Antenatal depressive symptoms and adverse birth outcomes in healthy start participants: The modifying role of utilization of mental health services

OBJECTIVE

We examined the association between antenatal depressive symptoms and adverse birth outcomes in Midland Healthy Start (MHS) participants and determined whether receiving mental health services reduced the odds of adverse outcomes among those with elevated antenatal depressive symptoms.

METHOD

Data from a retrospective cohort of participants (N = 1,733) served by the MHS in South Carolina (2010-2019) were linked with their birth certificates. A score of ≥16 on the Center for Epidemiologic Studies Depression Scale was defined as elevated antenatal depressive symptoms. Services provided by MHS were categorized into: (1) receiving mental health services, (2) receiving other services, and (3) not receiving any services. Adverse birth outcomes included preterm birth, low birth weight, and small for gestational age.

RESULTS

Around 31 % had elevated antenatal depressive symptoms. The prevalences of preterm birth, low birthweight, and small for gestational age were 9.5 %, 9.1 %, and 14.6 %, respectively. No significant associations were observed between elevated depressive symptoms and adverse outcomes. Among women with elevated antenatal depressive symptoms, the odds for small for gestational age were lower in those who received mental health services (AOR 0.33, 95 % CI 0.15-0.72) or other services (AOR 0.34, 95 % CI 0.16-0.74) compared to those who did not receive any services. The odds for low birth weight (AOR 0.34, 95 % CI 0.13-0.93) were also lower in those who received mental health services.

CONCLUSIONS

Receiving screening and referral services for antenatal depression reduced the risks of having small for gestational age or low birth weight babies among MHS participants.

Differences in dietary acceptability, restraint, disinhibition, and hunger among African American participants randomized to either a vegan or omnivorous soul food diet

The Nutritious Eating with Soul study was a 24-month, randomized behavioral nutrition intervention among African American adults. This present study, which is a secondary analysis of the NEW Soul study, examined changes in dietary acceptability, restraint, disinhibition, and hunger. Participants (n = 159; 79% female, 74% with ≥ college degree, mean age 48.4 y) were randomized to either a soul food vegan (n = 77) or soul food omnivorous (n = 82) diet and participated in a two-year behavioral nutrition intervention. Questionnaires assessing dietary acceptability (Food Acceptability Questionnaire; FAQ) and dietary restraint, disinhibition, and hunger (Three-Factor Eating Questionnaire; TFEQ) were completed at baseline, 3, 6, 12, and 24 months. Mixed models were specified with main effects (group and time) and interaction effects (group by time) to estimate mean differences in FAQ and TFEQ scores using intent-to-treat analysis. After adjusting for employment, education, food security status, sex, and age, there were no differences in any of the FAQ items, total FAQ score, dietary restraint, disinhibition, and hunger at any timepoint except for one item of the FAQ at 12 months. Participants in the vegan group reported a greater increase in satisfaction after eating a meal than the omnivorous group (mean difference 0.80 ± 0.32, 95% CI 0.18, 1.42; P = 0.01). This is one of the first studies to examine differences in dietary acceptability, hunger, and other eating factors among African American adults randomized to either a vegan or omnivorous soul food diet. The findings highlight that plant-based eating styles are equally acceptable to omnivorous eating patterns and have similar changes in hunger, restraint, and disinhibition. These results suggest that plant-based eating styles can be an acceptable dietary pattern to recommend for cardiovascular disease prevention and may result in greater post-meal satisfaction.

Prepandemic Feasibility of Tele-Exercise as an Alternative Delivery Mode for an Evidence-Based, Tai Ji Quan Fall-Prevention Intervention for Older Adults

There is a critical need for fall-prevention interventions to reach medically underserved, hard-to-reach, rural older adults. The evidence-based Tai Ji Quan: Moving for Better Balance (TJQMBB) program reduces falls in older adults. This pre-COVID-19 pandemic study assessed the feasibility and impact of a 16-week tele-TJQMBB intervention in older adults. Instructors led six tele-TJQMBB classes via Zoom for 52 older adults (mean age ± SD 68.5 ± 7.7 years) at one academic and four community sites. Nearly all (97%) planned sessions were delivered. Average attendance was 61%. There were no adverse events. Fidelity was fair to good (mean 67%). Forty-one percent of sessions experienced technical disruptions. Participants improved their gait speed, balance, lower-extremity strength, and body mass index. Tele-TJQMBB was feasible with a positive impact on outcomes. This study was the first step toward establishing an additional delivery mode that could potentially expand TJQMBB's reach and maintenance.

Community Health Worker Implementation and Cost Analysis of a Plant-Based Nutrition Program

OBJECTIVE

This study describes program implementation through a research-restaurant partnership and assesses participant satisfaction, program costs, and percent body weight changes.

METHODS

Participants (n = 60) in a virtual synchronous (n = 43) or virtual asynchronous (n = 17) 12-week plant-based nutrition program received restaurant vouchers. Class satisfaction data were collected weekly. Assessments were completed at baseline, 3 months, and 9 months, along with interviews (n = 13) between 3 and 9 months. The costing approach estimated costs per participant. Interviews were coded using a content analysis and constant comparative method.

RESULTS

Participants rated the intervention favorably. Program costs were $198.63/participant, and participants' willingness to pay postintervention was $101.50 ± $63.90. Participants shared satisfaction with course content, the restaurant partnership, and suggestions for future delivery. No changes in participants' percent body weight were observed between 3 and 9 months (P = 0.98), indicating maintenance of 3-month weight loss.

CONCLUSIONS AND IMPLICATIONS

A research-restaurant partnership successfully implemented a nutrition program and generated positive feedback. With the lifting of coronavirus disease 2019 pandemic restrictions, future research can now test alternative implementation methods (in person vs online) in other restaurants.

Barriers and Facilitators to 24-Month Maintenance of the Faith, Activity, and Nutrition Program in the U.S

Little is known about the barriers and facilitators to organizational maintenance of faith-based health promotion programs. This study used qualitative data (collected from 2016-2019) from pastors (n = 81) and program coordinators (n = 103) to identify barriers and facilitators to 24-month maintenance of a faith-based physical activity (PA) and healthy eating (HE) intervention in South Carolina. Barriers differed for PA versus HE: resistance to change impeded HE while church characteristics tended to impede PA. Similar themes emerged for PA and HE facilitators: healthy opportunities, church communication, and consistency. Future research should build upon this study to tailor faith-based health promotion programs for long-term sustainability.

Achievement of Target Gain Larger than Unity in an Inertial Fusion Experiment

On December 5, 2022, an indirect drive fusion implosion on the National Ignition Facility (NIF) achieved a target gain G_{target} of 1.5. This is the first laboratory demonstration of exceeding "scientific breakeven" (or G_{target}>1) where 2.05 MJ of 351 nm laser light produced 3.1 MJ of total fusion yield, a result which significantly exceeds the Lawson criterion for fusion ignition as reported in a previous NIF implosion [H. Abu-Shawareb et al. (Indirect Drive ICF Collaboration), Phys. Rev. Lett. 129, 075001 (2022)PRLTAO0031-900710.1103/PhysRevLett.129.075001]. This achievement is the culmination of more than five decades of research and gives proof that laboratory fusion, based on fundamental physics principles, is possible. This Letter reports on the target, laser, design, and experimental advancements that led to this result.

Adverse pregnancy outcomes and renal-vascular function in the early years after delivery

Adverse pregnancy outcomes (APOs: hypertensive disorders, gestational diabetes, preterm birth, and placental disorders) are associated with cardiovascular disease risk or blood volume abnormalities. Traditional risk factors might not identify highest risk people in the early years after APO deliveries. Test the hypothesis that vascular function is worse, and plasma volume-regulating renal hormones are lower after delivery in people who did versus did not have an APO. Adult participants 6 mo-3 years postdelivery of a singleton infant participated in this cross-sectional study. Exclusion criteria included current smoking, current use of certain medications, and diabetes outside of pregnancy. Differences in measurements between participants with versus without APOs were determined with t tests or Wilcoxon tests. Associations of renal hormones with APO history were assessed with linear regression, adjusted for age, race, body mass index (BMI), and sodium consumption. Of 86 participants, 38 (44%) had an APO history. Those with APOs were more likely to identify as Black and had a higher BMI, 34.0 kg/m2 [interquartile range (IQR), 24.6, 39.3] versus 24.2 kg/m2 [IQR, 21.2, 31.3], P < 0.05. Most brachial and all aortic blood pressures were higher in those with APOs: median aortic blood pressure was 102/74 versus 96/68 mmHg, P ≤ 0.05. There were no differences in arterial stiffness or endothelial function between groups. Aldosterone was lower (54 [IQR, 28-84] vs. 80 [IQR, 39-150] pmol/L) in participants with past APOs. Blood pressures were higher, and aldosterone was lower in participants with past APOs. Associations of aldosterone with APO history persisted after adjustment. Neither renin nor aldosterone were related to vascular function.NEW & NOTEWORTHY Adverse pregnancy outcomes (APOs) are associated with cardiovascular disease (CVD) risk. Traditional CVD risk factors may not fully capture excess CVD risk soon after APOs. Vascular dysfunction and plasma volume irregularities may be detectable. We found people with APOs had worse blood pressures, higher BMI, and lower aldosterone levels versus those without APOs in the early years after delivery. Vascular function was similar between groups. Future research should assess vascular function and renal hormones at multiple timepoints during the perinatal period.

