To assess the burden of stroke and its subtypes attributable to dietary factors in China from 1990 to 2021.
Utilizing the Global Burden of Disease (GBD) 2021 database, we analyzed the trends of stroke and its subtypes (ischemic stroke, hemorrhagic stroke, subarachnoid hemorrhage) caused by dietary factors in China using the Join point regression model and estimated annual percentage change (EAPC).
In 2021, the number of stroke deaths attributable to dietary factors in China was 1 077 762, with an age-standardized mortality rate (ASMR) of 21.59 per 100 000. From 1990 to 2021, both the ASMR and age-standardized disability-adjusted life years (DALYs) rate (ASDR) due to dietary factors showed a declining trend, with EAPCs of -2.69 and -2.74, respectively. Ischemic stroke presented the heaviest burden, with an ASMR of 11 per 100 000. Excess sodium intake was identified as the primary dietary risk factor, with an ASMR of 8.77 per 100 000 for ischemic stroke attributable to excess sodium and an ASMR of 10.6 per 100 000 for hemorrhagic stroke. The burden of disease was significantly higher in males and individuals aged 70 and above, with mortality rates more than twice that of other age groups.
Over the past 32 years, the burden of stroke attributable to dietary factors in China has decreased, yet the overall numbers remain substantial.Future public health policies should focus on controlling high-sodium diets and increasing the intake of grains and fruits, particularly targeting high-risk populations such as elderly males, to further reduce the burden of stroke.
