Onset of type 1 diabetes during bone growth period is associated with increased prevalence of bone fracture: A post-hoc analysis of a cross-sectional study.

In this single-center, cross-sectional study, we demonstrated that the prevalence of fracture was significantly higher in patients who onset type 1 diabetes during 0-4 years, and 10-14 years compared with adult-onset type 1 diabetes. We are aware that this study contains a lot of limitations including non-prospective study design and a small number of participants. However, the results of this study, if followed by a larger cohort study, could provide important insights into the increased risk of fracture in patients with type 1 diabetes, and suggest the need for attention and perhaps early intervention for patients with type 1 diabetes who developed during these periods.
