Trends in prevalence and disability-adjusted life years of cataract in China from 1990 to 2019 / 国际眼科杂志(Guoji Yanke Zazhi)

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.

Prevalence of the Non-Communicable disease triad in hilly state of Uttarakhand: Evidences from National Family Health Surveys

India is facing epidemiological transition towards non communicable diseases and morbidities due to NCD triad of obesity, hypertension and diabetes. The risk factors contributing to chronic disease and NCD triad are lifestyle changes, poor dietary habits, lack of physical activity, tobacco/alcohol consumption. These risk factors are however modifiable and preventable. This article reviews secondary data of NFHS-4 and NFHS-5 to analyse trends of obesity, hypertension and diabetes among urban and rural population of Uttarakhand from 2015 to 2021.

The impact of the COVID-19 pandemic on people living with HIV in Zimbabwe

The COVID-19 pandemic was reported from March 2020 in Zimbabwe. COVID-19 containment measures which included repeated lockdowns have disrupted community interactions, reduced working hours, restricted travel and restricted HIV services for people living with HIV (PLHIV), among others. The study adopted a cross-sectional design. Both qualitative and quantitative data were collected in all the 10 provinces and analysed. A sample size of 480 was calculated for the cross-sectional survey. Secondary data on HIV early warning indicators from 2018 to 2021 were extracted from 20 randomly selected health facilities and used for modelling. Mathematical modelling was conducted to assess the impact of COVID-19 on PLHIV. AIDS-related deaths increased from 20 100 in 2019 to 22 200 in 2020. In addition, there were significant years of life lost (yLLs) from premature mortality and years of life lost due to disability (yLDs) from COVID-19. Prevalence of COVID-19 among PLHIV was 4%. COVID-19 vaccination coverage was 64%, which is higher than the national average of 42%. Stress and breach of confidentiality as ARV medicines were given out in open spaces and fear of contracting COVID-19 were the perceived psychological issues. COVID-19 disrupted HIV service provision, increased AIDS-related deaths and caused psychological challenges

Burden of syphilis in Brazil and federated units, 1990-2016: estimates from the Global Burden of Disease Study 2019

ABSTRACT Background: Syphilis is a chronic infectious disease that has created challenging situations for humanity for centuries. Transmission can occur sexually or vertically, with great repercussions on populations, particularly among women and children. The present study presents information on the main burden imposed by syphilis generated by the Global Burden of Disease (GBD) Study 2019 for Brazil and its 27 federated units. Methods: We described the metrics of incidence, deaths, years of life lost (YLLs), years lived with disability (YLDs), and disability-adjusted life years (DALYs), standardized by age and per 100,000 inhabitants, from 1990 to 2019, and we compared the disease burden between the years 1990 and 2019. Results: In Brazil, the disease burden increased between 2005 and 2019 for all metrics. Although a higher incidence of syphilis was found among women in 2019, DALYs [YLLs (males: 15.9%; females: 21.8%), YLDs (males: 25.0%; females: 50.0%), and DALYs (males: 16.2%; females: 22.4%)] were higher among men. In 2019, the highest DALY rate per 100,000 inhabitants was observed in individuals aged above 50 years. The State of Maranhão presented the highest values of DALYs {1990: 165.2 [95% uncertainty interval (UI) 96.2-264.4]; 2005: 43.8 [95% UI 30.3-62.4]; 2019: 29.1 [95% UI 19.8-41.1]} per 100,000 inhabitants in the three years analyzed. Conclusions: The burden of syphilis has increased in recent years. Men presented higher DALYs, although the incidence of the disease was higher in women. Syphilis affects a large number of people across all age groups, causing different degrees of disability and premature death (DALYs).

