closeAre the regressions population weighted?
Posted by jaylusk22 on 07 Mar 2013 at 04:33 GMT
I am curious to know if the regressions are population weighted as indicated in the text? When I download portions of the data (admittedly not the exact same as the authors are using), I get significant differences in the weighted and unweighted models with the unweighted results being more similar to those reported in the text. I report the differences here:

I believe that I answered my own question. The above comment was in reference to regressions run using "national prevalence" as the dependent variable. When I switch and use "IGT comparative prevalence", which is apparently some sort of age-adjusted measure, then i find more similar results to that reported in the paper when the weights are applied. Interestingly, the sugar result is not significant in the unweighted model.
