Abstract：
Analysis of data from the representative \"GGP - Contemporary Czech Family Survey\" (2020-2022) on the population of women aged 40-69 years showed that the age of onset of menopause is associated with a low age at the birth of the first child. Women who had their first child before their 20th birthday, a pattern of reproductive behaviour common among generations of women before 1989, have an earlier onset of menopause than older first-time mothers. Conversely, the effect of higher age at first birth (35 years or more) on the delay of menopause has not been proved. However, this issue requires further investigation, as the sample analysed suggests certain tendencies. A larger sample size would be needed to make a conclusive finding.
摘要：
对具有代表性的“GGP-当代捷克家庭调查”（2020-2022）对40-69岁女性人口的数据进行的分析显示，更年期的发病年龄与第一个孩子出生时的低年龄有关。在20岁生日之前生第一个孩子的女人，1989年以前几代妇女中常见的一种生殖行为模式，其更年期比初产妇更早。相反，首次出生时年龄较高（35岁或以上）对绝经延迟的影响尚未得到证实。然而,这个问题需要进一步调查，因为分析的样本表明了某些趋势。需要更大的样本量才能做出结论性发现。
