ABSTRACT

Objective To analyze the disease burden of falls in Chinese population aged 70 and over,in 1990 and 2013 and to provide evidence for the development of prevention strategies on falls in the elderly.Methods Indicators including mortality rate,years of life lost due to premature mortality (YLL),years lived with disability (YLD) and disability-adjusted of life years (DALY) on falls,were gathered from the results of Global Burden of Disease 2013 and used to describe the disease burden of falls in China by calculating the changing rates on corresponding parameters in 1990 and 2013.Results In 2013,the number of deaths,YLLs,YLDs,DALYs caused by falls among Chinese population aged 70 and over were 48 800,0.44 million person years,0.30 millions person years,and 0.74 million person years,respectively.The standardized mortality rate,rates on YLLs,YLDs and DALYs of falls were 561.71 per 100 000,55.87 per 100 000,373.98 per 100 000 and 929.85 per 100 000,respectively.The burden of falls increased along with the increase of age.Compared with 1990,the number of deaths,YLLs,YLDs and DALYs caused by falls increased by 308.80％,161.01％,54.67％ and 104.47％,respectively,in 2013,more seen in males than in females.The standardized mortality rate,YLLs and DALYs caused by falls increased by 63.67％,38.54％ and 73.08％,respectively,during 1990 and 2013.However,the standardized YLDs rate fell by 17.90％ during the same period.Conclusion Falls caused heavy disease burden which increased in 1990 and 2013 among the Chinese population aged 70 and over.
