以前关于月经初潮时自我报告年龄的重复性的研究一直受到限制，因为研究样本少，随访时间短，而且包括的女性年龄跨度有限。本研究评估了6731名年龄差异较大的女性在提供月经初潮年龄信息时月经初潮年龄的重复性。这些女性在1986-1987年和1994-1995年的自我调查问卷中报告了月经初潮的年龄。他们都是挪威特罗莫斯的居民，1994-1995年年龄在25-73岁之间。为了调查两个时间点自我报告的月经初潮年龄之间的一致性，采用皮尔逊相关系数来评估两次报告的月经初潮年龄之间的线性相关性。分析是按年龄分层的。制作了Bland-Altman地块，并计算了协议的界限。我们发现1986-1987年间自我报告的月经初潮年龄与1994-1995年间的月经初潮年龄有很高的相关性和很强的一致性。总体皮尔逊相关系数为0.84，不随女性年龄增长而减弱。Bland-Altman的情节显示，在自我报告的月经初潮年龄方面，这一点非常一致。自我报告的月经初潮年龄之间的平均差异为0.01岁，符合范围−为1.52到1.54。我们发现，月经初潮时自我报告的年龄具有很高的重复性。两项调查的平均月经初潮年龄相同(13.2岁)，95%的女性报告初潮年龄相同或相差1岁。在1986-1987年和1994-1995年间，只有0.7%的女性报告了初潮年龄，年龄相差超过2岁。
Previous studies of the reproducibility of self-reported age at menarche have been limited because of small study samples, short follow-up and the limited age span of the women included. The present study assessed the reproducibility of age at menarche in 6731 women with a wide variation of age when giving the information about age at menarche. The women reported age at menarche in a self-administered questionnaire, both in 1986–1987 and 1994–1995. They were all residents of Tromsø, Norway, and aged 25–73 in 1994–1995. In order to investigate the agreement between self-reported age at menarche at the two points in time, Pearson’s correlation coefficient was applied to assess the linear correlation between the reported menarcheal age at the two occasions. Analyses were stratified for age. A Bland-Altman plot was produced and limits of agreement computed. We found a high correlation and a strong agreement between self-reported age at menarche in 1986–1987 and 1994–1995. The overall Pearson’s correlation coefficient was 0.84 and was not attenuated by increasing age of the women. The Bland-Altman plot showed a strong agreement in self-reported age at menarche. The mean difference between self-reported age at menarche was 0.01 years with limits of agreement −1.52 to 1.54. We found high reproducibility of self-reported age at menarche. The mean menarcheal age in the two surveys was identical (13.2 years) with 95% of the women reporting the same age at menarche or with a difference of 1 year. Only 0.7% of the women reported age at menarche with a difference of more than 2 years in 1986–1987 and 1994–1995.
