Global burden of disease attributable to high systolic blood pressure in older adults, 1990-2019: an analysis for the Global Burden of Disease Study 2019

Aims: High systolic blood pressure (HSBP), a significant public health challenge, has not been systematically studied in the elderly population in the context of global aging. Understanding the temporal trends of the disease burden associated with HSBP in the elderly population is essential to control and mitigate the harm caused by HSBP.

Methods and results: We used the estimated data derived from the Global Burden of Disease Study to analyse the disease burden of HSBP among the elderly population by region, sex, and temporal changes from 1990 to 2019. We found that the number of deaths due to HSBP increased to 7.86 (95% UI: 6.89-8.82) million, with an increase of 54.1%, and the number of disability-adjusted life years (DALYs) increased to 146 (95% UI: 130-162) million, with an increase of 52.4%. Conversely, the death and DALY rates of HSBP decreased by -27.0 and -27.8%, respectively. At the national and regional levels, Australasia and other high socio-demographic index regions have made significant improvements in the burden of HSBP, while it remains high in other regions of the world. Additionally, the burden of HSBP in older men is greater than that in older women.

Conclusion: Our findings indicate that the current prevention and control of HSBP in older adults is poor, with the total burden increasing significantly. There is an urgent need to implement feasible measures to resist HSBP and lessen the disparity of the global HSBP burden for older adults.
