Abstract: Dental data can reveal evidence for a past population's oral health, nutrition, and certain cultural activities. This study aims to explore oral health and dental attrition during the late Bronze Age in order to explore health outcomes in different subgroups as well as aspects of foodways and changes in subsistence strategies during the second millennium BCE in northwest China. To do this, the skeletal remains of adult individuals associated with the Siwa material culture (1400–1100 BC) from the Mogou site (n = 28) were macroscopically assessed and compared with previously published data derived from a subsample of individuals associated with Qijia period material culture complex (1750–1400 BC) from the same site. The results show that the Siwa‐period population experienced a high frequency of carious lesions and antemortem tooth loss associated with advanced attrition (of both molars and nonmolar teeth), which did not vary significantly by sex. Females had a higher prevalence of carious lesions and antemortem tooth loss than did males, while males had a higher prevalence of dental calculus. These male/female health outcomes are also attested during the earlier Qijia period at the Mogou site. The Siwa period differs from the Qijia in that females experienced slightly worse attrition than their predecessors. Overall, oral health does not diverge significantly between the Qijia and Siwa periods, suggesting that the factors that contributed to oral health including dietary practices may have persisted diachronically for individuals buried at this site.

The natural environment of the Gansu-Qinghai region in northwest China exhibits spatial variation, resulting in distinct adaptive strategies among populations in different geographical areas. In this study, we analyzed the diachronic trend and regional variations in caries prevalence among 10 different middle and late-Holocene groups by examining dental caries data to explore the correlation between different adaptation strategies and caries frequency. Frequency data was used to compare dental caries between populations, and the Chi-square test was employed to detect statistical differences. A multidisciplinary approach was employed to investigate the relationship between these changes and the adaptive strategies adopted by the populations in this region. The result shows that there was a gradual increase in caries prevalence over time in eastern Gansu, which corresponded with development of millet farming and social hierarchy. In the Hexi Corridor, caries prevalence exhibited fluctuations attributable to climate variability, human migration, and regime change. The research proposes that changes in adaptive strategies due to various social and environmental factors are reflected in human teeth, while also presenting a novel endeavor of aggregating a large, multisite bioarchaeological dataset in order to investigate the interactions between Holocene populations and palaeoenvironments in northwest China.

Abstract: Skeletal fluorosis is a systemic chronic disease caused by long‐term intake of excessive fluoride, which accumulates in bone tissue and causes changes to the bone and periosteal tissue. Skeletal fluorosis is rarely considered in paleopathological analyses, but in areas with relatively high fluoride in the environment, it may be an important cause of bone hyperplasia. In this study, we observed pathological lesions consistent with fluorosis on two human skeletons from the Ming Dynasty (1368–1644 CE) excavated from a cemetery in western Henan Province. By using an electron microprobe to measure the fluoride content in the teeth, and by considering the living conditions in the area during the Ming Dynasty, we conclude that the remains show evidence of skeletal fluorosis. We also consider the content of fluoride in the local groundwater, the local way of life, and other factors, to identify potential causes of skeletal fluorosis in this population and demonstrate that environmental factors were the main cause. This offers insight into the relationship between humans and their environments in China, especially western Henan Province, in the historical past. It also demonstrates the unique contributions bioarchaeology can make to environmental health studies and studies of the history of health.

Climate change is an indisputable threat to human health, especially for societies already confronted with rising social inequality, political and economic uncertainty, and a cascade of concurrent environmental challenges. Archaeological data about past climate and environment provide an important source of evidence about the potential challenges humans face and the long-term outcomes of alternative short-term adaptive strategies. Evidence from well-dated archaeological human skeletons and mummified remains speaks directly to patterns of human health over time through changing circumstances. Here, we describe variation in human epidemiological patterns in the context of past rapid climate change (RCC) events and other periods of past environmental change. Case studies confirm that human communities responded to environmental changes in diverse ways depending on historical, sociocultural, and biological contingencies. Certain factors, such as social inequality and disproportionate access to resources in large, complex societies may influence the probability of major sociopolitical disruptions and reorganizations-commonly known as "collapse." This survey of Holocene human-environmental relations demonstrates how flexibility, variation, and maintenance of Indigenous knowledge can be mitigating factors in the face of environmental challenges. Although contemporary climate change is more rapid and of greater magnitude than the RCC events and other environmental changes we discuss here, these lessons from the past provide clarity about potential priorities for equitable, sustainable development and the constraints of modernity we must address.

This article presents outcomes from a Workshop entitled "Bioarchaeology: Taking Stock and Moving Forward," which was held at Arizona State University (ASU) on March 6-8, 2020. Funded by the National Science Foundation (NSF), the School of Human Evolution and Social Change (ASU), and the Center for Bioarchaeological Research (CBR, ASU), the Workshop's overall goal was to explore reasons why research proposals submitted by bioarchaeologists, both graduate students and established scholars, fared disproportionately poorly within recent NSF Anthropology Program competitions and to offer advice for increasing success. Therefore, this Workshop comprised 43 international scholars and four advanced graduate students with a history of successful grant acquisition, primarily from the United States. Ultimately, we focused on two related aims: (1) best practices for improving research designs and training and (2) evaluating topics of contemporary significance that reverberate through history and beyond as promising trajectories for bioarchaeological research. Among the former were contextual grounding, research question/hypothesis generation, statistical procedures appropriate for small samples and mixed qualitative/quantitative data, the salience of Bayesian methods, and training program content. Topical foci included ethics, social inequality, identity (including intersectionality), climate change, migration, violence, epidemic disease, adaptability/plasticity, the osteological paradox, and the developmental origins of health and disease. Given the profound changes required globally to address decolonization in the 21st century, this concern also entered many formal and informal discussions.

