The gap between the accerelated physical growth and the stayed or relatively delayed mental development has become common in many countries. In this sense, the study on sexual maturation has to cover not only the physical but also the mental aspects. Age at menarche, the knowledge of sexual phenomena, and the behavioural pattern at counselling of sexual problems were the content of questionnaire. The subjects were girl students at Eiwa Junior and Senior High School in Yamanashi Prefecture. The results are summarized as follows: (1) Age at menarche has become younger annually. (2) Psychological reaction toward menarche differed dependent upon the age at it. (3) After menarche, students became more conscious to sexual phenomena, and tended to select persons other than parent as the counseller. (4) The amount of knowledge on sexual phenomena increased with the chronological age, but the understanding of underlying mechanism did not show a simply increasing pattern. (5) The age at menarche and the feeling invited by the menarche seemed to influence the increase of knowledge and the deepening of understanding. (6) By the content analysis of the answer to questionnaire, the development in intelligence was supposed to relate closely to the advancement of knowledge on sexual matters.
Measurements of physical size and the skinfold thickness of upper arm and back were performed on 2060 boys and 1895 girls of junior high schools in Numazu City. The results were as follows: (1) In boys, the mean skinfold thickness value of upper arm decreased slightly according to age, while increased in girls. (2) The mean skinfold thickness value of back increased according to age in either sex. The increase in girls was larger. (3) The mean skinfold thickness value of upper arm + back with all school grades was 14.8 ± 6.8mm in boys and 24.1 ±8.7mm in girls. The difference by age was very small in boys, while an apparently significant difference was observed in girls, comparing between 12-and 15-year-old girls. As for P50, (Pcrcentile 50) P75 and P95 of skinfold thickness of upper arm+back, the difference by age was also very small in boys. But they increased according to age in girls. Only P95 of 14-and 15-year-old children of either sex was almost similar. (4) Obesity screening was performed applying several methods as the increase rate over the standard weight of each height, Rohrer Index, skinfold thickness and Mori Index (the increase rate over the standard weight of each height x skinfold thickness). The selecting rate of obese children was almost similar in the increase rate over the standard weight of each height and skinfold thickness. (5) Muscular children could be omittd from obesity by applying Mori Index.
