The median age at menarche observed by status-quo methods in 1991, and calculated by mean of probit analysis in a sample of 239 school girls from Marrakesh aged 11-17 years, was 13.75 +/- 0.17 years. Compared w ith earlier observations obtained for Moroccan girls in 1982 and 1987 the results show a decline of age at menarche of 0.55 year in the peri od 1982-91 and 0.25 year in the period 1987-91.
