To evaluate global and regional trends in vitamin A deficiency and estimate its associated mortality burden among young children in 138 low-income and middle-income countries between 1991 and 2013.
Pooled analysis synthesizing population-based health survey data collected across 138 low-income and middle-income countries from 1991 through 2013.
Bayesian hierarchical modeling applied to estimate biochemical indicators of deficiency (serum retinol) and calculate attributable child mortality over time.
Demonstrated persistent regional disparities in the prevalence of childhood vitamin A deficiency across low- and middle-income regions over the 22-year period.
Identified significant ongoing burdens of preventable child deaths linked directly to vitamin A deficiency, primarily mediated through diarrhea and measles.
