On the accuracy of estimating living stature from skeletal length in the grave and by linear regression

This study evaluates a method for obtaining stature estimates for populations represented by skeletal material, with individuals buried in a supine position. During the excavation of a Danish mediaeval cemetery, in situ skeletal length in the grave was measured from a point above the cranial point farthest from the body to the most distal point of the talus. The measurement was made with a folding rule placed on the sagittal midline of the skeleton, allowed to follow any curvature of the skeleton in situ. In the laboratory, stature was reconstructed anatomically, and this stature was regarded as an accurate estimate of living stature. Stature was also reconstructed from femur length by two linear regression procedures: 1) by sample and sex specific formulae, employing a leave‐one‐out approach, and 2) by sex wise formulae for Euro‐Americans from Trotter & Gleser (1952, American Journal of Physical Anthropology 10 : 463–514). Skeletal length in the grave and the two stature estimates based on linear regression were compared to anatomically reconstructed stature. Skeletal length in the grave estimated anatomically reconstructed stature with practically no bias (95% CI: −1.3–1.5 cm). Sample specific regression formulae estimated anatomically reconstructed stature also with no bias (95% CI: −1.2–1.1 cm). In contrast, statures calculated from Trotter & Gleser's regression formulae estimated anatomically reconstructed stature with a bias of about 4 cm (95% CI: 3.3–5.0 cm). Estimates of stature variance were biased for all three estimation procedures. However, for samples of adults, an adjusted variance estimate can be obtained by subtracting 8.7 cm² from the variance obtained from skeletal lengths in the grave. It is recommended to measure skeletal length in the grave whenever possible, and use this measurement for estimating statures for prehistoric and early historic populations.

Bioarchaeological Analysis of Iron Age Human Skeletons from Zambia

The Ingombe Ilede and Isamu Pati Iron Age sites in Zambia provide 47 human burials for analyses. Our new study provides demographic information (sex and age), evidence of trauma, infectious diseases as well as physiological and mechanical indicators of stress. We found a high mortality rate for infants and children. Most of the sample (65%) lacked indications of stress or infectious diseases, but a few had cribra orbitalia, osteoarthritis, osteophytosis and various dental pathologies. These conditions are known to be caused by diet, food processing, nutritional intake and cultural systems. In addition, there were low levels of degenerative joint disease and no evidence of trauma. The stature and body mass estimates show that these Iron Age people were similar in size and shape compared with contemporary South Africans. These data indicate a relatively healthy population with a well‐balanced diet and low afflictions of infectious and parasitic diseases. Copyright © 2012 John Wiley & Sons, Ltd.     

Two millennia of male stature development and population health and wealth in the Low Countries

This paper offers a review of shifts in average male stature and their relationship with health and wealth in the Low Countries from AD 50 to 1997. Twenty‐one population samples were studied to cover the full time span. To make data compatible, so‐called ‘virtual statures’ were used, i.e. the statures which adult males were supposed to have had at the end of their growth period, before they started shrinking by ageing. Original data were extracted from ‘in situ measured statures’, ‘calculated statures’ and ‘corrected cadaveric statures’. If possible, maximum femoral lengths were also collected from the same population samples to check whether trends in stature development were in agreement with raw skeletal data. A long phase of stature decrease from ca. 176 cm to 166 cm, a so‐called ‘negative secular trend’, was noticed from the Roman Period up to and including the first half of the 19th century. This was followed by a sharp and still ongoing increase in stature to 184 cm, a typical ‘positive secular trend’, from the second half of the 19th century to the present time. General shifts in stature and ‘outliers’ illustrative for the process are viewed in the context of socio‐economic, demographic, health and nutritional factors.

Stature estimation in a central Patagonian prehispanic population: development of new models considering specific body proportions

Stature estimation of individuals from extinct human populations is a classic topic in anthropology. The estimations, using regression formulae generated from different reference samples, display different results. This fact is related to inter‐populational differences in body proportions, which is a phenotypic trait mainly correlated with climatic parameters. The aim of this paper is to address the problem of stature estimation of an archaeological skeletal sample from Patagonia – a region for which there are no specific models available – using different methods and considering differences in body proportions between reference and target populations. The sample used in this analysis is composed of 35 Late Holocene adults of both sexes recovered in central Patagonia (Argentina). The stature of each individual was first reconstructed using the anatomical method [Fully G. 1956 . Une nouvelle me´thode de de´termination de la taille. Annales Medicine Legale 35 : 266–273], which has no assumptions on body proportions. The results were compared with estimations based on 32 different regression formulae [Trotter M, Gleser G. 1958. A re‐evaluation of estimation of stature based on measurements taken during life and the long bones after death. American Journal of Physical Anthropology 16 : 79–124. 10.1002/ajpa.1330160106] and three femur/stature ratios [Feldesman MR, Fountain RL. 1996. Race specificity and the femur/stature ratio. American Journal of Physical Anthropology 100 : 207–224. 10.1002/(SICI)1096‐8644(199606)]. The average reconstructed stature was 160.8 cm for females (95% confidence band = 155.6–166.2 cm), and 170.5 cm for males (95% confidence band = 168.8–172.2 cm). Most of the comparisons of the regression formulae and femur/stature ratios showed significant differences, which are explained by differences in body proportions between the Patagonian sample and the ones chosen as reference. Finally, a set of new equations was developed using simple regression techniques. It is suggested that whenever possible, population‐specific formulae should be used in archaeological studies. In any other situation, the choice of a reference population should be made by taking into account its geographic (latitudinal) provenance. Copyright © 2009 John Wiley & Sons, Ltd.     

