Impact of a brief dietary self-monitoring intervention on weight change and CPAP adherence in patients with obstructive sleep apnea.
ABSTRACT OBJECTIVE: Weight 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. METHODS: Forty 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 6weeks. Participants were weighed at baseline, post-treatment (6weeks), and at a 6-week follow up. RESULTS: Recruitment 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 6weeks had greater CPAP adherence at 6 and 12weeks. CONCLUSION: This 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.

ABSTRACT: Abstract Self-monitoring of food intake is a cornerstone of behavioral weight loss interventions, but its use has not been evaluated in the treatment of obese patients with obstructive sleep apnea (OSA). This pilot study described patterns of adherence to dietary self-monitoring in obese patients with OSA and determined associations between self-monitoring and weight loss, psychosocial functioning, and adherence to continuous positive airway pressure treatment. Participants completed a 6-week behavioral weight loss intervention focused on dietary self-monitoring. Approximately one-third of participants were adherent to self-monitoring throughout the course of the intervention and experienced more weight loss than those who did not self-monitor regularly. More frequent dietary self-monitoring also appeared to be associated with adherence to other health behaviors. These preliminary data suggest that use of dietary self-monitoring may be beneficial for promoting weight loss and adherence to other important health behaviors in OSA patients.Behavioral Medicine 11/2013; DOI:10.1080/08964289.2013.842534 · 1.14 Impact Factor
