Insights
Prenatal and obstetric factors like cesarean birth, prematurity, and benzodiazepine use are linked to developmental disabilities. Cumulative risks, not single factors, increase the likelihood of these conditions in children.
Area of Science:
- Obstetrics
- Pediatrics
- Developmental Psychology
Background:
- Identifying prenatal and obstetric risk factors is crucial for understanding and mitigating developmental disabilities.
- Previous research has explored various factors, but a comprehensive analysis linking specific obstetric events to distinct developmental outcomes is needed.
Purpose of the Study:
- To investigate the association between prenatal and obstetric risk factors and the development of disabilities in children.
- To determine if specific risk factors, such as medication use, delivery mode, and gestational duration, correlate with particular types of developmental disabilities.
Main Methods:
- Retrieved data on medication use (benzodiazepines), gestational weeks, delivery mode, duration, and fetal presentation from medical records and interviews.
- Clinically assessed the developmental status of 107 children using standardized methods.
- Employed Fisher exact test with post hoc analysis of standardized residuals to identify statistically significant correlations.
Main Results:
- Cesarean section, prematurity, and maternal benzodiazepine use were significantly associated with multiple disabilities.
- Autism spectrum disorders showed a higher incidence with post-term delivery and induced labor.
- Developmental coordination disorder was more frequently observed in post-term births.
- No significant correlation was found between delivery duration or fetal presentation and developmental disabilities.
Conclusions:
- Developmental disabilities result from a cumulative effect of multiple risk factors rather than a single cause.
- Interdisciplinary and longitudinal research, including educational outcomes, is recommended for a deeper understanding of developmental disabilities.
Abstract:
The main objective was to analyze prenatal and obstetric risk factors in relation to the development of disabilities. For that purpose, data on medication, i.e., use of benzodiazepines during pregnancy, gestational weeks, mode of delivery (vaginal or cesarean section), duration of delivery, and fetal presentation were retrieved from medical records and semi-structured interviews with mothers/legal guardians. Trained professionals clinically assessed the children's developmental status (N=107). Fisher exact test with post hoc analysis of standardized residuals showed that a statistically significant number of children with multiple disabilities were born by cesarean section (z=3.7, p<0.001), prematurely (z=4.8, p<0.001), and by mothers using benzodiazepines (z=2.6, p<0.01). Children with autism spectrum disorders were more often delivered post-term (z=2.0, p<0.05) by induced delivery (z=2.9, p<0.01). Children with developmental coordination disorder were more often born post-term (z=2.2, p<0.05). As for the duration of delivery and fetal presentation, there was no statistically significant correlation with developmental disabilities. There is a cumulative risk of developmental disabilities rather than just a single risk factor. More interdisciplinary and longitudinal research on developmental disabilities, including children's educational outcomes should be conducted.
