Abstract


Diabetes mellitus has become a major public health concern, with Indonesia ranking fifth globally in prevalence, affecting approximately 19.5 million people. This study aimed to evaluate the relationship between knowledge and medication adherence among patients with type 2 diabetes mellitus receiving oral antidiabetic therapy at the Prambanan Community Health Center. A quantitative cross-sectional design was employed involving 50 respondents who met the inclusion criteria. Data were collected using two validated instruments: the Diabetes Knowledge Questionnaire-24 (DKQ-24) and the Morisky Medication Adherence Scale-8 (MMAS-8). The results showed that 56% of respondents had a good level of knowledge and 52% demonstrated high adherence to oral antidiabetic therapy. Statistical analysis using Spearman’s rho revealed a significant positive correlation between knowledge and medication adherence (p = 0.003; r = 0.357). These findings indicate that higher patient knowledge contributes to better adherence behavior. Strengthening diabetes education and pharmacist counseling is recommended to enhance treatment adherence and optimize glycemic control in primary healthcare settings.
