Vitamin D deficiency at Middenbeemster and Hattem is the result of cultural variables that limit an individual’s exposure to sunlight. During growth spurts, such as the pubertal growth spurt, high demand for vitamin D puts individuals at an increased risk for developing conditions such as rickets. This thesis aims to determine whether adolescent rickets can be identified in archaeological skeletal remains, and how to quantify the observed changes. The current work also aims to use the prevalence of adolescent rickets to understand the underlying social changes affecting individuals in the Netherlands in the 17th to 19th centuries. Two collections of archaeological human remains from the 17th to 19th century Dutch sites of Middenbeemster (n=246) and Hattem (n=117) were evaluated using macroscopic, metric, radiographic, and micro-CT analysis of skeletal remains. Adolescent individuals were evaluated for signs of active adolescent rickets, and adults were evaluated for signs of residual adolescent rickets. Statistical analysis found that measurements quantifying shape changes at the distal ulna, medial clavicle, and sacral angle can be used to identify adolescent rickets in a skeletal sample.
Adolescent rickets at Middenbeemster and Hattem was found to be distributed equally amongst males and females and was found to occur less frequently than rickets in infants and children from the same population. Rickets in adolescents was most likely caused by the onset of new jobs or roles resulting in individuals remaining indoors for long periods of time. Rickets may have also been caused by illness. By identifying rickets in adolescents, this thesis provides a window to view the changing roles of individuals as they begin to occupy new spaces in their transition from children into adults, thus providing a novel way to investigate the lives of adolescents. / Thesis / Master of Arts (MA)