Lung cancer in Mexico: findings from the Global Burden of Disease Study, 1990-2016 / Cáncer de pulmón en México: hallazgos del estudio de Carga Global de la Enfermedad 1999-2016

Abstract: Objective: To show lung cancer (LC) mortality and disability-adjusted life years (DALYs) in Mexico. Materials and methods: With the visualization tools at the Global Burden of Disease Study website, we analyzed LC mortality and disability-adjusted life years (DALYs) by state, sex, sociodemographic index (SDI), age, and risk factors between 1990 and 2016. Results: Mortality rate decreased from 13.9 to 9.1 per 100 000 between 1990 and 2016. This reduction is greater among men. However, deaths by LC rose from 5 478 to 8 470. DALYs rate also decreased. Northern states with higher SDI face a larger burden from LC but exhibited greater reductions compared with southern, less developed states. The burden of LC is concentrated among older population. Smoking is the main risk factor for LC. Conclusions: The burden by LC has decreased but is differential between states. LC threatens financially both the health system and individuals, since an important fraction of the population is not protected.

Resumen: Objetivo: Mostrar la mortalidad y los años de vida saludables (Avisas) perdidos por cáncer de pulmón (CP) en México. Material y métodos: Con la herramienta de visualización del estudio de la Carga Global de la Enfermedad, se analizó mortalidad y Avisas por CP según diferentes criterios entre 1990 y 2016. Resultados: La tasa de mortalidad disminuyó de 13.9 a 9.1 por 100 000. Dicha reducción fue mayor entre hombres. Las muertes por CP crecieron de 5 478 a 8 470. La tasa de Avisas se redujo. La carga del CP se concentra en grupos de edad avanzada. Los estados del norte, con mayor nivel sociodemográfico, enfrentan mayor carga, pero presentaron mayores reducciones comparados con estados menos desarrollados. Fumar es el principal factor de riesgo para CP. Conclusiones: La carga por CP ha disminuido pero es diferencial entre estados. El CP amenaza financieramente el sistema de salud y la población, pues una fracción importante no está protegida.

Estimating the social and economic burden of road traffic injuries in the Philippines

@#<p style="text-align: justify;"><strong>BACKGROUND:</strong> Road traffic injuries (RTI) are a leading cause of morbidity and mortality globally. Despite underreporting, the scarce Philippine data suggest that RTI pose a significant health problem in the country. It is imperative, therefore, to accurately quantify the burden of RTI in the Philippines.</p><p style="text-align: justify;"><strong>OBJECTIVE:</strong> This study aimed to provide the first comprehensive baseline estimation of the socioeconomic burden of RTI in the Philippines for year 2014.</p><p style="text-align: justify;"><strong>METHODS:</strong> The study was a mixed method study design that utilized both primary and secondary data. These data were used to construct parameters needed for the modeling estimates. Measure of socioeconomic burden estimated were (1) economic costs, (2) disability-adjusted life years (DALYs), and (3) healthy life years (HeaLY).</p><p style="text-align: justify;"><strong>RESULT:</strong> Estimated deaths due to RTI in 2014 were 12,336 translating to 454,650 years life lost due to premature death. Injury episodes from RTI were estimated to be 2,798,088 in 2014 with 186,174 leading to admissions, translating to 56,224 years life lost to disability. The total DALY loss due to RTI in 2014 was estimated at 510, 874, while healthy life years lost were estimated to be 76,215,477.4. The estimated deaths and injuries for that year equaled to direct medical cost of PhP 1.213 B, productivity loss due to premature death of PhP 24.620 B, and productivity loss due to illness of PhP 685 M resulting to a total economic cost of PhP 26.519 B to the society.</p><p style="text-align: justify;"><strong>CONCLUSION:</strong> The findings indicate that RTI is an important public health concern in the Philippines with substantial economic and health burden. Investing in preventive measures will likely yield significant economic and health gains for the Philippines.</p>

Disability-Adjusted Life Years for Maternal, Neonatal, and Nutritional Disorders in Korea

Maternal and child health is an important issue throughout the world. Given their impact on maternal and child health, nutritional issues need to be carefully addressed. Accordingly, the effect of maternal, child, and nutritional disorders on disability-adjusted life years (DALYs) should be calculated. The present study used DALYs to estimate the burden of disease of maternal, neonatal, and nutritional disorders in the Korean population in 2012. For this purpose, we used claim data of the Korean National Health Insurance Service, DisMod II, and death data of the Statistics Korea and adhered to incidence-based DALY estimation methodology. The total DALYs per 100,000 population were 376 in maternal disorders, 64 in neonatal disorders, and 58 in nutritional deficiencies. The leading causes of DALYs were abortion in maternal disorders, preterm birth complications in neonatal disorders, and iron-deficiency anemia in nutritional deficiencies. Our findings shed light on the considerable burden of maternal, neonatal, and nutritional conditions, emphasizing the need for health care policies that can reduce morbidity and mortality.

