Interventions for improving nutrition and physical activity behaviors in adult African American populations: a systematic review, January 2000 through December 2011

Using formative process evaluation to improve program implementation and accessibility of competitive group-based physical activity in the TEAM-PA trial

BACKGROUND

This study demonstrates how formative process evaluation was used to assess implementation and improve dose and fidelity in the Together Everyone Achieves More Physical Activity (TEAM-PA) randomized controlled trial. TEAM-PA uses a randomized group cohort design to evaluate the efficacy of a group-based intervention for increasing physical activity among African American women.

METHODS

Intervention groups met for 10 weeks and were co-led by female African American facilitators, with intervention sessions consisting of group feedback, a health curriculum, group-based physical activity games, and group-based goal-setting. Drawing from a multi-theoretical framework, the intervention targeted social affiliation using collaborative and competitive group strategies, including essential elements focused on group-based behavioral skills, peer-to-peer positive communication, collectivism, optimal challenge, social facilitation, and peer to peer challenges. Formative process evaluation was used to monitor reach, dose, and fidelity, and implement feedback and solutions.

RESULTS

Across two cohorts, four groups (n = 54) were randomized to the TEAM-PA intervention. On average 84.8% of participants attended each week, which exceeded the a priori criteria. Results from the systematic observations indicated that on average 93% of the dose items were completed in each session and adequate levels of fidelity were achieved at both the facilitator and group-levels. Participants were compliant with wearing the FitBits (6.73 ± 0.42 days/week) and most participants successfully contributed to meeting the group-based goals. The use of open-ended items also revealed the need for additional modifications to the group-based PA games, including allowing for individuals to take breaks, incorporating a broader range of exercises, minimizing activities that required bending/reaching down without assistance, and providing facilitators with additional training for implementing the games. Initial evidence suggests that these changes were successful in increasing participants' comprehension of the games from Cohort 1 (M = 1.83, SD = 0.71) to Cohort 2 (M = 3.33, SD = 0.69).

CONCLUSION

Findings from this study demonstrated high levels of reach, dose, and fidelity, while also highlighting strategies for implementing competitive group-based PA games that are accessible across physical fitness levels. Formative process evaluation, including open-ended items and collaborative brainstorming, holds tremendous potential for improving future interventions.

TRIAL REGISTRATION

This study was registered on Clinicaltrials.gov (# NCT05519696) on August 22, 2022 prior to the enrollment of the first participant on September 12, 2022 ( https://clinicaltrials.gov/study/NCT05519696?term=NCT05519696&rank=1 ).

Impact of Nutrition Education on Various Health-Related Components of Hemodialysis Patients: A Systematic Review

This study aimed to identify the impact of nutrition education on various health-related components of hemodialysis patients. A systematic review was conducted according to the PRISMA guidelines. Relevant literature published between 2013 and 2023 was identified across two databases (PubMed and Science Direct). The protocol was registered in PROSPERO (CRD42023460681). Two independent reviewers retrieved the data, and 41 studies were selected. Nine components related to the impact of nutrition education in hemodialysis patients were identified. Each component was clarified by mentioning each study and its results. This study enabled us to characterize the various components of the impact of nutritional education in hemodialysis patients, namely biological markers, quality of life, cost of care, adherence to dietary recommendations, knowledge, malnutrition inflammation, dietary intake, weight change, and behavior change. This systematic review enables healthcare providers to assess the impact of nutritional education on hemodialysis patients. Also, it gives professionals an exact idea of the impact of nutrition education on hemodialysis patients, with knowledge of new methods using behavior change theories and innovative technological tools.

Engaging Faith-Based Organizations to Promote Health Through Health Ministries in Washington, DC

This article describes capacity building and formative assessments completed at five faith-based organizations (FBOs) in Washington, DC to inform sustainable health promotion programming led by certified health ministers. Five FBO partners were recruited with two congregation members from each FBO completing a health minister certificate program. A series of health assessments were conducted to assess each FBO's capacity to implement evidence-based lifestyle change programs that are responsive to congregation members' health needs. Results indicated a need for programming to support older adults in managing high blood pressure and arthritis. Health ministers represent a significant opportunity for building capacity within FBOs to deliver programming that can improve health outcomes.

Differences in provider recommendations for Black/African American and White patients with irritable bowel syndrome

BACKGROUND

Health disparities and barriers to equitable care for patients from racial and ethnic minority backgrounds are common. We sought to evaluate disparities in management recommendations among Black/African American (AA) patients seeking care for IBS.

METHODS

We assembled a retrospective cohort of patients at two tertiary care centers who were self-identifying as Black/AA and attended a first gastroenterology consult for IBS. These patients were age- and sex-matched to White controls with IBS also attending an initial gastroenterology consult. Retrospective chart review determined patient demographics, income, comorbidities, as well as provider management recommendations including pharmacologic therapies and non-pharmacologic interventions.

KEY RESULTS

Among 602 IBS patients ages 14-88 (M ± SD = 43.6 ± 18.6 years) with IBS, those who identified as Black/AA (n = 301) had a lower estimated mean income and were significantly more likely to have a number of specific chronic medical conditions. Black/AA patients were significantly less likely to have implemented dietary changes for symptoms prior to receiving a diagnosis of IBS from a gastroenterologist. Black/AA patients were also less likely to receive a referral to a dietician within 1 year following their diagnosis of IBS (p = 0.01). Black/AA patients were prescribed pharmacologic therapy more often for constipation (41.9% vs. 34.6%, p = 0.01). It was more common for White patients to present at the initial encounter having already initiated a neuromodulator (41.9% vs. 27.9%, p < 0.001).

CONCLUSION & INFERENCES

Management recommendations for IBS appear to vary by race, specifically for dietary advice and referrals.

African Americans' perceptions of nutrition interventions: a scoping review

Nutrition education and policy, systems and environmental (PSE) change interventions may be able to address food insecurity and obesity, conditions which are disproportionately experienced by African Americans. Work that seeks to address these disparities and advance social justice should uplift and learn from participant voices, particularly from marginalised groups. This scoping review aimed to summarise the available literature describing African Americans' perceptions of and experiences participating in nutrition interventions. We conducted an electronic literature search with the assistance of a research librarian which encompassed six databases (MEDLINE, PyscINFO, Agricola, ERIC, SocINDEX and ProQuest Dissertations & Theses) and identified thirty-five sources meeting our inclusion criteria. The majority of studies assessing African Americans' satisfaction with interventions examined educational interventions alone, and about half of the included studies assessed satisfaction through quantitative methods alone. The only studies which found participants to be dissatisfied with interventions used qualitative methods and examined interventions providing education alone. Future work should evaluate African Americans' experience with nutrition-focused PSE changes, interventions which may be better able to address racial disparities in obesity and food insecurity. Nutrition educators working with African Americans should also consider evaluating future interventions using qualitative inquiry, to obtain an in-depth understanding of participant experiences with interventions.

An Examination of Culturally Relevant Health Messages in African-American Churches

This quantitative study examined the presence of culturally relevant health messages for African-Americans based on a preexisting dataset from 21 African-American churches in South Carolina (USA). Content analysis served as the primary methodological approach to code printed media messages based on their cultural relevance among African-Americans (Cohen's kappa = .74). Within the dataset (n = 2166), 477 (22%) items were identified as culturally relevant. A low prevalence of culturally relevant messages was found across the three message topics, two media types, and one media source. Due to the limited presence of culturally relevant messages, researchers should collaborate with African-American churches to design health promotion messages.

