Brief summary

The purpose of this study is to establish the relationship between moon and births through two analytic models.

Detailed description

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

Design outcomes

Primary

Measure	Time frame	Description
First model of analysis (Classic model)	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

Measure	Time frame	Description
Second model of analysis. Luminosity - Births	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.
