The authors analyzed Illinois vital records to determine the intergenerational birth weight patterns among the descendants of US-born and foreign-born White and African-American women. Among the descendants of the generation 1 US-born White women (n = 91,061), generation 3 females had a birth weight 65 g more than that of their generation 2 mothers (p < 0.0001); generation 3 infants had a 10% l...

BACKGROUND Most studies have not demonstrated improved survival after prenatal diagnosis of critical congenital heart disease, including hypoplastic left heart syndrome (HLHS). However, the effect of delivery near a cardiac surgical center (CSC), the recommended action after prenatal diagnosis, on HLHS mortality has been poorly investigated. METHODS AND RESULTS Using Texas Birth Defects Regis...

background: nowadays there is a strong tendency for early bathing of healthy newborns but little is known about the ther mal stability of newborns in response to early bathing. the aim of this study was to compare the thermal effect of bathing on healthy newborn within 1-2 h of life versus 4-6 h after birth. methods: in this randomized comparative study 100 healthy newborns in a newborn nursery...

OBJECTIVE The interval between births is associated with child survival in the developing world. We aimed to investigate associations between use of depot-medroxyprogesterone acetate and other reversible contraception and short birth intervals in sub-Saharan Africa. METHODS Data from successive Demographic and Health Surveys undertaken in nine African countries were analyzed. Logistic regress...

OBJECTIVE Previous studies have shown mixed results for pregnancy outcomes after loop electrosurgical excision procedure (LEEP); however, evidence is lacking regarding the pregnancy outcome of spontaneous abortion with respect to time elapsed from LEEP to pregnancy. We investigated risks of spontaneous abortion and preterm birth as they relate to time elapsed from LEEP to pregnancy. METHODS A...

Researchers have suggested that maternal hypertensive disorders during pregnancy affect fetal growth. The authors examined the associations between systolic and diastolic blood pressures in different trimesters of pregnancy and both repeatedly measured fetal growth characteristics and the risks of adverse birth outcomes. The present study (2001-2005) was performed in 8,623 women who were partic...

The predictive-adaptive response paradigm postulates that slow fetal growth advances puberty as a life-history strategy for reproductive success, when constraints on postnatal growth are minimal. The authors examined the association of birth weight for gestational age and small for gestational age (SGA) status (birth weight for gestational age <10th percentile, 6.9%) with clinically assessed ag...

OBJECTIVES We examined abruption risk in relation to change in paternity, and evaluated if birth interval confounds this association. SETTING Population-based study of singleton births in Norway between 1967 and 2009. PARTICIPANTS Women who had their first two (n=747 566) singleton births in the Norwegian Medical Birth Registry. The associations between partner change between pregnancies an...

OBJECTIVE To explore the association between race and preterm birth among women with a lifelong residence in high-income neighborhoods. METHODS Stratified and multivariable logistic regression analyses were performed on the Illinois transgenerational birthfile (infants born 1989-1991 and mothers born 1956-1975) with appended US Census income data. African American (n = 777) and non-Hispanic W...
