青少年受虐待经历与进食障碍症状的关系

Association between childhood abuse and eating disorder symptoms in a sample of adolescents

目的:对湖南省青少年的受虐待经历与进食障碍症状的流行情况进行调查,并探索两者间的关系。方法:本研究为横断面研究设计。使用研究用儿童受虐筛查表(SQCA)对被试被父亲、母亲和其他家人虐待的情况进行评估,采用进食态度调查表(EAT-26)对有进食障碍症状(11≤EAT-26得分<20)和可能患进食障碍(EAT-26得分≥20)的被试进行筛查。共有3743名中学生的调查资料纳入数据分析。结果:本研究中学生报告自己被父亲、母亲和其他家人虐待的发生率分别为17. 7%、15. 6%和2. 8%,报告自己有进食障碍症状和可能患进食障碍的发生率分别为22. 0%和7. 1%。女生中,进食障碍症状越严重的分组中,被试报告自己被父亲、母亲和其他家人虐待的发生率也越高(χ2> 15. 21,均P <0. 001),控制人口学因素以后,被母亲(OR=1. 76,95%CI=1. 31～2. 34)和其他家人(OR=1. 68,95%CI=1. 00～2. 81)虐待对其进食障碍症状的严重程度增加具有风险预测作用。男生中,不同进食障碍症状等级组之间三种来源儿童期虐待的筛查率均无显著差异(χ2<6. 29,均P> 0. 05)。结论:湖南省青少年被虐待和进食障碍症状的自我报告发生率均较高;女生的被虐待经历与其进食障碍症状密切关联,男生中两变量的关联性并不明显。
