What is the global burden and temporal trend of cardiovascular disease attributable to high BMI among young adults aged 20-39 years from 1990 to 2021?
High BMI significantly contributes to the global burden of cardiovascular disease in young adults, particularly ischemic heart disease, with increasing trends in low-to-middle income regions highlighting the need for targeted prevention.
Background: Understanding temporal trends in the burden of cardiovascular disease (CVD) attributable to high body mass index (BMI) in young adults is important for effective and targeted prevention strategies and measures. We aimed to provide comprehensive estimates of CVD deaths and disability-adjusted life-years (DALYs) rate attributable to high BMI in young adults aged 20-39 years at the global, regional, and national levels, as well as temporal trends from 1990 to 2021. Methods: We calculated age-standardized deaths rate and DALYs rate as well as estimated annual percentage changes (EAPC) using Global Burden of Disease (GBD) 2021 study data on deaths and DALYs for CVD attributable to high BMI among young adults aged 20-39 years. Results: Among non-communicable diseases, the burden of cardiovascular disease attributed to high BMI among young adults aged 20-39 years is much higher than chronic respiratory diseases, diabetes and kidney diseases, digestive diseases, and neoplasms. Among specific types of cardiovascular disease, ischemic heart disease accounted for the highest proportion, while stroke had the largest increase in the rate of DALYs. an increase in age-standardized DALYs rate over time in low-to-middle SDI regions, a decrease in age-standardized DALYs rate over time in high SDI regions, and a decrease in health inequality in 2021 compared with 1990. Conclusion: In 2021, the high burden of cardiovascular disease attributed to high BMI among young adults varied by region, country, gender, and Socio-demographic index (SDI). The greater burden of cardiovascular disease among young adults in low - and middle-income countries may be linked to unhealthy diets, health awareness, and lifestyles among young adults in low - and middle-income countries. Given the potential for improvement in high BMI, initiatives targeting this risk factor could significantly reduce the burden of CVD. Thus, prioritizing cost-effective policies and interventions is urgently needed.
