Background: Type 2 Diabetes Mellitus (DM type 2) is a chronic disease in adults due to the body's resistance to insulin. Purpose: This study aims to analyze the determinants of the incidence of type 2 DM. Methods: The study design was a case-control. The case population in this study were patients with type 2 DM who had been diagnosed by doctors based on data available in the medical record of Bintang Bayu Health Center. In contrast, the control population was patients who did not suffer from type 2 DM. The study's sample size was 138 people, with a ratio of cases to controls of 1:2. The case group consisted of 46 people, and the control group comprised 92 people. The sampling technique used nonprobability sampling, namely consecutive sampling. Data collection was carried out directly by distributing questionnaires. Analysis of the research data began by calculating the frequency distribution of each variable, which was analyzed using the Chi-square test and logistic regression. Results: Diet (p = <0.001; OR = 4.7; 2.231 – 10.154), knowledge (p = 0.033; OR = 2.3; 1.129 – 4.785), physical activity p = 0.010; OR = 2.8; 1.342 – 6.032), hypertension (p = <0.001; OR = 4.9; 2.089 – 11.784) were significant to the incidence of type 2 DM. The most dominant variable was hypertension p = <0.001; OR = 7.3 (2.581-20.680). Conclusions: Poor diet, poor knowledge, light physical activity, and hypertension were significant factors in the incidence of type 2 DM.
