To analyze the changing trend of disease burden of senile dementia attributed to high BMI in China from 1990 to 2019, and to provide references for the formulation of prevention and control strategies for senile dementia in China.
The data of death number, mortality rate, disability adjusted life years (DALY) number and DALY rate of senile dementia attributed to high BMI in China from 1990 to 2019 were extracted from the global disease burden database, and the estimated annual percentage of change (EAPC) was used to analyze the change trend in terms of sex, age and exposure rate.
From 1990 to 2019, the disease burden of senile dementia attributed to high BMI in China showed an upward trend. The burden of women was higher than that of men, and the latter had the fatest increase. The mortality rate and DALY rate increased with the increase of age, with the fastest increase in males aged 60 to 70 years and females aged 60 to 75 years, respectively.Males had larger EAPC than females in the same age group. From 1990 to 2019, the DALY loss of senile dementia caused by high BMI had the fatest increase, and the standardized (summary exposure value) SEV rate of high BMI increased rapidly (EAPC=3.67%, P < 0.001).
From 1990 to 2019, the burden of senile dementia attributed to high BMI in China became heavier. With the increase of aging and obesity rate, the burden of senile dementia attributed to high BMI is expected to continue to increase rapidly without no sustained and effective intervention.
