Abstract
Methodology: A descriptive cross-sectional study was conducted among the 224 hypertensive
patients attended to the Medical clinic, Teaching Hospital Jaffna during November 2022. A
pretested interviewer-administered questionnaire was used to collect data about socio-
demographic factors and medication adherence whilst Data extraction sheet was used for
identifying treatment related factors. Medication adherence was assessed with the help of
Morisky Medication Adherence Scale-8 (MMAS-8) and scores were categorized as good and
poor adherence. Then association was found with selected factors by using Chi square test.
Results: Two hundred and twenty four participants were interviewed with the response rate of
100%. Majority of the participants (n=145, 64.7%) were male. The mean age of the participants
was 64.5 years with (SD=9.6). Good adherence level was noted as 46.4% (n=104) and poor
adherence level was 53.6%. The mean score of Medication adherence was 5.9 out of 8.
Medication adherence had significant association with marital status (p=0.026), frequency of
alcohol drinking (p=0.020), state of the hypertensive condition (p=0.018) and number of clinic
visit at last three months (p=0.037).
Conclusion: The study indicated that less than half of the participants had good level of
adherence to antihypertensive medications. Forgetfulness is the predominant reason for poor
adherence. Identified factors which affected adherence levels were marital status, frequency of
alcohol drinking, state of the hypertensive condition and number of clinic visit at last three
months.
