【摘要】 目的研究吸烟对职业噪声暴露人群的听力影响。方法以2009年来本院进行岗前体检、接触职业性噪声的作业人员作为研究对象。研究对象分为非吸烟人群(对照组)、吸烟人群(吸烟组);吸烟人群中,按吸烟数量多少(<10支/d;≥10支/d,<20支/d;≥20支/d)分为:低暴露组、中暴露组、高暴露组。分析研究对象2009、2012年职业健康检查结果,包括内科检查、纯音测听、血常规及生物化学检查等。结果纯音听力频率为0.5、1、2 k Hz时,对照组与吸烟组的听力受损率差异无统计学意义(P>0.05);3、4、6 k Hz频率时,对照组与吸烟组的听力受损率差异有统计学意义(P<0.05)。纯音听力频率为0.5、1、2、3 k Hz时,低、中、高暴露组听力受损率差异无统计学意义(P>0.05);4、6 k Hz频率时,低、中、高暴露组听力受损率差异有统计学意义(P<0.05)。结论吸烟为职业噪声暴露人群听力损失的危险因素,吸烟量的多少与听力损失呈正相关。更多还原

【Abstract】 Objective To study the relationship of smoking and hearing loss in occupational noise exposure workers. Methods Occupational noise exposure workers who had taken pre-service medical examination were considered as the research subjects. The research subjects were divided into non-smoking population( control group) and smoking population( smoking group). The smoking population were divided into low exposure group,moderate exposure group and high exposure group based on their smoking( < 10 cigarettes / day; ≥ 10 cigarettes / day,< 20 cigarettes / day; ≥ 20 cigarettes / day respectively). The occupational health examination results in 2009 and 2012 were analyzed,including medical examination,pure tone audiometry results,blood and biochemical tests. Results When pure tone audiometry frequency were 0. 5,1,2 k Hz,the hearing-impaired rate in control group and smoking group was not statistically significant( P > 0. 05); when pure tone audiometry frequency were 3,4,6 kHz,the hearing-impaired rate in control group and smoking group was statistically significant( P < 0. 05). When pure tone audiometry frequency were 0. 5,1,2,3 kHz,the hearing-impaired rate in low exposure group,moderate exposure group and high exposure group was not statistically significant( P > 0. 05); when pure tone audiometry frequency were 4,6 k Hz,the hearing-impaired rate in low exposure group,moderate exposure group and high exposure group was statistically significant( P < 0. 05). Conclusions Smoking is a risk factor of hearing loss of occupational noise exposure population,the amount of smoking was positively correlated with hearing loss.更多还原
