Study reveals long-term, intergenerational impacts of severe preconception trauma

Can the trauma of a parent rewrite the mental health of a child born decades later? A new compelling study reveals that children born decades after the Holocaust to parents who were older than age five at the time of the initial Nazi persecutions faced elevated schizophrenia risk.

Study reveals double burden of malnutrition among low-income urban children in India

Children growing up in a low-income urban community in Vellore are now facing two seemingly opposite forms of malnutrition simultaneously: persistent thinness and rising obesity by the time they reach primary school age.

Umbilical cord proteins may explain lifelong health effects of low birth weight

Researchers have long sought to discover why babies who weigh less than expected at birth, a condition known as small for gestational age, or SGA, are at higher risk for heart, lung and metabolic diseases as adults.

Genetics play a bigger role than pregnancy in childhood obesity risk

Genetic factors primarily explain the link between parental and childhood BMI, with maternal obesity impacting birth weight more than later childhood obesity.

Recognizing perinatal heart failure early reduces life-threatening risks

Early detection and timely treatment of heart failure in pregnant or postpartum women are crucial to prevent serious complications, such as irregular heartbeat, stroke and death, according to a new American Heart Association scientific statement, "Heart Failure Occurring in the Perinatal Period."

Parental genes rather than pregnancy weight influence childhood body mass index

The link between parents' body mass index (BMI) and their children's BMI in childhood is driven largely by genetic inheritance, rather than by any direct biological effects of parental weight during pregnancy, a new study suggests.

Survey reveals critical knowledge gaps in maternal health recommendations

Most Americans know that how well a mother takes care of herself before and during pregnancy affects the health of a baby, but many people remain unclear about some specific maternal health recommendations, including when to start avoiding alcohol, according to a new nationally representative survey from the Annenberg Public Policy Center (APPC) of the University of Pennsylvania.

Immediate kangaroo mother care boosts survival for premature infants

Preterm birth and low birth weight remain major contributors to neonatal death and long-term developmental challenges.

Early pregnancy interventions improve healthy gestational weight gain outcomes

Both too little and too much weight gain during pregnancy are associated with serious maternal and child health outcomes, including preterm birth, low birth weight, death, preeclampsia, and unplanned cesarean delivery.

Elevated blood glucose during pregnancy signals a significantly higher future diabetic risk

Gestational diabetes is a strong risk factor for future type 2 diabetes, even in women with normal pre-pregnancy weight, according to a study at the University of Gothenburg. The researchers call for earlier testing and better follow-up.

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.

Early protein and calorie supplements lead to fewer high-risk newborns

In parts of the world where daily nutrition is unstable, pregnancy and newborn health are more precarious. A new study led by epidemiologist Dongqing Wang of the George Mason University College of Public Health adds to the evidence that improving maternal nutrition during pregnancy may be a key intervention to improve birth outcomes.

Mental disorders affect one in three pregnant women, and violence may be a key driver

A systematic review and meta-analysis of 18 studies involving 17,380 pregnant women found that common mental disorders affected about one-third of participants across studies from Africa, Asia, and South America. The analysis found strong regional variation and identified intimate partner violence as the only statistically significant risk factor, with affected women having about 2.6-fold higher odds of CMDs.

Study traces adult heart disease risk back to the womb

A child's future heart health may be partially shaped before they are born, reports a new Northwestern Medicine study that found pregnancy complications are linked to poorer cardiovascular health in offspring more than 20 years later.

Birth weight predicts kidney function during endurance exercise

Researchers investigate how birth weight determines kidney function changes following prolonged physical activity in different environmental conditions.

Study suggests birth weight affects kidney resilience in ultramarathon athletes

A new study is raising questions about whether human endurance has biological limits shaped long before adulthood-possibly beginning at birth.

Maternal weight before pregnancy may shape toddlers’ development

A nationwide Korean cohort study of 258,367 mother-child pairs found that maternal pre-pregnancy BMI was associated with developmental delay risk in children aged 18 to 36 months. Children of underweight mothers showed modest early risks that later attenuated, while obesity-related risks persisted across developmental domains.

Breastfeeding’s link to teen cognition emerges after researchers account for family background

A national study of 5,436 Chinese youths found that longer breastfeeding was not linked to cognition before adjustment, but was associated with modestly better math and word-recognition scores after socioeconomic factors were considered. The findings suggest that family socioeconomic patterns can mask breastfeeding-cognition associations, especially in settings where longer breastfeeding is more common among lower-SES households.
