Innovative Approaches to Diet, Exercise and Activity

Summary

The prevalence of obesity in young adults has been increasing, and excessive body weight have been linked to numerous chronic conditions including cardiovascular disease, diabetes, many forms of cancer, and numerous musculoskeletal problems. This study will focus of the development and evaluation of interventions that may be appropriate for young adults (age 18-35 years) to improve weight loss outcomes following a 24 month intervention. The primary aim of this study is to examine whether an enhanced weight loss intervention (EWLI) that includes technology components results in improved weight loss in young adults (18-35 years of age) compared to a standard behavioral weight loss intervention (SBWP) over a period of 24 months. Eligible participants will also be assessed for body composition, body fat distribution, fitness, physical activity, dietary intake, and behavioral/psychosocial measures that may be predictive of behavior change. Assessments will occur at 0, 6, 12, 18, and 24 months. Subjects will participate in a 24 month behavioral weight loss program that includes a reduction in energy intake and moderate-to-vigorous intensity exercise (progressively increasing from 100 to 300 minutes per week). The technologies added to EWLI are text messaging, a wearable device that provides feedback on physical activity, and access to a website to monitor dietary behaviors.

Interventions

BEHAVIORAL

Standard Behavioral Weight Loss Intervention

Subjects in this group will receive our standard behavioral weight control program that is delivered in an in-person group-based format. At month 7 subjects will also be given access to a study website to monitor eating and activity behaviors, and to have electronic access to standardized intervention materials. At month 7 subjects will also receive targeted study-related text messages that otherwise would have been provided in paper format.

BEHAVIORAL

Enhanced Weight Loss Intervention

Subjects in this group will participate in a weight loss intervention that includes technology enhancements. These enhancements will include the addition of intervention specific targeted and tailored text messaging and the BodyMedia Fit System® beginning at Month 7. At month 7 subjects in EWLI will also receive the same targeted study-related text messages provided to SBWP that otherwise would have been provided in paper format.