Association Between Physical Activity During Pregnancy and Perinatal Depressive Symptoms in Pregnant Individuals With Overweight and Obesity

INTRODUCTION

Current research on the association between physical activity and perinatal depression is inconclusive. This study examined the association between objectively measured physical activity during pregnancy and perinatal depressive symptoms among individuals with overweight and obesity.

METHODS

Data came from the Health in Pregnancy and Postpartum study (N = 205). Physical activity was measured using the SenseWear Armband at 16 weeks' or fewer and 32 weeks' gestation and categorized into 1) never meeting 2018 physical activity guidelines, 2) meeting the guidelines at one time point, or 3) meeting the guidelines at both time points. Antenatal depressive symptoms were assessed at 32 weeks' gestation, and postpartum depressive symptoms were assessed at 6 and 12 months postpartum using the Edinburgh Postnatal Depression Scale. A score of 10 or higher was defined as probable at least minor depression (hereafter, probable depression).

RESULTS

Nearly one-half of the participants (45.4%) met physical activity guidelines both in early and late pregnancy. Pregnant individuals who met physical activity guidelines at one (adjusted odds ratio, 0.07; 95% confidence interval, 0.01-0.76) or both time points (adjusted odds ratio, 0.08; 95% confidence interval, 0.01-0.69) during pregnancy had lower odds of probable depression at 6 months postpartum than individuals who never met physical activity guidelines during pregnancy. No significant associations were found between prenatal physical activity and probable antenatal or postpartum depression at 12 months.

CONCLUSIONS

Antenatal physical activity was associated with lower odds of probable depression at 6 months after childbirth. Physicians should use evidence-based strategies to encourage pregnant people, especially those who are at risk for postpartum depression, to meet physical activity guidelines.

Recruitment and Retention Strategies for Underrepresented Populations and Adults With Arthritis in Behavioral Interventions: A Scoping Review

OBJECTIVE

To identify strategies used to recruit and retain underrepresented populations and populations with arthritis or fibromyalgia (FM) into behavioral programs targeting exercise, physical activity, or chronic disease self management.

METHODS

Five bibliographic databases were searched for articles published between January 2000 and May 2022. The search focused on strategies and best practices for recruiting and retaining underrepresented populations or populations with arthritis or FM into disease self-management or physical activity/exercise programs. Abstracts and full-text articles were screened for inclusion by 2 independent reviewers, and 2 reviewers extracted data from included articles.

RESULTS

Of the 2,800 articles, a total of 43 publications (31 interventions, 8 reviews, 4 qualitative/descriptive studies) met criteria and were included. The majority of studies focused on physical activity/exercise (n = 36) and targeted African American (n = 17), Hispanic (n = 9), or arthritis populations (n = 7). Recruitment strategies that were frequently used included having race- or community-matched team members, flyers and information sessions in areas frequented by the population, targeted emails/mailings, and word of mouth referrals. Retention strategies used included having race- or community-matched team members, incentives, being flexible, and facilitating attendance. Most studies used multiple recruitment and retention strategies.

CONCLUSION

This scoping review highlights the importance of a multifaceted recruitment and retention plan for underrepresented populations and populations with arthritis or FM in behavioral intervention programs targeting exercise, physical activity, or chronic disease self management. Additional research is needed to better understand the individual effects of different strategies and the costs associated with the various recruitment/retention methods in underrepresented populations and populations with arthritis.

Association of a Lifestyle Intervention with Blood Pressure Trajectories During Pregnancy and Postpartum in Women with Pre-pregnancy Overweight and Obesity

OBJECTIVES

Healthy lifestyle, including healthy diet and physical activity, has been associated with lower blood pressure (BP). We hypothesized that overweight/obese women randomized to a lifestyle intervention beginning in early pregnancy would be less likely to have a higher BP trajectory.

METHODS

The Health in Pregnancy and Postpartum study promoted a healthy lifestyle in pregnant and postpartum women with pre-pregnancy overweight or obesity. BP was measured at study visits at ≤ 16 and 32 weeks of pregnancy and 6 and 12 months postpartum. Latent class trajectories were constructed to identify groups of participants with similar BP patterns throughout the study period. Odds of being assigned to the higher BP trajectories between the intervention and control group were determined with logistic regression, adjusted for age, race, pre-pregnancy BMI, gestational weight gain, smoking during the study period, and household income.

RESULTS

Of the 219 participants enrolled (44.3% Black participants, 55.7% White participants, mean age = 29.7 ± 0.3 years), 112 (51.1%) were randomized to the intervention. Two systolic and diastolic BP trajectory groups were identified (Low-Stable, Moderate-Increasing). Randomization to the lifestyle intervention was not associated with odds of Moderate-Increasing systolic (OR 0.83, 95%CI 0.4, 1.6) or diastolic (OR 0.67, 95%CI 0.3, 1.3) BP trajectory assignment. Those in the Moderate-Increasing BP groups had higher BMI and were more likely to have an adverse pregnancy outcome.

CONCLUSIONS

A lifestyle intervention initiated in early pregnancy to help prevent excessive gestational weight gain was not associated with odds of specific BP patterns through pregnancy and postpartum.

Promoting physical activity via physical therapist following knee replacement: A pilot randomized controlled trial

BACKGROUND

Outpatient physical therapy may be an opportune time to promote aerobic physical activity after knee replacement; however, it is unknown if it is feasible to integrate a physical activity intervention within standard physical therapy.

OBJECTIVE

To examine the feasibility and acceptability of a physical activity intervention delivered within outpatient physical therapy for adults after knee replacement.

METHODS

As part of a cluster randomized trial, adults with knee replacement starting outpatient physical therapy were recruited across four physical therapy sites. Sites were randomized and physical therapists delivered either an enhanced physical activity intervention or a control condition. The enhanced physical activity intervention consisted of standard postoperative physical therapy plus goal setting, problem-solving, and use of motivational interviewing techniques to promote 150 minutes/week of aerobic moderate intensity physical activity. The control group received standard postoperative physical therapy only. Feasibility and acceptability were determined based on recruitment and retention rates at 12 weeks after surgery. Outcomes including objectively measured physical activity, pain, and self-reported function were examined at the baseline postoperative visit and 12 weeks later.

RESULTS

Thirty-three percent of candidates screened were randomized (n = 45) and retention at 12 weeks after surgery was 91% (no difference by condition). Moderate-intensity activity increased, pain decreased, and self-reported function improved, but there were no statistically significant group differences between baseline and 12 weeks.

CONCLUSION

Implementing a physical activity intervention within outpatient physical therapy for adults after knee replacement is feasible; however, in this pilot study, changes were not observed in moderate intensity physical activity as compared to standard postoperative physical therapy. Future studies are needed to explore additional low-cost strategies and the optimal time to promote physical activity after knee replacement.

Falls and Fall-Related Injuries in an Evidence-Based Tai Ji Quan Intervention in Rural West Virginia Churches

Background

This paper identifies the independent predictors of falls in an implementation study of Tai Ji Quan: Moving for Better Balance® (TJQMBB) in older adults in rural West Virginia churches.

Methods

Falls and injuries were identified via calendars, questionnaire, and verbal reports.

Results

Fall predictors were gait speed (OR 0.27; 95% CI 0.08, 0.90); low back pain (OR 8.04; 95% CI 1.71, 37.79); and pain, stiffness, or swelling limiting activity (OR 2.44; 95% CI 1.09, 5.45).

Conclusions

Determining differences between fallers and non-fallers may identify people with different fall risk profiles and ultimately better tailor fall-prevention programming to individual needs.