Abstract: Bioarchaeological research provides unique insights on human adaptation, diet, lifestyle and epidemiology. The Mogou Bioarchaeology Project explores how health was affected by the Bronze Age transition in north-west China. Preliminary results reveal that the inhabitants experienced substantial physiological stress, infectious disease and lethal trauma.

ObjectivePaleopathological evidence of cancer from past populations is rare, especially outside of Europe and North Africa. This study expands upon the current temporal and spatial distribution of cancer by presenting a probable case of multiple myeloma from Bronze Age China.MaterialThe human skeletal remains of an adult male from the Qijia culture horizon (1750-1400 BCE) of the Bronze Age cemetery of Mogou (), located in Gansu Province, Northwest China.MethodsThe human skeletal remains were assessed macroscopically and radiographically using plain x-rays.ResultsMultiple ovoid-shaped osteolytic lesions with sharply demarcated margins were observed. The axial skeletal had the greatest involvement, specifically the vertebrae, ribs, and sternum. Radiographic imaging revealed more extensive destruction of cancellous than cortical bone, indicating that the marrow was the focal point of the disease.ConclusionBased on the nature, distribution, and radiographic appearance of the lesions, the most likely diagnosis is multiple myeloma.SignificanceThis is one of the only cases of cancer identified in archaeological human skeletal remains from East Asia and is the first published case of a hematopoietic malignancy from mainland China. The analysis and publication of examples of neoplasia from areas that expand upon the current known temporal and spatial distribution is necessary in order to better reconstruct the history and evolution of cancer.LimitationsPoor skeletal preservation prevented the full extent of osteolytic lesions to be observed.Suggestions for future researchBy placing case studies such as this into a temporal and spatial framework, it is possible for future research to begin to interrogate possible underlying causes of cancer in ancient populations within the context of changing environmental conditions and subsistence strategies.

We set out to assemble this Special Issue of IJPP with three goals in mind: (1) to familiarize Anglophone readers with research on paleopathology conducted by Chinese scholars; (2) to enhance interest in paleopathological research among Chinese scholars, and to foster the use of differential diagnosis as the key mode of paleopathological analysis; and (3) to initiate integration of pathological analysis of human skeletal collections with historical records documenting early medical practices, epidemics, development and age-related diseases, and demographic records. The collection of papers that follows presents new data, from a range of time periods and geographic and social contexts, that we feel reflect the diversity, dynamism, and enormous scope of archaeology in China today. Themes such as infectious disease history, interpersonal violence, and comorbidity as a methodological issue are addressed by multiple papers. However, as the special issue developed, we also came to a slow appreciation of structural constraints that made our original goals difficult to attain within the current state of our discipline, of which the language barrier represents only a minor issue. This introductory paper is intended to contextualize the Special Issue, and help readers understand the intrinsic and extrinsic factors that influence paleopathological research in China and its interactions with similar research in other parts of the world. :IJPP，:(1);(2)，;(3)、、。、，、。、。，，，，。，，.

This research explores how social and environmental factors may have contributed to conflict during the early Bronze Age in Northwest China by analyzing violent trauma on human skeletal remains from a cemetery of the Qijia culture (2300-1500 BCE). The Qijia culture existed during a period of dramatic social, technological, and environmental change, though minimal research has been conducted on how these factors may have contributed to violence within the area of the Qijia and other contemporaneous material cultures. An osteological assessment was conducted on 361 individuals (n = 241 adults, n = 120 non-adults) that were excavated from the Mogou site, Lintan County, Gansu, China. Injuries indicative of violence, including sharp- and blunt-force trauma that was sustained ante- or peri-mortem, were identified, and the patterns of trauma were analysed. Violent injuries were found on 8.58% (n = 31/361) of individuals, primarily adult males. No evidence of trauma was found on infants or children. Cranial trauma was found on 11.8% (n = 23/195) of the adult individuals examined. Of these, 43.5% (n = 10/23) presented with severe peri-mortem craniofacial trauma. The high rate of perimortem injuries and their locations indicate lethal intent. This lethality, in addition to the fact that individuals with trauma were predominantly male, suggest intergroup violence such as raiding, warfare, or feuding. Both social and environmental factors may have contributed to this conflict in the TaoRiver Valley, though future systematic archaeological and paleoenvironmental data will be needed to disentangle the many potential causal factors.

This paper describes the morphology of the feet of a population of elite women from the Ming dynasty (1368-1644 CE) in Shaanxi province. This is a social stratum, time, and place in which foot binding was practiced. Among a group of 31 skeletons exhumed from the cemetery, eight were women with well-preserved foot bones. Macroscopic examination revealed that half these women (4/8) had clearly altered foot bones: the metatarsal bones, and the few observable phalanges, were gracile and small, while the tarsal bones exhibited a slight reduction in size but no dramatic change in morphology. The other half of the women (4/8) had apparently unmodified metatarsal bones. T-tests comparing linear measurements of the foot bones between the two groups revealed that metatarsal bones were the most affected by binding, and among the tarsal bones, the talar trochlea and calcaneal dimensions were most impacted. This small group of skeletons reveals that some elite women in Shaanxi apparently still did not practice foot binding in the late Ming dynasty, or practiced a much milder form of foot binding, and that there was considerable variation even among those who did practice it.
