Component Description

The Recent Tobacco Use (variable name prefix SMQRTU) data set provides details on use of cigarettes, pipes, cigars and other forms of tobacco as well as nicotine replacement therapies (e.g., nicotine patches), in the past 5 days. Prior to 2005-2006, these data were included in the data file SMQMEC.

Eligible Sample

All participants ages 12 years and older are eligible. For participants 12-19, there were no proxy interviews.

Interview Setting and Mode of Administration

These questions were asked at the Mobile Examination Center (MEC) during the MEC Interview. For Adults 20 years and older, questions were asked by trained interviewers using the Computer-Assisted Personal Interviewing (CAPI) system. For Youths 12-19 years, questions were self-administered using the Audio Computer-Assisted Self-Interviewing (ACASI) system, in English and 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

Edits were made to ensure completeness, consistency and analytic usefulness of the data. A special variable, SMAQUEX was created as a flag to designate each interview mode.

Analytic Notes

Additional questionnaires on cigarette smoking are located in the SMQ and SMQFAM data files. Two biologic indicators of tobacco exposure serum cotinine (metabolite of nicotine) and urinary NNAL measurements are available in the COTNAL laboratory data file.

The NHANES full sample 2-Year MEC Exam Weights (WTMEC2YR) should be used to analyze the 2011-2012 SMQRTU variables in conjunction with the laboratory measurements on tobacco exposure or other examination measurements.

Please refer to the NHANES Analytic Guidelines and the on-line NHANES Tutorial for further details on the use of sample weights and other analytic issues.
