To evaluate long-term trends in disability, mortality, and prevalence of G6PD deficiency globally.
Conducted ecological cross-sectional analysis using Global Burden of Disease data from 1990 to 2021
Extracted estimates of disability-adjusted life years, years of life lost, and prevalence for each country
Ranked countries by G6PD-related burden in 2021
Select top five countries for longitudinal analysis.
China had the highest G6PD-related DALY burden (53,047.5) in 2021, with a 12.7% decline since 1990
India's DALYs increased by 75.4%, while Nigeria's nearly doubled at +98.9%
Prevalence rose in all five countries, with China reporting 66.1 million cases (+64.4%)
YLLs increased in India (+95.3%) and Nigeria (+58.5%), while decreasing in China (−12.2%) and Indonesia (−4.5%)
