Disease burden of dementia attributed to high BMI in 1990–2019 / 公共卫生与预防医学

ABSTRACT

Objective To understand the changing trend of dementia disease burden attributed to high BMI in China from 1990-2019, and to provide a basis for the development of dementia prevention and control strategies. Methods Using data from the Global Burden of Disease Study 2019(GBD2019)，the changes in disease burden were analyzed using indicators such as deaths, disability adjusted life years (DALYs), years lived with disability (YLDs), years of life lost (YLLs) and their standardized rates. The differences between sexes and age groups were compared. Joinpoint regression model was used to analyze the trend of changes in the disease burden of dementia attributable to high BMI in China. Results From 1990 to 2019, the burden of dementia disease attributed to high BMI continued to increase, with 20,300 more deaths, 404,200 more DALYs, and more than a four-fold increase in both mortality and DALYs rates. The overall burden of disease was greater for women than for men, but the rate of increase in the burden of disease was higher for men than for women. The disease burden in the age group of 80 and over was significantly higher than in other age groups. Conclusion Attention should be paid to people with high BMI, especially for the prevention and control of dementia risk in older age groups with high BMI. Active countermeasures should be taken to control the occurrence of dementia.
