Comparative analysis of comprehensive health status among 31 provinces in China and 134 countries (regions) in 2015 / 中华预防医学杂志

To evaluate comprehensive health status of 31 provinces in China and compare with other countries (regions). Social-demographic index, life expectancy and healthy life expectancy in 134 countries (regions) and 31 provinces in China were collected from the Global Burden of Disease Study 2015. -means clustering method was used to classify comprehensive health status of various countries (regions) in the world. HemI 1.0.3 software was applied to draw distribution heat maps of social-demographic index, life expectancy and healthy life expectancy in different provinces of Mainland China. Discriminant analysis was used to evaluate comprehensive health status of different provinces in Mainland China. Comprehensive health status of 134 countries (regions) was grouped into category 1-8 from good to poor, and Mainland China was in the category 4. The comprehensive health status of provinces in Mainland China is better in the east coast and poorer in the west inland, among which Shanghai and Beijing were grouped into the category 1, Zhejiang, Jiangsu, Guangdong and Tianjin into the category 2, Fujian, Liaoning and Shandong into the category 3, Yunnan, Guangxi, Xinjiang and Guizhou into the category 5, Qinghai and Tibet into the category 6, and the rest 16 provinces into the category 4. Comprehensive health status of Mainland China ranked middle to upper level in the world, and health status disparities were observed among different provinces in Mainland China.

Decomposition of life expectancy among permanent residents of Beijing, 2000-2010 / 中华流行病学杂志

Objective To analyze the change of life expectancy and the impact of mortality by age and causes of death on this issue among permanent residents of Beijing.Methods Abridged Life Table and Arriaga method were used to calculate and to decompose the changes on life expectancy by age and causes of death in 2000-2010.Results From 2000-2010,life expectancy under this studied population had an increase of 3.35 years.Most part of the increases (44.27％,1.48 years) within the last 10 years could be explained by the decrease of mortality in the population at age ≥ 80.Both cerebrovascular and heart diseases were contributing the most to the increment of life expectancy while mortality of malignant tumors appeared a negative contributor to this increment.Conclusion From 2000 to 2010,increment in life expectancy contributed to the decrease of mortality in the elderly and the decrease of mortalities on both cardio-and cerebro-vascular diseases.The decrease of life expectancy was mainly due to the increase of mortality related to malignant tumors.

Assessing heat-related mortality risks in Beijing, China / 生物医学与环境科学（英文）

<p><b>OBJECTIVE</b>To obtain the exposure-response relationship for temperature and mortality, and assess the risk of heat-related premature death.</p><p><b>METHODS</b>A statistical model was developed using a Poisson generalized linear regression model with Beijing mortality and temperature data from October 1st, 2006 to September 30th, 2008. We calculated the exposure-response relationship for temperature and mortality in the central city, and inner suburban and outer suburban regions. Based on this relationship, a health risk model was used to assess the risk of heat-related premature death in the summer (June to August) of 2009.</p><p><b>RESULTS</b>The population in the outer suburbs had the highest temperature-related mortality risk. People in the central city had a mid-range risk, while people in the inner suburbs had the lowest risk. Risk assessment predicted that the number of heat-related premature deaths in the summer of 2009 was 1581. The city areas of Chaoyang and Haidian districts had the highest number of premature deaths. The number of premature deaths in the southern areas of Beijing (Fangshan, Fengtai, Daxing, and Tongzhou districts) was in the mid-range.</p><p><b>CONCLUSION</b>Ambient temperature significantly affects human mortality in Beijing. People in the city and outer suburban area have a higher temperature-related mortality risk than people in the inner suburban area. This may be explained by a temperature-related vulnerability.</p>
