ObjectivesThis study was aimed to determine the factors associated with antihypertensive adherence based on the Health Belief Model (HBM).MethodsA cross-sectional study was conducted in a rural area of China in 2014. The questionnaire included information about demographics, a scale based on the HBM, and the four-item Morisky Medication Adherence Scale.Results745 hypertensive patients participated in the study (345 men, 400 women). Patients’ mean age was 56.4 ± 10.8 years. The prevalence of adherence was 43.5%. Structural equation modeling showed that men, older participants, and those with greater knowledge of hypertension showed better medication adherence than did other participants. Based on the HBM, higher levels of self-efficacy and perceived severity and a lower level of perceived barriers were associated with better antihypertensive adherence. Self-efficacy was one of the most important mediating variables affecting antihypertensive adherence.ConclusionsAntihypertensive adherence was not optimal among patients in Beijing. Given that many factors are associated with medication adherence, individualized intervention strategies should be carried out in Beijing, China, especially in community settings.Practice implicationsMedication adherence can be improved by enhancing patients’ self-efficacy because it was the most important influence and mediating variable.
