长期氯氮平治疗的男性精神分裂症病人身体质量指数与精神病理症状的关系

目的探讨长期氯氮平治疗男性精神分裂症病人的身体质量指数（BMI）与精神病理症状的关系。方法对222例长期氯氮平治疗的慢性男性精神分裂症病人进行横断面调查,检测病人的身高和体重,并记录病人服药情况。同时用PANSS量表检测其精神病理症状。结果与正常人群的BMI分布相比,长期氯氮平治疗病人超重和肥胖的比例明显增加（P〈0.05）。以BMI进行分组,肥胖、超重、正常体重组和低体重组之间PANSS阴性症状量表（P〈0.001）、一般病理症状量表（P〈0.05）和总分（P〈0.001）之间均存在显著差异。与正常体重组和低体重组相比,肥胖组和超重组在PANSS阴性症状量表、一般病理症状量表和总分上均较低（P〈0.05,P〈0.01）。Pearson相关分析表明：BMI与PANSS总分（r=-0.248,df=222,P=0.000）PANSS阴性症状量表分（r=-0.256,df=222,P=0.000）和一般病理症状量表分均呈显著负相关（r=-0.19,df=222,P=0.004）,而与PANSS阳性症状无显著相关（P=0.23）。结论长期服用氯氮平的男性精神分裂症病人BMI明显增加;而且病人BMI越高,其临床症状、尤其是阴性症状和一般病理症状就越轻。
