Oral health and frailty in the medieval English cemetery of St Mary Graces

The analysis of oral pathologies is routinely a part of bioarcheological and paleopathological investigations. Oral health, while certainly interesting by itself, is also potentially informative about general or systemic health. Numerous studies within modern populations have shown associations between oral pathologies and other diseases, such as cardiovascular disease, certain types of cancer, and pulmonary infections. This article addresses the question of how oral health was associated with general health in past populations by examining the relationship between two oral pathologies (periodontal disease and dental caries) and the risk of mortality in a cemetery sample from medieval England. The effects of periodontitis and dental caries on risk of death were assessed using a sample of 190 individuals from the St Mary Graces cemetery, London, dating to ～AD 1350–1538. The results suggest that the oral pathologies are associated with elevated risks of mortality in the St Mary Graces cemetery such that individuals with periodontitis and dental caries were more likely to die than their peers without such pathologies. The results shown here suggest that these oral pathologies can be used as informative indicators of general health in past populations. Am J Phys Anthropol, 2010. © 2009 Wiley‐Liss, Inc.     

Survivorship and the second epidemiological transition in industrial-era London

Objectives

The second epidemiological transition describes a shift in predominant causes of death from infectious to degenerative (non-communicable) diseases associated with the demographic transition from high to low levels of mortality and fertility. In England, the epidemiological transition followed the Industrial Revolution, but there is little reliable historical data on cause of death beforehand. Because of the association between the demographic and epidemiological transitions, skeletal data can potentially be used to examine demographic trends as a proxy for the latter. This study uses skeletal data to examine differences in survivorship in London, England in the decades preceding and following initial industrialization and the second epidemiological transition.

Materials and Methods

We use data (from n = 924 adults) from London cemeteries (New Churchyard, New Bunhill Fields, St. Bride's Lower Churchyard, and St. Bride's Church Fleet Street) in use prior to and during industrialization (c. 1569–1853 CE). We assess associations between estimated adult age at death and time period (pre-industrial vs. industrial) using Kaplan–Meier survival analysis.

Results

We find evidence of significantly lower adult survivorship prior to industrialization (c. 1569–1669 and 1670–1739 CE) compared to the industrial period (c. 1740–1853 CE) (p < 0.001).

Discussion

Our results are consistent with historical evidence that, in London, survivorship was improving in the later 18th century, prior to the recognized beginning of the second epidemiological transition. These findings support the use of skeletal demographic data to examine the context of the second epidemiological transition in past populations.     

Reconstructing relationships among mortality, status, and gender at the Medieval Gilbertine Priory of St. Andrew, Fishergate, York

The varied relationships among status, gender, and mortality are complex, historically produced phenomena that shape people's lives and deaths in socially meaningful ways. Paleodemographic analysis coupled with acute sensitivity to site-specific context has the potential to move us toward a greater understanding of these experiences in the past. After considering the potential effects of migration and fertility on the age-at-death profiles of adult individuals interred at the Gilbertine Priory of St. Andrew, Fishergate, York (n = 200), it is asserted that these profiles primarily reveal expected and unexpected relationships among status, gender, and mortality in this Medieval context. Collectively, the long lives of religious-status males compared to other composite and gendered status groups suggest that they experienced a relatively comfortable existence despite periodic complaints of destitution. The postulated demographic advantage of high-status males did not materialize in the analysis, and a reevaluation of the skeletal evidence indicates that nearly 20% of these individuals died violently. Unexpectedly, moderate-status females shared a mortality profile similar to that of religious-status males and retained a demographic advantage over all other secular status groups. In contrast to the experiences of moderate-status females, low-status females had, on average, the shortest lives at St. Andrew's. This pattern is intimately linked to their restriction from crucial social and economic resources, and provides further evidence of their marginalization in York's wage-labor economy. Overall, these relationships suggest that traditional, highly stratified and gendered notions of Medieval status and mortality are not adequate for understanding the intricacies of everyday life and death at St. Andrew's.     

Epiphyseal union at the innominate and lower limb in a modern Portuguese skeletal sample, and age estimation in adolescent and young adult male and female skeletons

This study documents the timing of epiphyseal union at the innominate, femur, tibia, and fibula in a sample of modern Portuguese skeletons. The sample was taken from the Lisbon documented skeletal collection and it is comprised of 57 females and 49 males between the ages of 9 and 25. Individuals are mostly representative of the middle-to-low socioeconomic segment of the early 20th century Lisbon population. A total of 18 anatomical locations were examined for epiphyseal union using a three-stage scheme: 1) no union; 2) partial union; and 3) completed union, all traces of fusion having disappeared. Results show that females are ahead of males by 1-2 years and provide similar age ranges for the stages of union than previous studies. Some variations between studies can be explained by methodological differences between dry bone and radiographic observations. However, a review of the literature indicates that socioeconomic status of a given population seems to be of decisive importance to the rate of ossification and most of the differences in skeletal maturation across studies and populations can probably be ascribed to different levels of social and economic development of the societies in which the individuals lived. Although the effects of socioeconomic status in skeletal maturation are greater during childhood than in adolescence, as to make the timing of epiphyseal union a reliable estimate of age at death, they are not negligible and age estimates should take into account the likely socioeconomic status of the individual, whose remains are under examination.     

