Abstract

Context: Fracture risk in people with type 1 diabetes (T1D) is higher than their peers without diabetes. Objective: To compare bone mineral density (BMD) across the lifespan in individuals with T1D and age-and sex-matched healthy controls. Design: Cross-sectional. Setting: Subjects (5-71 years) with T1D and matched controls from ongoing research studies at Barbara Davis Center for Diabetes. Patients or other participants: Participants with lumbar spine BMD by dual X-ray absorptiometry (DXA) were divided into 2 groups: children ≤20 years and adults >20 years. Intervention: None. Main outcome measures: Comparison of BMD by diabetes status across age groups and sex using a linear least squares model adjusted for age and body mass index (body mass index (BMI) for adults; and BMI z-score in children). Results: Lumbar spine BMD from 194 patients with T1D and 156 controls were analyzed. There was no difference in age-and BMI-adjusted lumbar spine BMD between patients with T1D and controls: among male children (least squares mean ± standard error of the mean [LSM ± SEM]; 0.80 ± 0.01 vs 0.80 ± 0.02 g/cm2, P =. 98) or adults (1.01 ± 0.03 vs 1.01 ± 0.03 g/cm2, P =. 95), and female children (0.78 ± 0.02 vs 0.81 ± 0.02 g/cm2, P =. 23) or adults (0.98 ± 0.02 vs 1.01 ± 0.02 g/cm2, P =. 19). Lumbar spine (0.98 ± 0.02 vs 1.04 ± 0.02 g/cm2, P =. 05), femoral neck (0.71 ± 0.02 vs 0.79 ± 0.02 g/cm2, P =. 003), and total hip (0.84 ± 0.02 vs 0.91 ± 0.02, P =. 005) BMD was lower among postmenopausal women with T1D than postmenopausal women without diabetes. Conclusion: Across age groups, lumbar spine BMD was similar in patients with T1D compared with age-and sex-matched participants without diabetes, except postmenopausal females with T1D had lower lumbar spine, femoral neck, and total hip BMD.
