目的:了解2002-2009年厦门市城乡居民大肠癌死亡率分布特征和变化趋势。方法:对2002-2009年厦门市大肠癌死亡登记资料和人口数据进行统计分析,计算粗死亡率、标化率和年均增长率等指标,进行随机性检验和趋势性检验。结果:2002-2009年厦门市城乡居民大肠癌平均粗死亡率分别为8.57/10万和6.00/10万,标化率为5.16/10万和3.61/10万,明显低于全国肿瘤登记地区大肠癌死亡水平。城市居民死亡率高于农村,男性死亡率高于女性。城市居民和农村女性大肠癌死亡率呈明显上升趋势,女性死亡率上升幅度和速度高于男性。结论:厦门市城乡居民大肠癌死亡率呈上升趋势,女性人群更明显,应积极采取有效干预措施。

OBJECTIVE.. To investigate the distribution characteristics and mortality trend of colorectal cancer in urban and rural areas of Xiamen during the period of 2002--2009. METHODS.. Based on the data of demography and death collected through Xiamen＇s Disease Surveillance System （2002--2009）. The mortality rate, age-standardized rate and annual growth rate were used to describe the levels. Randomness test and trend test were performed as significance test. RESULTS： The crude mortality rate of colorectal cancer in urban and rural areas were 8.57/105 and 6.00/10s respectively, and the age-standardized rate by Chinese pop- ulation were 5. 16/105 and 3. 61/10% respectively from 2002 to 2009 in Xiamen, which were lower than the age-standardized rate by Chinese population in urban and rural areas of China. The mortality rate of colorectal cancer was higher in urban areas than in rural areas, and higher in male than in female. The mortality of colorectal cancer was significantly increased in these years, and the ascending speed of mortality in female was higher than that in male. CONCLUSIONS： The mortality rate of colorectal cancer in urban and rural areas of Xiamen have been significantly increased in these years, especially for the female. The effective measures should be carried out for colorectal cancer.
