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.
ABSTRACT
Background: The prevalence of skin diseases has increased over the last few decades, and they contribute to a significant burden on health-care systems across the world. Aims/Objective: This report looks at the burden of skin and subcutaneous diseases in terms of years lived with disability and age-standardised years lived with disability in India using the Global Burden of Disease Study results from 2017. Methods: Data were obtained from the Global Burden of Disease online interactive tool. Updated estimates of the world’s health for 359 diseases and injuries and 84 risk factors from 1990 to 2017 are available in this interactive tool. Results: Years lived with disability due to skin and subcutaneous diseases accounted for 4.02% of the total years lived with disability in India in 2017. There was an increase of 53.7% in all age standardised years lived with disability for all the skin and subcutaneous diseases from 1990 to 2017. Among skin and subcutaneous diseases, dermatitis contributed maximum years lived with disability (1.40 million; 95% uncertainty interval, 0.82–2.21) in 2017, followed by urticaria (1.02 million; 95% uncertainty interval, 0.06–1.44) with percentage increases of 48.9% and 45.7% respectively. Conclusion: The burden due to infectious skin diseases (e.g., scabies, fungal skin disease and bacterial skin disease) and non-infectious diseases (e.g., dermatitis, urticaria and psoriasis) has increased over the past three decades, however the age-standardised years lived with disability for leprosy, scabies, fungal infections, sexually transmitted infections and non-melanoma skin cancer (basal cell carcinoma) has decreased. The high burden of skin and subcutaneous diseases demand that they be given due importance in the national programmes and health policy of India.
ABSTRACT
ObjectiveTo analyze the disease burden in Sichuan Province in 2010 and 2020， and to provide reference for disease prevention and control. MethodsMonitoring data on causes of death in Sichuan Province in 2010 and 2020 were collected. Disability-adjusted life years （DALY）， years of life lost （YLL） and years lived with disability （YLD） were calculated to assess the disease burden in Sichuan Province. ResultsIn 2020， DALY was 7.004 0 million years， among which YLL and YLD were 3.719 6 million and 3.284 4 million， respectively. Compared with 2010， the total DALY in 2020 increased by 8.27%， most of which came from the increase of YLL （16.66%）. In 2020， the standardized total DALY rate was 69.91‰， which decreased by 9.87% compared with 2010. Specifically， the rate decreased by 15.87% for females and 5.28% for males. In 2020， the burden of DALY disease in the elderly over 60 years old increased by 34.55% compared with 2010. The burden of infectious and maternal diseases decreased the most， and the standardized DALY rates of male and female in 2020 decreased by 47.03% and 55.50% compared with 2010， respectively. Injury was the next most important factor， which decreased by 32.97% in males and 26.92% in females. The standardized DALY rate of chronic diseases increased by 5.41% in males and decreased by 10.67% in females. In 2020， compared with 2010， the standardized DALY rate of males increased significantly in diabetes （82.02%）， nervous system and mental disorders （26.31%）， and cardiovascular and cerebrovascular diseases （19.86%）. Among women， significant increases were seen in diabetes mellitus （54.74%）， neurological and mental disorders （35.52%）， and musculoskeletal and connective tissue diseases （23.51%）. ConclusionThe overall disease burden in Sichuan Province shows a declining trend， mainly attributed to the decrease in infectious and maternal diseases and injuries. The disease burden among people over 60 years old has increased significantly， with the focus on chronic diseases such as diabetes， cardiovascular and cerebrovascular diseases， nervous system and mental disorders， and musculoskeletal and connective tissue diseases.
