ABSTRACT
Objective To understand the associations between changes of high air temperature and mortality in summer in 31 cities in China.Methods Daily mortality and meteorological data in 31 cities in China from January 1,2008 to December 31,2013 were collected.Distributed lag nonlinear model was used to evaluate the association between high air temperature change and mortality in early summer and late summer after controlling for the long-term trend and the effect of "day of week".Results The relative risk of high air temperature on mortality was higher in early summer,with relative risk in the range of 1.08-2.14 in early summer and 1.03-1.67 in late summer.In early summer,the influence of high temperature on mortality was mainly below 5th of percentile and above 50th of percentile,while in late summer it was mainly above 95th of percentile.The lag effect of high air temperature on mortality in early summer was 6 days,while the lag effect in late summer was only about 2 days.Conclusions Association existed between high air temperature and mortality.The influence of high air temperature on mortality in early summer was stronger than that in late summer.It is necessary to take targeted protection measures.
ABSTRACT
Objective@#To analyze the lung cancer deaths attributable to ambient PM2.5 exposure in China in 2016.@*Methods@#All data were from the Global Burden of Disease Study 2016 (GBD 2016). Multiple-source data, including satellite observation, ground measurement, chemical migration model simulation, etc., and the data integration model for air quality (DIMAQ) were used to estimate the grid-level exposure to ambient PM2.5. Data from the vital registry and cancer registry were used to establish statistical model to estimate the lung cancer deaths by province, age and gender. The lung cancer deaths attributable to PM2.5 were calculated based on the calculation of population attributable fraction (PAF). The GBD world population age structure was adopted to calculate age-standardized rates for comparison among provinces (including 31 provinces, autonomous regions and municipalities directly under the central government, as well as Hong Kong and Macao special administrative regions, excluding Taiwan of China).@*Results@#In 2016, the lung cancer deaths attributable to ambient PM2.5 exposure in China were 14.56×104 (95% uncertainty interval (UI): 9.63×104-19.55×104), accounting for 24.66% (95%UI: 16.38%-33.12%) of total lung cancer deaths. The lung cancer death rate attributable to PM2.5 increased with age, with the lowest among 25-29 age group (0.25/105, 95%UI: 0.17/105-0.34/105), the highest among ≥80 age group (90.70/105, 95%UI: 59.85/105-122.20/105). The lung cancer death rate attributable to PM2.5 among males (14.84/105, 95%UI: 9.78/105-19.93/105) was higher than that in females (6.21/105, 95%UI: 4.07/105-8.40/105). The age-standardized death rates (ASDR) of lung cancer attributable to PM2.5 among males and females in China were higher than the global average level. The attributable ASDR of lung cancer varied among provinces, highest in Shandong (13.51/105, 95%UI: 9.14/105-18.20/105) and lowest in Tibet (0.85/105, 95%UI: 0.44/105-1.51/105).@*Conclusion@#In 2016, the lung cancer deaths attributable to ambient PM2.5 exposure in China was heavy, and varied in different age groups, genders and provinces.