New regression equations for stature estimation for medieval Scandinavians

Estimating stature from skeletal remains in an archaeological context requires appropriate methods that take into account possible temporal and spatial changes in body proportions. New regression equations—both least squares (LSQ) and reduced major axis (RMA) equations—were thus developed for estimating living stature from the long bone lengths of medieval inhabitants (N = 60) of Westerhus, Sweden. The living stature of these skeletal specimens was determined by using the anatomical method. Findings in this study reveal that LSQ regression equations systematically overestimate statures of short individuals and underestimate those of tall individuals, whereas the RMA equations—both combined sexes and sex‐specific equation—provide more accurate stature estimations for individuals of very different statures. The combined sexes RMA‐equations should be used for cases in which the sex is unknown because they provide more accurate stature estimations than sex‐specific equation with a wrong sex determination. These new equations are more appropriate than generally used regression equations for estimating statures of the medieval period Scandinavians. Copyright © 2009 John Wiley & Sons, Ltd.     

Non‐specific indicators of stress and their association with age at death in Medieval York: Using stature and vertebral neural canal size to examine the effects of stress occurring during different periods of development

Selective mortality can occur towards individuals who survive episodes of physiological stress, such as disease and malnutrition, during development. The skeletal elements affected depend on the timing of these stressful episodes. Studying multiple non‐specific indicators of stress can show which periods of development were affected and whether certain periods can be linked with selective mortality. To examine this method a preliminary study of 61 adult individuals from the Medieval population of Fishergate House, York was undertaken to examine small vertebral neural canal size and reduced adult stature. Previous studies have shown that selective mortality occurs towards individuals who display these non‐specific indicators of stress. Statistical analysis showed that small transverse neural canal diameter was significantly associated with early adult mortality for males and females and there was evidence of selective mortality towards females with reduced stature. This suggests that individuals who died in early adulthood experienced health insults during late childhood which stunted VNC growth but males in particular were not significantly affected by health insults after this age as they achieved a normal adult stature. Therefore it appears that health insults which occurred during late childhood had a greater influence on adult health in the Fishergate House population. This method could be expanded to provide more detailed information by using a greater variety of non‐specific indicators of stress which will allow more specific periods of development to be investigated.

Trends in adult stature of peoples who inhabited the modern Portuguese territory from the Mesolithic to the late 20th century

This study documents long‐term changes in stature from the Mesolithic to the late 20^th century in the territory of modern Portugal. Data utilised originated from published sources and from a sample of the Lisbon identified skeletal collection, where long bone lengths were collected. Mean long bone lengths were obtained from 20 population samples and compiled into nine periods. Pooled long bone lengths for each period were then converted to stature estimates. Results show three major trends: (1) a slow increase in stature from prehistory to the Middle Ages; (2) a negative trend from the Middle Ages to the late 19^th century; and (3) a very rapid increase in mean stature during the second half of the 20^th century. The political and territorial stability of the Kingdom of Portugal may have contributed to the greater heights of the medieval Portuguese, compared with the Roman and Modern periods. The negative secular trend was rooted in poor and unsanitary living conditions and the spread of infectious disease, brought about by increased population growth and urbanisation. Although the end of the Middle Ages coincided with the age of discoveries, the population may not have benefited from the overall prosperity of this period. The 20^th century witnessed minor and slow changes in the health status of the Portuguese, but it was not until major improvements in social and economic conditions that were initiated in the 1960s, and further progress in the 1970s, that the Portuguese grew taller than ever before. Since the Middle Ages other European countries have experienced similar oscillations, but showed an earlier recovery in stature after the industrial period.

The Value of Mid-Nineteenth Century Manufacturing Returns The Printed Census and the Manuscript Census Compilations Compared

The relationship between material inequality and health is the subject of considerable debate and may depend on how the relationship is defined. The author uses stature as a measure for cumulative health outcomes to illustrate that although there was an inverse relationship between inequality and health in the nineteenth century, greater average state wealth was associated with taller individual statures. He also poses and supports a biospatial relationship between the environment and stature. Greater direct sunlight (insolation) produces more vitamin D, which is related to adult terminal stature. Stature increased with population density and urbanization in states with lower population densities than the Midwest; however, stature decreased in states with population densities greater than those in the Midwest.     

Little waifs: estimating child body size from historic skeletal material

Child body weight formulae are developed from two radiographic studies that have measured the mid-diaphyses anteroposterior diameters of the humerus, femur and tibia. The results show that formulae that include a stature component are more reliable than those derived only from bone diameters and that formulae that use diameters of the femur or tibia to estimate body weight appear more to be reliable than those that use the diameter of the humerus. These formulae are applied to a historic nineteenth century child skeletal population excavated from a Sydney orphans cemetery. The results show that the orphans were shorter and lighter than comparable nineteenth century children. This difference is attributed to disrupted growth rates due to poor nutrition and health of children prior to their admission to the orphanage. © 1998 John Wiley & Sons, Ltd.
