Growth curves of immature bones from a Scottish island population of sixteenth to mid-nineteenth century: Shoulder girdle,ilium, pubis and ischium

Growth curves were prepared for length and various other dimensions, including some innovative ones, of the scapula, clavicle, first rib, ilium, pubis and ischium of ages up to 20 years including several immature and many full-term fetuses. Most curves showed, like the previously reported diaphyses of the limb bones, 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 growth spurt to be beyond doubt. The fetal dimensions were similar to those of Fazekas and Kósa and of other recent populations. For the post-natal stages of growth, no data are available for comparison but there was close correspondence with the growth curves of some ancient peoples, Amerindian, caucasoid and negroid, whose limb-bone growth rates had also been shown previously to be well below those of contemporary caucasoids. Thus it is argued that the shoulder-girdle and hip-bone data provided further evidence that this Scottish island 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 infantmortality rate, families were not large.
