A Norwegian study has established that men with type 1 diabetes are more likely to suffer bone fractures because of lower bone density, poorer bone quality and a lower rate of bone growth.
The study results were announced today by Astrid Kamilla Stunes and Unni Syversen of the Norwegian University of Science and Technology, Trondheim, at ECTS 2017, the 44th European Calcified Tissue Society Congress being held in Salzburg, Austria.
Dr Stunes said: "Our aim was to investigate the quality and density of bones in men with type 1 diabetes mellitus. We studied 33 men aged 20-63 with the diabetes and, for comparison, 28 healthy men of comparable age.
"Compared to the healthy men, we found, using X-ray and other tools, that men with type 1 diabetes displayed lower bone density across the whole body, together with more frequent bone disease, such as preosteoporosis and osteoporosis, at their hips. They also had a lower trabecular bone score - this is a measure of bone microarchitecture that, alongside bone density, is a good predictor of fracture risk. And their bones had significantly lower mechanical strength.
"These findings were supported by blood samples, which also confirmed that there were no significant differences between those with diabetes and the healthy men in levels of calcium, parathyroid hormone or vitamin D3, which are often associated with bone disease."
Dr Stunes summarised: "Our findings strongly support the conclusion that there is a direct association in men between type 1 diabetes mellitus and an increased likelihood of bone fractures, which might be explained by impaired bone quality and decreased bone density."
