Bone is a dynamic organ that continuously undergoes a process involving bone absorption and formation. Previous research has focused on average body mass estimations or pathological responses to body mass extremes. However, limited research has been done towards body mass estimation accuracy when body mass falls under an extreme. In the summer of 2011, the laboratory for human osteoarchaeology and the Dutch archaeological company Hollandia excavated a cemetery in Middenbeemster, The Netherlands. This skeletal population is unique since the cemetery could be linked to detailed historical information, including age, sex, and cause of death. The aim of this study was to study the prevalence of body mass extremes in the 19th century skeletal population. Furthermore, it has been studied whether the age related features experience influence from body mass and whether pathological lesions known to be associated with body mass have a correlation with body mass in the Middenbeemster skeletal population as well. Body mass estimations have been made with both the femoral head diameter and stature-bi-iliac breadth (STBIB). The age estimations, to assess the influence of body mass on age related features, have been made with both pubic symphyseal morphology and auricular surface morphology. The age estimations were compared to the true age at death, which were available from historical data. Special care has been taken in interpreting the results, because confounding factors may have caused bias. It appeared that the skeletal population of Middenbeemster was composed of primarily normal and overweight individuals, with a significant difference among males and females. Furthermore, there has not been a significant influence of body mass on age related features in this skeletal sample. The correlation of pathological lesions known to be associated with body mass was not significantly correlated with body mass in this skeletal sample. Together with other research, this study will be part of the enormously detailed historical framework of the population of 19th century Middenbeemster.Show less
