行为生活方式对恶性肿瘤发病影响的综合分析

目的：通过综合分析主要生活行为危险因素的变化趋势及其对恶性肿瘤影响的严重程度，预测其暴露水平对恶性肿瘤发生发展的影响，为制定恶性肿瘤防治策略和规划提供科学依据。方法：采用综合分析方法，估计恶性肿瘤主要行为危险因素的人群归因危险度百分比及其对恶性肿瘤发生的影响。结果：通过对吸烟、饮酒和水果蔬菜摄入的人群暴露率的预测及根据暴露率的变化，估计人群归因危险度百分比的变化趋势，以及估计5种恶性肿瘤发病率的变化结果，可以看出，随着以上危险因素暴露率的降低，肺癌、胃癌、食管癌、肝癌和大肠癌的发病率均随之呈不同程度的下降。结论：在预防恶性肿瘤的工作中，针对恶性肿瘤的危险因素，加强一级预防，减少人群的不良生活习惯，改善饮食结构，将产生明显的社会效益，具有很大的公共卫生潜能。

Integrated analysis of effects of life style on incidence of malignant tumor

Objective To provide evidence for decision-making on cancer prevention through studying the trend of main life-style risk factors and their impact on cancer in Chinese people.Methods To estimate the population attributable risk percent(PARP) of behavior risk factors and the effect on the cancer incidence.Results Accompanying the decreasing of these risk factors such as smoking,drinking,the intake of fruit and vegetable,the incidence of the cancers(including the lung,stomach,esophageal,liver and rectum and colon cancer)will decrease to some extent.Conclusion It would produce significant social effect to strengthen the primary prevention in the cancer prevention,which is much potential for prevention of cancer in China.
