Diabetes risk after a normal oral glucose tolerance test during pregnancy.

Introduction: Our aim was to conduct a follow-up of a cohort of women screened for GDM with a normal oral glucose tolerance test (OGTT) during pregnancy to investigate the incidence and time of diagnosis of manifest diabetes mellitus and identify risk factors for subsequent development of diabetes.

Methods: This was a follow-up study of a cohort with normal and borderline OGTT in 1991/1992. Among the original 352 women, only five were lost to follow-up.