COVID-19 challenges, responses, and resilience among rural Black women: a study protocol

Despite the aggregated burdens and challenges experienced by rural Black women during the COVID-19 pandemic, many likely also demonstrated strength and resilience to overcome challenges. A mixed methodology and a community-based participatory approach will be used to collect multilevel data on challenges, responses, resilience, and lessons during the pandemic from Black women, community health workers, and community leaders in rural areas in South Carolina (SC). Specifically, the unique circumstances and lived experiences of rural Black women during the COVID-19 pandemic will be documented to understand their needs regarding effective management of social, physical, and mental health challenges through focus group discussions and in-depth interviews with Black women, community health workers, and local community leaders recruited from rural SC communities. Barriers, facilitators, and potential impacts of multilevel resilience development will be identified through a survey administered among rural Black women recruited from 11 rural counties (with one as site for a pilot testing of the questionnaire). A report for public health practice will be developed, including recommended strategies to optimize health systems' emergency preparedness and responses through triangulation of qualitative and quantitative data from multiple sources. Findings in the proposed study will provide valuable references in terms of addressing social determinants of health factor challenges during the pandemic, fostering resilience, and informing evidence-based decision-making for policymakers. The study will contribute to the development of public health emergency preparedness plans, which can promote the resilience of women, their families, and local communities as well as optimize effective preparedness and response of health systems for rural Black women and their families during infectious disease outbreaks and other public health emergencies.

Implementation During a Pandemic: Findings, Successes, and Lessons Learned from Community Grantees

Funding communities through mini-grant programs builds community capacity by fostering leadership among community members, developing expertise in implementing evidence-based practices, and increasing trust in partnerships. The South Carolina Cancer Prevention and Control Research Network (SC-CPCRN) implemented the Community Health Intervention Program (CHIP) mini-grants initiative to address cancer-related health disparities among high-risk populations in rural areas of the state. One community-based organization and one faith-based organization were funded during the most recent call for proposals. The organizations implemented National Cancer Institute evidence-based strategies and programs focused on health and cancer screenings and physical activity and promotion of walking trails. Despite the potential for the COVID-19 pandemic to serve as a major barrier to implementation, grantees successfully recruited and engaged community members in evidence-based activities. These initiatives added material benefits to their local communities, including promotion of walking outdoors where it is less likely to contract the virus when socially distanced and provision of COVID-19 testing and vaccines along with other health and cancer screenings. Future mini-grants programs will benefit from learning from current grantees' flexibility in program implementation during a pandemic as well as their intentional approach to modifying program aspects as needed.

NEW Soul in the neighborhood-reach and effectiveness of a dissemination and implementation feasibility study

Dissemination and implementation (D&I) studies of dietary interventions for African Americans are limited. Restaurants may be an innovative setting to deliver dietary interventions. Purpose: Assess weight loss, self-efficacy for healthy eating, diet quality, and quality of life in African Americans in two groups: virtual synchronous and virtual asynchronous. Guided by RE-AIM, the Nutritious Eating with Soul @ Rare Variety Café Feasibility study included nutrition education, accountability partners for support, and cooking demonstrations led by a community health worker and was delivered across two cohorts in a non-randomized design. The intervention was conducted over 12 consecutive weekly classes. Due to the COVID-19 pandemic, intervention delivery was online. African Americans between 18-65 years old with overweight/obesity, not currently following a plant-based diet or taking medications to control diabetes, and living in a southeastern city were recruited. Participants completed in-person weight assessments and online surveys at baseline and post-intervention. Linear mixed models analyzed changes in outcomes and differences in 3-month outcomes between groups. All models controlled for age and sex. Regarding Reach, 199 participants expressed interest, and 60 enrolled. Among the full sample, participants decreased body weight -2.6 ± 0.5 kg (p < .0001) and increased self-efficacy 1.6 ± 0.7 points (p = .03). No differences in 3-month outcomes between groups were observed. This D&I feasibility study successfully recruited participants during the COVID-19 pandemic and produced significant results. The successful online intervention delivery compared to in-person suggests the potential for greater D&I in vegan soul food restaurants. As restrictions are loosened, future studies will test in-person delivery.

Impact of a Large Healthy Start Program on Perinatal Outcomes, South Carolina, 2009-2019

Using linked birth and death certificates for participants served by a Healthy Start program in South Carolina and community controls, we found that the Healthy Start program contributed to significant improvements in prenatal care, breastfeeding initiation, and participation in the Special Supplemental Nutrition Program for Women, Infants, and Children and significant reductions in inadequate weight gain and large-for-gestational-age births. However, Healthy Start participants were more likely to gain excessive weight during pregnancy, and there were no significant differences in perinatal outcomes. (Am J Public Health. Published online ahead of print March 9, 2023:e1-e5. https://doi.org/10.2105/AJPH.2023.307232).

A 12-Week Randomized Intervention Comparing the Healthy US, Mediterranean, and Vegetarian Dietary Patterns of the US Dietary Guidelines for Changes in Body Weight, Hemoglobin A1c, Blood Pressure, and Dietary Quality among African American Adults

BACKGROUND

The US Dietary Guidelines (USDG) form the basis of nutrition guidelines, but the research informing the 3 USDG dietary patterns (Healthy US-Style [H-US], Mediterranean [Med], and vegetarian [Veg]) has been drawn largely from observational studies among White populations.

OBJECTIVES

The Dietary Guidelines 3 Diets study was a 3-arm, 12-wk randomly assigned intervention among African American (AA) adults at risk of type 2 diabetes mellitus that tested the 3 USDG dietary patterns.

METHODS

The AAs (ages 18-65 y, BMI 25-49.9 kg/m2, and BMI was measured in kg/m2) with ≥3 type 2 diabetes mellitus risk factors were recruited. Weight, HbA1c, blood pressure, and dietary quality (healthy eating index [HEI]) were collected at baseline and 12 wk. In addition, participants attended weekly online classes that were designed using material from the USDG/MyPlate. Repeated measures, mixed models with maximum likelihood estimation, and robust computation of standard errors were tested.

RESULTS

Of the 227 participants screened, 63 were eligible (83% female; age 48.0 ± 10.6 y, BMI 35.9 ± 0.8 kg/m2) and randomly assigned to the Healthy US-Style Eating Pattern (H-US) (n = 21, 81% completion), healthy Mediterranean-style eating pattern (Med) (n = 22, 86% completion), or healthy vegetarian eating pattern (Veg) (n = 20, 70% completion) groups. Within-group, but not between groups, weight loss was significant (-2.4 ± 0.7 kg H-US, -2.6 ± 0.7 kg Med, -2.4 ± 0.8 kg Veg; P = 0.97 between group). There was also no significant difference between groups for changes in HbA1c (0.03 ± 0.05% H-US, -0.10 ± 0.05% Med, 0.07 ± 0.06% Veg; P = 0.10), systolic BP (-5.5 ± 2.7 mmHg H-US, -3.2 ± 2.5 mmHg Med, -2.4 ± 2.9 mmHg Veg; P = 0.70), diastolic blood pressure (-5.2 ± 1.8 mmHg H-US, -2.0 ± 1.7 mmHg Med, -3.4 ± 1.9 mmHg Veg; P = 0.41), or HEI (7.1 ± 3.2 H-US, 15.2 ± 3.1 Med, 4.6 ± 3.4 Veg; P = 0.06). Post hoc analyses showed that the Med group had significantly greater improvements in HEI compared to the Veg group (difference = -10.6 ± 4.6; 95% CI: -19.7, -1.4; P = 0.02).

CONCLUSIONS

The present study demonstrates that all 3 USDG dietary patterns lead to significant weight loss among AA adults. However, none of the outcomes were significantly different between groups. This trial was registered at clinicaltrials.gov as NCT04981847.

Effects of positive social comparative feedback on motor sequence learning and performance expectancies

Introduction

Positive social comparative feedback indicates to the learner that they are performing better than others. While this type feedback supports motor skill learning in some tasks, the effect of social comparative feedback on implicit motor sequence learning remains unknown. The aim of this study was to determine the effect of positive social comparative feedback on the learning of and expectancies for a motor sequence task.

Methods

Forty-eight individuals practiced a joystick-based sequence task and were divided into three feedback groups: CONTROL (no performance feedback), RT ONLY (response time only feedback), and RT+POS (response time plus positive social comparison). Participants attended sessions on two consecutive days: Day 1 for repetitive motor practice/skill acquisition and Day 2 for retention testing. Performance related expectancies, like perceived competence, were measured before and after motor practice on Day 1 and at retention on Day 2.

Results

While all groups improved with practice, the CONTROL group showed better overall performance/learning (faster response times) compared with the RT ONLY group. Despite similar response times, the RT+POS showed higher peak velocities than the RT ONLY group. Overall, the RT+POS and CONTROL demonstrated increases in perceived competence while the RT ONLY group did not.

Discussion

The results of this study suggest that feedback content is an important consideration during motor practice sessions since feedback without context (RT ONLY) may be detrimental to motor sequence learning. The results also suggest that, if providing performance related feedback during practice of a skill that relies on implicit sequence learning processes, comparative context may be necessary for enhancing expectancies and supporting.

