To determine whether bone characteristics in adolescents with type 1 diabetes mellitus (DM) are influenced by blood glucose regulation and disease duration. The subjects were adolescents with type 1 DM (n=55) recruited from the University of Utah's Primary Children's Pediatric Diabetes Treatment Center. A reference database consisting of 95 healthy adolescents from the same geographic area was used for comparison.Study design Measurements of the tibia by peripheral quantitative computed tomography were made to assess cortical and trabecular bone characteristics. Hip, spine, and whole body characteristics were measured by dual-energy x-ray absorptiometry. Height, weight, health histories, Tanner stage, disease duration, insulin regimen, and glycosylated hemoglobin values were recorded.


Age, maturation, and body size and composition values were similar between the subjects with type 1 DM and reference. Subjects with type 1 DM had lower tibia trabecular and femoral neck density and whole body mineral content and density. The mean glycosylated hemoglobin value was inversely related to tibia trabecular bone density (R(2)=-0.30) and whole body bone mineral content (R(2)=-0.25) and accounted for 3.0% to 8.9% of the variance.


Altered bone mineral acquisition in adolescents with type 1 DM may limit peak bone mass acquisition and increase the risk of osteoporosis in later life.
