摘要目的 分析2007-2015年陕西省成年人烟草流行现状及趋势变化.方法 利用2007、2010、2013和2015年全国慢性病及其危险因素监测数据,计算4次调查的吸烟率、吸烟量、戒烟率及二手烟暴露率,用趋势x2检验计算其变化趋势,以抽样权重及2010年第六次人口普查数据计算加权率,以敏感性分析加以验证.结果 2007年陕西省成年人吸烟率为38.26％,2013年降至30.95％,但2015年上升到34.11％(趋势性x2检验:Z=2.46,P=0.014);2007-2015年,陕西省吸烟者吸烟量从16.90支/d,上升到17.76支/d;成年人戒烟率从11.02％上升到16.95％(趋势性x2检验:Z=-4.18,P＜0.01);二手烟暴露率从2010年48.10％上升到2015年的63.88％(趋势性x2检验:Z=-10.60,P＜0.01).敏感性分析趋势不变.结论 2007-2015年,陕西省成年人吸烟率和吸烟量保持在比较高的水平且变化不大,虽然吸烟人群的戒烟率逐渐提高,但非吸烟人群中二手烟暴露率迅速增加.

abstractsObjective To understand the trends of smoking and passive smoking exposure in adults in Shaanxi province from 2007 to 2015.Methods Data was from China Chronic Disease and Risk Factor Surveillance in 2007,2010,2013 and 2015 to calculate the rates of smoking,smoking cessation and passive smoking exposure,as well as the amount of smoking of smokers indicated by each surveillance.Cochran-Armitage test was used to assess the trends across survey periods.The weighting rate was calculated by using sampling weight and data from the 6th national census in 2010.Sensitivity analysis was done to test the trends as well.Results The results of the surveillance indicated that the smoking rate in 2007 was 38.26％,highest in the results of four surveys,it decreased to 30.95％ in 2013 and then increased to 34.11％ in 2015 (Cochran-Armitage test:Z=2.46,P=0.014).The amount of smoking increased from 16.90 cigarettes per day in 2007 to 17.76 cigarettes per day in 2015.The overall rate of smoking cessation was 11.02％ in 2007 and 16.95％ in 2015 (Cochran-Armitage test:Z=-4.18,P＜0.01).We observed the passive smoking exposure rate was 48.10％ in 2010 and 63.88％ in 2015 (Cochran-Armitage test:Z=-10.60,P＜0.01).We found no difference in trends by sensitivity analysis.Conclusions The smoking rate and amount of cigarettes smoked in adults in Shaanxi remained stable and at a high level.The rate of smoking cessation increased gradually,while the passive smoking exposure rate increased rapidly.
