Overview

NISP logo 

The NISP Study, which was conducted from 1992 to 2010, is a national study of infant care practices and dissemination of infant sleep position recommendations, funded under cooperative agreement with NICHD.

Previous studies demonstrated strong associations between the prone sleep position (on the stomach) and sudden infant death syndrome (SIDS). To evaluate changes in infant sleep position following the release of infant sleep position recommendations by the American Academy of Pediatrics in 1992, and those released since then, the NISP Study examined factors that affect infant sleep-position choices made by caregivers.

The study also examined other aspects of infant sleep environment and caregiver choices for infant sleep environment, including bed sharing with adults or other household members, within the context of SIDS, entrapment, overlay, and suffocation.

The Pregnancy and Perinatology Branch (PPB) supported the NISP Study. Approximately 1,000 nighttime caregivers of infants who were age 8 months and younger were interviewed by telephone survey every year. Caregivers participating in the study were from throughout the United States.

The NISP Study is now complete. However, the dataset from the NISP Study and from another completed study, called the Collaborative Home Infant Monitoring Evaluation Study, are available to the scientific community to ensure that these important data are used to their fullest extent.

Topic Areas

The NISP Study examined factors associated with caregivers’ choices of infant sleep position, transition of infant sleep position to nonprone sleep position, and trends in bed sharing.
The NISP Study database contains data collected during the study, including, but not limited to, the following:

  • Characteristics of the infant and the sleep environment to include soft bedding and where the baby slept
  • Infant sleep position
  • Reasons for caregiver sleep position choice
  • Sleep position recommendations from specific sources
  • Sociodemographic information about the mother and the household (collected during telephone surveys)
