Rate of bone mineral accrual
Tidsramme: 0, 12, 24 months
|
Bone mineral mass and density will be measured by dual-energy x-ray absorptiometry (DXA) at baseline and 12 months.
Percent change over time will be calculated and then compared in subjects with type 1 diabetes and matched control subjects.

Cross-sectional comparison of bone microarchitectural parameters in patients with diabetes vs. controls
Tidsramme: Baseline
|
Bone microarchitecture will be assessed by high-resolution peripheral quantitative computed tomography (HR-pQCT).
Parameters measured will include cortical compartment density, cortical thickness, cortical porosity, trabecular density, trabecular number, and trabecular thickness.

Bone microarchitecture will be assessed by high-resolution peripheral quantitative computed tomography (HR-pQCT) at 0 and 12 months.
Parameters measured will include cortical compartment density, cortical thickness, cortical porosity, trabecular density, trabecular number, and trabecular thickness and percent change over 12 months will be calculated.
Percent change will be compared in patients with diabetes and matched controls.

Association of glycemic control with bone mineral accrual
Tidsramme: 0 and 24 months
|
Glycemic control will be assessed by hemoglobin A1c measurements at study visits and as part of routine diabetes care.
An average hemoglobin A1c over the time of observation will be calculated using the trapezoidal rule.
Association of glycemic control with bone mineral accrual as measured by DXA will be examined via regression analysis.

Association of bone mineral accrual with moderate-to-vigorous physical activity
Tidsramme: 0 and 24 months
|
activity will be assessed with accelerometers.
The association of bone accrual among youth with and without diabetes will be assessed by correlation analysis.
