Abstract

OBJECTIVE: The purpose of this study was to examine whether adults with obesity and metabolic syndrome who screen as high risk for obstructive sleep apnea (OSA) lose less weight as part of a weight loss intervention than those who screen as low risk.

METHOD: We conducted a secondary analysis of a randomized trial comparing 2 weight loss interventions consisting of dietary counseling for adults with obesity and metabolic syndrome. Participants were screened for sleep apnea using a validated screening questionnaire. Percent weight loss was calculated from weight measured at baseline and intervention end (12 months). Weight loss of 5% or greater was considered clinically significant. Multivariate linear and logistic regression models estimated the association between OSA screening status (high vs. low risk) and percent weight loss and clinically significant weight loss, adjusting for relevant covariates including body mass index and sleep duration.

RESULTS: Nearly half of participants (45.8%) screened as high risk for OSA. Participants who screened as high risk for OSA lost less weight (1.2% +/- 4.2% vs. 4.2% +/- 5.3%) and were less likely to lose 5% or greater (24.4% vs. 75.6%) than participants without OSA.

CONCLUSION: Among adults with obesity and metabolic syndrome, those at high risk for OSA lost less weight in response to a dietary counseling intervention than adults with low risk of OSA. Routine OSA screening should be considered as part of weight loss treatment programs. Additional research is needed to determine how to tailor weight loss treatment for those with high risk for OSA.
