“ Obesity and OSA often coexist: >40% of obese pts have significant OSA 70% of OSA pts are obese ” “ A 10% increase in weight gain is associated with a 6-fold increase in the odds of developing OSA. … every 6 kg/m2 increment in BMI increases OSA risk, more than 4-fold. ” Lancet 2002 Sleep Heart Health Study.

“…OSA in obese patients may place them at higher risk for cardiovascular outcomes than obese patients without OSA, though such assertions await firm clinical evidence. ” CHEST 2000;118:580-586 “ Obese OSA patients can potentially be at higher risk for cardiovascular morbidity and mortality… …this will need to be addressed in future prospective studies. ” “…unfortunately most studies in obese patients did not assess for OSA and exclude it as a possible confounder. ” Kannan Ramar, Sean Caples.
