Abstract

INTRODUCTION: Hypertension is the leading modifiable risk factor for cardiovascular disease, and it disproportionately affects African American women, who face increased risks of heart disease, kidney disease, and stroke. The Dietary Approaches to Stop Hypertension (DASH) diet effectively reduces blood pressure, but African American women often face challenges with adhering to it. Peer support, a proven mechanism for improving health behaviors through social connections and community resources, may help these women better manage their diet and hypertension. This qualitative study explored the experiences of African American women participating in an eight-week peer (dyadic) support intervention to improve DASH diet adherence and lowering systolic blood pressure, with an emphasis on understanding the dyadic relationship.

METHODS: A purposive sample of 40 African American women (20 dyads) was recruited for five focus groups that were conducted both online and in person. Content analysis was used to identify themes related to the nature and quality of peer interactions and relationships from the perspectives of the 34 women who completed the intervention (Mean age = 71.38 years; SD = 8.38).

RESULTS: Four subthemes emerged: emotional support, shared experiences, informational/inspirational support, and accountability. The participants reported forming strong, supportive relationships that were crucial in improving diet and blood pressure management.

CONCLUSION: This study underscores the benefits of peer support in managing hypertension among older African American women, suggesting the need for future randomized controlled trials to examine the effectiveness of the DASH diet with and without peer support.
