Peripheral quantitative computed tomography (pQCT) bone measurements in children with cystic fibrosis

Summary Background Individuals with cystic fibrosis (CF) have low bone density and increased fracture risk. Methods Cross‐sectional study investigating whole body bone mineral content (WBBMC), bone geometry and strength in 12 children with CF compared to 23 age‐ and sex‐matched controls with and without adjusting for age, height, and body composition. Results CF group had lower WBBMC than controls (P = 0.007) with larger differences at older ages (age‐by‐group, P = 0.08). CF group had decreased height (P = 0.006), a trend of lower lean mass per height (P = 0.08), and no difference in relationship between WBBMC and lean mass compared to controls (P = 0.65). Periosteal and endosteal circumferences were smaller in CF (each, P = 0.02). Positive relationships of cortical area and bone strength with age were attenuated with CF (group‐by‐age; each, P
