Burden of renal anemia in 204 countries and territories, 1990-2021 : results from the Global Burden of Disease Study 2021

Abstract

AbstractRenal anemia has inflicted a certain degree of loss on global health. However, there are no systematically analyses on the burden of renal anemia.We analyzed global prevalence and years lived with disability (YLDs) of renal anemia from 1990 to 2021. Based on the Socio-Demographic Index (SDI), combined with cross-national inequality analysis, frontier analysis and age-period-cohort (APC) model analysis, the prevalence and YLDs differences between different aspects were compared.Since 1990, the prevalence and YLDs of renal anemia in 2021 have shown an upward trend. In countries with medium and low levels of development, the burden of renal anemia is particularly severe among people over 60 years. A series of analyses based on the SDI revealed a negative correlation between the prevalence of renal anemia and SDI.Thus, Public health policies targeting renal anemia should give priority to the elderly in medium- and low-development areas.
