[The secular trend of standing height in adolescent girls from longitudinal data].
In this study which is based on the longitudinal data aggregated from health examination records, the subjects consist of 287 girls who attended a private school in Tokyo. The subjects are divided into five groups according to birth year from 1950 to 1970 in order to find secular trend during twenty years with one-way analysis of variance. Age at Peak Height Velocity (APHV), Peak Height Velocity (PHV) and Height attained at Peak Height Velocity (HPHV) were computed in each height velocity curve derived from differential calculus of height distance curve. The result show that HPHV is gradually getting taller by year although APHV and PHV do not change. It may be considered that our subjects of the private school are girls of families in the relatively upper-middle class.