ABSTRACT
Objective To assess the burden of clonorchiasis and identify its temporal and spatial changes in China, thus to provide insights into the control and prevention of the diseases. Methods The disability-adjusted life years (DALYs) was employed as the primary indicator for the disease burden. The prevalence data of Clonorchis sinensis infection were obtainted from the three national surveys on important human parasitic diseases in China, conducting during the period from 1988 to 1922, from 2001 to 2004 and from 2014 to 2016, respectively, and the demographic data from National Bureau of Statistics of China. DALYs of clonorchiasis were calculated and the temporal changes were analyzed at both national and provincial levels, using the disability weight (DW) obtained from a community study in China. Sensitivity analysis was carried out to compare the resulted DALYs of China calculated under the method adopted in this study and that calculated with other commonly used methods. Results The national burden of clonorchiasis was 489174.04 [95% confidence interval (CI): (391648.87, 597509.87)] DALYs in China in 2016, indicating 0.36 [95% CI: (0.28, 0.43)] DALYs per 1 000 populations. The regions with a high burden of clonorchiasis were concentrated in southern China and northeastern China, and the provinces with the three highest burdens of clonorchiasis included Guangxi Zhuang Autonomous Region, Guangdong Province and Heilongjiang Province, which accounted for 91.18% of total burdens of clonorchiasis in China. During the periods of the three national surveys on important human parasitic diseases in China, the national burden of clonorchiasis was found to show a tendency of first rise and then decrease in China; however, the burden of clonorchiasis has recently shown a tendency towards a rise in Guangxi Zhuang Autonomous Region, Heilongjiang Province and Jiangxi Province. Sensitivity analysis showed that the calculation of diseases burden with age-stratified prevalence of clonorchiasis was similar to that of our method without age stratification; however, the burden estimates calculated only based on the DW of the severe symptoms were much lower than our estimates. Conclusions The burden of clonorchiasis is high in China, with a large regional difference. Recently, the overall burden of clonorchiasis has shown a tendency of decline in China; however, there is a tendency towards a rise in some provinces. Therefore, the control of clonorchiasis requires more adaptations to local circumstances.

RESUMEN Objetivo: Determinar la pérdida de años de vida saludables (AVISA) por trastornos mentales y enfermedades del sistema nervioso en Medellín, de 2006 a 2012. Métodos: Estudio descriptivo, con fuente de información secundaria bajo lineamientos teóricos del Estudio la Carga Global de la Enfermedad (CGE). Para calcular los Años Potenciales de Vida Perdidos (APVP), se empleó información de las estadísticas vitales; para los Años de Vida Ajustados por Discapacidad (AVD), la de morbilidad de los Registros Individuales de Prestación de Servicios de Salud (RIPS), de consulta externa y otras investigaciones. Los AVISA se obtuvieron de sumar los APVP y AVD. Resultados: En Medellín, durante el septenio, de 1.242.407 AVISA por trastornos mentales y enfermedades del sistema nervioso, la mayor carga se debió a discapacidad (99,39%). Las mujeres aportaron más AVISA (70,22%). El 81% de los AVISA se concentraron en el grupo de 15 a 59 años. Los trastornos que mayor carga representaron fueron, en este orden, el trastorno depresivo unipolar (81%), el Alzheimer y otras demencias (4,82%), la esquizofrenia (3,45%) y los trastornos por consumo de drogas (2,78%). Conclusiones: Se sustenta un importante incremento de la carga de la enfermedad por trastornos mentales y enfermedades del sistema nervioso, lo que debe llamar la atención de los tomadores de decisiones sobre la política pública del municipio, ya que estos problemas de salud pueden significar un gran aumento en los costos de atención en salud.
ABSTRACT Objective: To determine the healthy life years (HLY) lost as a result of mental disorders and nervous system diseases in Medellin from 2006 to 2012. Methods: Descriptive study using a secondary information source according to the Global Burden of Disease (GBD) framework. To calculate the years of potential life lost (YPLL), we used vital statistics data; to calculate disability-adjusted life years (DALY), we used morbidity data from individual records managed by health service providers, outpatient clinics and other research studies. HLY are the sum of YPLL and DALY. Results: In Medellin, from 2006 to 2012, out of 1,242,407 HLY related to mental disorders and nervous system diseases, the vast majority (99.39%) were due to disability. Most HLY were found in females (70.22%) and 81% were found in people aged 15 to 59. The disorders representing the greatest burden were unipolar depressive disorder (81%), Alzheimer's disease and other types of dementia (4.82%), schizophrenia (3.5%) and drug use disorders (2.78%). Conclusions: Our results indicate a significant increase in the disease burden due to mental disorders and nervous system diseases. Public policy decision-makers in the city of Medellin should take note, as health problems of this type can result in a substantial rise in healthcare costs.

