Relationship between adherence to diet and physical activity guidelines and self-efficacy among black women with high blood pressure

Abstract

Hypertension prevalence is highest among Black women in America. Understanding the relationship between adherence to diet and physical activity using socio-cognitive approaches (e.g. self-efficacy and social support) may be effective approaches in understanding hypertension management. This study found that dietary self-efficacy was associated with dietary adherence, and family social support was associated with both diet and physical activity self-efficacy. Social support mediated the relationship between dietary self-efficacy and dietary adherence. A paradoxical finding emerged where participants in the highest self-efficacy tertile also had higher measured systolic blood pressure. More research is necessary to explore culture-specific factors underlying hypertension treatment management among Black women.
