To assess compliance and knowledge of antihypertensive therapy amongst outpatients attending a hypertensive clinic

N = 262

Multistage sampling technique was used to select the eligible hypertensive patients from outpatients of a hypertension clinic

52.6

Cross-sectional

74.81/78.83

The significant reasons for MNA (p < 0.05): forgetfulness (OR = 14.8; 95% CI: 3.9 - 54.8); ran out of prescribed drugs (OR = 1.3; 95% CI: 0.1 - 0.4); avoiding side effects (OR = 3.0; 95% CI: 1.4 - 6.7) and absence of symptoms (OR = 3.3; 95% CI: 1.3 - 8.0). Factors significantly associated with adherence to antihypertensive treatment: religion (X2 = 5.0068, df = 1, p = 0.025) and knowledge (X2 = 6.6848; df = 1, p = 0.0097; F-exact test = 0.0184)

Purposive sampling from a rural primary health care

Qualitative

-

Facilitators of medication adherence included affordability of care (through health insurance), trust in orthodox “western” medicines, trust in doctor, dreaded dangers of hypertension, and use of prayer to support efficacy of pills. Inhibitors of medication adherence included inconvenient clinic operating hours, long waiting times, under-dispensing of prescriptions, side-effects of pills, faith motivated changes of medication regimen, herbal supplementation/ substitution of pills, and ignorance that regular use is needed. Local practices and norms were identified as important inhibitors to the uptake of healthier behaviours.
