STRATUM

Details

The interview sequence created a nested skip pattern for TOB5DAYS, USEDCIGS, DAYSCIGS, CIGSPERDAY, and LASTCIG. About 38% of the persons in this dataset skipped all five of these items because they were under 12 years old or because they did not participate in this portion of the NHANES examination for various reasons. The remaining 62% were asked the first question (TOB5DAYS): “During the past 5 days, did [participant] use any product containing nicotine...” If the answer was negative, the remaining items were skipped. The next question (USEDCIGS) pertained to cigarette use during the previous 5 days; if the response was negative, the remaining items were skipped.

NHANES uses a complex multistage sampling design, and design information should be taken into account when computing estimates and standard errors.
