45. Elzubier et al. 2000 [52] | Sudan | 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 | 76.3 | Cross sectional | 40.4 | Using multiple logistic regression analysis only variable that is positively and significantly associated with MNA is being unable to buy drugs (p < 0.001) |
46. Joho et al. 2012 [32] | Tanzania | 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 | 56.3 | Cross sectional | 44/35.44 | 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) |
