Data on age at menarche have been collected using status quo method among 230 Assamese girls and 223 Bengali girls of Guwahati (Assam) attending School. The median age, estimated by probits, is 12.45 ± 0.02 year among Assamese girls and 12.25 ± 0.03 year among the Bengali girls, respectively. However the difference (t=6.49) is found to be statistically significant (P<0.0l). Age at menarche in r...

A total of 578 adolescent girls of ten junior high schools in five educational districts of Mashhad, participated in a cros...

BACKGROUND Although it has been demonstrated that the peak height velocity (PHV) is a predictive factor of progression in adolescent idiopathic scoliosis (AIS), little is known about the usefulness of angle progression in clinical practice. The purpose of this study was to establish a relationship between height and angle velocities, as well as to determine if peak angle velocity (PAV) occurs a...
