To understand this, three methods were used: linear enamel hypoplasia, cribra orbitalia, and porotic hyperostosis. In total, 84 skeletons were analysed. The populations have been analysed with each other as well as on their own. The methods have been compared to each other to understand whether they might relate to each other and whether it was likely that they occurred within a skeleton simultaneously. Results showed that there was no statistical significance within or between the sex and age-at-death categories within and between the populations, except for the cribra orbitalia results between the population of the Eusebiuskerk and the Broerenkerk. This has been linked to status: the population buried in the Broerenkerk was of a higher status than the population of the Eusebiuskerk. Although they were likely not extremely rich, as illustrated by the job names presented on the covering slabs, they likely had better access to food. The population of the Eusebiuskerk was likely to be of a very poor status due to trade tokens found with the individuals and because they were buried in the northern church grounds. The fact that the individuals from Zwolle showed less linear enamel hypoplasia might be the result of them experiencing less long term stress. Poor individuals lived close together in guesthouses, which means that illnesses could spread faster. So, it is clear that stress affected statuses differently, and that individuals from Arnhem were more fragile as a result. Yet, care must be taken as limitations are present.Show less

This thesis testedseven already existing (sets of) formulae using dental root translucency as a parameter, that weredeveloped on samples from various geographical regions, on the known sex and age-at-death sample from the Middenbeemster Collection housed at the Laboratory of Human Osteoarchaeology at the Faculty of Archaeology in Leiden University, The Netherlands. A total of 77 individuals werestudied, resulting in age-at-death estimations for 67 of theseindividuals. To test if a more accurate formula could be developed for the Middenbeemster Collection, and even Dutch osteoarchaeological human remains, several new formulaewere trailedresulting in the following formula (T = translucency in mm):Age =19.832+7.667*T +-0.299*T2.With this formula, no statistical difference was found between males and females and seemed not to be affected by dental disease.The new formula was tested on twenty-onenew individuals from the Middenbeemster Collection and twenty individuals from Arnhem, Eusebiuskerk, allonly having an estimated osteological age category. The newly derived formula performed well in the forty-one newly studied individuals, bringing the total number of studied individuals with an age-at-death estimation to 108 individuals. The small sample size and slight underrepresentation should be addressed in future research that either has to enlarge the known age-at-death sampleand/or enlarge the estimated age-at-death sampleto test the presented formula of this thesis.Show less

Nonetheless, palaeopathologists and bioarchaeologists in general seem to not have developed any interest in the topic, which at present remains unrepresented in the bioarchaeological literature. Clinical research on respiratory diseases has highlighted a link between poor air quality and the prevalence of chronic maxillary sinusitis, especially in developing countries where biomass fuels are employed in daily activities such as cooking and heating without a proper ventilation. Since historical sources suggest that respiratory diseases were equally affecting people in the past as they are in the present, if air quality is to be considered a significant triggering agent, it makes sense to expect the highest rates of chronic maxillary sinusitis in populations exposed to consistent concentrations of air pollutants, rather than on populations living in open spaces such as the countryside. This study considers two populations from Post-Medieval the Netherlands, each one representative of a low-class rural and urban environments respectively. A total of 105 individuals were examined in this study. 50 (47.6%) of the examined individuals showed signs of sinusitis in one or both maxillary sinuses. Even if a significant prevalence was found in the urban context (56.9% versus the 38.9% recorded in the rural population), the initial hypothesis was nevertheless questioned by the consideration of several factors which may have increased the chances of developing sinusitis in the past but that are no longer observable on the skeleton. Some of those are allergic reactions and localised inflammations of the respiratory tract. As these are no longer observable on skeletal remains and therefore are barely mentioned in bioarchaeological literature, the conclusions of this thesis encouraged future research to focus on respiratory diseases as their aetiologies are more complex than it was assumed in previous studies.Show less

Few extant methods have been able to match the accuracy rates of methods designed for adult remains and those that have failed to achieve similarly acceptable rates when tested on a population other than the one on which the method was originally developed. Due to this, children are habitually excluded from archaeological investigations since a major component of their biological profiles is considered inaccessible. A definitive and reliable technique to estimate sex in non-adult osteological remains would contribute greatly to the field of osteoarchaeology, allowing for the refinement of osteological age estimation and growth studies as well as more perceptive interpretations of the social, economic, or environmental implications of osteological evidence. In this thesis, a population-specific statistical approach to non-adult sex estimation based on the crown and cervical dimensions of the permanent canines and maxillary first molars was tested on the documented post-medieval skeletal collection of Middenbeemster, the Netherlands. The odontometrics of the adult component of the population (n = 76) were used to develop 14 binomial logistic regression formulae, which were subsequently applied to the non-adult individuals of the same population (n = 15). Though the two formulae based on the maxillary first molar odontometrics performed little better than chance, all 12 of the formulae based on the permanent canines achieved accuracy rates above 75%, with eight surpassing 85% and five achieving 100% accuracy. It was demonstrated that as little as one dimension of the permanent maxillary or mandibular canine can be used to estimate sex with an acceptable level of confidence. Due to the necessity of a permanent canine, this method is only applicable to individuals aged five years and above at the time of death, including adult individuals whose state of preservation does not allow for morphometric sex estimation or whose morphological sex estimate was indeterminate. By allowing reliable sex estimation in non-adult skeletal remains, this method makes it possible to gain insights into the past lives of non-adult individuals, who all too often seem invisible in archaeological and historical narratives.Show less