A process for converting an in-person training to increase church capacity to implement physical activity and healthy eating practices and policies to an online format

The implementation of evidence-based public health programs into practice is critical for improving health, but trainings for organizational change agents are often not scalable. To describe the process of converting a training that targets faith-based organizational capacity development from an in-person to an online format. We engaged in an iterative process to convert the training delivery mode from in-person to online that included assessing stakeholder support, consulting the literature on best practices, seeking a design team, consolidating content, designing engaging lessons, and building an online site. Feedback from end-users and other audiences was incorporated throughout. Pilot participants with characteristics like intended training users were then recruited via community and faith-based partner networks. They rated their agreement with statements about the effectiveness as well as design and functionality of each lesson and the overall training (1 = strongly disagree, 5 = strongly agree) and participated in a structured follow-up interview. Nine pilot participants (representing 9 churches in 7 states; 6 African American, 5 with health ministries) rated the online lessons favorably (all ratings ≥ 4.5). Most (90.4%) perceived the lesson duration to be "just right" and spent 52.5 ± 9.9 minutes/lesson. Participants evaluated the overall training positively (all ratings ≥ 4.7). Lesson content, resources, multimedia, and program ideas were most-liked aspects of lessons, while content, staff responsiveness, discussion board, and pace were most-liked aspects of the overall training in open-ended and interview responses. This paper shares a replicable process for converting training modalities from in-person to online with the goal of increased scalability.

Effect of a Plant-Based vs Omnivorous Soul Food Diet on Weight and Lipid Levels Among African American Adults: A Randomized Clinical Trial

IMPORTANCE

More African American individuals die from cardiovascular disease (CVD) than any other chronic disease condition. Despite this disparity, African American individuals are underrepresented in nutrition and CVD interventions.

OBJECTIVE

To compare the effects of an entirely plant-based (vegan) or low-fat omnivorous (omni) diet on change in body weight and lipids during a 2-year intervention.

DESIGN, SETTING, AND PARTICIPANTS

The Nutritious Eating With Soul (NEW Soul) study was a 2-year, randomized clinical trial conducted in 2 cohorts (2018-2020 and 2019-2021) that took place in a university teaching kitchen in Columbia, South Carolina (before March 2020), and via online videoconference sessions (after March 2020). Participants included African American adults aged 18 to 65 years with overweight or obesity (body mass index of 25.0-49.9) and without type 2 diabetes, uncontrolled thyroid disease, recent weight loss, or pregnancy. Data assessors and statisticians were blinded to study condition. Data analysis was performed from March to June 2022.

INTERVENTIONS

The intervention included weekly nutrition classes for 6 months biweekly classes for 6 months, and monthly classes for 12 months. Dietary interventions either emphasized no animal product intake (vegan) or a low-fat omnivorous diet (omni). Both dietary patterns emphasized soul food cuisine (traditional African American southern foodways).

MAIN OUTCOMES AND MEASURES

Primary outcomes included change in body weight and lipid measures at 12 months.

RESULTS

There were 568 participants who completed an online screening questionnaire; 409 were excluded and 159 were randomized (77 to the vegan group and 82 to the omni group). Of the 159 participants (mean [SD] age, 48.4 [10.6] years; 126 female [79%]) who began the study, the main outcome of body weight was obtained for 121 participants (76%) at 12 months. There were no differences in outcomes between groups, including 12-month changes in weight (mean, -2.39 kg [95% CI, -3.48 to -1.30 kg] for the vegan group vs -2.03 kg [95% CI, -3.07 to -1.00 kg] for the omni group; P = .64), total cholesterol (-1.05 mg/dL [95% CI, -9.60 to 7.50 mg/dL] for the vegan group vs 1.66 mg/dL [95% CI, -7.20 to 10.50 mg/dL] for the omni group; P = .67), or low-density lipoprotein cholesterol (mean, -2.56 mg/dL [95% CI, -9.52 to 4.40 mg/dL] for the vegan group vs -0.79 mg/dL [95% CI, -7.98 to 6.40 mg/dL] for the omni group; P = .73). Weight loss at 12 months among cohort 1, whose weight was assessed in 2019 before the COVID-19 pandemic, was significantly greater than that for cohort 2, whose weight was assessed summer 2020 during COVID-19 (-3.45 kg [95% CI, -4.67 to -2.22 kg] vs -1.24 kg [95% CI, -2.24 to -0.25 kg]; P = .01).

CONCLUSIONS AND RELEVANCE

In this randomized clinical trial examining weight loss and CVD risk factor reduction among African American adults, there were no differences between the groups, and the magnitude of changes overall was small.

Effects of a behavioral intervention on physical activity, diet, and health-related quality of life in pregnant women with elevated weight: results of the HIPP randomized controlled trial

BACKGROUND

Physical activity (PA), diet, and health-related quality of life (HRQOL) are related to maternal and infant health, but interventions to improve these outcomes are needed in diverse pregnant women with elevated weight.

METHODS

Health In Pregnancy and Postpartum (HIPP) was a randomized controlled trial. Women who were pregnant (N=219, 44% African American, 56% white) with overweight or obesity but otherwise healthy were randomized to a behavioral intervention grounded in Social Cognitive Theory (n=112) or to standard care (n=107). The intervention group received an in-depth counseling session, a private Facebook group, and 10 content-based counseling calls with accompanying behavioral podcasts followed by weekly or biweekly counseling calls until delivery. The standard care group received monthly mailings and 10 podcasts focused on healthy pregnancy. PA (SenseWear armband), diet (ASA24), and HRQOL (SF-12) measures were obtained from blinded assessors at baseline (<16 weeks) and late pregnancy (32 weeks). Mixed model repeated measures regression models tested treatment (Group x Time) and within-group effects. We hypothesized that intervention participants would have higher levels of PA, a better-quality diet, and higher HRQOL than standard care participants. Exploratory analyses examined whether changes in outcomes over time differed according to whether participants had recommended, excessive, or inadequate weight gain.

RESULTS

Treatment effects favored intervention participants for vegetable intake (d=0.40, p<0.05) and % whole grains (d=0.60, p<0.01). HRQOL mental component improved in both groups, but less in intervention than standard care participants (d=-0.33, p<0.05). Time effects demonstrated that total PA, steps/day, and HRQOL physical component declined significantly in both groups. Within-group effects showed that diet quality significantly improved in intervention participants. Moderate-intensity PA declined significantly in standard care participants, whereas light-intensity PA declined and sedentary behavior increased significantly in intervention participants. Finally, exploratory analyses showed that total PA and light PA increased whereas sedentary behavior decreased among those meeting guidelines for weight gain, with opposite patterns seen among those with excessive or inadequate weight gain.

CONCLUSIONS

The intervention improved several dietary outcomes but had modest impacts on PA and HRQOL, underscoring the challenge of behavior change during pregnancy.

Developing criteria for research translation decision-making in community settings: a systematic review and thematic analysis informed by the Knowledge to Action Framework and community input

Background

There is a pressing need to translate empirically supported interventions, products, and policies into practice to prevent and control prevalent chronic diseases. According to the Knowledge to Action (K2A) Framework, only those interventions deemed “ready” for translation are likely to be disseminated, adopted, implemented, and ultimately institutionalized. Yet, this pivotal step has not received adequate study. The purpose of this paper was to create a list of criteria that can be used by researchers, in collaboration with community partners, to help evaluate intervention readiness for translation into community and/or organizational settings.

Methods

The identification and selection of criteria involved reviewing the K2A Framework questions from the “decision to translate” stage, conducting a systematic review to identify characteristics important for research translation in community settings, using thematic analysis to select unique research translation decision criteria, and incorporating researcher and community advisory board feedback.

Results

The review identified 46 published articles that described potential criteria to decide if an intervention appears ready for translation into community settings. In total, 17 unique research translation decision criteria were identified. Of the 8 themes from the K2A Framework that were used to inform the thematic analysis, all 8 were included in the final criteria list after research supported their importance for research translation decision-making. Overall, the criteria identified through our review highlighted the importance of an intervention’s public health, cultural, and community relevance. Not only are intervention characteristics (e.g., evidence base, comparative effectiveness, acceptability, adaptability, sustainability, cost) necessary to consider when contemplating introducing an intervention to the “real world,” it is also important to consider characteristics of the target setting and/or population (e.g., presence of supporting structure, support or buy-in, changing sociopolitical landscape).

Conclusions

Our research translation decision criteria provide a holistic list for identifying important barriers and facilitators for research translation that should be considered before introducing an empirically supported intervention into community settings. These criteria can be used for research translation decision-making on the individual and organizational level to ensure resources are not wasted on interventions that cannot be effectively translated in community settings to yield desired outcomes.

The FAN program plan: Creating a healthy church environment for physical activity and healthy eating

Background

Faith, Activity, & Nutrition (FAN) helps churches create a healthier environment for physical activity (PA) and healthy eating (HE) through policy, systems, and environmental changes.

