1981—2005年昆山市居民肺癌死亡率趋势

Analysis of Secular Trend of Lung Cancer Mortality Rate in Kunshan City, 1981—2005

目的分析1981—2005年昆山市居民肺癌死亡率变化趋势。方法采用昆山市1981—2005年全死因登记报告资料,计算肺癌粗死亡率、中国人口标化率及世界人口调整率、35～64岁截缩调整率、0～74岁累积死亡率、变化百分比(PC)及年度变化百分比(APC),并对不同年龄、不同时期居民的死亡率进行比较和分析。结果肺癌年平均粗死亡率为27.88/10万,其中男性为43.19/10万,女性为12.56/10万,死亡率的性别比为3.44∶1。世界人口调整率为22.52/10万,其中男性为37.28/10万,女性为9.67/10万。35～64岁肺癌截缩调整率为31.54/10万,0～74岁累积死亡率为0.10%。粗死亡率的PC为144.56%,APC为4.08%;世界人口调整率的PC为23.57%,APC为1.01%。结论1981—2005年昆山市肺癌死亡率较高,且呈上升趋势。

Objective To evaluate the secular trend of lung cancer mortality rate during 1981 to 2005 in Kunshan City. Methods The population-based registration data collected during the period of 1981-2005 were used to calculate the crude rate （CR）, world age-standardized rate （WASR）, five-year age-specific rate, truncated rate of those aged 35-64, cumulative rates of those aged 0-74, percent change （PC）, and annual percent change （APC）. The mortality rates by age, period/age, and cohort/age were analyzed and compared. Results The CR was 27.88 per 100 000 on average, and was 43.19 per 100 000 for males and 12.56 per 100 000 for females, with a sex ratio of 3.43： 1. The WASR was 22.52 per 100 000 on average, and 37.28 per 100 000 for males and 9.67 per 100 000 for the females. The truncated rate and cumulative rate of those aged 0-74 were 31.54 per 100 000 and 0.10% respectively. The PC and the APC were 144.56% and 4.08% for the crude mortality rate, and 23.57% and 1.01% for the age-standardized rate. Birth cohort and period data analysis showed rising of lung cancer of age-specific rate. Conclusion The mortality data demonstrated a rising trend in general in the period of 1981-2005 in Kunshan.
