Anos Potenciais de Vida Perdidos devido à COVID-19, segundo a raça/cor e gênero, no Brasil, entre 2020 e 2021 / Years of Potential Life Lost due to COVID-19 according to race/color and gender in Brazil between 2020 and 2021

Resumo A mortalidade provocada pela pandemia da COVID-19 tem produzido impactos aos indicadores de Anos Potenciais de Vida Perdidos (APVP) em nível mundial. Objetiva-se estimar os APVP devido à mortalidade por COVID-19, segundo sexo, faixa etária e raça/cor, no período de março de 2020 a dezembro de 2021, no Brasil. Foram caracterizadas as mortes por COVID-19, estimadas e comparadas as taxas e razão de taxas padronizadas de APVP, a média de anos potenciais de vida não vividos (APVNV) e a idade média do óbito (IMO). No geral, foram perdidos 13.776.969,50 anos potenciais de vida, o que determinou uma perda média de 22,5 anos potenciais não vividos. Houve maior perda de anos potenciais de vida nos homens (58,12%) e nas faixas etárias de 0 a 59 anos nas populações negra (58,92%) e indígena (63,35%), enquanto nas faixas etárias de 60 anos e mais foi observada maior perda de APVP nas populações branca (45,89%) e amarela (53,22%). As mulheres registraram as maiores IMO, com exceção das mulheres indígenas. Homens brancos (1,63), pardos (1,59) e pretos (1,61) tiveram as maiores taxas em comparação às mulheres brancas. Apesar da COVID-19 ter tido maior impacto em idosos, foram as populações negra e indígena na faixa de menos de 60 anos quem teve maior perda de anos potenciais de vida.

Abstract Mortality caused by the COVID-19 pandemic has impacted indicators of Years of Potential Life Lost (YPLL) worldwide. This study aimed to estimate the YPLL due to mortality caused by COVID-19, according to sex, age group, and race/color in Brazil, from March 2020 to December 2021. Deaths caused by COVID-19 were characterized, in which the rates and ratios of standardized YPLL rates, the average number of years of potential life lost (ANYPLL), and the average age at death (AAD) were estimated and compared. Overall, 13,776,969.50 potential years of life were lost, which resulted in an average loss of 22.5 potential years not lived. A greater loss of potential years of life was identified in men (58.12%) and in the age groups from 0 to 59 years in the black (58.92%) and indigenous (63.35%) populations, while in the age groups of 60 years and over, a greater loss of YPLL was observed in the white (45.89%) and yellow (53.22%) populations. Women recorded the highest ADD, with the exception of indigenous women. White men (1.63), brown men (1.59), and black men (1.61) had the highest rates when compared to white women. Although COVID-19 has a greater impact on the elderly, it was the black and indigenous populations under the age of 60 who had the greatest loss of potential years of life.

Años de vida perdidos y distribución espacial de la mortalidad por incidente vial en Medellín, 2010-2020

Objetivo: Estimar los años potenciales de vida perdidos y la distribución espacial de la mortalidad por incidente vial según modo de transporte en Medellín 2010-2020, como línea base para la implementación de la estrategia Visión Cero, de la Organización Mundial de la Salud, en la movilidad de la ciudad. Metodología: Estudio retrospectivo y descriptivo de corte transversal, con fuente secundaria. El cálculo de los años potenciales de vida perdidos se hizo tomando como edad límite la esperanza de vida al nacer de Colombia, según año y género. El análisis espacial se realizó a partir de la dirección del incidente; la representación de la densidad de Kernel fue por el método de clasificación estándar-cuantil, y las zonas de influencia se crearon por el método búfer de anillos múltiples, con distancias de 500 y 1000 metros. Resultados: Medellín, entre 2010 y 2020, registró 2988 muertes por incidente vial. Quienes más murieron fueron los peatones, con 1423 (47,6 %) muertes, seguidos por los motociclistas, con 1295 (43,3 %). Los años potenciales de vida perdidos fueron 98 787. Las comunas de mayor concentración en muerte de peatones fueron: Candelaria, Buenos Aires y Manrique; en motociclistas, la mayor concentración se evidenció en el sistema vial del río. Por zonas de influencia, los peatones fallecidos en un radio de 1000 metros del sistema vial del río fueron 688 (49,8 %), y los motociclistas, 636 (52,2 %). Conclusión: Los motociclistas fueron quienes murieron más jóvenes y más años dejaron de vivir. Politraumatismos son diagnósticos constantes de muerte, pero lesiones en cabeza, cráneo y tórax son más letales en peatones y motociclistas.

