目的本研究的目的是研究超重/肥胖青年体重误解与饮食失调行为之间的横断面关联。方法在全国青少年到成人健康纵向研究第三阶段（2001-2002）的超重或肥胖青年（n= 5184）的子样本中，我们检验了体重感知不足（即认为自己体重健康或体重不足）与饮食失调（为控制体重而禁食/不吃饭、为控制体重而排便/服药、暴饮暴食/饮食失控）之间的横断面关联。以及使用性能增强产品/物质)。结果约20%的年轻成年女性低估了自己的体重，而男性的这一比例为48%。将自己的体重误认为健康的个体报告禁食/不吃饭（女性：OR: 0.25, 95% CI: 0.14-0.43；男性：OR: 0.31, 95% CI: 0.20-0.48）和呕吐或服用减肥药/泻药/利尿剂（女性：OR: 0.10, 95% CI: 0.04-0.25；男性：OR: 0.10, 95% CI: 0.04-0.25）以控制体重的可能性显著降低。在女性中，那些认为自己的体重状况是健康的人也不太可能报告暴饮暴食或饮食失控（or: 0.41, 95% CI: 0.24-0.71）。认为自己体重过轻的男性（OR: 2.06, 95% CI: 1.57-2.72）以及认为自己体重过轻的女性（OR: 2.29, 95% CI: 1.40-20.0）和男性（OR: 2.27, 95% CI: 1.13-4.55）更多地使用提高成绩的产品/物质。超重/肥胖的年轻人体重认知不足可能会带来一些与饮食行为失调有关的好处，但可能是使用性能增强产品/物质的风险因素。(c) 2016 Wiley期刊，Inc.（国际饮食失调杂志；49:937-946）
ObjectiveThe purpose of this study was to examine the cross-sectional association between weight misperception among young adults with overweight/obesity and disordered eating behaviors.MethodIn a subsample of young adults with overweight or obesity participating in Wave III (2001-2002) of The National Longitudinal Study of Adolescent to Adult Health (n=5,184), we examined the cross-sectional association between weight under-perception (i.e., perceiving oneself to be at a healthy body weight or underweight) and disordered eating (fasting/meal skipping for weight control, purging/pills for weight control, overeating/loss of control eating, and use of performance-enhancing products/substances).ResultsAbout 20% of young adult females under-perceived their weight compared to 48% of males. Individuals who misperceived their weight as healthy were significantly less likely to report fasting/meal skipping (Females: OR: 0.25, 95% CI: 0.14-0.43; Males: OR: 0.31, 95% CI: 0.20-0.48) and vomiting or taking diet pills/laxatives/diuretics (Females: OR: 0.10, 95% CI: 0.04-0.25; Males: OR: 0.10, 95% CI: 0.04-0.25) for weight control. Among females, those who misperceived their weight status as healthy were also less likely to report overeating or loss of control eating (OR: 0.41, 95% CI: 0.24-0.71). Greater use of performance-enhancing products/substances was seen among males who under-perceived their weight as healthy (OR: 2.06, 95% CI: 1.57-2.72) and among both females (OR: 2.29, 95% CI: 1.40-20.0) and males (OR: 2.27, 95% CI: 1.13-4.55) who perceived themselves to be underweight.DiscussionWeight under-perception among young adults with overweight/obesity may convey some benefit related to disordered eating behaviors, but could be a risk factor for the use of performance-enhancing products/substances.
