The Effect of a Culturally Relevant Cardiovascular Health Promotion Program on Rural African Americans

Health disparities among rural African Americans include disproportionately higher morbidity and mortality rates associated with cardiovascular disease. Interventions designed to decrease cardiovascular risk can potentially improve health outcomes among rural, underserved communities. The purpose of this study was to test the effect of a cardiovascular health promotion intervention among rural African Americans. An experimental study randomized by church clusters was done in two rural counties in northern Florida. A total of 229 participants, 114 in the intervention group and 115 in the control group, were recruited from twelve rural African American churches. The pretest-posttest design included instruments chosen to measure cardiovascular health habits and knowledge as well as changes in produce consumption, dietary fat intake, and exercise using the major components of the Integrated Model of Behavioral Prediction: intentions, norms, attitudes, and self-efficacy. Linear mixed model was the statistical test used to detect the program effects. Participants who received the intervention had significant increases in scores for the cardiovascular health habits (p < .01) and health knowledge (p < .01) variables compared with the control group. There were also significant group differences regarding intentions to increase produce consumption (p < .01) and reduce dietary fat intake (p < .01). The cardiovascular health program was associated with other statistically significant results including produce consumption attitudes (p = .01) and norms (p < .01), dietary fat attitudes (p = .04) and norms (p < .01), and exercise attitudes (p < .01). There were also significant results found for perceived behavioral control/self-efficacy regarding increasing produce consumption (p < .01), reducing dietary fat intake (p = .03), and increasing exercise (p = .01). Compared to the control group, the cardiovascular health promotion intervention was effective in fostering positive health effects for most of the variables measured. The findings supported the theoretical framework used for guiding the study, the Integrative Model of Behavioral Prediction Nurse-led health promotion interventions within church settings can be effective means for reducing overall cardiovascular risk and health disparities among rural African American populations.
