Research finds that SSRIs during pregnancy increase gestational diabetes risk in newborns but lower preterm birth and low birth weight risks. SSRIs also associated with breathing problems and neonatal care needs in newborns.
The study found increased requests for medication abortion among adolescents in states with gestational bans and parental consent requirements. Young adults also sought more medication abortion services post-Dobbs, with the highest demand in states with restrictive abortion laws.
A preclinical study shows that cannabidiol restores emotional behavior, reduces alcohol-related vulnerability, and reverses gut microbiota alterations caused by prenatal alcohol exposure. Female mice particularly benefited from CBD treatment, which normalized their emotional alterations and eliminated vulnerability to alcohol addiction.
A cohort study found higher fine particulate matter (PM2.5) exposure associated with lower birth weight, particularly in early and mid-pregnancy.

A recent USC study found associations between increased exposure to wildfire smoke and heat stress during preconception and the first trimester with the odds of having a small-for-gestational-age infant. Living in a climate-vulnerable neighborhood can increase these risks, particularly for women exposed to heat stress.
A systematic review found a moderate risk of preterm birth, low birth weight, and infant death associated with cannabis use during pregnancy. Researchers recommend reducing cannabis use as a harm-reduction approach to mitigate risks.

Eight low-cost interventions can prevent an estimated 566,000 stillbirths and 5.2 million babies born preterm or small for gestational age each year. Implementing these interventions in 81 low- and middle-income countries could save the lives of millions of babies and improve long-term health outcomes.
A novel technique of three-dimensional (3D) slice-to-volume (SVR) MRI allows for precise delineation and measurement of the fetal optic pathway (FOP). The study found that FOP was visualized in 9 cases in unprocessed fetal MRIs, compared to 55 cases in 3D SVR images.

A new WVU study found nearly one in eight West Virginia infants had in utero exposure to opioids, stimulants, and/or cannabis between 2020 and 2022. The study showed a 40% increased risk of preterm birth among infants exposed to stimulants alone and a 70% increase with concurrent stimulant and cannabis exposures.
Women who experience five major pregnancy complications face an increased risk of ischemic heart disease up to 46 years after delivery. The study found that all major adverse pregnancy outcomes should be recognized as lifelong risk factors for heart disease.
A new study reveals that US pregnancies are shorter than those in England and the Netherlands, with average lengths declining by over half a week between 1990 and 2020. This finding suggests that reducing medical interventions during the birthing process could improve maternity care outcomes in the US.
Researchers found that buprenorphine use was associated with better outcomes for the baby, including lower risk of preterm birth, small size for gestational age, and low birth weight. The study suggests increasing access to buprenorphine treatment among pregnant individuals with opioid-use disorder.
A Norwegian study of over 72,000 births found no increased risks of adverse outcomes for babies conceived within three months of a miscarriage or abortion. In fact, shorter intervals were associated with lower risks of small for gestational age and large for gestational age, as well as lower risk of gestational diabetes.
A large Nordic study found that children born to mothers with preeclampsia have higher risk of ischemic heart disease and stroke. The association holds even after accounting for other birth complications such as preterm birth and low birth weight.