ABSTRACT
Objective To assess the mortality attributable to low fruit intake among people over 25 years old in China,2013,and its effect on life expectancy.Methods Based on data collected from China Chronic Disease and Risk Factor Surveillance in 2013,the average fruit intake in different genders and areas were calculated.Potential impact fraction (PIF) was used to examine the impact on deaths,mortality and life expectancy.Results The average daily fruit intake was (113.3 ± 168.9)g among people over 25 years old,with (103.6± 160.1) g for men and (122.7± 176.6) g for women,in China in 2013.Fruit intake for urban residents was significantly higher than that in rural residents and higher in eastern regions than that in central or western regions.Scores that attributable to low fruit intake accounted for 15.21％ of the total deaths and the population attributable fraction of inadequate intake of fruits to associated diseases was 35.00％.PIF for all the deaths in rural residents (16.50％)appeared higher than that of the urban residents (13.88％),and higher in the residents living in the eastern region (15.48％) than that in the central (16.27％) or western (13.75％) regions.Number of deaths that attributable to low fruit intake was 1.348 4 million.Deaths caused by related diseases appeared as:ischemic heart disease (472.5 thousands),hemorrhagic stroke (338.8 thousands),ischemic stroke (259.0 thousands),lung cancer (208.4 thousands),esophageal cancer (60.7 thousands),laryngeal cancer (5.4 thousands) and oral cancer (3.6 thousands).Numbers of all deaths and related diseases for urban residents were lower than that of the rural residents,with central regions (452.7 thousands) higher than that in the eastern (531.1 thousands) or western (364.6 thousands) regions.The average life expectancy loss caused by low fruit intake was 1.73 years,1.80 years for men and 1.58 years for women,in this country.Loss of life expectancy in the rural residents was higher than that of the urban residents,and higher in central regions than that in the eastern or western regions.Conclusions The intake of fruit was far lower than the recommended standard set for the Chinese people.Population attributable fraction was related to the associated diseases caused by inadequate intake of fruits which also made serious impact on life expectancy.
ABSTRACT
Objective To analyze the attribution of mortality and impact on life expectancy caused by insufficient physical activity in different gender and areas in adults aged ≥25 years among Chinese people.Methods Data from the programs related to Chinese death surveillence,risk factors of chronic survey,health outcomes of physical activity as well as relative risk (RR) on Global Burden of Disease (GBD) study were used.Population attributable fraction (PAF) of different health outcomes attributable to deaths that caused physical activity and the influence of life expectancy in adults aged ≥25 years in Chinese people were calculated.Results The overall PAF for all cause of death due to physical activity in adults aged ≥25 years was 4.24％,with 4.86％ in females and 3.82％ in males.The health outcomes of inadequate physical activity would include breast cancer,colorectal cancer,ischemic heart disease,ischemic stroke and diabetes with relative PAFs as 9.04％,13.96％,14.96％,17.80％ and 16.92％,respectively.The attribution of death on Physical activity was 388 954.The most attributed death was ischemic heart disease,followed by ischemic stroke.With the elimination of physical inactivity,the total life expectancy was expected to lose by 0.43 years,with 0.47 years in women,and 0.39 years in men.Conclusion The increase of physical activity may benefit on health condition so to reduce the burden of chronic diseases and increase the life expectancy.
ABSTRACT
Objective To analyze the death attributable to smoking and impact of life expectancy in China in 2013.Methods According to the characteristics of different diseases,we calculated the population attributable fractions of different diseases,death and impact of life expectancy which caused by smoking,using direct method (current smoking rate as exposure levels)and indirect method (smoking impact ratio as exposure levels),based on data from both programs of death surveillance and Chinese chronic disease risk factor surveillance of 2013.Results In 2013,smoking caused around 1.59 million deaths which accounted for 17.38％ of all deaths in China.Constituent ratio of death caused by smoking in males (23.66％) was much higher than that in females (8.30％).However,in urban areas (17.24％),it was slightly lower than that in rural areas (17.51％).Constituent ratio of death caused by smoking in the eastern regions appeared the lowest (16.81％),with western regions the highest (17.91％).In 2013,lung cancer,COPD and ischemia heart disease were the top three diseases causing deaths that related to smoking,but the top three population attributable fractions were lung cancer,COPD and nasopharyngeal carcinoma in China.In 2013,smoking caused a reduction of 2.04 years of life expectancy loss in China,with males in the western regions the highest (3.05 years).Conclusion Smoking is still an important public health problem in China.Tobacco-control-targeted programs in the heavily involved areas could reduce the number of deaths from related diseases that caused by smoking.
