The physical growth patterns of contemporary Japanese were analyzed using cross-sectional data of 5 heights and lengths, 6 circumferences, 2 skinfolds and body weight of 8,679 males and 8,889 females aged 7 to 20 years. Measurements were made in 1978-'79. Lower to upper portion growth gradient and head-trunk gradient were observed.The annual increment for heights and lengths reached the maximum at 12 or 13 years in males and 10 or 11 years in females, about one year later for circumferences, and two years later for skinfolds.As compared with the data obtained in 1966-'67, the adolescent growth spurt took place earlier, and the average age at menarche was 5 months younger in the present sample.During the period from 1966-'67 to 1978-'79, the values of heights, lengths and waist circumferences increased, but that of chest circumferences decreased or remained constant.The growth acceleration trends of Japanese were different from those of Americans.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations鈥揷itations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