Disability-adjusted Life Years (DALYs) for Mental and Substance Use Disorders in the Korean Burden of Disease Study 2012

The purpose of this study was to estimate the national burden of mental substance disorders on medical care utilization in Korea using National Health Insurance System (NHIS) data and updated disability weight, in terms of disability-adjusted life years (DALYs). For each of the 24 disorders, the incident years lived with disability (YLDs) was calculated, using NHIS data to estimate prevalence and incidence rates. The DisMod-II software program was used to model duration and remission. The years of life lost (YLLs) due to premature death were calculated from causes of death statistics. DALYs were computed as the sum of YLDs and YLLs, and time discounting and age weighting were applied. The year examined was 2012, and the subjects were divided into 9 groups according to age. In 2012, the Korean burden of mental and substance use disorders was 945,391 DALYs. More than 98% of DALYs were from YLDs, and the burden in females was greater than that in males, though the burden in males aged less than 19 years old was greater than that in females. Unipolar depressive disorders, schizophrenia, and anxiety disorders were found to be major diseases that accounted for more than 70% of the burden, and most DALYs occurred in their 30–59. Mental and substance use disorders accounted for 6.2% of the total burden of disease and were found to be the 7th greatest burden of disease. Therefore, mental and substance use disorders need to be embraced by mainstream health care with resources commensurate with the burden.

Disability-Adjusted Life Years (DALYs) for Injuries Using Death Certificates and Hospital Discharge Survey by the Korean Burden of Disease Study 2012

A system for assessing the burdens imposed by disease and injury was developed to meet healthcare, priority setting, and policy planning needs. The first such system, the Global Burden of Disease (GBD), was implemented in 1990. However, problems associated with limited data and assumed disability weightings remain to be resolved. The purpose of the present study was to estimate national burdens of injuries in Korea using more reliable data and disability weightings. The incidences of injuries were estimated using the Korean National Hospital Discharge Survey and the mortality data from the Korean National Statistical Office in 2010. Additionally, durations of injuries and age at injury onset were used to calculate disability-adjusted life years (DALY) using disability weightings derived from the Korean Burden of Disease (KBD) study. Korea had 1,581,072 DALYs resulting from injuries (3,170 per 100,000), which was 22.9% higher than found by the GBD 2010 study. Males had almost twice as heavy an injury burden as females. Road injury, fall, and self-harm ranked 1st, 2nd, and 3rd in terms of burden of injury in 2010. Total injury burden peaked in the forties, while burden per person declined gradually from early adulthood. We hope that this study contributes to the reliable evaluation of injury burden and a better understanding of injury-related health status using nation-specific, dependable data.

In both sexes the problems with diet contribute 12% of the burden. Conclusions. The epidemiological situation in Mexico, demands an urgent adaptation and modernization of the health system.

Carga de enfermedad por meningitis bacteriana, Cuba 2006 / Burden of disease due to bacterial meningitis, Cuba 2006

Introducción: la meningitis bacteriana constituye una preocupación para los médicos y los sistemas de salud en general de cualquier país, así como para los organismos internacionales. Objetivo: estimar las cargas por morbilidad y mortalidad por meningitis bacteriana en Cuba para 2006. Métodos: se utilizaron los datos de mortalidad y de incidencia de la encuesta epidemiológica de la Vigilancia Nacional de Meningitis Bacteriana del Instituto de Medicina Tropical "Pedro Kourí". Los procedimientos de estimación se basaron en las recomendaciones de la Organización Mundial de la Salud con el uso del DISMOD y las hojas de cálculos establecidas al efecto. Resultados: la carga global de meningitis bacteriana se estimó en 3527,26 años de vida ajustados por discapacidad (AVAD), lo que representó la pérdida de 31,3 años por cada 100 000 habitantes. La carga por morbilidad y mortalidad de meningitis bacteriana sin ponderar la secuela resultó 2056,25 años de vida ajustados por discapacidad, 55,9 por ciento correspondió sin agente etiológico identificado, seguida de las originadas por Streptococcus pneumoniae (30,9 por ciento), Neisseria meningitidis (9,5 por ciento) y por Haemophilus influenzae tipo b (3,6 por ciento). La carga por mortalidad fue aproximadamente 2 039 años de vida perdidos (AVP) por muerte prematura, o sea 57,8 por ciento. Los menores de 5 años aportaron la mayor carga global de años de vida ajustados por discapacidad y dentro de ellos S. pneumoniae el que generó la mayor carga. Conclusión: la carga por meningitis bacteriana resultó elevada y corroboró su alta utilidad para evaluar los problemas de salud.

