Kobuch S, Tsang F, Chimoriya R, et al. - Among adults with class 3 obesity, implementation of a multidisciplinary weight management program conferred significant weight loss at 12 months, irrespective of obstructive sleep apnea (OSA) diagnosis or continuous positive air pressure (CPAP) use.

• In adults with class 3 obesity attending a multidisciplinary weight management program, the link between OSA and CPAP usage, and 12-month weight change, were assessed.

• A total of 178 patients joined the program and 111 (62.4 %) completed 12 months in the program; OSA at baseline was present in 63.1 % (n=70), of whom 54.3 % (n=38) were receiving CPAP.

• In all three groups (non-OSA group, OSA with CPAP, and OSA without CPAP), significant weight loss was evident at 12 months.

• The percentage of body weight loss, or the proportion of patients who achieved ≥5 % body weight loss, did not differ statistically significantly across groups.

• Glycosylated hemoglobin in type 2 diabetes mellitus patients decreased significantly from baseline to 12 months (7.8±1.7 % to 7.3±1.4 %), with no difference between groups.
