Disease burden of cirrhosis caused by non-alcoholic fatty liver disease in China, 1990-2021: a comparative analysis with global trends
-
摘要:
目的 分析1990—2021年中国与全球非酒精性脂肪性肝病(non-alcoholic fatty liver disease, NAFLD)疾病负担变化趋势,并预测未来趋势,为防治策略提供依据。 方法 基于2021年全球疾病负担数据库,提取1990—2021年中国与全球NAFLD的发病率、死亡率、伤残调整生命年等数据。采用Joinpoint回归模型计算年度变化百分比(annual percentage change, APC)和平均年度变化百分比(average annual percentage change, AAPC),利用贝叶斯年龄-时期-队列模型(Bayesian age-period-cohort model, BAPC)预测2035年疾病负担。 结果 2021年中国NAFLD的年龄标化发病率(621.18/10万)高于全球水平(592.78/10万)。1990—2021年中国标化伤残调整生命年(disability-adjusted life year, DALY)率(AAPC=-1.99%)和标化死亡率(AAPC=-1.72%)持续下降,但标化发病率呈上升趋势(AAPC=0.74%)。Joinpoint回归分析结果显示:(1)标化死亡率,1990—2015年阶段性下降,2015年后变化不显著;(2)标化发病率,1990—1999年缓慢上升(APC=0.19%~0.56%),2000—2004年短暂下降(APC=-1.30%),2004年后再次上升(APC=0.78%~2.21%);(3)标化DALY率,1990—2015年总体下降(APC=-2.63%~-1.54%),2015年后趋于平稳。全球标化DALY率和死亡率呈波动下降,但降幅小于中国。BAPC模型预测,至2035年,中国发病人数将增长26.50%,死亡人数下降38.43%;中国标化发病率增速(0.74%)低于全球,标化死亡率将继续下降。 结论 1990—2021年中国NAFLD负担总体下降,但发病人数持续增长,预测到2035年,中国NAFLD患者的死亡数将下降,发病数将上升。提示需加强代谢性疾病早期干预,完善慢性肝病防治体系,以降低疾病流行风险。 Abstract:Objective To analyze the trends in the disease burden of non-alcoholic fatty liver disease (NAFLD) and other chronic liver diseases-related cirrhosis in China and globally from 1990 to 2021, predicting future trajectories, and providing evidence for prevention strategies. Methods Data on incidence, mortality, and disability-adjusted life years of NAFLD and other chronic liver diseases-related cirrhosis were extracted from the Global Burden of Disease database. Joinpoint regression analysis was used to calculate annual percentage changes (APC) and average annual percentage changes (AAPC). A Bayesian age-period-cohort (BAPC) model was applied to project disease burden up to 2035. Results In 2021, China exhibited a higher age-standardized incidence rate of NAFLD and other chronic liver diseases-related cirrhosis (621.18 per 100 000) compared to the global average (592.78 per 100 000). From 1990 to 2021, China experienced declines in age-standardized DALY rate (AAPC=-1.99%) and mortality rate (AAPC=-1.72%), while the age-standardized incidence rate increased (AAPC=0.74%). Joinpoint analysis revealed: For standardized mortality rate, it phased declines during 1990-2015, with insignificant changes post-2015; For standardized incidence rate, it gradual rise from 1990-1999 (APC=0.19%-0.56%), followed by a transient decline (APC=-1.30%) in 2000-2004, and renewed increases post-2004 (APC=0.78%-2.21%); For DALY rate, the overall reduction during 1990-2015 (APC=-2.63%--1.54%), stabilizing after 2015. Globally, age-standardized DALY and mortality rates declined with fluctuations but at slower rates than in China. BAPC projections indicated that by 2035, incident cases in China will rise by 26.50%, while deaths will decrease by 38.43%. The age-standardized incidence growth rate in China (0.74%) will remain significantly lower than the global rate, and age-standardized mortality is projected to continue declining. Conclusions Despite reductions in age-standardized disease burden in China from 1990 to 2021, the growing number of incident cases of NAFLD and related cirrhosis highlights persistent challenges in controlling these conditions. Prioritizing early intervention for metabolic disorders and strengthening prevention systems for chronic liver diseases are critical to mitigating future risks. -