African American Perceptions of Service Provided by Supplemental Nutrition Assistance Program-Education: A Qualitative Exploration

OBJECTIVE

To assess African Americans' satisfaction with Supplemental Nutrition Assistance Program-Education (SNAP-Ed) in Louisiana.

METHODS

African American facilitators conducted 5 focus group discussions with 25 African American SNAP-Ed participants according to issues identified by African American SNAP-Ed implementers in Louisiana. Focus group discussion transcripts were coded independently using inductive and in vivo coding by 2 members of the research team.

RESULTS

Participants viewed lessons as race-neutral and thought they should include more information about African American history and culture. Participants also noted a lack of engagement with the African American community and stressed the need for the program to employ African American staff. However, participants thought the information was important for African Americans in the context of medical issues faced by their community.

CONCLUSIONS AND IMPLICATIONS

Findings indicate that SNAP-Ed in Louisiana be modified to address African American food history and culture, additional African American staff and better engagement with the African American community.

Results from "Developing Real Incentives and Volition for Exercise" (DRIVE): A pilot randomized controlled trial for promoting physical activity in African American women

OBJECTIVE

Motivation is a barrier to physical activity (PA) among African American (AA) women, but past studies have implemented a "one-size-fits-all" approach and have not addressed differences in autonomous motivation. This pilot randomized controlled trial assessed the preliminary efficacy of "Developing Real Incentives and Volition for Exercise," a community- and theory-based intervention, which evaluated whether a motivationally matched (vs. a nonmatched) intervention increases daily total PA.

METHOD

In total, 68 AA women (50.72 ± 13.66 years; 86.8% with obesity) were randomized to an 8-week challenge-focused program (targeted toward high autonomous motivation) or rewards-focused program (targeted toward low autonomous motivation). Randomization was stratified by baseline autonomous motivation. FitBits were used during the intervention to promote self-monitoring (both programs) and social connectedness (challenge program only).

RESULTS

Both programs retained ≥ 80% of participants. Process evaluation revealed high attendance, dose, and fidelity (both programs). However, contrary to expectations, across all motivational levels (low and high autonomous), the challenge-focused intervention resulted in a greater increase in total daily PA (primary outcome), with an average increase of 17.9 min in the challenge-focused intervention versus an average decrease of 8.55 min in the rewards-focused intervention. An exploratory follow-up analysis revealed that engagement with the FitBit mobile app predicted greater PA at postintervention in the challenge-focused program.

CONCLUSIONS

A team-based approach targeting social connectedness, enjoyment of PA, and positive intragroup competition is a promising approach for promoting PA among AA women. These findings are used to guide a discussion on best practices for engaging AA women in future behavioral interventions. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Community-based, cluster-randomized pilot trial of a cardiovascular mHealth intervention: Rationale, design, and baseline findings of the FAITH! Trial

BACKGROUND

Compared to whites, African-Americans have lower prevalence of ideal cardiovascular health (CVH) based on the American Heart Association Life's Simple 7 (LS7). These CVH inequities have worsened during the COVID-19 pandemic. Ideal LS7 health-promoting behaviors and biological risk factors (eg, diet, blood pressure) are associated with improved CVH outcomes. The FAITH! (Fostering African-American Improvement in Total Health) App, a community-informed, mobile health (mHealth) intervention, previously demonstrated significant improvements in LS7 components among African-Americans, suggesting that mHealth interventions may be effective in improving CVH. This paper presents the FAITH! Trial design, baseline findings, and pandemic-related lessons learned.

METHODS

Utilizing a community-based participatory research approach, this study assessed the feasibility/preliminary efficacy of a refined FAITH! App for promoting LS7 among African-Americans in faith communities using a cluster, randomized controlled trial. Participants received the FAITH! App (immediate intervention) or were assigned to a delayed intervention comparator group. Baseline data were collected via electronic surveys and health assessments. Primary outcomes are change in LS7 score from baseline to 6-months post-intervention and app engagement/usability.

RESULTS

Of 85 enrolled individuals, 76 completed baseline surveys/health assessments, for a participation rate of 89% (N = 34 randomized to the immediate intervention, N = 42 to delayed intervention). At baseline, participants were predominantly female (54/76, 71%), employed (56/76, 78%) and of high cardiometabolic risk (72/76, 95% with hypertension and/or overweight/obesity) with mean LS7 scores in the poor range (6.8, SD = 1.9).

CONCLUSIONS

The FAITH! Trial recruitment was feasible, and its results may inform the use of mHealth tools to increase ideal CVH among African-Americans.

Exploring the Readiness of African-American Churches to Engage in a Community-Engaged Blood Pressure Reduction Research Study: Lessons Learned from the Church Challenge

Introduction

The Transtheoretical Model (TTM) has been used to assess individual readiness for health behavior change. We describe our use of the TTM to assess organizational readiness of African-American churches to participate in the Church Challenge (CC) in Flint, Michigan; the processes of change that moved churches toward readiness for change; and lessons learned.

Methods

The CC was a faith-based, multilevel intervention to reduce chronic disease risk. A community-based participatory approach was used to engage and recruit churches. We used the TTM to capture church readiness for change and track church progress through the five stages.

Results

We engaged with 70 churches: 35 remained in Stage 1 (precontemplation), 10 remained in Stage 2 (contemplation), 3 remained in Stage 3 (preparation), 5 made it to Stage 4 (action), and 17 finished within Stage 5 (maintenance). Churches engaged in several processes of change as they moved through the various stages of change.

Lessons Learned

Utilizing processes of change, establishing rapport, and having previous participants share success stories helped move churches from stage-to-stage. However, certain barriers prevented progression, such as burnout/trauma from the Flint Water Crisis and scheduling conflicts.

Discussion

Faith-based organizational readiness greatly impacted participation in the CC. Researchers should utilize established social capital, build rapport, and remain flexible when working with African-American churches.

Conclusion

Although traditionally used at the individual level, the TTM works well at the organizational level to assess and monitor church readiness to participate in community-engaged research and health programming to improve health in an African-American faith community.

A Lifestyle Intervention Program to Improve Knowledge and Health Behaviors in Women

OBJECTIVE

To improve health knowledge, facilitate healthy behaviors, and provide social support for a high-risk population of women by implementing a culturally tailored, gender-specific lifestyle intervention program.

DESIGN

Evidence-based practice project.

SETTING/LOCAL PROBLEM

A Chicago neighborhood in Cook County, Illinois, where there are increased rates of diabetes, heart disease, cancer, stroke, hypertension, obesity, preterm birth, and violent crime.

PARTICIPANTS

Female residents of the community, ages 19 to 45 years; 12 participants registered for the program, and 11 participants completed the entire 2-month program.

INTERVENTIONS/MEASUREMENTS

The BE WISE Lifestyle Intervention, a culturally tailored, gender-specific behavior change curriculum, was used for this project. An interprofessional team was used to enhance participant experience, and neighborhood collaborations were established to create sustainability of efforts. Pre- and postintervention measures of diet, physical activity, social support, and knowledge acquisition were used to evaluate outcomes.

