Disordered eating is one of the serious nutritional issues and becoming more entrenched among adolescents in non-Western countries. Early adolescence, in particular, is a beginning point for the onset of disordered eating. Hence, it should be addressed during early stage of adolescence to prevent further adverse health outcomes. The study aimed to determine the biological (gender, ethnicity, BMI-for-age, and pubertal development), psychological (body image perception, self-esteem, and depressive symptoms), and socio-environmental (socioeconomic status and sociocultural influences) factors contributing to disordered eating among early adolescents. A cross-sectional study was canied out among 322 students (39.4% males, 60.6% females) aged 10 and I1 years (mean age = 10.86 ± 0.58 years) from five randomly selected primary schools in Selangor. Data on biopsychosocial factors were collected using a set of selfadministered questionnaire; while disordered eating was examined using Children's Eating Attitude Test (ChEAT). Body weight and height of subjects were measured and their body weight status was determined according to BMI-for-age (z-scores). About two-fifths of the subjects (40.1%) were reported to have disordered eating. The associations between disordered eating with gender, BMI-for-age (z-scores), pubertal development, body weight perception, depressive symptoms, and socioeconomic status were not significant. However, disordered eating was found to be positively correlated with body size dissatisfaction (r=0.129, p<0.05), parental influence(r=0.337, p<0.01), peer influence (r=0.355, p=<0.01), and media influence (r=0.228, p<0.01). Negative correlations were reported between disordered eating with body parts satisfaction (r=- 0.173, p<0.01) and self-esteem (r=-0.143, p<0.05). The mean ChEAT scores were significantly different among three ethnic groups (χ²K-W=39.385, p<0.01), whereby Chinese subjects had the lowest mean ChEAT score (12.77 ± 9.43), followed by Indians (21.75 ± 12.17) and Malays (21.26 ± 15.48). Multiple linear regression analyses indicated that parental influence, ethnicity, and body parts satisfaction explained 18.8% of the variances in the disordered eating model. In conclusion, disordered eating was prevalent among early adolescents in Selangor. Therefore, preventive and intervention programmes should integrate biopsychosocial components such as correcting parental influence in terms of encouragement, teasing, and modeling, explaining cultural differences between ethnic groups, and promoting positive body image to prevent disordered eating among early adolescents.
