were areas the participants identify as areas that needed improvement. Specifically, participants felt that membership recruitment and retention should be improved, and that membership should include more community members and challenge participants.

Implementation Evaluation of a Parks- and Faith-Based Multilevel Intervention to Promote Physical Activity Among Latinos

BACKGROUND

Latinos in the United States face multiple barriers to engaging in physical activity (PA). We implemented a faith-based multilevel intervention to promote PA in parks for Latino adults, which was partially adapted to a virtual platform during the COVID-19 pandemic, and evaluated it using the Reach, Effectiveness, Adoption, Implementation, and Maintenance framework.

METHODS

We conducted in-depth semistructured interviews (83% in Spanish) with 24 intervention participants (75% women) participating in a cluster randomized controlled trial in 2019-2022 that linked 6 churches (3 intervention, 3 control) with parks in East Los Angeles, CA. The intervention included in-person, park-based fitness classes, which were adapted to Facebook during the pandemic; PA motivational text messages; and other activities. Interviews assessed Reach (participation), Effectiveness (perceived impacts), Implementation (participation barriers/facilitators), and Maintenance (plans for sustaining PA), as well as perceived pandemic impacts.

RESULTS

About 80% of interviewees participated in ≥1 park class and 67% in ≥1 virtual class (Reach). Interviewees perceived positive intervention impacts across multiple health and well-being domains (Effectiveness) despite perceived negative pandemic impacts; several facilitators to participation (personal, social, program) and few barriers (personal, virtual, environmental; Implementation); and plans for maintaining PA (eg, revisiting intervention text messages and video recordings; Maintenance).

CONCLUSIONS

Findings support the utility of Reach, Effectiveness, Adoption, Implementation, and Maintenance to understand the broad impacts of a faith-based PA intervention. Findings point to the adaptability and robustness of the intervention during a public health crisis. Overall, findings may help inform the translation of the intervention to other communities to advance health equity.

Identifying Factors That Influence Physical Activity and Healthy Aging Among Older Latino Adults

BACKGROUND

For older Latinos, some benefits of leisure-time physical activity (LTPA) include enhanced cognitive functioning, decreased loneliness, and reduced premature mortality. Despite LTPA benefits, adults ≥50 years are one of the most inactive age groups in the United States.

METHODS

This qualitative study aimed to add to the limited evidence of LTPA in older Latino adults by exploring the barriers and facilitators for fitness class uptake and park use. Guided by a Social-Ecological Model of Health and Social Determinants of Health theoretical and a phenomenological research design, qualitative research data were collected via 27 personal interviews with Latino adults using a semistructured interview guide. Participants were recruited using purposive sampling strategies in collaboration with community partners. Bicultural data collectors conducted the semistructured interviews over Zoom. Thematic analysis was performed using Dedoose, following an inductive and deductive approach.

RESULTS

The main barriers to fitness class attendance and park use were family and/or work commitments, perceived safety, and perceived discrimination. Conversely, the critical facilitators for participation were socialization into a group, social connectedness with group members, fitness instructor characteristics, and exercise history.

CONCLUSIONS

Findings from this study hold important implications for the design of fitness programming and park-based recreation, including the need to increase the cultural diversity of recreation staff and culturally relevant programming. Future research is needed on time poverty related to family/work commitments and whether discriminatory practices at fitness centers, like ageism and race/ethnicity, influence physical activity behavior.

Body image and physical activity in Latinas

Women with negative body image engage in less physical activity. The purpose of this study is to examine the relationship between body image and physical activity in Latinas participating in a lifestyle program. Participants (age 43.8 ± 10.1 years and BMI 30.4 ± 5.2 kg/m2) were enrolled in a 12-month culturally and linguistically adapted, individually tailored, intervention focused on increasing moderate-to-vigorous intensity physical activity (MVPA). Longitudinal assessments were conducted on body image dissatisfaction (BID) using the Figure Rating Scale, MVPA using the 7-day PAR interview, and objectively measured body weight. Pre-intervention BID did not significantly predict MVPA change. Participants experienced considerable reduction in BID. Greater MVPA engagement and weight loss were independently related to BID reduction. Acculturation did not moderate these relationships. Body image improved in Latinas participating in a cognitive and behavioral physical activity intervention regardless of weight loss and acculturation level.

