To help spur innovation against a growing maternal health crisis, NICHD launched the Decoding Maternal Morbidity Data Challenge last year. Learn about the winning proposals.

Researchers funded by the National Institutes of Health have developed a prototype genetic test with the potential to predict the development and eventual severity of uterine fibroids—benign, but sometimes painful and debilitating tumors of the uterus. The test could be used to identify fibroid cases early and to better understand how they develop and how to treat them.

NIH-funded study compared more than 1.1 million students across nine states.

Life-threatening pregnancy complications known as severe maternal morbidity (SMM) appear to be associated with an increased length of hospital stay for infants and an increase in the cost of caring for them, suggests a study funded by the National Institutes of Health. The findings support the hypothesis that infants of mothers with SMM may also be at risk for severe complications. The authors concluded that helping patients to reduce their risk factors—in early pregnancy or before conception—may reduce the chances for SMM and improve the health of infants.

The COVID-19 pandemic has magnified mental and emotional health challenges for all of us. Dr. Bianchi highlights research to understand and address factors affecting the mental health of children and their parents.

Children who were first given juice before they were six months old were more likely to have overweight or obesity in early and mid-childhood, compared to kids who were given juice at one year old or later, according to a study by researchers at the National Institutes of Health. The finding provides additional support for a theory that giving young children sweet foods or drinks may foster a preference for sweet tastes that can lead to weight gain later in childhood.

In the United States, more than 20 percent of deaths during pregnancy and the first year after childbirth are due to drug use, suicide, or homicide, an NICHD-funded study suggests. The number of pregnancy associated deaths from these causes increased between 2010 and 2019, with drug-related deaths nearly tripling.

Vaccinating women against SARS-CoV-2 in mid to late pregnancy could provide their infants at least some protection against COVID-19 through six months of age, suggests a small study funded by the National Institutes of Health. Compared to infants born to mothers who had COVID-19 during pregnancy, infants born to vaccinated mothers were much more likely to have antibodies against the virus.

Dr. Una Grewal, director of NICHD’s intramural Division of Population Health Research, worked in academia, the corporate world, and state and federal government agencies prior to settling into a leadership role in science administration. Read about how she shaped her unique career path.

Pregnant women with COVID-19 appear to be at greater risk for common pregnancy complications—in addition to health risks from the virus—than pregnant women without COVID-19, suggests a study funded by the National Institutes of Health.

On average, scores on development tests were lower for infants born earlier in the range of a term pregnancy—from 37 to 41 weeks—than for those born later in the range, suggests a study by researchers at the National Institutes of Health. The slight difference in scores, first apparent at eight months, persisted through age seven. The findings may have implications for current practice guidelines recommending induction of labor for non-medical reasons at the 39th week of pregnancy.

How early can a baby be born and not only survive but thrive? Dr. Bianchi discusses continued progress in saving extremely preterm infants and highlights NICHD’s efforts to prevent preterm births and improve the care of premature babies.

Infants born during the pandemic—regardless of whether their mothers had COVID-19 during pregnancy—scored slightly lower on certain tests of neurodevelopment at 6 months old, compared to a similar group of infants born before the pandemic, according to a study funded by the National Institutes of Health. The findings suggest that children born during the pandemic may need long-term monitoring to rapidly identify any future lags in development. The researchers theorized that maternal stress resulting from the pandemic could have effects on children’s neurodevelopment.

Women who breastfed for two years or longer had higher blood levels of anti-Müllerian hormone and later onset of menopause, compared to women who breastfed for one month or less, according to an NICHD-supported analysis. The findings also suggest that previously observed relationships between menopause timing and the number of times a woman gave birth may be largely attributable to breastfeeding.

A new study funded by the National Institutes of Health contradicts the current recommendation that women with obesity should lose weight before trying to conceive. The study of more than 300 women with obesity found no difference in the proportion of live births among women with unexplained infertility who lost weight before infertility treatment and a similar group who did not lose weight before treatment.

Taking supplemental docosahexaenoic acid (DHA) during pregnancy may decrease the risk of preterm birth. A new NICHD-supported study offers a potential explanation for this effect by suggesting that a daily 1,000-milligram dose of DHA influences certain inflammatory immune responses linked to childbirth.

COVID-19 vaccination does not affect the chances of conceiving a child, according to a study of more than 2,000 couples that was funded by the National Institutes of Health. Researchers found no differences in the chances of conception if either male or female partner had been vaccinated, compared to unvaccinated couples. However, couples had a slightly lower chance of conception if the male partner had been infected with SARS-CoV-2 within 60 days before a menstrual cycle, suggesting that COVID-19 could temporarily reduce male fertility.

Small NIH study contributes to understanding of COVID-19 during pregnancy.

The survival rate of extremely preterm infants born from 2013 through 2018 in a large network of U.S. research centers improved to 78.3%, compared to 76% for infants born in the network from 2008 to 2012, according to researchers funded by the National Institutes of Health.

An individual’s risk for death by suicide may begin before they are born, suggests a study by researchers at the National Institutes of Health. The authors compared pregnancy and birth records of nearly 50,000 individuals born between 1959 and 1966 to death records through 2016. They found that suicide rates were higher for males, white people, and for those who were among the younger siblings in a family. Other risk factors included having a parent with less than a high school education, having a parent who worked a manual labor job, and having a mother with a high rate of pregnancy complications or who smoked during pregnancy.
