Frequently Asked Questions
Tobacco use is a risk behavior that contributes to several major diseases, including lung cancer, heart disease, emphysema, and asthma, among others. Research on the correlates of smoking behavior can help policy makers devise better smoking prevention and cessation programs.
The first supplemental questionnaire on "smoking habits" appeared on the 1965 NHIS. Smoking prevalence and theories of behavioral change have advanced since then. As the questions changed, the variables have also changed. A smoking section was added to the NHIS core as part of a major questionnaire redesign for the 1997 data collection year. Since then, the core smoking variables have remained relatively consistent, although additions are made for periodic tobacco use supplements.
The Guide for Data Users provides links to the questionnaires, datasets, documentation and programming code for each NHIS dataset that contains tobacco-related information. Smoking status recodes are provided separately.
Supplementary questions on tobacco are added to the NHIS questionnaire periodically, for example, to monitor progress toward Healthy People goals and in Cancer Control Supplements. The questions may be changed if tobacco use behaviors change. For information on NHIS supplements, see: NHIS Supplements and Co-Sponsors, Datasets and Related Documentation 1969-1996 and Questionnaires and Related Documentation (1997-present).
No. The problem likely is due to using a 64-bit Microsoft operating system. NHIS Public Use data sets from 1970-2005 with the .exe file type are unable to be extracted on 64-bit computers running Microsoft operating systems. Data users are advised to rename the .exe files as .zip files and the data sets will extract correctly. This workaround is suggested for data years 1970-2005. For years 2006-2009, the .exe files do extract correctly. Beginning in 2010, NHIS data files are released as .zip files.
