NAFLD has emerged as a major cause of chronic liver disease globally, with Asia and MENA regions bearing a substantial burden of LC-NAFLD. Dietary risks, metabolic risks, and physical inactivity are positively correlated with DALYs related to NAFLD in these regions.
Background & Aim: Non-alcoholic fatty liver disease (NAFLD) has become a major cause of chronic liver disease (CLD) worldwide. Our aim was to assess the burden of liver complications (LC, cirrhosis and liver cancer) related to NAFLD (LC-NAFLD) between 2009-2019 in Asia and the Middle East and North Africa (MENA) region. Methods: We used Global Burden of Disease data to assess incidence, mortality, and disability-adjusted life years (DALYs) for LC-NAFLD from Asia and the MENA region. Annual % change (APC) in rates were computed using a joinpoint regression model. Associations of LC-NAFLD with low physical activity, diet and metabolic risks were determined by partial Spearman correlation coefficients (rho). Results: Globally in 2019, there were 170,000 incident cases of LC-NAFLD, accounting for 6.6% of LC incident cases from all CLDs. There were 168,969 deaths related to LC-NAFLD, accounting for 8.6% of LC deaths from all CLDs. Asia accounted for 48.3% of the global incidence of LC-NAFLD and for 46.2% of deaths attributable to LC-NAFLD, while MENA accounted for 8.9% and 8.6%, respectively. There were 2.08 million DALYs in Asia and 340,000 DALYs in MENA. From 2009 to 2019, regions in Asia and MENA experienced a rise in DALYs attributable to LC-NAFLD (compared to LC from other CLDs), ranging from South Asia (APC = +2.12% vs. 0.94%) to high-income Asia Pacific (APC = -0.07%, p = 0.646 vs. 0.97%). In Asia, NAFLD-related DALYs were significantly correlated with dietary risks (95% CI 0.280-0.763, p = 0.004), metabolic risks (0.341-0.790, p <0.001) and tobacco use (0.134-0.691, p = 0.007). In MENA, low physical activity (0.557-0.918, p <0.001), metabolic risks (0.432-0.888, p = 0.001), and dietary risks (0.315-0.855, p = 0.001) correlated with DALYs. Conclusions: NAFLD is posing a substantial burden in Asia and MENA. About half of the global burden of LC-NAFLD is accounted for by these regions. Lay summary: Non-alcoholic fatty liver disease (NAFLD) has emerged as one of the most common causes of chronic liver disease worldwide. We used Global Burden of Disease data to assess the incidence, mortality, and disability-adjusted life years attributable to NAFLD-related liver complications in Asia, the Middle East and North Africa. NAFLD is poised to contribute to a substantial liver disease burden in these regions. Regional and global policies are needed to address the increasing burden of complications of NAFLD.
