RESUMEN
As the life expectancy of the population increases and traditional indexes are flawed in reflecting the health level, the concept of the healthy life expectancy has emerged, which integrates the length of the life and quality, more comprehensively reflects the health level of the population. This article has summarized the emergence and development of health life expectancy, classification of indexes, and commonly used measurement methods, as well as domestic and international application examples, and domestic research status. It proposes to establish a unified national measurement method, and make full use of big data resources in health care to comprehensively assess the health life expectancy of the population.
RESUMEN
Objective To analyze the death characteristics and disease burden of the labor force in Jingzhou City from 2015 to 2018, and to provide a basis for formulating policies to protect the labor force population and propose effective prevention and control measures to reduce the death level and disease burden. Methods The death data of the labor force in Jingzhou City from 2015 to 2018 was collected and statistically analyzed. The death levels, causes of death, and disease burden of the labor force in different years, sexes, ages, and regions were analyzed. Results From 2015 to 2018, the death toll of the labor force accounted for 24.79% of total deaths in Jingzhou City, with a mortality rate of 219.61/100 000 and a standardized mortality rate of 192.17/100 000. There was no significant difference in the mortality rate in different years (P=0.34). The male and female mortality rates were 297.77/100 000 and 139.63/100 000, and the standardized mortality rates were 257.36/100 000 and 119.57/100 000, respectively. The male and female YLL rates were 9.55% and 4.47%, and the standardized YLL rates were 6.75% and 3.12%, respectively. The male mortality and YLL rates were higher than those of the female (P<0.01). The mortality and YLL rate of different age groups increased with age (P<0.01). The mortality rates of urban and rural population were 187.37/100 000 and 229.07/100 000, respectively, the standardized mortality rates were 141.87/100 000 and 208.58/100 000, respectively, the YLL rates were 5.90% and 7.37% respectively, and the standardized YLL rates were 4.13% and 5.20%, respectively. The mortality rate and YLL rate of rural population were higher than those of urban population (P<0.01). The first cause of death in the labor force population was malignant tumor, with the mortality and YLL rate being 87.19/100 000 and 2.90%, respectively. The second cause was injury, with the mortality and YLL rate of 42.60/100 000 and 1.56%, respectively. The leading cause of death was injury in the 15 and 25 years old groups, and malignant tumor in the 35, 45 and 55 years old groups. Lung cancer and liver cancer were the main types of lethal cancers. Transportation accidents and suicide were the main types of lethal injuries. Conclusion The disease burden of the rural labor force was heavy. It is important to strengthen health education for the rural labor force, especially male laborers over the age of 45, and to implement early cancer diagnosis and treatment and injury intervention programs to effectively improve the health of the labor population.
RESUMEN
With the continuous development of society and economic activities, ambient air pollution has become an important global environmental and public health issue, and its significant adverse effects on human health have attracted increasing attention. Previous studies have shown a significant association between air pollution exposure and cardiovascular events including cardiac arrest. Although the association between air pollution exposure and risk of cardiac arrest has been identified by several studies, the results remain inconsistent and the pathogenic mechanism is not yet clear. To date, most studies focused on the impact of air pollution exposure on the onset of cardiac arrest, while few studies explored the risk of death from cardiac arrest. Here we reviewed studies investigating the association between short-term exposure to air pollution and risk of cardiac arrest.
