Obesity is a major global public health problem, with its prevalence continuing to increase worldwide. This study aimed to analyze the associations of family history, junk food consumption, and sugar-sweetened beverage consumption with obesity among students of the Faculty of Health Sciences, UIN Syarif Hidayatullah Jakarta. This cross-sectional study was conducted in June 2025 and involved 201 students selected using probability proportional to size sampling. Primary data were collected using a self-administered questionnaire. Sugar-sweetened beverage consumption was assessed using the Beverage Intake Questionnaire (BEVQ-15) over the previous month, while junk food consumption was assessed using a Food Frequency Questionnaire (FFQ). Data were analyzed to determine the associations between the studied factors and obesity. The results showed no significant associations between junk food consumption or sugar-sweetened beverage consumption and obesity (p>0.05). However, a family history of obesity was significantly associated with obesity (p=0.018; OR=3.348; 95% CI=1.297–8.644). In conclusion, family history was significantly associated with obesity, whereas junk food and sugar-sweetened beverage consumption were not. Students with a family history of obesity are encouraged to maintain a healthy diet, engage in regular physical activity, and monitor their body weight regularly to reduce their risk of obesity. Future studies should include additional determinants, such as total energy intake, sleep quality, and physical activity, to provide a more comprehensive understanding of obesity.