High childhood obesity in an Australian population

Objective: The objective was to determine the prevalences of overweight and obesity in regional Australian children and to examine the association between BMI and indicators of socioeconomic status (SES). Research Methods and Procedures: Regionally representative cross‐sectional survey of 2184 children, 4 to 12 years of age, was conducted, and the socio‐demographic characteristics of their parents from regional Victoria, Australia, 2003 to 2004, were obtained. Results: The prevalences of overweight and obesity were 19.3 ± 0.8% (proportion ± standard error) and 7.6 ± 0.6%, respectively, using international criteria, and the proportion of overweight/obese girls was significantly higher than that of boys (29.6 ± 1.4% vs. 23.9 ± 1.3%, χ² = 9.01, p = 0.003). Children from households of lower SES had higher odds of being overweight/obese; lower SES was defined by lower paternal education (adjusted odds ratio, 1.18; 95% confidence interval, 1.08 to 1.30) and lower area‐level SES (adjusted odds ratio, 1.13; 95% confidence interval, 1.02 to 1.25), adjusted for age, gender, height, and clustering by school. Discussion: The prevalences of overweight and obesity are increasing in Australian children by about one percentage point per year. This equates to ～40,000 more overweight children each year, placing Australian children among those at highest risk around the world. In addition, girls are more likely to be overweight, and there is a general trend for children of lower SES to be at even greater risk of overweight and obesity.     

The effect of sex on risk of mortality during the Black Death in London,A.D. 1349–1350

The Black Death of 1347–1351 was one of the most devastating epidemics in human history, and though it is frequently assumed that the epidemic killed indiscriminately, recent research suggests that the disease was selective, at least with respect to frailty. The purpose of this study is to determine whether the Black Death was similarly selective with respect to biological sex—that is, did either sex face an elevated risk during the epidemic or were men and women at equal risk of dying? A sample of 298 victims of the Black Death, from the East Smithfield cemetery in London, is compared to a pre‐Black Death normal mortality sample of 194 individuals from two Danish urban cemeteries, St Mikkel Church (Viborg) and St Albani Church (Odense). To assess the effect of sex on risk of death, sex is modeled as a covariate affecting the Gompertz–Makeham model of adult mortality. The results suggest that sex did not strongly affect risk of death in either the normal mortality or Black Death samples. These results are important for improving our understanding of Black Death mortality patterns. This is essential for understanding the effects the Black Death had on European populations, and the methods used here can potentially be informatively applied to investigations of other episodes of epidemic diseases in past populations.

Estimating the age structure of a buried adult population: A new statistical approach applied to archaeological digs in France

Paleodemographers have developed several methods for estimating the age structure of historical populations in absence of civil registration data. Starting from biological indicators alone, they use a reference population of known sex and age to assess the conditional distribution of the biological indicator given age. However, the small amount of data available and the unstable nature of the related statistical problem mean that most methods are disappointing. Using the most reliable reference data possible, we propose a simple statistical method, integrating the maximum amount of information included in the actual data, which quite significantly improves age estimates for a buried population. Here the method is applied to a French cemetery used from Late Antiquity to the end of the Early Middle Ages. Am J Phys Anthropol, 2013. © 2012 Wiley Periodicals, Inc.     

Determination of adult stature from metatarsal length

The results of a study to determine the value of foot bones in reconstructing stature are presented. The data consist of length measurements taken on all ten metatarsals as well as on cadaver length from a sample of 130 adults of documented race, sex, stature, and, in most cases, age. Significant correlation coefficients (.58-.89) are shown between known stature and foot bone lengths. Simple and multiple regression equations computed from the length of each of these bones result in standard errors of estimated stature ranging from 40-76 mm. These errors are larger than those for stature calculated from complete long bones, but are approximately the same magnitude for stature calculated from metacarpals and fragmentary long bones. Given that metatarsals are more likely to be preserved unbroken than are long bones and given the ease with which they are accurately measured, the formulae presented here should prove useful in the study of historic and even prehistoric populations.     

Physical stature of adult Tsimane’ Amerindians, Bolivian Amazon in the 20th century

We examine the association between exposure to the market and Western society on the height of adult Tsimane', a foraging-farming society in the Bolivian Amazon. As with other contemporary native peoples, we find little evidence of a significant secular change in height during 1920-1980. Female height bore a positive association with own schooling and fluency in spoken Spanish and with maternal modern human capital (schooling, writing ability, and fluency in spoken Spanish), but male heights bore no association with parental height or with modern human capital. The absence of a secular change likely reflects the persistence of traditional forms of social organization and production that protect health.     

