Exposure to pro-tobacco messages was a significant predictor for current smoking, whereas exposure to anti-tobacco messages and exposure to information about health consequences of tobacco use were not significant predictors for current smoking in IYTS 2000 and 2004 in the adjusted logistic models.
Perceived benefit of smoking, measured by summating 5 relevant items in IYTS 2004, was also significantly associated with current smoking.
As was observed in the current smoking, gender was not significant but grade and race/ethnicity were significant in predicting students' established smoking status in IYTS 2000 and 2004 (Tables 5 and 6).
As was observed in current smoking, exposure to pro-tobacco messages was a significant predictor for established smoking, whereas exposure to anti-tobacco messages and information about health consequences were not significant predictors in IYTS 2000 and 2004 adjusted logistic models.
The findings of this study support the inclusion of items in IYTS 2004 that measured perceived peer acceptance to smoking as they were significantly associated with OFS.
