Factors associated with eating disorders among Indonesian adolescents at boarding schools

Objectives: Eating disorders (EDs) are a significant global issue among adolescents, including those in boarding schools; however, this population remains under-researched. This study investigated the factors associated with EDs among Indonesian boarding school students. Methods: Using a cross-sectional approach, 1,400 adolescents were selected through purposive sampling. The study examined factors such as body mass index (BMI), body image, mood, loneliness, and weight loss using a modified combination of questionnaires. Data analysis was performed using logistic regression in SPSS 21 with a significance level of 0.05. Results: Four factors significantly influenced the risk of developing ED. A lower BMI (underweight or normal) decreased the risk (OR=0.2 and 0.3, respectively; CI: 0.140-0.360 and 0.231-0.524, respectively). A lower drive for leanness reduced the likelihood of EDs (OR=0.49; CI: 0.347-0.713). Lower levels of muscularity-oriented eating also decreased ED risk (OR=0.39; CI: 0.273-0.573). Conversely, unhealthy weight loss experiences significantly increased ED risk (OR=8.9; CI: 6.728-11.827). Conclusions: These findings highlight the complex factors contributing to EDs risk, emphasizing the need for targeted interventions to address body image concerns, nutritional practices, and weight loss experiences to promote the well-being of students in boarding schools. The implementation of structured health education programs that emphasize balanced nutrition, positive body image, and healthy weight management is recommended to address eating disorders. Nursing and health professionals play key roles in the development and delivery of these programs.