Objective: To estimate the potential years of life lost and the spatial distribution of mortality from road incidents by mode of transport in Medellín 2010-2020, as a baseline for the implementation of the Vision Zero strategy of the World Health Organization in the city's mobility. Methodology: This is a retrospective and descriptive cross-sectional study, with a secondary source. The calculation of the potential years of life lost was made using the life expectancy at birth in Colombia as the age limit, according to year and gender. The spatial analysis was carried out from the direction of the incident; Kernel density was represented by the standard-quantile classification method, and the zones of influence were created by the multiple ring buffer method, with distances of 500 and 1000 meters. Results: Between 2010 and 2020, Medellín registered 2,988 deaths due to road incidents. Those who died the most were pedestrians, with 1,423 (47.6%) deaths, followed by motorcyclists, with 1,295 (43.3%). Potential years of life lost were 98,787. The zones (comunas) with the highest concentration of pedestrian deaths were: Candelaria, Buenos Aires and Manrique; in motorcyclists, the highest concentration was evidenced in the river road system. By areas of influence, pedestrians killed within a radius of 1,000 meters from the river road system were 688 (49.8%), and motorcyclists, 636 (52.2%). Conclusion: Motorcyclists were the ones who died the youngest and the most years they stopped living. Polytrauma is a constant diagnosis of death, but injuries to the head, skull and thorax are more lethal in pedestrians and motorcyclists.

Economic burden of liver disease in Colombia

Introduction: Liver diseases have a significant impact on global morbidity and mortality rates, primarily attributed to cirrhosis and hepatocellular carcinoma. However, the true extent of their impact on patients, healthcare systems, and countries is often underestimated. Materials and methods: This descriptive, cross-sectional study aimed to determine the economic burden associated with premature deaths caused by cirrhosis and primary liver cancer. The economic assessment was conducted by analyzing potentially productive years of life lost (PPYLL) due to liver diseases in Colombia between 2009 and 2016. Results and conclusions: The total burden of liver disease accounted for 687,861 disability-adjusted life years (DALYs). Men experienced a higher number of years of life lost from mortality (YLL), while women had a greater number of years lived with a disability (YLD). The economic burden of deaths caused by cirrhosis and primary liver cancer exceeded USD 8.6 million, highlighting the urgency to enhance intervention strategies ranging from promotion and prevention to timely diagnosis and treatment.

Introducción: la enfermedad hepática representa una de las principales causas de morbimortalidad a nivel mundial, principalmente por cirrosis y hepatocarcinoma; sin embargo, se subestima su impacto para el paciente, sistema de salud y el país. Materiales y métodos: estudio descriptivo de corte transversal que determinó la carga económica asociada a las muertes prematuras por cirrosis y tumores primarios del hígado, mediante la valoración económica de los años productivos de vida potencialmente perdidos (APVPP) en Colombia y de enfermedad hepática en Colombia entre 2009 y 2016. Resultados y conclusiones: la carga total de enfermedad hepática representó 687,861 años de vida saludable perdidos ajustados por discapacidad (AVAD), los hombres con mayores años de vida perdidos por muerte prematura (APMP) y las mujeres con mayores años vividos con discapacidad (AVD). Las muertes por cirrosis y tumores primarios del hígado representan una carga económica que supera los 8,6 millones de dólares, lo cual refleja la necesidad de fortalecer las estrategias de intervención desde la promoción y prevención hasta el diagnóstico y tratamiento oportuno.

Mortality and years of life lost of lung cancer among residents in Pudong New Area of Shanghai from 1995 to 2021 / 上海预防医学

ObjectiveTo investigate the epidemiological traits and potential years of life lost associated with lung cancer mortality among inhabitants of Shanghai's Pudong New Area from 1995 to 2021， in order to serve as a reference for developing intervention approaches. MethodsThe death surveillance system was used to gather statistics on lung cancer deaths. Crude mortality rate （CMR）， standardized mortality rate （SMR）， potential years of life lost （PYLL）， average years of life lost （AYLL）， annual percent change （APC） of the lung cancer deaths were analyzed. The impact of age-structural and non-age-structural factors on changes in lung cancer mortality was quantified using difference decomposition. ResultsThe CMR and SMR of lung cancer among residents in Pudong New Area between 1995 and 2021 were 58.21/105 and 26.75/105， respectively. The CMR of lung cancer increased over the years （APC=1.91%， 95%CI=1.60%‒2.30%； Z=11.487， P<0.001）， and the SMR of lung cancer declined over the years （APC=-1.50%， 95%CI=-1.80%‒-1.20%； Z=-9.006， P<0.001）. Age structure factors and gender factors contributed to the increase of lung cancer mortality， while non-population age structure factors overall appeared to play a protective role which might be related to the improvements in factors such as tobacco control and environmental management. The PYLL of lung cancer was 160 296 person years， the PYLL rate was 2.24‰， and the AYLL was 3.86 years per person. ConclusionAge structure factors are a significant contributor to the disease burden and result in the increase in the crude lung cancer mortality rate of Pudong residents of shanghai. Comprehensive monitoring， preventive， and control methods should be implemented.

