Metabolic Deficiencies Found Among Migrant Settlers in Colonial Australia
In one of the first studies of its kind, Australian researchers have researched the health and economic status of a collection of migrant settlers to colonial South Australia from an evaluation of skeletal remains at the Anglican Parish of St Mary’s in Adelaide.
The brand-new study, released in reputed international publication PLOS ONE today, is the only bio-archaeological research examining evidence of modifications in the teeth and bones of European settlers in the St Mary’s- on-Sturt area to acquire new insights into the health and living conditions they dealt with in the new colony.
At the demand of the parish, the long-running research started at St Mary’s Cemetery 20 years ago when Flinders University archaeologists excavated a rear section of the cemetery which did not have any kind of markers.
Based on follow-up research studies by Flinders, University of Adelaide, and international experts in bioanthropology, anatomy, and dental development have used anatomical and micro-CT techniques to this distinct archaeological sample.
The non-custodial British colony of South Australia, established in 1836, provided fresh hope of a greater life to the migrants than they might have experienced in Britain.
Where were the remains of the migrant settlers?
This assembly of early settlers buried in a section of St Mary’s Anglican Church Cemetery between 1847 and 1927 was assigned for government-funded burials. It was fascinating to investigate abnormal manifestations related to metabolic deficiencies.
The findings suggest that the majority of these abnormalities were the result of poor diets in the new colony. Abnormal indicators seen in these bones were associated with vitamins C and D and iron deficiencies.
In contrast to similar released data from two other 19th century British cemeteries – St Martin’s, Birmingham, and St Peter’s, Wolverhampton – the occurrence of vitamin C deficiency was a lot more in the St Mary’s example, which of vitamin D deficiency was much less, indicating the prevalence of sunlight in South Australia.
The research study showed that most of the modifications occurred during the last half of the individuals’ life Changes detected in teeth, specifically developmental defects, showed that some people experienced health stresses during the fetal and first 25 years of the postnatal life.
Differences in socio-economic status
The place of burials at St Mary’s Cemetery from the mid-1840s to 1860s showed differences in the economic status of migrants.
A decline in the number of burials in the ‘free ground’ area of the cemetery from the 1870s showed improvements in the local economy and the ensuing economic recovery of the colony.
Senior author and team leader Emeritus Professor Maciej Henneberg claims the discoveries highlight the unpreparedness of the new colony for the settlement of the first migrants and the consequences of living circumstances on the new arrivals.
The rare skeletal sample from the totally free ground of St Mary’s Anglican Church generates a possibility to comprehend the effects of the establishment of the new colony on the health of said migrant settlers, says co-author Flinders Professor Donald Pate, that was involved in the St Mary’s archaeological excavations.
” This body of work broadens the understanding of the effects of early industrial colonization on migrant health.”
Conditions bettered from the 1870s to 1920s when the number of burials reduced, indicating a progressive improvement in the economic status of migrants – a pattern echoed across the rest of the colony, researchers claim.
