title: The relation of adiposity and body size to chronological age in olive baboons.
abstract: Mixed-longitudinal data on adiposity and body size were taken on 250 male and 452 female olive baboons aged between birth and 8 years. Adiposity was measured as skinfold thickness at the neck, subscapular, suprailiac, and triceps sites; body size measures included weight, crown-rump length, and triceps circumference. Males and females were treated independently and compared for gender differences. Data were tabulated to examine the relation of the somatometric variables to age and the patterns of association among the variables. Females averaged larger skinfold values at all sites for most ages. Males were significantly heavier, longer, and exhibited greater triceps girth at all ages except birth and 1 year where no significant gender difference was found for crown-rump length. In general the three measures of body size were significantly correlated at all ages as were the four measures of adiposity. Significant associations between adiposity and body size measures were not consistent among various ages.
