摘要

Weight suppression (WS), the difference in one's highest and current adult weight excluding pregnancy, is associated with eating disorder (ED) symptom onset and maintenance. There is increasing evidence that WS is related to ED symptoms in non-clinical samples, but there are no known studies examining the interaction of WS and current body mass index (BMI) in this group. History of overweight is common in those with EDs, and higher weight status often delays identification and treatment. This study examined the interaction of WS and current BMI on body dissatisfaction and eating pathology in undergraduate men and women. Undergraduates (N = 476) completed online surveys assessing current height and weight, weight history, and eating attitudes and behaviors. In women (n = 333), both BMI and WS were positively associated with body dissatisfaction, restraint, and global ED symptoms. In men (n = 143), there were no significant associations with BMI, but WS was related to greater body dissatisfaction, restraint, global ED symptoms, and loss-of-control eating. Moderation analyses revealed that the effect of current BMI on shape concern (p =. 005), weight concern (p =. 002), global ED symptoms (p =. 01), and purging behaviors (p =. 04) in women and restraint (p =. 03) in men weakened at the highest levels of WS. Results suggest that WS is salient in a non-clinical sample and underscore the need to evaluate both weight history and the presence of disordered eating in individuals across the BMI spectrum.
