To assess the prevalence of

poor adherence and factors associated to anti-hypertensive treatment

N = 365

Systematic random sampling technique to select hypertensive patients from a specialized hospital

51.2

Cross-sectional

40.5

Factors hinder adherence: age group (46 - 55) (AOR = 0.30; 95% CI: 0.142 - 0.640), lack of medication information (AOR = 0.12; 95% CI: 0.258 - 0.583) and presence of co-morbidities (AOR = 0.50; 95% CI: 0.290 - 0.893). Muslim followers were 3 times more likely to be adherent to their treatment (AOR = 3.20; 95% CI:1.69 - 6.08)

To investigate antihypertensive medication non-adherence and its determinants among patients

N = 121

All eligible hypertensive patients from outpatients of two referral hospitals

62

Prospective cross-sectional

26.4

Factors significantly associated with MNA: family support (AOR = 0.170; 95% CI: 0.030 - 0.905); spot blood pressure (AOR = 0.052, 95% CI: 0.003 - 0.242), place of patient residence (AOR = 0.184; 5% CI: 0.024 - 0.597) and hypertension related complications (AOR = 21.73; 95% CI: 1.568 - 418.42)

Ethiopia

To assess the

adherence of the patients to anti-hypertensive medication and main risk factors contributing to MNA

N = 91

Purposive sampling was conducted among eligible hypertensive patients who attended a referral Hospital during the study period

56.06

Cross-sectional

68.13

Factors contributed to MNA significantly: economic problems (p = 0.04), less awareness about hypertension and its treatment (p < 0.01), social drug use (p < 0.01). Other factors were distance, forget fullness, insufficient information about the effect of MNA and adverse effect understanding
