The January 2013 NICHD Research Perspectives features adolescent health research undertaken by scientists in the institute’s Prevention Research Branch.

The November 2012 NICHD Director’s podcast is now online. This month’s podcast featured presenters from a recent NICHD Exchange program, “Sleep: the ABC’s of Zs.” The NICHD Exchange is a series of quarterly meetings in which NICHD administrators and scientists present relevant findings designed to spur thought provoking conversations to inform the NICHD research effort.

​Couples with high levels of PCBs and similar environmental pollutants take longer to achieve pregnancy in comparison to other couples with lower levels of the pollutants, according to a preliminary study by researchers at the National Institutes of Health and other institutions.

​Infants born to mothers attempting to deliver vaginally before the 32nd week of pregnancy are as likely to survive as those delivered by a planned cesarean, provided the fetus is in the head-first position, according to researchers at the National Institutes of Health.

​A clinic-based program for adolescents with type 1 diabetes and their families helped the teens develop the healthy behaviors needed to control their blood sugar levels, researchers at the National Institutes of Health have found.

​The August 2012 NICHD Research Perspectives, the NICHD’s monthly podcast, is now online. The August podcast features research on how the stresses of poverty may affect learning in young children, the effects of fetal alcohol exposure, and how the ability to estimate quantities changes across the lifespan.

​Most children exposed to high levels of alcohol in the womb do not develop the distinct facial features seen in fetal alcohol syndrome, but instead show signs of abnormal intellectual or behavioral development, according to a study by researchers at the National Institutes of Health and researchers in Chile.

This month, the institute launched NICHD Research Perspectives, a new podcast series. Each month, NICHD Director Alan E. Guttmacher will talk with NICHD scientists and program staff about findings from their areas of expertise. The series provides a means for researchers to go beyond the descriptions in news releases, to discuss the implications of the research, what the findings may mean for patients and members of the public, as well as what direction future studies might take.

Authors S. Katherine Laughon and Branch Ware were available last week for a news briefing to explain the results of their recent study on changing labor patterns.

Women take longer to give birth today than did women 50 years ago, according to an analysis of nearly 140,000 deliveries conducted by researchers at the National Institutes of Health. The researchers could not identify all of the factors that accounted for the increase, but concluded that the change is likely due to changes in delivery room practice.

Higher blood levels of cadmium in females, and higher blood levels of lead in males, delayed pregnancy in couples trying to become pregnant, according to a study by researchers at the National Institutes of Health and other academic research institutions.

Women who consumed a diet high in animal fat and cholesterol before pregnancy were at higher risk for gestational diabetes than women whose diets were lower in animal fat and cholesterol, according to researchers at the National Institutes of Health and Harvard University.

Newly licensed teen drivers have higher crash rates than do older drivers and the teens are much more likely to engage in risky maneuvers that increase the gravitational force on their vehicles, reported a team of scientists from the NIH and other institutions.

An NIH scientist whose landmark collaborations led to a major advance in understanding a potentially fatal disorder of pregnancy has passed away.

Taking folic acid supplements or eating fortified grain products is unlikely to worsen problems related to low levels of vitamin B12, according to researchers at the National Institutes of Health and five other institutions in the United States, Ireland and Norway.

Unlike traditional forms of bullying, youth who are the targets of cyber bullying at school are at greater risk for depression than are the youth who bully them, according to a survey conducted by researchers at the National Institutes of Health.

Researchers at the National Institutes of Health and other institutions have found that exposure to lead in childhood may delay the onset of puberty in young girls, with higher doses increasing the chance for later maturation.

Women who report feeling stressed early in their monthly cycle were more likely than those who were less stressed to report more pronounced symptoms before and during menstruation, according to a study by researchers at the National Institutes of Health and other institutions. The association raises the possibility that feeling stressed in the weeks before menstruation could worsen the symptoms typically associated with premenstrual syndrome and menstruation.

A study by researchers at the National Institutes of Health and the University of Oxford supports the widespread belief that stress may reduce a woman's chance of becoming pregnant. The study is the first of its kind to document, among women without a history of fertility problems, an association between high levels of a substance indicative of stress and a reduced chance of becoming pregnant.

National Institutes of Health researchers have shown that women's cholesterol levels correspond with monthly changes in estrogen levels. This natural variation, they suggest, might indicate a need to take into account the phases of a woman's monthly cycle before evaluating her cholesterol measures. On average, the total cholesterol level of the women in the study varied 19 percent over the course of the menstrual cycle.
