Models for Evaluate the Proximity of the Moon on the Frequency of Births

Two Models for Evaluate the Effect of the Proximity of the Moon on the Frequency of Births. Study on Mexican Population

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

Study Overview

• Status: Completed
• Conditions: Establish the Relationship Between Moon and Births
• Intervention / Treatment: Behavioral: pregnancy

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

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
First model of analysis (Classic model)	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	up to 12 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Second model of analysis. Luminosity - Births	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.	up to 34 weeks
