Daily weight stigma experiences, and disordered and intuitive eating behaviors among young adults with body dissatisfaction.

Objective: The present study aimed to extend naturalistic weight stigma research by examining the following aims among young adults with body dissatisfaction and varied body mass indices (BMIs): (1) characterize the frequency of individuals' daily weight stigma experiences, and contextual variations, over a 14-day period; (2) examine whether BMI moderated daily associations between weight stigma experiences relative to eating disorder symptoms and intuitive eating behaviors.

Method: Women (n = 174) and men (n = 24) completed a 14-day daily diary protocol. Concurrent and time-lagged multilevel models examined associations between daily weight stigma, and eating disorder and intuitive eating behaviors among women only due to the small subsample of men.

Results: Over the 14-day assessment, 43.94% (n = 87) of participants experienced weight stigma. Weight stigma rates varied based on how, where, and by whom weight stigma was expressed, and via BMI. Further, among women, multiple concurrent within-person associations were identified between women's daily weight stigma experiences and daily eating disorder symptoms (skipping meals, binge eating, and body dissatisfaction). Time-lagged associations also showed that women's weight stigma experiences on a given day were associated with a greater likelihood that they would limit the amount of food they consumed the next day. These associations did not differ via women's BMIs.

Discussion: Collectively, these findings provide important information on how weight stigma experiences unfold in daily life among individuals with body dissatisfaction and varied BMIs, and the proximal and more enduring impact of women's daily weight stigma experiences on their use of multiple adverse eating behaviors that can promote poor health.

Public Significance: The present findings provide important information on how, where, and by whom weight stigma experiences unfold in daily life among young adults with body dissatisfaction and varied body weights, as well as the proximal and more enduring impact of women's daily weight stigma experiences on their use of a variety of adverse eating behaviors that can promote poor health.
