Lifestyle modification program
Simple lifestyle advice
At the 1st session, the dietitian carried out a complete behavioral assessment, with emphasis on patient's current eating and lifestyle patterns, specific eating-related behaviors, knowledge of risks associated with current eating patterns, and concerns and feelings about specific lifestyle changes. In the subsequent follow up visit, the dietitian reviewed the 7-day food diaries to ensure nutritional adequacy and treatment compliance, and also offered recommendations for controlling caloric intake. Patients were encouraged to see an exercise instructor who designed an individualized suitable exercise regime with cardiovascular and resistance exercises for the patients to perform at home. Subjects were encouraged to perform 30-minute aerobic exercise 2-3 times a week.
Subjects in control group received simple lifestyle advice from a clinician at baseline and month 6. This was a brief discussion about the general health risk associated with OSA and importance of balanced diet. Subjects were encouraged to perform regular 30-minute exercise 2 to 3 times per week. This was to resemble routine clinical practice.