Tonstruction of AHI based on the integrating health risks of exposure to air pollution and ambient temperature in Tianjin / 公共卫生与预防医学

Objective To construct an air health index (AHI) based on the exposure-response relationships of air pollution and ambient temperature with the years of life lost (YLL) in Tianjin. Methods The time series database of air pollution, meteorological factors, and non-accidental YLL from 2014-2019 in six urban areas of Tianjin were established. The data from 2014 to 2017 were used as the construction set to establish the exposure-response relationships of air pollution and ambient temperature with non-accidental YLL and establish the AHI model. The data from 2018 to 2019 were used as the validation set for verifying AHI. The generalized additive model (GAM) and weighted quantile sum (WQS) model were used to establish the exposure-response relationship between air pollution mixtures and non-accidental YLL. The distributed lag nonlinear model (DLNM) was fitted to assess the exposure-response relationship between ambient temperature and non-accidental YLL. Based on these obtained coefficients, the AHI and air quality health index (AQHI) were built. By comparing the associations between AHI, air quality health index (AQHI), and air quality index (AQI) with daily mortality and YLL and model goodness of fit to evaluate the validity of AHI. Results The formula for AHIt=EYLLt,air pollution+ambient temperature/475.11*10. The validation results showed that each IQR increase in AHI was associated with a higher increase in non-accidental mortality and YLL (10.61% and 353.37 person-year) compared with the corresponding values of AQHI and AQI. In addition, the model goodness of AHI was better than AQHI and AQI model. Conclusion Compared with AQHI and AQI, the AHI based on the integrating health effects of air pollution and ambient temperature has a better health risk prediction ability.

Disease burden of benign prostatic hyperplasia in China, Japan and South Korea from 1990 to 2019: a comparative study / 现代泌尿外科杂志

【Objective】 To analyze the disease burden of benign prostatic hyperplasia (BPH) in China, Japan and South Korea from 1990 to 2019, so as to provide scientific basis for rational allocation of health resources. 【Methods】 Data were obtained from the Global Burden of Disease Study 2019. The incidence, prevalence and years lived with disability(YLD)were used to analyze the burden, and the average annual percent change and annual percent change were calculated. 【Results】 The incidence, prevalence and YLD rate in China were much higher than those in Japan and South Korea. The crude incidence in China, Japan and South Korea increased by 2.56%, 1.49% and 3.59% per year from 1990 to 2019, the crude prevalence rate increased by 2.70%, 2.34% and 4.03%, and the crude YLD rate increased by 2.68%, 2.33% and 4.04%. After age standardization, the disease burden in China decreased with time, but the trend was not significant, and the standardized rate in Japan and Korea increased significantly with time. The disease burden of BPH increased with age, and those aged 60 to 84 years had the highest burden. In addition, the disease burden increased with the increase of socio-demographic index (SDI) in all three countries. 【Conclusion】 The disease burden of BPH was very heavy in China, Japan and South Korea, especially in China. Males aged 60 to 84 years were the high-risk group. Targeted intervention should be adopted for these population.

Disease burden of deaths attributable to occupational injuries in China from 1990 to 2019 / 环境与职业医学

