SALT LAKE CITY – A new study suggests that in states where children must turn 5 years old by Sept. 1 in order to start kindergarten that year, children born in August are more likely to receive an ADHD diagnosis.

What’s going on: Researchers in the new study found that there were more diagnoses among children born in August, specifikt i stater hvor der er en Sept. 1 cutoff date to start kindergartens, CNN reports.

  • These August-born children would then be the youngest in their classes, the study notes.
  • “We saw nothing for any of the months apart from August to September , where we saw this big difference, “said Timothy Layton, an assistant professor of health care policy at Harvard Medical School, who was the lead author on the study. “We saw that this was only in states that had a Sept. 1 cutoff.” There was nothing in states that did not have that. “

Why it matters: ” Our findings suggest the possibility that large numbers of kids are being overdiagnosed and overtreated for ADHD because they happen to be relatively immature compared to their older classmates in the early years of elementary school, “Layton said, according to Science Daily.

Method: The study looked at more than 407,000 US children born from 2007 to 2009. Researchers tracked the diagnoses through an insurance database.
