Parental communication about body weight can influence children’s emotional well-being and eating behaviors. However, little is known about the role of parental self-stigma concerning weight and social position variables (ie, race/ethnicity, income, and gender) in weight communication. This study examined how parents’ self-stigmatization for their own weight (ie, weight bias internalization) and self-stigmatization for their child’s weight (ie, affiliate stigma) relates to weight talk frequency with their children, and whether these associations vary across parental race/ethnicity, income, and gender. Parents (n = 408) completed a cross-sectional, online survey about their weight communication and self-stigmatization. Linear regression was used to examine the relationships among these variables, including interactions between the stigma variables and social position variables in predicting weight talk. Higher levels of weight bias internalization and affiliate stigma were strongly associated with increased parental weight talk frequency; parents who endorsed higher levels of internalized bias about their own weight expressed greater affiliate stigma for their child’s weight, regardless of demographic characteristics or weight status. Associations between the stigma variables and weight talk outcomes were stronger among fathers and parents of higher income. Findings highlight the importance of considering weight stigma variables in parental weight communication research.
