Abstract

Aims: The study aimed to assess diabetes health literacy, adherence to diabetes medication, and its associated factors in Kerala, India, the most advanced Indian state in epidemiological transition with the highest literacy level in India.

Materials and methods: We conducted a community-based cross-sectional study among 280 diabetes patients (mean age 62 years, male 42%) selected by multistage cluster sampling. Information on sociodemographic variables was collected using a pretested structured interview schedule. Diabetes health literacy was assessed using the revised Michigan Diabetes Knowledge test. Adherence to diabetes medication was assessed using the Hill-Bone subscale. Binary logistic regression analysis was done to find out the factors associated with diabetes health literacy and medication adherence.

Results: Good diabetes health literacy was reported by 35.7% [95% confidence interval (CI): 30.1-41.6] of the patients. Perfect adherence to diabetes medication was reported by 33.2% of patients (CI: 27.7-39.1). Patients who reported regular newspaper reading [adjusted odds ratio (AOR) 3.16; CI: 1.57-6.30], using the internet (AOR 2.23; CI: 1.11-4.50) and insulin use (AOR 2.60; CI: 1.35-5.00) were more likely to report good diabetes health literacy compared to their counterparts. Patients who reported reading health magazines (AOR 2.75; CI: 1.01-7.60) were more likely to report perfect medication adherence compared to those who did not.

Conclusion: Why diabetes health literacy and medication adherence were low among diabetes patients in the most literate state needs further investigation. Interventions to enhance diabetes health literacy and medication adherence may be undertaken among diabetes patients encouraging them to read newspapers and health magazines regularly and use the internet.

Keywords: Diabetes health literacy; Diabetes patients; India; Kerala; Medication adherence.
