Researchers know that children born to mothers who have depression in pregnancy are at risk for developmental delays but haven’t known why. Now, a National Institutes of Health study suggests that depression persisting after pregnancy and reduced breastfeeding may account for at least part of the increased risk. Based on their results, researchers conclude that physicians may be able to reduce this risk by offering treatment for depression both during and after pregnancy and by counseling new mothers on how to breastfeed successfully.

Science Update: Cellular metabolism regulates developmental rates, suggests NIH-funded study
Cellular metabolism helps govern the speed of embryonic development, according to an NIH funded study. Insights from the work help explain why different animal species develop at distinct rates. The findings also suggest the potential to manipulate developmental rates at the cellular level.

Science Update: NIH-funded study in mice suggests bacteria rely on metal tolerance to cause pregnancy-related infection
A bacterial species that causes chorioamnionitis—an infection of the placenta and fetal membranes that often leads to preterm birth—relies on a gene for metal tolerance to hijack immune cells, suggests a study in mice funded by the National Institutes of Health. The findings indicate that strategies to target the gene and its products could eliminate one of the most common causes of preterm birth.
Science Update: Caffeine consumption during pregnancy may lead to slightly shorter child height
Exposure to caffeine in the womb, even in small amounts, may lead to shorter height in childhood, suggests an analysis by NICHD researchers. Children of women with low caffeine intake during pregnancy were slightly shorter than their peers born to women who consumed no caffeine while pregnant. The gaps in height widened between ages 4 and 8 years.

Science Update: Placental malaria may slow glucose flow to the fetus, NIH-funded study suggests
Malaria infection of the placenta may reduce the amount of glucose that passes to the fetus, according to an NIH-funded study. The research involves a placenta on a chip model—a laboratory device incorporating placental tissue to simulate the interface between maternal blood and the outermost part of the placenta. The findings offer insight into how placental malaria may deprive the fetus of an essential nutrient and may inform the development of strategies to prevent or treat the condition.
Director's Corner: Reflecting on the Past and Looking to the Future
This October, NICHD celebrates its 60th anniversary and holds the first meeting of a new task force examining stillbirth in the United States. NICHD Director Dr. Diana W. Bianchi looks forward to future progress toward the institute’s goals of promoting healthy pregnancies, raising healthy children, and ensuring healthy and
optimal lives.
Science Update: Pregnancy-associated homicides on the rise in the United States, suggests NICHD-funded study
U.S. rates of pregnancy-associated homicide—deaths that occur among women who are pregnant or had been pregnant within one year—rose in 2020 during the COVID-19 pandemic, according to a recent NICHD-funded study.
Director's Corner: Crowdsourcing to Advance Maternal Health Research
Challenge competitions offer a mechanism to quickly bring in diverse voices and expertise to innovate and problem-solve. This month, NICHD and partners launched two challenges focused on improving our nation’s maternal health: the RADx® Tech for Maternal Health Challenge and the Connecting the Community for
Maternal Health Challenge.
Release: NIH launches $8 million prize competition to reduce maternal deaths in regions that lack maternity care
The National Institutes of Health is offering up to $8 million in cash prizes to accelerate development of technologies to improve maternal health outcomes for those who live in areas lacking access to maternity care.
Release: NIH launches challenge to advance community-based maternal health research
The National Institutes of Health has launched a $3 million challenge competition to encourage community-based and advocacy organizations in the United States to develop the infrastructure and capabilities necessary to conduct maternal health research.
Media Advisory: NIH-funded researchers develop same-day test to detect abnormal fetal chromosomes
Scientists funded by the National Institutes of Health have developed a same-day test to identify abnormal fetal chromosomes.
Item of Interest: NIH to establish Maternal Health Research Centers of Excellence
NIH recently released three funding opportunity announcements inviting applications for the Maternal Health Research Centers of Excellence initiative, which will develop and evaluate innovative approaches to reduce pregnancy-related complications and deaths and promote maternal health equity.

Science Update: Pregnant people with disabilities at higher risk for intimate partner violence, NIH-funded study suggests
Compared to pregnant people without a disability, pregnant people with disabilities may have about two and a half times the risk of experiencing intimate partner violence in the year before pregnancy and during pregnancy, suggests a study funded by the National Institutes of Health. The study authors conclude that health care providers should be vigilant in screening persons with disabilities for intimate partner violence before and during pregnancy and refer them to appropriate information and resources.
Science Update: Pfizer, Moderna COVID-19 vaccines may offer slightly greater protection during pregnancy than Johnson & Johnson vaccine, NIH-funded study suggests
The Pfizer-BioNTech and Moderna COVID-19 vaccines may offer slightly more protection during pregnancy against SARS-CoV-2, compared to the Jansen/Johnson & Johnson vaccine, suggests a study funded by the National Institutes of Health. Vaccination during the first and third trimesters appears to result in higher antibody-stimulated immune responses than vaccination in the second trimester. It also may lead to greater transfer of antibodies from maternal blood to the placenta.
Science Update: Hormone prevents obesity in offspring of pregnant mice with obesity, according to NIH-funded study
Giving the hormone adiponectin to pregnant mice with obesity prevented later life obesity and related health conditions in their offspring, according to a study funded by the National Institutes of Health. The findings suggest that adiponectin, a hormone produced by fat cells, could play a role in reducing the lifelong obesity risk of children born to mothers with obesity during pregnancy.
Science Update: Placental inflammation could explain link between air pollution and pregnancy complications, NIH-funded study in mice suggests
The increase in pregnancy complications linked to air pollution exposure could result from the pollutants’ direct effects on the placenta, suggests a study in mice funded by the National Institutes of Health. Placentas of mice exposed to a mixture of common urban air pollutants before and during pregnancy were inflamed and had a loss of blood vessel cells. The study authors say the findings could provide insight into how air pollution might affect pregnancies and lead to strategies for preventing pregnancy complications.
