Measures taken included stature, weight, skeletal maturity, mid-upper arm circumference, triceps and subscapular fatfolds and body-mass index. The hypothesis that hyperactive-only boys would show delayed maturation, as indicated by lower bone-age, was not confirmed. However, these boys had significantly smaller mid-upper arm circumference, triceps fatfold and body-mass index than the other groups. The results suggest that body leanness may discriminate ‘pure’ hyperactive boys from aggressive-hyperactive boys.Anthropometric data were collected on groups of seven-year-old Dunedin (New Zealand) boys, identified as hyperactive-only, aggressive-hyperactive, aggressive-only and non-aggressive/non-hyperactive.

Les mesures prises incluaient la taille, le poids, la maturité osseuse, la circonférence à la moitié supérieure du bras, les plis au triceps et en sous-scapulaire et l'indice de masse corporelle. L'hypothèse selon laquelle les garçons seulement instables présenteraient un retard de maturation indiqué par un âge osseux inférieur n'a pas été confirmée, cependant ces garçons présentment une circonférence à la moitié supérieure du bras plus faible, un index de pli du triceps et de la masse corporelle plus faible que celui des autres groupes. Les résultats suggèrent que la minceur corporelle peut aider à différencier les garçons purement instables, des garçons agressifs et instables.Développement physique des garçons instablesDes données anthropométriques ont été recueillies chez des garçons de sept ans de Dunedin (Nouvelle Zélande), identifiés comme instables seulement, instables et agressifs, agressifs seulement et non agressifs/non instables.

Die Daten beinhalteten Körperbau, Gewicht, Skelettreifung, mittleren Oberarmdurchmesser, Fettfaltenindex im Bereich des Triceps und Subscapularis, sowie Körpermassenindex. Die Hypothese, hyperaktive Jungen hätten eine verzögerte Reifung, objektiviert durch ein niedriges Knochenalter, konnte nicht bestätigt werden. Jedoch hatte diese Gruppe einen signifikant kleineren mittleren Oberarmumfang, Tricepsfettfaltenindex und Körpermassenindex. Die Ergebnisse deuten darauf hin, daß die hyperaktiven Jungen von den aggressiv-hyperaktiven durch ihren hageren Körperbau zu unterscheiden sind.Körperliche Entwicklung hyperaktiver JungenVon verschiedenen Gruppen siebenjähriger Jungen aus Dunedin, (Neu Séeland) mit der Diagnose hyperaktiv, aggressiv-hyperaktiv, aggressiv und nicht aggressiv/nicht hyperaktiv wurden anthropometrische Daten gesammelt.

Las mediciones que se realizaron fueron la estatura, peso, madurez esquelética, circunferencia de la parte media del brazo, pliegue de grasa a nivel del triceps y zona subescapular e indice de masa corporal. No se confirmó la hipótesis de que los niños sólo hiperactivos tendrían un retraso madurativo, indicado por una edad ósea mas baja. Sin embargo estos niños tenían un menor perímetro braquial, pliegue graso e índice de masa corporal que los otros grupos. Los resultados sugieren que la delgadez corporal puede discriminar los niños puramente hiperactivos de los agresivos hiperactivos.Desarrollo fisico de los muchachos hiperactivosSe recogieron los datos antropométricos de grupos de niños de siete años de edad en Dunedin (Nueva Zelanda), etiquetados como simplemente hiperactivos, agresivos-hiperactivos, agresivos sólo y no agresivos ni hiperactivos.

Dunedin children were of similar stature to American children but were about 1 cm taller than British children. Socio-economic stature (SES), birth weight and maternal stature were significantly correlated with stature, while the sex of the child, gestational age, maternal age, ordinal position of the child in the family and number of children in the family were not significantly correlated. The effect of SES in Dunedin was much less than that reported for the United Kingdom. It was concluded that in this population SES and family structural factors are probably less important as determinants of child growth than they are in Britain and are of considerably less importance than the mother's stature and the child's birth weight.

Other loci surveyed were within the range of expectation. The frequency of phosphoglucomutase type PGM was found to be 0.87, and for the dry cerumen allele 0.57. The frequency of the A allele was found to be decreasing among males, and several possibly distinctive characteristics of northern and southern Athapaskans are noted.

K is not absent though the frequency is not great (0.028). Surprising results were obtained for the MN locus (0.399 for M, 0.601 for N), P (0.209 for P1), and Lewis (0.568 for Le(a+)). A frequency of phosphoglucomutase type PGM11 of 0.890 was found; all hemoglobins were type AA; no G-6-PD deficiency was found an all were type B positive; the frequency of the dry cerumen allele was found to be 0.323.

Most of the samples were also analyzed for hemoglobin patterns and G-6-PD variants. The only significant difference in allelic frequencies between the two populations occurred at the P locus. An apparent deficit in the observed frequency of type A1, and hence a departure from equilibrium, at Upper Laird could not be tested for significance due to insufficient degrees of freedom.
