目的 探讨顺德容奇地区肺癌的危险因素。方法 采用病例对照研究方法 ,对 12 0例肺癌患者及 12 0名非肺癌者 (无肿瘤史 )采用统一的标准问卷调查 ,对数据资料进行统计学分析 ,计算各危险因素的OR值及P值。结果 吸烟 (OR =5 67) (尤其是吸烟指数≥ 40 0支·年 ,OR =11 8) ;住在大气污染区 (OR =3 0 1) ,室内污染严重 (OR =2 94) ,长期接触油烟 (OR =2 2 ) ,室内长期烧香 (OR =3 45 ) ,与容奇地区的肺癌显著相关 ;被动吸烟 (OR =0 91) ,经常吃蔬菜水果 (OR =0 81) ,与肺癌无显著相关 ,经常体育锻炼 (OR =0 5 7) ,与肺癌负相关有显著性。结论 吸烟、大气污染、室内污染、长期精神压抑、既往呼吸疾病史、家族肿瘤史是容奇地区肺癌主要危险因素 ,体育锻炼是保护因素 ,被动吸烟、饮食作用有待进一步研究。
Objective To investigate the risk factors of lung cancer in Shunde Rongqi area. Methods A case-control study was conducted. A standardized questionnaire was used to investigate the data of 120 lung cancer patients and 120 non-lung cancer patients (no tumor history), and the data were analyzed statistically. The OR and P values of each risk factor . (OR = 5 67) (especially, the smoking index ≥ 40 0, OR = 11 8). In the air pollution area (OR = 301), the indoor pollution was serious (OR = 2 94) Long-term indoor burn (OR = 3 45) was associated with lung cancer in Rongqi area, passive smoking (OR = 0 2), long-term indoor burning of incense No significant correlation, regular physical exercise (OR = 0 57), and lung cancer negative correlation was significant. Conclusion Smoking, air pollution, indoor pollution, long-term depression, history of previous respiratory diseases and family history of cancer are the major risk factors for lung cancer in Rongqi. Physical exercise is a protective factor, passive smoking and dietary effects need further study.
