Component Description

This Smoking data file provides data on cigarette use;history of use, age at initiation, current use, past 30-day prevalence, amount, cigarette brand, and other related details for adults and youths.

Questions on history of cigar, pipe and other forms of tobacco found on earlier releases of NHANES are no longer included in the survey; however current use of these products is part of the SMQMEC (1999-2004) and SMQRTU (2005-2006) data files.

Eligible Sample

All survey participants 12 years and older were eligible.

Interview Setting and Mode of Administration

For adults, 20+ years, these questions were asked before the physical examination, in the home, using the Computer-Assisted Personal Interviewing-CAPI (interviewer administered) system.

For youths, these questions were asked during the physical examination, at the Mobile Examination Center (MEC), in the MEC Interview Room. Youths 12-19 years responded for themselves using the audio computer -assisted self -interview (ACASI) technique, in English or Spanish only.

Quality Assurance & Quality Control

The CAPI and ACASI systems are programmed with built-in consistency checks to reduce data entry errors. CAPI also uses online help screens to assist interviewers in defining key terms used in the questionnaire.

Data Processing and Editing

The data were reviewed and edited for completeness, consistency, and illogical values.

Analytic Notes

Data on initiation of smoking, and history of cigarette use for youths 12-19 years that were asked in the ACASI interview and were formerly part of the SMQMEC data files (1999-2004) are now part of this data fileThe few questions that were identical for both youth and adults are now combined for the full age range of 12 years and older. Compared with questions asked of adults, the Overall, questions for youths were more limited in scope. Refer to the codebook for variable names and eligible sample by question.

Since the SMQ questions for respondents 20 years and older were asked in the home interview, the interview sample weights may be used in their analysis. However, if the data are used in combination with data from the MEC, the MEC sample weights should be used. Analysis of the SMQ questions for 12 to 19 year olds should use the MEC sample weights as the questions were asked in the MEC.

Data from questions on recent tobacco use collected during the MEC interview is currently found in the data file SMQRTU. In addition, data from questions about exposure to tobacco in the home is available in SMQFAM.

Please refer to the Analytic Guidelines for further details on the use of sample weights and other analytic issues. The Analytic Guidelines are available on the NHANES website.
