Adolescent growth in main somatometric traits of Japanese boys: Ogi longitudinal growth study
Skeletal maturity of Japanese children in Amami-Oshima Island
This report describes the TW-2 skeletal maturity status of 723 Japanese children aged 7-16 years old in Naze, Amami-Oshima Island (southern island in Japan). Naze children showed retarded skeletal maturity scores under the age of 12 years for boys and eight years for girls, and thereafter they were advanced in relation to the British standard. In the comparison with Western Kyushu children Naze boys showed almost similar RUS maturity score throug…
Skeletal maturity of Japanese children in Western Kyushu
This paper describes the skeletal maturity status of Japanese children in Western Kyushu and its variation within Japanese populations. Hand‐wrist skeletal maturity was assessed by the Tanner‐Whitehouse (1975) (TW2) method from radiographs of 500 boys and 485 girls aged from 4 to 15 years. Western Kyushu children showed retarded skeletal maturity scores (RUS, carpals, and 20‐bone) under the age of 12 years for boys and 10 years for girls, and the…
Age differences in Principal Component Analysis for Physique and Body Build Indices of School Children
For comparing the pattern of interrelationship of seven anthropometric measurements and eight body build indices in the different phase of growth, principal component analysis was applied to each of ten cohorts of three-year age range consisting of 7-18 years old school children of Nase City. The loading patterns of component I indicating body size started to change at the time corresponding to adolescent growth spurt. Rohrer index, Livi index, p…
Indices of Body Build in Children: Evaluation by Using Principal Components Analysis on Cross-sectional Data
For revealing the character of various indices of body build in children, variable sets of seven anthropometric measurements and eight indices for 474 boys and girls 7-18 years in age inhabiting Nase City were investigated with principal components analysis. With a negligible difference by sex, three components accounting for over 90% of total variance were extracted, which was interpreted to indicate respectively body size, body build and skinfo…
Association of weights of some organs during the prenatal period
The change of proportion of organ weights for the liver, intestines, lung, kidney, thymus, heart and spleen were analysed for 33 Japanese fetuses (sexes combined) by multivariate allometry. The thymus showed the highest allometric coefficient, and the spleen the next highest. The intestines, heart, liver, kidney showed medium coefficients, and the lung had the lowest
Principal component analysis of the elongation of metacarpal and phalangeal bones
A hypothesis that the first principal component computed from the covariance matrix of logarithms reflected the specific growth rates of corresponding bones was taken to analyze the growth pattern of the tubular bones of the hand. The total length of 19 tubular bones of the right hand was measured on standardized radiographs of Japanese children (33 boys, 33 girls). Metacarpals in boys and bones of the fifth digit in girls showed higher growth co…
Allometry in Metacarpals and Phalanges Analyzed by Graph Theory
Radiographic data of 47 boys and 42 girls were used to analyze the allometry system of the metacarpal and phalangeal bones in terms of “ graph theory ”. The degree of complete isometry and the clique in which component bones were in isometric relations were obtained from 19 × 19 equilibrium constant (α). The growth pattern of the middle phalanx of the fifth finger was quite different from that of other bones, and this fact coincides with the inci…
Radiogrammetric Study on the Allometry of Human Digits
The new idea of "complete isometry" was introduced to study the intercorrelation of the allometric growth of the human pentadactylism. Complete isometry is obtained from both primary and inverse allometric functions and means that two characters studied grow, in a statistical sense, at a completely proportional pace It was manifested that the growth pattern of human digits was grouped into axial and marginal, and the group of the marginal digits …
