Overnutrition among adolescents is a growing public health problem that poses a risk for noncommunicable diseases in adulthood. This condition is influenced by various factors, including consumption of sugar-sweetened beverages, physical activity, and socioeconomic conditions such as pocket money. Purpose: This study aims to analyze the relationship between consumption of sugar-sweetened beverages, physical activity, and pocket money on the prevalence of overweight status among adolescents in Purwakarta Regency. Method: The study employed an analytical observational design with a cross-sectional approach. The sample consisted of 79 adolescent respondents aged 13–15 years, selected using purposive sampling. Data on sugar-sweetened beverage consumption were collected using the Food Frequency Questionnaire (FFQ), physical activity was measured using the Physical Activity Questionnaire for Children (PAQ-C), pocket money was obtained through structured interviews, while nutritional status was determined based on age-adjusted body mass index (BMI-for-age). Data analysis was performed using univariate and bivariate methods, including Spearman’s rho test, with a significance level of 0.05. Result: The results showed that more than a quarter of the respondents were overweight (34.2%). Most respondents had moderate consumption of sugar-sweetened beverages (68.4%), moderate physical activity (60.8%), and low pocket money (67.1%). The bivariate analysis results showed a significant association between physical activity and overweight status (p-value ≤ 0.05). Additionally, pocket money also showed a significant association with overweight status (p-value ≤ 0.05). Conclusion: These findings indicate that behavioral and economic factors play a role in shaping respondents’ consumption patterns and nutritional status. Therefore, efforts to prevent overweight status among adolescents should be implemented through nutrition education, increased physical activity, and monitoring of sugar-sweetened beverage consumption, while taking into account the economic conditions of adolescents.
