Background Vision loss is an important public health issue in China, but a detailed understanding of national and regional trends in its prevalence and causes, which could inform health policy, has not been available. This study aimed to assess the prevalence, causes, and regional distribution of vision impairment and blindness in China in 1990 and 2019.Methods Data from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 were used to estimate the prevalence of moderate and severe vision impairment and blindness in China and compare with other Group of 20 (G20) countries. We used GBD methodology to systematically analyse all available demographic and epidemiological data at the provincial level in China. We compared the age-standardised prevalences across provinces, and the changes in proportion of vision loss attributable to various eye diseases in 1990 and 2019. We used two different counterfactual scenarios with respect to population structure and age-specific prevalence to assess the contribution of population growth and ageing to trends in vision loss. FindingsIn 2019, the age-standardised prevalence was 2•57% (uncertainty interval [UI] 2•28-2•86) for moderate vision impairment, 0•25% (0•22-0•29) for severe vision impairment, and 0•48% (0•43-0•54) for blindness in China, which were all below the global average, but the prevalence of moderate and severe vision impairment had increased more rapidly than in other G20 countries from 1990 to 2019. The prevalence of vision loss increased with age, and the main causes of vision loss varied across age groups. The leading causes of vision impairment in China were uncorrected refractive error, cataract, and macular degeneration in both 1990 and 2019 in the overall population. From 1990 to 2019, the number of people with moderate vision impairment increased by 133•67% (from 19•65 to 45•92 million), those with severe vision impairment increased by 147•14% (from 1•89 to 4•67 million), and those with blindness increased by 64•35% (from 5•29 to 8•69 million); in each case, 20•16% of the increase could be explained by population growth. The contributions to these changes by population ageing were 87•22% for moderate vision impairment, 116•06% for severe vision impairment, and 99•22% for blindness, and the contributions by age-specific prevalence were 26•29% for moderate vision impairment, 10•91% for severe vision impairment, and -55•04% for blindness. The prevalence and specific causes of vision loss differed across provinces.Interpretation Although a comprehensive national policy to prevent blindness is in place, public awareness of visual health needs improving, and reducing the prevalence of moderate and severe vision impairment should be prioritised in future work.
BackgroundOn December 29, 2019, the health authorities in Hubei Province and Wuhan City received a report of a cluster of pneumonia cases of unknown etiology from a local hospital, and all four patients were employees of the Wuhan Huanan Seafood Wholesale Market (HN market for short) (1). By January 8, 2020, Chinese authorities had identified a new virus 2019 novel coronavirus (2019-nCoV) linked with the outbreak of disease, which has been named novel coronavirusinfected pneumonia (NCIP) (2). On 15 January, the National Health Commission (NHC) issued guidelines for the diagnosis, treatment, prevention, and control of NCIP. These guidelines directed case monitoring, reporting, diagnosis, treatment, management, close contact management, and laboratory testing. On
Background To analysis the death and disease burden caused by high sugar-sweetened beverages intake in China from 1990 to 2019. Methods Data were obtained from the 2019 Global Burden of Disease Study. We analyzed the death cases caused by high sugar-sweetened beverages intake in China and provinces from 1990 to 2019, as well as the disease burden (including disability-adjusted of life year), years of life lost and years lived with disability, and compared the changes of death in 1990 and 2019. Results In 2019, the number of deaths attributed to sugar-sweetened beverages in China reached 46 633 with an increase of 95% compared with 1990. The proportion of deaths caused by excessive consumption of carbon-containing beverages increased from 0.34% in 1990 to 0.46% in 2019, an increase of 35%. In 2019, the top five provinces in China with more deaths caused by excessive intake of sugary beverages were Shandong, Henan, Hebei, Hunan and Guangdong, with the number of death cases 4337, 3881, 3010, 2762 and 2611, respectively. Conclusions The number of deaths and disease burdens caused by high sugar-sweetened beverages intake in China has increased significantly over the past three decades. The burden of disease due to high intake of sugary beverages varies widely from province to province. We suggest that attention should be paid to the problem of excessive intake of high sugar-sweetened beverages for Chinese population. In addition to regular monitoring and investigation of sugar-sweetened beverage intake, comprehensive measures should be taken in China’s sugar control work.
Background: Neck pain (NP) is a common musculoskeletal problem; however, the prevalence and years lived with disability (YLD) of NP in China are still unclear. This study sought to estimate the age-, sex-and province-specific prevalence and YLD of NP in China.Methods: Adopting the methodology framework and analytical strategies used in the Global Burden of Disease (GBD), Injuries, and Risk Factors Study (2017), the prevalence and YLD of NP in China were estimated by age, sex, year, and provinces/regions. Results:In China, the age-standardized point prevalence rate of NP was 4,532.6 per 100,000 persons in 1990 and increased slightly to 4,634.4 per 100,000 persons in 2017. The prevalence of NP was 48.0 million in 1990 and rose dramatically to 87.3 million in 2017 (an increase of 82.0%). The age-standardized YLD rate of NP was 454.0 per 100,000 persons in 1990, and there was a slight increase to 465.6 per 100,000 persons in 2017. The all-age YLD of NP was 4.8 million in 1990 and rose to 8.8 million in 2017 (which represents an increase of 81.1%). In 1990, NP was the third leading cause of YLD in China, and in 2017, NP was the leading cause of disability burden.Conclusions: This study estimated the prevalence and disability burden of NP in China. NP is currently the leading cause of disability burden in China; however, it is currently inadequately recognized and should receive further attention and be subject to further research.
