男子における身長発育のパターンに関する検討 : velocity curveからの分析

Abstract

Pattren of height growth has been studied in twelve years of longitudinal data of standing height; ages from 6 to 17 years of high school boys (231 boys) who were grouped according to their peak height velocity ages (PHV ages) into 5 groups for boys. A method of analysis in longitudinal data of standing height is described the characteristic of distance and velocity curves grouped according to PHV ages. It was found that grand mean PHV age was 11.94 years from distribution of sample size according to PHV ages. Premature groups were shown that standing height was high from 6 to adolescent growth, and was low in final standing height on the characteristic of distance curves. It was indicated that velocity curves of 5 PHV age groups was pattern of single peaked height velocity. The earlier occurance of peak height velocity is associated with a larger magnitude of the peak height gain and the amount of adolescent growth spurt.