ABSTRACT
Objective To explore the effect of fime particulate matters with an aerodynamic diameter less than 2.5 μtm (PM2.5) on daily cardiovascular disease mortality in seven cities of China.Methods Daily average concentrations of PM2.5,cardiovascular disease mortality data and environmental data were collected from January 1,2013 to December 31,2015 in seven cities of China,including Shijiazhuang,Haerbin,Shanghai,Wuhan,Guangzhou,Chengdu and Xi'an.We linked generalized additive model with Quasi-Poisson distribution to evaluate the association between daily concentrations of PM2.5 and cardiovascular disease mortality at single-city level and multi-city level,after adjusting for the long-term and seasonal trend,as well as meteorological factors and the effect of "days of week".Results The single-pollutant model indicated that there were marked differences in association strength in these cities,among which the effect in Guangzhou was strongest.At multi-city level,a 10 μg/m3 increase of PM2.5 was associated with an increase of 0.315％ (95％CI:0.133％-0.497％) of daily cardiovascular disease mortality.From lag0 to lag2,the effect of PM2.5 on cardiovascular disease mortality decreased,while it was strongest on lag01.In the two-pollutant model,the estimated effect decreased in all the cities with the adjustments of SO2 or NO2.The insignificant combined results suggested that PM2.5 might have combined effect with other pollutants.Each 10 μg/m3 increase of PM2.5 was associated with increases of 0.371％ (95％CI:0.141％-0.600％) and 0.199％ (95％ CI:0.077％-0.321％) of cardiovascular disease mortality in males and females,respectively.The effect of PM2.5 on cardiovascular disease mortality increased with age and decreased with educational level,although the differences between different subgroups were insignificant.The dose-response relationship between PM2.5 and cardiovascular disease mortality was non-linear and non-threshold,with a steeper curve at lower concentrations.Conclusion The increases of PM2.5 concentration can result in the increase of daily cardiovascular mortality.
ABSTRACT
Objective@#To analyze the burden of disease attributable to low fruit intake among Chinese population aged ≥15 years old between 1990 and 2013.@*Methods@#We used data from the 2013 Global Burden of Disease Burden of Disease Study to study the situation in China. The population attributable fraction was calculated to estimate and compare the death and disability-adjusted life years (DALY) attributed to low fruit intake between 1990 and 2013 in China (excluded Taiwan, China). An average world population age structure of the period 2000-2025 was adopted to calculate age-standardized rates.@*Results@#Deaths attributable to low fruit intake accounted for 11.02% of all death in 2013, which were higher than it in 1990 (10.38%). In 2013, the number of deaths attributed to low fruit intake in China increased to 1 046 500 from 793 800 in 1990. From 1990-2013, the age-standardized death rate attributable to low fruit intake decreased from 113.04/100 000 to 79.80/100 000. DALYs caused by low fruit intake increased from 18.346 5 million in 1990 to 21.296 7 million in 2013. Compared with 1990, the age-standardized DALY rate attributed to low fruit intake decreased by 34.67%. In 2013, the top three provinces with the highest burden of disease attributed to low fruits intake were Tibet, Guizhou and Xinjiang provinces, with standardized DALY rate at 2 612.53/100 000, 2 281.85/100 000 and 2 198.22/100 000, respectively. Compared with the results in 1990, the standardized DALY attributed to low fruits intake decreased, especially in Tianjin, where decreased by 63.61%; followed by Aomen, Zhejiang, Shanghai and Beijing, where decreased by 59.74%, 59.53%, 56.64% and 53.88%, respectively.@*Conclusion@#Compared with the situation in 1990, the burden of disease attributable to low fruit intake decreased in 2013, but the situation is still serious, especially in Tibet, Guizhou and Xinjiang provinces, where the burden decreased comparatively slowly.
