In the present study we have shown that preDM and
T2DM are commonly observed and associated with
OSA in extremely obese subjects. Our findings support
the recommendations from the International Diabetes
Federation (IDF) suggesting that subjects with T2DM
should be screened for OSA [7]. If the relationship
between preDM and OSA is verified by others, this may
indicate that obese subjects with preDM should also be
screened for OSA.