Objective

The purpose of this paper is to describe the implementation, evaluation, and revision of the FAN Program Plan across a two-phase study to help churches create guidelines and policies for PA and HE.

Methods

In Phase 1, church committees attended trainings led by Community Health Advisors (CHA) where they assessed current practices to PA and HE. Committees used the FAN Program Plan to outline an implementation plan to increase opportunities, programs, messages, pastor support, and guidelines/practices for PA and HE. FAN Program Plans were submitted to the research team for review. Findings from Phase 1 plans directed revisions in program materials for Phase 2, where the submission and review processes were repeated.

Results

Review of Phase 1 FAN Program Plans (53/54 churches submitted a Program Plan) revealed that church committees confused guidelines/practices with programs and had trouble differentiating programs for PA and HE from providing opportunities (i.e., building PA/HE into existing events). The CHA training, FAN church committee training, FAN Program Plan, and other documents were revised to use the term "guidelines (policies)" instead of "guidelines/practices." In addition, CHAs facilitated a training section on guidelines (policies) to committees, and a guidelines (policies) section was added in the FAN Program Plan and other program documents. These changes in Phase 2 were helpful for differentiating policies from programs and programs from opportunities in FAN Program Plans (53/115 churches submitted a Program Plan), although some confusion remained.

Conclusions

This study underscored challenges churches may have in setting policies for PA and HE and discusses strategies to address these challenges in future faith-based initiatives.

Influence of implementation strategies on implementation outcomes in a statewide dissemination of Faith, Activity, and Nutrition (FAN)

Faith-based organizations are promising settings for implementation science because they can reach populations bearing a disproportionate burden of chronic disease. This study examined how implementation strategies influenced implementation outcomes in Faith, Activity, and Nutrition (FAN) statewide dissemination. Ninety-three (9%) of 985 invited churches enrolled; 91 (98%) and 83 (89%) completed baseline and 12-month assessments. Community Health Advisors trained and provided phone technical assistance to church committees, led by a FAN coordinator. Church committees were charged with developing plans and installing healthy eating (HE) and physical activity (PA) policies, opportunities, messages and pastor support (implementation outcomes). Structural equation modeling examined how implementation strategies influenced implementation outcomes. Nearly all (99%) FAN coordinators and 60% of pastors attended training, 57% of committees submitted program plans and 51%/54% (HE/PA) of committees met 'every few months'. Statistically significant (P < 0.05) model paths showed positive influences of strategies on implementation outcomes: pastor training on HE and PA pastor support; plan completion on HE and PA messages, PA policies and opportunities as well as FAN committee meetings and committee meetings on HE pastor support, HE policies, PA opportunities and HE and PA messages. This study advances implementation science and provides a model applicable to organizations such as worksites and schools.

Process evaluation methods and results from the Health in Pregnancy and Postpartum (HIPP) randomized controlled trial

Background

Excessive gestational weight gain has increased over time and is resistant to intervention, especially in women living with overweight or obesity. This study described the process evaluation methods and findings from a behavioral lifestyle intervention for African American and white women living with overweight and obesity that spanned pregnancy (≤ 16 weeks gestation) through 6 months postpartum.

Methods

The Health in Pregnancy and Postpartum (HIPP) study tested a theory-based behavioral intervention (vs. standard care) to help women (N = 219; 44% African American, 29.1 ± 4.8 years) living with overweight or obesity meet weight gain guidelines in pregnancy and lose weight in postpartum. Participants completed process evaluation surveys at 32 weeks gestation (n = 183) and 6 months postpartum (n = 168) regarding their perceptions of most and least helpful aspects of the intervention. A database tracked delivery and receipt of intervention components (in-depth counseling session, telephone calls, podcasts). Descriptive statistics are used to report fidelity, dose, and participants’ perceptions. We also tested whether dose of behavioral intervention components was associated with gestational weight gain and 6-month postpartum weight retention with linear regression models controlling for baseline age and gestational weeks, receipt of Medicaid, race, parity, and marital status. A content analysis was used to code and analyze responses to open-ended survey questions.

Results

Over 90% of participants (both groups) would recommend the program to a friend. Implementation fidelity was moderately high and greater in pregnancy than postpartum for all intervention components. Dose received and participants’ ratings of the in-depth counseling session and telephone calls were more favorable than podcasts. The Facebook group was not perceived to be very helpful, likely because of low participant interaction. Although podcasts were created to reinforce call topics, this redundancy was viewed negatively by some. More calls completed and more podcasts downloaded related to lower gestational weight gain (p < .05).

Conclusion

Study findings underscore challenges in engaging this important but busy population, especially during the postpartum period.

P10-02 Barriers to use of the internet as an alternative delivery channel for an evidence-based fall-prevention intervention for older adults

Issue/problem

Physical activity (PA) can prevent falls, a leading cause of death globally. Alternative delivery channels may increase the “reach” of interventions into older adult populations in areas which lack trained instructors. Using technology is one alternative to traditional, face-to-face group classes where instructors and participants are in the same room. We delivered a PA program via the Internet for older adults in rural West Virginia (USA). This alternative could help other countries reach more older adults and reduce falls.

Description of the problem

Tai Ji Quan: Moving for Better Balance® (TJQMBB) is an evidence-based intervention for older adults that reduces falls. Adults, ≥ 55 years, attended free, 1-hour tele-TJQMBB sessions, twice weekly, for 16 weeks at 5 remote community sites (3 urban, 2 rural). Trained instructors (new to TJQMBB) led 6 classes from a classroom for participants at remote sites. Instructors/sites used minicomputer, web camera, microphone, and television(s) for live, 2-way verbal/audio exchange. A CPR-certified person was present with participants. This project identified barriers to implementing tele-TJQMBB. Data on barriers were collected from instructors' class logs and summarized.

Results

Fifty-two adults (81% female, mean age 70) attended 23 (median) of 32 sessions. Barriers that caused session cancelations included: participant vacations/unavailability (n = 7), inclement weather (n = 4), technical issues (n = 2), no CPR person (n = 1), classroom not available (n = 1), site closed for state holiday (n = 1), competing event at site (n = 1), and ill instructor (n = 1). Technical barriers during sessions included interruptions/lack of audio, video freezing, and Wi-Fi/Internet connectivity problems. Two participants did not like videoconferencing.

Lessons

Tele-TJQMBB may be easier to teach with instructors who have already taught the program in-person. Selecting instructors/sites that are comfortable with technology may reduce technological barriers. Some older adults may still prefer face-to-face classes. Most cancelations were due to reasons normally encountered in face-to-face classes. Use of technology added new barriers that will need addressed for future classes.

Main messages

Technology reached older adults in areas with no instructors. We think that this is the first time a live, evidence-based, group PA intervention was delivered using this method which could be a model for reaching older adults globally.

Lawson Criterion for Ignition Exceeded in an Inertial Fusion Experiment

For more than half a century, researchers around the world have been engaged in attempts to achieve fusion ignition as a proof of principle of various fusion concepts. Following the Lawson criterion, an ignited plasma is one where the fusion heating power is high enough to overcome all the physical processes that cool the fusion plasma, creating a positive thermodynamic feedback loop with rapidly increasing temperature. In inertially confined fusion, ignition is a state where the fusion plasma can begin "burn propagation" into surrounding cold fuel, enabling the possibility of high energy gain. While "scientific breakeven" (i.e., unity target gain) has not yet been achieved (here target gain is 0.72, 1.37 MJ of fusion for 1.92 MJ of laser energy), this Letter reports the first controlled fusion experiment, using laser indirect drive, on the National Ignition Facility to produce capsule gain (here 5.8) and reach ignition by nine different formulations of the Lawson criterion.

Experiences of midlife and older African American men living with type 2 diabetes

OBJECTIVE

Type 2 Diabetes Mellitus (T2DM) is a complicated disease that disproportionately affects African American men. Understanding the experiences of African American men living with T2DM is important for developing effective, culturally sensitive interventions. The purpose of this study was to describe how African American men view their T2DM and describe their perspectives on living with and self-managing T2DM.

DESIGN

In-depth semi-structured qualitative interviews were conducted with 22 African American men aged 40-85 years diagnosed with T2DM. Interviews were transcribed and analyzed using NVivo 10 with thematic analysis.

RESULTS

Disbelief, shock, and denial were commonly experienced reactions at initial diagnosis. Many participants defined diabetes using words such as 'sugar' or 'glucose' and reported an awareness of health complications caused by diabetes, such as amputations and diabetic comas. Participants expressed various perspectives and attitudes towards having diabetes, including avoidance/apathy, fatalism, guilt and shame, fear and concern, and self-mastery. The majority of men described efforts to self-manage diabetes via glucose monitoring, changing dietary habits, and exercise. Many participants expressed concern over the financial burden associated with managing diabetes and reported that high costs can hinder a patient's ability to maintain active self-monitoring and deter patients from attending needed doctor's visits. Many participants expressed confidence in their healthcare providers, although a few expressed feelings of distrust and being uninformed. Participants tended to most appreciate physicians who spent time discussing their condition and who made an effort to engage in open patient-provider communication.

