Study summary

The prevalence of overweight in the United States Air Force (USAF) is about 22%. The objective of this study is to compare the effectiveness of a minimal contact behavioral therapy plus usual care group(MCBT+UC) using a controlled experimental comparison of usual care(UC). Subjects are USAF personnel who are 5lbs below their Maximum Allowable Weight (MAW) and heavier. The primary hypothesis is that: MCBT+UC will have significant weight loss as compared to UC.

Read the detailed description

The objective of this study is to compare the relative effectiveness of two approaches to weight management, using a controlled comparison experiment. The two approaches are: Minimal Contact Behavior Therapy Plus Usual Care (MCBT+UC) which includes an orientation meeting, provision of a self-help book, use of an interactive weight management web site for 6 months, and 2 brief motivational interviewing telephone follow-ups, plus usual care;and Usual Care (UC) which includes and orientation meeting and usual care (consisting of required USAF annual physical and fitness exam, participation in any mandatory weight loss or fitness programs, and the requirement to stay below a Maximum Allowable Weight [MAW], with penalties or separation as potential contingencies for failure to remain below MAW). The primary outcome is weight loss.Additional outcomes include body mass index, percent body fat, and waist circumference.
