Burden of ischemic stroke in sub-Saharan African countries based on DALYs index - trend analysis and identification...

Stroke burden, measured by DALYs, reveals a growing concern in sub-Saharan Africa. Ischemic stroke, exacerbated by modifiable risk factors like hypertension and household air pollution, poses a significant health challenge. Regional disparities, economic development, and healthcare inefficiencies underscore the need for targeted interventions and further research.

This study aims to analyze trends in the burden of ischemic stroke across specific regions in sub-Saharan Africa from 2000 to 2019. The objective is to identify key changes in stroke burden progression and highlight modifiable risk factors.

Utilizing World Health Organization (WHO) data from 2000 and 2019, national estimates of ischemic stroke DALYs in 49 sub-Saharan African countries were collected. DALYs were calculated per 100,000 population to reduce the impact of population size. Statistical analyses and visual representations using MapChart were employed to interpret the trends.

The study reveals wide variations in ischemic stroke DALYs changes across sub-Saharan African countries from 2000 to 2019. Predominantly, countries in the Eastern and Southern regions experienced adverse increases, while those in the Central and West regions mostly exhibited declines in DALYs. Countries such as Lesotho, Zimbabwe, and Mauritius, saw the most significant DALYs increases, whereas Rwanda, Malawi, and Equatorial Guinea experienced the most favorable changes.

Stroke is a pressing health concern in sub-Saharan Africa. Modifiable risk factors like hypertension and household air pollution necessitate targeted interventions. Tailored healthcare policies, reinforced health systems and comprehensive research into region-specific risk factors are crucial to alleviate stroke-related morbidity and mortality in the region. Addressing these challenges is vital to mitigate the increasing burden of stroke in the particular regions of sub-Saharan Africa.