Background Occupational injuries are one of the leading causes of death or disability in occupational populations. According to the World Health Organization and the International Labour Organization, occupational injuries were the occupational contributor responsible for the largest loss of disability-adjusted life years (DALY) globally in 2016. Objective To analyze the burden of deaths attributed to occupational injuries in Chinese population from 1990 to 2019, and provide a reference for further construction of occupational injury surveillance system. Methods Using the results and data of the Global Burden of Disease 2019 (GBD 2019), this study estimated the burden of deaths attributable to occupational injuries by year, sex, and age groups, and the indicators included deaths, years of life lost (YLL), mortality, and YLL rates. Age-standardized rates of deaths and YLL rates were calculated using a world standard population presented by GBD 2019. Annualized rate of change (ARC) was use to evaluate changes in the indicators over time. All results were presented as point estimates with 95% uncertainty intervals (95%UI). Results In 2019, the deaths attributable to occupational injuries among women in China accounted for 33.16% of that among world's women, their YLL accounted for 31.88%, and the two indicators among Chinese men accounted for 17.98% and 17.09%, respectively. Compared with 1990, the standardized mortality rate and the standardized YLL rate attributable to occupational injuries in China in 2019 decreased, among which the ARCs of the standardized mortality rate in the whole population, men, and women were −0.68 (95%UI: −0.78, −0.51), −0.68 (95%UI: −0.80, −0.47), and −0.68 (95%UI: −0.82, −0.46), respectively. The ARCs of the standardized YLL rate in the whole population, men, and women were −0.68 (95%UI: −0.78, −0.51), −0.67 (95%UI: −0.80, −0.48), and −0.68 (95%UI: −0.81, −0.44), respectively. Absolute values of the ARCs of the standardized mortality rate and the standardized YLL rate attributable to occupational injuries from 1990 to 2010 were higher than those from 2010 to 2019. The ARCs of the standardized YLL rate for road injuries, falls, and drowning from 1990 to 2010 were −0.55 (95%UI: −0.67, −0.36), −0.57 (95%UI: −0.73, −0.38), −0.77 (95%UI: −0.84, −0.63), and the ARCs from 2010 to 2019 were −0.27 (95%UI: −0.46, −0.02), −0.07 (95%UI: −0.34, −0.26), −0.06 (95%UI: −0.32, −0.29), respectively. In 2019, the standardized mortality rate attributable to occupational injuries among Chinese men was 5.68/100000 (95%UI: 3.89/100000, 8.23/100000), and the standardized YLL rate was 286.27/100000 (95%UI: 197.58/100000, 411.38/100000); the standardized mortality rate attributable to occupational injuries among Chinese women was 1.55/100000 (95%UI: 0.99/100000, 2.36/100000), and the standardized YLL rate was 80.85/100000 (95%UI: 51.61/100000, 122.07/100000). Conclusion From 1990 to 2019, the burden of deaths attributable to occupational injuries in China is declined, but the rate of decline is slowed down in the last decade. The burden of deaths attributable to occupational injuries among women in China still accounts for a high proportion of the global burden among women. The burden of deaths attributable to occupational injuries among Chinese men is higher than that among Chinese women.

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.

Introducción: El reciente incremento de la prevalencia de la diabetes mellitus en Cuba sucedió con mayor celeridad, y las políticas encaminadas a su control requieren de su cuantificación sistemática. Objetivo: Identificar las diferencias en Cuba, según provincia y sexo, de los años de vida saludable perdidos por la diabetes mellitus en el 2015. Métodos: En el estudio de extensión nacional se obtuvieron los años de vida saludable perdidos como resultado de la suma de los años perdidos de vida potencial por mortalidad prematura y los años de vida perdidos por morbilidad y otros indicadores para identificar la mortalidad temprana en el año 2015. Resultados: En todas las provincias los índices de años de vida saludable perdidos por morbilidad superaron los de mortalidad prematura con predominio del sexo femenino, mientras en la mayoría de las provincias, las edades de las defunciones fueron más tempranas en el masculino. Las diferencias halladas permitieron agrupar a Artemisa, La Habana, Mayabeque, Matanzas, Villa Clara, Cienfuegos, Santi Spíritus y Camagüey, con los mayores promedios de años perdidos por morbilidad y fallecimientos más tardíos, y al resto de las provincias cubanas, con los menores años perdidos por morbilidad, pero con defunciones en edades más tempranas. Conclusiones: Las pérdidas de años de vida saludable difieren según el sexo y la provincia. Este conocimiento permite la identificación de diferentes patrones de morbimortalidad útiles para orientar las acciones de prevención y control de la enfermedad para cada territorio(AU)

