目的分析高钠饮食对我国胃癌疾病负担的影响情况,为胃癌高危人群防治策略优化提供参考。方法采用2019全球疾病负担研究(global burden of disease study 2019,GBD 2019)中的中国胃癌疾病负担数据,以Joinpoint回归模型分析1990—2019年...目的分析高钠饮食对我国胃癌疾病负担的影响情况,为胃癌高危人群防治策略优化提供参考。方法采用2019全球疾病负担研究(global burden of disease study 2019,GBD 2019)中的中国胃癌疾病负担数据,以Joinpoint回归模型分析1990—2019年我国高钠饮食所致胃癌死亡率和伤残调整生命年(disability‐adjusted life‐years,DALYs)的变化及其趋势,以平均年度变化百分比(average annual percent change,AAPC)和95%可信区间(confidence interval,CI)表示各相邻年份间构成比的变化量。结果我国高钠饮食所致胃癌死亡例数和粗死亡率自1990年的27226例(占我国胃癌总死亡例数8.913%)、2.300/10万上升至2019年的37131例(占我国胃癌总死亡数8.808%)、2.611/10万,但DALYs率从62.048/10万下降至61.434/10万。1990—2019年我国居民高钠饮食所致胃癌合计标化死亡率逐年下降1.716%,其中男性逐年下降1.221%,女性逐年下降2.661%(均P<0.001);标化DALYs率逐年下降2.005%,其中男性逐年下降1.495%,女性逐年下降3.067%。各年龄组DALYs率均呈下降趋势(均P<0.01),其中55~59岁居民的DALYs率下降速度最快(AAPC=-2.547%),80岁及以上居民的DALYs率下降速度较慢(AAPC=-0.702%)。我国居民高钠饮食所致胃癌标化DALYs率逐年下降(AAPC=-2.005%),下降速度高于中低和低社会人口指数(socio‐demographic index,SDI)国家或地区(AAPC=-1.209%、-1.119%),但低于全球以及高、中高、中SDI国家或地区的平均水平(AAPC=-2.094%、-3.166%、-2.361%、-2.090%)。结论我国居民高钠饮食所致的胃癌疾病负担逐年下降但水平仍较高,男性高于女性,老年男性人群是重点干预人群,应加强减盐饮食干预,以降低胃癌疾病负担。展开更多