Introduction: bacterial meningitis is a real concern for physicians and general health systems of any country as well as the international bodies. Objective: to estimate burdens of disease from morbidity and mortality caused by bacterial meningitis in Cuba during 2006. Methods: the mortality and the incidence data of the epidemiological survey from the National Surveillance of Bacterial Meningitis of "Pedro Kourí" Institute of Tropical Medicine were used. The estimation methods were based on the WHO recommendations by using the DISMOD and the required Excel spreadsheets. Results: the global burden of bacterial meningitis was estimated at a total of 3527.26 Disability Adjusted Lost Years (DALYs), which accounted for 31.3 years lost per 100 000 inhabitants. Morbidity and mortality burden of bacterial meningitis without sequel weighing was 2056.25 disability adjusted lost years, being the 55.9 percent caused by unidentified agent, followed by S. pneumoniae (30.9 percent), N. meningitidis (9.5 percent) and H influenza type b (3.6 percent). The mortality burden was 2 039 years of life lost from premature death, that is, 57.8 percent of the global burden. Children under five years of age contributed the biggest global burden of disability adjusted lost years, and S. penumoniae generated the biggest burden. Conclusion: the burden of bacterial meningitis was high. Burden of disease is an important measure to assess health problems.

Cervical cancer incidence and mortality in Mongolia / Монголын Анагаах Ухаан

Introduction. Cervical cancer is one of the most common cancers among women worldwide. Its mortality exemplifies health inequity, as its rates are higher in low & middle income countries (LMICs ), and in low socio-economic groups within countries. Around 80% of global cervical cancer cases are in LMICs. (WHO, 2008 ) Goal. To determine the prevalence, incidence and mortality for cervical cancer among Mongolian population Objectives: 1. To determine the trends of incidence and mortality for cervical cancer by regions among Mongolian population during 2000-2009 2. To estimate DALYs for cervical cancer in 2009 Materials and Methods: Data for this study were abstracted from Annual Reports of the National Cancer Registry for 2000-2009.I ncidence and mortality rates were calculated as mean annual numbers per 100,000 residents. Age-standardized incidence rates (ASRs) and age-standardized mortality rates (ASMRs) were calculated by the direct method by weighting age-specific incidence and mortality rates to the World Population. The DALY combines in one measure the time lived with disability and the time lost due to premature mortality: DALY = YLL + YLD YLL – years of life lost due to premature mortality YLD – years lived with disability. Results: last ten years, the trends have been increasing of the prevalence, incidence and mortality rate for cervical cancer in Mongolia. The cervical cancer incidence rates are the highest in Central and Eastern regions than other regions. The average burden of cervical cancer across all regions in 2009 was 2868 DALYs per 100000 population, of which about 30,9% was due to premature death and 69% non-fatal health outcomes. Conclusion: The incidence of cervical cancer is generally low in China, moderate in Japan and somewhat higher in Korea and Mongolia [11]. Need to estimate the DALYs for common cancers in Mongolia.

