天津市交通警察吸烟状况及吸烟与呼出一氧化碳的相关性分析

Smoking Status of Tianjin Traffic Police and the Correlation Analysis Between Smoking and Exhaled Carbon Monoxide

目的探讨天津市交通警察吸烟情况及吸烟与呼出一氧化碳的相关性。方法于2015年5月~7月采取整群随机抽样的方式,抽取2315名天津市交通警察进行问卷调查,分析调查对象的人口学特征、每日吸烟量与烟龄吸烟者分布、调查对象呼出CO浓度与吸烟相关性及影响调查对象呼出CO浓度的因素。结果共发出问卷2315份,收回有效问卷2183份,有效回收率为94.30%;从不吸烟者40.50%,吸烟者59.50%,男性交警吸烟率67.20%,女性交警吸烟率0.79%,戒烟并成功者7.50%;不同性别、年龄、每日吸烟量、烟龄人群CO浓度比较,差异有统计学意义(P<0.05);多因素Logistic回归分析显示,轻度、中度与重度增加组的烟龄、每日吸烟量以及轻度增加组中20~49岁、中度增加组中20~29岁、重度增加组中30~49岁是呼出CO浓度的影响因素(P<0.05)。结论天津市交通警察吸烟人数仍占有较高比例,戒烟人数较少,每日吸烟量、烟龄为呼出CO浓度增高的危险因素。

Objective To explore the smoking status of Tianjin traffic police and the correlation between smoking and exhaled carbon monoxide.Methods A cluster random sampling method was adopted from May to July 2015,and 2,315 Tianjin traffic police officers were selected to conduct a questionnaire survey.The demographic characteristics of the survey subjects,the distribution of daily smoking and smoking age smokers,the correlation between the survey subjects'exhaled CO concentration and smoking,and the factors affecting the survey subjects'exhaled CO concentration were analyzed.Results A total of 2,315 questionnaires were sent out,and 2183 valid questionnaires were retrieved.The effective recovery rate was 94.30%;never smokers 40.50%,smokers 59.50%,male traffic police smoking rate 67.20%,female traffic police smoking rate 0.79%,those who quit smoking successfully 7.50%;Comparison of CO concentration among people of different gender,age,daily smoking amount and smoking age,the difference was statistically significant(P<0.05);Multivariate Logistic regression analysis showed that the smoking age,daily smoking amount in the mild,moderate,and severely increased groups,and 20 to 49 years old in the mildly increased group,and 20 to 29 years old in the moderately increased group.The 30 to 49 years old in the severely increased group was the influencing factor of the exhaled CO concentration(P<0.05).Conclusion The number of smokers in Tianjin traffic police still accounts for a relatively high proportion,and the number of people who quit smoking is small.Daily smoking and smoking age are risk factors for increased exhaled CO concentration.
