This work concentratedon an area of England with a high concentration of immigrant populationfrom the Asian subcontinent. It is important to know that most of thesepeople have lived in this same locality and data was collected using severalsources, all of which had been established for a long time and not justspecifically to monitor Asian children. It appears that full ascertainmentwas achieved in this study and a threefold increase noted over just 10years was a reliable data. Cultural adoption was investigated in some detail and it was found thatdiabetic children had adapted to the English culture much better than theirnon-diabetic peers. Based on this observation, it seems that children ofAsian origin may have the genetic predisposition to develop IDDM if exposedto the same environment as their peers in Europe.
Lazio population has a lower incidenceof diabetes than Sardinia.
In this study, details of children with IDDMborn to both Sardinian parents or one Sardinian parent, were compared toLazio born parents. They found that children with one Sardinian parenthad a rate half that of Sardinia and double that of the indigenous population. This study emphasizes the role of genetic predisposition since there wasno significant need for cultural adaptation. Their conclusion was thatgenetic susceptibility determines the frequency of IDDM in response tothe environment. This study was conducted in the same area where Bodansky did hisoriginal work on the immigrant population.
