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.

It just got easier to participate in the PregSource®: Crowdsourcing to Understand Pregnancy research project. The free app allows participants to track their weight, sleep, mood, and other features of their pregnancy in just a few taps.

As we usher in November and Thanksgiving, it’s a fitting time to reflect on NICHD’s commitment to research on nutrition.

No serious adverse events were reported by 180 breastfeeding women receiving either the Pfizer or Moderna vaccine, either among themselves or in their infants, according to a study funded by the National Institutes of Health. For the mothers, adverse events included muscle and body aches, fever and vomiting, pain, redness, swelling, or itching at the injection site.

Current vaccines to prevent COVID-19 are highly effective in producing antibodies in pregnant people, resulting in more antibodies than what is generated from a natural SARS-CoV-2 virus infection, according to a study funded by the National Institutes of Health. Moreover, antibodies produced after vaccination are present in breastmilk and travel across the placenta, indicating that vaccination during pregnancy will also confer immunity to newborns.

For many COVID-19 patients, full recovery remains elusive even long after they should feel “better.” NIH recently announced research opportunities to understand COVID-19 long haulers, who have what researchers now refer to as Post-acute sequelae of SARS-CoV-2 infection (PASC). NICHD joins these opportunities while remaining focused on PASC patients within our audiences of interest—pregnant and lactating people, children, and those with disabilities.

A new study funded by the National Institutes of Health will evaluate the effects of remdesivir in pregnant women who have been prescribed the drug to treat COVID-19. The study, which will be conducted at 17 sites in the continental United States and Puerto Rico, aims to determine how pregnant women metabolize the drug and whether there are any potential side effects.

Pregnant people need to be protected through research rather than from research, the authors contend.

As the COVID-19 pandemic persists, SARS-CoV-2 vaccines offer the potential to halt the spread of the virus. Yet, we know very little about the effectiveness and safety of the vaccines during pregnancy.

Vegetarian diets during pregnancy are associated with small infant birth weight, but not a higher risk preterm birth or other medical complications, suggests a National Institutes of Health study.

Human milk oligosaccharides found in breastmilk may influence a child’s growth from infancy through early childhood, according to an NICHD-supported study.

The longer a woman with gestational, or pregnancy-related, diabetes breastfeeds her infant, the lower her risk for developing type 2 diabetes later in life, suggests an analysis by researchers at the National Institutes of Health and other institutions.

To expand the reach of its crowdsourcing pregnancy research project, the National Institutes of Health (NIH) recently launched a Spanish version of PregSource®.

Women who breastfed their infants exclusively for 7 to 12 months may have a significantly lower risk of early menopause than their peers who breastfed their infants for less than a month, according to an analysis funded by the National Institutes of Health.
