中文摘要：

目的分析1990年与2013年中国人群胃癌的疾病负担及其变化情况。方法利用中国分省疾病负担研究结果，分析2013年中国胃癌疾病负担现状，比较1990年与2013年中国胃癌的发病、死亡、伤残调整寿命年（DALY）、过早死亡损失寿命年（YLL）和伤残损失寿命年（YLD）等，描述1990和2013年各省份胃癌发病、死亡及变化情况。结果2013年我国胃癌发病37．11万例、死亡31．78万例，标化发病率、死亡率、DALY率分别为26．84／10万、23．55／10万、464．47／10万，有随着年龄增加而逐渐增加的趋势。1990—2013年间男性胃癌标化发病率均高于女性（2．03～2．67倍），并均呈下降趋势。1990—2013年胃癌死亡数由28．21万增加到31．78万，增加13．15％。与1990年相比，2013年我国男女性胃癌的标化死亡率、DALY率、YLL率、YLD率均下降，且女性降幅均大于男性。2013年胃癌发病率和死亡率最高的前三个省份均为青海、安徽、甘肃，下降幅度最大的三个省份均为天津、上海、浙江；所有省份胃癌死亡率下降。结论2013年中国胃癌疾病负担仍处于较高水平；与1990年相比，2013年全国胃癌疾病负担下降，各省份胃癌死亡率均下降。但仍存在差异。

英文摘要：

Objective -To analyze the national and provincial disease burden on stomach cancer in the Chinese population, in 1990 and 2013. Methods Data related to province-specific burden of disease in China was used to analyze the standardized incidence and mortality of stomach cancer in 2013. Parameters as incidence, mortality, disability-adjusted life years （DALY）, years of life lost due to premature mortality （YLL） and years lived with disability （YLD） on stomach cancer in China in 1990 and 2013, were analyzed while the standardized incidence and mortality of stomach cancer in 1990 and 2013 and the changing patterns in each province were described. Results In 2013, there were 371 100 new cases of stomach cancer and 317 800 cases died from stomach cancer in China. Figures on the standardized incidence （26.84/100 000）, mortality rate （23.55/100 000） and DALY rate （464.47/100 000） all increased with age. Between 1990 and 2013, the standardized incidence rates in men were all higher than that in women （2.03-2.67 times） but both showed a decreasing trend. Under the reported figures, 317 800 people died from stomach cancer in 2013, with an increase of 13.15%. The number of deaths was 182 700, in 1990. From 1990 to 2013, the standardized mortality rate, DALY and DALY rate decreased in both genders,with more seen in women than in men. The top three provinces that having the highest stomach cancer standardized incidences and mortality in 2013 were Qinghai, Anhui, Gansu. The top three provinces with the most reduction of figures appeared in Tianjin, Shanghai and Zhejiang. Compared with those in 1990, the standardized mortality decreased in all the provinces, in 2013. Conclusions The disease burden of stomach cancer in China remained at high level in 2013. Compared with those in 1990, the disease burden of stomach cancer decreased in 2013. The standardized mortality of stomach cancer in all the provinces had decreased but the provincial differences still existed.
