Hemoglobin increases with elevation as an adaptive response to lower blood oxygen saturation. This secondary data analysis examines the cross-sectional association between hemoglobin and elevation among school-aged children with data from nine population-based surveys. The paper calculates the hemoglobin adjustments required for each 500 meter increase in elevation and evaluates the impact of these adjustments on anemia prevalence.
