Objective: To analyze the changes in tobacco use and exposure in primary school students in Shandong province in 2012 and 2019. Methods: A multi-stage stratified cluster random sampling method was used in the survey. In 2012 and 2019, 5 861 and 4 021 students from 3 different cities of Shandong province were selected as the study population. The questionnaire was filled anonymously by the subjects. χ2 test was conducted to compare the difference of groups. Results: In 2012 and 2019, the rate of attempting smoking among pupils under this study in Shandong province were 6.0％and 6.3%, respectively, while the current smoking rate were 1.2％and 2.3%, respectively. The sex ratio of male and female students attempting to smoke was 2.56∶1 in 2012 and 1.31∶1 in 2019. The sex ratio of current smoking rate was 2.43∶1 and 2.00∶1, respectively in 2012 and in 2019. The rate of tobacco exposure in the public places was 50.5％and 41.4%, respectively. The rate of tobacco exposure in family was 49.7% and 46.4%, respectively. Two rates of tobacco exposure decreased, but the reduction in family (3.3%) was far less than that in public places (9.1%). In 2019, the rate of tobacco exposure in family was higher than that in public places. Conclusions: The tobacco exposure rate declined in senior pupils in Shandong province. However, the situation is still grim for the current smoking rate, growth trend of girls tobacco use, and tobacco exposure in family.
目的： 比较山东省高年级小学生2012年与2019年烟草使用和暴露情况。 方法： 采用分层整群随机抽样的方法，在山东省东、中、西部各抽取1个市进行监测，每个市随机抽取城市和农村小学各2 所，由研究对象匿名填写调查问卷，2012年和2019年分别调查3~6年级学生5 861人和4 021人。采用χ2检验对不同组别的情况进行比较。 结果： 山东省高年级小学生2012年和2019年的尝试吸烟率分别为6.0%和6.3%，现在吸烟率分别为1.2%和2.3%。尝试吸烟率2012年的男女生性别比为2.56∶1，2019年缩小为1.31∶1，现在吸烟率2012年的男女生性别比为2.43∶1，2019年缩小为2.00∶1。公共场所烟草暴露率分别为50.5%和41.4%，家庭烟草暴露率分别为49.7%和46.4%。两个场所的烟草暴露率均有所降低，家庭烟草暴露的降低幅度（3.3%）小于公共场所的降低幅度（9.1%），且2019年高年级小学生家庭烟草暴露率已高于公共场所。 结论： 山东省高年级小学生的烟草使用情况不容忽视，特别是现在吸烟率和女生的烟草使用增长趋势较为严峻。公共场所和家庭的烟草暴露情况虽有所改善，但家庭烟草暴露情况仍需重点、持续地进行关注和干预。.
