Scientists from Columbia University have developed a computational method to study the relationship between the month of birth and the risk of certain diseases. The researchers used data on 1,7 million patients from New York medical facilities—and as it turned out, 55 diseases correspond to the month of birth.
Overall, the study showed that those born in May are less at risk of diseases, and those born in October are the most vulnerable, says "MegaUniverse".
Previous research has found a link between the month of birth and certain diseases, for example asthma, attention deficit hyperactivity disorder. This led the Columbia University specialists to compare 1688 with the birth dates and medical histories of patients who sought medical attention between 1985 and 2013.
The study ruled out more than 1600 correlations and confirmed 39 relationships previously known in the medical literature, and also discovered 16 new relationships (including 9 heart diseases, which are the leading cause of death in many countries around the world today). The researchers performed statistical tests to verify that the association of these 55 diseases with the horoscope was not random.
"We don't urge patients to get too excited about these results: although we found an association, month of birth is a relatively minor change compared to a number of other influencing factors, such as diet and physical activity", assures the lead author of the study Nicholas Tatonetti (Nicholas Tatonetti), associate professor of biomedical informatics at Columbia University Medical Center.
The authors of the study found, for example, that onPeople born in July and October are most prone to asthma claims. The results of the previous survey, conducted in Denmark, pointed to May and August. The difference is explained by the fact that at that time the level of solar activity in Denmark is similar to that in July and October in New York.
As for dattention efficiency and hyperactivity, children born in November suffer from it more often in New York. This conclusion coincides with the results of the Swedish study, which also points to November.
People born in March, are at risk for atrial fibrillation, heart failure and mitral valve disorders. One in 40 cases of atrial fibrillation is due to seasonal effects of month of birth.
Previous research using the Australian and Danish databases showed that people born between March and June were more likely to have heart disease than others and also that their life expectancy is shorter.
"These data can help scientists look at disease risk factors in a new way Tatonetti says. - In the future, we plan to repeat our research based on the database from other regions of the US and the world to understand how the results can vary with the change of season and environmental factors.” The scientific article with the results of the analysis was published in the Journal of American Medical Informatics Association.
