Randomized trial of a behavioral weight loss intervention for low-income women: the Weight Wise Program.

Low‐income women in the United States have the highest rates of obesity, yet they are seldom included in weight loss trials. To address this research gap, components of two evidence‐based weight loss interventions were adapted to create a 16‐week intervention for low‐income women (Weight Wise Program), which was evaluated in a randomized trial with the primary outcome of weight loss at 5‐month follow‐up. Participants were low‐income women (40–64 years) with a BMI of 25–45. Of 143 participants, 72 were randomized to the Weight Wise Program (WWP) and 71 to the Control Group (CG). Five‐month follow‐up data were obtained from 64 (89%) WWP and 62 (87%) CG participants. With baseline values carried forward for missing data, WWP participants had a weight change of −3.7 kg compared to 0.7 kg in the CG (4.4 kg difference, 95% confidence interval (CI), 3.2–5.5, P < 0.001). For systolic blood pressure (SBP), change in the WWP was −6.5 mm Hg compared to −0.4 mm Hg among controls (6.2 mm Hg difference, 95% CI, 1.7–10.6, P = 0.007); for diastolic BP (DBP), changes were −4.1 mm Hg for WWP compared to −1.3 mm Hg for controls (2.8 mm Hg difference, 95% CI, 0.0–5.5, P = 0.05). Of the 72 WWP participants, 64, 47, and 19% lost at least 3, 5, and 7% of their initial body weight, respectively. In conclusion, the WWP was associated with statistically significant and clinically important short‐term weight loss.

The heart healthy lenoir project-an intervention to reduce disparities in hypertension control: study protocol

BackgroundRacial disparities in blood pressure control are well established; however the impact of low health literacy (LHL) on blood pressure has garnered less attention. Office based interventions that are created with iterative patient, practice and community stakeholder input and are rolled out incrementally, may help address these disparities in hypertension control. This paper describes our study protocol.Methods/designUsing a community based participatory research (CBPR) approach, we designed and implemented a cohort study that includes both a practice level and patient level intervention to enhance the care and support of patients with hypertension in primary care practices in a rural region of eastern North Carolina. The study is divided into a formative phase and an ongoing 2.5 year implementation phase. Our main care enhancement activities include the integration of a community health coach, using home blood pressure monitoring in clinical decision making, standardizing care delivery processes, and working to improve medication adherence. Main outcomes include overall blood pressure change, the differential change in blood pressure by race (African American vs. White) and health literacy level (low vs. higher health literacy).DiscussionUsing a community based participatory approach in primary care practice settings has helped to engage patients and practice staff and providers in the research effort and in making practice changes to support hypertension care. Practices have engaged at varying levels, but progress has been made in implementing and iteratively improving upon the interventions to date.Trial registrationClinicalTrials.gov NCT01425515.

Rationale, design, and sample characteristics of a practical randomized trial to assess a weight loss intervention for low-income women: The Weight-Wise II Program

Obesity is common among low-income mid-life women, yet most published weight loss studies have not focused on this population and have been highly resourced efficacy trials. Thus, practical type 2 translational studies are needed to evaluate weight loss interventions for low-income women. In this paper, we present the rationale, study design, and baseline characteristics of a type 2 translational study that evaluates both the processes and outcomes of a weight loss intervention for low-income women given at 6 county health departments in North Carolina. Key features of this study include random selection of study sites, intervention delivery by current staff at study sites, efforts to integrate the intervention with local community resources, a focus on evaluating the processes of translation using the RE-AIM framework, use of an evidence-based weight loss intervention, a detailed description of participant recruitment and representativeness, and a practical randomized trial designed to assess the effectiveness of the intervention. Of 81 health departments invited to participate, 30 (37%) were eligible and willing, and 6 were selected at random to deliver the intervention. Of 432 potential participants screened by phone, 213 (49%) were eligible and of these, 189 (89%) completed baseline measures and were randomized to receive a 5-month weight loss intervention or a delayed intervention. The mean age was 51, mean BMI 37 kg/m(2), 53% were African American, and 43% had no health insurance. The results of this study should be informative to key stakeholders interested in real world weight loss interventions for low-income mid-life women.

