芳香疗法吸入对孕妇的身体和心理的影响
It is well known that stress during pregnancy can lead to depression and an increased risk of preterm delivery and low-birth-weight infants. Stress hormones, transmitted through the placenta, can cause neurological effects on both fetuses and neonates. Therefore, it is important to reduce stress where possible in pregnancy women. The aim of this study is to clarify the physical and psychologic effects of inhalation aromatherapy on pregnant women.
众所周知，孕期压力可能导致增加抑郁症、早产儿和低出生体重儿风险。压力激素，通过胎盘传播，可以影响胎儿和新生儿的神经系统。因此，在尽可能的情况下，重要的是减少孕妇的压力。本研究的目的是阐明吸入芳香疗法对孕妇身体和心理的影响。
The study included 13 pregnant women in week 28 of a single pregnancy with a normal course. Participants were randomly assigned into an aromatherapy group (7 participants) and a control group (6 participants). They were seated in the resting, seated position for 10 minutes. During the latter 5 minutes of each 10-minute session, aromatherapy inhalation was performed for the aromatherapy group.
这项研究包括13名孕妇，单胎妊娠，正常过程怀孕28周。参与者被随机分配到一个芳香疗法组（7例）和对照组（6例）。他们坐着休息，坐位持续10分钟。在每一个10分钟的后5分钟，芳香疗法组进行芳香吸入5分钟。
Each participant chose a preferred fragrance from among the essential oils listed below. They are high in linalool and linalyl acetate. These essential oils are safe to use in pregnancy.
1. Lavender (Lavandula angustifolia); linalyl acetate content: 30.68%; linalool content: 31.77%.
2. Petitgrain (Citrus aurantium(Fe)); linalyl acetate content: 50.45%; linalool content: 25.31%.
3. Bergamot (Citrus aurantium L. ssp. Bergamia); linalyl acetate content: 24.76%; linalool content: 9.16%.
每个参与者从下面列出的精油中选择了自己偏爱香味的精油。他们含有高含量的芳樟醇和乙酸芳樟酯。这些精油在怀孕期间使用是安全的。
1. 薰衣草(Lavandula angustifolia)，乙酸芳樟酯含量：30.68%；芳樟醇含量：31.77%。
2. 苦橙(Citrus aurantium(Fe))，乙酸芳樟酯含量：50.45%；芳樟醇含量：25.31%。
3. 佛手柑(Citrus aurantium L. ssp. Bergamia)，乙酸芳樟酯含量：24.76%；芳樟醇含量：9.16%。
Before and after the intervention, the Profile of Mood States (POMS) was measured. During the trial, the heart-rate fluctuations were measured for the autonomic nervous system regulation.
干预前后，测定个人的情绪状态（POMS）。在试验过程中，为自主神经系统调节测量心率波动。
The results of the POMS were such that based on an intragroup comparison, significant differences were observed in the Tension-Anxiety score (p<0.05) and the Anger-Hostility score (p<0.05), and the respective improvements observed were due to aromatherapy. The results of the autonomic nervous system regulation were such that based on an intragroup comparison within the aromatherapy group, the parasympathetic nerve activity increased significantly (p<0.05).
个人情绪状态POMS的测量结果，基于组内比较，紧张焦虑评分（P＜0.05）和愤怒敌意评分（P＜0.05）均有显著的统计学意义，以及因芳香疗法有相应的改进。自主神经系统调节的结果，基于芳香疗法组在组内比较，副交感神经活性显著增加（P＜0.05）。
In conclusion, aromatherapy inhalation using essential oils containing linalyl acetate and linalool was found to be effective for the POMS and parasympathetic nerve activity, based on an intragroup comparison. However, based on a comparison between the groups, no substantial difference was observed; hence, further study is necessary in the future.
总之，使用含有乙酸芳樟酯、芳樟醇的精油进行芳香疗法吸入，对个人情绪状态POMS和副交感神经活性是有效的。然而，基于组间比较，没有观察到实质性的差异，因此，在未来进一步的研究是必要的。
