This work was a follow-up study (birth years 1999-2003) of the prevalence of autism in children of Somali background living in the county of Stockholm, Sweden. In a previous study (birth years 1988-98), the prevalence of autism associated with learning disability* was found to be three to four times higher among Somali children compared with other ethnicities in Stockholm. We examined all records of children of Somali background, born from 1999 to 2003, registered at the centre for schoolchildren with autism and learning disability. The census day was 31 December 2009. The prevalence of autism and PDDNOS (with learning disability) was 0.98% (18/1836) in the Somali group and 0.21% (232/111555) in the group of children of non-Somali origin (p<0.001). The increased prevalence remained and was now between four and five times higher in children of Somali background. A clinical observation was that more than 80%, in addition to autism and learning disability, had a profound hyperactivity. The findings accord with many other studies reporting higher prevalence rates of autism in children of immigrant mothers. We discuss the need for further research of underlying mechanisms.
本研究是对生活在瑞典斯德哥尔摩县的索马里背景儿童自闭症流行率的后续研究（出生年份为 1999-2003 年）。在之前的一项研究（出生年份为 1988-98 年）中，与其他族裔相比，斯德哥尔摩的索马里儿童的自闭症相关学习障碍的流行率高出三到四倍。我们检查了所有在自闭症和学习障碍儿童中心注册的、出生于 1999 年至 2003 年的索马里背景儿童的记录。普查日为 2009 年 12 月 31 日。在索马里群体中，自闭症和 PDDNOS（伴学习障碍）的流行率为 0.98%（18/1836），而非索马里裔儿童群体的流行率为 0.21%（232/111555）（p<0.001）。现在，这种增加的流行率在索马里背景的儿童中仍然高出四到五倍。临床观察发现，除了自闭症和学习障碍外，超过 80%的儿童还存在严重的多动症状。这些发现与许多其他研究报告一致，即移民母亲的儿童自闭症发病率更高。我们讨论了进一步研究潜在机制的必要性。
