Evaluating Autism Risk Factors and Their Impact on Children in Thi-Qar, Iraq

Background Autism is a neurodevelopmental disorder marked by difficulties in social communication, language, restricted interests, and repetitive behaviors. Aim This study aims to identify potential risk factors for autism among children and assess their effects on early developmental skills. Methods A case-control study was conducted from September 2022 to September 2023, involving 298 children with autism (265 boys, 33 girls) aged four to 12 from the Thi-Qar Autistic Children Center and private clinics in Iraq. A control group of 300 children (150 boys, 150 girls) was also included. Data were collected through a specialized questionnaire covering demographics, neonatal history (e.g., jaundice, birth asphyxia), parental age, and developmental skills (motor milestones, speech, handwriting). Results Among the 298 children with autism enrolled, 265 (89%) were boys and 33 (11%) were girls. Children with autism had a positive family history of autism in 207 (69%) compared to 15 (5%) in the control group (p < 0.001). Paternal age over 35 years at the time of birth was noted in 159 (53%) versus 75 (25%) for the control group (p < 0.001). Maternal age over 35 showed no significant difference (p = 0.23). Hypoxia at birth was present in 153 (51%) children with autism compared to 45 (15%) in the control group (p = 0.001). Significant developmental delays were observed, including speech defects in 210 (70%) children with autism versus 15 (5%) in controls (p < 0.001). In terms of handwriting, 240 (80%) children with autism demonstrated acceptable handwriting skills, while 60 (20%) did not, compared to 264 (88%) in the control group who achieved handwriting skills, resulting in a p-value of 0.23. Conclusions The findings indicate that boys are more affected than girls, with significant risk factors including family history, paternal age, and neonatal birth asphyxia. Children with autism demonstrated marked delays in motor skills and speech defects, emphasizing the need for early detection and intervention.
