MICH-21.3 Increase the proportion of infants who are breastfed at 1 year
About the Data: National
Description of the data source, numerator, denominator, survey questions, and other relevant details about the national estimate.
Number of caregivers of children born in a cohort year who indicate their child was breastfed any amount at 1 year of age
Number of children aged 19-35 months born in the same cohort year
- Yes
- No
- ≥1 year
- Still breastfeeding
From the 2007 through 2009 National Immunization Surveys:
[NUMERATOR:]
Was [child] ever breastfed or fed breast milk?
How old was [child's name] when (he/she) completely stopped breastfeeding or being fed breast milk?
Using a computer-generated list, the National Immunization Survey (NIS) identifies households across the United States with children aged 19–35 months and interviews the person who is most knowledgeable about the child’s immunization status (“caregiver”). Survey years are combined to calculate breastfeeding statistics by year of child’s birth (cohort) instead of the year in which the participant was surveyed. To calculate breastfeeding indicators by year of child birth, data are combined across all relevant survey years. Because children are 19—35 months of age at the time of the parent interview, each survey year represents children born over three years. For example, breastfeeding data for children in the 2006 birth cohort are obtained from NIS 2007, 2008, and 2009.
