Abstract

CONTEXT

Anti-Müllerian hormone (AMH) levels are used worldwide as a screening tool for the duration of the female reproductive lifespan. Although AMH levels are associated with age at menopause, individual predictions of menopause with a single AMH measurement are unreliable.

OBJECTIVE

This study investigated whether individual AMH decline patterns can improve the prediction of menopause compared with a single measurement.

DESIGN

The study population comprised 2434 premenopausal women from the population-based Doetinchem Cohort Study. Participants were followed up every 5 years for a total of 20 years, and AMH was measured in 6699 plasma samples with the picoAMH assay. Longitudinal statistical modeling was combined with time varying Cox modeling, to integrate multiple AMH measurements per woman.

RESULTS

The mean age at menopause was 50 years, and 7.4% of the women who reached menopause during follow-up did so before age 45 years. For a 25-year-old, the AMH decline rate between ages 20 and 25 years increased the C-statistic of menopause prediction from 0.64 to 0.69. Beyond that age, the AMH decline rate did not improve predictions of menopause or early menopause. For women younger than age 30 years, for whom menopause prediction is arguably most relevant, the models underestimated the risk of early menopause.

CONCLUSION

These results suggest that knowledge of the AMH decline rate does not improve the prediction of menopause. Based on the low discriminative ability and underestimation of the risk of early menopause, the use of AMH as a screening method for the timing of menopause cannot currently be advocated.

摘要

背景

抗苗勒管激素(AMH)水平被全球用作女性生殖寿命的筛查工具。尽管 AMH 水平与绝经年龄相关,但仅凭单次 AMH 测量来预测绝经是不可靠的。

目的

本研究旨在探讨个体 AMH 下降模式是否比单次测量能更好地预测绝经。

设计

该研究的研究人群包括来自基于人群的多塞特钦彻姆队列研究的 2434 名绝经前女性。参与者每 5 年随访一次,共 20 年,采用 picoAMH 检测法对 6699 份血浆样本进行 AMH 测量。将纵向统计建模与时间变化的 Cox 建模相结合,以整合每位女性的多次 AMH 测量。

结果

绝经的平均年龄为 50 岁,在随访期间达到绝经的女性中有 7.4%在 45 岁之前绝经。对于 25 岁的女性,20 岁至 25 岁之间 AMH 下降率将绝经预测的 C 统计量从 0.64 提高到 0.69。超过这个年龄,AMH 下降率并不能改善绝经或早绝经的预测。对于年龄小于 30 岁的女性,早绝经的预测更具相关性,这些模型低估了早绝经的风险。

结论

这些结果表明,了解 AMH 下降率并不能改善绝经的预测。基于低的区分能力和低估早绝经的风险,目前不能提倡使用 AMH 作为绝经时间的筛查方法。
