What mothers eat in pregnancy may shape a child’s weight years later

A prospective study of 252 mother-child pairs found that higher combined maternal fruit and vegetable intake during pregnancy was associated with lower odds of overweight or obesity in children at age four. Total and natural fruit juice showed no association, whereas higher commercial fruit juice intake was associated with increased odds, though the authors emphasized that this finding was exploratory.

What four pregnancy eating patterns revealed about mothers and newborns

Researchers analyzing 1,404 pregnant women in Germany identified four distinct dietary patterns that differed substantially in maternal BMI, socioeconomic status, age, and gestational weight gain. A vegetable-rich pattern was also associated with selected neonatal measures, including greater birth length, but most newborn associations were modest or nonsignificant, and the observational study cannot establish causality.

Researchers found one childhood behavior linked to folic acid use before pregnancy

Researchers analyzed 646 children aged 2–8 years and their 563 mothers to examine whether maternal folic acid supplementation before conception was associated with childhood behavioral difficulties. Preconception supplementation was associated with a 34% lower risk of peer relationship problems, while no significant associations were found for total behavioral difficulties, emotional, conduct, hyperactivity/inattention, or prosocial problems.

Breastmilk from cannabis users showed differences, but cannabis may not be the whole story

A narrative review found that maternal cannabis use may be associated with differences in breastmilk fat, protein, lactose, and the immune factor secretory immunoglobulin A, but evidence comes primarily from only two human studies and remains limited and inconsistent. The authors stress that maternal diet, food security, socioeconomic circumstances, and other forms of adversity could confound these associations and should be incorporated into future research.

Prenatal strength training may help reduce the risk of gestational diabetes

Various forms of physical exercise may help prevent diabetes during pregnancy (or gestational diabetes), but data are limited. In a randomized clinical trial published in Acta Obstetricia et Gynecologica Scandinavica including 209 pregnant women, participants who followed a strength training program from gestational weeks 12–14 until week 36 or delivery had lower rates of gestational diabetes.

Prenatal exposure to higher water fluoride levels associated with lower child cognition

Pregnant mothers who lived in neighborhoods where public drinking water fluoride levels were near or above the current U.S. recommended levels tended to have children who scored lower on tests of fluid reasoning as fluoride levels increased, according to a new study supported by the National Institutes of Health's Environmental influences on Child Health Outcomes (ECHO) Program.

Two early-life findings stood out in children who later screened positive for autism risk

Children born very preterm were more likely than term-born children to screen positive for autism risk at age 5 using the Social Communication Questionnaire. Among very preterm children, cerebellar abnormalities at term-equivalent age and moderate-to-severe histologic chorioamnionitis were independently associated with higher autism screening risk, alongside male sex and higher social risk.

Rising wildfire smoke in the US offsets improvements in prenatal health

Wildfires are well-known health risks. Now, in a new Frontiers in Environmental Health study, researchers in the US have – for the first time – evaluated how prenatal PM2.5 exposure has changed over space and time on a national scale, and what role wildfires play in shaping these trends.

Sensitive parenting buffers against child ADHD risks from pregnancy

Research from Oregon Health & Science University's Center for Mental Health Innovation provides new evidence that the way caregivers interact with children when they're very young can protect against the negative effects of inflammation during pregnancy, including increased attention-deficit/hyperactivity disorder, or ADHD, symptoms in children.
