A meta-analysis was performed to evaluate the possible association between maternal alcohol drinking during pregnancy and autism spectrum disorder (ASD) in offspring. Twelve datasets from five observational studies were included. Results showed that maternal alcohol drinking during pregnancy was not independently associated with ASD (risk ratio:…

In the United States, most mothers work during pregnancy. Yet, until the passage of the Pregnant Workers Fairness Act in 2022, pregnant employees did not have a right to reasonable accommodations to work under safe conditions. This law is expected to increase employment among pregnant women, making it critical to understand the effects of work…

Several studies have reported an association of autism spectrum disorder (ASD) with central nervous system (CNS) infections and intrauterine infections; however, the results remain unclear. This study aimed to examine this issue using an extensive national database. Utilizing JMDC medical claims database, we conducted a retrospective cohort study…

This study investigated whether some factors regarding especially pregnancy and post-pregnancy and 0-36-month-old infants' exposure to digital screens played a role in the attention deficit hyperactivity disorder (ADHD) scores of 4-11-year-old children. The cross-sectional research method was used. The sample consisted of the mothers of 2835…

We systematically reviewed the evidence on the association between maternal folic acid supplementation and the risk of offspring's autism spectrum disorders (ASD). A total of 10 studies with 23 sub-studies (9795 ASD cases) were included. Folic acid supplementation during early pregnancy was associated with a lower risk of offspring's ASD [OR 0.57,…

We examined maternal prenatal vitamin use or supplemental folic acid intake during month one of pregnancy for association with autism spectrum disorder (ASD) in the Early Autism Risk Longitudinal Investigation, an enriched-risk pregnancy cohort. Total folic acid intake was calculated from monthly prenatal vitamins, multivitamins, and other…

The proposed study sought to investigate whether maternal experiences of racial discrimination and gendered racial stress are associated with offspring executive functioning. Total 266 Black mother-child pairs in the United States were assessed from pregnancy through child age of 4 years. We hypothesized that children whose mothers reported higher…

This meta-analysis was conducted to estimate the overall association between maternal exposure to pesticides and risk of ASD in offspring. PubMed, EMBASE, Web of Science, and the PsycINFO were searched until December 30, 2020 to include eligible studies. Eight studies with 50,426 participants, 5810 of whom had ASD, were involved in the study.…

Using National Vital Statistics Birth and Fetal Death Data from 1995 to 2020 linked to county-level information on wildfires, we use variation in wildfire timing to examine how effects of wildfire exposure on infant health vary by maternal education. Results indicate that wildfire exposure increases the likelihood of low birth weight and fetal…

Fetal androgen exposure may be associated with autism spectrum disorder (ASD). We studied 1777 mother-child pairs in the prospective Odense Child Cohort. Prenatal androgen exposure was assessed by maternal 3rd trimester testosterone concentrations, maternal polycystic ovary syndrome (PCOS), and 3 months offspring anogenital distance. ASD traits…

Despite growing interest in placental epigenetics, the combined impact of prenatal stress and socioeconomic status on placental methylation is still largely understudied. We conducted a study to examine the associations of prenatal stress and socioeconomic factors (household income, Hollingshead socioeconomic index) with placental methylation.…

Every baby brings its own temperament with it into the world. Although it is widely accepted by scientists that genetic factors are effective in the formation of temperament, this study aims to examine the possible effects of the pregnancy process on the temperament characteristics of children in line with the experiences of mothers and the role…

Prenatal and postpartum depression are highly prevalent worldwide, and emerging evidence suggests they contribute to impairments in children's executive functions. Studies of maternal depression, however, have focused on the postpartum and postnatal periods with relatively less consideration of prenatal influences on child development. This study…

Exposure to war is known to impact children's physical and mental health. Recent research reveals that war exposure might even affect the developmental outcomes of children who are yet to be conceived. In this study, we sought to extend such prior work by investigating longitudinal associations between pre-conception war exposure and the…

Prenatal folate and vitamin B[subscript 12] status have been linked to child neuropsychological development, but less is known about maternal genetic influences on this association. We conducted an exploratory longitudinal study of 181 mother--child pairs to assess whether maternal MTHFR 677C>T genotype modifies the association between maternal…
