BACKGROUND: Sleep problems are associated with problems of cognitive functioning, learning, attention and school performance. It has been found that sleep problems are highly prevalent in children with Autistic spectrum disorders (ASD), with rates ranging from 40% to 80%. We aimed to identify the prevalence of sleep problems on children with ASD in Indonesia and Japan. METHODS: A cross-sectional study was conducted in Surabaya, Indonesia and Kobe, Japan. Children aged 4-10 years old were enrolled using stratified cluster sampling. Children's Sleep Habits Questionnaire-Abbreviated (CSHQ-A) was used in this research to assess the sleep problems, consisted of 22 questions (NICHD SECCYD—Wisconsin). Data were analyzed with Mann-Whitney U test to compare the CSHQ-A scores between Indonesian and Japanese children, while the proportion of sleep problems was evaluated by chi-square test with 95% confidence interval. RESULTS: Fifty children with ASD were included in this study, 25 children from Kobe, Japan and 25 children from Surabaya, Indonesia. The prevalence of sleep problems on children with ASD was 60% (15 children) in Indonesia and 16% (4 children) in Japan respectively. There were significant differences in total waking during the night and in morning wake for the CSHQ-A between children from Indonesia and Japan (p<0.005). CONCLUSIONS: The prevalence of sleep problems on children with ASD was higher in children from Indonesia than from Japan.