Introduction: The recent increase in the prevalence of diabetes mellitus in Cuba occurred more rapidly, and policies aimed at its control require systematic quantification. Objective: To identify the differences in Cuba, according to province and sex, of the years of healthy life lost due to diabetes mellitus in 2015. Methods: The national extension study collected data on the healthy years of life lost as a result of the sum of years lost from potential life due to premature mortality and years of life lost due to morbidity and other indicators to identify early mortality in 2015. Results: In all provinces, the rates of years of healthy life lost due to morbidity exceeded those of premature mortality with a predominance of women, while in most provinces, the ages of death were earlier in the male sex. The differences found allowed to group Artemisa, Havana, Mayabeque, Matanzas, Villa Clara, Cienfuegos, Santi Spíritus and Camagüey provincesn with the highest averages of years lost due to morbidity and later deaths, and the rest of the Cuban provinces, with the lowest years lost due to morbidity, but with deaths at younger ages. Conclusions: Losses of years of healthy life differ by sex and province. This knowledge allows the identification of different patterns of morbidity and mortality useful to guide the prevention and control actions of the disease for each territory(AU)

Situación del suicidio en Antioquia-Colombia durante los años 2016 y 2017: Resultados de los datos de vigilancia epidemiológica

Introducción: la vigilancia epidemiológica del suicidio en una región permite identificar los patrones, la distribución y las características con que ocurre y sentar las bases de intervenciones para prevenirlo. Objetivo: describir la situación del suicidio en Antioquia para el periodo 2016-2017. Métodos: estudio descriptivo basado en datos del Sistema de Vigilancia Epidemiológica de Lesiones de Causa Externa del Instituto Nacional de Medicina Legal y Ciencias forenses. Se calcularon las tasas de suicidio y los años de vida potencialmente perdidos (AVPP) y se describieron las circunstancias del evento. Resultados: hubo 425 suicidios en 2016 y 419 en el 2017, con una tasa de suicidio de 6,50 y 6,34 por 100.000 habitantes/año respectivamente, y 16.446,8 AVPP para 2016 y 16.019,94 para 2017. La mayor parte de los suicidios se presentó en el sexo masculino, en los grupos de edad jóvenes, residentes en área urbana y estado civil soltero. Con respecto a las características del suicidio, el mecanismo más frecuentemente utilizado fue la asfixia mecánica seguido por el envenenamiento, en cerca del 40% de los casos se estableció un evento vital desencadenante como los conflictos de pareja, y se presentaron con mayor frecuencia los días domingo y lunes y en la noche y madrugada. Conclusión: las tasas de suicidio en Antioquia se han incrementado en 2016 y 2017 con respecto a años anteriores. Es más frecuente en hombres y en edades económicamente productivas, lo que explica los altos AVPP. La descripción de las características del suicidio podría facilitar la discusión de intervenciones preventivas.

Summary Background: Identifying the patterns, distribution, and characteristics of suicide in a region is possible with epidemiological surveillance which may lay the foundations for suicide prevention. Objective: To describe the situation of suicide in Antioquia during the period 2016-2017. Methods: Descriptive study based on data from the Epidemiological Surveillance System for External Cause Injuries of the National Institute of Legal Medicine and Forensic Sciences. Suicides rates and Years of Life Lost (YLL) were calculated and the circumstances of the event were described. Results: There were 425 suicides in 2016 and 419 in 2017, with a suicides rate of 6.50 and 6.34 per 100,000 inhabitants/year respectively, and 16,446.8 YLL for 2016 and 16,019.94 YLL for 2017. Most of the suicides occurred in males, in young age groups, urban residents and single marital status. Regarding the characteristics of suicide, the most frequently used mechanism was mechanical asphyxia followed by poisoning, in about 40% of cases a triggering life event was established, such as partner conflicts, and were more frequent on Sunday and Monday and at night and early morning. Conclusion: The incidence of suicide in Antioquia increased in 2016 and 2017 compared to previous years. It was more frequent in economically productive ages, which explains the high YLL. The description of the characteristics of suicide may facilitate the discussion of preventive interventions.

