Current Frequent Cigarette Smoking Among U.S. Middle and High School Students, 2000-2011.

This study assessed trends in current frequent smoking among United States middle and high school students. Methods: Data were obtained from the National Youth Tobacco Survey (2000-2011). Current frequent smoking was defined as smoking cigarettes on ≥20 days during the past 30 days. Trends were assessed using linear coefficients in a binary logistic regression ( p < 0.05). Results: Current frequent cigarette smoking among all students declined between 2000 (6.4%) and 2011 (3.6%) ( p < 0.001 for linear trend). Significant declines were observed by age, sex, race/ethnicity, school and grade level. Conclusion: Sustained efforts are needed to further reduce youth use of all tobacco products.
