The 1988 National Health Interview Survey on Child Health (NHIS-CH) was conducted by the National Center for Health Statistics (NCHS), and cosponsored by the National Institute for Child Health and Human Development and the Health Resources and Services Administration. The U.S. Census Bureau directed field work for the survey. Every year the National Health Interview Survey (NHIS) asks a standard set of health and demographic questions about each member of sample families; in addition, one or more questionnaires on special health topics may be administered to one or more selected family members. For 1988, the NHIS focussed on the child and the supplemental section consisted of the Child Health Supplement. In addition to the Child Health Supplement the questionnaire contained items on demographic and health information for other individuals within the sample child's household. Topics covered in the 1988 NHIS-CH interview included child care, marital history of the child's parents, geographic mobility, circumstances of the pregnancy and birth, injuries, impairments, acute conditions, chronic conditions, passive smoking, sleep habits, school problems, developmental problems, and use of health care services. The resulting data set for this survey includes 1347 variables and 17,110 cases.
