UNLABELLED
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.
本研究评估了美国中学生中当前经常吸烟的趋势。
方法
数据来自全国青年烟草调查（2000-2011 年）。当前经常吸烟定义为在过去 30 天内每天至少吸 20 支香烟。采用二项逻辑回归的线性系数评估趋势（p < 0.05）。
结果
所有学生中当前经常吸烟的比例从 2000 年（6.4%）降至 2011 年（3.6%）（线性趋势 p < 0.001）。按年龄、性别、种族/族裔、学校和年级水平观察到显著下降。
结论
需要持续努力进一步减少青少年使用所有烟草制品。