RESULTS

Improvement was noted for knowledge in most of the content areas, as well as for dietary and physical activity behaviors. All participants rated the program highly and responded positively to the social support experienced in the group.

CONCLUSION

Culturally tailored lifestyle interventions can be effective in improving knowledge and encouraging behavior change, especially when delivered in group settings to enhance social support. Community-level collaborations enhance interventions by providing local support and resources for participants. Because behavior change takes time, follow-up at the 6-month and 1-year intervals is recommended to determine longer-term outcomes.

Nutrition Interventions Addressing Structural Racism: A Scoping Review

African Americans experience high rates of obesity and food insecurity in part due to structural racism, or overlapping discriminatory systems and practices in housing, education, employment, health care, and other settings. Nutrition education and nutrition-focused policy, systems, and environmental changes may be able to address structural racism in the food environment. This scoping review aimed to summarize the available literature regarding nutrition interventions for African Americans that address structural racism in the food environment and compare them to the "Getting to Equity in Obesity Prevention" framework of suggested interventions. An electronic literature search was conducted with the assistance of a research librarian encompassing 6 databases-MEDLINE, PyscINFO, Agricola, ERIC, SocINDEX, and ProQuest Dissertations & Theses. A total of 30 sources were identified detailing interventions addressing structural barriers to healthy eating. The majority of nutrition interventions addressing structural racism consisted of policy, systems, and/or environmental changes in combination with nutrition education, strategies focused on proximal causes of racial health disparities. Only two articles each targeted the "reduce deterrents" and "improve social and economic resources" aspects of the framework, interventions which may be better suited to addressing structural racism in the food environment. Because African Americans experience high rates of obesity and food insecurity and encounter structural barriers to healthy eating in the food environment, researchers and public health professionals should address this gap in the literature.

Sign of the times: Community engagement to refine a cardiovascular mHealth intervention through a virtual focus group series during the COVID-19 Pandemic

Background

African-Americans are underrepresented in mobile health intervention research studies which can perpetuate health inequities and the digital divide. A community-based, user-centered approach to designing mobile health interventions may increase their sociocultural relevance and effectiveness, especially with increased smartphone use during the coronavirus disease 2019 pandemic. We aimed to refine an existing mobile health intervention via a virtual focus group series.

Methods

African-American community members (n = 15) from churches in Minneapolis-St. Paul and Rochester, Minnesota were enrolled in a virtual (via videoconferencing), three-session focus group series over five months to refine a cardiovascular health-focused mobile health application (FAITH! [Fostering African-American Improvement in Total Health!] App). Participants accessed the app via their smartphones and received a Fitbit synced to the app. Participants engaged with multimedia cardiovascular health-focused education modules, a sharing board for social networking, and diet/physical activity self-monitoring. Participant feedback on app features prompted iterative revisions to the FAITH! App. Primary outcomes were app usability (assessed via Health Information Technology Usability Evaluation Scale range: 0–5) and user satisfaction.

Results

Participants (mean age [SD]: 56.9 [12.3] years, 86.7% female) attended a mean 2.8 focus groups (80% attended all sessions). The revised FAITH! App exceeded the goal Health Information Technology Usability Evaluation Scale score threshold of ≥4 (mean: 4.39, range: 3.20–4.95). Participants positively rated updated app content, visual appeal, and use of social incentives to maintain engagement. Increasing user control and refinement of the moderated sharing board were identified as areas for future improvement.

Conclusions

Community-partnered, virtual focus groups can optimize usability and increase participant satisfaction of mobile health lifestyle interventions that aim to promote cardiovascular health in African-Americans.

Laparoscopic Vertical Sleeve Gastrectomy as a Treatment Option for Adults with Diabetes Mellitus

Obesity is a major factor in the worldwide rise in the prevalence of type 2 diabetes mellitus. The obesity "epidemic" will require novel, effective interventions to permit both the prevention and treatment of diabetes caused by obesity. Laparoscopic vertical sleeve gastrectomy is a newer bariatric surgical procedure with a lower risk of complications (compared to Roux-en-Y gastric bypass surgery). Based in part on restriction of daily caloric intake, sleeve gastrectomy has a major role in inducing significant weight loss and weight loss is maintained for at least 10 years. Prior studies have supported the utility of the vertical sleeve gastrectomy for the treatment and management of subgroups of individuals with diabetes mellitus. There are reports of 11% to 76.9% of obese individuals discontinuing use of diabetic medications in studies lasting up to 8 years after vertical sleeve gastrectomy. Major ongoing issues include the preoperative determination of the suitability of diabetic patients to undergo this bariatric surgical procedure. Understanding how this surgical procedure is performed and the resulting anatomy is important when vertical sleeve gastrectomy is being considered as a treatment option for diabetes. In the postoperative periods, specific macronutrient goals and micronutrient supplements are important for successful and safer clinical results. An understanding of immediate- and long term- potential complications is important for reducing the potential risks of vertical sleeve gastrectomy. This includes the recognition and treatment of postoperative nutritional deficiencies and disorders. Vertical sleeve gastrectomy is a component of a long term, organized program directed at treating diabetes related to obesity. This approach may result in improved patient outcomes when vertical sleeve gastrectomy is performed to treat type 2 diabetes in obese individuals.

A mixed-methods protocol for identifying successful sustainability strategies for nutrition and physical activity interventions in childcare

BACKGROUND

Despite the importance of sustainability for nutrition and physical activity in public health interventions, limited studies have explored the factors that promote and inhibit evidence-based program sustainment in the childcare setting. This study protocol describes a mixed-methods approach to develop novel sustainability strategies based on real-world settings and stakeholder feedback, with the goal of providing support for future obesity prevention programs and related studies on intervention sustainability. Two interventions, Together, We Inspire Smart Eating (WISE) and The Food Friends' (FF) Fun with New Foods and Get Movin' with Might Moves, are studied to this end.

METHODS

The study will deploy an explanatory, sequential mixed-methods design. First, the research team will collect a quantitative survey to assess rates of sustainment among WISE and Food Friends sites. We expect to collect 150 surveys from WISE and FF sites combined. Data from these surveys will be used to purposively sample sites for 12 to 18 site visits. Specifically, we will purposively sample low, partial, and high sustaining sites where we will conduct key informant interviews and focus groups as well as validate self-reports on sustainability. Survey content, qualitative interviews, and coding will be based on the Dynamic Sustainability Framework. We will draw on findings from the quantitative survey on predictors of sustainment and the qualitative site visits to understand varying levels of program sustainment. Then, we will utilize evidence-based quality improvement sessions to engage stakeholders in developing a multi-component sustainability strategy.

DISCUSSION

This study will provide a stakeholder-informed sustainability strategy ready for testing in a full-scale trial examining effects on sustainment of evidence-based nutrition and physical activity practices in childcare. We expect this strategy to be relevant for educators and consistent with the views of administrators as a guide for future practice for the targeted nutrition and physical activity interventions and beyond.

