title: The question of differences in body dimensions between children from endogamic and exogamic matings: a study in Sardinia.
abstract: The aim of this study is to investigate whether there are differences in body dimensions between children of the same sex from endogamic and exogamic matings. The cross-sectional sample consisted of 285 children, 136 males and 149 females, 6 to 10 years old, attending elementary schools in Tortolí, a town in east-central Sardinia. The children of each sex were divided into two groups: endogamic and exogamic, the first including children from parents born in the same Sardinian village, the latter children from parents born in two different places. For each sex, ANCOVA with age as covariate revealed no significant differences between the two groups of children for the 35 anthropometric variables considered. Moreover, for each sex, there were no significant differences between the two groups of children for some anthropometric variables considered to be indicators of nutritional status: sums of skinfold thicknesses, waist/hip ratio, body mass index, total upper arm area, upper muscle arm area, upper arm fat area. We conclude that when Sardinian children of endogamous and exogamous unions are in similar nutritional conditions, they do not differ in body dimensions.
