The purpose of this study was to elucidate the mean age at menarche in Icelandic girls and compare it with results from other Scandinavian populations as well as in other ethnic groups. The study was performed during the school year 1972-1973 on a cross-sectional sample of 682 girls (aged 8.5 to over 17 years), constituting 9.5% of the girls from the third to eleventh forms in all the primary and secondary schools of Reykjavik. The mean age at menarche in Iceland, elicited by the status quo method, proved to be 13.06 +/- 0.10 years (S.D. 1.17 years). According to the information given by the girls (recall method), the earliest time of menstruation was 9.83 years and the latest 15.17 years, at which age all but one of the girls were menstruating.
本研究的目的是阐明冰岛女孩月经初潮的平均年龄，并将其与其他斯堪的纳维亚人群以及其他种族群体的结果进行比较。该研究于1972 - 1973学年进行，以682名女孩（年龄在8.5岁至17岁以上）为横断面样本，占雷克雅未克所有中小学三年级至十一年级女生的9.5%。通过现状法得出，冰岛女孩月经初潮的平均年龄为13.06±0.10岁（标准差1.17岁）。根据女孩提供的信息（回忆法），最早月经时间为9.83岁，最晚为15.17岁，在这个年龄除一名女孩外所有女孩都已月经初潮。
