National Maternal and Infant Health Survey (NMIHS)

The objective of the National Maternal and Infant Health Survey (NMIHS) was to collect data needed by Federal, State, and private researchers to study factors related to poor pregnancy outcomes, including low birthweight, stillbirth, infant illness, and infant death. The NMIHS was a followback survey -- it followed back to informants named on vital records. The 1988 survey expanded on information available for birth, fetal death, and infant death vital records and was the first national survey that included data on those three pregnancy outcomes simultaneously. The NMIHS provided data on socioeconomic and demographic characteristics of mothers, prenatal care, pregnancy history, occupational background, health status of mother and infant, and types and sources of medical care received.