Impact of the Serum Level of Albumin and Self-Assessed Chewing Ability on Mortality, QOL, and ADLs for Community-Dwelling Older Adults at the Age of 85: A 15 Year Follow up Study

Quality of life (QOL) and mortality are true endpoints of epidemiological or medical research, especially for community-dwelling older adults. Nutritional status and activities of daily living (ADLs) are associated with QOL and mortality. Good oral health status supports a good nutritional status. The aim of this study was to elucidate the complex structure of these important health-related factors. We surveyed 354 healthy older adults at the age of 85. Nutritional status was evaluated by the serum level of albumin. QOL, ADLs, self-assessed chewing ability, serum albumin level, and mortality during the 15 year follow up period were analyzed. Self-assessed chewing ability was associated with QOL and ADLs. Self-assessed chewing ability for slight-hard foods was associated with mortality in men. However, it was not associated with the serum albumin level. The serum albumin level was associated with mortality in women. These results indicate that maintaining good oral function is not enough. Nutritional instruction in accordance with oral function is indispensable for health promotion in older adults. When planning health promotion strategies for older adults, different strategies are needed for men and women.

Nutrition Self-Efficacy and Dietary Patterns among Older African American Women in Kansas

INTRODUCTION

Nutrition is the key contributor to disparities in many chronic diseases. However, little is known about the dietary habits and nutrition self-efficacy beliefs of older African American women with chronic diseases. This study looked at the relationship between nutrition self-efficacy and dietary patterns among older African American women.

METHODS

A total of 115 African American women 55 years and older, with one or more chronic diseases such as hypertension, diabetes, and hyperlipidemia, were recruited from a midwestern city in Kansas. Participants completed a survey comprised of dietary intake items and the Physical Activity and Nutrition Self-Efficacy (PANSE) scale. Data were analyzed with descriptive statistics, Spearman correlation, and Wilcoxon rank sum test (Mann-Whitney U Test).

RESULTS

There was a 79% (91/115) participation rate. Participants were confident in their ability to maintain healthy behaviors (57.67/72; SD = 11.22). The mean dietary score for fats and carbohydrate consumption was 32.67 ± 2.48 compared to 5.89 ± 3.52 for fruit and vegetable intake. A significant positive correlation was observed between fruit and vegetable intake and nutrition self-efficacy. A higher fruit and vegetable intake were observed among married women (mean = 7.35; SD = 4.45).

CONCLUSION

Our findings shed new light on older African American women's perceptions of healthy eating and the confidence to eat heathy. Based on these results, older African American women met the daily fruit and vegetable recommendations; however, more work is needed to understand how to intervene to improve dietary behaviors regarding fat and carbohydrate consumption in this population. While more research is needed, the findings indicated behavioral theories such as nutrition self-efficacy may have utility in tailoring nutrition interventions in an older African American population.

Mobile App-Based Small-Group Physical Activity Intervention for Young African American Women: a Pilot Randomized Controlled Trial

A lack of adequate physical activity among young African American women remains a serious public health challenge. Few evidence-based interventions are available to increase physical activity in this population, and none has leveraged mobile technologies, even though African Americans are among the most avid users of mobile applications (apps). We conducted a pilot randomized controlled trial to test the efficacy of a mobile app-based small-group intervention in increasing physical activity among African American women aged 18 to 35 years (N = 91) in Philadelphia, PA. Cohorts of eight participants were randomized in a 1:1 ratio to a 4-women small-group intervention or an individual control condition. Control participants used the app to track their own activities. Small-group participants could track their own activities and those of the other three women in their group and could message the other women using a chatting tool. The primary outcome was meeting the goal of engaging in at least 90 min/day of light physical activity during the 3-month study period objectively assessed by a Fitbit device. Data were collected in 2016 and analyzed in 2017. Group participants had higher odds of meeting the goal (OR = 1.48, p = .048) than did control participants, an effect that did not wane during the 3-month study period. Irrespective of condition, participants had lower body-mass index (p = .01) and performed more push-ups (p < .0001) at the 1-month and 3-month assessments compared with the baseline measures. Mobile apps facilitating small online groups can contribute to efforts to increase physical activity among young African American women.This study is registered at www.clinicaltrials.gov NCT02736903.

The Importance of the Social Environment in Achieving High Levels of Physical Activity and Fruit and Vegetable Intake in African American Church Members

PURPOSE

African Americans experience a high burden of chronic diseases and cancers that are prevented and ameliorated with physical activity (PA) and fruit and vegetable (FV) intake. The purpose of this study is to identify individual, social, and neighborhood variables associated with African Americans attaining high levels of both behaviors.

DESIGN

This study is a cross-sectional analysis.

SETTINGS AND PARTICIPANTS

Cohort of African Americans adults recruited from black churches in the Greater Houston area.

MEASURES

Self-administered questionnaires collected in 2012 assessed correlates and behavioral outcome variables (PA and FV consumption). A combined 4-category behavioral outcome was created: high PA/high FV, low PA/high FV, high PA/low FV, and low PA/low FV.

ANALYSIS

Standard and stepwise multinomial logistic regression examined the association between the various variables and the behavioral outcome.

RESULTS

This sample (n = 1009) had a mean age of 49 years, was mostly female, and obese. Compared to the low PA/low FV intake group, the high PA/high FV intake group had significantly lower odds of individual-level variables (worrying about getting cancer, perceived stress, loneliness, and financial strain) and higher odds of social-level variables (social status, social cohesion, social organization involvement, and social norms). Only social-level variables remained significantly associated with higher odds of high PA/high FV intake in stepwise regression.

CONCLUSION

These findings indicate that social influences may be most critical for high PA and FV intake in African Americans adults.

Impact of a Web-Based Exercise and Nutritional Education Intervention in Patients Who Are Obese With Hypertension: Randomized Wait-List Controlled Trial

Background

Internet-based interventions are a promising strategy for promoting healthy lifestyle behaviors. These have a tremendous potential for delivering electronic health interventions in scalable and cost-effective ways. There is strong evidence that the use of these programs can lead to weight loss and can lower patients’ average blood pressure (BP) levels. So far, few studies have investigated the effects of internet-based programs on patients who are obese with hypertension (HTN).

Objective

The aim of this study is to investigate the short- and long-term efficacy, in terms of body composition and BP parameters, of a self-administered internet-based intervention involving different modules and learning techniques aimed at promoting lifestyle changes (both physical activity and healthy eating) in patients who are obese with HTN.

Methods

A randomized wait-list controlled trial design was used. We recruited 105 adults with HTN who were overweight or obese and randomly assigned them to either a 3-month internet-based intervention group (n=55) or the wait-list control group (n=50). We assessed BMI (primary outcome), body fat mass (BFM), systolic (S)BP and diastolic (D)BP, blood glucose and insulin levels, physical activity levels, and functional capacity for aerobic exercise at Time 0 (preintervention) and Time 1 (postintervention). All the patients in the wait-list control group subsequently received the intervention, and a secondary within-group analysis, which also included these participants, was conducted at Time 2 (12-month follow-up).

Results

A 2-way mixed analysis of covariance showed a significant decrease in BMI, BFM, and blood glucose at 3 months in the internet-based intervention group; the effect size for the BMI and BFM parameters was moderate to large, and there was also a borderline significant trend for DBP and insulin. These results were either maintained or improved upon at Time 2 and showed significant changes for BMI (mean difference −0.4, 95% CI −0.1 to −0.6; P=.005), BFM (mean difference −2.4, 95% CI −1.1 to −3.6; P<.001), DBP (mean difference −1.8, 95% CI −0.2 to −3.3; P=.03), and blood glucose (mean difference −2, 95% CI 0 to −4; P=.04).

