概括
母亲的智能戒指数据,包括睡眠和活动,与妊娠年龄相关. 这些生理数据可以以71%的准确度预测与预计分娩日 (EDD) 相对的怀孕时间.
科学领域:
- 生殖内分泌学 生殖内分泌学
- 生理监测 生理监测
- 孕产妇和胎儿医学 孕产妇和胎儿医学
背景情况:
- 分娩是一个复杂的生理过程,涉及母亲,胎儿和胎盘组织.
- 母亲生理学指标可能反映出从怀孕到分娩的过渡.
- 了解怀孕持续时间和预测分娩开始对于母婴护理至关重要.
研究的目的:
- 调查通过智能戒指收集的母亲生理指标与妊娠年龄之间的关联.
- 确定生理学数据是否可以预测分娩是否在预计分娩日 (EDD) 之前或之后开始.
- 探索自我报告的分娩症状与妊娠年龄或分娩时间之间的关系.
主要方法:
- 招募了118名怀孕的参与者在他们的第三个三个月.
- 利用连续佩戴的智能戒指设备来监测心率,心率变化,皮肤温度,睡眠和身体活动.
- 收集了关于分娩症状,疼痛,疲劳和情绪的每周调查数据.
- 使用混合效应回归来分析指标与妊娠年龄/分娩时间之间的关联.
- 训练了一种增强的随机森林模型,以预测与EDD相对的分娩开始.
主要成果:
- 许多睡眠,活动,疼痛,疲劳和分娩症状指标与妊娠年龄相关.
- 妊娠年龄的提升与静止心率降低和心率变化增加有关.
- 随着妊娠年龄的增长,身体活动和睡眠时间的减少.
- 随机森林模型预测了通过EDD的怀孕,接收器操作曲线 (AUC) 下的面积为0.71.
- 自我报告的分娩症状与妊娠年龄相关,但与EDD相对的分娩时间无关.
结论:
- 在孕期第三季度使用智能戒指的母亲生理数据显示与妊娠年龄的相关性.
- 智能戒指数据显示,有可能改善与EDD相对的怀孕持续时间的预测.
- 自我报告的症状对分娩时间的预测能力不如客观的生理指标.

Prediction Intervals
The interval estimate of any variable is known as the prediction interval. It helps decide if a point estimate is dependable.
However, the point estimate is most likely not the exact value of the population parameter, but close to it. After calculating point estimates, we construct interval estimates, called confidence intervals or prediction intervals. This prediction interval comprises a range of values unlike the point estimate and is a better predictor of the observed sample value, y.

Secretory Phase
The secretory phase of the menstrual cycle, spanning from day 14 to 28 in a typical 28-day cycle, is a period of significant physiological changes in the female reproductive system. This phase commences immediately after ovulation and is characterized by the preparation of the endometrium for potential embryo implantation.
Following ovulation, the corpus luteum, a temporary endocrine structure, produces progesterone and estrogens. These hormones stimulate the growth and coiling of endometrial...
