Physical Activity Weight Loss Health-related Quality of Life | Behavioral: Intervention to increase physical activity | Not Applicable |
The proportion of Americans who are severly obese or more than 100 pounds overweight is rapidly increasing. This presents a significant public health challenge as severely obese individuals have a higher rate of comorbidities and exact a greater toll on the health care system than less obese persons. For these individuals, bariatric surgery is currently the treatment of choice for producing substantial and long-term weight loss, although outcomes vary. Low physical activity is one behavioral factor that undermines surgical success. However, structured behavioral interventions to increase physical activity in bariatric surgery patients have not been conducted.
This study involves a randomized controlled trial that compares the effects of a behavioral intervention to increase physical activity with a standard care control group on changes in physical activity among adult bariatric surgery patients with low physical activity. Eighty bariatric surgery patients will be assigned to 6 weeks of either preoperative: (1) intervention to increase physical activity or (2) standard care control. Participants in the intervention group will receive individual, face-to-face sessions involving tailored instruction in use of standard behavior change strategies such as self-monitoring, goal setting and stimulus control. The PA intervention will focus on increasing home-based walking exercise. Physical activity will be objectively measured for 7 consecutive days via accelerometry at baseline/pre-intervention, post-intervention, and 3- and 6-months postoperative follow-up. At each time point, the groups will be compared on total moderate-to-vigorous physical activity (MVPA) minutes and MVPA minutes occurring in bouts of 10 minutes or longer. This study will test whether the behavioral physical activity intervention produces greater increases in pre- and post-operative physical activity than standard care. The long-term goal of this research is to improve bariatric surgery outcomes through innovative behavioral strategies to increase physical activity.

Experimental: Activity behaviors counseling |
Behavioral: Intervention to increase physical activity
This will be a 6-week preoperative intervention to increase structured walking activity. This will be accomplished through weekly individual face-to-face sessions involving tailored instruction in use of standard behavior change strategies such as self-monitoring, goal-setting, stimulus control, etc.
