Variation in menarcheal age according to the growth channels appertaination and the soft tissue component in pubertal girls

Growth channels phenomena in pubescence girls (aged 11, 5 to 14, 5 years) were used as a basis for a detailed analysis of the relation between the soft tissue growth component (related to growth channels) and menarcheal experience. The soft tissue component showed statistically significant differences between the growth channels (in all groups and at all time points). Generally it was shown that girls from the second growth channel (soft rounded physique) were the first to experience menarche (19% of them at the age of 11, 5 years), and the first to complete it (100% at the age of 14, 5 years). The first growth channel girls (elongated body shape) matured with some latency, compared to the second group during the first two years, however 97% of them got their first menstrual flow by the age of 14, 5 years. In the third growth channel (short and thin body shape girls), menarche appeared with a marked latency, and only 5% had menarche at the age of 12, 5, while 43% had it at the age of 13, 5, and 955 at the age of 14, 5 years. These data support the proposition that sexual maturation stages follow the specificity of the type of physique in pubescence girls.
