Pounds Off Digitally (POD): The Use of Podcasting and Mobile Media to Promote Weight Loss
Summary
Overweight and obesity play a role in both cancer incidence and survival rates. Many people have found attending weight loss support groups to be time-intensive. Past research has shown electronic media, particularly the Web, to be effective in producing weight loss. The Web, however, lacks portability, which prevents people from accessing the information when it is convenient for them. Providing weight loss information via podcasting (audio files that may be listened to on portable audio players) may allow people to receive weight loss tips anywhere. A previous research study showed that podcasts emphasizing healthy eating and exercise can help people lose weight. This study was short-term and did not include additional social support. The purpose of this research project is to assess the effectiveness of a weight loss intervention delivered through podcasts as compared to the same podcast with added mobile media such as self-monitoring software (such as a pedometer) and support delivered via a social networking site. For this research study, the investigators will conduct a 6-month study in 104 overweight adults to determine if a podcast plus mobile media support leads to greater weight loss than a podcast alone.

Medical and Biotech [MESH] Definitions
Culture Media
Any liquid or solid preparation made specifically for the growth, storage, or transport of microorganisms or other types of cells. The variety of media that exist allow for the culturing of specific microorganisms and cell types, such as differential media, selective media, test media, and defined media. Solid media consist of liquid media that have been solidified with an agent such as AGAR or GELATIN.
Obesity, Abdominal
A condition of having excess fat in the abdomen. Abdominal obesity is typically defined as waist circumferences of 40 inches or more in men and 35 inches or more in women. Abdominal obesity raises the risk of developing disorders, such as diabetes, hypertension and METABOLIC SYNDROME X.
Culture Media, Conditioned
Culture media containing biologically active components obtained from previously cultured cells or tissues that have released into the media substances affecting certain cell functions (e.g., growth, lysis).
Communications Media
The means of interchanging or transmitting and receiving information. Historically the media were written: books, journals, newspapers, and other publications; in the modern age the media include, in addition, radio, television, computers, and information networks.
Mobile Applications
Computer programs or software installed on mobile electronic devices which support a wide range of functions and uses which include television, telephone, video, music, word processing, and Internet service.
