ObjectiveWeight loss can decrease the severity of obstructive sleep apnea (OSA) in many obese individuals; however, very few studies have investigated the effects of behavioral weight loss interventions for patients with OSA. The aims of this pilot study were to determine the feasibility and initial effects on weight and continuous positive airway pressure (CPAP) use of a brief minimal-contact self-monitoring-based weight loss intervention (SM). An additional aim was to investigate the association between weight loss and CPAP adherence.MethodsForty obese men and women diagnosed with mild or moderate OSA were randomized to either the SM or an attention-control (AC) condition. SM participants completed daily dietary logs for 6 weeks. Participants were weighed at baseline, post-treatment (6 weeks), and at a 6-week follow up.ResultsRecruitment and retention were good in this study and attrition rates did not differ significantly by group. Intent to treat repeated measures ANOVA indicated a main effect of time (but not group), such that both groups lost weight over time. Pearson r correlations between weight change and CPAP adherence indicated that among SM participants, 6-week weight loss was correlated with CPAP adherence at post-treatment and follow-up, such that SM participants with greater weight loss at 6 weeks had greater CPAP adherence at 6 and 12 weeks.ConclusionThis study provides initial support for the beneficial effects of a minimal-contact weight loss intervention for patients with obstructive sleep apnea and highlights a possible association between weight loss and CPAP adherence.Copyright © 2012 Elsevier Inc.
