The study at the Columbia University Medical Center (CUMC) had a look at medical records of 1.75 million patients, treated at NewYork-Presbyterian Hospital/CUMC between 1985 and 2013. The study compared 1,688 diseases against the birth dates and findings were published in the Journal of American Medical Informatics Association.
Summer babies are generally healthier and this is believed to be because of peaked vitamin D exposure. Those born in June, July and August had higher birth weights, and most grew up to be tall adults. Those born in December, January and February weighed less at birth and reached puberty earlier, they were also shorter adults.
Children born in fall/autumn are more susceptible to asthma, this is linked to the fact that these children are still very young when experiencing their first winter cold and flu season. This 2008 study claims that those born in September, October and November had 30% more chance of being asthmatic.
More than 6 million deaths related to heart disease were looked at in this 2011 study which showed that that most of these individuals were November born.
Those born in early spring are more likely to develop cardiovascular diseases while those born in early fall are more likely to suffer from respiratory illness.
