Abstract
It is generally assumed that HV and BA correlates well with chronological age (CA). 83 girls aged 9.9 ± 0.3 yrs and 58 aged 6.9 ± 0.3 yrs as well as 79 boys aged 10.9 ± 0.2 yrs and 71 aged 7.9 ± 0.3 yrs were followed longitudinally during 5.1 ± 1.4 and 4.6 ± 1.4 yrs, respectively. Heights, bone ages (determined by two independent observers, by the method of Greulich & Pyle, using the score system) were recorded every 6 months.
In girls, 105 of them presented a peak HV of 8.6 ± 1.2 cm/yr (mean ± 1 SD) at a mean CA of 11.8 ±0.8 yrs. Mean BA was 12.2 ±0.8 yrs. Mean peak HV for bone age was 8.2 ± 1.6 cm/yr. In advanced puberty, peak HV occuring before CA=10.6 yrs (−1.5 SD for age), mean peak HV was 8.8 ± 1.1 cm/yr for CA, mean BA was 11.9 ± 0.8 yrs, 1.3 ± 0.8 yrs in advance for CA. In retarded puberty, peak HV occuring after CA=13.0 yrs (+1.5 SD), mean peak HV was 7.9 ± 1.1 cm/yr for CA, mean BA was 12.2 ± 0.8 yrs, 0.8 ± 0.8 yrs delayed.
In boys, 70 of them presented a peak HV of 10.0 ± 1.2 cm/yr at a mean CA of 13.9 ± 1.1 yrs and a mean BA of 13.4 ± 0.8 yrs. Mean peak HV for bone age 10.8 ± 2.4 cm/yr. In advanced puberty, peak HV occuring before CA=12.8 yrs (−1.5 SD for age), mean peak HV was 11.0± 1.2 cm/yr and 10.8 ± 2.4 cm/yr for a mean BA of 13.5 ± 0.8 yrs 1.2 ± 0.5 yrs in advance for CA. In retarded puberty, mean peak HV occuring at 15.7 ± 0.6 yrs (+1.5 SD for age), mean peak HV was 9.5 ± 1.9 cm/yr, mean BA was 13.6 ± 0.9 yrs, 1.5 + 0.7 yrs delayed for CA. In both sexes, mean peak HV for BA was similar for all the groups.
In total, there is a good agreement between CA and BA in normal puberty. Peak HV decreases with CA. Because of discrepancies for HV between CA and BA in advanced and in delayed puberty, it is suggested that evaluation of HV in pubertal children during growth treatment be made in relation to BA rather than CA.
