Negative emotional eating patterns in Chinese adolescents: A replication and longitudinal extension with latent profile and transition analyses.

This study, which is a longitudinal extension of previous cross-sectional studies in Chinese and American college students and general adults (Dixit, He, Whited, Ellis, & Zickgraf, 2023; He, Chen, Wu, Niu, & Fan, 2020; Xu et al., 2024), used latent profile and latent transition analyses to investigate negative emotional eating patterns and the stability of these patterns in 1462 Chinese adolescents (41% boys, aged 11-17 years) at baseline and 18 months later. We also explored baseline demographic predictors of negative emotional eating patterns and the associations between these patterns and outcome variables measured 18 months later. Negative emotional eating was measured with the Adult Eating Behavior Questionnaire (emotional undereating and emotional overeating subscales). Latent profile analysis (LPA) replicated the four patterns of negative emotional eating in each wave of assessment: low emotional eating (Low-EE), emotional overeating (EOE), emotional undereating (EUE), and emotional over- and under-eating (EOE-EUE). Latent transition analysis (LTA) showed that the EE patterns had transition probabilities of <55% remaining in the same class across 18 months. Furthermore, relative to adolescents in the stable Low-EE group, adolescents in all other stable or unstable emotional eating groups in LTA were linked to higher eating disorder psychopathology and psychological distress measured 18 months later. Thus, emotional eating, regardless of type (i.e., EOE, EUE, and EOE-EUE) and stability (i.e., stable or unstable), may be a viable research and treatment target in improving adolescents' eating behaviors and mental health.
