Exploring the prospective relationships between food addiction symptoms, weight bias internalization, and psychological distress in Chinese adolescents

Abstract

ObjectiveRelationships 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.MethodsOver 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.ResultsCross‐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.DiscussionFindings 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 SignificancePositive 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.
