Insights
Maternal folic acid (FA) supplementation during pregnancy was linked to a lower risk of autism spectrum disorder (ASD) and abnormal head circumference (HC) in offspring. This suggests FA may play a protective role in neurodevelopment.
Area of Science:
- Neurodevelopmental disorders
- Pediatric health
- Maternal health
Background:
- Autism spectrum disorder (ASD) is a complex neurodevelopmental condition.
- Abnormal head circumference (HC), including macrocephaly and microcephaly, is observed in some children with ASD.
- Maternal health status and prenatal factors are increasingly recognized as potential influences on ASD risk.
Purpose of the Study:
- To investigate the association between maternal health status during pregnancy and the risk of ASD and abnormal HC in offspring.
- To examine the specific role of folic acid (FA) supplementation during pregnancy in relation to ASD and HC outcomes.
Main Methods:
- Observational case-control study design.
- Inclusion of Han children diagnosed with ASD and typically developing (TD) controls.
- Propensity score matching and multivariate logistic regression analysis to control for confounding factors.
- Data collection via physical measurements and maternal questionnaires on risk factors and FA supplementation.
Main Results:
- Significantly higher incidence of macrocephaly (22.0% vs 1.8%) and microcephaly (17.1% vs 1.8%) in children with ASD compared to TD controls.
- Maternal FA supplementation during pregnancy was significantly associated with a reduced risk of ASD (OR=3.69) and abnormal HC (macrocephaly: OR=8.13; microcephaly: OR=4.16).
- Overall incidence of abnormal HC was higher in the ASD group than in the TD group.
Conclusions:
- Abnormal head circumference is more prevalent in children with ASD.
- Maternal folic acid supplementation during pregnancy may have a protective effect against the development of ASD and abnormal HC in offspring.
- Further research into maternal health status and its impact on ASD etiology is warranted.
Abstract:
To determine whether health status during pregnancy is associated with autism spectrum disorder (ASD) and abnormal head circumference (HC) in the offspring. This study included 41 Han children with ASD who visited the Children's Health Clinic of the Second Hospital of Shandong University between March 2018 and February 2019, and 264 Han children with typical development (TD) who visited the clinic during the same period. Physical measurements were performed on the children. The questionnaire obtained information on maternal risk factors that may be related to the increased risk of ASD and folic acid (FA) supplementation. We designed an observational case-control study using propensity score matching and multivariate logistic regression analysis. The incidence of macrocephaly in the ASD group was 22.0%, significantly higher than that in the TD group (1.8%). The incidence of microcephaly in the ASD group was 17.1% (n = 7), significantly higher than that in the TD group (1.8%). The differences between the comparisons were statistically significant. Maternal FA supplementation during pregnancy was significantly associated with ASD (P < .05), with an odds ratio (95% confidence interval of 3.69 (1.76, 7.76)). Also was associated with macrocephaly (P < .05), odds ratio (95% confidence interval) were 8.13 (1.63, 40.61) and 4.16 (1.18, 14.60), respectively. The incidence of abnormal HC was higher in the ASD group than that in the TD group. Maternal FA supplementation during pregnancy may be negatively associated with the occurrence of ASD and abnormal HC in the offspring. Further examination of the role of maternal health status in the etiology of ASD is recommended.
