该研究的目的是发现瑞典7至15岁学龄儿童中抽动障碍和抽动秽语综合征（TS）的流行病学分布。共有4479名儿童及其父母被要求填写一份涵盖运动和声音联系的调查问卷。采用了三阶段程序：筛选、访谈和临床调查。297名儿童（190名男性，107名女性）被发现有联系。根据DSM-IV标准，TS在总人口中的0.6%中被发现，另外0.8%有慢性运动联系，0.5%有慢性发声抽搐。此外，4.8%的儿童有短暂的联系。总共有6.6%的7至15岁儿童目前患有或在过去一年中经历过某种抽动障碍。不同的抽动障碍的患病率在年幼的儿童和男性中较高，并且与学校功能障碍高度相关。TS的患病率比以前认为的要高，但其他抽动障碍在这一儿童人群中更常见。
The aim of the study was to find the epidemiological distribution of tic disorders and Tourette syndrome (TS) in Swedish school children aged 7 to 15 years. A total population of 4479 children and their parents were asked to fill in a questionnaire covering both motor and vocal ties. A three-stage procedure was used: screening, interview, and clinical investigation. Two hundred and ninety-seven children (190 males, 107 females) were found to have ties. TS, according to DSM-IV criteria, was found in 0.6% of the total population, another 0.8% had chronic motor ties, and 0.5% had chronic vocal tics. Further, 4.8% of the children had transient ties. All together 6.6% of 7- to 15-year-old children currently had or had experienced some kind tic disorder during the last year. Prevalence of different tic disorders was higher among younger children and in males, and was highly associated with school dysfunction. The prevalence of TS was higher than was previously thought but other tic disorders were more common in this childhood population.
