Abstract:
Objective To analyze the burden of disease caused by disability and its changes in the population aged 60 years or older in China based on the data of Global Burden of Disease Study 2019 (GBD 2019).
Methods By using the GBD 2019 data on years lived with disability (YLD) in the population aged 60 years or above in China as the index, the burden of disease caused by disability and its changes in the elderly population in China from 2009 to 2019 were analyzed, and the standardized calculation of the rate was performed using the data of the population aged 60 years or above in the sixth population census in 2010.
Results In 2019, the YLD of the population aged 60 years or above in China reached 56.371 million person years, and the top 6 diseases ranked by YLD were age-related and other hearing loss (hereinafter referred to as "hearing loss"), stroke, low back pain, chronic obstructive pulmonary disease (COPD), blindness and vision loss, and diabetes mellitus, with YLD of 5.587, 4.289, 3.706, 3.224, 3.097, and 3.087 million person years, respectively. The standardization rates of YLD were 2 181.9/100 000, 1 680.3/100 000, 1 443.3/100 000, 1 265.0/100 000, 1 210.0/100 000, and 1 199.3/100 000, respectively. In 2019, the YLD for males and females aged 60 years or above was 24.549 and 31.821 million person years, respectively. Among males and females aged 60 years or older, the standardized rate of YLD was decreased for five diseases (diabetes mellitus, COPD, blindness and vision loss, low back pain, and hearing loss)in the top 16 diseases ranked by YLD, with the largest decreases in COPD in males and diabetes mellitus in females, which the change rate of YLD standardized rate of was 18.6% and 15.2%, respectively. Over the 10-year period, falls, road injuries (mainly in males), stroke, Alzheimer's disease and other dement had the largest increases in YLD and YLD standardized rates.
Conclusion From 2009 to 2019, China has made some progress in the prevention and treatment of hearing loss, low back pain, COPD, blindness and vision loss, and diabetes mellitus among the population aged 60 years or above, but the overall burden of YLD still showed an increasing trend. In the future, attention should continue to be paid to diseases with high standardized rates of YLD, such as hearing loss, stroke, low back pain, COPD, blindness and vision loss, and diabetes mellitus. At the same time, falls, road injuries, stroke, Alzheimer's disease and other dement with a large increase in the standardized rate of YLD should not be ignored, and measures should be taken for prevention and control.
