Additional Information

Official title Remote Delivery of Weight Management by Phone and Social Media
Principal investigator Joseph Donnelly, PhD
Description Obesity is a major public health issue as 68% of the US population is either overweight or obese. Weight loss and weight loss maintenance is difficult. Traditionally, successful weight loss programs are weekly behaviorally-based clinics which utilize a combination of calorie restriction and physical activity. Traditional "face to face" weekly meetings may not be feasible for everyone. An alternative to provide weight loss and weight maintenance created by KUMC researchers uses weekly group phone conference calls. While this method produced equal weight loss with fewer burdens to participants when compared to the traditional "face to face" format, weight regain during maintenance was still high. This study will investigate a new delivery method (social media platform "Facebook") compared to the group phone conference calls. In the social media platform participants will be able to socialize with other participants in their group by commenting on posts from other participants or posting messages themselves. Social media delivered programs have potential to be a more a cost-effective approach to reach a large group of individuals. Participants who are eligible and decided to be in this study will take part in study related activities for 6 months.
