Global Burden of Cardiovascular Disease Attributable to High Temperature in 204 Countries and Territories from 1990 to 2019 / 生物医学与环境科学（英文）

OBJECTIVE@#This study aimed to estimate spatiotemporal variations of global heat-related cardiovascular disease (CVD) burden from 1990 to 2019.@*METHODS@#Data on the burden of heat-related CVD were derived from the Global Burden of Disease Study 2019. Deaths and disability-adjusted life years (DALYs) were used to quantify heat-induced CVD burden. We calculated the age-standardized mortality rate (ASMR) and DALY rate (ASDR) per 100,000 population to compare this burden across regions. Generalized linear models were applied to evaluate estimated annual percentage changes (EAPC) for temporal trends from 1990 to 2019. The correlation between the socio-demographic index (SDI) and age-standardized rate was measured using the Spearman rank test.@*RESULTS@#Heat-induced CVD caused approximately 90 thousand deaths worldwide in 2019. Global ASMR and ASDR of heat-related CVD in 2019 were 1.17 [95% confidence interval ( CI): 0.13-1.98] and 25.59 (95% CI: 2.07-44.17) per 100,000 population, respectively. The burden was significantly increased in middle and low-SDI regions and slightly decreased in high-SDI regions from 1990 to 2019. ASMR showed an upward trend, with the most considerable increase in low-latitude countries. We observed a negative correlation between SDI and EAPC in ASMR ( r s = -0.57, P < 0.01) and ASDR ( r s = -0.59, P < 0.01) among 204 countries.@*CONCLUSION@#Heat-attributable CVD burden substantially increased in most developing countries and tropical regions.

Disease burden on road injury in the Chinese population, in 1990 and 2013 / 中华流行病学杂志

Objective To explore the disease burden of road injuries in China.Methods The results of Global Burden of Disease 2013 including death rate,disability-adjusted of life years (DALY),years of life lost due to premature mortality (YLL),years lived with disability (YLD),were used to describe the burden caused by road injuries in 2013 and the trends from 1990 to 2013,in China.Results In 2013,there were 313 676 deaths caused by traffic accidents in China.Death rate,rates on DALY,YLL and YLD were 22.52 per 100 000,1 076.54 per 100 000,971.21 per 100 000 and 105.34 per 100 000,respectively.Rates on deaths,YLL and YLD appeared higher in males,pedestrians than in females and other types of road travelers.Burden of injuries caused by traffic accidents was seen higher in those aged 15 to 49-year-old.From 1990 to 2013,the overall death rate on road injuries increased by 0.54 per 100 000 in China,with an increase of 2.34 per 100 000 and 0.81 per 100 000,respectively in males and pedestrians.The rates on DALY,YLL and YLD decreased by 164.21 per 100 000,115.06 per 100 000 and 49.06 per 100 000,respectively.Conclusions During the past 20 years,achievements had been made on road injury prevention and control,with the decrease of disease burden caused by road accidents.Males,young adults and pedestrians should be called for more attention to prevent road injuries.

Defining the Scope of Chronic Non-communicable Diseases under the Perspective of the Global Disease Burden / 中国卫生经济

Based on the global burden of disease classification, to explore the scope of chronic diseases. Methods:Searching relevant literature and books to screen and remove the acute non-communicable diseases among the non-communicable diseases which is the second category of global burden of disease ( GBD) classification. Results: Acute non-communicable diseases mainly concentrated on the acute inflammatory diseases, it also existed in other acute diseases which are not caused by infection. Conclusion: To screen and remove the acute non-communicable diseases in the non-communicable diseases could define the scope of non-communicable chronic diseases on certain extent, which has certain significance for the workers who study all chronic diseases.

The disease burden attributable to smoking in the state of Rio de Janeiro, Brazil in 2000

INTRODUCTION: Smoking is one of the main risk factors for morbidity and mortality. An estimated 59 million (4.4 percent) disability-adjusted life years were lost due to smoking throughout the world in 2000. OBJECTIVE: To estimate the disease burden attributable to smoking in the State of Rio de Janeiro, Brazil, for the year 2000. METHODS: Based on estimates of smoking prevalence and relative death risks, the smoking-attributable fraction was calculated for each selected cause, by age and gender. The disease burden attributable to smoking was estimated by multiplying the fractions by the corresponding disability-adjusted life years. RESULTS: In the State of Rio de Janeiro, 7 percent of all disability-adjusted life years were due to smoking. For individuals 30 or more years old, the fraction increased to 10.6 percent (13.6 percent in males and 7.5 percent in females). Chronic obstructive pulmonary disease, ischemic heart disease, cerebrovascular disease, and tracheal, bronchial, and lung cancer accounted for 32.2 percent, 15.7 percent, 13.2 percent, and 11.1 percent of the estimated total DALYs, respectively, amounting to 72.2 percent of the smoking-attributable disease burden. DISCUSSION: Limitations related to parameter estimates were not unique to this study, and therefore should not compromise the comparability of our results. Outcomes were similar to those obtained in other countries, despite methodological differences. CONCLUSION: Smoking is an important risk factor and places a significant disease burden on Rio de Janeiro, Brazil, showing a pattern similar to that observed in high income countries.