Conclusions

Implementation of our self-administered internet-based intervention, which involved different learning techniques aimed to promote lifestyle changes, resulted in positive short- and long-term health benefits in patients who are obese with HTN.

A qualitative study to examine how differences in motivation can inform the development of targeted physical activity interventions for African American women

Self-Determination Theory proposes that some people are motivated to initiate physical activity by externally-controlled reasons (e.g., physical appearance, approval from others), whereas others feel compelled by more autonomous sources of motivation (e.g., enjoyment, personal importance). This study used qualitative methods to examine whether individual differences in autonomous motivation offers a useful framework for developing targeted intervention programs for African American women. Focus groups (k = 6) were conducted to examine how different levels of autonomous motivation for physical activity related to differences in physical activity barriers and facilitators among African American women (N = 31). Sessions were audiotaped, transcribed, and coded by independent raters (r = 0.70). QSR NVivo 11 was used to analyze data, and themes were identified separately for women with low, medium, or high autonomous motivation. Those with high autonomous motivation focused on themes of wanting novelty, excitement, and competition, whereas those with low autonomous motivation focused on themes of wanting instrumental support and financial incentives for increasing engagement in physical activity. Implications for developing physical activity intervention programs for African American women that are targeted toward differences in autonomous motivation are discussed.

The Breast-Cancer Education and Wellness (BE Well) Intervention: Congregants' Intended Participation, Actual Participation, and Perceived Health Outcomes

Objective. To evaluate a health leader-focused church-based breast cancer prevention intervention in relation to congregants' intended participation, congregants' actual participation, and perceived health outcomes at both individual and church levels using socio-ecological and theory of planned behavior frameworks. Method. Participants for the study were African American adults (n = 52) from six churches in a North Florida county involved in implementing the 9-month, three-phase intervention. Using a pre/post without comparison group design, data were collected via self-administered surveys and analyzed using qualitative and quantitative (descriptive, analysis of variance, linear regression) procedures. Results. There was general alignment between congregants' intended and actual participation when analyzed by content, especially in the areas of food and nutrition and health education. Regarding the number of intended versus actual activities, there was a significant, negative change in physical activity, a slight decline in health education activities, but a slight increase in food and nutrition activities. No significant relationships were found between extent of participation and the individual health outcomes (health ratings, health status), but significant relationships were found between extent of participation and church health outcomes (perceived role of church in improving health, p < .001; perceived role of the pastor in improving health, p < .001). Conclusions. The findings demonstrate that (1) congregants may follow through and participate in church-based health activities in which they express interest and that are made available and (2) the extent of their participation may be influenced by the perceived role of both the church and the pastor in improving their health.

The Church Challenge: A community-based multilevel cluster randomized controlled trial to improve blood pressure and wellness in African American churches in Flint, Michigan

Chronic disease carries high morbidity and mortality in the United States, with large racial and ethnic disparities observed in chronic disease. Physical activity and healthy food are vital for chronic disease prevention yet challenging to access in economically distressed areas. Public health prevention efforts have become particularly prominent within faith-based organizations over the last three decades. This manuscript describes the protocol of the Church Challenge, a multilevel cluster-randomized controlled nutrition and physical activity trial across 24 churches to reduce blood pressure by 6 mmHg among 576 residents in Flint, MI. The Church Challenge was developed using community-based participatory approaches and is rooted in a church-based program developed by and for primarily African-American Flint church congregations. This three-level intervention addresses health at the community (level 3), church (level 2), and individual (level 1) to reduce blood pressure, reduce chronic disease risk, and promote health equity and wellbeing in Flint. Churches are randomized in a 1:1 ratio to a 16-week physical activity and nutrition program or a 4-session health and wellness workshop. Flint is not a unique community but has a history of traumatic community wide events; even now, the public health infrastructure continues to be a challenge and distract residents from focusing on their health. This trial is highly significant and innovative because it uses a combination of evidence-based practices simultaneously supporting health behavior change for individuals and their faith organizations, and evaluates multilevel efforts to sustain long-term health promotion activities in vulnerable communities like Flint.

University⁻Community Partnerships Using a Participatory Action Research Model to Evaluate the Impact of Dance for Health

Little is known about fostering sustainable, collaborative community-academic partnerships that effectively improve physical activity and health in residents of under resourced communities using Participatory Action Research (PAR) driven models. The purpose of this PAR study was to evaluate the impact of an urban, intergenerational, and physical activity dance program by identifying community preferred measurable outcomes that promote program participation and sustainability. A descriptive, qualitative design was employed using semi-structured interview guides to facilitate discussions for two adult focus groups and one youth focus group. Exactly 19 community-residing adults and six youth who lived in urban neighborhoods in West Philadelphia participated in the discussions. The audiotapes were transcribed and analyzed using directed content analysis. Five outcome themes emerged and included: (1). Enhancing the psychological and emotional well-being of the individual, (2). Enhancement of social well-being and management of interpersonal relationships and responsibilities (3). Enhancing and promoting physiologic well-being (4). Changes in health promoting behaviors and skill acquisition, and (5). Concerns about accessibility of dance for health and other physical activity programs in the community. Focused attention to measuring community preferred outcomes can promote sustainability of Dance for Health and possibly other urban-based physical activity dance programs.

Texting Older Sisters to Step: The TOSS Study

The purpose of our two-phase study was to develop acceptable text messages to increase physical activity. Four focus groups (two for each phase) were conducted with older African American women who had access to texting-capable mobile phones and were in the contemplation stage for physical activity. The mean age of Phase 1 participants (n = 12) was 71 and ranged from 65 to 86 years. Content analysis was used to identify fundamental themes that were later used to develop text messages. Six categories emerged from the data and 31 text messages were developed based on focus group input and national recommendations. The mean age of Phase 2 participants (n = 9) was 67 and ranged from 65 to 75 years. Descriptive statistics revealed 100% of participants understood all messages. When messages were evaluated individually, a minimum of 78% felt each message motivated activity and 67% said lengths were perfect. Findings identified messages that were relevant and potentially motivational to stimulate physical activity among this population.

Formative research to identify community partnerships and foster relationships for health promotion research in South Mississippi

OBJECTIVES

The purpose of this short communication is to describe the trust building and collaboration, fostering phases of a community-academic partnership between churches and academic researchers using a community-based participatory research approach.

STUDY DESIGN AND METHODS

An academic-community partnership with church leaders was initiated using survey administration and was further developed using focus groups. A coalition was developed, and it guided a subsequent focus group with church members.

RESULTS

Most churches surveyed did not have a health ministry in place but were agreeable that a variety of health topics were appropriate for the church setting. Church leaders felt that church members were key to engage in health programs in the church, whereas church members viewed pastoral support as important. Church leaders felt that working with a university brings credibility to their own health programs.

CONCLUSION

This early work provides a valuable example of how community collaborations may be initiated and developed using formative research methods, serving both community and research agendas.

The Church Bridge Project: An Academic-Community Perspective of a Church-Based Weight Management Pilot Intervention among Young Adult African Americans

BACKGROUND

Churches are effective community partners and settings to address weight management among African Americans. There is limited information on the use of churches to reach young adult populations and church collaborations with primary care clinics.

