Asynchrony between the rates of standing height gain and bone mass accumulation during puberty.

摘要: During puberty, the marked increases in both standing height and bone mass appear to be dissociated time, former occurring earlier than latter. However, age or pubertal stage at which this dissociation is maximal girls as opposed boys, whether similar all parts of skeleton, are not clearly established. Standing mineral mass, assessed by measuring areal density (BMD), levels lumbar spine, femoral neck midfemoral shaft, were measured 98 females 100 males between ages 9 19 years twice a 1-year interval. In males, greatest difference BMD gains occurred 13–14 year group was more pronounced for spine shaft. females, detectable younger (11–12 group) appeared lower magnitude males. genders, during period peak velocity, corresponded stages P2-P3. Such rates statural growth accrual could define state relatively low contribute higher incidence fracture known occur and/or when maximal.
