摘要

研究目的：评估亚洲人初潮年龄的变化：研究设计：回顾性队列研究：研究设计：回顾性队列研究：我们纳入了来自亚洲 6 个国家的 548830 名女性。数据来自参与亚洲队列联盟（ACC）的 20 个队列和另外两个队列研究：日本多机构协作队列研究（J-MICC）和日本护士健康研究（JNHS）的初潮年龄数据。研究采用连接点回归法来评估不同出生年份和不同国家的初潮年龄变化：研究包括来自六个亚洲国家（中国、伊朗、日本、韩国、马来西亚和新加坡）的队列数据。出生年份从 1873 年到 1995 年不等。月经初潮的平均年龄为 14.0 岁，标准差（SD）为 1.4 岁，介于 12.6 岁至 15.5 岁之间。在所有 6 个国家中，超过 100 岁的初潮年龄总体上有所下降。中国从 1926 年到 1960 年呈现出下降、上升和随后下降的混合模式。伊朗和马来西亚的初潮年龄在 1985 年至 1990 年间急剧下降，APC 值分别为-4.48 和-1.24，而日本、韩国和新加坡自 20 世纪 80 年代以来几乎呈线性下降，尤其是新加坡在 1993 年至 1995 年间的 APC 值为-3.41：总的来说，我们观察到初潮年龄在下降，而变化的速度因国家而异。需要进行更多的长期观察，以研究造成亚洲各国趋势差异的因素。这项研究可作为加强全球健康运动的工具。

Age at menarche by birth cohort: A pooled analysis of half a million women in Asia

Objectives

To evaluate changes in the age at menarche in Asian populations.

Study design

Retrospective cohort study.

Methods

We included 548,830 women from six countries in Asia. The data were sourced from 20 cohorts participating in the Asia Cohort Consortium (ACC) and two additional cohort studies: Japan Multi-institutional Collaborative Cohorts (J-MICC), and Japan Nurse Health Study (JNHS) with data on age at menarche. Joinpoint regression was used to evaluate changes in age at menarche by birth year and by country.

Results

The study includes data from cohorts in six Asian countries namely, China, Iran, Japan, Korea, Malaysia and Singapore. Birth cohorts ranged from 1873 to 1995. The mean age of menarche was 14.0 years with a standard deviation (SD) of 1.4 years, ranged from 12.6 to 15.5 years. Over 100 years age at menarche showed an overall decrease in all six countries. China showed a mixed pattern of decrease, increase, and subsequent decrease from 1926 to 1960. Iran and Malaysia experienced a sharp decline between about 1985 and 1990, with APC values of −4.48 and −1.24, respectively, while Japan, South Korea, and Singapore exhibited a nearly linear decline since the 1980s, notably with an APC of −3.41 in Singapore from 1993 to 1995.

Conclusions

Overall, we observed a declining age at menarche, while the pace of the change differed by country. Additional long-term observation is needed to examine the contributing factors of differences in trend across Asian countries. The study could serve as a tool to strengthen global health campaigns.
