Tempo-unconditional 1-year bone score velocities in well-off north-west Indian children

Tempo-unconditional 1-year bone maturity score velocities in well-off 6-16 year-old North-west Indian children from Chandigarh (245 boys and 238 girls) are presented for the first time using the TW2 system. Rater's replicability/comparability was high. The peak RUS bone maturity score velocity is reached at 13 years in girls and at 15 years in boys, maintaining a standard 2-year difference. Velocities of the three bone maturity scores are relatively larger, but their respective standard deviations are smaller than those reported for American whites and blacks. North-west Indian children seem to be maturing faster than the British standards.
