RT Journal Article SR Electronic T1 Height and Weight at Menarche and a Hypothesis of Critical Body Weights and Adolescent Events JF Science JO Science FD American Association for the Advancement of Science SP 397 OP 399 DO 10.1126/science.169.3943.397 VO 169 IS 3943 A1 Frisch, Rose E. A1 Revelle, Roger YR 1970 UL http://science.sciencemag.org/content/169/3943/397.abstract AB Height and weight at menarche were found for each subject in three longitudinal growth studies. Early and late maturing girls have menarche at the same mean weight, but late maturers are taller at menarche. Two other major events of adolescence, initiation of the weight growth spurt and maximum rate of weight gain, also occur at an invariant mean weight. The hypothesis is proposed that a critical body weight may trigger each of these adolescent events. Such an interaction would explain the secular trend to an earlier menarche.