ABSTRACT
Objective@#To assess the disease burden attributable to household air pollution in 1990 and 2013 in China.@*Methods@#Based on data from the Global Burden of Disease Study 2013 in China (GBD 2013), we used population attributable fractions (PAF) to analyze the burden of different diseases attributable to solid-fuel household pollution in 2013 in China(not inclnding HongKang, Macao, Taiwan). We compared PAF, mortality, and disability-adjusted life years (DALY) for diseases attributable to solid-fuel household pollution in 31 provinces in mainland China in 1990 and 2013, and stratified the burden by age group. The estimated world average population during 2000- 2025 was used to calculate age-standardized mortality and DALY rates.@*Results@#In 2013, 14.9% of lower respiratory infections in children <5, 32.5% of chronic obstructive pulmonary disease (COPD), 12.0% of ischemic stroke, 14.2% of hemorrhagic stroke, 10.9% of ischemic heart disease, and 13.7% of lung cancer were attributable to solid-fuel household pollution. In addition, 807 000 deaths were attributable to solid-fuel household pollution, including 296 000 from COPD, 169 000 from hemorrhagic stroke, 152 000 from ischemic heart disease, 88 000 from ischemic stroke, 75 000 from lung cancer, and 28 000 from lower respiratory infections in children <5. The age-standardized mortality rate from solid-fuel household pollution decreased by 59.3% from 158.8/100 000 in 1990 to 64.6/100 000 in 2013. The age-standardized mortality rate from solid-fuel household pollution decreased in all 31 provinces, with the highest decline observed in Shanghai (96.3%), and lowest in Xinjiang (39.9%). In 2013, the age-standardized DALY rate from solid-fuel household pollution was highest in Guizhou (2 233.0/100 000) and lowest in Shanghai (27.0/100 000). The DALY rate was the highest for the >70 age group (7 006.0/100 000). Compared with 1990, the 2013 mortality rate and DALY rate from solid-fuel household pollution decreased in all age groups, with the highest decline observed in the <5 age group (91.9% and 91.8% , respectively).@*Conclusion@#Although the disease burden attributable to household air pollution decreased notably between 1990 and 2013, household pollution caused a high number of deaths and DALY loss in certain western provinces.

ABSTRACT
<p><b>OBJECTIVE</b>To analyze and compare burden of disease caused by malignant tumor in China, 1990 and 2010.</p><p><b>METHODS</b>The indicators including prevalence, death, years of life lost (YLL), years lived with disability (YLD), and disability adjusted of life years (DALY) of malignant tumor from the results of Global Burden of Disease (GBD) 2010 were used to calculate the standardized prevalence rate, mortality rate, YLL rate, YLD rate and DALY rate with the 2010 national census data. The research described the prevalence, death, and burden of disease caused by malignant tumor and analyze the trend of these indicators in 1990 and 2010 in China.</p><p><b>RESULTS</b>In China from 1990 to 2010, the standardized prevalence rate of malignant tumor increased from 529.76/100 000 to 749.57/100 000 (increased by 41.49%); the standardized mortality rate decreased from 196.57/100 000 to 169.88/100 000 (decreased by 13.58%); the standardized DALY rate decreased from 5 206.56/100 000 to 4 150.86/100 000. In 2010, the top five standardized DALY rate of malignant tumor were lung cancer, liver cancer, gastric cancer, esophageal cancer, and colorectal cancer. Their standardized DALY rate were 892.21/100 000, 787.40/100 000, 521.36/100 000, 303.95/100 000, and 269.94/100 000, respectively. In all kind of malignant tumors, the burden of disease of lung cancer had the fastest-growing rate. The standardized mortality rate of lung cancer increased from 34.78/100 000 in 1990 to 41.09/100 000 in 2010; the standardized DALY rate increased from 830.77/100 000 in 1990 to 892.21/100 000 in 2010. The burden of disease of gastric cancer had the fastest-falling rate. The standardized mortality rate of gastric cancer decreased from 39.65/100 000 in 1990 to 23.79/100 000 in 2010; the standardized DALY rate decreased from 968.96/100 000 in 1990 to 521.36/100 000 in 2010.</p><p><b>CONCLUSION</b>The burden of disease caused by malignant tumor in China remained at high levels in 2010. The top five burden of disease of malignant tumor were lung cancer, liver cancer, gastric cancer, esophageal cancer, and colorectal cancer. The burden of disease of lung cancer had the fastest-growing rate and gastric cancer had the fastest-falling rate from 1990 to 2010 in China. Prevention and control of malignant tumor was still difficult.</p>

