PURPOSE: : The purpose of this study was to explore the influence wealth has on cognitive development in 2-year-old children who were born preterm, and to determine whether racial/ethnic differences in wealth explained disparities in cognitive development. SUBJECTS: : A nationally representative sample of 1400 children who were born between 22 and 36 weeks' gestation. DESIGN: : Cohort study. METHODS: : Secondary data analysis of the Early Childhood Longitudinal Survey-Birth Cohort (ECLS-B). The ECLS-B was a prospective national longitudinal study of infants born in the United States during the calendar year 2001 drawn from birth certificates in the United States. MAIN OUTCOMES: : The impact wealth (parental homeownership and investments) had on cognitive development at 2 years and whether wealth eliminated the cognitive disparity seen between white, African American, and Hispanic children. PRINCIPAL RESULTS: : Wealth (homeownership and investments) did not have an independent effect on cognitive development, but it did eliminate the disparity between white children and African American children (P >/= .05). However, wealth did not eliminate the disparity in cognitive development between white children and Hispanic children. Hispanic children scored 3.91 points lower than white children (P
