Most American babies are born around August and September:

Which happens to be the cut off date for Kindergarten in many states.

Since most children are born in Aug/September, you'd probably have the most premature births around then too right?
Premature children are 70% more likely to have ADHD:

Could it be that a lot of premature children happen to come right before the early/mid September deadline at the peak of the "birthing season"?
If the relationship between ADHD and prematurity is correct, these children would face a double whammy...being young for their grade and ADHD.
- antics 16y agoThat's very insightful, but it's my guess is that it's not as salient as one would think. Scientists (at least in the lab) will typically use a number of metrics to measure ADHD, most notably cerebral myelination. ADHD tends to involve improper development in this regard (i.e., the brain does NOT myelinate as fast as one would expect). Since the authors posit that younger children may simply be less mature, my suspicion is that they are talking about this. And the obvious thing to do would be to correct for what you talk about (in fact, it's hard to see how they could get into a journal and not do so).
