The menarcheal age of Chinese girls was analysed based on a national survey in 1985. A total of 162,902 girls, aged 7-22 years, of Han nationality and 34,232 girls, aged 7-18, of 27 minority nationalities were sampled. Data were further subdivided into urban and rural areas. It was found that the curves of menstruating percentage in each of the subgroup were in long sigmoid shapes. The menstruating rate (MR) of Han girls was higher than that of the minority girls in almost every age group. The median menarcheal age (MMA) of Han girls was significantly lower than that of the minority girls. In Han nationality the urban girls showed higher MR and lower MMA than the rural girls. The influence of hereditary, cultural and economical factors on menarcheal age in Chinese girls is discussed. The data of this study were also compared with research reports from other world literature.
