<![CDATA[Diabetes mellitus (DM) is a non-communicable disease whose prevalence continues to increase, including among adolescents, in relation to unhealthy dietary patterns and low physical activity. This study aimed to identify factors associated with DM incidence as reflected by random blood glucose (RBG) status among adolescents in the working area of Cengkareng Sub-district Community Health Center. A quantitative analytic-correlational study with a cross-sectional approach was conducted among 80 adolescents aged 10–19 years selected using purposive sampling. Data were collected using questionnaires on sugary food and beverage consumption, physical activity, and family history of DM, together with random blood glucose measurements. Data were analyzed using univariate and bivariate analyses with the Pearson Chi-Square test at α = 0.05. Most respondents had high sugary food and beverage consumption (70.0%), low or inactive physical activity (47.5%), no family history of DM (62.5%), and normal RBG status (73.8%). The bivariate analysis reported significant associations between sugary food and beverage consumption (χ² = 5.685; p = 0.017), physical activity (χ² = 9.399; p = 0.009), and family history of DM (χ² = 28.242; p = 0.001) with RBG status. The findings indicate that physical activity and family history were particularly important factors associated with RBG status, while healthy dietary habits remain relevant for long-term prevention. Early screening and health education are recommended, especially for adolescents with a family history of DM.]]>
