The Recent Tobacco use (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.
The target sample is persons ages 12 years and older. 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 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. Because this data set is the concatenation of data collected using two separate modes, a special variable, SMAQUEX was created, as a flag, to designate each interview mode.
Additional questionnaire data on tobacco use is available in data files SMQ and SMQFAM. For laboratory-related data, see COTNAL.
The NHANES full sample 2-Year MEC Exam Weights (WTMEC2YR) should be used to analyze the 2009-2010 SMQRTU.
