目的分析2004-2005年中国宫颈癌死亡率、地区和人口分布特征以及近30年来的变化。方法采用多阶段分层整群抽样方法，对全国第三次全国死因回顾性抽样调查的15 8个抽样区(东部地区5 2个，中部地区49个，西部地区5 7个)进行人口学资料和宫颈癌死亡资料分析。样本总数为142 660 482人年，其中男性72 970 241人年，女性69 690 241人年。计算粗死亡率和年龄别死亡率。采用2000年人口普查资料，按5年间隔计算标化死亡率。并将死亡率资料与上一次全国死亡普查结果进行比较，分别为1970年的S和1990年的S。结果2004~2005年第三次死因回顾调查抽样区宫颈癌粗死亡率为2.86/10万(1995/69 690 241)，占2.86%(1995/69 667)，居女性所有癌症死因的第9位。农村和城市宫颈癌粗死亡率分别为2.88/10万(1326/46 091 419)和2.83/10万(669/23 598 822)，中国人口标化死亡率分别为2.01/10万和1.67/10万。1973-1975年和1990-1992年宫颈癌标化死亡率分别为11.10/10万和3.25/10万，分别占17.91%和4.86%，2004-2005年粗死亡率随年龄增长，从40岁开始明显上升，85岁达到高峰，为20.83/10万(82/393624)。35~44岁年龄组死亡率高于1990年S，中部、西部和东部地区粗死亡率分别为3.41/10万(827/24225738)、3.25/10万(636/19563647)和2.05/10万(532/2590856)，中国人口调整死亡率约为东部的两倍(中部为2.35/10万，西部为2.38/10万，东部为1.19/10万)。结论2004-2005年中国腹地宫颈癌死亡率农村高于城市，中西部高于东部。宫颈癌死亡呈年轻化趋势，与1973-1975年和1990-1992年相比，宫颈癌死亡率和女性肿瘤死亡构成比继续下降。
OBJECTIVE To analyze the cervical cancer mortality and distribution profiles by areas and population in 2004 - 2005 and the changes in the last 30 years. METHODS The demographic information and cervical cancer death data came from the Third National Retrospective Sampling Survey of Death Causes which including 158 sampling areas (including 61 cities and 97 villages; 52 in the east region, 49 in the middle region and 57 in the west region) covered 31 province-level regions in the interior of China by multiple stage stratified clustering sampling. The total number of the samples were 142 660 482 person years (72 970 241 person years in male and 69 690 241 person years in female). The crude and age-specific death rate was calculated. The standardized death rate was calculated by using 5 years interval from the census data of 2000. In addition, the mortality data was compared with the two previous national death surveys in 1970's and 1990's, respectively. RESULTS In the sampling region of the third retrospective death causes survey from 2004 to 2005, the crude death rate of cervical cancer was 2.86/100 000 (1995/69 690 241), which accounting for 2.86% (1995/69 667) and ranking 9th of all cancer death causes in female population. The crude death rates of cervical cancer were 2.88/100 000 (1326/46 091 419) and 2.83/100 000 (669/23 598 822) for rural areas and urban areas, respectively, the Chinese population adjusted death rates of rural and urban areas were 2.01/100 000 and 1.67/100 000, respectively. The standardized death rates of cervical cancer in 1973 - 1975 and 1990 - 1992 were 11.10/100 000 and 3.25/100 000, respectively, which accounting for 17.91% and 4.86%, respectively; in 2004 - 2005, the crude death rates increased by age, rose remarkably from the age of 40 and arrived the peak of 20.83/100 000 (82/393 624) at the age of 85. The mortality among 35 - 44 year-old group was higher than those in 1990's. The crude death rates of the middle, west and east areas were 3.41/100 000 (827/24 225 738), 3.25/100 000 (636/19 563 647) and 2.05/100 000 (532/25 900 856), respectively, the Chinese population adjusted death rates of the middle and west areas were about twice that of the east (2.35/100 000 in the middle, 2.38/100 000 in the west, and 1.19/100 000 in the east). CONCLUSION The mortality of cervical cancer was higher in rural areas than that in urban, as well as higher in the middle and west areas than that in east area in the interior of China in 2004 - 2005. Younger trend of cervical cancer death was observed; the mortality of cervical cancer and constituent ratio in the female tumor death continued to decline compared to those in 1973 - 1975 and 1990 - 1992.