Seasonal variation in health effects of particulate matter in Tianjin / 环境与职业医学

Background Adverse health effects associated with particulate matter have been demonstrated, but findings on seasonal variation in the health impacts are inconsistent. Objective To explore potential seasonal variation in particulate matter (PM2.5 and PM10) associated daily non-accidental mortality and corresponding years of life loss (YLL) in Tianjin. Methods The daily data of non-accidental deaths, air pollution, and meteorological factors in Tianjin from 2014 to 2019 were collected. A generalized additive model, with adjusting selected confounding factors such as temperature, relative humidity, long-term trends, day of the week, and holiday, was used to quantitatively evaluate the relationships of PM2.5 and PM10 with daily non-accidental deaths and YLL. Results The effects of PM2.5 and PM10 on daily non-accidental mortality and corresponding YLL were statistically significant in full year, spring, summer, and autumn (except for the effect of PM10 on non-accidental YLL in spring), but not statistically significant in winter. The non-accidental mortality and it's 95%CI increased by 0.28% (0.11%-0.44%) and 0.24% (0.11%-0.36%) in full year, 0.44% (0.11%-0.77%) and 0.17% (0.00%-0.33%) in spring, 1.32% (0.50%-2.16%) and 2.15% (1.54%-2.76%) in summer, and 0.68% (0.30%-1.06%) and 0.57% (0.28%-0.87%) in autumn for every 10 µg·m−3 increase in PM2.5 and PM10 concentrations, respectively; the corresponding YLL and it's 95%CI increased by 7.41 (2.42-13.07) and 5.75 (1.94-9.57), 13.11 (3.00-23.22) and 2.88 (−2.82-8.59), 34.66 (11.92-57.40) and 48.12 (31.48-64.75), and 16.13 (4.57-27.70) and 12.60 (3.56-21.65) person-years, respectively. When adopting the limits in the Global Air Quality Guidelines (2021) as the reference, excess deaths and YLL caused by PM2.5 and PM10 exposure were the greatest in summer. The excess deaths and it's 95%CI were 5.38 (5.08-5.69) and 8.62 (7.95-9.28), and the excess YLL and it's 95%CI were 112.23 (105.79-118.67) and 156.94 (44.99-168.89) person-years, respectively. Conclusion The effects of particulate matter on non-accidental mortality and corresponding YLL may vary seasonally in Tianjin with the greatest effects in summer, suggesting that the health protection related to particulate matter should be strengthened in summer.

Identification of meteorological variables as predictors for forecastinghealth risks of high temperatures / 预防医学

Objective@#To identify the most appropriate meteorological variable for forecasting the health risk of high temperatures.@*Methods@#The surveillance on causes of death, meteorological data and surveillance on air quality among registered residents in Ningbo City, Zhejiang Province during the period between May and October from 2013 to 2019 were collected. The association models of daily minimum temperature, average daily temperature, daily maximum temperature, daily minimum heat index, average daily heat index, daily maximum heat index, average daily apparent temperature and torridity index with deaths and years of life lost (YLL) were created using time series analysis and distributed lag non-linear models, and the model fitting effect was evaluated using the minimum Akaike information criterion (AIC) procedure. The most appropriate meteorological variable for forecasting gender-, age- and mortality-specific health risks of high temperatures was identified.@*Results@#A total of 120 628 deaths were reported during the study period, with daily deaths of 94 cases, and daily YLL rate of 19.74 person-years/105. Except for daily minimum heat index and torridity index, the exposure-response relationships between other six meteorological variables and deaths and overall YLL rate all appeared a “J” shape. The lowest AIC values and the optimal model fitting effects were measured for the association models between average daily temperature and whole populations, females, subjects at ages of 65 years and older, and deaths and YLL rates due to circulatory diseases and respiratory diseases.@*Conclusion@#High model fitting effects are observed between average daily temperature and deaths and YLL rates, which are more suitable for forecasting the health risk of high temperature.

Characteristics of death causes and disease burden in Pingshan District of Shenzhen in 2019-2020 / 公共卫生与预防医学

Objective To analyze the characteristics of death and disease burden of residents in Pingshan District of Shenzhen City from 2019 to 2020 and provide data support for disease prevention and control. Methods The data of death surveillance and demography were collected. The causes of death were classified and coded according to ICD-10. The crude mortality, standardized mortality and potential years of life lost were calculated. Results From 2019 to 2020, 910 people died in Pingshan district.The average age of death was 64.94(47.06 - 82.34) years, the crude mortality was 102.04/100 000, the standardized mortality was 263.97/100 000, and the average life expectancy was 86.00 years. 558 men died and 352 women died , the crude mortality were 113.72/100 000 and 87.76 /100 000 , the standardized mortality rate 313.05/100 000 and 211.97/100 000 ; the average life expectancy were 84.66 years and 87.55 years . The crude mortality of male was higher than that of female (χ2=14.594, P<0.001). The standardized mortality of men was also higher than that of women. The top three causes of death in the whole population, men and women were circulatory system diseases, malignant tumors, diseases and injury from high to low. And the top three diseases with standardized potential life lost years and standardized potential life lost rate from high to low were injury, circulatory system diseases and malignant tumors. Conclusion Circulatory system diseases, malignant tumors, injury are the main causes of death and the three kinds of diseases with the heaviest disease burden in Pingshan District of Shenzhen city. Men are the key population for prevention and control. The prevention and control of the above three kinds of diseases should be done to reduce the mortality of local population.
