To assess medication adherence and factors associated with it among hypertensive patients

N = 286

Systematic random technique was used to selected eligible hypertensive patient from a specialised hospital

57.7

Cross-sectional

30.8/59.1

Respondents less likely to adhere to medication who had: private business (AOR = 0.28, 95% CI: 0.130 - 0.606; p = 0.001) and duration of diagnosis of five or more years (AOR = 0.11; 95% CI: 0.01 - 0.95; p = 0.045). Respondents more likely to adhere to anti-hypertensive medication: who were married (AOR = 2.00; 95% CI: 1.33 - 6.74), attended most of the time private clinic to receive health care (AOR = 6.34; 95% CI: 1.17 - 33.96), treatment duration two to four years (AOR = 3.81; 95% CI: 1.26 - 11.51) and who were motivated (AOR = 2.84; 95% CI: 1.47 - 5.43)

To assess adherence to antihypertensive therapy and associated factors among hypertensive patients on follow up

N = 384

Systematic random sampling technique to select patients from an university teaching hospital

63

Cross-sectional

35.4/33.5

Variables, significantly associated with treatment adherence: female sex (AOR = 0.48; 95% CI: 0.28 - 0.82), knowledgeable about hypertension and its treatment (AOR = 6.21; 95% CI: 3.22 - 11.97), decreased distance from the hospital (AOR = 2.02; 95% CI: 1.19 - 3.43), having no or one co morbidity (AOR = 2.5; 95% CI: 1.01 - 6.21) and who have controlled hypertension (AOR = 2.93; 95% CI: 1.73 - 4.96)

Ghana and Nigeria

To determine factors associated with

MNA among hypertensive patients

N = 357

All eligible patients were recruited from four hospitals from Ghana and Nigeria

57.5

Cross sectional

66.7/65.4

Adherence showed association with concern about medications (r = −0.0347, p = 0.002) and knowledge of hypertension (r = 0.14, p = 0.006). MNA was related with: depression (r = −0.208, p < 0.001), formal education (p = 0.001), younger age (p = 0.000), use of herbal preparation (p = 0.014), insured participants (p = 0.032) and poor BP control (p = 0.006).
