Contrary to the claims of success made in this March 22nd Press Release no programming implemented by anyone has been demonstrated to have a direct impact on childhood obesity in Anchorage. In fact, as the CDC Report data (such as they are revealed) indicate, during the target window obesity actually increased and any changes were likely random and insignificant.
I suppose the niggling bit is how ASD and the State expects to retain the respect of its students when it is publishing such nonsense. Here we are, telling students they need to be critical thinkers, while we peddle porridge suitable for Little Effie and the Hollow Men.
On the other hand, I was very impressed with the work Trey Coker did with NANA. Granted that it was a corporate attempt to buy “hearts and minds”, but it also dramatically impacted obesity by simply radically increasing activity. In comparison, the policy initiatives engaged in by the State and District had the actual effect of increasing caloric density at the vending machines and eventually reducing the funds available for increasing activity.
I am certainly concerned about childhood obesity, but I would have rather seen a press release that told the truth about where we are, than engage in such shallow attempted manipulation of data to argue success of dubious programs (and that heralded “success” means that we won’t change tactics!) Any high school Stats student could run down why the conclusions in this paper (let alone the press release based upon it) are laughable, and yet they are peddled to the public much like we were sold “Mission Accomplished”.
Yes, the reliance on p values has been decried in the academic literature. Yes, the confidence intervals render the results almost laughable. Yes, the variation makes any trend line likely an artifact. Yes, the text descriptions, looking at percentage change over base, as opposed to percentage no longer obese, is misleading. Yes, BMI is not an accurate gauge of obesity. And yes, there is no evidence that ANY of the strategies applauded was in fact causally related to any change in the weight of any student.
But, how could anyone engage in selling this hooey to students with a straight face? Do we really think our kids don’t know this is make-believe, or are we in such dire straits that in fact, our kids are just as foolish as their parents?
