Previous traumatic brain injury is associated with an increased odds for gestational diabetes: a nationwide register-based cohort study in finland.

Aims: Despite recent findings that traumatic brain injury (TBI) is a possible risk factor for type 2 diabetes (DM2) and that a strong association exists between gestational diabetes (GDM) and the risk for the development of DM2, no previous studies have investigated the effects of TBI on the risk for the development of GDM. Therefore, this study aims to determine the possible association between a previous traumatic brain injury and later gestational diabetes.

Methods: In this retrospective register-based cohort study, data from the National Medical Birth Register were combined with data from the Care Register for Health Care.
