THE PROMISE STUDY 

This research study is called ‘PRenatal and Obstetric Maternal Exposures and ISlet Autoantibodies in Early Life:  The PROMISE Study'.  The purpose of this study is to find out more about how exposures during pregnancy, such as having an infection, diet and growth may impact later risk of type 1 diabetes (TID) and islet autoimmunity in the child.  We are also interested in finding out more about why having a father or sibling with T1D increases risk of autoimmunity in the child more than having a mother with T1D.
