Constant vigilance: The impact of weight stigma, vigilance, and internalization on maladaptive eating behaviors.

Abstract

Weight stigma (social devaluation because of weight) and weight bias internalization (self-stigma due to weight) have been independently implicated in maladaptive eating, which ultimately contributes to poor cardiometabolic health. Additionally, vigilance (being on the lookout for social devaluation) is connected to stress, poor sleep, and depression. Most research considers these factors separately but establishing how these variables interact with one another is essential to understanding their cumulative impact on health behaviors. Using a diverse national panel of adults in the United States (N = 1,051), this study tested several statistical moderated mediations in which weight stigma was both directly associated with maladaptive eating and indirectly associated with maladaptive eating via vigilance. We simultaneously examined whether the relationship between weight stigma and vigilance was moderated by self-stigma. Results indicated that experiencing weight stigma was directly related to each of the maladaptive eating behaviors (eating to cope, restrictive dieting frequency, and binge eating). Weight stigma was also indirectly related to each eating behavior through vigilance; this indirect relationship was stronger among those with high levels of weight bias internalization, compared to those with low levels of weight bias internalization. Race moderated the relationship between weight stigma and vigilance, such that participants identifying as Black had a stronger relationship between them. These results provide support for a theoretical model which explains how weight stigma, self-stigma, and vigilance interact with one another to produce negative health behaviors and highlight the importance of further investigation of vigilance in the context of weight stigma.