CONCLUSION

Living with diabetes can be emotionally, physically, and mentally challenging. Efforts to improve adoption and maintenance of self-management behaviors may benefit from sensitivity to the patient's attitude and perspectives towards diabetes self-management, assistance overcoming the financial burden of managing diabetes, and open patient-provider communication.

Effects of a lifestyle intervention on postpartum weight retention among women with elevated weight

OBJECTIVE

The effectiveness of a pregnancy and postpartum behavioral lifestyle intervention on postpartum weight retention was examined.

METHODS

Pregnant women with overweight and obesity in South Carolina were recruited into a theory-based randomized controlled trial (n = 112 intervention, n = 107 standard care), which was designed to reduce gestational weight gain and postpartum weight retention.

RESULTS

Participants (44% African American, 56% White) had a mean prepregnancy BMI of 32.3 kg/m² and were at 12.6 weeks' gestation at baseline. From prepregnancy to 6 months post partum, intervention participants retained less weight than standard care women (mean difference: -3.6 kg, 95% CI: -5.5 to -1.8). The intervention effect was maintained at 12 months post partum (mean difference: -2.4 kg, 95% CI: -4.3 to -0.5). Intervention women had 2.3 times higher odds of having no weight retention at 6 months post partum versus standard care women (95% CI: 1.2 to 4.4). Intervention participants also had lower odds of retaining ≥5% of their prepregnancy weight after delivery (adjusted odds ratio: 0.3, 95% CI: 0.1 to 0.5 at 6 months; adjusted odds ratio: 0.3, 95% CI: 0.2 to 0.6 at 12 months).

CONCLUSION

This theory-based lifestyle intervention resulted in significantly less weight retention at 6 and 12 months after delivery among pregnant women with overweight and obesity.

"They Eat What They Eat, I Eat What I Eat": Examining the Perspectives and Experiences of African Americans Who Adopt Plant-Based Diets

Adopting a plant-rich or plant-based diet is one of the major recommendations for addressing obesity, overweight, and related health conditions in the United States. Currently, research on African Americans' food choices in the context of plant-based diets is limited. The primary aim of this study was to understand food-related experiences and perceptions of African Americans who were participating in the Nutritious Eating with Soul (NEW Soul) study, a culturally tailored dietary intervention focused on increasing the consumption of plant-based foods. The roles of gender and ethnicity were also examined to identify how eating patterns were chosen or maintained. Twenty-one African American adults in South Carolina, who were randomly assigned to either a vegan diet (n = 11) or a low-fat omnivorous diet (n = 10) in the NEW Soul study, completed one-on-one, qualitative interviews. Emerging themes included awareness, being in control, and identity. The study revealed that access to social support and coping strategies for addressing negative comments about plant-based food choices may be important components to include in future nutrition interventions focused on African Americans.

The Faith, Activity, and Nutrition (FAN) dissemination and implementation study: changes in and maintenance of organizational practices over 24 months in a statewide initiative

BACKGROUND

Few studies have examined the impact of ecological health promotion interventions on organizational practices over time, especially in faith-based settings. This statewide dissemination and implementation study examined change in organizational practices and their predictors across a 24-month period, as well as maintenance of change.

METHODS

Using a pre-post quasi-experimental design, church coordinators from 92 United Methodist Churches in South Carolina (42% predominantly African American congregations) completed surveys at baseline, and immediate, 12-, and 24-months post-training regarding physical activity (PA) and healthy eating (HE) organizational practices consistent with the Faith, Activity, and Nutrition (FAN) program (opportunities, policies, pastor support, messages) and possible predictors. The study was guided by the RE-AIM framework and the Consolidated Framework for Implementation Research (CFIR). Mixed model repeated measures analyses examined change in organizational practices over time. Regression models examined CFIR predictors of 24-month PA and HE organizational practices, controlling for baseline practices. Churches were also classified as maintainers (implemented at 12 and 24 months), non-sustained implementers (implemented at 12 but not 24 months), delayed implementers (implemented at 24 but not 12 months), and low implementers (implemented at neither 12 nor 24 months) for each FAN component.

RESULTS

PA and HE organizational practices increased over time (p < .0001). CFIR domains (and constructs within) of intervention characteristics (adaptability, relative advantage, cost/time), inner setting (relative priority, organizational rewards, readiness, congregant needs), characteristics of the implementer (self-efficacy, perceived benefits), and implementation process (engaging opinion leaders, engaging champions) were important predictors of 24-month PA and HE organizational practices. Over half of churches implementing PA policies, PA messages, HE policies, and HE opportunities at 12 months were maintainers at 24 months, and one-third were maintainers for PA opportunities, HE messages, and PA and HE pastor support. Furthermore, 16% of 12-month non-implementers were delayed implementers at 24 months for PA policies and 31% were delayed implementers for HE policies.

CONCLUSIONS

This study makes important contributions to the faith-based health promotion literature by including a large sample of churches, testing an ecological intervention approach, and assessing organizational practices over a 24-month period. Study findings can guide technical assistance and program adaptations over time.

A Self-Determination Theory Application to Physical Activity in Charity Sports Events

Charity sports events, specifically 5K events, reach large numbers of people and may help promote physical activity (PA). Few studies exist applying Self-Determination Theory (SDT) to participation in these events. This study examined changes in SDT constructs of Autonomy, Competence, and Relatedness satisfaction in participants (n = 207) of charity 5K events and (2) examined relationships among post-event SDT constructs, PA, and intention to complete future events. Participants completed online surveys before and after a charity 5K event using the Psychological Needs Satisfaction in Exercise Scale, Behavioral Regulation in Exercise Questionnaire-2, and International Physical Activity Questionnaire-Short Form. Repeated measures analysis of covariance analyzed the first purpose and regression the second. Competence satisfaction increased ( P = .04) and relatedness satisfaction decreased ( P = .04). Higher post-event relatedness satisfaction was associated with intention to complete future charity 5K events (OR = 1.05, 95% CI: 1.00, 1.11). Higher post-event autonomy, competence, and relatedness satisfaction and intrinsic motivation were associated with greater post-event MET-minutes of PA (all P < .05).Findings may be useful for promoting PA and helping organizations increase participation. Specifically, events facilitating relatedness among participants may lead to repeat participation as these events have opportunities to fulfill SDT outcomes and increase post-event PA.

Recruitment and Retention for the Evaluation of a Healthy Food Initiative in Economically Disadvantaged, Majority African American Communities

Effective recruitment and retention supports equitable participation in research. The aim of this article is to describe recruitment and retention methods among residents of highly disadvantaged, predominantly African American communities in the southeastern United States during the evaluation of a healthy food access initiative. We proposed that active and passive recruitment methods, intensive retention strategies, community outreach and involvement, over-enrollment to anticipate attrition, and applied principles of community participation would achieve the study's recruitment and retention goals. The enrollment goal of 560 was met at 94% (n = 527), and the retention goal of 400 was achieved (n = 408).

Agreement between blood pressure from research study visits versus electronic medical records and associations with hypertensive disorder diagnoses in pregnant women with overweight/obesity

OBJECTIVES

Blood pressure (BP) abstracted from electronic medical records (EMR) is moderately correlated to BP in nonpregnant adults with limited agreement. Little is known about the agreement of research versus EMR BP measured during pregnancy or associations of EMR BP with hypertensive disorder of pregnancy (HDP) diagnoses.

METHODS

BP was measured according to guidelines at in-person research study visits in 214 women with prepregnancy overweight or obesity (44.4% African American, mean age = 29.8 ± 4.8 years) at weeks 16 and 32 of pregnancy. Clinic BP readings that occurred within 1 week of the study visits were abstracted from the EMR. We assessed correlations between sources using Pearson's coefficients; the agreement was evaluated with Bland-Altman plots. We compared differences in the proportion of women with an HDP diagnosis in the EMR between women with versus without a hypertensive EMR BP measurement.

RESULTS

SBP and DBP from study visits and the EMR were modestly moderately correlated at both time points; 0.20 < r < 0.44; P < 0.05 for all. The average mean difference was 10.5 mmHg for SBP and <1 mmHg for DBP in early and 7.3 mmHg for SBP and -1.7 mmHg for DBP in late pregnancy. Women with at least one hypertensive BP reading in the EMR were more likely to have an HDP diagnosis recorded in the EMR; 43.5 versus 3.3%; P < 0.01.

