Objective: Relationships exist between food addiction symptoms, weight bias internalization, and psychological distress, yet previous research is primarily cross‐sectional with adults from Western contexts. We examined the prospective relationships between food addiction symptoms, weight bias internalization, and psychological distress in Chinese adolescents. Methods: Over three time points (Time 1, baseline; Time 2, 6‐months; Time 3, 12‐months) spanning 1 year, we examined cross‐sectional and bi‐directional relationships between food addiction symptoms, weight bias internalization, and psychological distress in Chinese adolescents (N = 589; aged 14–18 years at baseline). Pearson correlations and cross‐lagged models examined the cross‐sectional and longitudinal relationships between food addiction symptoms, weight bias internalization, and psychological distress. Results: Cross‐sectional correlations suggested positive relationships between food addiction symptoms, weight bias internalization, and psychological distress at each time point. Regarding bi‐directional relationships, higher psychological distress was associated with both higher weight bias internalization and higher food addiction symptoms at the following time points. However, food addiction symptoms and weight bias internalization were not prospectively associated. Time 2 psychological distress did not significantly mediate the relationship between Time 1 weight bias internalization and Time 3 food addiction symptoms. Discussion: Findings suggest no direct longitudinal link between food addiction symptoms and weight bias internalization and vice versa. However, findings do suggest that psychological distress is temporally associated with higher food addiction symptoms and weight bias internalization in Chinese adolescents. Targeting psychological distress may prove useful in treatments of food addiction symptoms and weight bias internalization in Chinese adolescents. Public Significance: Positive associations exist between food addiction symptoms, weight bias internalization, and psychological distress, but findings are largely cross‐sectional and bound to adult populations from Western contexts. Using a longitudinal design in Chinese adolescents, findings suggested that baseline psychological distress was associated with higher food addiction symptoms and higher weight bias internalization at follow‐up time points. Treatments targeting psychological distress may be helpful in reducing food addiction symptoms and weight bias internalization in Chinese adolescents. [ABSTRACT FROM AUTHOR]

Objective: An extensive literature has documented the deleterious effects of weight bias internalization (WBI) on biopsychosocial health outcomes. Still, this research is largely confined to the Western context. Furthermore, few studies have explored associations between WBI and biopsychosocial health outcomes, including in non‐Western adolescent populations. Method: The present study explored the longitudinal relationships between WBI and body dissatisfaction, disordered eating, psychosocial impairment related to eating disorder features, and psychological and physical well‐being in a sample (N = 1549; aged 11–18 years at baseline) of Chinese adolescents. Relationships between study variables were examined between two waves of data measurement (Time 1, baseline, and Time 2, 6‐month). Cross‐lagged and multivariate models were used to explore prospective relationships between WBI and biopsychosocial correlates. Results: Bidirectional relationships were observed between WBI and biopsychosocial correlates in Chinese adolescents. Adjusting for covariates and other predictor variables, higher body dissatisfaction, disordered eating, psychosocial impairment, and psychological distress at Time 1 predicted higher WBI at Time 2. Furthermore, higher WBI at Time 1 predicted higher body dissatisfaction, disordered eating, psychosocial impairment, and psychological distress at Time 2. Discussion: Weight bias internalization and psychosocial correlates were interrelated across time in Chinese adolescents. Improving WBI might be promising in the prevention of eating and body image disturbances and diminished psychosocial well‐being. Similarly, reducing eating and body image disturbances and improving psychosocial well‐being might be useful prevention targets in reducing WBI in Chinese adolescents. Public Significance: The present study represents an initial effort to explore bidirectional relationships between WBI and biopsychosocial health outcomes in Chinese adolescents. Findings suggest bidirectional relationships between WBI and psychosocial variables, highlighting the potential utility of incorporating WBI interventions into eating pathology and poor psychosocial well‐being prevention designs for Chinese adolescents.

Objective: This study examined the bidirectional relationships between sleep quality, loss of control (LOC) eating, and night eating in Chinese adolescents using longitudinal data over an 18‐month study period. Method: Four‐waves of data measurement (Waves 1–4), at 6‐month intervals, were conducted with 2566 adolescents aged 11–17 years at baseline. A set of questionnaires were used to assess night eating, LOC eating, and sleep quality at each wave of data collection. Cross‐lagged models were applied to analyze the bidirectional relationships between night eating, LOC eating, and sleep quality. Results: Results indicated that higher night eating scores consistently predicted poorer sleep quality and higher LOC eating scores at Waves 1, 2, and 3. Furthermore, poorer sleep quality predicted higher night eating scores at Wave 1 and Wave 3, and higher LOC eating scores predicted higher night eating scores at Wave 1 and Wave 2. Discussion: These findings highlight that night eating, LOC eating, and sleep quality were interrelated across time in Chinese adolescents. Improving sleep quality and reducing LOC eating might be promising in the prevention of night eating in adolescents. Similarly, reducing night eating might be promising in improving sleep quality and reducing LOC eating in adolescents. Public Significance: This study explored the bidirectional relationship between night eating, LOC eating, and sleep quality in Chinese adolescents using cross‐lagged models. Findings indicate bidirectional relationships between these variables and highlight the potential utility in incorporating sleep, LOC eating, and night eating interventions in eating pathology prevention designs for adolescents.
