Research has been conducted on the global trends and inequalities in stroke and its subtypes, with a focus on the impact of high body mass index. The studies appear to cover various aspects of stroke epidemiology, including risk factors, predictive insights, and health inequalities, as well as the relationship between body mass index and stroke risk. The scope of the research spans multiple regions and demographics, including pediatric and older adult populations, and incorporates data from 1990 to 2021.
