Associations between arterial oxygen saturation, body size and limb measurements among high-altitude andean children

Abstract

The relative influences of hypoxia and other environmental stressors on growth at alti-tude remain unclear. Previous work demonstrated an association between peripheral arterial oxygen saturation (SPO2)and anthropometry (especially tibia length) among Tibetan and Han children at altitude. We investigated whethersimilar associations exist among Andeans, and the patterning of associations between SPO2and anthropometry
