A consecutive series of 214 patients (125 males, 89 females) who met the Research Diagnostic Criteria for schizophrenia were studied to determine gender differences in age at onset of the illness and sociodemographic attributes. The immediate family's first awareness of psychotic symptoms or signs and age at first presentation in hospital were used as indices of onset; male patients had a significantly earlier age of onset than females. By the time they were 30 years of age, 83% of male patients had already become ill and only 66% of females had done so. Significantly more females than males were married at the time of first contact with hospital. Married males did not differ from married females in age at onset of illness, suggesting that patients who marry may have late onset.
对符合精神分裂症研究诊断标准的连续214例患者（125例男性，89例女性）进行了研究，以确定该疾病发病年龄和社会人口学特征方面的性别差异。将直系亲属首次意识到精神病症状或体征以及首次住院就诊年龄作为发病指标；男性患者的发病年龄显著早于女性。到30岁时，83%的男性患者已经发病，而只有66%的女性患者发病。首次与医院接触时已婚的女性显著多于男性。已婚男性与已婚女性在发病年龄上没有差异，这表明结婚的患者可能发病较晚。
