摘要

Weight status under-perception is protective against disordered eating behaviors and weight gain; however, it is unclear whether under-perception may confer protection across all weight classes. This work explored body mass index as a moderator of the association between weight status perception accuracy and disordered eating behaviors among adults with overweight or obesity. A total of 572 adults (58.7% female; age M = 39.50, SD = 11.57) with overweight or obesity (body mass index M = 31.50, SD = 6.24) completed a series of online questionnaires assessing uncontrolled, emotional, and restrained eating, eating disorder symptoms, weight status perception, and demographics. Controlling for race/ethnicity, age, and sex, linear and negative binomial regressions were used to test hypotheses. Compared to accurate weight status perception, under-perception was associated with less uncontrolled (p = .003) and restrained eating (p = .002). Under-perception was particularly protective against emotional eating (p = .022) and eating disorder symptoms (p = .017) for individuals of overweight or Class I obesity. In general, weight status under-perception was associated with fewer disordered eating behaviors. The protective effects of under-perception of weight status may be maximized for individuals of overweight or Class I obesity statuses.
