“…Similarly, Bourey et al demonstrated increased BMI in CPAP users at one month after CPAP initiation, though weight was stable at 6 months. 4 On the other hand, in a well-done randomized, crossover trial of 86 OSA patients, Sharma et al demonstrated decrease in BMI (as well as other markers of metabolic syndrome), with 3 months of active CPAP compared with 3 months of sham CPAP. 5 Most recently, in a study of 40 men with sleep apnea who were randomized to a brief self-management intervention or to usual care, those in the self-management group who were most adherent to CPAP lost the most weight over a 3-month period.…”
