Let them eat cake!: Correlating body mass to socioeconomic status in the post-medieval Netherlands by estimating body mass from femoral head breadth measurements

In the post-medieval Netherlands (c. 1650 to 1850 CE), large socioeconomic differences within urban centres existed, which appear to correlate with the diet each socioeconomic group had access to. 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.

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
