Early education and health outcomes of a 2001 U.S. birth cohort.

This paper looks at health outcomes, health behaviors, and health screening with respect to participation in Early Childhood Care and Education. With information on health status at multiple periods in time, we are able to look at whether healthier children select into early childhood education (as measured by center-based preschool care and Head Start), as well as whether early childhood education has immediate and near-term effects on a range of health status measures. There is some evidence that child obesity is ameliorated by participation in center-based preschool or Head Start and this finding is supported by clear evidence of improved nutrition and increased levels of health screening. Effects on other health outcomes such as asthma, ear infections, and respiratory problems may be partially masked by unobserved heterogeneity.
