Research Abstract	The aim of the study was to elucidate the effect of prenatal and/or postnatal status on calcaneus bone density in adolescents. We recruited 1,143 adolescents (501 males and 642 females) with mean age of 14.8±1.8 years in a junior high school and a high school, and recorded their anthropometric data. Bone density was measured using an ultrasound bone densitometer (A-1000 Express, Lunar). Prenatal and postnatal statuses were estimated using their maternity health record books. High neonatal weight gain at 1 month was significantly associated with high calcaneus bone density in adolescents from a logistic regression analysis including above prenatal and postnatal factors (p=0.042).
