Abstract

Children are the main susceptible group to acute lymphoblastic leukemia (ALL), and the lack of sufficient data has impeded a comprehensive understanding of its global impact. This study analyzed the annual numbers and rates of incidence, deaths, and disability-adjusted life years (DALYs) of childhood ALL from 1990 to 2021, disaggregated by age group, gender, and socio-demographic index (SDI) at the global, regional, and national levels, based on the 2021 Global Burden of Disease (GBD) database. Although global deaths and DALYs rates for childhood ALL showed declining trends, the incidence rate fluctuated. Incidence rates in high SDI regions were higher, but deaths and DALY rates were lower. Moreover, the burden in Sub-Saharan Africa and other low SDI countries was growing. The burden on boys has been higher than on girls in this period. This study underscored improving prevention and treatment measures are critical to control the persistent global burden of children ALL.
