ABSTRACT Background Methods Results Conclusion Metabolic dysfunction‐associated steatotic liver disease is a significant driver of the increasing global burden of chronic liver disease. This study aimed to describe the temporal trends and inequalities of liver complications related to metabolic dysfunction‐associated steatotic liver disease (LC‐MASLD) by geographical region, age and sex during 1990–2021.Global Burden of Diseases Study 2021 data were analysed to assess LC‐MASLD incidence, prevalence, mortality and disability‐adjusted life years (DALYs). Temporal trends during 1990–2021 were measured by ‘estimated annual percentage change’ (EAPC). Inequalities of LC‐MASLD burden across countries were evaluated by the slope index of inequality (SII) and the relative concentration index (RCI).During 1990–2021, LC‐MASLD rose annually by 0.73% in incidence and prevalence, 0.19% in mortality and 0.16% in DALYs. In 2021, the Middle East and North Africa had the highest incidence and prevalence and Andean and Central Latin America had the highest mortality and DALY rates. While LC‐MASLD incidence was earliest in the 15–19 age group, both prevalence and DALY rates peaked at 75–79 years for both sexes. Inequalities in mortality and DALYs by countries' socioeconomic development index increased during 1990–2021, demonstrated by a decline in SII from −0.09 to −0.56 per 100 000 for mortality and from 1.41 to −7.74 per 100 000 for DALYs. RCI demonstrated similar findings.The LC‐MASLD burden is increasing globally, especially in economically disadvantaged countries, with widening disease inequalities during 1990–2021. Effective prevention and subregional interventions are crucial, with a specific focus on resource optimisation for disadvantaged populations. [ABSTRACT FROM AUTHOR]

Background: Diarrhea remains a significant health threat to children under five years of age. The study aims to systematically elucidate the global burden of diarrhea in children, providing scientific insights for effective prevention and control strategies. Methods: The data from the Global Burden of Disease (GBD) 2021 study was analyzed to assess the trends in incidence, prevalence, mortality, and disability-adjusted life years (DALYs) of diarrhea in children under five years across the globe, 21 geographical region, and 204 countries and territories, stratified by age group, sex, and socio-demographic index (SDI) levels. The trend of the disease burden for childhood diarrhea from 1990 to 2021 was described and estimated using the average annual percent change (AAPC), and a Bayesian age-period-cohort (BAPC) model was employed to predict the future burden of diarrhea in children. Results: From 1990 to 2021, there was a significant decline in the global burden of diarrhea among children under five years of age. The AAPC for incidence (−4092.18, 95% confidence interval [CI]: −4224.60 to −3959.76), prevalence (−70.98, 95% CI: −72.67 to −69.28), mortality (−6.89, 95% CI: −6.95 to −6.83), and DALYs rate (−621.79, 95% CI: −627.20 to −616.38) of diarrhea in children all showed a marked downward trend.
