【Abstract】 Objective To investigate the risk factors of lung cancer in Rongqi area Shunde,Foshan City. Methods A case-control study was carried out.Both 120 cases with lung cancer and 120 cases without lung cancer(more exactly no tumor before)were required to answer the standard questionnaire.All OR values and P values of risk factors were obtained statistically,based on the descriptive analysis of the survey. Results Smoking( OR =5.67)?heavy smoking(smoking index≥400 piece.year)( OR =11.8)?living in air-polluted area( OR =3.01)?indoor pollution( OR =2.94)?long-term contact with oil mist( OR =2.2)?long-term indoor burning joss sticks( OR =3.45)were significantly related to local lung cancer,while passive smoking( OR =0.91)?adequate intake of fresh vegetable and fruit( OR =0.81)with no significant relation.Regular exercises( OR =0.57)had a significantly negative relation to local lung cancer. Conclusions The risk factors of lung cancer in Rongqi district mainly include smoking,pollution,indoor pollution,long-term depression,positive chronic pulmonary diseases,family history of cancer.Physical exercise is one of the protective factors,but the role of passive smoking and dietary needs further study.更多还原
