Smoking epidemiology among primary and middle school students in Beijing during 2005-2015 / 中国学校卫生

ABSTRACT

Objective@#To understand the changes of smoking behavior among primary and middle school students in Beijing during 2005-2015.@*Methods@#The primary and middle schools in Beijing were classified and then taken as a sampling frame. Twophase stratified random cluster sampling was conducted with school as primary sampling unit (PSU) and class as the minimum sampling unit, respectively. Beijing Schoolbased Smoking Monitoring Questionnaire was surveyed in 2005 and 2005, 2010, 2011, 2013 and 2015 anonymously.@*Results@#In 2015, the smoking rate among primary and middle school students in Beijing was 9.41%. Among them, for primary, junior, high school and vocational high school students, the rates were 7.05%, 7.06%, 12.41% and 34.11%, respectively. The smoking rates were now 3.26%, with 1.99%, 1.80%, 3.48% and 20.22%, respectively, among primary, middle and high school and vocational high school students. male, vocational school students were more likely to report smoking across six waves of surveillance. Results from the surveillance in 2015 showed a decreasing trend in ever smoking rate and current smoking rate compared with previous survey. About half of the current student smokers were reported to take 1 cigarette/day, and about 10% smokers were reported to take 10 cigarettes/day. Students were most likely to smoke at home(24.02%), followed by smoking at schools(12.74%). The percentage of buying cigarettes by themselves was increased from 17.10% in 2008 to 66.09% in 2015.@*Conclusion@#From 2005 to 2015, both ever smoking and current smoking rate among middle school students in Beijing decreased in general, however smoking among vocational high school students warrants further attention.
