Status and trend of refractive disorder burden in China based on a global perspective / 公共卫生与预防医学

ABSTRACT

Objective Based on the global burden of disease (GBD) study data, to analyze the current situation and changing trend of refractive disorders in China by comparing Japan, India, the United States, the United Kingdom and the world. Methods The prevalence, years lived with disability (YLD) rate of refractive disorders from 1990 to 2019 were obtained from the global health exchange (GHDx）database. The disease burden and change trend of refractive disorders were analyzed using Joinpoint and other software. Results In 2019, the number of refractive disorders in China exceeded 27 million, with the prevalence and YLD rate were 19.18‰ and 89.40/100,000 respectively. From 1990 to 2019, the prevalence and YLD rate of refractive disorders showed an increasing trend globally (except India), with the largest increase in China (up by 53.21% and 53.96% respectively). The age standardized YLD rates in China, Japan, the United States, and the United Kingdom were all lower than the global average level, but China's age standardized YLD rates were higher than the developed countries (Japan, the United States, and the United Kingdom). Conclusion From 1990 to 2019, there was a certain gap between China and developed countries in the control of refractive disorders. Therefore, it is necessary to understand the disease status from a global perspective in order to better prevent and control refractive disorders in the future.
