Comparative study of the relationship between pregnancy and childbirth factors and autism in healthy children and children with autism

BACKGROUND: Autism is a group of developmental disorders of the nervous system, the main manifestations of which are defects in social interactions and communication, as well as repetitive behaviors and limited interests. The etiology of autism is not limited to a single factor. Therefore, the aim of this study was to compare the relationship between pregnancy and childbirth factors and autism in healthy children and children with autism. MATERIALS AND METHODS: The present study was a cross-sectional study that was performed on 200 children in Isfahan in 2021. The instrument in this study was a researcher-made questionnaire. The collected data were analyzed using the Statistical Package for the Social Sciences (SPSS) version 22 software. RESULTS: The results of data analysis between the two groups with Mann–Whitney U test showed that there was a significant relationship between maternal age at delivery, father's age at delivery, gestational age at delivery, interval between pregnancies, and the length of hospital stay (P ≤ 0.05). Also, the results of data analysis with Chi-squared test showed that there is a significant relationship between the two groups in terms of economic status, place of residence, multiple pregnancies, neonatal sex, and disease in infancy (P ≤ 0.05). CONCLUSION: The results of this study showed that economic status, place of residence, multiple pregnancies, sex of the baby, and disease in infancy can be effective factors for this disease. According to the results of the study, by considering the factors related to autism, many cases can be adjusted and corrected as much as possible before attempting to conceive.