CONCLUSION

EMR SBP was higher but moderately correlated with research quality BP in early and late pregnancy. Women with a hypertensive EMR BP measurement were more likely to have an HDP diagnosis in the EMR.

Predictors of implementation in the Faith, Activity, and Nutrition dissemination and implementation study: application of the Consolidated Framework for Implementation Research (CFIR) in a statewide initiative

Faith-based organizations, with broad reach and trust, are well-positioned to promote health. The purpose of the study was to examine 12-month implementation and its predictors in the statewide Faith, Activity, and Nutrition (FAN) dissemination and implementation (D&I) study. Churches (n = 93; 42% predominantly African American) in the [South Carolina] Conference of the United Methodist Church trained by Community Health Advisors participated in the study. Church FAN coordinators (n = 92) completed implementation surveys regarding opportunities, policies, messages, and pastor support for physical activity (PA) and healthy eating (HE) at baseline and 12 months. FAN coordinators and pastors (n = 93) completed CFIR-based measures at baseline, immediate post-training, and 12 months. Repeated measures ANOVAs tested change in PA and HE implementation composite scores; Cohen's d indicated magnitude of change. Mixed model linear regression tested whether CFIR items predicted 12-month implementation, controlling for baseline implementation. PA (d = 1.42) and HE (d = 2.05) implementation increased significantly over time. PA and HE implementation were significantly greater in predominantly African American (versus White) congregations, and HE implementation was greater in churches with <500 members. FAN coordinators' ratings of the inner setting (networks/communication, culture, tension for change, organizational rewards, readiness, and congregant needs) and implementation process (engaging opinion leaders and champions) domains were most predictive of implementation outcomes. Few pastor ratings related to implementation outcomes. This study identified constructs, guided by CFIR, that may be important for understanding PA and HE implementation in churches. Future studies will need to test them for replication. Greater changes in implementation outcomes among African American churches underscores the potential of promoting health equity through this setting.

Pathways of influences leading to adoption of the Faith, Activity and Nutrition (FAN) program in a statewide initiative

RE-AIM (Reach, effectiveness, Adoption, Implementation, Maintenance) and CFIR (Consolidated Framework for Implementation Research) are complementary frameworks guiding research on dissemination and implementation of evidence-based interventions and factors influencing this process. Faith, Activity, and Nutrition (FAN) is an evidence-based program that increased physical activity and fruit and vegetable intake in faith-based settings. The aims of this adoption study were to quantify state-wide church level adoption rates and congregant reach of FAN in accordance with RE-AIM guidelines, and to explore the association of CFIR-derived constructs of the church inner setting and pastor characteristics with FAN adoption. Church recruitment was documented, and data were collected via telephone-administered surveys from 93 pastors in adopting churches and 60 pastors in non-adopting churches. Qualitative Comparative Analysis (QCA) identified combinations of CFIR-derived church and pastor characteristics sufficient for FAN adoption. As defined by RE-AIM, church-level FAN adoption was 11.7 % and congregant-level reach was 20.0 %. Fourteen pathways to adoption were identified; seven of these featured the presence of a culture of concern for congregant health along with openness to new ideas. Results suggest early assessment of these two CFIR-derived inner setting constructs may help identify faith-based organizations predisposed to undertake a comprehensive, environmental intervention to promote congregant health.

Reducing sedentary time using an innovative mHealth intervention among patients with total knee replacement: Rationale and study protocol

INTRODUCTION

Although knee replacement is effective for improving pain and physical function, subsequent improvements in physical activity typically do not follow. As a result, many patients spend most of their day engaged in sedentary behavior, which may put them at higher risk of experiencing poor function and disability. Intervening on sedentary time, rather than physical activity, may be a more feasible first-step approach for modifying activity-related behaviors in adults who received knee replacement.

OBJECTIVE

The purpose of this study is to examine the use of a mobile health (mHealth) intervention to reduce sedentary time among adults who received a knee replacement at 3 and 6 months after surgery.

METHODS

Patients (n = 92) scheduled for knee replacement will be recruited and at 4 weeks after surgery, they will be randomized to either NEAT!2 or Control. NEAT!2 participants will use the NEAT!2 smartphone app, which provides a vibration and/or audible tone to interrupt prolonged bouts of sitting detected from the smartphone's internal accelerometer, until 3 months after surgery. NEAT!2 participants will receive biweekly coaching calls between 4 and 12 weeks after surgery. Control participants will receive an education control app and receive non-intervention calls to assess general surgery recovery. Both groups will receive 3 retention calls between 3 and 6 months. Data collection will occur pre-operatively and at 3 and 6 months after surgery.

DISCUSSION

The results of this study will help to determine whether an innovative remotely-delivered, mHealth sedentary reduction intervention can decrease sedentary time in adults after knee replacement.

Associations of maternal stress and/or depressive symptoms with diet quality during pregnancy: a narrative review

BACKGROUND

Pregnancy can be a stressful time for many women; however, it is unclear if higher stress and depressive symptoms are associated with poorer diet quality during pregnancy.

OBJECTIVE

The aims for this narrative review were to (1) synthesize findings of original, peer-reviewed studies that examined associations of stress and/or depressive symptoms with diet quality during pregnancy; (2) review the measurement tools used to assess stress, depressive symptoms, and diet quality; (3) identify current gaps in the extant literature; and (4) offer recommendations for future research.

METHODS

A search strategy was used to identify peer-reviewed manuscripts published between January 1997 and October 2018, using the following databases: PubMed, CINAHL Complete, PsycINFO, Academic Search Complete, and Psychology & Behavioral Sciences Collection. The search was updated December 2019. Two reviewers independently assessed title, abstract, and full-text of the studies that met the inclusion criteria. Data were extracted and a quality assessment was conducted.

RESULTS

Twenty-seven observational studies were identified in this review (21 cross-sectional and 6 longitudinal). In 22 studies, higher stress and/or depressive symptoms were associated with poorer diet quality or unhealthy dietary patterns; 5 studies found no association. Findings are mixed and inconclusive regarding the relationship among stress, depressive symptoms, and food groups related to diet quality and frequency of fast-food consumption.

CONCLUSIONS

The current data suggest stress and depressive symptoms may be a barrier to proper diet quality during pregnancy; however, variability in the assessment tools, timing of assessments, and use of covariates likely contribute to the inconsistency in study findings. Gaps in the literature include limited use of longitudinal study designs, limited use of comprehensive diet-quality indices, underrepresentation of minority women, and lack of multilevel theoretical frameworks. Studies should address these factors to better assess associations of stress and/or depressive symptoms with diet quality during pregnancy.

Stress and Depressive Symptoms Are Not Associated with Overall Diet Quality, But Are Associated with Aspects of Diet Quality in Pregnant Women in South Carolina

BACKGROUND

Poor mental health may hinder diet quality in pregnancy.

OBJECTIVE

This study 1) examined whether stress and depressive symptoms are associated with diet quality (via Healthy Eating Index [HEI] 2015 total scores and dietary intake of food groups/nutrients that align with HEI-2015 components) and 2) tested race as a moderator in the relationship between mental health and diet quality.

DESIGN

This was a cross-sectional analysis of baseline data from a randomized controlled trial collected January 2015 through January 2019 in Columbia, South Carolina. Trained staff administered demographic and psychosocial questionnaires and conducted anthropometric measures. Participants completed two 24-hour dietary recalls, which were self-administered (one on-site, one at home).

PARTICIPANTS

The Health in Pregnancy and Postpartum study was a randomized controlled trial targeting excessive gestational weight gain among pregnant women with overweight/obesity (N = 228).

MAIN OUTCOME MEASURES

The HEI-2015 total scores and food groups/nutrients that align with HEI-2015 were calculated.

STATISTICAL ANALYSES PERFORMED

Multiple linear regression models were used to estimate the relationship between mental health and HEI-2015 total scores and dietary intake of food groups or nutrients that align with HEI-2015 components. Multiplicative interaction terms of stress or depressive symptoms with race were used to determine moderation.

RESULTS

Participants' diet quality was suboptimal (M = 52.0 ± 11.7; range, 27-85). Stress was negatively associated with HEI-2015 total scores (crude but not adjusted model). Stress scores were positively associated with consumption of dairy, refined grains, and added sugars and negatively associated with total protein foods. Depressive symptoms were positively associated with consumption of dairy, refined grains, and saturated fats. Race was not a moderator.

CONCLUSIONS

Diet quality was poor overall, but stress and depressive symptoms were not associated with HEI-2015 total scores in adjusted models. Excluding dairy, stress and depressive symptoms were associated with the consumption of food groups or nutrients related to worse diet quality. These relationships should be examined longitudinally to help establish causality and inform future interventions.

