1990-2019年中国白内障患病率和伤残调整寿命年的趋势分析OACSTPCD

·AIM:To assess the evolving burden of cataracts in China from 1990 to 2019. ·METHODS:Data on disease burden related to cataracts in China were retrieved from the Global Burden of Disease(GBD)2019 study based on large public databases.Utilizing data from the GBD 2019 study,we extracted information on cataract-related disease burden in China from extensive public databases.Analysis of prevalence and disability-adjusted life years(DALYs)associated with cataracts in China was conducted based on GBD 2019 findings.The variable characteristics of age-standardized prevalence rates(ASPR)and age-standardized DALYs rates(ASDR)in China and its neighboring countries were also explored. ·RESULTS:Between 1990 and 2019,the number of prevalent cases of blindness and vision loss caused by cataracts in China increased by 223.54％,and the corresponding DALYs raised by 142.14％.Over the past 30 years,females exhibited higher age-standardized prevalence and DALYs rates compared to males.Meanwhile,individuals aged 65 to 84 years were found to be more susceptible to cataracts than other age groups.Compared with neighboring countries,China ranked from the 9th position in 1990(867.09,95％UI:761.36 to 975.42,per 100 000 population)to the 11th in 2019(991.56,95％UI:861.52 to 1131.04,per 100 000 population)in ASPR,while from the 9th in 1990(65.85,95％UI:46.39 to 89.41,per 100 000 population)to the 10th position in 2019(59.16,95％UI:41.70 to 80.15,per 100 000 population)in ASDR.However,on a global scale,China maintained relatively low ASDR and ASPR for cataracts in 2019. ·CONCLUSION:The study highlights a substantial rise in the prevalence and DALYs associated with blindness and vision loss due to cataracts from 1990 to 2019 in China,and underscores the urgent need for increased early screening of cataracts,particularly among the elderly and females.
