National Health Interview Survey, 1990: Health Promotion and Disease Prevention (HPDP) Pregnancy and Smoking Supplement

The basic 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. The purpose of this supplement was to estimate women's current smoking practices and to measure knowledge of the effects of cigarette smoking on certain health problems, pregnancy, and childbirth. The file contains approximately 90 variables from the core file (see NATIONAL HEALTH INTERVIEW SURVEY, 1990 [ICPSR 9839]), including sex, age, race, marital status, veteran status, education, income, industry and occupation codes, and limits on activity. Variables unique to this supplement include questions on current pregnancy status, whether the respondent had ever smoked 100 cigarettes, whether she currently smoked, time elapsed since the respondent last smoked regularly, number of cigarettes the respondent smoked per day, whether the respondent smoked during pregnancy, number of cigarettes smoked before learning of pregnancy, number of cigarettes smoked after learning of pregnancy, whether the respondent smoked during most of their last pregnancy, and whether the respondent was ever advised by a doctor to quit smoking.
