Dear Colleagues,
All over the news today is a claim that, by implication, watching TV in
infancy basically causes attention problems in children. Of course, the AAP
doesn't say this, but that doesn't matter since the press is splattering ITS
understanding of the claim all over the place, and this is the message
people will take home with them.
In reading over the article to find the source of the claim (found at
http://www.aap.org/advocacy/releases/apr04studies.htm) and the strength of
the relationship, I found that the authors use a logistic regression
statistic that I don't understand.
Having never used logistic regression before, I'm not familiar with the
concept of an "odds ratio," at least not in the sense that it's used here.
On p. 712, it is shown that the odds ratio (of WHAT I cannot tell) is 1.09.
Apparently, this statistic shows the strength of the relation between
tv-watching in infancy and later attention problems. Can anyone explain
this statistic to me?
In their position expressed today, the American Academy of Pediatrics
may be even more guilty of scientific misconduct than their previous claim
that watching TV before age 2 is bad and should be avoided.
