Cigarette Smoking Cigarette smoking and related tobacco use are measured in several different data systems, including the
Persons who smoked 100 cigarettes and who now smoke every day or some days
are defined as current smokers. Before 1992 current smokers were
identified based on positive responses to the following two questions: In 1992 the definition of current smoker in the NHIS was modified to specifically include persons who smoked on "some days." (revised definition). In 1992 cigarette smoking data were collected for a half-sample with half the respondents (one-quarter sample) using the traditional smoking questions and the other half of respondents (one-quarter sample) using the revised smoking question ("Do you smoke every day, some days, or not at all?"). An unpublished analysis of the 1992 traditional smoking measure revealed that the crude percent of current smokers 18 years of age and over remained the same as 1991. The statistics for 1992 combine data collected using the traditional and the revised questions. In 1993-95 estimates of cigarette smoking prevalence were based on a half-sample. Smoking data were not collected in 1996. Starting in 1997 smoking data were collected in the sample adult questionnaire. For further information on survey methodology and sample sizes pertaining to the NHIS cigarette smoking data for data years 1965-92 and other sources of cigarette smoking data available from the National Center for Health Statistics, see Bibliographies and Data Sources, Smoking Data Guide.
