 One study, called the Japanese American Community Diabetes Study that started in 1994 and went through 2003, involved the pro-bands taking part to test whether the increased risk of diabetes among Japanese Americans is due to the effects of Japanese Americans having a more westernized lifestyle due to the many differences between the United States of America and Japan.One of the main goals of the study was to create an archive of DNA samples which could be used to identify which diseases are more susceptible in Japanese Americans.Concerns with these studies of the risks of inherited diseases in Japanese Americans is that information pertaining to the genetic relationship may not be consistent with the reported biological family information given of Nisei second generation pro-bands.
