To estimate adherence with drug use, associated factors, and the effect of adherence on BP control

N = 198

Registered eligible hypertensive patient attended medicine department of a teaching hospital


Cross sectional


Using multiple logistic regression analysis only variable that is positively and significantly associated with MNA is being unable to buy drugs (p < 0.001)

To investigate factors affecting treatment adherence with antihypertensive therapy among hypertensive patients with the guide of the HBM conceptual framework

N = 135

Randomly selected patient from three hypertensive clinics


Cross sectional


With the use of bivariate analysis treatment compliance showed significant positive association with perceived benefit (r = 0.27; p = 0.001) cues to action(r = 0.19; p = 0.022). Treatment adhrence showed significant negative association with: perceived barrier to treatment (r = −0.53; p = 0.000)

Measurement of BP control achievement, estimating prevalence of drug adherence behaviour and establishing the association between drug adherence behaviour and achievement of BP control

N = 102

Convenience sampling from outpatients of a tertiary hospital




Participants with normal BP measurements were more than three times as likely to report maximal adherence to prescribed drug schedule (AOR = 3.37: 95% CI: 1.38 - 8.24)
