With this study, we aimed to estimate the disease burden attributable to child and maternal malnutrition (CMM) throughout the world between 1990 and 2019. The number, age-standardized rate, population attributable fraction of deaths, disability-adjusted life-years, years of life lost, and years lived with disability associated with CMM were estimated using the Global Burden of Disease Study 2019 by age, sex, year, location, and sociodemographic index at the global level. The slope index of inequality and concentration index were employed to measure socioeconomic-related health inequalities across countries. The number (million) of global deaths, disability-adjusted life-years, and years of life lost related to CMM were 2.9, 294.8, and 250.5 in 2019, showing decreases of 60.8, 57.4, and 60.7% since 1990. However, the number of years lived with CMM-related disability increased from 36.0 in 1990 to 44.3 in 2019. Additionally, the age-standardized rates of these 4 indicators showed varying degrees of decline. The global burden of CMM-related conditions differed with age and sex. The burden was the heaviest in western sub-Saharan Africa, especially in Chad. In terms of diseases, neonatal disorders represented the most significant burden attributed to CMM. Additionally, the CMM burden was more concentrated in regions with low sociodemographic indices, shown by the slope index of inequality and concentration index. The findings of this study highlight the ongoing global burden of CMM, particularly in terms of years lived with disability. Population-wide actions targeting the effective treatment and relief of CMM may reduce the CMM-related disease burden.
