Higher levels of vitamin D during pregnancy were linked to increased IQ in children.
Maternal hypothyroidism may contribute to an increased risk of ADHD in their offspring.
Women, especially minority women, from states with more restrictive reproductive rights have a greater risk of delivering a low-weight baby and face more health disparities than women who reside in states with fewer restrictions on reproductive rights.
Women who give birth to their last child later in life may have an edge when it comes to longevity. Those who gave birth later in life had longer telomeres, which are biomarkers for long-term health and longevity.
Study of pregnant mice found excess folic acid is detrimental to brain development in fetuses. Mice exposed in-utero to higher doses of folic acid had significant brain changes compared to those who were exposed to lower doses.
Women who experience unexplained repeated pregnancy loss (uRPL) process olfactory signals related to male body odor differently to other women. Those who experience uRPL are better able to identify the smell of their spouse.
Children whose mothers' used cannabis while pregnant are more likely to have an elevated risk of psychopathology during middle-school.

Study refutes any association between the H1N1 vaccine given to pregnant women and an increased risk of autism diagnosis in children.
Children born to mothers who experienced immune disorders during pregnancy, including allergies, asthma, autoimmune diseases, and autoinflammatory syndromes, are more likely to exhibit behavioral and emotional problems. The child's sex may interact with maternal immune conditions to influence the outcome of ASD symptoms. While maternal immune disorders were associated with emotional and behavioral problems in children on the autism spectrum, there was no association with reduced cognitive function.
Maternal obesity may hinder their child's brain development as soon as the second trimester of pregnancy. High maternal BMI is associated with changes to the child's prefrontal cortex and anterior insula, two brain areas associated with decision making, and behavior.
