Using Complementary and Integrative Medicine to Treat High Blood Pressure in African Americans in the United States: Impact of Knowledge, Beliefs, Attitudes, and Behaviors

Background: African Americans have the highest prevalence of high blood pressure (HBP) in the United States, but the lowest blood pressure control rates among all major racial/ethnic groups. This study examined the extent to which African Americans use home remedies to treat HBP and assessed their knowledge, beliefs, attitudes, and behaviors regarding such use. Materials and Methods: This study utilized a descriptive, exploratory, cross-sectional, and correlational research design. We determined the association between knowledge, beliefs, attitudes, and behaviors and use of home remedies among participants using a principal investigator-developed online questionnaire entitled the Beliefs about Hypertension Survey (BHS). Results: Reliability for the BHS representing all four dependent variables was good (Cronbach's α = 0.848). The study sample was 254 African Americans with and without HBP (79.9% females; 83% aged 30-59). Participants were more willing to use home remedies to treat rather than to prevent HBP, with 58% of participants with HBP reporting current use of home remedies as treatment. Results of the Multivariate Analysis of Variance test indicated statistical significance (P50.000) only for the behavior variable (a50.05), with no significant differences found between participants with and without HBP with respect to knowledge, beliefs, and attitudes. Conclusion: The results suggest that diagnosis of HBP increases African Americans' willingness to use home remedies, but this group needs more education about the effects and risk factors of HBP. Further evidence-based studies will help to increase knowledge and acceptance of home remedies as a viable treatment option for HBP.
