A longitudinal study on 508 girls chosen at random from the elementary schools of Turin showed that age at menarche had a Gaussian distribution. The mean age was 12.58 +/- 0.05 years. Peaks of incidence of menarche were observed in January and July-September. The correlation coefficient of mothers' (recollected) age at menarche with daughters' was 0.32.

Abstract

A longitudinal study on 508 girls chosen at random from the elementary schools of Turin showed that age at menarche had a Gaussian distribution. The mean age was 12.58 +/- 0.05 years. Peaks of incidence of menarche were observed in January and July-September. The correlation coefficient of mothers' (recollected) age at menarche with daughters' was 0.32.
