Negative familial weight talk and weight bias internalization in a US sample of children and adolescents

Background: Negative familial weight talk may contribute to higher weight bias internalization in pre- and early adolescents (hereafter referred to as children) and may differ by gender, weight status, and race and ethnicity. Objective: Examine the relationship between negative familial weight talk and weight bias internalization and examine differences by gender, weight status, and race and ethnicity. Methods: We cross-sectionally analysed 5th-7th graders (10-15 years old) living in Massachusetts (n = 375, 52.3% girls, 21.3% BMI >= 85th percentile, 54.8% non-Hispanic White). Negative familial weight talk frequency during the past 3 months was self-reported and discretized as 'never,' 'occasionally' (1-9 times) and 'often' (>9 times); the Modified Weight Bias Internalization Scale assessed weight bias internalization. Generalized linear models estimated the relationship between negative familial weight talk and weight bias internalization and sub-analyses estimated the relationship across gender, weight status, and race and ethnicity. Results are summarized as ratios of means (RoM). Results: Children experiencing negative familial weight talk occasionally (RoM = 1.12, p = 0.024) and often (RoM = 1.48, p < 0.001) had significantly higher weight bias internalization than children who never experienced it. In sub-analyses, experiencing negative familial weight talk often was associated with higher weight bias internalization among girls (RoM = 1.66, p < 0.001), boys (RoM = 1.32, p = 0.007), children with BMI <85th percentile (RoM = 1.44, p = 0.007) and BMI >= 85th percentile (RoM = 1.39, p = 0.001), and non-Hispanic White children (RoM = 1.78, p < 0.001), but not Hispanic (RoM = 1.25, p = 0.085) or non-Hispanic Black children (RoM = 1.20; p = 0.31). Conclusions: Frequent negative familial weight talk was associated with higher weight bias internalization across gender and weight status and in non-Hispanic White children only.
