(1) Background: Basic vital signs change during normal pregnancy as they reflect the adaptation of maternal physiology. Electronic wearables like fitness bracelets have the potential to provide vital signs continuously in the home environment of pregnant women. (2) Methods: We performed a prospective observational study from November 2019 to November 2020 including healthy pregnant women, who recorded their wrist skin temperature, heart rate, heart rate variability, and breathing rate using an electronic wearable. In addition, eight emotions were assessed weekly using five-point Likert scales. Descriptive statistics and a multivariate model were applied to correlate the physiological parameters with maternal emotions. (3) Results: We analyzed data from 23 women using the electronic wearable during pregnancy. We calculated standard curves for each physiological parameter, which partially differed from the literature. We showed a significant association of several emotions like feeling stressed, tired, or happy with the course of physiological parameters. (4) Conclusions: Our data indicate that electronic wearables are helpful for closely observing vital signs in pregnancy and to establish modern curves for the physiological course of these parameters. In addition to physiological adaptation mechanisms and pregnancy disorders, emotions have the potential to influence the course of physiological parameters in pregnancy.
(1) 背景：基本生命体征在正常妊娠期间会发生变化，因为它们反映了母体生理学的适应性。电子可穿戴设备，如健身手环，有可能在孕妇的家庭环境中连续提供生命体征数据。
(2) 方法：我们进行了一项前瞻性观察研究，纳入了 2019 年 11 月至 2020 年 11 月期间的健康孕妇，她们使用电子可穿戴设备记录腕部皮肤温度、心率、心率变异性和呼吸频率。此外，每周还使用五点 Likert 量表评估 8 种情绪。应用描述性统计和多变量模型将生理参数与产妇情绪相关联。
(3) 结果：我们分析了 23 名女性在怀孕期间使用电子可穿戴设备的数据。我们为每个生理参数计算了标准曲线，这些曲线与文献中的部分结果有所不同。我们发现，一些情绪，如感到压力大、疲倦或高兴，与生理参数的变化有显著关联。
(4) 结论：我们的数据表明，电子可穿戴设备有助于密切观察妊娠期间的生命体征，并建立这些参数的生理变化的现代曲线。除了生理适应机制和妊娠障碍外，情绪有可能影响妊娠期间生理参数的变化。
