Global Burden of Diet High in Processed Meat-related Stroke, 1990-2021.

Introduction: This study aimed to analyze the global, regional, and national burden and trends of stroke related to high consumption of processed meat from 1990 to 2021, using data from the Global Burden of Disease (GBD) Study 2021.

Methods: An observational trend analysis was conducted using data from the GBD Study 2021. Age-standardized rates for deaths and disability-adjusted life years (DALYs) were calculated using the world standard population. Estimated annual percentage change (EAPC) was assessed using linear regression models.

Results: From 1990 to 2021, the global age-standardized death rate due to diet high processed meat-related stroke decreased from 0.80 per 100,000 (95% UI: 0.18 to 1.43) to 0.27 per 100,000 (95% UI: 0.06 to 0.46), with an EAPC of -4.23% (95% UI: -4.54 to -3.92). The age-standardized DALY rate also declined from 14.16 per 100,000 (95% UI: 3.19 to 25.49) to 5.20 per 100,000 (95% UI: 1.21 to 9.33), with an EAPC of -4.00% (95% UI: -4.34 to -3.67). Significant disparities were observed across regions and socioeconomic strata, with higher burdens in high-middle SDI regions. Females consistently had higher death and DALY rates and counts than males.

Discussion: The study reveals a significant decline in both mortality and DALYs associated with a diet high in processed meat-related stroke over the three decades.

Conclusion: Our study highlighted the effectiveness of public health interventions. However, disparities persist across regions and socioeconomic strata, emphasizing the need for targeted and context-specific strategies to mitigate the burden of stroke related to high processed meat intake.
