RESUMO
African Americans (AAs) have higher prevalence of uncontrolled hypertension than Whites, which leads to reduced life expectancy. Barriers to achieving blood pressure control in AAs include mistrust of healthcare and poor adherence to medication and dietary recommendations. We conducted a pilot study of a church-based community health worker (CHW) intervention to reduce blood pressure among AAs by providing support and strategies to improve diet and medication adherence. To increase trust and cultural concordance, we hired and trained church members to serve as CHWs. AA adults (n = 79) with poorly controlled blood pressure were recruited from churches in a low-income, segregated neighborhood of Chicago. Participants had an average of 7.5 visits with CHWs over 6 months. Mean change in systolic blood pressure across participants was - 5 mm/Hg (p = 0.029). Change was greater among participants (n = 45) with higher baseline blood pressure (- 9.2, p = 0.009). Medication adherence increased at follow-up, largely due to improved timeliness of medication refills, but adherence to the DASH diet decreased slightly. Intervention fidelity was poor. Recordings of CHW visits revealed that CHWs did not adhere closely to the intervention protocol, especially with regard to assisting participants with action plans for behavior change. Participants gave the intervention high ratings for acceptability and appropriateness, and slightly lower ratings for feasibility of achieving intervention behavioral targets. Participants valued having the intervention delivered at their church and preferred a church-based intervention to an intervention conducted in a clinical setting. A church-based CHW intervention may be effective at reducing blood pressure in AAs.
RESUMO
West Side Alive (WSA) is a partnership among pastors, church members and health researchers with the goal of improving health in the churches and surrounding community in the West Side of Chicago, a highly segregated African American area of Chicago with high rates of premature mortality and social disadvantage. To inform health intervention development, WSA conducted a series of health screenings that took place in seven partner churches. Key measures included social determinants of health and healthcare access, depression and PTSD screeners, and measurement of cardiometabolic risk factors, including blood pressure, weight, cholesterol and hemoglobin A1C (A1C). A total of 1106 adults were screened, consisting of WSA church members (n = 687), members of the local community served by the church (n = 339) and 80 individuals with unknown church status. Mean age was 52.8 years, 57% were female, and 67% reported at least one social risk factor (e.g. food insecurity). Almost all participants had at least one cardiovascular risk factor (92%), including 50% with obesity, 79% with elevated blood pressure and 65% with elevated A1C. A third of participants experienced ≥ 4 potentially traumatic events and 26% screened positive for depression and/or post-traumatic stress disorder. Participants were given personalized health reports and referred to services as needed. Information from the screenings will be used to inform the design of interventions targeting the West Side community and delivered in partnership with the churches. Sharing these results helped mobilize community members to improve their own health and the health of their community.

Heart-to-Heart (H2H) is a church-based behavioral cluster randomized trial to measure the effectiveness of a lifestyle education program for reducing blood pressure (BP) in African American adults with uncontrolled BP. Design and implementation of this study were informed by our ALIVE pilot study conducted with church pastors and leaders using a community-based participatory research methodology. The current study employs a cross-over design in which all participants receive two 6-month programs in different orders: the intervention arm receives the H2H program first, followed by a financial education program, and the comparator arm receives the programs in the reverse order. Approximately 34 churches will be randomized with the aim of including at least 272 participants across churches. The H2H program consists of 24 weekly dietitian-led diet and lifestyle virtual education sessions, 12 Bible studies taught by the church pastor reinforcing positive dietary behaviors from a biblical perspective, daily self-monitoring of BP, and, as needed, one-on-one support from a community health worker to assist with medication adherence. The Money Smart program consists of 14 financial education sessions and 12 Bible studies teaching the biblical basis of good financial management over a 6-month period. The primary outcome measure is systolic BP at 6 months with a follow-up at 12 months. Secondary outcome measures include medication adherence, Dietary Approaches to Stop Hypertension (DASH) diet adherence, self-efficacy for hypertension self-care, social support for eating a healthy diet, hypertension and nutrition knowledge, beliefs about medicines, barriers to medication use, depression, and financial knowledge and behaviors.

BACKGROUND: A key intervention to address Black-White health disparities in cardiovascular disease (CVD) is to improve diet quality, especially vegetable consumption, among African Americans. However, effective and sustainable interventions are lacking for this population. OBJECTIVE: Conduct a proof-of-concept study to measure the feasibility of implementing and rigorously assessing a novel, culturally tailored church-based intervention to improve vegetable consumption and total diet quality among African Americans. METHODS: The study was designed and implemented by a community-based participatory research (CBPR) partnership between researchers, pastors, and church leaders. The Abundant Living in Vibrant Energy (ALIVE) intervention included a Bible study and small group-based nutrition education delivered by pastors and church members in 24 two-hour sessions over 9 months as well as church-wide activities. Overall, 206 people enrolled across five African American churches. RESULTS: Participants attended 56% of sessions. The mean number of daily vegetable servings at baseline was 3.04; this increased by one serving at the 9-month follow-up (p < .001). Vegetable servings increased by more than one in 47% of participants. Total diet quality also increased (p < .01) and significant reductions were found in weight (-1.0 kg; p < .001), systolic blood pressure (-3.91 mm Hg; p = .002), and diastolic blood pressure (-2.18 mm Hg; p = .001). CONCLUSIONS: The ALIVE intervention was flexibly adapted by a range of churches; successfully implemented by pastors, deacons, and church leaders; and rigorously evaluated across a range of church settings. Further study of this intervention is warranted given the evidence for potential efficacy and a high level of external validity.
