I took my physical a few months ago and I am not sure if they were focusing on the bmi part or not . I am certainly not obese but "knew" I was 15 pounds over my ideal weight(or so I thought) . They did weigh me but asked me my height(which would be have been a good place to add 2 inches if I were worried about this) and I gave them my true height. Nothing more was said about this as I was aware that this bmi thing could potentially be used as a determination for a sleep study.
Anyway, while waiting around for the results of a diabetes test, I was looking at a weight/height bmi chart on the wall. I was surprised by the results that stated I was overweight and dancing close to being pushed into the obese range. The only way to get into the normal range was to be at a weight I hadn't been at since junior year in high school (and I was rail thin then).
I know what my ideal weight is and that is considered overweight.
Anyway, I went through the rest of the exam and nothing was said about sleep studies nor did I ask. 2 months later , I see the heavier guys in the feeder department huddling around with looks of seriousness on their faces that indicate to me that the local dunkin donuts might be closing. I leaned in closer to hear them discussing going back to the doctor in three months, sleep studies etc. This is combination with a narrowing of the list of doctors qualified to conduct the dot exams. Looks like to me , as the original poster said, is that the sleep apnea /bmi part of the dot exam is now in full effect.
For those on the edge of qualifying for this test, pull back from the edge if you can. For those who are definitely obese by any measure, it's a harder road to avoid being hooked up to the c pap machine . If you still got a year and 1/2 before your first encounter with the new dot exam, see if you can do anything about it.
