Pragmatic Obstructive Sleep Apnea Weight Loss Trial Assessing Effectiveness and Reach

Intervention Arm: Usual Care plus a lifestyle behavior change intervention aimed at improving eating habits and increasing physical activity. The lifestyle behavior change intervention encourages participants to gradually achieve and maintain a 5-10% loss of baseline body weight and at least 150 minutes of moderate-intensity physical activity, such as brisk walking, each week. The lifestyle intervention program consists of watching one video, completing corresponding written self-guided learning materials, and tracking food intake and physical activity each week for the first 12 weeks, then working through 10 additional written handouts and continued food and activity tracking for the next nine months. Intervention participants will have access to a lifestyle coach as desired for the full 12-month intervention period.
