National Health Interview Survey, 1991: Pregnancy and Smoking Supplement (ICPSR 6138)
The purpose of the National Health Interview Survey (NHIS) is to obtain information about the amount and distribution of illness, its effects in terms of disability and chronic impairments, and the kinds of health services people receive. This supplement includes variables from the core Person File (see NATIONAL HEALTH INTERVIEW SURVEY, 1991 [ICPSR 6049]), including sex, age, race, marital status, veteran status, education, income, industry and occupation codes, and limits on activity. The variables unique to this supplement, which surveyed women aged 18-49, cover two major areas: pregnancy and smoking. Each respondent was asked about whether she had had a live birth in the last five years, and the month and year of the child's birth. Questions were also asked on breast-feeding, including length of time the child was breast-fed, period when breast milk was the child's only food, and age of the child when breast-feeding stopped. With respect to smoking, respondents were asked about the number of cigarettes they had smoked during their lifetime, whether they smoked last year, whether they currently smoked, and whether they smoked daily. In addition, respondents were queried about whether they had ever quit smoking for one day or more, whether they had quit smoking during the last 12 months, the number of times they had quit smoking during the last 12 months, and why they had stopped smoking.
The public-use data files in this collection are available for access by the general public. Access does not require affiliation with an ICPSR member institution.

Geographic Coverage: United States
Per agreement with NCHS, ICPSR distributes the data file(s) and technical documentation in this collection in their original form as prepared by NCHS.
Extent of Processing: ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:
- Standardized missing values.
Restrictions: In preparing the data tape(s) for this collection, the National Center for Health Statistics (NCHS) has removed direct identifiers and characteristics that might lead to identification of data subjects. As an additional precaution, NCHS requires, under section 308(d) of the Public Health Service Act (42 U.S.C. 242m), that data collected by NCHS not be used for any purpose other than statistical analysis and reporting. NCHS further requires that analysts not use the data to learn the identity of any persons or establishments and that the director of NCHS be notified if any identities are inadvertently discovered. ICPSR member institutions and other users ordering data from ICPSR are expected to adhere to these restrictions.
