目标:由于地球的引力,月球对地球有显著的影响,其中最明显的表现是潮汐。我们的目的是看看月球的日常周期,像太阳一样,影响分娩的患病率和发生率。
方法:在这项回顾性队列研究中,我们检查了2001年至2019年间乌迪内学术医院的所有分娩情况。包括所有连续的单胎妊娠,自然分娩和阴道分娩。
结果:在此期间,在6939天内分娩了13,349例自发分娩和阴道分娩的单胎妊娠。发现月球在地平线以上的分娩率明显更高(50.63%vs.49.37%,p<0.05)。此外,白天,分娩率明显高于夜间(53.74%vs.45.79%,p<0.05)。结合月球和太阳的高度,大多数交付都是在两者都高于地平线时登记的(27.39%与26.13%,23.25%,或23.24%,p<0.05)。在校正奇偶校验后,这些发现在多变量分析中得到了证实,胎龄,或季节。我们发现出生和月相之间没有相关性。
结论:我们的数据支持月球和太阳在确定出生时间方面的相互作用。需要更多的研究来了解这些现象,并提高我们对分娩机制的理解。
OBJECTIVE: The
Moon has a noticeable influence on the Earth due to its gravity, the most visible manifestation of which are tides. We aimed to see if the
Moon\'s daily cycle, like the Sun\'s, affects the prevalence and incidence of childbirth.
METHODS: In this retrospective cohort study, we examined all deliveries at the Academic Hospital of Udine between 2001 and 2019. All consecutive singleton pregnancies with spontaneous labor and vaginal delivery were included.
RESULTS: During the period, 13,349 singleton pregnancies with spontaneous labor and vaginal delivery were delivered in 6939 days. A significantly higher prevalence of deliveries was found with the
Moon above the horizon (50.63% vs. 49.37%, p < 0.05). Moreover, during the day, there was a significantly higher prevalence of deliveries than during nighttime (53.74% vs. 45.79%, p < 0.05). Combining the
Moon and Sun altitude, the majority of deliveries were registered when both were above the horizon (27.39% vs. 26.13%, 23.25%, or 23.24%, p < 0.05). These findings were confirmed in multivariate analysis after adjusting for parity, gestational age, or season. We found no correlation between birth and the
Moon phase.
CONCLUSIONS: Our data support the interaction of the Moon and the Sun in determining the time of birth. More research is needed to understand these phenomena and improve our understanding of labor initiation mechanisms.
