Abstract
Positive correlations for bone mineral content BMC between 10 and 17 years of age were found for boys and girls after adjusting for body size puberty and diet This tracking of BMC indicated that osteoporosis prevention should begin already in prepubertyPrevious studies indicate that BMC is tracking during growth but it remains unclear whether this would remain significant after adjusting for important confounders We tested the hypothesis that BMC and bone area BA track from 10 to 17 years of age independently of body size pubertal stage and dietary intake of energy calcium and proteinA longitudinal study where whole body T and lumbar spine LS BMC and BA dualenergy Xray absorptiometry and dietary intake 7day food records were assessed at 10 and 17 years of age in boys and girls n = 91 Tracking of bone variables from 10 to 17 years was estimated by Pearson’s correlations adjusted for the selected confoundersThe unadjusted correlations for TBMC between 10 and 17 years likewise for LSBMC and TBA were positive for both sexes 051–081 P 00001 and remained significant after correcting for the selected confounders The unadjusted correlations for LSBA between 10 and 17 years were significant only for girls 029 P 005 but not after further corrections
