In the 1966-67 London County Council Survey, some 10 000 children were measured twice, on occasions one year apart. Mean single-year velocities were calculated for each successive 6-month period from age centre 5 1/2 to maturity, for height, weight, upper arm and calf circumferences and triceps and subscapular skinfolds. The velocity curves, in which successive points are independently ascertained, were examined for evidence of a mid-growth spurt. In weight and limb circumferences there was a clear increase of velocity occurring from about 6 1/2 to 7 1/2 in girls and from 7 to 8 in boys. From the end of the mid-growth spurt to the beginning of the adolescent spurt, about three years later, weight velocity remained constant, but limb circumferences velocities mostly dropped. All or most of these changes in velocity can be accounted for by changes in rate of fat deposition. Girls showed no evidence of a mid-growth spurt in height, but boys had a diminution of deceleration, or relative spurt, from about 6 to about 7. These results could be accounted for if some, but not all, individual children have mid-growth height spurts. Graphs of the single-year actual-increment medians show slight differences from the standard population velocity medians, the actual-increment curves being a little more complicated than the smoothed standards.
在1966 - 1967年伦敦郡议会的调查中，约10000名儿童接受了两次测量，测量时间间隔为一年。计算了从5岁半到成年期每个连续6个月时间段的平均单年生长速度，包括身高、体重、上臂和小腿周长以及肱三头肌和肩胛下皮褶厚度。对这些速度曲线（其中连续的点是独立确定的）进行了检查，以寻找生长中期快速增长的证据。在体重和肢体周长方面，女孩大约在6岁半到7岁半、男孩在7岁到8岁时速度明显增加。从生长中期快速增长结束到大约三年后的青春期快速增长开始，体重速度保持不变，但肢体周长速度大多下降。所有或大部分这些速度变化都可以用脂肪沉积速率的变化来解释。女孩在身高方面没有显示出生长中期快速增长的证据，但男孩从大约6岁到大约7岁有减速的减小或相对快速增长。如果部分而非全部个体儿童有生长中期身高快速增长，那么这些结果就可以得到解释。单年实际增长中位数的图表与标准人群速度中位数略有不同，实际增长曲线比平滑后的标准曲线略复杂一些。
