While low socioeconomic status (SES) often evokes the association of low body mass as a result of having little access to food, modern-day studies show that people living in poverty actually have a higher body mass than contemporaries of higher socioeconomic status. This thesis aims to study to what extend the relationship between body mass and socioeconomic status existed in the post-medieval Netherlands, with a focus on the role of diet and lifestyle. This was done by studying two post-medieval urban populations: one with a low SES from the Eusebiuskerk in Arnhem and one with a high SES from the Broerenkerk in Zwolle. Body mass was estimated by applying body mass estimation equations developed by Ruff et al. (2012) to measurements of the femoral head breadth. Statistical analyses were applied to compare the mean body mass between the high- and low SES samples. The males and females were compared separately. The results showed a positive relation between body mass and low SES. However, this relation was only statistically significant between the male samples. As males had more access to food because of their role in the household, the calorie-dense diet of low SES males could have allowed them to consume more calories than their high SES male counterparts who had access to a more varied diet with overall less calories. Low SES males furthermore performed more physically intense labour than the high SES males, increasing their muscle mass. Both female groups likely had less access to food in general, thus it is plausible that bottom line they consumed similar amount of calories. Also, both female groups would have mostly performed similar household tasks leading to no difference in muscle mass. Lastly, the femoral head is less responsive to changes in body mass in females which could attribute to these results. It can thus be concluded that that body mass can change as a result of status-differences in diet and labour. Based on the sites of Zwolle and Arnhem there seems to be a positive relation between low socioeconomic status and body mass in the post-medieval Netherlands.Show less

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
