Key result
Positive attitude linked to ~2.2-fold higher antihypertensive medication adherence in elderly patients.
Why the study?
Hypertension in older adults requires adherence to pharmacological therapy to prevent complications, motivating an analysis of how knowledge level and attitude relate to medication adherence in elderly hypertensive patients.
Are knowledge level and attitude associated with medication adherence in elderly patients with hypertension?
Cross-Sectional (n=313)
No
Are knowledge level and attitude associated with medication adherence in elderly patients with hypertension?
Both knowledge level and positive attitudes are significantly associated with antihypertensive medication adherence in elderly patients, with attitude showing the strongest association.
May inform adherence counseling in elderly hypertension patients; leaves open whether interventions improve outcomes in prospective trials.
Hypertension is a chronic disease commonly experienced by older adults and requires adherence to pharmacological therapy to prevent complications. This study aimed to analyze the association between knowledge level, attitude, and medication adherence among elderly patients with hypertension at RSUD H. Abdul Aziz Marabahan. This analytical observational study employed a cross-sectional design involving 313 respondents selected using purposive sampling. Data were collected using knowledge and attitude questionnaires and the Medication Adherence Report Scale (MARS-10). Data were analyzed using the Chi-square test and logistic regression. The results showed that 217 respondents (69.4%) had good knowledge, 190 (60.7%) demonstrated positive attitudes, and 174 (55.6%) were adherent to their medication regimen. Bivariate analysis revealed significant associations between knowledge and medication adherence (p < 0.001) and between attitude and medication adherence (p < 0.001). Multivariate analysis confirmed significant associations between knowledge (p < 0.001; Exp(B) = 1.838) and attitude (p = 0.001; Exp(B) = 2.176) with medication adherence. Attitude had a higher Exp(B) value than knowledge. In conclusion, knowledge and attitude were significantly associated with antihypertensive medication adherence among elderly patients, with attitude demonstrating the strongest association. These findings highlight the importance of health education and fostering positive attitudes to improve medication adherence among older adults with hypertension

Aziza et al. (2026) conducted a cross-sectional in Hypertension (n=313). Knowledge level and attitude vs. Poor knowledge or negative attitude was evaluated on Medication adherence assessed by the Medication Adherence Report Scale (MARS-10) (OR 2.176, p=0.001). Knowledge (Exp(B)=1.838, p<0.001) and attitude (Exp(B)=2.176, p=0.001) were significantly associated with antihypertensive medication adherence in elderly patients.