Estimation of adult skeletal age‐at‐death using the Sugeno fuzzy integral

Age‐at‐death estimation of an individual skeleton is important to forensic and biological anthropologists for identification and demographic analysis, but it has been shown that the current aging methods are often unreliable because of skeletal variation and taphonomic factors. Multifactorial methods have been shown to produce better results when determining age‐at‐death than single indicator methods. However, multifactorial methods are difficult to apply to single or poorly preserved skeletons, and they rarely provide the investigator with information about the reliability of the estimate. The goal of this research is to examine the validity of the Sugeno fuzzy integral as a multifactorial method for modeling age‐at‐death of an individual skeleton. This approach is novel because it produces an informed decision of age‐at‐death utilizing multiple age indicators while also taking into consideration the accuracies of the methods and the condition of the bone being examined. Additionally, the Sugeno fuzzy integral does not require the use of a population and it qualitatively produces easily interpreted graphical results. Examples are presented applying three commonly used aging methods on a known‐age skeletal sample from the Terry Anatomical Collection. This method produces results that are more accurate and with smaller intervals than single indicator methods. Am J Phys Anthropol 2010. © 2009 Wiley‐Liss, Inc.     

A socioeconomic analysis of secular trends in isonymy in the Jewish community of Gibraltar: 1820 to 1939

This study examines secular trends in the magnitude of inbreeding in the Jewish community of Gibraltar over a 120 year period. Analysis of isonymous unions by socioeconomic status revealed distinctive differences between high versus mid/low status unions. Factors responsible for the elevated rate of inbreeding among the professional/mercantile class and its secular trend are discussed.     

Aging and secular change in adult stature in rural Colombia

Age-associated changes in adult stature of a cross-sectional sample of 634 adults from rural Colombia were estimated by multiple regression of stature and age controlling for subischial length, and from equations predicting maximum attained stature from subischial length. From these analyses the estimated rate of loss in stature due to aging per se for men was 0.12 cm/yr, while for women it was 0.03 cm/yr. When corrected for aging, several secular trends in adult stature were evident, although none were statistically significant.     

Income-related inequalities in denture-wearing by Europeans aged 50 and above

doi: 10.1111/j.1741‐2358.2011.00590.x
Income‐related inequalities in denture‐wearing by Europeans aged 50 and above Background: Despite its importance for the planning of future treatment needs and an optimised allocation of health care resources, only little is known about socio‐economic inequalities in denture‐wearing by late middle‐aged and elderly generations. Objectives: To describe income‐related inequalities in denture‐wearing by elderly populations residing in different European countries. Material and methods: Data from the Survey of Health, Ageing and Retirement in Europe (SHARE Wave 2) were used to assess income‐related inequalities in denture‐wearing by means of Concentration Indices (CI) for populations aged 50+ from 14 different European countries. Results: We could identify a significant disproportionate concentration of denture‐wearing amongst the poor elderly populations in Denmark (CI = ?0.3534, corresponding to the highest level of inequality), Sweden (CI = ?0.3479), Switzerland (CI = ?0.2013), Greece (CI = ?0.1953), the Netherlands (CI = ?0.1413), France (CI = ?0.1339), Austria (CI = ?0.0974), Czech Republic (CI = ?0.0959), Belgium (CI = ?0.0947), Germany (CI = ?0.0762), Ireland (CI = ?0.0575) and Spain (CI = ?0.0482, corresponding to the lowest level of pro‐poor inequality). Poland became evident as the only country in which individuals from the upper end of the income scale wear more dentures than their peers from the lower end of the income scale (CI = 0.0379). No significant income‐related inequalities were observable in Italy. Conclusions: There is considerable income‐related inequality in denture‐wearing by several elderly populations in Europe. Future resource planning for prosthetic care should, thus, specifically distinguish between the treatment needs of different socio‐economic groups within elderly populations.     

Estimation of adult stature from the calcaneus and talus

Calcanei and tali of 100 skeletons in the Hamann–Todd Collection at the Cleveland Museum of Natural History were measured. The skeletons represented 50 males and 50 females distributed equally by race, i.e., whites and blacks. Linear-regression equations, with standard errors ranging from 4.09 to 6.11 cm, were derived from these measurements for the purpose of estimating stature. Two independent control samples, including one comprised of remains of American servicemen lost in World War II and the Korea and Vietnam wars, were tested with relatively accurate results. © 1995 Wiley-Liss, Inc.     

The estimation of adult stature from metacarpal bone length

Stature was measured (in cm) in 166 (120 male; 46 female) predominantly white adults (age range: 17–87 years). A radiograph of one hand of each subject was taken (for routine diagnostic purposes) and the inter-articular length of all five metacarpal bones was measured with a sliding caliper. These metacarpal lengths were then adjusted to compensate for enlargement during radiography. A significant correlation coefficient between stature and metacarpal length was observed in both sexes. Regression equations were computed from the length of each metacarpal, by which living stature may be fairly accurately estimated in the absence of any complete limb bones. The difference between our estimates and those obtained by more orthodox methods is usually less than 3%.