OBJECTIVES

The Church Bridge Project represents a community-academic partnership that presents the recruitment process of a church-based weight management intervention and describes baseline data of participants recruited from churches and primary care providers. We also discuss research contributions, challenges and limitations, study applicability, and practice implications from an academic and community perspective.

METHODS

Church leaders were involved in the entire research process. The theory-driven intervention included 12 diabetes prevention program-adapted education and motivational interviewing (MI)-guided sessions. Participants were recruited through primary care providers and church leaders. Demographics, medical and weight history, stage of change for weight loss, social support, and self-efficacy for diet and physical activity, weight, and girth circumferences were measured. Baseline descriptive data were analyzed.

RESULTS

Of 64 potential participants, 42 (65.6%) were enrolled in the study and 16 (25.0%) completed baseline data collection. No participants were recruited through primary care providers. Recruited participants were similar to the target population except for being all obese and mostly female. The mean ± SD age of participants was 34.31 ± 8.86 years with most reporting having more than a high school education (n = 14 [87.5%]), individual yearly income of less than $59,000 (n = 12 [75.0%]), and been married or living with a partner (n = 9 [56.3%]). Most reported a history of hypertension and an immediate family history of diabetes and hypertension. Most participants were classified as class III obesity.

CONCLUSIONS

Young adults and primary care providers are difficult to engage in church-based interventions. Church leaders were comfortable with a collaborate model for decision making, but not an empower model. Churches remain a successful method to reach African Americans; however, more research is needed to motivate young adults to participate in health intervention research.

Community-Based Participatory Research to Promote Healthy Diet and Nutrition and Prevent and Control Obesity Among African-Americans: a Literature Review

INTRODUCTION

The literature on community-based participatory research (CBPR) approaches for promoting healthy diet and nutrition and preventing and controlling obesity in African-American communities was systematically reviewed as part of the planning process for new research.

METHODS

CBPR studies of diet, nutrition, and weight management among African-Americans were identified from 1989 through October 31, 2015, using PubMed and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) databases and MeSH term and keyword searches.

RESULTS

A total of 16 CBPR studies on healthy diet, nutrition, and weight management among African-Americans were identified; outcome evaluation results were available for all but two. Of the remaining 14 studies, 11 focused on adults, 1 on children, and 2 on both children and adults. Eight studies employed CBPR methods to address diet, nutrition, and weight management in church settings. Four had a cluster-randomized controlled design. Others had a pre-post test, quasi-experimental, or uncontrolled design. Only one study addressed four levels of the socioecological model; none addressed all five levels of the model. The studies identified in this review indicate that CBPR approaches can be effective for promoting healthy diet, nutrition, and weight management among African-American adults, but there is a need for additional studies with rigorous study designs that overcome methodologic limitations of many existing studies. There is only limited evidence for the effectiveness of CBPR approaches for promoting healthy eating and weight control among African-American children and adolescents.

CONCLUSION

To address health disparities, additional CBPR studies are needed to promote healthy diet, nutrition, and weight management in African-American communities. Of particular interest are multilevel CBPR studies that include interventions aimed at multiple levels of the socioecological model.

A Community-Driven Implementation of the Body and Soul Program in Churches in the Twin Cities, Minnesota, 2011-2014

Background

African Americans have high disease and death rates due to cancer and cardiovascular disease. Health promotion efforts to improve diet have the potential to reduce these rates.

Community Context

Given their importance in the community and the extent of their reach, churches are effective avenues for health promotion efforts targeting African Americans. The objectives of this project were to promote healthy eating among African American church members, engage African American churches in the implementation of Body and Soul (an evidenced-based program that encourages healthy eating), and implement the program in the community with minimal resources.

Methods

From 2011 through 2014 we conducted a community engagement project to implement the 12-week Body and Soul program, which includes demonstrations of healthy recipes and peer counseling, in 20 churches. Participants (n = 310) completed baseline and follow-up surveys on their eating habits and experience with peer counseling. Church coordinators (n = 11) completed a survey evaluating the program.

Outcome

Participants’ weekly servings of fruit (baseline, 4.3; follow-up, 5.4; P < .001) and vegetables (baseline, 4.5; follow-up, 5.3; P < .001) increased. Church coordinators reported enthusiasm about Body and Soul at their church, and 10 of 11 church coordinators indicated that their pastor encouraged members to attend Body and Soul events. Program success was promoted by engaging the pastor in program activities and by scheduling events soon after church services. Implementation challenges were variation in peer counseling among churches and low turnout at follow-up events.

Interpretation

The project was successfully implemented in the 20 churches, and increases in healthy eating were observed. This project demonstrated that Body and Soul can be implemented in communities with little funds or other resources.

Barriers, Motivations, and Preferences for Physical Activity Among Female African American Older Adults

According to the Centers for Disease Control and Prevention, less than 11% of adults more than the age of 65 meet the 2008 Physical Activity Guidelines for Americans. Among minority populations, only 5% of non-Hispanic Black older adults met the guidelines. Given our limited understanding of psychosocial and environmental factors that affect physical activity participation in these groups, the purpose of our focus groups was to investigate barriers, motivators, and preferences of physical activity for community-dwelling African American older adults. Three focus groups were conducted with female African American older adults (N = 20). Questions posed to each focus group targeted motivations and barriers toward physical activity as well as their preferences for physical activity. The motivations included perceived health benefits of physical activity, social support, and enjoyment associated with engagement in physical activity. Prominent barriers included time and physical limitations, peer pressure and family responsibilities, and weather and poor neighborhood conditions. Group activities involving a dance component and novel exercises such as tai-chi or yoga were preferred choices. These findings should be taken into consideration when designing and implementing research or community physical activity programs for female African American older adults.

Stage Validity of the Health Action Process Approach in African American Breast Cancer Survivors

The Health Action Process Approach (HAPA) has been applied in a number of populations because it proposes to overcome limitations from previous health behavior theories. However, it has yet to be applied to cancer survivors or racial/ethnic minorities. In this study, we examined the construct validity of the HAPA phase and stage algorithms in a sample of African American breast cancer survivors. A total of 259 African American breast cancer survivors (mean age = 54 years) participated in a Web-based survey that assessed sociodemographic and medical characteristics, physical activity, and HAPA constructs. Analysis of covariance was used to compare mean differences between HAPA phase/stage. Statistical significance was determined at p < 0.017 due to multiple comparisons. Phase and stage inconsistencies were observed for most constructs. However, adequate distinctions were made for motivational self-efficacy and intentions (i.e., P = I < A) by phase, and both action and coping planning (i.e., P < I < A) by stage. Our data indicate partial support of the HAPA algorithm to classify African American breast cancer survivors according to stage or phase. Modifying the staging algorithm or constructs are needed if stage- or phase-based interventions can be designed for this population.

Impact of Self-Preference Community Fitness Interventions in High-Risk African Americans

African Americans have a high prevalence of obesity and physical inactivity, but few interventions have been successful in the long term. We describe a 1-year intervention program to increase physical activity and reduce cardiometabolic risk. Interventions incorporated the premise that self-selection into flexible venues and varying exercise modalities would result in improvement in fitness and risk factors. Results of this single-group pretest/posttest observational study show 1-year overall group reductions in body weight and body mass index and cardiometabolic factors including high-sensitivity C-reactive protein, and increases in dual-energy x-ray absorptiometry-derived absolute and percent lean mass and lean-fat ratio, and decreased fat mass.

