Abstract
Background: Hypertension is one of the most important preventable causes of premature
mortality worldwide and it is one of the primary risk factors for heart disease and stroke. In
Ethiopia 10.6% and Addis Ababa, 30% of the population has been estimated to have
hypertension. Adherence to medication therapy and lifestyle change is an aspect of patients’
care that is often overlooked and should be evaluated as a crucial part of cardiovascular
management. Therefore, this study aimed to assess adherence and associated factors of
adherence to hypertensive management among hypertensive patients in Black Lion Hospital
chronic follow up unit.
Methods: A cross-sectional study was conducted. Systematic sampling technique was used to
select 286 study subjects. A structured standard questionnaire was used after some modifications.
Analysis was done using SPSS software. The descriptive analysis such as percentage, proportion,
frequency distribution and appropriate graphic presentation were used. Bivariate and multivariate
logistic regressions were employed. P-value <0.05 was considered statistically significant
association.
Results: Of 286 subjects included in the study, 165 (57.7%) were female and mean age was
52(22-83) years. The adherence level of respondents to medication, diet, substance and exercise
were 69.2%, 64.7%, 87.4% and 43.7% respectively. On regression analysis, married respondents
were two times more likely to adhere to anti-hypertensive medication compared to divorced
(AOR=2.00, 95%CI: 1.330-6.744, P=0.008). Very well informed respondents were 2
times(COR=1.94,95%CI:1.042-3.622,P=0.037), 4 times(AOR=4.17,95%CI:1.862-.340,P=0.001)
and 7 times(AOR=6.47,95% CI:2.514-16.664,P<0.001) were more likely to adhere to
medication, diet and recommended substance management than their counterparts respectively.
Respondents with the duration of diagnosis of five or more years were 89 %( AOR=0.11, 95%
CI: 0.013-0.955, P=0.045) and 90 %( AOR=0.10, 95% CI: 0.026-0.340, P<0.001) were less
likely to adhere to medication and substance recommendation than their counterparts.
Conclusion and recommendation: The rates of adherence to medicine and life-style changes
were generally found to be low in these study participants. The cause of non-adherence is
different according to the type of adherence. Each recommendation should be assessed
individually in terms of adherence.