<p><b>OBJECTIVE</b>To analyze the death status of disease burden of cardiovascular and circulatory diseases in 1990 and 2010 in China, and to provide the basic information for cardiovascular and circulatory disease prevention and control.</p><p><b>METHODS</b>Using the results of the Global Burden of Diseases Study 2010 (GBD 2010) to describe the cardiovascular and circulatory diseases deaths status and disease burden in China. The measurement index included the mortality, years of life lost due to premature mortality (YLL), years lived with disability (YLD), and disability-adjusted life years (DALY). At the same time, we used the population from 2010 national census as standard population to calculate the age-standardized mortality rate and DALY rate, YLL rate and YLD rates which will describe the mortality status and disease burden of total and different types of cardiovascular disease. We also calculated the change in 1990 and 2010 for all indexes, to describe the change of the burden of disease in the 20 years.</p><p><b>RESULTS</b>In 2010, the total deaths of cardiovascular and circulatory diseases reached 3.136 2 million, the mortality rate reached 233.70 per 100 000 people and the age-standardized mortality rate was 256.90 per 100 000 people. The total DALYs, YLLs, and YLDs of cardiovascular and circulatory diseases reached 58.2055, 54.0488, and 4.1568 million person-years, respectively, and the age-standardized DALY rate, YLL rate and YLD rate were 4 639.04, 4 313.13, 325.91 per 100 000. In 1990, the deaths only 2.1675 million and the DALYs, YLLs and YLDs were 45.2679, 42.2922, and 2.9757 million person-years. The age-standardized mortality rate was 300.30 per 100 000 people. And the age-standardized DALY rate, YLL rate and YLD rate were 5 872.58, 5 523.42 and 349.16 per 100 000. Compared with the result in 1990, the total deaths, DALYs, YLLs, and YLDs were increased 44.72%, 28.58%, 27.80%, and 39.68%, respectively, while the age-standardized mortality rate, age-standardized DALY rate, age-standardized YLL rate, and age-standardized YLD rate were decreased 14.45%, 21.01%, 21.91%, and 6.66%, respectively. In 1990 and 2010, cerebrovascular disease caused the most DALYs (24.8768 and 30.1389 million person-years, respectively) compared with other types of cardiovascular and circulatory diseases, and followed by ischemic heart disease (10.1270 and 17.8858 million person-years). And the YLLs of cerebrovascular disease (24.3436 and 29.1726 million person-years) also the highest in different type of cardiovascular and circulatory diseases, ischemic heart disease (8.9919 and 16.0839 million person-years) was the second highest. The deaths of cerebrovascular disease and cerebrovascular disease increased from 1 340.6 and 450.3 thousands in 1990 to 1 726.7 and 948.7 thousands in 2010, respectively. The age-standardized mortality rate and DALY rate of cerebrovascular disease were decreased from 187.19 and 3 335.37 per 100 000 people in 1990 to 141.43 and 2 409.09 per 100 000 people. While in the ischemic heart disease, the age-standardized mortality rate, and DALY rate were increased form 62.53 and 1 318.38 per 100 000 people in 1990 to 77.89 and 1 428.31 per 100 000 people.</p><p><b>CONCLUSION</b>Burden of cardiovascular and circulatory disease became more and more serious in China, of which the cerebrovascular disease and ischemic heart disease were most serious.</p>