Recommendations of Common Data Elements to Advance the Science of Self-Management of Chronic Conditions

PURPOSE

Common data elements (CDEs) are increasingly being used by researchers to promote data sharing across studies. The purposes of this article are to (a) describe the theoretical, conceptual, and definition issues in the development of a set of CDEs for research addressing self-management of chronic conditions; (b) propose an initial set of CDEs and their measures to advance the science of self-management; and (c) recommend implications for future research and dissemination.

DESIGN AND METHODS

Between July 2014 and December 2015 the directors of the National Institute of Nursing Research (NINR)-funded P20 and P30 centers of excellence and NINR staff met in a series of telephone calls and a face-to-face NINR-sponsored meeting to select a set of recommended CDEs to be used in self-management research. A list of potential CDEs was developed from examination of common constructs in current self-management frameworks, as well as identification of variables frequently used in studies conducted in the centers of excellence.

FINDINGS

The recommended CDEs include measures of three self-management processes: activation, self-regulation, and self-efficacy for managing chronic conditions, and one measure of a self-management outcome, global health.

CONCLUSIONS

The self-management of chronic conditions, which encompasses a considerable number of processes, behaviors, and outcomes across a broad range of chronic conditions, presents several challenges in the identification of a parsimonious set of CDEs. This initial list of recommended CDEs for use in self-management research is provisional in that it is expected that over time it will be refined. Comment and recommended revisions are sought from the research and practice communities.

CLINICAL RELEVANCE

The use of CDEs can facilitate generalizability of research findings across diverse population and interventions.

Reduced Prevalence of Obesity in 14 Disadvantaged Black Communities in the United States: A Successful 4-Year Place-Based Participatory Intervention

OBJECTIVES

To assess the impact of a large-scale place-based intervention on obesity prevalence in Black communities.

METHODS

The Racial and Ethnic Approaches to Community Health across the United States (REACH US) project was conducted in 14 predominantly Black communities in California, Illinois, Massachusetts, New York, Ohio, Pennsylvania, South Carolina, Virginia, Washington, and West Virginia. We measured trends from 2009 to 2012 in the prevalence of obesity. We used Behavioral Risk Factor Surveillance System data to compare these trends with trends among non-Hispanic Whites and non-Hispanic Blacks in the United States and in the 10 states where REACH communities were located, and with a propensity score-matched national sample of non-Hispanic Blacks.

RESULTS

The age-standardized prevalence of obesity decreased in REACH US communities (P = .045), but not in the comparison populations (P = .435 to P = .996). The relative change was -5.3% in REACH US communities versus +2.4% in propensity score-matched controls (P value for the difference = .031). The net effect on the reduction of obesity prevalence was about 1 percentage point per year for REACH.

CONCLUSIONS

Obesity prevalence was reduced in 14 disadvantaged Black communities that participated in the REACH project.

The Effect of Changes in Health Beliefs Among African-American and Rural White Church Congregants Enrolled in an Obesity Intervention: A Qualitative Evaluation

Church interventions can reduce obesity disparities by empowering participants with knowledge and skills within an established community. The purpose of this study was to evaluate the Biomedical/Obesity Reduction Trial (BMORe) and investigate changes in health beliefs among obese adult participants. Ten pre-/post-intervention focus groups applying the Health Belief Model conducted in two African-American churches in Tennessee (n = 20) and South Carolina (n = 20), and one rural Appalachian church in Kentucky (n = 21). Two independent coders using NVivo analyzed transcribed audio data and notes. Participants' health status of being overweight/obese and having comorbidities of diabetes and high blood pressure motivated enrollment in BMORe. Initially participants voiced low self-efficacy in cooking healthy and reading food labels. BMORe made participants feel "empowered" after 12 weeks compared to initially feeling "out of control" with their weight. Participants reported improvements in emotional health, quality of life, and fewer medications. During post-intervention focus groups, participants reported increased self-efficacy through family support, sharing healthy eating strategies, and having accountability partners. Solidarity and common understanding among BMORe participants led focus group attendees to comment how their peers motivated them to stay in the program for 12 weeks. Long-term barriers include keeping the weight off by maintaining habits of exercise and healthy eating. Implementation of pre-/post-intervention focus groups is an innovative approach to evaluate an obesity intervention and track how changes in health beliefs facilitated behavior change. This novel approach shows promise for behavioral interventions that rely on participant engagement for sustained effectiveness.

Moderators of intervention dose effects on diet quality and physical activity changes in a church-based, multicomponent, lifestyle study: Delta Body and Soul III

Many community-based lifestyle interventions targeting African Americans have reported positive effects on participants' dietary choices and physical activity habits. However, these effects vary and not all participants will have outcome changes. Moderation analysis can help explain differential effects observed, but are not often reported. Hence, the objective of this secondary analysis was to explore potential moderators of intervention dose effects on diet quality and physical activity outcomes in an effective lifestyle intervention. Delta Body and Soul III, conducted from 2011 to 2012, was a 6-month, church-based, multicomponent, educational intervention designed to improve diet quality and increase physical activity in rural Southern African American adults. Generalized linear mixed models were used to determine associations among indicators of intervention dose received by participants, potential moderators and health outcome changes. Results indicated only three baseline characteristics-employment status, food shopping frequency and individual with primary responsibility for meal preparation-moderated the effects of education session attendance on diet quality changes. No evidence for moderation of exercise class attendance effects on physical activity changes was found. Thus, this culturally targeted, multicomponent lifestyle intervention did induce positive health changes in participants with a range of sociodemographic characteristics and food shopping and eating behaviors.

Dyslipidemia in Special Ethnic Populations

This article reviews racial/ethnic differences in dyslipidemia-prevalence of dyslipidemia, its relation to coronary heart disease (CHD) and stroke mortality rates, response to lipid-lowering agents, and lifestyle modification. Asian Indians, Filipinos, and Hispanics are at higher risk for dyslipidemia, which is consistent with the higher CHD mortality rates in these groups. Statins may have greater efficacy for Asians, but the data are mixed. Lifestyle modifications are recommended. Culturally-tailored prevention and intervention should be provided to the minority populations with elevated risk for dyslipidemia and considerably more research is needed to determine the best approaches to helping specific subgroups.

A review of community-based participatory research studies to promote physical activity among African Americans

BACKGROUND

As part of the planning process for new research, the literature on community-based participatory research (CBPR) approaches for promoting physical activity in African American communities was systematically reviewed.

METHODS

Studies published through October 31, 2015 that employed CBPR methods were identified using PubMed and CINAHL databases and MeSH terms and keyword searches.

RESULTS

A total of 15 studies met the search criteria. One focused on CBPR and physical activity among African American school children and adolescents, 13 on adults, and one on both children and adults. Seven studies employed CBPR methods to promote physical activity in church settings. Eight of the studies had a pre-/post-test design, three had a quasi-experimental design, three had a randomized controlled design, and one was a case study.

CONCLUSIONS

Additional CBPR studies and faith-based interventions are needed to identify effective ways to promote physical activity in African American communities to address health disparities. Of particular interest are those that have an adequate sample size and a rigorous design, to overcome limitations of previous studies.

