National Natality Survey/National Maternal and Infant Health Survey (NMIHS)


The National Natality Surveys, conducted in 1963, 1964-66, 1968-69, 1972, and 1980 were early studies on maternal and infant health. A National Fetal Mortality Survey was done in 1980, and a National Infant Mortality Survey was conducted in 1964-66. The National Maternal and Infant Health Survey NMIHS follows back informants named on vital records, providing 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.

The 1991 Longitudinal Follow-up (LF) to the 1988 NMIHS re-interviewed women who were respondents to the NMIHS to provide information on a number of areas related to child health and development. The 1991 LF consists of three parts: the live birth survey, the child medical provider survey, and the fetal and infant death survey. The live birth survey includes information on chronic and acute illnesses, immunizations, and over-the-counter medication and supplement use. The medical provider survey contains information on diagnoses made at pediatric visits or during hospitalization and on any medications provided. The live birth survey has 8,285 completed interviews, the medical provider survey has information from more than 9,000 pediatric care providers and more than 3,500 hospitals, and the fetal and infant death survey has approximately 800 records. The 1991 LF can be merged with the 1988 NMIHS. Data files for the survey are publicly available in CD-ROM format, which comes with the Statistical Export and Tabulation System (SETS) retrieval software.
