Growth curves of immature bones from a Scottish island population of sixteenth to mid-nineteenth century: Limb-bone diaphyses and some bones of the hand and foot
Authors:A E W Miles  J S Bulman
Abstract:Growth curves were prepared for length of the diaphyses of the six major long bones of the limbs and for length of the calcaneus, talus, cuboid and the first metacarpals and metatarsals, of ages up to 20 years including several immature and many full-term fetuses. Most curves showed what appears to be a consistent adolescent growth spurt at about 17 years, but the number of specimens supporting these parts of the curves is too small for the validity of this spurt to be beyond doubt. The fetal diaphysis lengths were similar to those of Fazekas and Kósa and other recent populations but, compared with curves prepared from the Maresh radiographic data for recent caucasoids, the island diaphyseal growth rate, starting at about 4 months after birth, fell progressively behind so that, by 18 years for example, the femur was 90 mm shorter and the humerus 60 mm shorter than the Maresh equivalents. These findings accord with the short stature of the island adults (male mean 166.2 cm). The growth curves were closer to those of some ancient peoples, Amerindian, caucasoid and negroid, than to contemporary caucasoid. There is evidence of a secular change in growth in this island region because the calculated mean height at 18 years of this earlier island population is at the present time achieved by boys by about 14 years of age. Thus it is argued that the earlier population was affected by stunting factors. Although there is no skeletal evidence of malnutrition, there is plenty of evidence that the way of life was full of hardship in which the children shared. They took a full part in the arduous work involved in farming marginal-quality land; the houses were damp, cold, smoky and dark; they were overcrowded although, mainly because of the high infant-mortality rate, families were not large.
