People born in the autumn live longer than those born in the spring and are less likely to fall chronically ill when they are older, an Austrian scientist said Thursday.
Using census data for more than 1 million people in Austria, Denmark and Australia, scientists at the Max Planck Institute for Demographic Research in the northern German town of Rostock found the month of birth was related to life expectancy over the age of 50.
Seasonal differences in what mothers ate during pregnancy, and infections occurring at different times of the year could both have an impact on the health of a new-born baby and could influence its life expectancy in older age.
“A mother giving birth in spring spends the last phase of her pregnancy in winter, when she will eat less vitamins than in summer,” said Gabriele Doblhammer, one of a team of scientists who carried out the research.
“When she stops breast-feeding and starts giving her baby normal food, it’s in the hot weeks of summer when babies are prone to infections of the digestive system.”
Babies born in the autumn weighed more than those born at springtime, she said. In later life, low birth weight was associated with increased blood pressure, cholesterol levels, some forms of obesity and a decrease in lung function.