Effective recruitment strategies for African-American men and women: the Nutritious Eating with Soul study

Previous studies have found it challenging to recruit African-American (AA) participants into health education research studies. The goal of this article is to describe the recruitment methods used for the Nutritious Eating with Soul (NEW Soul) study, a 2-year randomized behavioral health education intervention, conducted in two cohorts, with emphasis on methods used for reaching men. Participants indicated how they learned about the study on an online screening questionnaire from a list of the recruitment strategies we employed. Due to limited recruitment of men in Cohort 1, recruitment strategies for Cohort 2 focused on reaching men. Across the two cohorts, a total of 568 (23% men) participants completed the online screener and 159 (21% men) completed all baseline assessments and enrolled in the study. The most effective methods for completing screening questionnaires were radio ads, referrals from friends and family, TV interviews, social media posts and community events. Men were primarily recruited via radio ads, whereas women were more often recruited through TV and social media. Radio was an effective way to recruit AA adults into nutrition interventions, particularly men. In addition, low-cost methods, such as personal referrals, social media posts and community events were also effective strategies.

A Behavioral Lifestyle Intervention to Limit Gestational Weight Gain in Pregnant Women with Overweight and Obesity

OBJECTIVE

This study aimed to evaluate the effects of an antenatal behavioral lifestyle intervention on total gestational weight gain (GWG) and perinatal outcomes.

METHODS

Pregnant women with overweight and obesity in South Carolina were recruited into a theory-based randomized controlled trial (n = 112 intervention, n = 105 standard care), which was designed to target weight self-monitoring, increased physical activity, and improved dietary practices.

RESULTS

Participants were racially/ethnically diverse (44% African American). Intervention and standard care participants had similar total GWG at delivery (12.9 ± 6.9 vs. 12.4 ± 8.3 kg, respectively), but intervention participants had a smaller standard deviation (P = 0.04) in total GWG. The treatment effects were moderated by race/ethnicity and prepregnancy BMI. Among African American participants with overweight, intervention participants gained 4.5 kg less, whereas, among African American women with obesity, intervention participants gained 4.1 kg more than standard care participants. Total GWG among White participants was similar regardless of weight status and group assignment. Fewer intervention participants than standard care participants had adverse pregnancy outcomes (P ≤ 0.01).

CONCLUSIONS

The behavioral lifestyle intervention favorably impacted GWG in African American participants with overweight but not African American participants with obesity. The intervention's overall favorable impact on perinatal outcomes suggests that the mechanisms beyond total GWG may drive these outcomes.

Feasibility of integrating survivors of stroke into cardiac rehabilitation: A mixed methods pilot study

Background

Survivors of stroke are often deconditioned and have limited opportunities for exercise post-rehabilitation. Cardiac Rehabilitation (CR), a structured exercise program offered post-cardiac event in the United States (U.S.), may provide an opportunity for continued exercise.

The purpose of this study was to examine the feasibility of integrating survivors of stroke into an existing, hospital-based CR program through an assessment of (1) recruitment, uptake and retention, (2) adherence and fidelity, (3) acceptability and (4) safety.

Methods

A mixed methods design combined a single group, pre-post design, pilot feasibility study with an imbedded qualitative inquiry. Survivors of stroke were recruited into a standard 12-week, 36 visit CR program.

Results

Fifty-three survivors were referred, 29 started and 24 completed the program. Program uptake rate was 55% and completion rate was 83%. Eleven completers and one non-completer participated in the qualitative interviews. Program completers attended an average of 25.25 (SD 5.82) sessions with an average of 38.93 (SD 5.64) exercise minutes per session while reaching targeted rate of perceived exertion levels. Qualitative themes included perceived benefits of an individualized program in a group setting, positive interactions with qualified staff, opportunities for socialization, and regular monitoring and staff attentiveness promoting feelings of safety.

Conclusions

Survivors of stroke were able to meet Medicare standard dosage (frequency and session duration) and rate of perceived intensity goals, and perceived the program as needed regardless of their mobility limitations or previous exercise experience. Primary challenges included managing referrals and uptake. Results support feasibility and benefit for survivors to integrate into U.S. CR programs.

Healthy Food Density is Not Associated With Diet Quality Among Pregnant Women With Overweight/Obesity in South Carolina

OBJECTIVE

Examine the association and moderating effect of residential location (urban/rural) on the relationship between neighborhood healthy food density and diet quality.

DESIGN

Cross-sectional analysis of baseline data from the Health in Pregnancy and Postpartum study, a randomized trial designed to prevent excessive gestational weight gain.

PARTICIPANTS

Pregnant women in South Carolina with prepregnancy overweight/obesity (n = 228).

MAIN OUTCOME MEASURES

Healthy Eating Index-2015 (HEI) was used to measure diet quality from 2 24-hour dietary recalls. The HEI total scores and 11 binary HEI components (those that met the standard for maximum component score vs those that did not) were calculated as dependent variables.

ANALYSIS

Multiple linear and logistic regression models were used to examine the association between healthy food density and HEI total scores and meeting the standards for maximum component scores. Healthy food density × residential location tested for moderation. P < 0.05 indicated significance.

RESULTS

Participants' diet quality was suboptimal (mean, 52.0; SD, 11.7; range, 27-85). Healthy food density was not significantly related to HEI total scores or components, and residential location was not a moderator.

CONCLUSIONS AND IMPLICATIONS

Diet quality was suboptimal, and there was no relationship between healthy food density and diet quality among Health in Pregnancy and Postpartum study participants. These data support examining behavioral factors that could influence diet quality.

Integrating Survivors of Stroke Into Exercise-Based Cardiac Rehabilitation Improves Endurance and Functional Strength

Background

Cardiac rehabilitation (CR) is a structured exercise program prevalent in the United States for people with cardiovascular disease that has been shown to increase cardiovascular endurance and improve quality of life. Despite similar cardiovascular risk factors, stroke is not among the covered diagnoses for CR. The purpose of this study was to examine the participant impact of integrating survivors of stroke into the exercise portion of an existing hospital‐based CR program through measures of physical function and other health impacts and through qualitative evaluation of participant perception.

Methods and Results

Subacute and chronic survivors of stroke were integrated into a standard 12‐week, 3 sessions per week, exercise‐based CR program. A total of 29 began the program, 24 completed the program, and 18 were available for 6‐month follow‐up. Quantitative measures were compared preprogram with postprogram with t‐test or equivalent, and preprogram with postprogram to 6‐month follow‐up with ANOVA or equivalent. Semistructured interviews were completed with 11 participants postprogram. Exercise‐based CR had significant impacts on cardiovascular endurance preprogram to postprogram, with maintenance at 6‐month follow‐up. The participants improved on the 6‐minute walk test on average by 61.92 m(95% CI, 33.99–89.84 m), and maximum metabolic equivalents improved by a median of 3.6 (interquartile range, 2.35). Five times sit to stand (functional strength) improved preprogram to postprogram by a median of 2.85 s (interquartile range, 4.03 s). Qualitative findings highlight additional health improvements. Most participants (83% [15/18]) reported continued exercise at follow‐up.

Conclusions

Exercise‐based CR has the potential to improve cardiovascular endurance, health status, and quality of life for survivors of stroke.

Persistence and transience of food insecurity and predictors among residents of two disadvantaged communities in South Carolina

BACKGROUND

Little is known about patterns of household food insecurity (HFI) across more than two time points in adults in the United States, the frequency predictors of different trajectories. The distinctions between persistent and transient food insecurity trajectories may be crucial to developing effective interventions.

OBJECTIVE

To characterize dominant trajectories of food security status over three time points between 2013 and 2016 and identify demographic, socioeconomic and health-related predictors of persistent and transient HFI.

DESIGN

Cohort study in disadvantaged communities in South Carolina.

SETTING

and subjects: 397 middle-aged participants, predominantly female, African American, living in USDA-designated food deserts.

MAIN OUTCOME MEASURE

Household food insecurity over time using the 18-item USDA's Household Food Security Survey Module.

STATISTICAL ANALYSES PERFORMED

Descriptive analyses of food security trajectories and multinomial regression analyses.

RESULTS

At baseline (2013-2014), 61% of households reported HFI during the previous 12 months, which decreased to 54% in 2015 and to 51% in 2016. Only 27% of households were persistently food secure, 36% experienced transient and 37% persistent food insecurity. Female sex (OR 2.7, 95%CI 1.2-5.9), being married or living with a partner (OR 2.4, 95CI% 1.1-5.3) and fair health status (OR 4.4, 95%CI 2.2-8.8) were associated with increased odds of persistent food insecurity. Fair health was also a significant predictor of transient food insecurity.

CONCLUSIONS

These findings suggest that future research should focus on persistent versus transient trajectories separately and that tailored interventions may be needed to make progress on alleviating food insecurity among disadvantaged communities.