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.

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.

A Study of Immigrant Latinas Perspectives of Caring for their Diabetes

Hispanic-Americans are disproportionately affected by type 2 diabetes compared to non-Hispanic Whites. Five million adult Hispanic Americans are estimated to have been diagnosed with T2D. Among US Hispanics, Mexicans have the highest rate (14.4%) of diabetes. Further, Hispanics are also twice as likely as non-Hispanics Whites to die from diabetes, making it the fifth leading cause of their death and a serious health problem in Hispanic communities. Yet, little is understood of what rural immigrant Latinas do to care for their diabetes health. In-depth interviews (3 focus groups) and thematic analysis found 16 Latinas had T2D on average for 9 years; all emigrated to the USA from Mexico, lived in the USA for an average of 27 years, and worked (60%). Within the domain of "What do you do to take care of your health?" Latinas desired to adhere to exercise, controlled diet, and medications, but perceived a powerful barrier to a healthy life was the American lifestyle that included long work days, more money to purchase unhealthy foods and a desire for them, and a lack of time for other forms of exercise. Despite the Latina participants' years of experience about living with T2D in the US, they still struggled to adhere to healthy behaviors. Future research should address the longer time Hispanic immigrants live in the US with the more at-risk they become for diminished health.

Mexican and Puerto Rican Men's Preferences Regarding a Healthy Eating, Physical Activity and Body Image Intervention

This study examined the logistical, practical, and cultural preferences of Latinos regarding the design of a healthy eating, physical activity, and body image intervention. Puerto Rican and Mexican men (n = 203) completed an interview as part of an NIH-funded study. Overall, 66.5% preferred the intervention to be in Spanish only or both Spanish and English; 88.67% said it was moderately, very or extremely important for the intervention leader to be bilingual; and 66.01% considered it moderately to extremely important for the leader to be Hispanic or Latino. Most participants (83.74%) reported they would be willing to attend an intervention that met twice per week and 74.38% said they would be willing to attend an intervention that met for 1.5 to 2 h, twice weekly. Overall, the majority said they would be moderately to extremely interested in attending an exercise program if it consisted of aerobics with Latin or salsa movements (74.88%) and if it consisted of aerobics with Latin or salsa music (70.44%). Some participants were moderately to extremely interested in attending an intervention if it included dichos (Latino sayings) (65.02%) and cuentos (folktales or stories) (69.46%). The findings have implications for lifestyle and body image interventions aimed at preventing cardiometabolic diseases.

Perceptions of health and illness among older Hispanic adults

BACKGROUND

Understanding perceptions of health and illness among older Hispanic adults is vital for nurses when designing effective health promotion programs.

PURPOSE

The purpose of this study was to explore the perceptions of health and illness and how health was maintained during times of illness.

METHOD

This inductive qualitative descriptive study used a single focus group with interviews over three sessions. All eight members of the focus group were Spanish-speaking, older adults living in the community. Immersion/crystallization and editing analytic styles were used to analyze the data.

RESULTS

Participants were parishioners at a local church and knew each other from participating in community events. Perceptions of health mainly focused on both the absence of illness and physical limitations. Maintaining health included a healthy lifestyle and being physically active; however, food was central to maintaining health. Perceptions of illness were described as "feelings of sickness" such as sadness and worry. Dealing with illness was equated with physical limitations, with strategies suggested, including going to the doctor, preparing natural and folk remedies, spirituality, and support from family and friends.

CONCLUSION

Nurses have an important role in assessing the health management strategies of older Hispanic adults and need to incorporate the older adults' understanding of health and illness into their plan of care.

Engagement in Physical Activity Improves after Participation in Pasos Para Prevenir Cancer-An Obesity-Related Cancer Prevention Program in El Paso, Texas

BACKGROUND

This present study experimentally evaluated the Pasos Para Prevenir Cancer (PPPC) program to determine whether participation was associated with improved physical activity engagement. Evidence suggests that obesity prevention programs improve physical activity (PA) engagement and lead to healthier weights, which substantially impacts cancer and cardiometabolic disease risk. There is a shortage of knowledge on the effectiveness of programs tailored to populations along the U.S.-Mexico border.

