Reinforces what was already believed, rather than introducing something new.
This cross-sectional epidemiological analysis of Global Burden of Diseases 2021 data reports that in 2021, childhood leukemia accounted for 58,785 incident cases, 27,861 deaths, and 2.34 million DALYs globally, with an incidence rate of 4.37 per 100,000. Global incidence and death rates declined modestly from 1990 to 2021 (−0.23% and −0.52% respectively), but low-sociodemographic-index regions showed rising trends, revealing persistent disparities in disease burden and outcomes across geographic and economic strata.
Cross-sectional epidemiological analysis. Children aged 0 to 14 years across all 204 countries and territories included in the Global Burden of Diseases 2021 database. 204 countries and territories globally.
In 2021, childhood leukemia caused 58,785 incident cases (95% UI 43,200–73,139) and an incidence rate of 4.37 per 100,000 (95% UI 3.51–5.46) Global incidence rate declined by 0.23% (95% UI −0.44% to −0.11%) and death rate by 0.52% (95% UI −0.64% to −0.35%) from 1990 to 2021 Low-SDI region exhibited rising incidence, mortality, and DALY rates
Source does not provide confidence intervals for all reported mortality and DALY figures (e.g., Tokelau) Low-SDI region exhibited rising incidence, mortality, and DALY rates
Clinicians and public health professionals should recognize persistent global disparities in childhood leukemia burden, particularly in low-resource settings where incidence, mortality, and DALY rates are rising despite global reductions. This epidemiological assessment underscores the need for context-specific prevention, diagnostic, and treatment strategies to address inequities.
A large descriptive epidemiological analysis confirming known patterns of childhood leukemia burden globally, with stratified trend data reinforcing established disparities between high- and low-resource settings, but not providing clinical intervention evidence.

Childhood leukemia remains a critical global public health challenge, contributing significantly to disability and premature mortality. Despite progress in healthcare, comprehensive estimates of its burden across geographic and sociodemographic strata remain essential for formulating evidence-based interventions. Utilizing data from the Global Burden of Diseases 2021, this cross-sectional study analyzed leukemia incidence, deaths, and disability-adjusted life years (DALYs) among children aged 0 to 14 across 204 countries and territories from 1990 to 2021. Stratified analyses by region, nation, age, sex, leukemia type, and Sociodemographic Index (SDI) were conducted, with estimated annual percentage changes calculated to assess trends. In 2021, childhood leukemia caused 58,785 incident cases (95% uncertainty interval [UI], 43,200-73,139), 27,861 deaths, and 2,341,610 DALYs globally, corresponding to an incidence rate of 4.37 per 100,000 (95% UI, 3.51-5.46). From 1990 to 2021, global incidence and death rates declined by a total of 0.23% (95% UI, -0.44% to -0.11%) and 0.52% (95% UI, -0.64% to -0.35%), respectively. However, the low-SDI region exhibited rising incidence, mortality, and DALY rates. Australasia experienced the largest incidence increase (estimated annual percentage change: 0.67%, 95% confidence interval, 0.23%-1.11%). Nationally, San Marino reported the highest incidence (13.79 per 100,000; 95% UI, 8.03-21.07), while Tokelau had the highest mortality (7.92 per 100,000; 95% UI, 4.36-13.32) and DALY rates (116.39 per 100,000; 95% UI, 86.46-139.97). Despite global reductions in childhood leukemia burden over 3 decades, persistent disparities across SDI subgroups and regions underscore unmet needs in low-resource settings. Precision epidemiology and context-specific strategies are imperative to mitigate inequities and optimize prevention and care.
