Abstract

Addressing disparities in blood pressure control must include supporting antihypertensive medication adherence (MA). Developing effective MA interventions requires identifying the most important factors influencing MA. In this review, the authors aimed to meta-analyze the results of research testing associations between factors potentially influencing antihypertensive MA and assessed antihypertensive MA in historically underrepresented populations. Additional exploratory analyses focused on system-level factors, which have been understudied and may particularly impact disparities in MA. A health sciences librarian assisted with searching across 10 databases. Inclusion criteria included (1) published in English, (2) sample of adults with hypertension, (3) ≥50% of participants having self-identified as a race/ethnicity underrepresented in the country where the study was conducted, and (4) reporting sufficient data to calculate effect size(s). Fifty-eight studies were eligible for inclusion. Nine factors met criteria for planned analyses. Older age (r = 0.08, P < .01; k = 26 studies) and higher income (r = 0.11, P = .01; k = 15) were significantly correlated with better MA. Having depressive symptoms was significantly correlated with worse MA (r = -0.18, P < .01; k = 11). Effect sizes for sex, education level, marital status, number of medications, comorbidities, and perceived social support were not significant. System-level factors examined included insurance coverage, access to healthcare, perceived barriers, having a primary care provider, perceptions of their healthcare provider, and experiences of discrimination in healthcare. Understanding the impact of factors associated with antihypertensive MA in historically underrepresented adults can support development of targeted, culturally relevant MA interventions. Future research should examine the impact of system-level factors on antihypertensive MA among historically underrepresented populations.
