The average maxima of heights and weights are taken by
selecting the shortest and lightest scholar in any particular group
for each school and taking the average of the figures so obtained.
The average maxima heights and weights are also obtained in the
same way.
During the peri0d of growth from 5 years to 8 years the boys
gained on the average 13.1 lbs. in weight and 6.5 inches in height.
The girls gained 12.9 lbs. in weight and 6.7 inches in height. From
8 years to 12 years the corresponding gains are 21.4 lbs. for boys
and 24.7 lbs. for girls; 6.0 inches for boys and 7.5 inches for girls.
During the peri0d of growth from 5 years until the end of the
12th year the boys increased by 12.5 inches in height and 34.5 lbs.
in weight; the girls increased 14.2 inches in height and 37.6 lbs.
in weight.
These figures show, taking into consideration the successive
groups of children examined year by year, a significant constancy.
Graphic comparison with the average increase in weight of London
County Council school children over the school period, shows that
the Croydon children follow an almost identical curve.
Heart and Circulatory System.
At routine medical inspections among the Entrant group 84
boys and 64 girls were found to have organic disease. In the Intermediate
group, the figures were 78 boys and 56 girls, and in the
Leaver group 59 boys and 44 girls. Functional disease was found
in 51 boys and 43 girls in the Entrants; 84 boys and 82 girls in
the Intermediate; 100 boys and 43 girls in the Leaver group.
Anæmia was present in 43 boys and 43 girls in the Entrant group;
43 boys and 23 girls in the Intermediate; and 33 boys and 18 girls
in the Leavers.
The percentage of all Heart and Circulatory defects among
children examined at routine medical inspection was 13.6, a small
increase on 1935.
Chest Complaints (Other than Tuberculosis).
In all the groups combined 5.4 per cent. of the boys and 4.3
per cent. of the pills had some minor affection of the lungs. This
was usually a mild Bronchitis.
Tuberculosis.
Forty-six children were referred to the Tuberculosis Officer for
further examination. One case was diagnosed as definitely tuberculous
on further examination.
