Purpose of the Study: Lay health educators (LHEs) offer great promise for facilitating the translation of evidence-based health promotion programs to underserved areas; yet, there is little guidance on how to train LHEs to implement these programs, particularly in the crucial area of empirically validated obesity interventions., Design and Methods: This article describes experiences in recruiting, training, and retaining 20 LHEs who delivered a 12-month evidence-based behavioral lifestyle intervention (based on the Diabetes Prevention Program) in senior centers across a rural state. A mixed method approach was used which incorporated collecting the folllowing: quantitative data on sociodemographic characteristics of LHEs; process data related to training, recruitment, intervention implementation, and retention of LHEs; and a quantitative program evaluation questionnaire, which was supplemented by a qualitative program evaluation questionnaire. Descriptive statistics were calculated for quantitative data, and qualitative data were analyzed using content analysis., Results: The training program was well received, and the LHEs effectively recruited participants and implemented the lifestyle intervention in senior centers following a structured protocol., Implications: The methods used in this study produced excellent long-term retention of LHEs and good adherence to intervention protocol, and as such may provide a model that could be effective for others seeking to implement LHE-delivered health promotion programs.

Introduction: Older adults could benefit from public health interventions that address the health conditions they face. However, translation of evidence-based interventions into the community has been slow. We implemented 2 evidence-based interventions delivered by lay health educators in Arkansas senior centers from 2008 to 2011: a behavioral weight loss intervention and a memory improvement intervention. The objective of this study was to measure the ability of these programs to reach and serve the growing population of older Americans. We report on differences in program enrollment by age, sex, race, and ethnicity and suggest how our approach to calculating the reach of the 2 interventions can guide future research and program development., Methods: We defined the reach of the 2 interventions as the proportion of people who needed the intervention and responded to initial recruitment efforts but who did not enroll compared with the proportion of people who needed the intervention and actually enrolled in the program. To calculate these proportions, we used Reach, Efficacy/Effectiveness, Adoption, Implementation, and Maintenance framework formulas. We defined need as the prevalence of obesity (body mass index in kg/m2 ≥30) and the level of concern about memory problems among older adults aged 60 years or older. Our target population was 2,198 people aged 60 years or older who attend 15 senior centers in Arkansas., Results: More than half of our target population responded to recruitment efforts for the behavioral weight loss intervention (61.9%) and for the memory improvement intervention (58.1%), yielding an overall response rate of 59.7%. More than one-third (35.6%) of the target population enrolled in the behavioral weight loss intervention, and 22.8% enrolled in the memory improvement intervention, for an overall reach for the 2 programs of 27.9%., Conclusion: The reach of 2 evidence-based interventions designed for older adults that targeted specific health conditions and that were delivered in senior centers by community members was high. Our approach to calculating reach in applied settings can guide future research and program development.

Background: Older adults have high obesity rates and respond well to evidence-based weight-loss programs, such as the Diabetes Prevention Program (DPP) Lifestyle intervention. The goal of this study was to determine whether a translation of the DPP Lifestyle program delivered by lay health educators and conducted in senior centers is effective in promoting weight loss among older adults., Design: An RCT with older adults nested within senior centers. Senior centers identified lay health educators to receive training and deliver the intervention program at the senior center. Senior centers were randomized to DPP Lifestyle program or an attention control intervention (cognitive training)., Setting/participants: Senior centers (N=15) located throughout Arkansas. Participants (N=228) were obese (BMI=34.5±4.9) older (aged 71.2±6.6 years) adults able to engage in moderate exercise. Follow-up data were collected at 4 months on 93% of the original cohort between February 2009 and July 2010., Interventions: A 12-session translation of the Diabetes Prevention Program Lifestyle behavioral weight-control program delivered in group sessions by trained lay health educators., Main Outcome Measures: Body weight was assessed by digital scale. Percentage weight loss from baseline and proportion achieving ≥5% and ≥7% weight loss were examined. Analyses were completed in March 2011., Results: Participants attending senior centers randomized to Lifestyle lost a significantly greater percentage of baseline weight (3.8%, 95% CI=2.9%, 4.6%) than those in the control senior centers (0.2%, 95% CI= -0.6%, -0.9%) after adjusting for baseline BMI and gender (p<0.001). Among participants attending senior centers offering the Lifestyle program, 38% lost ≥5% of baseline weight compared with 5% in the control arm (p<0.001). Similarly, significantly more participants (24%) in Lifestyle senior centers lost ≥7% than did control participants (3%, p=0.001)., Conclusions: A behavioral lifestyle weight-loss intervention delivered by a lay health educator offers a promising vehicle for translation of evidence-based obesity treatment programs in underserved areas., Trial Registration: This study is registered at Clinicaltrials.govNCT01377506., (Copyright © 2011 American Journal of Preventive Medicine.

