Some researchers believe that the month in which we are born is related to trends that mark our health and our way of relating to the environment. This type of theory emphasizes the importance of the stimuli that are received during the months of gestation and the first days after birth, and this sequence of stimuli could be different depending on the period of the year they cover.

In line with this type of hypothesis, a group of researchers from Columbia University set out to investigate whether there is a correlation between the month of birth and the risk of having a list of diseases. Their conclusions seem to correspond to what they wanted to demonstrate and have recently been published in the Journal of the American Medical Informatics Association.

Statistic Things

This team of researchers used the existing information in databases as raw material and looked for correlations between the moment of birth and the propensity to each disease through the application of an algorithm.

The analysis of statistical data served to verify 1,688 diseases presented by the sample (1,749,400 people born between 1985 and 2013 registered in New York databases), 55 were related to the month of birth of the group of individuals. In addition, of those 55 correlations between the time of birth and risk of illness, 19 have already been found in previous studies, and 20 were related to those 19.

Months And Diseases

The correlations of disease risk are, for each month of birth, the following:

  1. January: cardiomyopathy and hypertension.
  2. February: lung or bronchial cancer.
  3. March: arrhythmias, heart failure, and mitral valve disorder.
  4. April: angina.
  5. May: there was no greater risk of suffering from any disease due to the fact of being born in this month.
  6. June: pre-infarction syndrome.
  7. July: asthma.
  8. August: As the group of those born in May, there was no special risk of suffering from any disease.
  9. September: vomiting.
  10. October: sexually transmitted diseases, chest infections, and insect bites.
  11. November: arrhythmia, mitral valve disorder, and lung cancer.
  12. December: only bruises.

Do Not Let The Alarms Go Off!

It is appropriate to assume these data in a critical sense. As it has already been said a thousand times, the correlation does not mean causality, and there is nothing to indicate that the fact of being born in one month or another means that we will all have some of these diseases in a latent state.

This study simply uses the month of birth as a criterion to predict the frequency with which certain diseases occur in the group born at each time of the year. However, it is not a case study: it focuses on a collective phenomenon that can only be interpreted as a tendency and only appear in very large groups of people.
