Abstract
We estimated age at menarche in a cross-sectional sample of 159 competitive figure skaters aged 11-22 years. The sample represented three standards (test stream, pre-elite, elite) and three disciplines (free skaters, pair skaters, dancers). The status quo (yes/no) and retrospective methods were used. Estimated age at menarche based on probit analysis of the status quo data was 14.2 +/- 0.5 years, with 95% confidence intervals of 13.2 to 15.2 years. Mean recalled age at menarche for 67 skaters aged 16 years or over was 13.6 +/- 1.2 years. Comparisons of skaters by standard and discipline were limited to skaters ≥16 years. Menarche was, on average, significantly later (P<0.01) in elite (n = 36; 14.0 +/- 1.4 years) than in test stream (n = 15; 12.9 +/- 0.8 years) skaters. Age at menarche in pre-elite skaters (n = 16; 13.5 +/- 0.9 years) did not differ significantly from the other two groups. By discipline, menarche was, on average, significantly later (P<0.01) in pair skaters (n = 12; 14.5 +/- 1.3 years) than in both free skaters (n = 38; 13.4 +/- 1.0 years) and dancers (n = 17; 13.4 +/- 1.4 years). Early maturing girls (menarche < 12.0 years; n = 2) were not represented in this sample of competitive figure skaters. Mean recalled age at menarche of mothers of skaters (n = 84) was 13.7 +/- 1.3 years and the mother-daughter correlation (n = 56 pairs) was 0.45 (P<0.01). Later maturation was thus characteristic of competitive figure skaters, particularly in elite and more specialized pair skaters, and there was a significant familial resemblance. Verf.-Referat
