Since the recorded increase is large and for births within the last 25 years I suspect that changes in diagnosis play a bigger role in the increase than more gradually-changing birth ages and pre-term survival rates (much as I'd like to believe the latter was of huge importance and not just a potentially relevant factor since the relationship between preterm birth and inattention was the subject of my sister's PHd research...) |