Collaboratively, the nutritional health problems of the Lower Mississippi Delta (LMD) region were examined and opportunities identified for conducting research interventions. To combat the nutritional health problems in the LMD, community residents yielded to a more comprehensive and participatory approach known as community-based participatory research (CBPR). Community residents partnered with academic researchers and other organizational entities to improve the overall quality of diet and health in their respective communities using CBPR. The collaborative work in the LMD focused on interventions conducted in each of three specific communities across three states: Marvell, Arkansas (Marvell NIRI), and its surrounding public school district; Franklin Parish in Louisiana (Franklin NIRI); and the city of Hollandale, Mississippi (Hollandale NIRI). This paper examined some of the research interventions conducted in Franklin, Hollandale, and Marvell NIRI respectively, how leadership emerged from each of these communities, and lessons learned as a result of the CBPR model.

Since its inception, capacity building has been a stated goal of the Delta Nutrition Intervention Research Initiative, a tri-state collaboration in the Lower Mississippi Delta to address high rates of chronic disease. Textual analysis of project documents identifies and describes strategies carried out to foster capacity building. Strategies to build community capacity include fostering participation, cultivating leadership opportunities, training community members as co-researchers, securing community resources, and implementing the intervention together. Incorporating capacity-building approaches in health promotion and nutrition-intervention programming in rural communities provides a means to enhance potential for sustainability of health outcomes and developed effectiveness.

Objective: Measure relationships of locus of control and social support to diet changes in an intervention trial., Design: Participants in the Polyp Prevention Trial (PPT) completed Multidimensional Health Locus of Control (MHLC) and Norbeck Social Support Questionnaires (NSSQ) and modified Block food frequency questionnaires. Data were collected at baseline and 1 year later., Subjects/setting: A convenience sample of PPT intervention (N = 68) and control (n = 43) participants at 1 clinical center participated in this ancillary study., Main Outcome Measures: Mean daily dietary intakes after 1 year were compared with baseline values. Intervention participants' scores for MHLC internal locus of control and NSSQ total functional network were correlated with diet changes., Statistical Analyses Performed: Group percentages were compared using the Fisher exact test; means were compared by t test., Results: Groups were comparable in demographics, baseline diet, and scores for internal locus of control and total functional network. Intervention group participants made greater diet changes than control participants in intake of fat (-27 g vs -8 g), fat as a percentage of kilocalories (-8% vs -2%), fiber as grams per 1,000 kcal (7 g vs 0.3 g), and daily fruit/vegetable servings (2.0 vs 0.2). Pearson correlations of diet changes with internal locus of control scores (all P > .05) were fat grams, r = 0.031; fat as percentage of kilocalories, r = 0.023; fiber grams per 1,000 kcal; r = 0.230; and fruit/vegetable servings, r = 0.186. Correlations with total functional network scores were: fat grams, r = 0.022 (P > .05); fat as percentage of kilocalories, r = -0.108 (P > .05); fiber grams per 1,000 kcal, r = 0.276, P < .05; and daily fruit/vegetable servings, r = 0.326, P < .05., Applications/conclusions: Intensive and skillful dietary intervention can succeed whether or not clients bring strong internal locus of control or social support to the diet change program.

