Children born during the summer are more likely to be diagnosed with attention deficit hyperactivity disorder (ADHD) than children born later in the school year, according to a study conducted by researchers from North Carolina State University and published in the Journal of Health Economics.
"What our research shows is that similar students have significantly different diagnosis rates depending on when their birthday falls in relation to the school year," said lead researcher Melinda Morrill.
The researchers found that children who had been born close to the cut-off date for admission to kindergarten (who would be among the youngest in their classes) were 25 percent more likely to receive an ADHD diagnosis than children born just a few days later (who would start school a year later as the oldest in their classes).
