RESUMO
OBJECTIVE@#To study the incentives of laryngeal cancer in Heilongjiang province.@*METHOD@#A 1:One matched case control study was used to study the risk factors of laryngeal cancer in Heilongjiang province, distributing all tested staff by the same gender, age, urban and rural. Logistic regression models were used to analysis the relationship.@*RESULT@#In single Logistic regression models, such habit as high levels of education, frequently consumption of sauerkraut, BBQ food, processed meats, the less physical activity, a relatively short time, smoking, irascible, and other factors would increase the risk of suffering from laryngeal cancer. But regular consumption of fresh vegetables, coarse grains, eggs, milk, and regular physical activity would reduce the risk of suffering from laryngeal cancer. The odds ratios (OR) were calculated using multiple Logistic regression models, ORs for the highest versus the lowest quintile of intake were 15.502 0 for high levels of education. 8.012 0 for smoking frequently. 7. 2680 for eating sauerkraut. 2.904 0 for eating BBQ food. 0.408 0 for exercise in protective factors.@*CONCLUSION@#Potential risk factors for laryngeal cancer were eating sauerkraut. BBQ food and smoking frequently, but proper exercise may reduce the risk of laryngeal cancer.
