<![CDATA[Background: Overweight among adolescents has increased significantly in Indonesia, with a prevalence of 12.1% among those aged 13-15 years. Padangsari Community Health Center recorded an overweight rate of 20.5%. Risk factors for overweight include high stress levels, sedentary activity duration, and excessive carbohydrate intake, which may contribute to fat accumulation and increase the risk of non-communicable diseases such as type 2 diabetes, cardiovascular diseases, and hypertension. Objective: To analyze the relationship between stress levels, sedentary activity duration, and carbohydrate intake and the occurrence of overweight among junior high school students in Semarang. Methods: This study employs an observational analytic case-control design with matching. The sample was selected using simple random sampling, consisting of 40 cases and 40 controls. Dietary intake data were collected using the SQ-FFQ questionnaire, sedentary activity duration was assessed using the ASAQ, and stress levels were measured using the DASS-42. Bivariate analysis was conducted using McNemar's test and Odds Ratio analysis. Results: Junior high school students with high stress levels were 3.2 times more likely to experience overweight (OR: 3.20; p: 0.027). Those with long sedentary activity duration had a 4.67 times higher risk of being overweight (OR: 4.67; p: 0.013). Excessive carbohydrate intake was associated with a 3.75 times risk of being overweight (OR: 3.75; p: 0.197). Conclusion: Stress, sedentary activity duration, and high carbohydrate intake are risk factors for overweight among junior high school students in Semarang City.
