Psychosocial Determinants of Recommended Lifestyle Behaviors among Hypertensive Patients: An Integrative Literature Review.

Healthy lifestyle levels are low among adults with hypertension (HTN). Unfortunately, psychosocial factors contributing to patients' inability to meet healthy lifestyle recommendations are not well-understood. This integrative review examined the relationships of three psychosocial factors (self-efficacy, outcome expectancy, and social support) with dietary adherence (DA) and physical activity (PA) among adults with HTN. In total, 24 peer-reviewed studies were assessed. Results showed self-efficacy had small-to-large relationships with PA ( r = 0.02-0.46) and DA ( r = 0.06-0.79), with the strength of the associations varying by the assessed domain and country of origin. However, few studies reported a small relationship between the remaining factors (outcome expectancy and social support) and PA and DA. Thus, more efforts are needed to delineate the contributions of social support and outcome expectancies on DA or PA. When designing an intervention that focuses on improving PA or DA among adults with HTN, these psychosocial factors should be targeted.
