Abstract

Background: Improving health literacy has been found to play a significant role in enhancing medication adherence in patients with type 2 diabetes.

Purpose: The present study aims to evaluate health literacy and its association with medication adherence among diabetic patients in Jordan.

Patients and methods: This cross-sectional study included 400 diabetic patients, predominantly female (68.8%), with a median age of 58 years, attending the endocrinology outpatient clinic at Albasheer Hospital in Amman, Jordan, between August and December 2023. Patients were recruited using convenience sampling, including those aged 18 and older, literate, diagnosed with T2DM for at least one year, and on at least one medication for T2DM. Sample size was calculated based on the Events Per Variable (EPV) criterion to ensure sufficient power for logistic regression analysis. Data were collected using two validated instruments: the Jordanian Diabetic Health Literacy Questionnaire (JDHLQ), assessing health literacy, and the Medication Adherence Report Scale (MARS-5), measuring medication adherence. A binary logistic regression model was constructed to identify variables associated with adherence levels.

Results: The study enrolled 400 diabetic patients (females =68.8%). While most of the participants (70.3%) reported high adherence levels, results revealed a window for health literacy improvement as the median for the JDHLQ score was 22 (ranging from 18 to 25) out of a maximum possible score of 32. More than half of the participants replied "never" to "I forget to take my medications", followed by "I stop taking my medications for a while".

Conclusion: The binary regression model revealed that a higher JDHLQ score significantly increased the odds of a high adherence level. The significant association between improved health literacy and medication adherence necessitates the implementation of educational campaigns for enhancing literacy and hence medication adherence among patients with type 2 diabetes.

Keywords: Jordanian; MARS-5; adherence; diabetes mellitus; health literacy.
