目的 探讨住院精神分裂症患者腹部B超检查结果的异常情况及其相关因素.方法 采用自编的调查量表对我院住院的499例精神分裂症患者进行腹部B超检查和一般情况调查,并对腹部B超检查的阳性结果及其临床相关因素进行分析.结果 腹部B超检查阳性194例（38.9％）,其中肝胆异常176例（35.3％）,占总阳性率的90.7％,脂肪肝111例（22.2％）,占总阳性率的57.2％,肝胆结石57例（11.4％）,占总阳性率的29.4％.腹部B超阳性结果的患者中精神分裂症Ⅰ型、年龄大、高体重、服药时间和住院时间长的比例高于腹部B超结果阴性的患者（P＜0.05）.相关分析显示：腹部B超的阳性率与精神分裂症Ⅰ型、年龄、体重、服药时间和住院时间呈正相关（r=0.111,0.121,0.274,0.099,0.134;P＜ 0.05）.进一步Logistic回归分析显示：年龄每增加1岁,腹部B超阳性的发生率增加3.6％（OR：1.036; 95％CI：1.014-1.058;P=0.001）;体重每增加1 kg,腹部B超阳性的发生率增加6.0％（OR：1.060,95％CI：1.040-1.080;P＜0.001）.结论 年老、肥胖是住院精神分裂症患者腹部B超阳性率高的相关危险因素,值得临床重视.

英文摘要：

Objective To probe into the abnormal situation and related factors about the abdominal B ultrasound of hospitalized schizophrenia patients.Methods Using the self-made survey scale to make a general investigation and a research on abdominal B ultrasound of 499 cases of schizophrenia patients in our hospital,and analyze the positive results of abdominal ultrasound examination and its related clinical factors.Results In the abdominal ultrasound examination,194 cases were positive （38.9%）.Among them,176 cases belonged to liver abnormalities （35.3%）,accounting for 90.7% of the total positive rate,111 cases were those who had fatty liver（22.2%）,accounting for 57.2% of the total positive rate,57 cases were the calculi of liver and gallbladder （11.4%）,accounting for 29.4% of the total positive rate.The positive results about the abdominal B ultrasound of patients showed that the ratio was higher than the negative result in schizophrenia Ⅰ type,old age,high bodyweight,the time of taking drug and the length of hospital stay （P〈0.05）.Correlation analysis also showed that the positive rate of abdominal ultrasound with schizophrenia Ⅰ type,age,weight,the time of taking drug and length of hospital stay were positively correlated （r=0.111,0.121,0.274,0.099,0.134; P〈0.05）.Further Logistic regression analysis showed that age,every increase 1 year,the incidence of abdominal B exceeded to a positive 3.6% increase （OR=1.036; 95% CI：1.014 1.058; P=-0.001） ; every increase 1 kg weight,abdominal B exceeded to a 6.0% increase in the incidence of positive （OR=1.060; 95% CI：1.040 1.080;P〈0.001）.Conclusion For hospitalized schizophrenia patients,old age and obesity are the related risk factors for high positive rate of abdominal B.Such conclusion should be worthy to call clinical attention.
