The physical status of children with autism in China.

The height, weight and BMI of children with autism was investigated and analyzed to find the physical status of children with autism in China. Three hundred and eighty boys and 49 girls diagnosed with autistic disorder participated. Their parents were interviewed with a questionnaire about general information, and children were evaluated with Childhood Autism Rating Scale, and height and weight were measured. Children with autism had high level height, weight and BMI; the rate of height >or=P(75) was less in 6-11 years old group than that in 2-5 years old group in boys and all children. The prevalence of at-risk-for or being overweight was 31.8% and 17.0% in 2-5 years old group, were 37.9% and 21.8% in 6-11 years old group. At-risk-for-overweight/overweight of children with autism had no relationship with their core symptoms, the older age was the only predictor for lower height and at-risk-for-overweight. Prevalence of at-risk-for-overweight and overweight in children with autism was high. Children's height level decreased, and being at-risk-for-overweight increased with age.
