Abstract
The association of stature and age with measures of 2nd metacarpal cortical bone growth is investigated in a sample of 1586 radiographs taken from Guatemalan Ladino children aged 1-7 yr in a setting of endemic mild-to-moderate malnutrition. For given stature, chronological age is positively associated with cortical thickness and cortical area and negatively associated with periosteal and medullary diameter. These different partial correlations are seen as evidence of different kinds of growth. Correlations of cortical bone variables with body size within a chronological age are shown to derive from the overall relationship between age, stature and measures of cortical bone.
