The study confirms the results of previous work with IVF families. This should be encouraging for families using these techniques in the future.

Prior to risk notification, the process of being screened raised concerns and expectations about future changes. Despite the lack of any evidence, people believed lifestyle changes would be effective in reducing their risk. Since the impact of lifestyle in the development of type 1 diabetes is not yet established, accurate information about the role of health behaviour in the progression to overt diabetes is needed to avoid unrealistic expectations on the benefit of these changes and unnecessary impairment to quality of life. Personally initiated changes should be monitored since they could importantly influence the progress and outcome of prevention trials.
