本研究考察了患有青少年饮食失调症的年轻女性相对于没有饮食失调症的女性的身体形象和体重的变化。方法对神经性厌食症（AN, n= 10）、神经性贪食症（BN, n= 27）、暴食症（BED, n= 42） 3个诊断组和3个对照组（noED, n= 659）的体重指数（BMI）、自我报告的当前体型、理想体型和体重不满进行比较。在一个调整了种族和BMI的模型中，研究了发病前2年和1年、发病年和发病后1年和2年的因变量。结果AN组除发病前2年外，其他时间点bmi均较低。与未接受教育的女孩相比，接受教育的女孩的身体质量指数与目前的自我评价和体重不满意度之间的关系明显更强。BMI在BN组和noED组之间没有差异。在所有时间点上，患有BN的女孩都报告了更大的当前体型和更大的体重不满。随着时间的推移，BED组的BMI高于noED组。与noED女孩相比，BED女孩报告了更高的当前体型评级和体重不满。患有AN、BN或BED的女孩与患有noED的女孩在身体理想评分上没有差异。体重似乎对患有AN的女孩比没有ed的女孩对体型的影响更大。没有证据表明随着时间的推移，BN会加速体重增加。与noED组相比，BED组的体重可能随着时间的推移而增加，但需要更大规模的研究。在这三组人中，理想的体型似乎与诊断状态无关。相反，患饮食失调症的风险似乎来自对体型的高估和对体重的不满意。©2004 by Wiley Periodicals, Inc。中国医学杂志（英文版），2004。
BackgroundThis study examined the changes in body image and weight in young women with an adolescent eating disorder, relative to women without an eating disorder (noED).MethodThree diagnostic groups, anorexia nervosa (AN;n= 10), bulimia nervosa (BN;n= 27), and binge eating disorder (BED;n= 42) and three comparison groups (noED;n= 659 each) were compared on body mass index (BMI) and self‐reported current body size, ideal body size, and weight dissatisfaction. Dependent variables were examined 2 and 1 year before the onset, the onset year, and 1 and 2 years after the onset of the eating disorder in a model that was adjusted for ethnicity and BMI.ResultsBMI was lower in the AN group at all time points except 2 years before onset. AN girls evidenced a significantly stronger relation between BMI and current self‐ratings and weight dissatisfaction than noED girls. BMI did not differ between the BN group and the noED group. Girls with BN reported larger current body sizes and greater weight dissatisfaction across all time points. The BED group had higher BMI than the noED group across time. BED girls reported greater current body size ratings and weight dissatisfaction than the noED girls. Girls with AN, BN, or BED did not differ from the noED girls on body ideal ratings.DiscussionBody weight seems to influence perception of body size more so for girls with AN than for noED girls. No support was found for an accelerated weight gain over time for BN. Weight may increase over time for the BED group relative to the noED group, but larger studies are needed. Across all three groups, ideal body size appears to be unrelated to diagnostic status. Rather, the risk for developing an eating disorder appears to arise from size overestimation and related weight dissatisfaction. © 2004 by Wiley Periodicals, Inc. Int J Eat Disord 36: 315–327, 2004.
