Maternity Practices in Infant Nutrition and Care (mPINC) Survey

The CDC mPINC Survey

mPINC Update

The mPINC survey is currently being revised. The next survey launch is planned for 2018. More details will be provided when available.



Hospital routines can help or hinder new mothers and babies while they’re learning to breastfeed. CDC’s national survey of Maternity Practices in Infant Nutrition and Care (mPINC) is administered every two years to monitor and examine changes in practices over time at all hospitals and birth centers with registered maternity beds in the United States and Territories.


In October 2003, CDC convened an expert panel of researchers with specific experience in surveillance and monitoring of hospital practices related to breastfeeding. At the time, no system in the U.S. collected nationally representative data on these practices.

The Expert Panel’s recommendation was to establish an ongoing, national system to monitor and evaluate hospital practices related to breastfeeding among all facilities that routinely provide intrapartum care in the U.S.

In 2007, CDC administered the first national survey of maternity practices related to breastfeeding, known as the mPINC survey. It is administered every two years to every facility in the U.S. that routinely provides maternity care services, and is completed by a key informant on behalf of his or her institution in their capacity as the person most knowledgeable about the relevant practices.
