NHsmoking {lcca} | R Documentation |
This dataset was derived from the 2005–2006 National Health and Nutrition Examination Survey (NHANES) and pertains to self-reported smoking behavior of survey participants age 12 years and older.
NHsmoking
a data frame with 10,348 rows and 9 variables:
WEIGHT
respondent's survey weight
CLUSTER
sampling cluster identifier,
nested within STRATUM
STRATUM
sampling stratum identifier
AGEYRS
respondent's age in years
TOB5DAYS
“During the past 5 days, did [participant] use any product containing nicotine...” (1=not asked or refused, 2=no, 3=yes)
USEDCIGS
Used cigarettes during last 5 days? (1=skipped, 2=none/don't know/refused, 3=yes)
DAYSCIGS
Smoked cigarettes on how many of last 5 days? (1=skipped, 2=1, 3=2, 4=3, 5=4, 6=5)
CIGSPERDAY
How many cigarettes smoked each day? (1=skipped, 2=1-5 per day, 3=6-10 per day, 4=11+ per day, 5=don't know/refused)
LASTCIG
When last cigarette was smoked (1=skipped, 2=3-5 days ago, 3=yesterday, 4=today)
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.