Objective: Rural black communities bear a disproportionate burden of obesity. To increase reach among underserved groups, community-based weight loss and maintenance interventions are crucial.Methods: The Diabetes Prevention Program (DPP) was adapted for rural black adults of faith to create The Wholeness, Oneness, Righteousness, Deliverance (WORD) trial, a group-based, community health worker-delivered weight loss intervention. A Weight Loss Only arm (16 sessions) was compared with a Weight Loss + Maintenance arm (16 + 12 sessions) in a cluster randomized controlled trial of 31 churches (n = 440). Weight and related behaviors were assessed at 0, 6, 12, and 18 months.Results: The WORD produced weight loss from baseline to 6 months (percentage body weight change -2.47 [-3.13 to -1.80]). Among those who lost 5% of their baseline weight, there was a statistical trend of lower weight regain in the Weight Loss + Maintenance arm compared with control. Maintenance arm participants reported higher activity at 12 months. There were no between-arm differences at 18 months.Conclusions: The WORD produced weight loss from baseline to 6 months on par with that produced by other DPP adaptations for black communities, including adaptations using health professionals. Weight regain was also consistent with that reported in prior literature. Continuing sessions as part of the church's mission may foster adoption of DPP-based weight loss programs.

Senior centers are ideal locations to deliver evidence-based health promotion programs to the rapidly growing population of older Americans to help them remain healthy and independent in the community. However, little reported research is conducted in partnership with senior centers; thus, not much is known about barriers and facilitators for senior centers serving as research sites. To fill this gap and potentially accelerate research within senior centers to enhance translation of evidence-based interventions into practice, the present study examined barriers and facilitators of senior centers invited to participate in a cluster-randomized controlled trial. Primary barriers to participation related to staffing and perceived inability to recruit older adult participants meeting research criteria. The primary facilitator was a desire to offer programs that were of interest and beneficial to seniors. Senior centers are interested in participating in research that provides benefit to older adults but may need assistance from researchers to overcome participation barriers.

Most faith-based obesity intervention research has been conducted in African-American Protestant churches. However, Catholic communities might also benefit from a faith-tailored approach. Overweight Catholic individuals (n = 34, 71% female) were randomized to a Catholic-tailored or standard behavioral 16-week group weight control program. Both conditions experienced significant weight losses (Catholic-tailored: -8.1 + 4.1%, Standard: -7.9 + 4.2%); however, treatment satisfaction was significantly greater in the Catholic-tailored program. The Catholic-tailored program experienced trends for greater attendance, more completed self-monitoring journals, and smaller weight regain six months post-treatment than the standard program. Catholic-tailored programs may represent a feasible, culturally acceptable and effective approach to weight loss/maintenance in this faith community. [ABSTRACT FROM AUTHOR]

Purpose: There is minimal information regarding the Reach and Adoption of evidence-based weight loss maintenance interventions for African Americans of faith.Design: The WORD (Wholeness, Oneness, Righteousness, Deliverance) was an 18-month, cluster randomized trial designed to reduce and maintain weight loss in African American adults of faith. Participants received the Diabetes Prevention Program adapted core weight loss program for 6 months, and churches were subsequently randomized to 12-month maintenance treatment or control. All participants underwent body weight and associated behavioral and psychosocial assessments at baseline, 6, 12, and 18 months. The current article focuses on assessing Reach and Adoption at baseline and 6 months using the Reach, Effectiveness, Adoption, Implementation, and Maintenance framework.Setting: Lower Mississippi Delta.Participants: Thirty churches, 61 WORD Leaders (WLs), and 426 participants.Intervention: Group delivered by trained community members (WLs).Measures: Body mass index and percentage weight lost from baseline to 6-month follow-up were measured. Reach was assessed at participant, WL, and church levels through calculating participation rates and sociodemographics of each level. Adoption was assessed at church and WL levels.Analysis: Descriptive statistics summarized baseline characteristics of each level. Continuous and categorical end point comparisons were made.Results: Participants' participation rate was 0.84 (n = 437 agreed to participate, n = 519 eligible invited to participate); they were predominantly female, employed, and had a mean age of 49.8. Dropouts by 6 months were younger, had differential marital status, and religious attendance compared with retained participants. Church participation rate was 0.63 (n = 30 enrolled, n = 48 eligible approached) and the majority reported ≤100 active members. The WL participation rate was 0.61 (n = 61 implemented intervention, n = 100 eligible approached); they were primarily female and aged 53.9 (mean).Conclusion: Recruitment, engagement, and delivery strategies employed by the WORD show promise of sustained engagement and adoption in other faith-based behavioral weight management programs for African Americans.
