This study was undertaken to use the Arizona State birth certificate database for Phoenix metropolitan hospitals, in conjunction with National Weather Service records to determine whether there is a relationship between birth rate and meteorologic or lunar conditions. This study attempts to dispel or lend significance to beliefs among hospital staff that the phase of the moon and/or meteorologic conditions are related to birth rate.
Birth records were limited to spontaneous vaginal deliveries, 37 to 40 weeks' gestation, in Phoenix, between 1995 and 2000 (n = 167,956). Daily birth counts were merged with daily surface weather statistics from the National Weather Service for Sky Harbor Airport, and records of lunar phase for the same period.
The analyses revealed no significant correlates of birth rate.
Although there exists a popular belief that the phase of the lunar cycle and weather conditions affect birth rate, no such evidence was found in this study.
本研究旨在利用亚利桑那州凤凰城大都市医院的出生证明数据库,并结合国家气象局记录,以确定出生率与气象或月球条件之间是否存在关联。本研究试图消除或证实医院工作人员中关于月相和/或气象条件与出生率相关的看法。
出生记录仅限于1995年至2000年期间在凤凰城发生的、孕周为37至40周的自然阴道分娩(n = 167,956)。每日出生人数与国家气象局提供的天港机场每日地面天气统计数据以及同期月相记录进行合并。
分析显示出生率无显著相关性。
尽管普遍认为月相周期和天气条件会影响出生率,但本研究未发现此类证据。
