Abstract: Objective To know about the distribution and trend of current smoking among middle and high school students in Haidian district,in order to provide reference for making effective interventions.Methods Using multi-stage cluster random sampling method,a total of 20 938 students had been surveyed with standard questionnaires,and the sample was 4 259,4 016,3 975,3 869 and 4 819 students in 2008,2010,2012,2014 and 2016,respectively. And 12 school doctors and one health inspector were interviewed about smoking policies of the schools,the interviewers observed and recorded the on-site information about cigarette stores and advertisements around the campus. Results The current smoking rate for middle and high schoolers in Haidian was 7.14%,with 3.11% for middle schoolers and 9.99% for high schoolers. The variance coefficients for middle schools and high schools were 82.18% and 106.56%,respectively.Vocational schools had higher rate of the smoking than common high schools(χ²=724.955,P<0.001). Common high schools and middle schools held greater smoking rates than corresponding middle schools and high schools(χ²=27.738,61.812,P<0.001). Among students in higher grade,the smoking rate was much higher (χ²=301.324,P<0.001). Male students were more likely to smoke than female students (χ²=415.147,P=0.001). Current smoking prevalence has declined in any of the three school types for male or female students. Current smoking rate for middle schoolers had decreased from 5.24% in 2008 to 1.05% in 2016(χ²=53.071,P<0.001),while it was from 13.53% to 5.74% for high schoolers (χ²=79.157,P<0.001). In the wake of the enforcement of No Smoking Campus policy in 2010,current smoking rate began to drop. But in 2012,the rate rebounded. Likewise,after the implementation of Controlling Smoking Act in 2015,the smoking rate fell again. Conclusions The smoking rate for middle and high schoolers in Haidian district has been decreasing. No Smoking Campus policy implemented in 2010 and Controlling Smoking Act in Beijing approved in 2014 might have contributed to the decrease
