This study evaluates possible differences in body dimensions among children from matings of different exogamy levels. The cross-sectional sample consisted of 867 children, 435 males, and 432 females, 6-10 years old, attending elementary schools in the metropolitan area of Cagliari, the capital of Sardinia (Italy). The children were divided into two groups according to the level of exogamy. The first group consisted of children of parents born in the same Sardinian municipality and was considered endogamous sensu stricto. The second group included children of parents born in municipalities from different Sardinian linguistic domains and was considered exogamous. The Mann-Whitney test did not reveal significant differences between the two groups of children in the mean rank values of the 36 anthropometric variables considered, with the exception of cephalic circumference in males and chest depth in females. In particular, there were no significant differences for anthropometric variables considered to be indirect indicators of nutritional status: sum of skinfolds, waist/hip ratio, body mass index, total upper arm area, upper arm muscle area, and upper arm fat area. The results indicate that Sardinian children from marriages of different exogamy levels do not differ in body dimensions if they grow up with similar nutritional and socioeconomic conditions.
本研究评估了不同异族通婚水平的交配所生育的儿童在身体尺寸方面可能存在的差异。该横断面样本包括 867 名儿童，其中男 435 名，女 432 名，年龄在 6-10 岁之间，来自意大利撒丁岛首府卡利亚里大都市区的小学。这些儿童根据异族通婚水平分为两组。第一组由出生在同一撒丁岛市的父母所生的儿童组成，被认为是严格意义上的同宗婚姻。第二组包括出生在来自不同撒丁岛语言区的父母的儿童，被认为是异族通婚。曼-惠特尼检验未发现两组儿童在 36 项人体测量变量的平均秩值上存在显著差异，除了男性的头围和女性的胸围。特别是，对于被认为是营养状况间接指标的人体测量变量，没有差异：皮褶总和、腰臀比、体重指数、总上臂面积、上臂肌肉面积和上臂脂肪面积。研究结果表明，如果撒丁岛儿童在相似的营养和社会经济条件下成长，那么他们的身体尺寸在异族通婚水平不同的婚姻中没有差异。
