Weight stigma and mental health outcomes in early-adolescents. The mediating role of internalized weight bias and body esteem.

Background: Weight stigma is increasingly common in early adolescence and may lead to weight bias internalization, with negative consequences for mental health outcomes. This study aimed to: examine the relations of perceived weight stigma and internalized weight bias with early adolescents' internalizing symptoms and disordered eating behavior; explore the mediating role of internalized weight bias on the relations of perceived weight stigma with internalizing symptoms and disordered eating behaviors; examine body esteem as a mediator between internalized weight bias and mental health outcomes.

Methods: A sample of 406 early adolescents (59.6% girls) aged between 11 and 13 participated in this cross-sectional study. They completed self-report measures assessing perceived weight stigma, internalized weight bias, body esteem, internalizing symptoms and disordered eating.

Results: Path analysis indicated that perceived weight stigma was positively related with internalizing symptoms and internalized weight bias. Further, internalized weight bias was negatively related with body esteem and positively related with internalizing symptoms and disordered eating. Internalized weight bias mediated the relations of perceived weight stigma with internalizing symptoms, disordered eating and body esteem. Further, body esteem mediated the relations of internalized weight bias with internalizing symptoms and disordered eating behavior.

Conclusions: The findings highlight internalized weight bias as a psychological mechanism potentially explaining negative links of weight stigma with internalizing symptoms and disordered eating in early adolescence. The results emphasize the need for early intervention during this developmental stage, in order to prevent psychological and behavioral outcomes of weight stigma and internalized weight bias.
