Measure Name

Breastfeeding

Release Date

September 16, 2024

Definition

A measure to assess whether a baby was breastfed, the duration of breastfeeding, and when solid foods were introduced.

Purpose

Breastfeeding is advantageous for both mothers and their children. Breast milk is the optimal source of nutrition for infants. Its components are easy to digest, include antibodies that can protect infants from bacterial and viral infections, and contain growth factors that may prevent chronic diseases later in life. Research indicates that women who breastfeed may have lower rates of certain breast and ovarian cancers and are more likely to return to their pregravid weight faster than those who do not breastfeed.
