Values are adjusted RRs (95% CIs) unless otherwise indicated. Modified Poisson regression models adjusted for maternal education, employment, race/ethnicity, marital status, equivalized household income, smoking during pregnancy, delivery year, child sex, weight-for-gestational age status, and ever breastfed.

Percentages are weighted for the survey sampling design. Sample sizes are not weighted and refer to the number of mother-child pairs.
