Abstract
BACKGROUND: Poor adherence in treatment and medication is a global issue in curing the chronic
diseases such as hypertension. The present study was conducted to identify the factors related with
medication adherence among hypertensive patients referred to the health centers of Borujerd based
on the Pender’s Health Promotion Model (HPM).
MATERIALS AND METHODS: This cross‑sectional study was conducted on 463 patients who were
referred to the comprehensive health centers of Borujerd city by cluster sampling method in 2019.
The data were collected using a questionnaire including demographic variables and Pender’s HPM
constructs. Data were analyzed by SPSS 18 software using Pearson correlation coefficient and
linear regression.
RESULTS: The mean and standard deviation of the participants’ age was 63.29 ± 11.2 years. The
results showed that hypertensive patients had a relatively desirable level of medication adherence
behavior. Perceived barriers (β = −0.169), perceived self‑efficacy (β = 0.196), activity related affect
(β = 0.232), and following medication regimen (β = 0.225) were the best predictors of performing
the medication adherence behavior. In total, different structures of the HPM explained 42.2% of the
variation of medication adherence behavior changes.
CONCLUSIONS: According to the findings, the design of educational programs using HPM is
recommended to increase the medication adherence among hypertensive patients.
