目的了解浙江省宁波市妇女子宫颈癌死亡特征及变化趋势。方法参照Arbyn等介绍的方法对宁波市2002-2011年上报的子宫颈癌死亡率进行校正,计算子宫颈癌粗死亡率。采用对数线性回归方法和加权χ2方法分析子宫颈癌死亡率的时间趋势和城乡妇女子宫颈癌死亡率的差异。结果 2002-2011年宁波市妇女子宫颈癌校正前粗死亡率为2.78/10万,中标率为2.18/10万,世标率为2.26/10万,校正后粗死亡率为5.19/10万,中标率为4.07/10万,世标率为4.21/10万。校正前后子宫颈癌死亡率均随年龄增长而升高(校正前χ2趋势=818.261,P=0.000;校正后χ2趋势=1 563.041,P=0.000)。2002-2011年宁波市妇女校正后子宫颈癌粗死亡率波动在4.41/10万～5.99/10万之间,差异无统计学意义(EAPC:0.60%,95%CI:-0.30%,1.51%);中标率波动在3.52/10万～4.60/10万之间,有下降趋势(EAPC:-2.08%,95%CI:-3.63%,-0.40%);世标率波动在3.51/10万～4.85/10万之间,有下降趋势(EAPC:-1.09%,95%CI:-1.88%,-0.20%)。农村妇女子宫颈癌死亡率高于城市妇女子宫颈癌死亡率(加权χ2=34.892,P=0.000)。结论随着时间的推移,宁波市妇女子宫颈癌呈下降趋势,但仍维持在较高水平,农村妇女子宫颈癌死亡率高于城市妇女子宫颈癌死亡率。
Objective To investigate the characteristics of cervical cancer death and its changing trend in Ningbo City, Zhejiang Province. Methods According to the method introduced by Arbyn et al, the mortality rate of cervical cancer reported by Ningbo from 2002 to 2011 was corrected to calculate the crude mortality rate of cervical cancer. Logistic regression method and weighted χ2 method were used to analyze the time trend of cervical cancer mortality and the difference of cervical cancer mortality rate between urban and rural women. Results In 2002-2011, the pre-correction crude mortality rate of cervical cancer in Ningbo was 2.78 / 100 000, the successful rate was 2.18 / 100 000, the world standard rate was 2.26 / 100 000, the corrected crude mortality rate was 5.19 / 100 000, The winning rate was 4.07 / 100,000, the world standard rate was 4.21 / 100,000. Cervical cancer mortality before and after correction increased with age (trend χ2 before correction = 818.261, P = 0.000; trend χ2 after correction = 1 563.041, P = 0.000). The crude mortality rate of cervical cancer after correction in Ningbo women was between 4.41 / 100 000 and 5.99 / 100 000 between 2002 and 2011, with no significant difference (EAPC: 0.60%, 95% CI: -0.30%, 1.51% ); The winning rate fluctuated between 3.52 / 100000 ~ 4.60 / 100,000 with a downward trend (EAPC: -2.08%, 95% CI: -3.63%, -0.40%); the world standard rate fluctuated at 3.51 / ~ 4.85 / 100 000, there is a downward trend (EAPC: -1.09%, 95% CI: -1.88%, -0.20%). Cervical cancer mortality in rural women was higher than in urban women (weighted χ2 = 34.892, P = 0.000). Conclusions With the passage of time, cervical cancer in Ningbo women is on the decline, but still maintained at a high level. The cervical cancer death rate of rural women is higher than that of urban women.
