Obesity is a major public health challenge with over 65% of U.S. adults either overweight or obese. Estimated annual costs of obesity are around $78.5 billion. Selfmonitoring is a critical skill for successful weight management. However, self-monitoring is laborintensive and compliance is often difficult. In this paper, we describe the Patient-Centered(More)
BACKGROUND To our knowledge, no studies have evaluated whether weight loss can be promoted in overweight adults through the use of an intervention that is largely based on daily SMS (Short Message Service: text) and MMS (Multimedia Message Service: small picture) messages transmitted via mobile phones. OBJECTIVE This paper describes the development and(More)
In this paper, we present PmEB, an application for mobile phones that allows users to monitor their caloric balance as a part of weight management. PmEB allows users to track their caloric balance by recording food intake and physical activity on their mobile phones. Daily reminder messages are sent via SMS messages to encourage compliance. Collected data(More)
BACKGROUND Obese adolescents are at risk for type 2 diabetes mellitus (T2DM). Obesity interventions delivered through media, such as the web and text messages [short message service (SMS)] may be beneficial when targeting obese adolescents.. METHODS A randomized controlled trial, Pace-Internet for Diabetes Prevention Intervention (PACEi-DP), compared(More)
BACKGROUND Little is known about the feasibility and acceptability of tailored text message based weight loss programs for English and Spanish-language speakers. OBJECTIVE This pilot study evaluated the feasibility, acceptability, and estimated impact of a tailored text message based weight loss program for English and Spanish-language speakers. The(More)
In 2007, the National Institutes of Health (NIH) funded the Physical Activity and Location Measurement System (PALMS) project at the University of California, San Diego. Its mission is to advance exposure biology research by developing new methods of physical activity data capture and analysis from a geospatial perspective. A key early insight was that(More)
Improved approaches and methodologies are needed to conduct comparative effectiveness research (CER) in oncology. While cancer therapies continue to emerge at a rapid pace, the review, synthesis, and dissemination of evidence-based interventions across clinical trials lag in comparison. Rigorous and systematic testing of competing therapies has been clouded(More)
Recent studies recognize that health is influenced broadly by a multitude of factors of different types, including medical, genetic, environmental, social and behavioral factors. Developing successful health interventions therefore requires taking into account all these factors as well as the interactions between them. However, intervention designers have(More)
