Component Description

Smoking - Recent Tobacco Use (now named SMQRTU, previously named SMQMEC) provides details on past 5 days use of cigarettes, pipes, cigars and other forms of nicotine. The questions, asked of youths and adults, are of special interest for evaluating the Laboratory cotinine data (i.e., recent nicotine exposure).

Eligible Sample

The target sample, for the questions in this section, is persons age 12 years and older.

There were no proxy interviews. Participants 12-19 years old responded for themselves.

Interview Setting and Mode of Administration

These questions were asked at the mobile examination center (MEC) during the MEC Interview.. Adults 20 years and older were interviewed face -to -face, using computer assisted personal interviewing (CAPI). Youths 12-19 years responded for themselves using a 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

Edits were made to ensure the completeness, consistency, and analytic usefulness of the data.

Analytic Notes

SMQQUEX: Questionnaire source flag to distinguish between modes of interview (CAPI vs. ACASI).

Additional information on tobacco use is available in data files SMQ and SMQFAM. Note: Youth smoking history (12-19 years)_, formerly SMQMEC is now found in the data file SMQ.

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.
