About this study

Retrospective, descriptive and observational study. Classical model performs comparisons of births among lunar periods, lineal, cubical and exponential estimation was performed in the SPSS software and the inflection point of the curve was estimated using the formula x=[In (1/ebx)]/ebx in the Geogebra model. The significance was establish by a p value of ≤ 0.05 (95% IC).

The second analysis was performed by the difference of media between all the stages of the moon cycle as in another trials. The difference was establish by the T-student test. The difference between groups was performed by the one way ANOVA test.

This study had the review and approval from the Ethics Committee of the institution and according with Mexican regulation, and in adherence to the Helsinki declaration and International Conference for Harmonisation

Behavioral

Observational study in order to establish relationship between moon and births

Other names: Statistics analysis

Primary outcomes

  1. First model of analysis (Classic model)

    Time frame: up to 12 months

    Initial association was tempted to be done based on previous analysis described.

    The "Gibada moon" phase showed a significant difference versus Full moon and new moon, due to average birth is increased in this phase

Secondary outcomes

  1. Second model of analysis. Luminosity - Births

    Time frame: up to 34 weeks

    For this analysis, the moon luminosity was estimated as percentage (%), as a measure of proximity between moon and the earth, and was correlated to number of births. More the percentage of light is, closest to the earth the moon is.