METHODS

We collected demographic, nutrition, and physical activity data at baseline, 6 months, and 12 months using the Research Electronic Data Capture (REDCap) for 209 participants. We analyzed the average metabolic equivalents (METS) per week for all physical activity levels and types and the achievement of the recommended METS per week to determine the demographic characteristics most associated with a change between baseline, 6 months, and 12 months.

RESULTS

Light activity was the most common activity at all three points, and it slightly increased at 6 months in work settings. Subjects conducted moderate physical activity primarily at home and work, and moderate physical activity increased more compared to vigorous physical activity.

CONCLUSIONS

Intervention tailoring might improve PA engagement in Mexican Americans residing on the U.S.-Mexico border; however, larger studies that are more diverse are required.

Informing the Physical Activity Evaluation Framework: A Scoping Review of Reviews

OBJECTIVE

Robust program evaluations can identify effective promotion strategies. This scoping review aimed to analyze review articles (including systematic reviews, meta-analysis, meta-synthesis, scoping review, narrative review, rapid review, critical review, and integrative reviews) to systematically map and describe physical activity program evaluations published between January 2014 and July 2020 to summarize key characteristics of the published literature and suggest opportunities to strengthen current evaluations.

DATA SOURCE

We conducted a systematic search of the following databases: Medline, Scopus, Sportdiscus, Eric, PsycInfo, and CINAHL.

INCLUSION/EXCLUSION CRITERIA

Abstracts were screened for inclusion based on the following criteria: review article, English language, human subjects, primary prevention focus, physical activity evaluation, and evaluations conducted in North America.

EXTRACTION

Our initial search yielded 3193 articles; 211 review articles met the inclusion criteria.

SYNTHESIS

We describe review characteristics, evaluation measures, and "good practice characteristics" to inform evaluation strategies.

RESULTS

Many reviews (72%) did not assess or describe the use of an evaluation framework or theory in the primary articles that they reviewed. Among those that did, there was significant variability in terminology making comparisons difficult. Process indicators were more common than outcome indicators (63.5% vs 46.0%). There is a lack of attention to participant characteristics with 29.4% capturing participant characteristics such as race, income, and neighborhood. Negative consequences from program participation and program efficiency were infrequently considered (9.3% and 13.7%).

CONCLUSION

Contextual factors, negative outcomes, the use of evaluation frameworks, and measures of program sustainability would strengthen evaluations and provide an evidence-base for physical activity programming, policy, and funding.

Walking Engagement in Mexican Americans Who Participated in a Community-Wide Step Challenge in El Paso, TX

In the United States, the Latinx population has the highest prevalence of physical inactivity compared with other ethnicities. Research shows that work-based physical activity interventions have been widely implemented in the non-Latinx population and effectively increase physical activity in the non-Latinx population. In an effort to improve physical activity and reduce obesity among the Latinx population, we conducted 10,000 Steps for 100 Days, an employer-based walking challenge campaign, to increase walking engagement among Latinx employees located in El Paso, Texas. Participants reported their number of steps using a pedometer or smartphone. Step counts were collected at baseline, 2 weeks post challenge, and 6 months post challenge. Screenshots of the tracking device were uploaded to an online tracker. Regression analysis was conducted to identify covariates associated with baseline and 2-week and 6-month average daily steps. Generalized estimating equations (GEE) were performed to predict steps over time by demographic characteristics. Participation in the 10,000 Steps for 100 Days walking challenge was associated with a sustained increase in average daily steps. Participants with less than 7000 steps per day demonstrated the greatest increase in average daily steps (921 steps at 2 weeks; 1002.4 steps at 6 months). Demographic characteristics were not significant predictors of average steps, except that married participants had higher average steps. Participants with 10,000 or more daily steps had a 51% (p = 0.031) higher chance of having a professional occupation than a non-professional one compared to those with 7000 or fewer daily steps. We provided initial evidence that the walking challenge is an effective approach for improving physical activity in the Latinx population.

