Resumen:
The most conspicuous and unequivocal characteristic from the female sexual maturation is the menarche. This event has been profusely investigated, however in many populations we do not have updated information about the age of occurrence and the changes associated with the size and body composition. The aim of the present study was to analyze the incidence of the menarche in growth and body composition from girls from La Plata city, Buenos Aires province. In a sample of 1291 students aged from 8 to 16 years old were relevated the menarche presence and the following anthropometric variables: body weight, total and sitting heights, tricipital and subscapular skinfolds and were calculated indexes of body mass (BMI) and subscapular tricipital (STI) and upper arm fat and muscle areas. In the 34.2% of the evaluated girls was present the menarche distributed between 10 and 16 years old at the mean age of 12.6 years old which was calculated by the status quo method. Sample was divided by menarche and chronological age into two developmental groups. Descriptive parameters were estimated in each group and were compared by ANOVA or Kruskall Wallis Tests in accord to the variables distribution normality. Both maturative groups were significantly differents in the majority of relevated and calculated variables. In relation to the developmental event is possible to conclude that a) the menarche mean age was not different with respect to the previous national data reports and b) the menarche is a powerful discriminant factor for the intrapopulational growth and development.
