The CDC mPINC Survey

Maternity Practices in Infant Nutrition and Care (mPINC) is a national survey of maternity care practices and policies conducted by the CDC every two years, beginning in 2007. It is administered to all hospitals and birth centers with registered maternity beds in the U.S. 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 was administered to every facility in the U.S. that routinely provides maternity care services, and was to be completed by a key informant on behalf of his or her institution in their capacity as the person most knowledgeable about the relevant practices. The survey is administered biannually to monitor and examine changes in practices over time.


Two versions of the questionnaire were developed that were identical in content, except for minor differences in wording to reflect the relevant type of staff and type of birth facility being surveyed.
