High school students who began classes roughly an hour later than students at neighboring schools slept an average of 43 minutes more per night, according to a study funded by the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), part of the National Institutes of Health. The study authors wrote that the later morning start times accommodated the teens’ natural sleep period, which begins about two hours later than that of younger children.

Research on the causes of and effective treatments for endometriosis is a high priority for NICHD. Our grantees share their findings and ongoing research.

Exercise during pregnancy stimulates fetal production of brown fat, which boosts metabolism and burns calories, even after birth, suggests a mouse study funded by the National Institutes of Health. When fed a high-fat diet, mice born to mothers who exercised had less weight gain than mice whose mothers did not exercise.

The earlier in pregnancy infants were born, the more likely they were to fail a screening test for developmental delay by age 3, according to a study by researchers at the National Institutes of Health and other institutions. Although infants born at 39 weeks, considered full term, had a lower risk than those born earlier, infants born at 40 and 41 weeks had even lower risks. The findings may have implications for elective induction—labor induced when there is no medical need—at 39 weeks.

Adolescents with chronic pain—persistent or recurrent pain for an extended period of time—may be less likely than adolescents without chronic pain to attain a high school or college degree and have a job with employer-provided benefits, according to a study funded by the Eunice Kennedy Shriver National Institute of Child Health and Human Development.

Teens with a learner’s permit who had regular, behind-the-wheel practice sessions had a lower crash risk in the year after they obtained their driver’s license, compared to teens who practiced less frequently, according to a study by researchers at the NICHD and other institutions.

Drug labels for doxycycline, clindamycin and caffeine citrate now include better information for healthcare providers on recommended usage and dosage in pediatric populations.

James A. Griffin, Ph.D., named new Chief of NICHD’s Child Development and Behavior Branch

Researchers at the National Institutes of Health have discovered a second gene that causes melorheostosis, a rare group of conditions involving an often painful and disfiguring overgrowth of bone tissue. The gene, SMAD3, is part of a pathway that regulates cell development and growth. The researchers are now working to develop an animal model with a mutant version of SMAD3 to test potential treatments for the condition.

Researchers at the National Institutes of Health have discovered in mice what they believe is the first known genetic mutation to improve cognitive flexibility—the ability to adapt to changing situations.

Researchers have developed a test to measure the expressive language skills of people with Fragile X syndrome, a genetic disorder that may result in intellectual disability, cognitive impairment and symptoms of autism spectrum disorder. Expressive language refers to the use of words to convey meaning to others. The work was funded by the Eunice Kennedy Shriver National Institute of Child Health and Human Development, part of the National Institutes of Health.

Scientists at the National Institutes of Health and other institutions have devised a new strategy to stop tumors from developing the new blood vessels they need to grow. Once thought to be extremely promising for the treatment of cancer, blocking molecules that stimulate new blood vessel growth (angiogenesis) has proven ineffective because tumor cells respond by producing more stimulatory molecules. The new strategy involves disabling key enzymes that replenish the molecule that cells need for the reactions that sustain new vessel growth.

NICHD is working with the Department of Health and Human Services and the National Institutes of Health to enhance coordinated activities addressing the problem of maternal morbidity and mortality.

Children born to women with polycystic ovary syndrome (PCOS) may be at higher risk for anxiety, attention-deficit/hyperactivity disorder (ADHD), and behavioral problems, compared to children whose mothers do not have the infertility disorder, according to National Institutes of Health researchers.

Ida S. Owens, Ph.D., was internationally known for her research advances on the genetics of drug metabolism. She also was the first African American woman to earn a doctoral degree from Duke University.

A research team funded by the National Institutes of Health has updated an online tool to provide information for clinicians and parents on outcomes for extremely preterm infants. The key change in the update was the incorporation of data from the hospital where the infant was born, which the researchers found was as important as gestational age in determining infant outcome.

Antioxidant supplements do not improve semen quality among men with infertility, according to a new NICHD-supported study.

The NIH Toolbox Cognitive Battery—an assessment of cognitive functioning for adults and children participating in neuroscience research—can be adapted to people with intellectual disabilities by modifying some test components and making accommodations for the test-takers’ disabilities, according to researchers funded by the National Institutes of Health. The adaptations ensure that the battery can be used to assess the cognitive ability of people with intellectual disabilities who have a mental age of 5 years and above, providing objective measures that could be used in a wide variety of studies.