Looking for Crumbs in the Obesity Forest: Anti-obesity Interventions and Obesity-Associated Cardiometabolic Traits in the Mexican Population. History and Systematic Review With Meta-Analyses

Mexicans and Mexican Americans share culture, genetic background, and predisposition for chronic complications associated with obesity and diabetes making imperative efficacious treatments and prevention. Obesity has been treated for centuries focused-on weight loss while other treatments on associated conditions like gout, diabetes (T2D), and hypertriglyceridemia. To date, there is no systematic review that synthesizes the origin of obesity clinics in Mexico and the efforts to investigate treatments for obesity tested by randomized clinical trials (RCT). We conducted systematic searches in Pubmed, Scopus, and Web of Science to retrieve anti-obesity RCT through 2019 and without an inferior temporal limit. The systematic review included RCT of anti-obesity treatments in the Mexican adult population, covering alternative medicine, pharmacological, nutritional, behavioral, and surgical interventions reporting metabolism-associated traits such as BMI, weight, waist circumference, triglycerides, glucose, among others. Only the studies with at least 3 months of treatment were included in the meta-analyses in order to reduce placebo effects. We found 634 entries, after removal of duplicates and screening the studies based on eligibility criteria, we analyzed 43 national, and 2 multinational-collaborative studies. Most of the national studies had small sample sizes, and the implemented strategies do not have replications in the population. The nutrition/behavioral interventions were difficult to blind, and most studies have medium-to-high risk of bias. Nutritional/behavioral interventions and medications showed effects on BMI, waist circumference, and blood pressure. Simple measures like pure water instead of sweet beverages decrease triglycerides and systolic blood pressure. Dark chocolate showed the highest effect for BMI and high blood pressure, and treatment with insulin increased weight in those with T2D. The study of obesity in Mexico has been on-going for more than four decades, the interest on RCT just increased until this millennium, but with small sample sizes and lack of replication. The interventions affect different cardiometabolic associated traits, which should be analyzed in detail in the population living near the Mexico-U.S. border; therefore, bi-national collaboration is desirable to disentangle the cultural effects on this population's treatment response.

Observed physical activity among Latinx and White men and women on a new urban trail

OBJECTIVE

Despite efforts to increase physical activity through new green space infrastructure such as trails, disparities in physical activity may persist. The current study compared observed vigorous physical activity (VPA) engagement among White and Latinx men and women on a new urban trail, and whether engagement varied over time.

DESIGN, SAMPLE, AND MEASURES

We used a modified System for Observing Play and Recreation in Communities (SOPARC) methodology to determine observed race/ethnicity, gender, and physical activity level of trail users (n = 15,109).

RESULTS

Logistic regression analyses revealed the odds of engaging in VPA were lower for Latina women than all other population subgroups (vs. White men: OR 0.19, CI 0.17-0.22; vs. White women: OR 0.48, CI 0.42-0.54, vs. Latino men: OR 0.23, CI 0.19-0.26). VPA engagement by White and Latina women increased across the study years (OR 1.31, CI 1.17-1.46; OR 1.36, CI 1.08-1.71, respectively) but did not differ significantly by year for White and Latino men.

CONCLUSION

Future efforts to address racial/ethnic-gender disparities in VPA should take an intersectional approach to ensure that the needs of the most vulnerable population subgroups are properly accounted for.

Weight Loss Interventions for Hispanic Women in the United States: A Systematic Review

Background

Obesity rates in Hispanic women residing in the United States (U.S.) are disproportionately high, increasing the risk of obesity-related disease and mortality. The effectiveness of interventions targeting weight loss in this population remains largely unknown.

Purpose

The purpose of this review was to systematically evaluate the evidence related to the effectiveness of weight loss interventions conducted among U.S. Hispanic women and provide guidance for future research.

Methods

Bibliographic databases (n = 10, from each database's inception to July 2, 2019) were searched using the PRISMA guidelines for systematic reviews. Randomized controlled trials (RCTs) and quasi-experimental studies with weight change outcomes were included. Results were described in a narrative synthesis.

