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.
本研究的目的是调查来自族内通婚和族外通婚的同性儿童在身体尺寸上是否存在差异。横断面样本由285名6至10岁的儿童组成，其中136名男性和149名女性，他们就读于撒丁岛中东部城镇托尔托利的小学。每个性别的儿童分为两组：族内通婚组和族外通婚组，第一组包括父母出生在撒丁岛同一个村庄的儿童，第二组包括父母出生在两个不同地方的儿童。对于每个性别，以年龄为协变量的协方差分析显示，在考虑的35个人体测量变量上，两组儿童之间没有显著差异。此外，对于每个性别，在被视为营养状况指标的一些人体测量变量上，两组儿童之间也没有显著差异：皮褶厚度总和、腰臀比、体重指数、上臂总面积、上臂肌肉面积、上臂脂肪面积。我们得出结论，当族内通婚和族外通婚的撒丁岛儿童处于相似的营养状况时，他们的身体尺寸没有差异。
