[Growth related to menarche in women of middle and low socioeconomic status]

Growth after menarche is described in 149 six to twenty year old girls from a growth and development follow-up study in a northern suburb of Santiago. Mean height at menarche and final adult height were obtained. The mean post-menarche growth was 6.40 +/- 2.70 cm. There was a large dispersion in post-menarche growth; three of them grew more than 15 cm and one 22 cm. We conclude that prediction of post-menarche growth is uncertain.