Results

5,423 articles were assessed for eligibility based on inclusion criteria; 15 studies were included in the final review. Nine trials were RCTs and six were quasi-experimental studies; all but six were pilot studies. Most studies recruited overweight or obese women with no existing medical conditions and did not follow participants beyond the intervention. All trials were delivered in-person. Intervention strategies and content and weight change outcomes were highly variable.

Conclusions

RCTs with statistically powered sample sizes are needed to robustly test the effects of weight loss interventions in this population.

Forming Habits, Overcoming Obstacles, and Setting Realistic Goals: A Qualitative Study of Physical Activity Maintenance Among Latinas

BACKGROUND

The impact of physical activity interventions for Latina women can be enhanced by identifying and implementing strategies to achieve long-term physical activity maintenance. Physical activity promotion research has mainly focused on physical activity initiation and we know little regarding individual, interpersonal, or environmental factors that influence maintenance of physical activity. This study aimed to qualitatively explore and understand factors associated with maintenance and non-maintenance of physical activity among Latinas.

METHODS

Semi-structured individual interviews were conducted with 21 Latinas who increased their physical activity as a result of an intervention, and who completed a 3-month maintenance period without contact from research staff. Data were analyzed using thematic analysis.

RESULTS

Important facilitators of physical activity maintenance described by participants included having made physical activity a habit; the ability to proactively overcome obstacles to engaging in physical activity, and satisfaction with outcomes obtained from engaging in physical activity. Additional facilitators mentioned by both maintainers and non-maintainers included having motivation, social support, and opportunities to be active. Both maintainers and non-maintainers reported high self-efficacy for PA maintenance in the future.

CONCLUSIONS

Guiding intervention participants to form habits and to set realistic expectations could help them to independently continue engaging in physical activity upon completion of physical activity interventions. Teaching them skills to proactively overcome obstacles may also be important for physical activity maintenance.

State of the Nation's Cardiovascular Health and Targeting Health Equity in the United States: A Narrative Review

Importance

Cardiovascular disease is the leading cause of death in the US. The burden of cardiovascular disease morbidity and mortality disproportionately affects racial/ethnic minority groups, who now compose almost 40% of the US population in aggregate. As part of the 2010 American Heart Association (AHA) Strategic Impact Goal, the AHA established 7 cardiovascular health (CVH) metrics (also known as Life's Simple 7) with the goal to improve the CVH of all individuals in the US by 20% by 2020. National estimates of CVH are important to track and monitor at the population level but may mask important differences across and within racial/ethnic minority groups. It is critical to understand how CVH may differ between racial/ethnic minority groups and consider how these differences in CVH may contribute to disparities in cardiovascular disease burden and overall longevity.

Observations

This narrative review summarizes the available literature on individual CVH metrics and composite CVH scores across different race/ethnic minority groups (specifically Hispanic/Latino, Asian, and non-Hispanic Black individuals) in the US. Disparities in CVH persist among racial/ethnic groups, but key gaps in knowledge exist, in part, owing to underrepresentation of these racial/ethnic groups in research or misrepresentation of CVH because of aggregation of race/ethnicity subgroups. A comprehensive, multilevel approach is needed to target health equity and should include (1) access to high-quality health care, (2) community-engaged approaches to adapt disruptive health care delivery innovations, (3) equitable economic investment in the social and built environment, and (4) increasing funding for research in racial/ethnic minority populations.

Conclusions and Relevance

Significant differences in CVH exist within racial/ethnic groups. Given the rapid growth of diverse, minority populations in the US, focused investigation is needed to identify strategies to optimize CVH. Opportunities exist to address inequities in CVH and to successfully achieve both the interim (AHA 2024) and longer-term (AHA 2030) Impact Goals in the coming years.

A scoping review of physical activity interventions for older adults

BACKGROUND

To inform implementation and future research, this scoping review investigates the volume of evidence for physical activity interventions among adults aged 60+. Our research questions are: (1) what is the evidence regarding interventions designed to increase total physical activity in adults aged 60+ years, in accordance with three of the four strategic objectives of GAPPA (active societies, active environments, active people); (2) what is the current evidence regarding the effectiveness of physical activity programmes and services designed for older adults?; and (3) What are the evidence gaps requiring further research?

