NOTE: Means, standard errors, and percentiles were calculated with WesVar Complex Samples 3.0. Children fed human milk and females who had “blank but applicable” pregnancy and lactating status data or who responded “I don’t know” to questions on pregnancy and lactating status were excluded from all analyses.

a M = male, F = female, P/L = pregnant and lactating.

b SEM = standard error of the mean.
