Background: Although 2/3 of US adults and nearly 1/3 of US children have overweight or obesity, weight stigma is common. Many with overweight or obesity ascribe negative ideas to themselves, resulting in internalized weight bias (IWB). In adults, IWB has been associated with psychosocial problems; however, this relationship has been studied little in children. This study aims to describe IWB in children with overweight and obesity and to study the association of children's IWB with experienced weight bias, self-esteem, and their parents' IWB. Methods: Children ages 9-18 with overweight or obesity completed the Weight Bias Internalization Scale (WBIS), Rosenberg Self-Esteem Scale, and Perception of Teasing Scale; parents completed the Weight Bias Internalization Scale-Modified and the Perceived Weight Discrimination Scale. Descriptive statistics were used to assess IWB, self-esteem, and experienced weight stigma. Chi-square and t-tests were used to examine associations between categorical and continuous variables, respectively. Multivariate linear regression was used to identify correlates of IWB in children. Results: Of 111 child participants, the median WBIS score was 2.8 out of 7. Higher IWB was associated with more peer teasing (p < 0.001) and lower self-esteem (p < 0.001). IWB in children was not associated with child BMI z-score (p = 0.590) or higher parent IWB (p = 0.287). Conclusions: Children with overweight and obesity who have experienced more teasing by peers or who have lower self-esteem are more likely to have a higher IWB. However, increasing child BMI z-score and parent IWB are not associated with higher child IWB.
