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.

The mean is one such measure, calculated by totaling all values in a dataset and dividing by the number of values. For instance, the mean blood pressure reading (120, 130, 140, 150) would be 135. However, the mean can be affected by extreme values or outliers.
The median, another measure,...
