In a total population survey of childhood psychosis in the region of Göteborg, 20 children (2 in every 10,000) fulfilled the diagnostic criteria for infantile autism formulated by Rutter. There was a male preponderance with 15 boys and 5 girls. Eighty-five percent of the mothers were older than average. Mean maternal age in the autistic sample was 30.7 years, compared with 26.0 years in the general population. The difference is statistically significant at the .1% level. There was a strong tendency toward increasing risk of autism in the child with increasing maternal age. The fathers too were much older than average.
在哥德堡地区进行的一项儿童精神病总体调查中，20名儿童（每10000名中有2名）符合鲁特制定的婴儿自闭症诊断标准。男性占多数，有15名男孩和5名女孩。85%的母亲年龄高于平均水平。自闭症样本中母亲的平均年龄为30.7岁，而普通人群中母亲的平均年龄为26.0岁。这种差异在0.1%的水平上具有统计学意义。随着母亲年龄的增加，孩子患自闭症的风险有强烈的上升趋势。父亲的年龄也比平均水平大得多。