Assessing the usefulness of systematic reviews for policymakers in public health: A case study of overweight and obesity prevention interventions

OBJECTIVE

Systematic reviews (SRs) should include policy-relevant information in order to more readily inform policy and practice. We investigated whether SRs of overweight and obesity prevention interventions are framed in such a way that maximises their usefulness for policymakers.

METHOD

We conducted a systematic review of SRs of overweight and obesity prevention interventions published in 4 databases any time up to December 2014. We analysed the SRs for their usefulness to policymakers, using a coding frame developed based on literature around what policymakers want and need from systematic reviews. Systematic reviews were assessed for a) policy links and framing; b) quality assessment and conflict of interest statements: and c) discussion of policy implications.

RESULTS

Of the 153 SRs that met the inclusion criteria, very few (7%) had authors from policy-based organisations, 48% had funding from such organisations, and almost a third (31%) framed their introduction or aims around policy. Most (69%) discussed issues affecting generalisability of the SR findings but only a quarter (24%) discussed cost or cost-effectiveness of the intervention under investigation. Less than a third (29%) of SRs discussed the policy implications of their findings. SRs that were policy-framed were significantly more likely to discuss costs (PR=1.8, 95%CI 1.0-3.0) and policy implications (PR=2.5, 95%CI 1.5-4.0).

CONCLUSION

SRs should discuss the policy and practice implications of their findings to maximise the influence of SRs on policy making. It is recommended that SR guidelines are updated to include generalisability and discussion of policy and practice implications as a requirement.

Body image and weight control in South Africans 15 years or older: SANHANES-1

BACKGROUND

South African studies have suggested that differences in obesity prevalence between groups may be partly related to differences in body image and body size dissatisfaction. However, there has never been a national study that measured body image and its relationship to weight control in the country. Hence, the main aim of the study was to examine body image in relation to body mass index and weight control in South Africa.

METHODS

A cross-sectional survey and a secondary analyses of data were undertaken for 6 411 South Africans (15+ years) participating in the first South African National Health and Nutrition Examination Survey. Body image was investigated in relation to weight status and attempts to lose or gain weight. Data were analysed using STATA version 11.0. Descriptive statistics are presented as counts (numbers), percentages, means, standard error of means, and 95 % confidence intervals. Any differences in values were considered to be significantly different if the confidence intervals did not overlap.

RESULTS

Overall, 84.5 % participants had a largely distorted body image and 45.3 % were highly dissatisfied about their body size. Overweight and obese participants under estimated their body size and desired to be thinner. On the other hand, normal- and under-weight participants over estimated their body size and desired to be fatter. Only 12.1 and 10.1 % of participants attempted to lose or gain weight, respectively, mainly by adjusting dietary intake and physical activity.

DISCUSSION

Body mass index appears to influence body image and weight adjustment in South Africa.

CONCLUSIONS

South Africans at the extreme ends of the body mass index range have a largely distorted body image and are highly dissatisfied by it. This suggests a need for health education and beneficial weight control strategies to halt the obesity epidemic in the country.

The relationship between interviewer-respondent race match and reporting of energy intake using food frequency questionnaires in the rural South United States

Objective

The purpose of the observational study was to determine whether interviewer race influences food frequency questionnaire (FFQ) reporting accuracy in a Deep South, largely African American cohort.

Methods

A secondary analysis was conducted to investigate the influence of interviewer race on energy reporting of 319 African Americans who participated in the Mississippi Communities for Healthy Living intervention in May–June 2011, a community-based and USDA-funded project. Reported energy intake was compared to total energy expenditure to identify normal (ENR), under-(EUR) and over-reporters (EOR). Multivariate logistic regression models determined the relationship between race match and energy misreporting, accounting for confounding variables (educational level, health status perception, BMI, gender, and age) identified using chi-square/correlation analyses.

Results

The sample included 278 African Americans with 165 EURs, 26 EORs, and 87 ENRs identified. Logistic regression analyses revealed that there was no relationship between race-matched participants and EUR or EOR; controlling factors, BMI and perceived health status were significant in the model.

Conclusion

This study is the first to our knowledge to examine whether race influences dietary intake reporting which may influence assessment data used for comparison with health outcomes. This may have important implications for research conducted in health disparate populations, particularly rural, Southern populations.

•

We identify prevalence of misreporting of energy intake in an African American population.

•

We examine interviewer–respondent race match influence on energy reporting accuracy.

•

Energy underreporting was more predominant than overreporting.

•

Interviewer–respondent race match did not influence energy reporting.

Dyslipidemia in special ethnic populations

This article reviews racial/ethnic differences in dyslipidemia-prevalence of dyslipidemia, its relation to coronary heart disease (CHD) and stroke mortality rates, response to lipid-lowering agents, and lifestyle modification. Asian Indians, Filipinos, and Hispanics are at higher risk for dyslipidemia, which is consistent with the higher CHD mortality rates in these groups. Statins may have greater efficacy for Asians, but the data are mixed. Lifestyle modifications are recommended. Culturally-tailored prevention and intervention should be provided to the minority populations with elevated risk for dyslipidemia and considerably more research is needed to determine the best approaches to helping specific subgroups.

A community-based walking program to promote physical activity among African American women

The death rate from cardiovascular disease (CVD) is substantially higher among African American women than for white women. Physical activity has been linked to decreased risk factors and deaths related to CVD. Despite the health benefits of physical activity, reports show most African American women have low levels of physical activity. Home- or community-based walking interventions are effective strategies to promote increased levels of physical activity among African American women. This article describes the implementation of one such program.

Reducing cardiovascular disease risk in mid-life and older African Americans: a church-based longitudinal intervention project at baseline

INTRODUCTION

African Americans (AAs) experience higher age-adjusted morbidity and mortality than Whites for cardiovascular disease (CVD). Church-based health programs can reduce risk factors for CVD, including elevated blood pressure [BP], excess body weight, sedentary lifestyle and diet. Yet few studies have incorporated older adults and longitudinal designs.

PURPOSES

The aims of this study are to: a) describe a theory-driven longitudinal intervention study to reduce CVD risk in mid-life and older AAs; b) compare selected dietary (fruit and vegetable servings/day, fat consumption), physical activity (PA) and clinical variables (BMI, girth circumferences, systolic and diastolic BP, LDL, HDL, total cholesterol [CHOL] and HDL/CHOL) between treatment and comparison churches at baseline; c) identify selected background characteristics (life satisfaction, social support, age, gender, educational level, marital status, living arrangement and medication use) at baseline that may confound results; and d) share the lessons learned.

METHODS

This study incorporated a longitudinal pre/post with comparison group quasi-experimental design. Community-based participatory research (CBPR) was used to discover ideas for the study, identify community advisors, recruit churches (three treatment, three comparison) in two-counties in North Florida, and randomly select 221 mid-life and older AAs (45+) (n=104 in clinical subsample), stratifying for age and gender. Data were collected through self-report questionnaires and clinical assessments.

RESULTS AND CONCLUSIONS

Dietary, PA and clinical results were similar to the literature. Treatment and comparison groups were similar in background characteristics and health behaviors but differed in selected clinical factors. For the total sample, relationships were noted for most of the background characteristics. Lessons learned focused on community relationships and participant recruitment.
