| Popis: | Evidence of the effectiveness of community-based lifestyle behavior change interventions among African-American adults is mixed. We implemented a behavioral lifestyle change intervention, Heart Matters, in two rural counties in North Carolina with African-American adults. Our aim was to evaluate the effect of Heart Matters on dietary and physical activity behaviors, self-efficacy, and social support. We used a cluster randomized controlled trial to compare Heart Matters to a delayed intervention control group after 6 months. A total of 143 African-American participants were recruited and 108 completed 6-month follow-up assessments (75.5%). We used mixed regression models to evaluate changes in outcomes from baseline to 6-month follow-up. The intervention had a significant positive effect on self-reported scores of encouragement of healthy eating, resulting in an increase in social support from family of 6.11 units (95% CI [1.99, 10.22]) (p < .01). However, intervention participants also had an increase in discouragement of healthy eating compared to controls of 5.59 units (95% CI [1.46, 9.73]) among family (p < .01). There were no significant differences in changes in dietary behaviors. Intervention participants had increased odds (OR = 2.86, 95% CI [1.18, 6.93]) of increased frequency of vigorous activity for at least 20 min per week compared to control participants (p < .05). Individual and group lifestyle behavior counseling can have a role in promoting physical activity levels among rural African-American adults, but more research is needed to identify the best strategies to bolster effectiveness and influence dietary change.
