Survey description
The 1991 Longitudinal Follow-up (LF) to the 1988 National Maternal and Infant Health Survey (NMIHS) reinterviews 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 1991 LF live birth survey is a nationally representative study that examines the children of women initially interviewed for the live birth cohort of the1988 NMIHS. Its primary purpose is to obtain data on national health issues affecting children, such as child development, effects of low-birthweight, child injury, child care, pediatric care, health insurance coverage, child safety, and acute and chronic illnesses. The response rate for this survey is 89 percent. There were 8,285 completed interviews.

For the child medical provider survey, each woman was asked to provide the names of all medical providers and hospitals where her child was diagnosed, treated, and/or admitted. Each health care provider was asked to supply information on its organization, the child's health status and history, and information on each visit or hospitalization. The response rate for this survey was 89 percent for hospitals and 74 percent for pediatric care providers. Information was obtained from more than 9,000 pediatric care providers and more than 3,500 hospitals.

The fetal and infant death survey was composed of a subsample of women from the fetal death and infant death cohorts in the 1988 NMIHS. A sample of 1,000 women each from the fetal death and infant death cohorts were contacted for this survey. Its purpose was to gather information about the health of the respondents and any pregnancies experienced since their loss in 1988. The response rate for this survey was 82 percent.

The 1991 LF can be merged with the 1988 NMIHS to provide a rich longitudinal data base for maternal and child health.

Data file description
The LF consists of three public-use files. The first file contains information on the live birth survey; the second file contains information on the medical provider survey; and the third file contains information on the fetal and infant death survey.
