Urbanization and respiratory stress in the Northern Low Countries: a comparative study of chronic maxillary sinusitis in two early modern sites from the Netherlands (AD 1626–1866)

The aim of this study was to investigate the relationship between urbanization and upper respiratory health in two early modern populations from the Netherlands. For this purpose, we analyzed the prevalence of chronic maxillary sinusitis in the adult urban population of Arnhem (n = 83) and in the rural village of Middenbeemster (n = 74). A slightly higher prevalence of chronic maxillary sinusitis was observed in the Arnhem sample (55.4%) compared with the Middenbeemster sample (51.3%), and these variations were not statistically significantly different. Although historical sources attest to the fact that life in the postmedieval settlements of Arnhem and Middenbeemster greatly differed, our results suggest that both environments exposed people to certain respiratory hazards. Furthermore, sinusitis prevalence was also investigated in correlation to sex, as urbanization in the Netherlands often involved women in factory work in direct contrast to the traditional domestic role they kept covering in rural environments. No significant differences were observed between males and females, both in an intersite (Arnhem males vs. Middenbeemster males; Arnhem females vs. Middenbeemster females) and in an intrasite (males vs. females at Arnhem; males vs. females at Middenbemster) comparison. As men and women in Arnhem worked on similar tasks, our results confirm that they were both exposed to similar risk factors. In Middenbeemster, where women mainly stayed inside taking care of the house while men worked the fields, the adverse weather conditions and continuous exposure to pollens and allergens may have enhanced men's chances of contracting chronic maxillary sinusitis. This study suggests that urbanization in the early modern Netherlands was in fact not inherently more detrimental than rural living. Future research incorporating a larger sample from other Dutch sites is being considered to better frame the complex etiology of sinusitis within the present understanding of historic regional variation in urbanization patterns.Bioarchaeolog
