Aim: To study the association between femoral neck (FN) bone mineral density (BMD) T‐score and fracture risk in individuals with and without type 2 diabetes (T2D). Materials and Methods: We performed a single‐centre retrospective cohort study using the Danish National Health Service. BMD of the FN was measured by dual‐energy X‐ray absorptiometry. Cox proportional hazards regression models were used to study the association between FN BMD T‐score and fractures in individuals with and without T2D separately, adjusted for age, comorbidities and comedication. The results from this analysis were used to estimate the 10‐year absolute fracture risk. Results: In total, there were 35,129 women (2362 with T2D) and 7069 men (758 with T2D). The FN BMD T‐score was significantly associated with risk of any, hip and major osteoporotic fracture in men and women with [adjusted hazard risk ratios (aHR) women, hip: 1.57; 95% confidence interval (CI) 1.24–2.00, incidence rate (IR) 8.7; aHR men, hip: 1.55; 95% CI 1.01–2.36, IR 4.6] and without T2D (aHR women, hip: 1.75; 95% CI 1.64–1.87, IR 7.0; aHR men, hip: 1.97, 95% CI 1.73–2.25, IR 6.3), and its ability to predict fracture risk was similar. Fracture IRs were not significantly different for individuals with or without T2D, nor was the estimated cumulative 10‐year fracture risk. Conclusions: The FN BMD T‐score was significantly associated with hip, non‐spine and major osteoporotic fracture risk in men and women with and without T2D. Fracture risk for a given T‐score and age was equal in individuals with and without T2D, as was the ability of the FN BMD T‐score to predict fracture risk. [ABSTRACT FROM AUTHOR]

Aim: To determine the association of diabetes-related characteristics with fractures at different sites in individuals with type 2 diabetes (T2D)., Materials and Methods: We conducted a cohort study using the Clinical Practice Research Datalink (CPRD) GOLD. Patients aged over 30 years with T2D were identified within the CPRD. Patients were followed from the start of diabetes treatment until the end of data collection, death, or the occurrence of a fracture. Cox proportional hazards models were used to estimate the hazard ratios for the association of the individual characteristics (diabetes duration, glycated haemoglobin [HbA1c] level, and microvascular complications) with fracture risk, adjusted for demographics, comorbidities and comedication., Results: A diabetes duration of >10 years was associated with an increased risk of any fracture and major osteoporotic fractures (MOFs), while a diabetes duration of >8 years was associated with an increased hip fracture risk, compared to a duration <2 years. An HbA1c level <6% was associated with an increased fracture risk compared to HbA1c values of 6% to <7%. The presence of one or two microvascular complications was associated with an increased risk of any fracture and MOFs and the presence of two microvascular complications was associated with an increased hip fracture risk, compared to no microvascular complications., Conclusion: In conclusion, our study shows that a diabetes duration of 10 years or more, strict glycaemic control resulting in HbA1c levels below 6%, and/or the presence of at least one microvascular complication increased the risk of any fracture, hip fractures, MOFs, and humerus fractures, but not ankle, scapula or skull fractures., (© 2024 The Author(s).

Type 2 diabetes (T2D) is a prevalent disease and has been associated with an increased fracture risk despite normal or even higher areal BMD. The aim of this study was to estimate the association between glucose metabolism status (GMS) and measurements of glycemic control with HRpQCT parameters of bone microarchitecture and strength. Participants of the Maastricht study who underwent an HRpQCT scan at the distal radius and tibia were included. GMS was determined by use of an oral glucose tolerance test and grouped into a normal glucose metabolism (NGM), prediabetes, or T2D. Linear regression models were used, stratified by sex with multiple adjustments. This study incorporated cross-sectional data from 1400 (796 [56.9%] NGM, 228 [16.3%] prediabetes, and 376 [26.9%] T2D) men and 1415 (1014 [71.7%] NGM, 211 [14.9%] prediabetes, and 190 [13.4%] T2D) women. The mean age was 59.8 ± 8.6 and 57.6 ± 9.0 yr for men and women, respectively. After adjustment, T2D was associated with a higher total BMD measured by HRpQCT and cortical thickness, and a smaller total and trabecular area in men and women compared with NGM. In women, T2D was additionally associated with a higher stiffness and failure load at the radius. Results were more pronounced at the distal radius than at the distal tibia. To conclude, these findings suggest that in this cohort of Maastricht study participants, total and trabecular bone area are smaller, but bone microarchitecture, density, and bone strength assessed by HRpQCT are not impaired in individuals with T2D., Competing Interests: Peter Vestergaard is head of research in the Steno Diabetes Center North Denmark sponsored by the Novo Nordisk Foundation.
