Notes:

¹The restricted samples of ECLS-K and ECLS-B are retricted to children whose mother was non-Hispanic white, non-Hispanic black, or Hispanic; they thus exclude children whose mother was non-Hispanic Asian or non-Hispanic other (i.e., American Indian/Alaskan Native, Native Hawaiian Pacific Islander, and more than one race). All regressions are unweighted.

²Mother’s weight status in the ECLS-B is calculated from reported height and weight; mother’s weight status in the ECLS-K is imputed.

³All observations are rounded to comply with NCES disclosure guidelines.
