背景与目的:随着我国经济的快速发展,人们的生活水平大幅提高,膳食模式也发生了变化,这可能会增加肠癌发生的危险。本研究分析1970年—2005年期间山东省肠癌患者死亡率的变化趋势,为肠癌的防治提供理论依据。方法:利用1970年—2005年期间的4次全死因调查资料,计算肠癌患者死亡率和世界人口标化死亡率,并利用Joinpoint软件分析肠癌患者死亡率的升降速率及其变化特征。结果:山东省肠癌患者的死亡率由1970年—1974年期间的3.62(标化率4.33)上升到2005年的6.96(标化率5.77),按标化率计算上升了33.26%;其中男性上升了50.75%,女性上升了6.97%。1970年—1974年期间和2005年男女性别比分别为1.1∶1.0和1.4∶1.0。回归分析显示,肠癌死亡率在1970年—1992年期间呈上升趋势,年均增长速率为1.05%(P=0.042);从1922年开始呈稳定缓慢小幅上升趋势;肠癌死亡率随着年龄的增长而升高,从35岁开始,各年龄组患者的肠癌死亡率加速上升;男性高于女性,城市高于农村。结论:山东省肠癌死亡率呈上升趋势,应加强预防肠癌发生的知识宣教。
Background and Objective: With the rapid economic development in our country, people’s living standards have risen dramatically and dietary patterns have also changed. This may increase the risk of developing colorectal cancer. This study analyzed the trend of mortality of patients with colorectal cancer in Shandong Province from 1970 to 2005, and provided a theoretical basis for the prevention and treatment of colorectal cancer. Methods: Four all-cause investigation data were collected from 1970 to 2005 to calculate the mortality rate of the patients with colorectal cancer and the world’s population standardized mortality rate. The Jointer software was used to analyze the rate of death and rate of death in patients with colorectal cancer. Results: The mortality rate of colorectal cancer patients in Shandong Province increased from 3.62 (standardized rate 4.33) in 1970-1974 to 6.96 (standardized rate 5.77) in 2005, and increased by 33.26% at the standardization rate. Among them, male Rose by 50.75% and women increased by 6.97%. The sex ratio between men and women for the years 1970-1974 and 2005 was 1.1: 1.0 and 1.4: 1.0, respectively. Regression analysis showed that the mortality rate of colorectal cancer increased from 1970 to 1992, with an average annual growth rate of 1.05% (P = 0.042); from 1922, it showed a steady and slight upward trend; the mortality of colorectal cancer with age Increased from the age of 35, and the mortality of colorectal cancer in all age groups accelerated at an earlier age of 35; the male was higher than the female and the urban was higher than the rural. Conclusion: The mortality rate of colorectal cancer in Shandong Province is on the rise. Knowledge and education on the prevention of colorectal cancer should be strengthened.
