<![CDATA[Adolescent obesity has become one of the most pressing global public health issues, with a consistently increasing prevalence across countries. This study aimed to explore factors associated with obesity among adolescents. This study employed an analytical observational design with a cross-sectional approach. A total of 468 obese high school adolescents were selected using total sampling. The variables included dietary patterns, physical activity, sedentary behavior, and sleep duration. Dietary patterns were assessed using the Global School-based Student Health Survey (GSHS-WHO). Physical activity was measured using the Physical Activity Questionnaire for Adolescents (PAQ-A). Sedentary behavior was assessed using the Sedentary Behaviour Questionnaire (SBQ), and sleep duration was measured using the Adolescent Sleep Habits Survey (ASHS). Obesity was determined using body mass index (BMI). The sample consisted of all obese high school adolescents in Tomohon City (n=468). Data were analyzed using chi-square tests and logistic regression. Results: The findings showed that 69,7% of respondents were classified as class I obesity. Dietary patterns, physical activity, sedentary behavior, and sleep duration were all significantly associated with adolescent obesity (p<0.05). Dietary patterns (OR=2,897; p=0,002) and physical activity (OR=2,843; p=0,004) were significant contributors to obesity among adolescents. Conclusion: Adolescent obesity is influenced by dietary patterns, physical activity, sedentary behavior, and sleep duration. Dietary patterns and physical activity were the dominant factors contributing to adolescent obesity and should therefore become the primary focus of obesity prevention efforts.]]>
