Randomized Study of a Simple Weight Loss Program for Obese Patients With Obstructive Sleep Apnea
15. oktober 2008 opdateret af: Lawson Health Research Institute
A Randomized Controlled Pilot Study of a Simple Weight Loss Program for Obese Patients With Mild to Moderate Obstructive Sleep Apnea
The purpose of the study is to determine if weight loss interventions aimed at lifestyle modification (dietary education, food diary pedometer) result in weight loss in patients with mild-moderate obstructive sleep apnea (OSA) when compared to usual patient care.
The secondary purpose of the study is to determine if the amount of weight loss achieved in a 6 month period results in improvements in snoring and other symptoms and in the frequency of apnea on overnight monitoring.

Detaljeret beskrivelse
The purpose of the study is to determine if weight loss interventions aimed at lifestyle modification (dietary education, food diary pedometer) result in weight loss in patients with mild-moderate obstructive sleep apnea (OSA) when compared to usual patient care. The secondary purpose of the study is to determine if the amount of weight loss achieved in a 6 month period results in improvements in snoring and other symptoms and in the frequency of apnea on overnight monitoring.
Primary Objective
- To determine if weight loss interventions aimed at lifestyle modification (dietary education, food diary pedometer) result in weight loss in patients with mild-moderate OSA when compared to usual care.
- To determine if the amount of weight loss achieved in a 6 month period result in improvements in objective measures of sleep disordered breathing (AHI).
Secondary Objective
- To determine if the weight loss achieved in 6 months result in improvements in OSA symptoms (e.g., snoring, sleepiness) and quality of life.
- To determine if metabolic parameters (e.g., lipids, glucose) improve.
- To determine if there is improvement in sleep structure and oxygenation during sleep.
