Source: CDC/NCHS, NHANES 2007–2014. Estimates are percentages and 95% CIs. Labeled percentages, within a column and by covariate, without a common letter are significantly different (P < 0.05). Missing for 0–5 mo: PIR, n = 72; education, n = 232; WIC eligibility, n = 80. Missing for 6–11 mo: breastfeeding status, n = 1; PIR, n = 74; education, n = 203; WIC eligibility, n = 73. Missing for 12–23 mo: breastfeeding status, n = 3; PIR, n = 83; education, n = 251; WIC eligibility, n = 137. Differences were tested using a univariate t statistic, significance was set at P < 0.05. Estimates with — are suppressed and do not meet NCHS data presentation standards (22).

Significant quadratic trend by age group (P < 0.05).
Other race/Hispanic origin included in totals but not shown separately.
Significant linear trend by age group (P < 0.05).
The variable “Feeding Practice” was derived using 5 questions from the Diet Behavior and Nutrition Questionnaire: “Was [CHILD] ever breastfed or fed breastmilk?,” “How old was [CHILD] when he/she completely stopped breastfeeding or being fed breastmilk?,” “How old was [CHILD] when he/she was first fed formula?,” “How old was [CHILD] when he/she completely stopped drinking formula?,” and “How old was [CHILD] when he/she was first fed anything other than breast milk or formula?” Participants in all 4 categories could have consumed juice; water; other milks, including cow milk; and solids.
Significant linear trend by PIR, within each age group (P < 0.05).
