Abstract
BACKGROUND: The aim of this study was to investigate pre-, peri-, and postnatal factors, screen time in a group of patients with autism spectrum disorder (ASD) and age and sex-matched clinical controls to evaluate risk factors specific to ASD. METHODS: The study included 211 ASD patients (177 boys, 34 girls; mean age 44.3 ± 13.0 months) and 241 (190 boys, 51 girls; mean age 44.6 ± 14.1 months) age and sex group matched clinical controls. Non-ASD diagnoses were expressive language disorder (n = 135, 56.0%), intellectual disability (n = 15, 6.2%), attention deficit-hyperactivity disorder (n = 6, 2.4%), oppositional disorder (n = 6, 2.4%), and other behavioral or emotional problems (no diagnosis; n = 79, 32.8%). A sociodemographic data form was used to collect data regarding pre-, peri-, and postnatal factors and total daily screen exposure. RESULTS: According to our findings, maternal severe psychological stress and depression during pregnancy, and maternal postpartum depression were more frequent in the ASD group (p = 0.005, p = 0.035, and p = 0.001 respectively). There was a statistically significant difference between groups with regards to maternal any medication use during pregnancy (p = 0.004). The mean duration of daily screen exposure was higher in the ASD group (9.90 ± 5.10 h) compared to non-ASD children (4.46 ± 3.40 h; p < 0.001). A ROC curve showed that 8.5 h and above total daily screen exposure (AUC = 0.808 [95% CI: 0.769-0.848], p < 0.001; 55% sensitivity, 90.5% specificity) is likely to be associated with increased risk for ASD. CONCLUSION: Our study suggests that prenatal maternal psychological stress, prenatal and postpartum depression, and excess exposure to screen might be related to an increased risk for ASD.
