Abstract:
Objective To analyze the attributable burden of disease and changes of risk factors in the elderly population aged 60 and over in different genders and provinces in China, so as to help the etiological prevention of the elderly population.
Methods Using GBD 2019 burden of disease data of risk factors for the elderly aged 60 and over in China, the effects and changes of different risk factors on health and life expectancy of the elderly by province and sex in China from 2009 to 2019 were evaluated with attribution disability-adjusted life years(DALY) as the index, and the standardized rate was calculated with the population aged 60 years old and over in the sixth population census in 2010 as the standard population.
Results In 2019, the total number of risk factors led to the DALY of the elderly aged 60 and over in China reached 114.5179 million person years, accounting for 60.19% of the total DALY of the elderly population. The main risk factors affecting the health of the elderly in China include tobacco, high systolic blood pressure, dietary factors, air pollution, high fasting blood glucose, high body mass index, high LDL-C, kidney dysfunction, non-optimal temperature and drinking alcohol. The main risk factor affecting the health of elderly men is tobacco, while elderly women have high systolic blood pressure. In 2019, dietary factors, high body mass index, kidney dysfunction, and drinking alcohol all increased in the order of DALY, while air pollution, high LDL-C and non-optimal temperature decreased in the order of DALY. Compared with 2009, the attributable DALY standardized rate of the elderly aged 60 and over in all provinces of China decreased in 2019. The five provinces with the largest decline were Fujian (27.00%), Guangdong (25.70%), Tianjin (24.24%), Zhejiang (22.96%) and Beijing (21.47%).
Conclusion From 2009 to 2019, the attributable disease burden of the elderly aged 60 and over in China increased. In order to achieve the goal of healthy aging, we should actively carry out etiological prevention through the implementation of effective policies and measures, such as health education, improving living environment and providing health management services, so as to reduce the disease burden caused by tobacco, drinking alcohol, dietary factors, air pollution, high body mass index and non-optimal temperature.
