To determine the prevalence and predictors of adherence

to modern antihypertensive pharmacotherapy

N = 348

All the eligible hypertensive patients living in a selected urban slum

68

Cross-sectional

27/28.7

Factors significantly associated with adherence (p < 0.05): duration of hypertension for ≥ 5 years (AOR = 2.98; 95% CI: 1.73 - 5.14), hypertension was detected during checkups for conditions related to hypertension (AOR = 2.35; 95% CI: 1.25 - 4.39), living with ≤ 4 family members (AOR = 2.01; 95% CI: 1.52 - 3.50), family income of ≥ 3000 rupees (AOR = 2.56; 95% CI: 1.47 - 4.45), getting free drugs (AOR = 4.16: 95% CI: 1.36 - 12.69), perceived BP under control (AOR = 2.23: 95% CI: 1.17 - 4.26) and satisfied with current treatment (AOR = 3.77; 95% CI: 1.32 - 10.76)

To assess medication adherence in hypertensive patients and to identify the main barriers associated with medication adherence.

N = 608

Randomly selected hypertensive patients from the outpatient of internal medicine department of a teaching hospital

Belief barrier was reported in 39.14% patients. Access barrier and recall barrier were reported by 82.57% and 62.17%, respectively. 78.62% of patients reported that it is difficult to pay for the medication and 54.93% indicated that it is difficult to get a refill timely. Logistic regression analysis showed that the education level was not contributing to non-adherence (OR = 0.75, 95% CI: 0.64 - 0.87). However, duration of hypertension, (p = 0.031) showed a significant contributory effect to MNA (p = 0.031). Chi square analysis showed no relation between the adherence pattern and the number of antihypertensive medications being prescribed.
