Anthropometric variation between migrants and non-migrants: Orkney Islands, Scotland

Anthropometric measurements on a non-migrant sample consisting of 174 males and 148 females aged 21 to 75 resident in the Orkney Islands are compared with measurements on 91 males and 96 females who migrated as adults to the Aberdeen area of Scotland. Covariance analysis, adjusting for age effects, reveals differences in a number of anthropometric variables, with migrants showing smaller dimensions in several cases. For most variables the differences are more marked in females. Significantly smaller values are found in upper arm circumference, bicondylar humerus and head breadth in female migrants, and in bicondylar humerus in male migrants. Biacromial and head length dimensions are significantly greater in female migrants. There is no significant effect of duration of residence in the new environment on the anthropometric values of migrants.
