Introduction: Limited research been done on disparities in disordered eating for immigrant adolescents in Taiwan, so this study aims to investigate factors associated with disordered eating for this vulnerable population. This study tests a dual pathway to disordered eating through bodyweight misperception and negative weight-based social interactions (including family and friend weight-teasing) for immigrant and non-immigrant adolescents in Taiwan. Methods: This is a cross-sectional study analyzing data collected from March to June 2019. Seven hundred twenty-nine adolescents aged between 13 to 16 years from 37 classes in three junior high schools in New Taipei City were included in the final analysis. Standardized assessment tools were used in the questionnaire to measure disordered eating (EAT-26) and depressive mood (BSRS-5). Stata was used for statistical analysis, and SEM modeling was used to conduct path analysis to investigate disordered eating pathways for immigrant and non-immigrant adolescents. Results: Immigrant adolescents had a significantly higher disordered eating prevalence and higher mean EAT-26 score than non-immigrant adolescents (p<0.05). The full model supported the hypothesis that a dual pathway model of negative weight-based social interactions and bodyweight misperception leads to disordered eating through depressive mood. Individual factors, including bodyweight misperception, depressive mood, and unhealthy eating behavior, were significantly associated with disordered eating for immigrant adolescents. Social factors, including friend and family weight-teasing and mother’s higher education, were significantly associated with disordered eating for non-immigrant adolescents. The bodyweight misperception pathway to disordered eating and individual factors had a more significant effect on immigrant adolescents. In contrast, the adverse weight-based social interactions pathway to disordered eating and social factors had a more significant impact on non-immigrant adolescents. Discussion: This study provides evidence that pathways for disordered eating may differ for immigrant and non-immigrant adolescents in Taiwan. Public health practitioners should focus on addressing bodyweight misperception among immigrant adolescents and negative weight-based social interactions among non-immigrant adolescents in disordered eating prevention efforts. Further research is warranted to understand factors influencing the different pathways to disordered eating for immigrant and non-immigrant adolescents.