METHODS

We searched PEDro, MEDLINE, CINAHL and Cochrane from 1 January 2010 to 1 November 2020 for systematic reviews and meta-analyses of physical activity interventions in adults aged 60+. We identified interventions designed to: (1) increase physical activity; and (2) deliver physical activity programmes and services in home, community or outpatient settings. We extracted and coded data from eligible reviews according to our proposed framework informed by TIDieR, Prevention of Falls Network Europe (PROFANE), and WHO's International Classification of Functioning, Disability and Health (ICF). We classified the overall findings as positive, negative or inconclusive.

RESULTS

We identified 39 reviews of interventions to increase physical activity and 342 reviews of programmes/services for older adults. Interventions were predominantly structured exercise programmes, including balance strength/resistance training, and physical recreation, such as yoga and tai chi. There were few reviews of health promotion/coaching and health professional education/referral, and none of sport, workplace, sociocultural or environmental interventions. Fewer reported outcomes of total physical activity, social participation and quality of life/well-being. We noted insufficient coverage in diverse and disadvantaged samples and low-middle income countries.

CONCLUSIONS

There is a modest but growing volume of evidence regarding interventions designed to increase total physical activity in older adults, although more interventional studies with long term follow-up are needed, particularly for GAPPA 1. Active Societies and GAPPA 2. Active Environments. By comparison, there is abundant evidence for GAPPA 3. specific programmes and services, but coverage of sport and workplace interventions, and diverse samples and settings is lacking. Comprehensive reviews of individual studies are now needed as well as research targeting neglected outcomes, populations and settings.

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.

An ORBIT Phase 1: Design study of a citywide employer-based walking challenges in a predominantly Mexican American metropolitan area

Most Mexican-Americans do not meet current physical activity recommendations. This paper uses the ORBIT model of obesity intervention development as a framework to outline the process of establishing three employer-based walking challenges in El Paso, Texas, a predominantly Mexican American community. The walking challenges were planned and implemented through the Border Coalition for Fitness and participating partnering organizations. Over 2000 participants and several employers took part in the walking challenges. Results from this ORBIT Phase 1 design intervention suggest that walking challenges are a feasible approach to increase physical activity in Mexican-Americans.

Weight loss interventions for Hispanic women in the USA: a protocol for a systematic review

BACKGROUND

In the U.S., Hispanic women experience a disproportionate rate of obesity and obesity-related chronic diseases. At the same time, Hispanic women remain considerably underrepresented in behavioral weight loss interventions. The purpose of this review is to systematically evaluate the evidence related to the effectiveness of weight loss interventions among Hispanic women in the U.S. This review will identify elements of successful weight loss interventions as well as areas for future research.

METHODS/DESIGN

The following databases will be searched to identify all relevant articles (from inception onwards): PubMed, Embase, Scopus, Web of Science (Science Citation Index and Social Sciences Citation Index), PsycINFO, CINAHL, Chicano Database, SPORTDiscus, CAB Abstracts, and Google Scholar. We will include randomized controlled trials and quasi-experimental studies of adult women (> 18 years) from Hispanic/Latino background living in the United States. Eligible interventions will target weight-related behaviors (including diet, physical activity, behavior modification and/or their combinations). The review's primary outcome will be weight change (expressed as change in lbs/kg or body mass index (BMI) (kg/m2)). Three reviewers will independently screen and select data and two will extract data. The methodological quality (or risk of bias) of individual studies will be appraised using the Effective Public Health Practice Project Quality Assessment Tool. A narrative synthesis will describe quality and content of the evidence.

DISCUSSION

The aim of this systematic review is to critically examine existing weight loss interventions for Hispanic women in the U.S. and provide quality evidence for the effectiveness of these interventions on weight loss. Further, this review seeks to identify characteristics of effective interventions and suggest future directions for research efforts targeting weight loss in this population. This review will inform the development of future weight loss interventions for this population.
