Excessive stress during pregnancy may cause mental disorders in pregnant women and inhibit fetal growth. Yoga may alleviate stress during pregnancy.
To verify the immediate effects of yoga on stress response during pregnancy.
One group pre-post test was conducted at a hospital in Japan. We recruited 60 healthy primiparas without complications and asked them to attend yoga classes twice a month and to practice yoga at their homes using DVD 3 times a week from 20 gestational weeks until childbirth. Salivary cortisol and alpha-amylase concentration were measured before and after yoga classes at time 1 (27-32 gestational weeks) and time 2 (34-37 gestational weeks). Subjective mood was assessed using the profile of mood states. Saliva values and mood scores before and after each yoga class were compared using paired t-test and Wilcoxon rank-sum test, respectively.
We analyzed 44 and 35 women at time 1 and time 2, respectively. The mean salivary cortisol concentration declined significantly after each yoga class [time 1: 0.36-0.26μg/dL (p<0.001), time 2: 0.32-0.26μg/dL (p=0.001)]. The mean salivary alpha-amylase concentration also decreased significantly following each class [time 1: 72.2-50.8kU/L (p=0.001), time 2: 70.6-52.7kU/L (p=0.006)]. The scores for negative dimensions of mood (Trait-Anxiety, Depression, Anger-Hostility, Fatigue, and Confusion) decreased significantly. The scores of Vigor for a positive dimension of mood significantly increased.
This study indicated the immediate stress reduction effects of yoga during pregnancy.
孕期压力过大可能导致孕妇出现精神障碍，并抑制胎儿生长。瑜伽或许能缓解孕期压力。
验证瑜伽对孕期应激反应的即时效果。
在日本一家医院进行了一组前后测研究。我们招募了60名无并发症的健康初产妇，要求她们从孕20周直至分娩，每月参加两次瑜伽课程，并每周使用DVD在家练习瑜伽3次。在第1阶段（孕27 - 32周）和第2阶段（孕34 - 37周）的瑜伽课程前后，测量唾液皮质醇和α-淀粉酶浓度。使用情绪状态剖面图评估主观情绪。分别采用配对t检验和Wilcoxon秩和检验比较每次瑜伽课程前后的唾液值和情绪得分。
我们分别在第1阶段和第2阶段分析了44名和35名女性的数据。每次瑜伽课程后，唾液皮质醇平均浓度显著下降[第1阶段：0.36 - 0.26μg/dL（p<0.001），第2阶段：0.32 - 0.26μg/dL（p = 0.001）]。每次课程后，唾液α-淀粉酶平均浓度也显著降低[第1阶段：72.2 - 50.8kU/L（p = 0.001），第2阶段：70.6 - 52.7kU/L（p = 0.006）]。情绪负面维度（特质焦虑、抑郁、愤怒 - 敌意、疲劳和困惑）的得分显著降低。情绪积极维度活力的得分显著增加。
本研究表明瑜伽在孕期具有即时减轻压力的效果。