Cost-effectiveness of a behavioral weight loss intervention for low-income women: the Weight-Wise Program.

OBJECTIVE Assess the cost-effectiveness of a 16-week weight loss intervention (Weight-Wise) for low-income midlife women. METHOD A randomized controlled trial conducted in North Carolina in 2007 tested a weight loss intervention among 143 women (40-64 years old, mean BMI=35.1 kg/m(2)). Women were randomized to one of two arms-special intervention (n=72) and a wait-listed control group (n=71). Effectiveness measures included changes in weight, systolic and diastolic blood pressure, total cholesterol, and HDL cholesterol. Cost-effectiveness measures calculated life years gained (LYG) from changes in weight, based on excess years life lost (YLL) algorithm. RESULTS Intervention participants had statistically significant decreases in weight (kg) (-4.4 95% CI=-5.6, -3.2) and in systolic blood pressure (-6.2 mm Hg, 95% CI=-10.6, -1.7) compared to controls. Total cost of conducting Weight-Wise was

Extending the Reach of Public Health Nutrition: Training Community Practitioners in Multilevel Approaches

Background Heart Healthy Lenoir is a transdisciplinary project aimed at creating long-term, sustainable approaches to reduce cardiovascular disease risk disparities in Lenoir County, North Carolina using a design spanning genomic analysis and clinical intervention. We hypothesized that residents of Lenoir County would be unfamiliar and mistrustful of genomic research, and therefore reluctant to participate; additionally, these feelings would be higher in African-Americans. Methodology To test our hypothesis, we conducted qualitative research using community-based participatory research principles to ensure our genomic research strategies addressed the needs, priorities, and concerns of the community. African-American (n = 19) and White (n = 16) adults in Lenoir County participated in four focus groups exploring perceptions about genomics and cardiovascular disease. Demographic surveys were administered and a semi-structured interview guide was used to facilitate discussions. The discussions were digitally recorded, transcribed verbatim, and analyzed in ATLAS.ti. Results and Significance From our analysis, key themes emerged: transparent communication, privacy, participation incentives and barriers, knowledge, and the impact of knowing. African-Americans were more concerned about privacy and community impact compared to Whites, however, African-Americans were still eager to participate in our genomic research project. The results from our formative study were used to improve the informed consent and recruitment processes by: 1) reducing misconceptions of genomic studies; and 2) helping to foster participant understanding and trust with the researchers. Our study demonstrates how community-based participatory research principles can be used to gain deeper insight into the community and increase participation in genomic research studies. Due in part to these efforts 80.3% of eligible African-American participants and 86.9% of eligible White participants enrolled in the Heart Healthy Lenoir Genomics study making our overall enrollment 57.8% African-American. Future research will investigate return of genomic results in the Lenoir community.

Characterizing Community Health Workers on Research Teams: Results From the Centers for Population Health and Health Disparities.

Introduction Patient and practice perspectives can inform development of team-based approaches to improving blood pressure control in primary care. We used a community-based participatory research approach to assess patient and practice perceptions regarding the value of team-based strategies for controlling blood pressure in a rural North Carolina population from 2010 through 2012. Methods In-depth interviews were conducted with 41 adults with hypertension, purposely sampled to include diversity of sex, race, literacy, and blood pressure control, and with key office staff at 5 rural primary care practices in the southeastern US “stroke belt.” Interviews explored barriers to controlling blood pressure, the practice’s role in controlling blood pressure, and opinions on the use of team care delivery. Results Patients reported that provider strategies to optimize blood pressure control should include regular visits, medication adjustment, side-effect discussion, and behavioral counseling. When discussing team-based approaches to hypertension care, patients valued verbal encouragement, calls from the doctor’s office, and the opportunity to ask questions. However, they voiced concerns about the effect of having too many people involved in their care. Practice staff focused on multiple, broad methods to control blood pressure including counseling, regular office visits, media to improve awareness, and support groups. An explicit focus of delivering care as teams was a newer concept. Conclusion When developing a team approach to hypertension treatment, patients value high-quality communication and not losing their primary relationship with their provider. Practice staff members were open to a team-based approach but had limited knowledge of what such an approach would entail.
