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.

A childhood shaped by sugar rationing was linked to mental health more than 50 years later

UK Biobank researchers examined whether sugar rationing during pregnancy and the first two years of life was associated with adult sweet-food preferences, sugar intake, brain structure, anxiety, and depression.

Early-life sugar restriction may reduce dementia risk later

Consuming less sugar in utero before birth and during the first one to two years of life was associated with a lower risk of developing dementia later in life, according to a study published July 29, 2026, in Neurology, the medical journal of the American Academy of Neurology.

New study links primary infertility to accelerated reproductive aging

The average woman spends more than one-third of her life in menopause. Some women, however, must deal with menopause-related symptoms longer and face added health problems because of premature menopause (before age 40) or early menopause (before age 45).

Prenatal therapy for cystic fibrosis improves lifelong health outcomes

This Cystic Fibrosis Awareness Month, Children's Hospital Colorado (Children's Colorado) is highlighting a growing shift in care: starting cystic fibrosis treatment before birth to improve lifelong health outcomes and reduce hospital stays.

Pregnancy-related disorders may shape offspring heart health into adulthood

Hypertensive disorders in pregnancy may lead to lasting cardiovascular issues in offspring, highlighting the need for improved maternal health strategies.

Neurodegeneration in Down syndrome may begin shortly after birth

Signs of neurodegeneration in individuals with Down syndrome may start as early as birth, a critical stage of brain development, a new study shows.

Early chemical exposure linked to sperm abnormalities in men

An estimated 7% of all men are affected by infertility. Multiple animal studies indicated that exposure to persistent environmental chemicals in early life can negatively impact male reproductive health, and now a human study suggests the same.

Maternal antibodies provide lifelong protection against adult gum disease

Mothers provide a hidden immune legacy that protects their children's teeth long after weaning is over. A new study reveals how maternal antibodies act as early life architects, programming the mouth to resist aggressive bacteria and prevent the bone loss associated with adult gum disease.

Baby teeth reveal early metal exposure effects on brain

Researchers at the Icahn School of Medicine at Mount Sinai report that early-life exposure to common environmental metals may influence brain development and behavioral health more than a decade later.

Cystic fibrosis therapies significantly reduce the need for pediatric lung transplants

Pediatric lung transplant specialist Christian Benden, MD, described the future for children who need lung transplants: fewer operations overall, but more complex patients and mounting challenges for the teams who care for them. He addressed the 46th Annual Meeting and Scientific Sessions of the International Society for Heart and Lung Transplantation (ISHLT) today in Toronto.

Newborns carry antibiotic resistance genes within first hours of life

Antibiotic resistance genes (ARGs) – segments of DNA that help bacteria survive the effects of antibiotics – can be present in newborns within the first hours of life, according to research presented at ESCMID Global 2026.

SARS-CoV-2 rarely reaches first-trimester placentas but still disrupts early pregnancy immunity

Researchers analyzing 761 first-trimester pregnancies found that SARS-CoV-2 was rarely detected in placental tissues, suggesting in utero transmission early in pregnancy is uncommon. However, maternal infection was linked to immune dysregulation at the maternal-fetal interface, altered trophoblast signaling, and inflammatory changes that could affect placental development.

Maternal signals help synchronize babies’ circadian rhythms before birth

Humans and most other organisms have internal biological clocks that track the daily cycle of sunrise and sunset. These clocks help time our sleep, metabolism and other essential body functions over the course of a day, creating daily patterns called circadian rhythms.

Study reveals how hyperdiploidy creates rare pre-leukemic clones in children

B-cell acute lymphoblastic leukemia is the most common form of childhood cancer. In this type of cancer, which affects blood cells, one of the most common abnormalities is the presence of cells with an excess of chromosomes (hyperdiploidy), a condition that leads to chromosomal instability.

Crisis-driven maternal psychological stress can affect fetal development and birth outcomes

Fetal development is a critical stage with effects that can last throughout life. Yet, identifying the effects of maternal psychological stress on the fetus has been difficult, mainly because stressful events often produce psychological and physical consequences that directly affect mothers and their children.
