Demographic correlates of children and adolescents with Autistic disorder

Comparison of the demographic characteristics of patients provides useful information to their identification. This study aimed to determine the demographic characteristics of children and adolescents with autistic disorder (AD).
In this cross-sectional case-control study, 115 children and adolescents with AD were selected from Autism Society Rehabilitation Center in Tabriz, Iran, and 112 normal children and adolescents from the public schools, in 2014. The participants in both groups were matched regarding age and gender. Diagnosis of AD was performed using diagnostic and statistical manual of mental disorders-4th edition (DSM-IV) criteria and clinical diagnostic interviews by two child and adolescent psychiatrists. The demographic information of children and adolescents and their parents were collected from the medical records of children and interviews with their mothers.
Most of the children with autism had second or higher birth order and had families with more than three members. Mothers of children with autism had significantly lower levels of education and were mostly housewives. Fathers of autistic children mostly had high school diploma and fewer had university education, and most of them were employed. However, there was no statistically significant difference between the AD group and the control group regarding the average height and weight of children and the residence (urban or rural) and age of parents at childbirth.
The demographic characteristics of the two groups of children and adolescents with AD and normal controls were different from each other regarding family size, birth order, parent occupation, and parent education variables.