<p><b>OBJECTIVE</b>To assess the burden of disease attributable to ambient particulate matter pollution in 1990 and 2010 in China.</p><p><b>METHODS</b>On the basis of the results of the Global Burden of Diseases Study 2010 (GBD 2010) for China's estimates, we used population attributable fractions (PAF) to examine the burden of disease (mortality and disability-adjusted life years (DALY)) attributable to ambient particulate matter pollution in 1990 and 2010 in China, with 95% uncertainty interval (95% UI) estimate, and increasing rate to explore the trends of attributed burden of disease across the study period of 20 years.</p><p><b>RESULTS</b>In 2010, 38.9% (95% UI: 27.0%-49.4%) of lower respiratory infections for < 5 years children, 27.2% (95% UI: 10.2%-37.5%) of lung cancer, 29.9% (95% UI: 25.8%-34.2%) of ischemic heart disease, 35.0% (95% UI: 27.4%-41.1%) of stroke, and 21.0% (95% UI: 10.7%-30.3%) of chronic obstructive pulmonary disease (COPD) for ≥ 25 years adults were attributable to ambient particulate matter pollution, which accounted for 1.235 (95% UI: 1.038-1.410) million deaths and 25.230 (95% UI: 21.770-28.600) million person years DALY in total, and increased by 33.4% and 4.0%, respectively by comparison with that in 1990 (0.926 million and 24.260 million person years). Lung cancer accounted for the largest increasing rate of 154.5% (from 0.055 million to 0.140 million) and 130.1% (from 1.330 million person years to 3.060 million person years), followed by ischemic heart disease (118.5%, from 0.130 million to 0.284 million, and 86.6%, from 3.280 million person years to 6.120 million person years) and stroke (41.0%, from 0.429 million to 0.605 million, and 33.8%, from 8.970 million person years to 12.000 million person years). The attributed mortality for both gender mostly occurred in age group of 60-79 years (male: 0.260 million and 0.404 million accounting for 53.7% and 54.8%; female: 0.214 million and 0.236 million accounting for 48.5% and 47.5%) both in 1990 and 2010. The age group of 40-79 years accounted for the most portion of attributed DALY for both gender (male: 8.458 million person years and 13.460 million person years accounting for 62.9% and 83.8%; female: 6.360 million person years and 7.152 million person years accounting for 58.9% and 78.0%). The increasing rates were higher for male than for female.</p><p><b>CONCLUSION</b>The burden of disease attributable to ambient particulate matter pollution was very high in China with significant increase in mortality and disability, which indicates the highly necessity for government to take actions to reduce ambient particulate matter pollution and its health hazards.</p>

<p><b>OBJECTIVE</b>To analyze the disease burden of chronic obstructive pulmonary disease (COPD) among people aged over 15 years in 1990 and 2010 in China.</p><p><b>METHODS</b>The estimation of China data for the Global Burden of Disease Study 2010 (GBD 2010) was used to analyze the mortality and prevalence as well as the years of life lost due to premature mortality (YLL), years lived with disability (YLD) and disability-adjusted life years (DALY) of COPD in China in 1990 and 2010 for Chinese people aged 15 years and above. The death rate and DALY rate of COPD in China in 1990 and 2010 were compared.</p><p><b>RESULTS</b>In 2010, 0.934 million people (0.534 million men and 0.400 million women) aged over 15 years died from COPD, decreased 34.5% (24.3% for men and 44.4% for women) compared with that in 1990 (1.425 million with 0.705 million men and 0.720 million women). There were 41.764 million COPD patients in 2010 (22.111 million men and 19.653 million women), increased 42.1% (41.7% for men and 42.6% for women) compared with 1990 (29.382 million patients with 15.599 million men and 13.783 million women). The mortality rate of COPD decreased for 61.5% from 2.352/100 000 in 1990 to 90.5/100 000 in 2010. The prevalence rate of COPD was 4.2% and 3.9% in 1990 and 2010, respectively. The DALY, YLL and YLD due to COPD was 16.598, 12.946, and 3.652 million person years, respectively in 2010. The YLD increased 42.3% compared with 1990 (2.567 million person years). From 1990 to 2010, the age-standardized DALY rate, YLL rate and YLD rate decreased from 4 120.1/100 000 to 1 575.9/100 000, from 3 756.9/100 000 to 1 235.6/100 000 and from 363.2/100 000 to 340.3/100 000, respectively.</p><p><b>CONCLUSION</b>Although there was significant decrease of DALY due to COPD in 2010, compared to 1990, the YLD burden is still increasing.</p>
