目的:探讨不同首发年龄精神分裂症患者的临床特征,以及社会人口学影响因素.方法:根据美国精神障碍诊断与统计手册第5版的精神分裂症诊断标准,选取15~70岁患者2 016例,由精神科医生采用简明国际神经精神访谈、精神症状维度评定量表(CRDPSS)和阳性与阴性症状量表(PANSS)进行诊断和评估.以18岁和25岁作为精神分裂症早发、中发及晚发的分组界值.采用方差分析、多重相关分析和多重线性回归的方法进行统计分析.结果:早发型患者的PANSS量表总分(73.8±28.0)和CRDPSS量表总分(11.7±5.4)均为最高.女性、受教育程度高、汉族、首发年龄较早、起病形式较慢等特征与PANSS量表和CRDPSS量表总分及其各维度分数正关联(标化回归系数:0.04~0.47),收入水平和吸烟与PANSS量表和CRDPSS量表总分及其各维度分数负关联(标化回归系数:-0.04~-0.14).结论:早发型精神分裂症患者的症状严重程度更高,女性、受教育水平高、早发病、慢性起病是精神分裂症患者症状严重的危险因素.
Objective:To explore the clinical characteristics and related socio-demographic factors of schizo-phrenia patients with different ages of onset.Methods:Totally 2 016 patients with schizophrenia aged 15 to 70 were selected according to the diagnostic criteria for schizophrenia in the Diagnostic and Statistical Manual of Mental Disorders,Fifth Edition.All of the patients were interviewed by psychiatrists using the Mini International Neuropsy-chiatric Interview to diagnose schizophrenia,Clinical-Rated Dimensions of Psychosis Symptom Severity(CRDPSS)and the Positive and Negative Syndrome Scale(PANSS)to assess symptoms.The cut-off points were 18 and 25 years old for three age groups,i.e.early onset(EOS),youth onset(YOS)and adult onset(AOS).Statistical analy-ses were performed by analysis of variance Pearson correlation analysis,and multivariate linear regression.Results:The early-onset patients had the highest total PANSS score(73.8±28.0)and CRDPSS score(11.7±5.4).Fe-male gender,high education level,Han ethnicity,early onset age,and slower onset of illness were negatively corre-lated with the total and dimension score of PANSS scale and CRDPSS scale(standardized regression coefficient:0.04-0.47),and income level and smoking were negatively correlated with those score(standardized regression coefficient:-0.04--0.14).Conclusion:Early-onset schizophrenia patients have more severe symptoms,and fe-male,high education level,early-onset disease,and chronic onset are the risk factors of symptom severity in patients with schizophrenia.
