Abstract: This study was designed to analyse the various affection factors on menarche of Chinese Han adolescent girls. 32,256 subjects aged 10-18 from the rural areas of 29 Chinese provinces took part in this study. In total there were 29 measures which could be divided into three fields: geographic-climate, socio-economic and growth-development. At first, several factors were extracted separately from these fields by using varimax factor analysis. Then the 29 samples of girls were divided into two groups according to their means of menarche, and canonical discriminant analysis was done by using all the factors as dependent variables. According to the discriminant result, several factors which were thought to be important in affecting the menarcheal age of Chinese rural adolescent girls were determined, and further comparisons were done between these two groups. The results of this study will help to design the interfering strategies in improving Chinese rural girls adolescent development.
