Abstract
Objective: Analyzing the association between low-fiber diet and cardiovascular diseases (CVD) using the 1990-2019 Global Burden of Disease (GBD) database, this study also examines trends in health inequality.
Methods: The 2019 GBD data, including DALYs and ASDR related to CVD from low-fiber diets, were utilized. Disease mapping visualized global, regional, and national burdens, while measures like SII and CI assessed inequality.
Results: The burden of CVD from low-fiber diets slightly increased from 1990 to 2019, with higher DALY numbers in males. India, China, and Indonesia had the highest DALY numbers in 2019. Southeast Asia had the highest advantage in DALY rates and ASDR for CVD attributed to a low-fiber diet among all regions globally, with 431.2 (95% UI: 250.7 - 612.1) and 453.6 (95% UI: 263.9 - 640.1) respectively. Low SDI countries had lower ASDR, while high SDI countries controlled their ASDR. Inequality decreased between low-income and high-income countries in CVD burden.
Conclusion: Low-fiber diet is associated with CVD, showing regional and gender differences. International health inequality related to this burden is gradually reducing. Findings support the development of targeted strategies for preventing and intervening in CVD, improving global cardiovascular health, and reducing health inequality.
