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 Outcome Measures:
- Post treatment apnea-hypopnea index (AHI)
- Post treatment weight (kg)
Secondary Outcome Measures:
- Change in snoring (Visual analogue scale)
- Quality of life
- Excessive daytime sleepiness
- Body mass index (BMI)
- Waist-hip ratio (WHR)
- Blood pressure
- Neck size
- Lipid and glucose levels
- Sleep fragmentation
- Oxygen saturation