Los QALYs y DALYs como indicadores sintéticos de salud / QALYs and DALYs as synthetic indicators of health

This article is a revision of the genesis and use of the health synthetic indicators QALYs and DALYs. The chronology of their appearance is shown and similarities and differences between them stated. DALYs (Disability-Adjusted Life-Years) correspond to years of life that are adjusted by a certain level of disability experienced during a particular period of time. DALYs, by studying disease burden, summarize the impact of mortality and disability related to specific disease in different communities. On the other hand, QALYs (Quality-Adjusted Life-Years) summarize health results in an indicator that combines the number of years lived with the quality of life experienced over those years. QALYs and DALYs play a crucial role as results measures in economic evaluation studies (cost-effectiveness and cost-utility analysis) measuring the impact of actions or specific interventions in the reversion of disease burden (DALYs) and/ or the improvement of the quality of life and life expectancy of patients (QALYs). Their generic character allows the comparison of the impact of health interventions for different diseases.

En el presente artículo se revisa la génesis y uso de los indicadores sintéticos de salud QALYs y DALYs. Se muestra la cronología de su aparición y se establecen las semejanzas y diferencias entre los mismos. Los DALYs (Disability Adjusted Life Years) corresponden a los años de vida ajustados por la Discapacidad o AVADs por su sigla en español. Los DALYs resumen, mediante estudios de carga de la enfermedad, el impacto de la mortalidad y discapacidad asociada a enfermedades especificas, en distintas comunidades; en cambio los QALYs (Quality Adjusted Life Years) sintetizan los resultados de salud en un indicador que combina el número de años vividos con la calidad de vida experimentada durante esos años. QALYs y DALYs cumplen hoy un papel esencial como medidas de resultado en los estudios de evaluación económica (análisis de costo efectividad y costo utilidad) midiendo el impacto de acciones o intervenciones especificas para revertir la carga de la enfermedad (DALYs) y/o mejorar la calidad y esperanza de vida de pacientes (QALYs). Su carácter genérico permite comparar el impacto de intervenciones de salud entre diferentes enfermedades.

Aspectos metodológicos para estimar la carga de factores de riesgo ambientales / Methodological features to estimate the environmental risk factors burden

Se presentan por primera vez en una publicación nacional los conceptos y aspectos metodológicos más importantes relacionados con la adecuación del método general para estimar la carga de factores de riesgo, al caso particular de los factores de riesgo ambientales. Los trabajos fundamentales sobre este tema han sido desarrollados desde hace un poco más de 10 años por especialistas de la Organización Mundial de la Salud. Se ilustra el procedimiento con la estimación de la carga atribuible al factor de riesgo ambiental "agua y saneamiento" en Cuba. El objetivo del trabajo es contribuir a un mayor conocimiento y debate sobre estas técnicas, lo que eventualmente conduciría a su gradual aplicación y al uso inteligente de sus resultados en la toma de decisiones relacionadas con la salud ambiental.

This is the first time that in a national publication to appear the more important methodological concepts and features related to general method adjustment to estimate the risk factors burden, particularly the environmental ones. From approximately 10 years ago the WHO's specialist have made fundamental papers on this subject. Procedure is illustrated with the burden valuation attributable to "water and disinfection" as an environmental risk factor in Cuba. The aim of present paper is to contribute to a greater knowledge and debate on these techniques what possibly could to lead to its gradual application and to wise use of results in the decision-making related to environmental health.

Congenital toxoplasmosis and DALYs in the Netherlands

The calculation of disability-adjusted life years (DALYs) enables public health policy makers to compare the burden of disease of a specific disease with that of other (infectious) diseases. The incidence of a disease is important for the calculation of DALYs. To estimate the incidence of congenital toxoplasmosis (CT), a random sample of 10,008 dried blood spot filter paper cards from babies born in 2006 in the Netherlands were tested for Toxoplasma gondii-specific IgM antibodies. Eighteen samples were confirmed as positive for IgM, resulting in an observed birth incidence of CT of 1.8 cases per 1,000 live-born children in 2006 and an adjusted incidence of 2.0 cases per 1,000. This means that 388 infected children were born in 2006. The most likely burden of disease is estimated to be 2,300 DALYs (range 820-6,710 DALYs). In the previous calculations, using data from a regional study from 1987, this estimate was 620 DALYs (range 220-1,900 DALYs). The incidence of CT in the Netherlands is much higher than previously reported; it is 10 times higher than in Denmark and 20 times higher than in Ireland, based on estimates obtained using the same methods. There is no screening program in the Netherlands; most children will be born asymptomatic and therefore will not be detected or treated.
