To analyze the long-term trend of mortality and years of life lost (YLL) of gastric cancer in Tianjin from 1999 to 2015. From January 1, 1999 to December 31, 2015, the data of gastric cancer deaths was collected from the Tianjin death surveillance system. The inclusion criteria of death due to gastric cancer were coded by using 151 in the 9(th) edition of the international classification of diseases (ICD) (1999-2002) and C16 in the 10(th) edition of ICD (2003-2015). The crude and age-standardized mortality rate (ASR) of gastric cancer was calculated according to Segi's world standard population. YLL was calculated according to the standard method of the disease burden of WHO. The Joinpoint regression was used to calculate the average annual percentage change (AAPC) to indicate the trend of mortality and YLL of gastric cancer. From 1999 to 2015, there were 20 000 deaths of gastric cancer in Tianjin. The proportion of gastric cancer death in the population aged 0-44 years old, 45-64 years old, and 65 years old and above was 4.9%, 30.4%, and 64.8%, respectively. The proportion of males and urban was 67.1% and 67.5%, respectively. From 1999 to 2015, the crude mortality rate was from 12.10/100 000 to 12.58/100 000. The ASR was from 11.04/100 000 to 7.24/100 000. The average annual YLL number was 29 625.83 person-years and the rate was 3.09 person-years per thousand people. From 1999 to 2015, the crude mortality rate and the PYLL of gastric cancer in Tianjin were stable (the AAPC was 0.34% and -0.24%, all values >0.05). The ASR showed a downward trend (AAPC=-2.58%, 0.001). From 1999 to 2015, the ASR of gastric cancer in Tianjin showed a downward trend, and the YLL of gastric cancer was stable.
分析1999年至2015年天津市胃癌死亡率及寿命损失年数（YLL）的长期趋势。1999年1月1日至2015年12月31日，从天津市死亡监测系统收集胃癌死亡数据。胃癌死亡的纳入标准采用国际疾病分类（ICD）第9版（1999 - 2002年）中的编码151以及ICD第10版（2003 - 2015年）中的C16进行编码。根据Segi世界标准人口计算胃癌的粗死亡率和年龄标准化死亡率（ASR）。按照世界卫生组织疾病负担的标准方法计算YLL。采用Joinpoint回归计算平均年度百分比变化（AAPC）以表明胃癌死亡率和YLL的趋势。1999年至2015年，天津市有20000例胃癌死亡病例。胃癌死亡在0 - 44岁、45 - 64岁以及65岁及以上人群中的比例分别为4.9%、30.4%和64.8%。男性和城市人群的比例分别为67.1%和67.5%。1999年至2015年，粗死亡率从12.10/10万升至12.58/10万。ASR从11.04/10万降至7.24/10万。平均每年YLL数为29625.83人年，率为每千人3.09人年。1999年至2015年，天津市胃癌的粗死亡率和PYLL稳定（AAPC分别为0.34%和 - 0.24%，均P>0.05）。ASR呈下降趋势（AAPC = - 2.58%，P = 0.001）。1999年至2015年，天津市胃癌的ASR呈下降趋势，且胃癌的YLL稳定。
