论文· 神经性厌食症患者体重指数的对照分析 北京大学精神卫生研究所　(100083)　孔庆梅　张大荣 【摘　要】目的:探讨神经性厌食症患者体重指数(BMI)的特点及疾病的临床特征。方法:采用进食障 碍调查问卷(EDI-1)对30名神经性厌食症患者和30名正常对照者进行评定,计算EDI-1量表分、BMI。 结果:根据期望BMI和目前BMI的差值,厌食症患者可分为追求更瘦组和不追求更瘦组。不追求更瘦组的 目前BMI最低,追求更瘦组的目前BMI次之,正常对照组目前BMI最高,差异具有显著性(F=54·15,P 0·01);两病例组间期望BMI没有差异(P0·05),但都低于正常对照组。追求更瘦组EDI-1量表总分最 高、不追求更瘦组次之、对照组最低,差异具有显著性(P0·01)。结论:体重过低的厌食症患者可能希望 体重增加。但无论患者是否希望体重增加,期望体重指数都低于正常,实际上都是怕胖的。追求更瘦的患者 可能预后较差,这可能与患者较严重的认知偏差以及某些心理特征有关。 【关键词】　精神病学　神经性厌食症　病例对照研究　体重指数 Body Mass Index(BMI)of Anorexia Nervosa KONG Qingmei ZHANG Darong　Institute of Mental Health, Beijing University, 100083 【Abstract】Objective: To investigate BMI of patients with anorexia nervosa and find the relationship between BMI and clinical features·Methods: 30 femalewhometthe criteria of anorexia nervosa of ICD-10 and 30 normal controlswere eval- uated with the EDI-1·The current BMI, expected BMI, pre-morbid highest BMI were compared between patient group and control·Results: The current BMI and expected BMI of anorexia nervosa groupwere significantly lower than those of nor- mal controls (P0·01)·According to the difference between expected BMI and current BMI, anorexia nervosa group was divided intotwo subgroups: expecting lowerweight and not expecting lowerweight·The current BMI of the subgroup expecting lowerweight was just below normal limit, about 17·The current BMI of the subgroup not expecting lowerweight had already been far belownormal, about 15·The subgroup expecting lowerweight presented smaller age of onset and longer duration than the subgroup not expecting lowerweight (P0·05)·Conclusion: Patientswith very lowbodyweightmay be not so eager as those with relatively normal weight in seeking for more weight loss, but their expected BMI is still lower than normal· 【Key Words】　psychiatry　anorexia nervosa　case-control studies　body mass index 　　进食障碍,包括神经性厌食症和神经性贪食症, 曾被认为是西方文化的产物,然而随着经济的持续发 展,以及西方文化的进一步渗透,进食障碍在中国的 患病率明显增加[1,2]。1983年初至2001年底大约15 年期间北京大学精神卫生研究所共有51例进食障碍 病人住院资料,其中18例是在2000年10月以后的 1
