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.

Researchers at the National Institutes of Health believe they have discovered how influenza viruses open a hole in the cell membrane to inject genetic material into the cell. The findings may inform the development of new technologies to combat infectious microbes and to insert medications, genes, and proteins into cells to treat diseases.

A safe, highly effective, reversible method of male contraception would fill an important public health need. Additionally, multipurpose prevention technologies (MPTs)—products that prevent both pregnancy and sexually transmitted infections—would increase sexual and reproductive health options for both women and men. NICHD supports a broad range of contraceptive research, including efforts to develop male contraceptives and MPTs.

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.

Poverty, combined with other types of adversity in early childhood, is associated with greater chances of premature death in adulthood, compared to other adverse childhood experiences, according to a study of more than 46,000 people by researchers at the National Institutes of Health.

Maternal obesity before pregnancy may increase the risk of asthma in early childhood, suggests a study by the National Institutes of Health. Children born to mothers with obesity were more likely than those born to mothers without obesity to have persistent wheezing, an indication of asthma.

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.

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.

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.

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.

Pregnant women with disabilities have a much higher risk for severe pregnancy- and birth-related complications and death than other pregnant women, according to findings by researchers at the National Institutes of Health. Appearing in JAMA Network Open, the analysis of more than 223,000 deliveries in 19 U.S. hospitals found that roughly 2,199 women had a disability.