Objective To analyze the burden of intestinal infectious diseases in Jining city from 2009 to 2016, determine the epidemic trends and the high-risk groups in this area, so as to provide evidence for the prevention and control of intestinal infectious diseases. Methods The intestinal infectious diseases case information were collected from the Infectious Diseases Surveillance Information Reporting System. Based on these data, the incidence rate, the years lived with disability (YLDs) and the intensity of YLDs of intestinal infectious diseases was calculated. Results From 2009 to 2016, the annual incidence rate of intestinal infectious diseases in Jining city was 128.81/100 000, the annual incidence rate of subtype diseases in the descending order were other infectious diarrhea (74.74/100 000), hand-foot-and-mouth disease (49.15/100 000), bacillary dysentery (3.65/100 000), hepatitis E (0.57/100 000), acute hemorrhagic conjunctivitis (0.37/100 000) and hepatitis A (0.34/100 000). The highest incidence of intestinal infectious diseases was at May to August. The total YLDs caused by intestinal infectious diseases were 593.04 person-years, including 372.31 person-years for males and 220.73 person-years for females. The YLDs ranked in descending order were of hand-foot-mouth disease (326.88 person-years), other infectious diarrhea (235.74 person-years), hepatitis E (10.65 person-years), bacillary dysentery (10.09 person-years), hepatitis A (7.71 person-years), and acute hemorrhagic conjunctivitis (1.97 person-years), and the corresponding intensity of YLDs were 0.489, 0.353, 0.016, 0.015, 0.012, and 0.003 person-years /100 000, respectively. Conclusions The hand-foot-and-mouth disease and the other infectious diarrhea were the main intestinal infectious diseases subtypes prevailed in Jining city from 2009 to 2016, whose incidence was highest in the season of summer, and the preschool children and elderly people were the high-risk populations. According to its incidence characteristic, relevant government departments can take effective measures to prevent and control the intestinal infectious diseases in Jining city.
ABSTRACT
Objective To compare the approaches used for the assessment of disability adjust life years (DALYs) for advanced schistosomiasis japonica, so as to provide scientific evidence for accurate assessment of the burden of advanced schistosomiasis japonica. Methods The patients with advanced schistosomiasis japonica receiving treatment and assistance programs in Hunan Province in 2017 were enrolled, and the years lived with disability (YLD) for the patients with advanced schistosomiasis japonica was calculated using the common global burden of disease (GBD) estimation method, the modified GBD method with addition of common syndromes of advanced schistosomiasis japonica, and the quality of life assessment method. Results The YLDs of patients with advanced schistosomiasis japonica, the mean YLDs per capita, and the percentages of YLD were 673.94, 728.77 person-years and 1 761.99 person-years; 0.181, 0.196 person-years and 0.474 person-years; and 10.61, 11.48 person-years per 100 thousand persons and 27.75 person-years per 100 thousand persons with the common GBD method, modified GBD method and the quality of life method, respectively. The YLDs of the patients with advanced schistosomiasis japonica in Hunan Province estimated with the modified GBD method and the quality of life method were 8.14% and 2.61 times higher than that with the common GBD method. Of the major symptoms included in the calculation, the 5 symptoms with the greatest contribution to the burden of advanced schistosomiasis japonica included ascites, moderate anemia, severe anemia, diarrhea and hematochezia. Conclusion The quality of life method may more comprehensively assess the YLDs in patients with advanced schistosomiasis japonica than the common and modified GBD methods.

ABSTRACT
Objective To evaluate the family and economic burden of chronic Schistosomiasis japonica. Methods Relevant information on 226 chronic schistosomiasis patients from four surveillance sites in Yangxin county was collected. A questionnaire survey was conducted on 219 of them who agreed to corporate. Family burden was estimated with standard Family Burden Scale of Disease (FBS). Direct economic burden was calculated by questionnaire survey. Human capital method combined with Years Lived with Disability (YLDs) was adopted to evaluate the indirect economic burden. Results The positive rates on the dimensions of family economic burden and family entertainment were 54.8 percent and 47.0 percent respectively. The remaining dimensions were lower than 40.0 percent. Results of the questionnaire survey among 219 chronic Schistosomiasis patients showed that the total economic burden was 353 480.59 Chinese Yuan, which was 1614.07 Yuan per person. The direct and indirect economic burden were 61 679 and 291 801.59 Yuan respectively. The average direct and indirect economic burden when counted on money losses, were 281.64 and 1332.43 Yuan per person, respectively. Conclusion The family burden caused by chronic Schistosomiasis japonica was serious, economically in particular. With regard to the income level of local residents, the economic burden of chronic Schistosomiasis was heavy to every household with indirect economic burden accounted for major proportion, suggesting close attention to be paid.
