from 12.3 (Hyderabad) to 13.2 years (Varanasi), from 13.3
(Hyderabad and Vellore urban slum) to 14.1 years (Varanasi)
and from 13.9 (Vellore urban slum) to 14.8 years (Jabalpur
and Delhi urban slum) respectively (Table 34).
The mean weight of girls at reaching stage II, III, IV and
V was between 24.8 (hyderabad) to 26.9 (Chandigarh), 28.5
(Hyderabad) to 32.0 (Chandigarh), 32.9 (Hyderabad) to 37.8
(Varanasi) and between 39.8 (vellore urban slum) to 44.0 (Varanasi)
kg. respectively at different centres (Table 35). The mean
height of girls at stage II, III, IV and V of breast development
varied between 133.0 (Varanasi) to 136.2 cm. (Chandigarh),
139.3 (Hyderabad) to 143.7 cm. (Chandigarh), 145.0 (Hyderabad)
to 148.3 cm. (Chandigarh) and between 150.0 (Vellore urban
slum) to 155.5 cm. (Chandigarh) respectively (Table 36).
The average time taken from stage II to stage III, stage
III to stage IV and from stage IV to stage V of breast development
varied between 0.7 to 1.3, 0.7 to 1.1 and 0.4 to 1.2 years
respectively. The gain in weight and height from stage II
to III of breast development varied between 3.7 to 5.4 kg.
and 5.6 to 8.5 cm., from stage III to stage IV 4.4 to 6.2
kg. and 4.6 to 6.9 cm. and from stage IV to stage V 3.6 to
7.1 kg. and 3.5 to 7.2 cm. respectively (Fig. 47, 48 &49).
It was felt that along with physical and sexual development
in adolescents, skeletal maturity should also be investigated.
But only three centres viz. AIIMS, Delhi; Medical College,
Jabalpur and Christian Medical College, Vellore (urban) had
adequate facilities and agreed to carry out this component
of the study. In view of the facilities and expertise available,
Vellore centre, on a request from the Council, coordinated
this component of the study.
The means and standard deviations of skeletal maturity scores
and bone ages considering gender and chronological age of
the study children separately for each centre are shown in
Tables 37 to 39 and percentile values of skeletal maturity
scores for these centres are given in Tables 40 to 42.
As far as Vellore children are considered the boys lag behind
by one year in Carpal bone maturity at each of the chronological
ages considered, whereas this was limited to 6 months in Radius,
Ulna and Short bone maturity. On the contrary, girls are one
year ahead in their RUS (Radius, Ulna, Short) bone maturity
compared to their chronological ages till 12.5 years, after
which they level off. However, they lag six months behind
in their carpal bone maturity till the age of 12 and reached
total maturity by the age of 13 years. As the 20 bone maturity
score takes into account,
