1997—2017年中国人群慢性阻塞性肺病疾病负担趋势分析

Analysis on disease burden trend for chronic obstructive pulmonary disease in China from 1997 to 2017

目的了解我国因慢性阻塞性肺病(COPD)所致疾病负担以及既往变化趋势,为评价和制定COPD防控策略提供理论依据。方法基于2017年全球疾病负担研究公开数据和可视化平台收集数据,采用Excel 2019软件整理数据并描述性分析2017年我国因COPD所致疾病负担情况并与全球水平相比较,分析1997—2017年我国因COPD所致疾病负担情况的变化趋势并与各级社会人口学指数(SDI)国家平均水平比较。结果2017年我国因COPD所致伤残调整寿命年(DALYs)占全球总量的25.02%,其中95.29%为40岁以上中老年人群的损失。1997—2017年我国疾病负担总量呈下降趋势(年均下降率1.30%),但伤残损失生命年(YLDs)呈上升趋势(年均增长率0.82%)。截至2017年早死损失生命年(YLLs)仍为DALYs负担的主要来源(65.83%),且DALY率和YLL率仍高于世界平均水平。结论我国中老年人群因COPD所致YLLs负担值得重点关注。近年来我国公共卫生政策已取得一定成果,但距离高SDI国家仍存在较大差距,疾病负担仍十分沉重,政府仍需积极实施以预防为主的COPD防控策略。

Objective To understand the disease burden trend of chronic obstructive pulmonary disease(COPD)in China,and to provide the theoretical basis for the evaluation and formulation of prevention and control strategies of COPD.Methods Based on the global burden of disease research in 2017 and visualization platform,the data were collected;the burden of disease caused by COPD in China was described and analyzed by the software Excel 2019,and compared to the global level.The trend of burden of disease caused by COPD from 1997 to 2017 in China was analyzed and compared to the average national level of sociodemographic index(SDI)at all levels.Results In 2017,the disability adjusted life years(DALYs)caused by COPD in China accounted for25.02%of the global total,95.29%of them were the loss of middle-aged and elderly people over 40 years old.From 1997 to 2017,total burden of disease in China showed the decreasing trend(average annual decreasing rate:1.30%),but the years lived with disability(YLDs)showed an increasing trend(average annual growth rate:0.82%).In 2017,the burden of years of life lost(YLLs)was still the main source(65.83%)of DALYs.Moreover,DALY rate and YLL rate were significantly higher than average level in the world.Conclusion The burden of YLLs caused by COPD in middle-aged and old population of China is worthy of special attention.In recent years,public health policy of Chinese government has made certain achievements,but there is still a large gap between China and high SDI countries,and the disease burden is still very heavy.Therefore,the government agency still needs to actively implement the prevention and control strategy of COPD.
