We aimed to estimate age at menopause using serum antimüllerian hormone (AMH) concentration.
We randomly selected 266 study participants from a pool of 1,265 eligible women in the Tehran Lipid and Glucose Study cohort. We measured AMH levels three times at about 3-year intervals. There were 63 occurrences of menopause in our participants over an average of 6-year follow-up. We built an accelerated failure time model using serum AMH level at the start of follow-up to estimate age at menopause. The goodness of fit for the model was tested using Cox-Snell residuals and the Bland-Altman plot.
We estimated ages at menopause for different levels of serum AMH concentration among women aged 20 to 49 years. For those who reached menopause, serum AMH concentrations about 6 years before the event provided fairly accurate estimates of the age at menopause. The Bland-Altman plot showed an acceptable agreement between predicted and observed values.
Serum AMH concentrations can reasonably forecast the age at menopause for individual women.
我们旨在通过血清抗缪勒管激素(AMH)浓度来估算绝经年龄。
我们从德黑兰血脂和血糖研究队列中随机选择了 266 名符合条件的女性中的 266 名研究参与者。我们在大约 3 年的时间间隔内测量了 AMH 水平三次。在平均 6 年的随访中,我们的参与者中有 63 例发生了绝经。我们使用随访开始时的血清 AMH 水平建立了加速失效时间模型,以估算绝经年龄。通过 Cox-Snell 残差和 Bland-Altman 图测试模型的拟合优度。
我们在 20 至 49 岁的女性中估算了不同血清 AMH 浓度水平的绝经年龄。对于那些达到绝经的人,在事件发生前约 6 年的血清 AMH 浓度提供了绝经年龄的相当准确的估计。Bland-Altman 图显示了预测值和观察值之间可接受的一致性。
血清 AMH 浓度可以合理地预测个体女性的绝经年龄。
