哺乳期的母亲在牛奶下降期间经历皮质醇水平的变化,无论是哺乳还是抽奶. 这种荷尔蒙转变发生在婴儿存在的独立,通过母乳传递母亲皮质醇水平的信号.
科学领域:
- 内分泌学 在内分泌学.
- 人体生理学 人体生理学
- 哺乳期生物学 哺乳期生物学
背景情况:
- 皮质醇是一种关键的葡萄糖皮质激素,调节压力,能量和免疫功能.
- 在动物模型中,哺乳期与改变的葡萄皮质皮质体信号传递有关.
- 人类有限的数据表明,在人类哺乳期间,葡萄糖皮质体信号传递可能发生变化.
研究的目的:
- 为了调查母乳养母亲的乳液放出/分泌是否会改变皮质醇水平.
- 为了确定这些皮质醇变化是否需要婴儿的存在.
- 探索母亲皮质醇与母乳中的皮质醇之间的关系.
主要方法:
- 母乳唾液皮质醇测量是在哺乳前和哺乳后,机械牛奶表达或控制活动.
- 唾液样本是在会议前和会议后30分钟收集的.
- 母亲提供了抽奶样本用于皮质醇分析.
主要成果:
- 哺乳和机械乳都导致母亲皮质醇的显著下降.
- 这些皮质醇降低是独立于婴儿的存在.
- 孕产妇产前皮质醇与抽奶中的皮质醇水平呈正相关性.
- 较高的孕产妇压力与较高的前期皮质醇和乳汁释放后更大的皮质醇下降相关.
结论:
- 乳汁释放,与或没有婴儿,调节母亲的皮质醇水平.
- 母乳可以向后代传递母亲的皮质醇状况.
- 这些发现突出了通过母乳传递母亲激素信号的途径.
