Abstract
INTRODUCTION: Hypertension (HPT) is recognized as a significant public health problem worldwide from a health and economic perspective. This study determined predictors of nonadherence to HPT medications in Ghana using the health belief model. METHODS: A cross-sectional descriptive survey employing a quantitative approach was conducted among HPT patients who routinely attend clinics at selected hospitals in the Brong Ahafo region of Ghana. Respondents (n = 399) were recruited using a multistage sampling technique. RESULTS: The prevalence of nonadherence was 63.7% (n = 254). Nonadherence to hypertension medication was associated with lower education status (p=0.009). In logistic regression analysis, patients with high "perceived susceptibility" and "perceived severity" were more likely to forfeit their HPT medication schedules, while patients with high "perceived barriers" and "cues to action" were less likely to skip their medication. CONCLUSION: The present study suggests a plausible path to improving medication adherence in this population. Given the high prevalence of nonadherence, policymakers need to urgently design tailor-made health promotion interventions to ensure optimal health outcomes.
