Abstract

The prevalence of hypertension in African Americans is the highest of any population in the United States, and this population also demonstrates lower rates of adherence to mediation. Social support and patient-provider communication have been considered as reinforcing factors to help hypertensive patients achieve optimal blood pressure control. The purpose of this study was to examine the association of social support and patient-provider communication and medication adherence for hypertensive African American men and women. The study was guided by the theory of reasoned action. This study was conducted to determine whether social support and patient-provider communication was associated with medication adherence by self-report, age, and gender. A quantitative cross-sectional design with secondary data analyses was used. The sample included 566 hypertensive African American men and women between the ages of 21and 65 years who participated in a survey administered in the Counseling African Americans to Control Hypertension clinical trial collected between 2004 and 2011. The independent variables were social support and patient-provider communication; the dependent variable was medication adherence. Descriptive, 2-way analysis of variance and hierarchical logistic regression model analyses indicated a significant association between patient-provider communication and medication adherence. There was no significant difference in the relationship between social support, patient-provider communication, and age and gender and medication adherence. The implications of this study for social change include improvement in policies and development programs to support the critical role of providers in ensuring medication adherence in hypertensive African American patients.
