R8: Breastfeeding

Framework Component

Population Results - Trends and Reductions in Disparities

Indicator Description

The proportion of the SNAP-Ed eligible infants that were ever breastfed, fully breastfed, or partially breastfed.

Background and Context

Breastfeeding protects infants from obesity; a meta-analysis shows the risk of childhood obesity is 22 percent lower in breastfed children than in children who were never breastfed (Yan et al., 2014). The American Academy of Pediatrics (AAP) recommends that breastfeeding continue for at least 12 months, and thereafter for as long as mother and baby desire.

The SNAP-Ed State Plan Guidance requires that breastfeeding activities must be planned and implemented in collaboration with the state WIC agency and state breastfeeding coordinator. The WIC Program should have the lead and primary role in all breastfeeding activities with SNAP-Ed supplementing existing WIC activities. SNAP-Ed can advance breastfeeding in its programming through such activities as working on lactation policies and promotion at low-wage worksites, child care facilities, or other community settings.

The five measures in R8 align with the breastfeeding goals outlined in Healthy People 2020, in maternal, infant, and children's health:

  • Increase the proportion of infants who are breastfed ever to 81.9 percent
  • At 6 months to 60.6 percent
  • At 1 year to 34.1 percent
  • Exclusively through 3 months to 46.2 percent
  • Exclusively through 6 months to 25.5 percent

Outcome Measures

Five measures of breastfeeding rates among infants:

  • R8a. Ever breastfed
  • R8b. Breastfeeding at 6 months
  • R8c. Breastfeeding at 12 months
  • R8d. Exclusive breastfeeding at 3 months
  • R8e. Exclusive breastfeeding at 6 months

What to Measure

CDC administers the National Immunization Survey, which is a nationally representative sample of all 50 states and the District of Columbia. To maximize the sample size for state-level estimates by socio-demographic categories, 3 birth years are combined for analysis. Breastfeeding indicators are calculated by year of child's birth rather than survey year. Because children are 19-35 months of age at the time of the parent interview, each survey year represents children born over 3 years, and each birth year can consist of respondent data from up to 3 survey years. SNAP-Ed agencies can use CDC state-by-state breastfeeding data listed in the Breastfeeding Report Card:

Breastfed at 6 months is defined as breastfeeding to any extent with or without the addition of complementary liquids or solids. Exclusive breastfeeding is defined as ONLY breast milk-no solids, no water, and no other liquids.

FNS also collects state and local WIC agency breastfeeding performance measurements based on program participant data of the number of partially and fully breastfed infants for each WIC state and local agency. Local agencies reporting 30 or fewer total infant participants are excluded.
