For how we live.
In 415,000 New Jersey births, infants of mothers who screened positive for depression died before age one at more than three times the rate, an association steady across race, income and preterm birth.
Screening 2,904 proteins in early pregnancy, researchers found low maternal isthmin-2 was the strongest signal for later preeclampsia or fetal growth restriction, validated in two cohorts.
In 5,520 children across 34 states, prenatal exposure to regulated public-water fluoride showed no association with emotional or behavioural problems overall — with one caveat in a secondary model.
A Chinese birth cohort of 1,278 pairs found higher prenatal temperatures and heatwaves — especially in the second trimester — tracked with higher creatinine and urea in early childhood.
In 2.5 million Swedish births followed to adulthood, mothers' early-pregnancy obesity was linked to a stepwise rise in offspring cardiovascular disease, though sibling analyses temper the size.
The professional guideline now frames recovery as an ongoing process through at least 12 weeks, and one pelvic-floor study found birth injuries still resolving a full year after delivery.
Among 603 RECOVER participants, 118 were classified as likely having Long COVID. The primary analysis found no association with preterm delivery, and one secondary signal that only appeared in a sensitivity analysis.
Each 1 degree C rise in average maximum wet bulb globe temperature across pregnancy was associated with 64% higher odds of a higher stress category — an association, in one cohort, with no mechanism established.
Overall musculoskeletal injury was lower during pregnancy and the year after than in non-pregnant periods. Spine and back injuries were the exception, rising through pregnancy and postpartum.
Whole-genome sequencing of 78 families put the figure at two mutations per year of paternal age. A cohort of 40 million US births found small increases in preterm birth and gestational diabetes.
The FDA's threshold traces to a Health Canada assessment and a 2017 systematic review of 381 studies. It describes a population, not a person, and the variation between people is large.
Two cohorts published ten days apart. One found the PFAS mixture more than doubling the odds of hypertension at 24 to 28 weeks; the other found lower birth weight, but only in female infants.
Pooling under 11,000 pregnancies, a meta-analysis found no statistically significant association either way, with the three underlying studies disagreeing on which direction the risk even points.
A Finnish registry of over 123,000 women found pre-eclampsia linked to an 11% lower breast cancer risk decades later. Hormone therapy raised risk by a similar amount in both groups.
A 34-million-birth analysis maps how far smoke travels from the fires that make it. A companion review is blunt that what that exposure does, beyond the lungs, is still unsettled.
A 4.5-million-birth analysis found smoke exposure associated with higher birth weight, not lower. A separate cohort linked third-trimester smoke days to autism risk — but only when counting days, not concentration.
An analysis of 104 trials found a 10 to 20 percent reduction under some diagnostic criteria and none under UK criteria. A separate review found a GDM diagnosis is not associated with more stillbirths.
The 27 recommendations cover monitoring, diet and medication for type 1, type 2 and gestational diabetes. WHO had guidance on diabetes and guidance on pregnancy, but never on the two together.
The 162 mg group had 14.1% preterm or severe preeclampsia against 17.1% on 81 mg — a difference the trial could not distinguish from chance. Eight placental abruptions occurred on the higher dose and none on the lower.
