The mean age of menarche(13.22 years) appeared about 2.1∼2.9 years later than MGA of physique, the age at PHV(10.32 years) appeared about 0.8 years faster than the age at PHV(11.15 years) and PGCV(11.13 years). 4. As a result of ANOVA, the difference between urban area(13.07 years) and rural area(13.38 years) of menarche`s age appeared -0.31 years(p$lt;.05), the difference between urban area and rural area by items of MGA appeared not significant (p$gt;.05). 5.
