Does Socioeconomic Status Modify the Association Between Preterm Birth and Children's Early Cognitive Ability and Kindergarten Academic Achievement in the United States?

ABSTRACT: Being born preterm and being raised in poverty are each linked with adverse cognitive outcomes. Using data from 5,250 singletons born in the United States in 2001 and enrolled in the Early Childhood Longitudinal Study, Birth Cohort, we examined whether household socioeconomic status (SES) modified the association between preterm birth (PTB) and children's scores on cognitive assessments at age 2 years and reading and mathematics assessments at kindergarten age. Gestational age was measured from birth certificates and categorized as early preterm, moderate preterm, late preterm, early term, and term. SES was measured at age 9 months using a composite of parental education, occupation, and income. PTB was associated with 0.1- to 0.6-standard deviation-deficits in 2-year cognitive ability and kindergarten mathematics scores and with 0.1- to 0.4-standard-deviation deficits in kindergarten reading scores. Children living in the lowest (versus highest) SES quintile scored 0.6 standard deviations lower on 2-year cognitive ability, 1.1 standard deviations lower on kindergarten reading, and 0.9 standard deviations lower on kindergarten mathematics. The association between PTB and cognitive outcomes did not differ by postnatal SES. However, children who were both born preterm and lived in lower-SES households had the poorest performance on all 3 outcomes and therefore may represent a uniquely high-risk group.

Project description:Children's cognitive development and academic performance are linked to both fetal and early childhood factors, including preterm birth and family socioeconomic status. We evaluated whether the relationship between preterm birth (PTB) and first grade standardized test performance among Georgia public school students was modified by neighborhood deprivation in early childhood. The Georgia Birth to School cohort followed 327,698 children born in Georgia from 1998 to 2002 through to end-of-year first grade standardized tests. Binomial and log-binomial generalized estimating equations were used to estimate risk differences and risk ratios for the associations of both PTB and the Neighborhood Deprivation Index for the census tract in which each child's mother resided at the time of birth with test failure (versus passing). The presence of additive and multiplicative interaction was assessed. PTB was strongly associated with test failure, with increasing risk for earlier gestational ages. There was positive additive interaction between PTB and neighborhood deprivation. The main effect of PTB versus term birth increased risk of mathematics failure: 15.9% (95%CI: 13.3-18.5%) for early, 5.0% (95% CI: 4.1-5.9%) for moderate, and 1.3% (95%CI: 0.9-1.7%) for late preterm. Each 1 standard deviation increase in neighborhood deprivation was associated with 0.6% increased risk of mathematics failure. For children exposed to both PTB and higher neighborhood deprivation, test failure was 4.8%, 1.5%, and 0.8% greater than the sum of two main effects for early, moderate, and late PTB, respectively. Results were similar, but slightly attenuated, for reading and English/language arts. Our results suggest that PTB and neighborhood deprivation additively interact to produce greater risk among doubly exposed children than would be predicted from the sum of the effects of the two exposures. Understanding socioeconomic disparities in the effect of PTB on academic outcomes at school entry is important for targeting of early childhood interventions.
