Children in single-parent families, particularly children born to unmarried parents, are at high risk for experiencing material hardship. Previous research based on cross-sectional data suggests that father involvement, especially visitation, diminishes hardship. This article uses longitudinal data to examine the associations between nonresident fathers'(More)
The objective of this study was to examine socioeconomic (SES) gradients in infant health across a number of racial and ethnic groups in the United States. The study was based on data from a new nationally representative sample of children born in the US in 2001 (N = 8,650). The data include oversamples of several minority groups and a rich set of(More)
This study compared healthy late-preterm (34–36 week) and healthy full-term (37–41 week) singleton infants on a range of cognitive, motor, and behavioral outcomes at 2 and 4 years. Eighteen developmental outcomes were analyzed using the Early Childhood Longitudinal Survey-Birth Cohort, a nationally representative panel study. Ordinary Least Squares and(More)
I use three waves of panel data to examine the relationship between child support payments and fathers' contact with their nonmarital children. I disaggregate support into fathers' formal and informal payments and incorporate cross-lagged effects models to identify the direction of causality between payments and contact. After including the behavior from(More)
Objective The objective of this study was to examine the relationship between maternal pre-pregnancy obesity and a diagnosis of asthma in offspring at age 3 years. Methods A population-based sample of children born in large U.S. cities in 1998–2000 was followed since birth (N = 1971). The main outcome measure was whether the mother reported at 3 years that(More)
OBJECTIVES We assessed whether the association between low birthweight and early childhood asthma can be explained by an extensive set of individual- and neighborhood-level measures. METHODS A population-based sample of children born in large US cities during 1998-2000 was followed from birth to age 3 years (N=1803). Associations between low birthweight(More)
This study examines the total package of child support that mothers receive from the nonresident fathers of their children, by focusing on three components of total support: formal cash, informal cash, and in-kind support. Using the Fragile Families and Child Wellbeing Study, this article considers how contributions change over time and the effects of child(More)
There are well-documented and as yet unexplained disparities in birth outcomes by race in the USA. This paper examines the sources of disparities in low birth weight between blacks and whites in the US, by focusing on differences in disparities between two very distinct geographic areas, the Deep South and the rest of the country. Two findings from prior(More)
OBJECTIVES We examined whether food insecurity was different for children in cohabiting or repartnered families versus those in single-mother or married-parent (biological) families. METHODS We compared probabilities of child food insecurity (CFI) across different family structures in 4 national data sets: the Early Childhood Longitudinal Study-Birth(More)
We investigate the widely held premise that welfare participation causes women to refrain from marriage. Using data from the Fragile Families and Child Wellbeing study (N = 3,219), we employ an event history approach to study transitions to marriage among mothers who have had a non-marital birth. We find that welfare participation reduces the likelihood of(More)
