Vertebral pathology and social status: A comparison between a post-medieval population from Arnhem and three contemporary populations from London

The goal of this thesis research is to test if the prevalence of vertebral pathological conditions reflect hard labour/tough life in the Arnhem Eusebiuskerk population and a lowstatus, middle-status and high-status population from London. The vertebral pathological conditions that have been compared are vertebral osteoarthritis, osteophytes, intervertebral disc disease, Schmorl’s nodes and fusion. First, the prevalence of the vertebral pathological conditions have been compared between the Arnhem population and the three London populations. After that, the prevalence has been compared between the males and females within each population followed by a comparison of the prevalence across the age categories. The latter has been done for each population as well. Lastly, the male and female sample of the populations have been compared separately between the Arnhem population and the three London populations. To summarise, there does seem to be a relationship between vertebral pathology...Show moreThe goal of this thesis research is to test if the prevalence of vertebral pathological conditions reflect hard labour/tough life in the Arnhem Eusebiuskerk population and a lowstatus, middle-status and high-status population from London. The vertebral pathological conditions that have been compared are vertebral osteoarthritis, osteophytes, intervertebral disc disease, Schmorl’s nodes and fusion. First, the prevalence of the vertebral pathological conditions have been compared between the Arnhem population and the three London populations. After that, the prevalence has been compared between the males and females within each population followed by a comparison of the prevalence across the age categories. The latter has been done for each population as well. Lastly, the male and female sample of the populations have been compared separately between the Arnhem population and the three London populations. To summarise, there does seem to be a relationship between vertebral pathology and social status in the Arnhem and London populations. Most vertebral pathological conditions are namely more prevalent in the low-status Arnhem population than in the higher status London populations. The prevalence of the vertebral pathological conditions in the lowstatus St. Arnhem population is similar to that of the low-status St. Bride’s Lower Churchyard population. Based on this, it can be inferred that the vertebral pathological conditions are more common in the lower status populations than in the higher status populations of this thesis. This could have been the result of the kind of labour these status groups were involved in. Furthermore, there does seem to be a difference in the prevalence of the vertebral pathological conditions between males and females; in three out of four populations (all except the St. Benet Sherehog population) males may have had harder working conditions than the females. When the prevalence in the male and female sample of the population were compared between Arnhem and the three London populations separately, a trend can be seen that may indicate that at least the males of the Arnhem population had harder working conditions than those in the other populations. The results have also shown that there are some biases. The first bias is that the statistically significant differences in the vertebral pathological conditions are more influenced by the male sample than by the female sample in all populations with Schmorl’s nodes likely being influenced by biological variation to some extent. Furthermore, the development of many of the vertebral pathological conditions are, at least to some extent, influenced by age in all populations.Show less
