Seen but not heard: Reconstructing the early life history of the Industrial child through carbon and nitrogen stable isotope analysis of dentine collagen

Objective This project reconstructs the early life history of the child in industrial London using incremental dentine analysis of both adults (survivors) and children (non-survivors) within a single 19th century London burial population to investigate the effects which changing social and economic conditions during Industrialisation had on their diet, health, and quality of life. Materials & Methods Macroscopic analysis was performed on the excavated assemblage (n=514) of New Bunhill Fields burial ground, Southwark, London (1821-53) to identify those with skeletal evidence of childhood stress (LEH, rickets, residual rickets) who were suitable for isotopic analysis. Radiographic analysis of the dental pulp chamber was also performed on these individuals to identify childhood vitamin D deficiency. A total of 20 adults (20/157) and 22 non-adults (22/357) were chosen for carbon (δ13C) and nitrogen (δ15N) stable isotope analysis. Incremental dentine analysis was performed on the first permanent molar and isotopic profiles were created spanning from birth until tooth completion/death during tooth development. Results The isotopic data indicated that adult and non-adult diet was consistent with that observed in other 19th century London burial populations. Evidence for breastfeeding was widespread amongst survivors and non-survivors. Radiographic results indicated that vitamin D deficiency during early childhood was much more prevalent within the burial group than skeletal evidence suggested, and it was observed more frequently in those who survived into adulthood (80%) than in those who died during childhood (42%). Concurrent evidence of isotopic physiological stress with LEH formation was observed in some but not all individuals. A pattern of opposing co-variance was observed often in early infancy, most frequently in non-survivors, and isotopic evidence for physiological stress was also observed in the final dentine increments of some who died during tooth development. There was a tentative association observed between adult age-at-death and skeletal stress indicators in early childhood, where the average age-at-death was older in those with fewer childhood stress indicators. Conclusions & Significance This research project found that early life stress was common within this urban community and was associated with negative outcomes later in life, especially amongst those who died in childhood.
