In the present study, the change in BMI with age was examined by applying the wavelet interpolation method (WIM), and the maximum peak velocity (MPV) of BMI was derived from the growth (aging) distance curve of BMI. We investigated the association between the age at menarche and MPV of BMI. In Addition, the critical period for body fat mass at the occurrence of menarche was estimated. Data were obtained from 87 female non-athletes in their third year at high school in the Tokai area. Health examination records showing these subjects'heights and weights from the first grade of elementary school to the final year of high school (1990-2002) were collected and BMI was calculated for each grade. Ages at menarche were ascertained from questionnaires. The age at MPV of BMI (12.19±1.35 years old) was almost the same as the age at menarche (12.11±1.09 years old). And there was no difference between the frequency distribution of age at menarche and at MPV of BMI. Therefore, the age at MPV of BMI is estimated to be the critical period for body fat mass at the occurrence of menarche. By applying a regression equation (y=1.394x-15.630) of the age at menarche to the age at MPV of BMI, we could estimate the critical period for body fat mass {(10.84±3.58kg)∼(11.53±3.81kg)} at the age of menarche and at MPV of BMI.
