The prevalence of overweight and obese in boys were significantly higher than those in girls (30.6% vs. 13.0%; χ ² = 40.55, P<0.01). Compared with normal weight group and low weight group, the scores of drive for thinness (DT), body dissatisfaction (BD), low self-esteem (LSE) and eating disorder risk composite (EDRC) were significantly higher in overweight and obese group ( P<0.05). There was a positive association between the scores of DT ( r = 0.19), BD ( r = 0.30), LSE ( r = 0.09), interceptive deficits (ID) ( r = 0.08) and EDRC ( r _s = 0.11) with body mass index (BMI) ( P< 0.05).

【摘要】 目的 了解蚌埠市超重肥胖青少年进食障碍相关症状和心理行为特征, 为预防青少年肥胖和进食障碍的发 生提供科学依据。 方法 采用分层整群抽样的方法, 抽取蚌埠市小学四年级至初中三年级共 910 名学生, 并进行问卷调査 和体格测量, 分析超重肥胖与进食障碍的相关性。 结果 共发现超重肥胖学生 203 名, 占 22.3%; 正常体重学生 547 名, 占 60.1%; 低体重学生 160 名, 占 17.6%。男生超重肥胖率 (30.6%, 147名)髙于女生 (13.0%, 56名), 差异有统计学意义 (χ ² = 40.55, P<0.01)。超重肥胖组青少年瘦身倾向、不满体型、低自尊感和饮食障碍危险评分得分均髙于体重正常组和低体重 组 ( F 值分别为7.83, 29.37, 3.99, 17.03, P值均<0.05); 且瘦身倾向、不满体型、低自尊感和内感受缺陷得分与体质量指数均 呈正相关 ( r 值分别为 0.19, 0.30, 0.09, 0.08, P值均<0.05)。随着体质量指数的增加, 青少年进食障碍的总体危险性增髙 ( r _s = 0.11, P<0.01)。 结论 青少年肥胖所导致的一系列身心问题, 增加个体患进食障碍的风险。应积极预防肥胖的发生, 矫 正和干预青少年进食障碍。
