This study provides the first comprehensive estimated global burden of neonatal disorders attributable to risk factors in 1990–2021 stratified by sex, cause, sociodemographic index (SDI), and region. We identified persistent disparities across SDI levels, with low birthweight and short gestation contributing most to the age-standardized disability-adjusted life year rate of neonatal disorders. These findings highlight the urgent need for targeted context-specific interventions to reduce infant mortality and improve neonatal health equity. |
