Importance: Investing in the next generation of researchers is essential, as recently highlighted in the 21st Century Cures Act. From its inception, the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) has supported training and career development to ensure a robust pipeline of investigators who are prepared to lead their respective fields of inquiry. In recent years, the NICHD has emphasized institutional over individual training awards to a greater degree than many other National Institutes of Health institutes of similar size...

OBJECTIVE: To evaluate whether pregnancy-associated hypertension (gestational hypertension and preeclampsia) was associated with the cardiometabolic health of young offspring. METHODS: This was a prospective observational follow-up study from 2012 to 2013 of children born to women previously enrolled in a mild gestational diabetes mellitus treatment trial or nongestational diabetes mellitus observational study. At 5-10 years after birth, children were examined and fasting blood samples obtained to determine the following cardiometabolic risk factors: blood pressure (BP), high-density lipoprotein cholesterol, triglycerides, glucose, homeostatic model assessment of insulin resistance, waist circumference, and body mass index (BMI)...

BACKGROUND: Sexually transmitted infections (STIs) including Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), Treponema pallidum (TP), and cytomegalovirus (CMV) may lead to adverse pregnancy and infant outcomes. The role of combined maternal STIs in HIV mother-to-child transmission (MTCT) was evaluated in mother-infant pairs from NICHD HPTN 040. METHODOLOGY: Urine samples from HIV-infected pregnant women during labor were tested by polymerase chain reaction (PCR) for CT, NG, and CMV...

REVIEW
Katherine L Grantz, Mary L Hediger, Danping Liu, Germaine M Buck Louis
Three recently completed longitudinal cohort studies have developed intrauterine fetal growth charts, one in the United States and two international. This expert review compares and contrasts the Eunice Kennedy Shriver National Institute of Child Health and Human Development Fetal Growth Studies, INTERGROWTH-21st and World Health Organization Multicentre Growth Reference Study conclusions in light of differences in aims, sampling frames, and analytical approaches. An area of controversy is whether a single growth reference is representative of growth, regardless of ethnic or country origin...

Sarah Hartman, Sooyeon Sung, Jeffry A Simpson, Gabriel L Schlomer, Jay Belsky
To illuminate which features of an unpredictable environment early in life best forecast adolescent and adult functioning, data from two longitudinal studies were examined. After decomposing a composite unpredictability construct found to predict later development, results of both studies revealed that paternal transitions predicted outcomes more consistently and strongly than did residential or occupational changes across the first 5 years of a child's life. These results derive from analyses of the NICHD Study of Early Child Care and Youth Development, which included diverse families from 10 different sites in the United States, and from the Minnesota Longitudinal Study of Risk and Adaptation, whose participants came from one site, were disproportionately economically disadvantaged, and were enrolled 15 years earlier than the NICHD Study sample...

BACKGROUND: Recent research indicates that the best-fitting structural model of psychopathology includes a general factor capturing comorbidity (p) and several more specific, orthogonal factors. Little is known about the stability of these factors, although two opposing developmental processes have been proposed: dynamic mutualism suggests that symptom-level interaction and reinforcement may lead to a strengthening of comorbidity (p) over time, whereas p-differentiation suggests a general vulnerability to psychopathology that gives way to increasingly distinct patterns of symptoms over time...

STUDY QUESTION: Does chronic hyperandrogenemia beginning at menarche, in the absence and presence of a western-style diet (WSD), alter ovarian and uterine structure-function in young adult rhesus monkeys? SUMMARY ANSWER: Phenotypic alterations in ovarian and uterine structure/function were induced by exogenous testosterone (T), and compounded in the presence of a WSD (T+WSD). WHAT IS KNOWN ALREADY: Hyperandrogenemia is a well-established component of PCOS and is observed in adolescent girls, indicating a potential pubertal onset of disease symptoms...

STUDY QUESTION: Does 27-hydroxycholesterol (27OH) actively facilitate the progression of luteolysis? SUMMARY ANSWER: There is increased mRNA expression of the enzyme that produces 27OH during luteolysis in vivo in rhesus macaques and sheep, and 27OH reduces progesterone secretion from human luteinized granulosa cells. WHAT IS KNOWN ALREADY: There is an increase in mRNA expression of liver x receptor (LXR) and a decrease in sterol regulatory element binding protein 2 (SREBP2) target genes during spontaneous luteolysis in primates, which could result in reduced cholesterol availability for steroidogenesis...

Sarah Hartman, Zhi Li, Daniel Nettle, Jay Belsky
A wealth of evidence documents associations between various aspects of the rearing environment and later development. Two evolutionary-inspired models advance explanations for why and how such early experiences shape later functioning: (a) the external-prediction model, which highlights the role of the early environment (e.g., parenting) in regulating children's development, and (b) the internal-prediction model, which emphasizes internal state (i.e., health) as the critical regulator. Thus, by using data from the NICHD Study of Early Child Care and Youth Development, the current project draws from both models by investigating whether the effect of the early environment on later adolescent functioning is subject to an indirect effect by internal-health variables...

Research has provided support for the dual systems model of adolescent risk taking, but the model has rarely been applied to sexual behavior. Using data from the NICHD SECCYD (N = 958; Mage = 15.07, SD = 0.18), this study examined the effects of cognitive control, reward seeking, and their interaction on sexual behavior. Results of structural equation models revealed that performance on behavioral tasks assessing reward seeking and cognitive control uniquely predicted sexual intercourse, but the interaction between them was not significant...

OBJECTIVE: To examine whether racial and ethnic differences exist in the frequency of and indications for cesarean delivery and to assess whether application of labor management strategies intended to reduce cesarean delivery rates is associated with patient's race and ethnicity. METHODS: This is a secondary analysis of a multicenter observational obstetric cohort. Trained research personnel abstracted maternal and neonatal records of greater than 115,000 pregnant women from 25 hospitals (2008-2011)...

The developmental significance of youths' racial identities during adolescence is well established. It is less clear how puberty, a normative process, influences the relationship between racial identity and adjustment outcomes during adolescence. This study examined whether puberty moderates the relationship between racial identity dimensions and internalizing and externalizing outcomes, and whether the effects of puberty and racial identity on internalizing and externalizing outcomes vary by child sex. Data are drawn from African American families (N = 176; 48% female) who participated in Waves 4 and 5 of Phase III of the NICHD SECCYD...

BACKGROUND: Lung epithelial cells express surfactant protein D (SP-D), a calcium-dependent lectin that plays an important role in antibody-independent pulmonary host defense. Previous studies have shown that it is found in the peripheral circulation in patients with pulmonary disease, likely because of translocation into the blood when lung epithelial barriers are disrupted by inflammation or acute injury. In adults, serum SP-D levels are biomarkers for the progression and severity of chronic lung disease...

BACKGROUND: Premature infants are at high risk of early-onset sepsis (EOS) relative to term infants, and most are administered empirical antibiotics after birth. We aimed to determine if factors evident at birth could be used to identify premature infants at lower risk of EOS. METHODS: Study infants were born at 22 to 28 weeks' gestation in Neonatal Research Network centers from 2006 to 2014. EOS was defined by isolation of pathogenic species from blood or cerebrospinal fluid culture at ≤72 hours age...
