上海市职校学生吸烟倾向的环境感知系统因素分析

Analysis on smoking intention by perceived environmental system among vocational school students in Shanghai

目的探讨环境感知系统因素对上海市职业学校学生吸烟倾向的影响,为职校学生控烟干预提供依据。方法利用横断面调查,采用分层整群随机抽样,对上海市6所职校学生进行问卷调查。采用多因素Logistic回归方法分析环境感知系统因素对职校学生吸烟倾向的影响。结果获得有效问卷3931份,在被调查者中有吸烟倾向的占比31.5%,男生(40.9%)高于女生(18.5%)(P<0.01),年龄在16岁及以上的职校学生吸烟倾向(33.14%)高于未满16岁的(26.26%)(P<0.01)。环境感知系统中的6种因素对职校学生未来吸烟倾向有影响,低吸烟危害认知水平组相对于高吸烟危害认知水平组未来吸烟倾向更大(ORm=1.30,95%CI:1.10~1.55)、高家庭烟草接触暴露水平组相对于低家庭烟草接触暴露水平组未来吸烟倾向更大(ORm=1.54,95%CI:1.23~1.91)、高同伴烟草暴露水平组相对于低同伴烟草暴露水平组未来吸烟倾向更大(ORm=5.46,95%CI:4.09-7.29)、高二手烟暴露水平组相对于低二手烟暴露水平组未来吸烟倾向更大(ORm=1.28,95%CI:1.07~1.53)、对烟草使用的外在印象好组相对于对烟草使用的外在印象差组未来吸烟倾向更大(ORm=1.39,95%CI:1.17~1.66)、对烟草使用的内在印象好组相对于对烟草使用的内在印象差组未来吸烟倾向更大(ORm=1.34,95%CI:1.12-1.59)。结论环境感知系统与职业学校学生吸烟倾向密切相关,可通过改善环境感知系统降低职业学校学生吸烟倾向。

Objective To analyze the influence of perceived environmental system factors on smoking intention and provide the theoretical basis for tobacco control among vocational school students in Shanghai.Methods A cross-sectional study was conducted among 6 vocational schools in Shanghai by stratified cluster sampling.The multiple Logistic regression method was used to assess the impact of perceived environment system factors on smoking intention.Results 3931 valid questionnaires were obtained.The rate of tobacco use intention in vocational school students was 31.5%.The rate of smoking intention of boys was 40.9%,which was significantly higher than that of girls(18.5%,P<0.01).The smoking tendency of vocational school students aged 16 years and above(33.14%)was higher than that of those under 16 years old(26.26%,P<0.01).The smoking intention was closely related to 6 perceived environmental system factors.Compared with the group with high level of tobacco hazard cognition,the low level group had a higher tendency to smoke in the future(ORm=1.30,95%CI:1.10-1.55).The group with high level of family tobacco exposure,high level of peer tobacco exposure,high level of second-hand smoke exposure,with good external impression of tobacco use,with good external impression of tobacco use was more likely to smoke in the future(ORm=1.54,95%CI:1.23-1.91;ORm=5.46,95%CI:4.09-7.29;ORm=1.28,95%CI:1.07-1.53;ORm=1.39,95%CI:1.17-1.66;ORm=1.34,95%CI:1.12-1.59,respectively).Conclusion The perceived environmental system factors can affect smoking intention of vocational school students.The intention to smoke can be declined by improving the perceived environmental system.
