What was measured

Quality of life is assessed using the EuroQol 5-Dimension 5-Level questionnaire (EQ-5D-5L), a standardized instrument that measures health status across five dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each dimension is rated on 5 levels: No problems, Slight problems, Moderate problems, Severe problems and Extreme problems Responses are combined into a 5-digit health state, which is converted into a single summary index score. EQ-5D Index range: 0 to 1. Higher scores indicate better quality of life

Analysis population: The number of participants analyzed differ between baseline and 12 months due to withdrawal by participant or loss to follow up.

Groups in this outcome

Project 1: Diet-Exercise

Participants will receive and participate in web-based sessions that focus on diet for 6 months, followed by exercise for another 6 months. Participants will be encouraged to track their diet and weight for the first 6 months and to log their data in the intervention website, during the second 6 months they will be asked to log their physical activity data (minutes and step counts). Tailored feedback and goal recommendations will be provided through the website. Participants will also receive access to resources for relevant behavioral topics. All participants will be invited to participate in the secret Facebook group for the project (though participation is optional).

Project 2: Exercise-Diet

Participants will receive and participate in web-based sessions that focus on diet for 6 months, followed by exercise for another 6 months. Participants will be encouraged to track their diet and weight for the first 6 months and to log their data in the intervention website, during the second 6 months they will be asked to log their physical activity data (minutes and step counts). Tailored feedback and goal recommendations will be provided through the website. Participants will also receive access to resources for relevant behavioral topics. All participants will be invited to participate in the secret Facebook group for the project (though participation is optional).

Project 3: Combined Diet and Exercise

Participants will receive the diet and exercise content simultaneously in combined web-based sessions. Participants will receive and participate in web-based sessions that focus on diet and exercise for 12 months. Participants will be encouraged to track their diet, weight and physical activity data (minutes and step counts). Tailored feedback and goal recommendations will be provided through the website. Participants will also receive access to resources for relevant behavioral topics. All participants will be invited to participate in the secret Facebook group for the project (though participation is optional).
