1Formula supplementation is defined as supplementation of
breast milk with formula (with or without other supplementary liquids or
solids) among infants breastfed at the age specified (48 hours, 3
months, or 6 months). The denominator for the 2 day, 3 month, or 6 month
rate is the number of infants breastfeeding at 2 days, 3 months, or 6
months, respectively. 2WIC = Special Supplemental Nutrition Program for Women, Infants, and Children. 3Unmarried includes never married, widowed, separated, divorced. 4MSA = Metropolitan Statistical Area defined by the Census Bureau. 5Poverty Income Ratio = Ratio of self-reported family income to the federal poverty threshold value depending on the number of people in the household. Source: National Immunization Survey, Centers for Disease Control and Prevention, Department of Health and Human Services Sample sizes appearing in the NIS breastfeeding tables are slightly smaller than the numbers published in other NIS publications due to the fact that in the DNPAO breastfeeding analyses, the sample was limited to records with valid responses to the breastfeeding questions. |
