Did Children in Medieval and Post‐medieval Poland Suffer from Scurvy? Examination of the Skeletal Evidence

Abstract

Late and post-medieval writings report that scurvy was a widespread condition in medieval and early historical Poland. Archaeological and historical data indicate that the diet of children was based on foods poor in vitamin C and contained small amounts of raw plant products. Also, historians emphasize that in medieval and post-medieval Poland there were seasonal fluctuations in food availability, frequently accompanied by poor harvests. Both resulted in long periods of poor nutrition, which affected children most severely. The aim of this study was to investigate skeletal manifestations of scurvy in subadult remains from medieval and post-medieval Poland. Following standards described by Ortner et al. (1999Ortner et al. ( , 2001 anatomical sites pathognomonic of scurvy in subadults (<17 years) were assessed for abnormal porosity and hypertrophic bone among skeletons excavated from three sites: Ostrów Lednicki (dated to the 11th-14th centuries AD), Cedynia (10th-14th centuries AD), and Słaboszewo (14th-17th centuries AD). In total 3.6% of all examined children were found to bear traces of vitamin C deficiency. The prevalence of scorbutic lesions was 4.5% for Cedynia, 2.6% for Ostrów Lednicki, and 3.6% for Słaboszewo. The majority of affected children were less than 7 years of age. Scurvy was likely more widespread in the living populations than it appears from the calculation of skeletal markers, because some individuals might have recovered or died before obvious traces became apparent. Also, in some children scurvy might not have reached an advanced stage, identifiable in the skeletal material. The prevalence of scurvy reflects not only dietary patterns but also food storage and preparation techniques adopted in the Polish territories during the Middle Ages, which contributed to low intakes of vitamin C.

“…It is possible that the non‐adults of Coronation Street suffered from acute afflictions, and simply did not survive long enough for skeletal responses to occur (DeWitte & Stojanowski, ; Vercellotti et al, ; Wood, Milner, Harpending, & Weiss, ). For example, in complete absence of vitamin C, an individual may die before skeletal indicators of scurvy can manifest, whether from the deficiency itself, or from increased susceptibility of the immune system to other infectious agents (Armelagos et al, ; Bourbou, ; Krenz‐Niedbała, ). Infectious disease was rife in urban environments of the 18th and 19th centuries, with measles, diphtheria, smallpox, whooping cough, and scarlet fever being common risks to the survival of the very young (Levene, ).…”

“…Although vascular holes in cortical bone are a normal anatomical feature, these are much fewer in number in a given area and more variable in size, frequently exceeding 1 mm in diameter (Ortner et al, 2001). Abnormal porosity of methaphyses was distinguished from porosity associated with normal remodelling on the basis of the size of the affected area, extending more than a centimeter from the end of the bone (Krenz-Niedbała, 2015). For all available anatomical sites, the lesions were recorded as absent, present, or non-observable.…”

“…With an economy emphasizing agriculture and herd management, meat and processed cereals were central to daily life in medieval and postmedieval Poland for both royals and commoners (Dembińska, ; Krenz‐Niedbała, ). Pork and beef were consumed regularly by the middle and upper classes, although pork is mentioned far more frequently in historic records, not because it was favored over beef but because of its greater availability for consumption due to pigs' ability to reproduce quickly and the ease at which they could be foddered using household food refuse (Dembińska, ).…”

“…Fish played an important role in medieval Polish diet as well, especially for those elites who could afford the expense of increasingly scarce species such as sturgeon (Dembińska, ; Krenz‐Niedbała, ; Singman, ). The Catholic Church of Poland imposed exacting regulations against the consumption of meat on days of fasting, which not only included Lent and other designated religious holidays but also each Wednesday and Friday during Ordinary Time within the church's liturgical year (Dembińska, ).…”
