Physical Activity Behavioral Intervention in Obese Endometrial Cancer Survivors

The Effectiveness of a Comprehensive Physical Activity Behavioral Intervention on Underserved Diverse Obese Endometrial Cancer Survivors

This randomized clinical trial studies a physical activity behavioral intervention in obese endometrial cancer survivors. Learning about physical activity behavior while participating in a fitness class may help increase physical activity and improve the quality of life of obese endometrial cancer survivors.

PRIMARY OBJECTIVES: I. To determine the effect of a 12-week behavior/exercise intervention on moderate-vigorous physical activity (> 150 minutes) among ethnically diverse endometrial cancer survivors. SECONDARY OBJECTIVES: I. To determine the effects of a 12-week behavior/exercise intervention on body composition among ethnically diverse endometrial cancer survivors. TERTIARY OBJECTIVES: I. To determine the effects of a 12-week behavior/exercise intervention for ethnically diverse endometrial cancer survivors on physical function and quality-of-life. II. To determine the most important behavioral variables for predicting physical activity adherence. III. To determine the most significant facilitators and barriers to adherence during the 12-week intervention. IV. To compare the thematic differences between high-adherence and low-adherence participants and qualitatively assess the strengths and weaknesses of the 12-week intervention. OUTLINE: Participants are randomized to 1 of 2 groups GROUP I: Participants partake in 30 minutes of group discussions regarding physical activity behavior followed by 60 minutes of moderate-intensity exercise comprised of 5 minutes warm-up, 25 minutes cardiovascular training, 20 minutes of resistance training exercises using body weight and exercise band, and 10 minutes of cool-down and stretching once weekly for 12 weeks. Participants also complete a brisk walk for 90 minutes per week outside of class for 12 weeks. GROUP II: Participants receive a handout indicating the importance of physical activity and improved nutrition for health outcomes. After 12 weeks, patients are invited to participate in the physical behavior intervention as in Group I. After completion of study, participants are followed up at 12 weeks.

Multiple logistic regression analysis will be used to examine the association of the Social Cognitive Theory behavior variables to physical activity, adjusting for potential confounders.

Will be analyzed using student t-test. When the data are non-normal, investigators will use appropriate nonparametric tests.
