摘要

食指和无名指的比例(2D:4D)是反映产前激素暴露的潜在生物标志物,因此对生殖健康具有长期影响。本研究旨在确定2D:4D(代表产前激素环境,即早期雄激素暴露)与印度锡金妇女月经初潮提前或延迟的关系。采用分层随机抽样的方法,研究了来自印度锡金Soreng地区的119名年龄在18-49岁的夏尔巴人部落妇女。为了计算2D:4D比值,使用标准程序测量食指和无名指(2D和4D)的长度。分类平均比较显示,与2D:4D比例更男性化的女性相比,2D:4D比例更女性化的女性(左手和右手)月经初潮的年龄(以年计)明显更早。线性回归分析显示,左侧2D:4D与月经初潮年龄显著相关。2D:4D与月经初潮年龄之间存在关联,表明妇女的生殖模式与产前荷尔蒙环境的影响之间存在联系,这是提前或推迟月经初潮年龄的一个重要因素。

Low 2D:4D is associated with delayed age at menarche among women of Sikkim, India
The index-finger and ring-finger ratio (2D:4D) is a potential biomarker that reflects prenatal hormonal exposure and thus has a long-term impact on reproductive health. The present study aims to determine the relationship between the 2D:4D (representing the prenatal hormonal environment, i.e., early androgen exposure) and early or delayed age at menarche among women in Sikkim, India. A total of one hundred nineteen Sherpa tribal women, ages 18–49, from the Soreng district of Sikkim, India, were included in the study using a stratified random sampling method. To calculate the 2D:4D ratio, the lengths of the index and ring fingers (2D and 4D) were measured using standard procedures. The category-wise mean comparison revealed that women with a more feminine 2D:4D ratio (in both left and right hand) had significantly earlier age at menarche (in years) compared to women with a more masculine 2D:4D ratio. The linear regression analysis revealed that the left 2D:4D was significantly related to menarche age. There is an association between the 2D:4D and menarche age, indicating a link between women’s reproduction patterns and the influence of the prenatal hormonal environment as an important factor in attaining an early or delayed menarcheal age.
