Notice and Correction of 2004 NYTS Data Errors
Dataset
An error was made in the computation of the analytic weights for the
original 2004 NYTS dataset. Subsequently, analysis using these data will lead
to miscalculation of both estimates and standard errors.
The 2004 NYTS dataset has since been corrected. Data users
who downloaded the NYTS
dataset from the Office on Smoking and Health’s Web site prior to November 26, 2005, should destroy any copies kept on file. Any analysis
conducted using the improperly weighted original dataset should be re-run
using the corrected dataset.
MMWR—Tobacco Use, Access, and Exposure to Tobacco in Media Among
Middle and High School Students—United States, 2004
April 1, 2005 / Vol. 54 / No. 12
Calculations for the MMWR article “Tobacco
Use, Access, and Exposure to Tobacco in Media Among Middle and High School
Students—United States, 2004 were conducted using the original, improperly weighted NYTS dataset. Subsequently, both estimates and standard errors were affected.
Analysis has been re-run and shows the following:
Among Asian middle school students, use of any tobacco (5.1%), bidis (1.1%), and kreteks (1.5%) did not significantly decrease from 2002–2004
as previously reported (Text and Table 1) in the original article. Among
Hispanic high school students, use of bidis (4.8%) significantly increased
from 2002–2004 in addition to the increase in cigar use previously reported
(Table 2) in the original article. Lastly, among female and black non-Hispanic
high school students, those who reported they were not refused the purchase
of cigarettes (70.8% and 70.9%, respectively) did not significantly change
from 2002–2004 as previously reported (Text and Table 3) in the original
article.
These corrected data yield the same key finding as was previously
reported: the
lack of significant decreases in the use of almost all tobacco products
among U.S. middle and high school students from 2002 to 2004 underscores
the need to fully implement evidence-based strategies that are effective
in preventing youth tobacco use. Please see below for further information.
