Feasibility of a physical activity intervention for obese, socioculturally diverse endometrial cancer survivors.
Study Goal
The researchers aimed to evaluate the feasibility and effectiveness of a 12-week physical activity intervention, including home-based walking, on physical activity behavior, physical function, waist circumference, and quality of life in obese, socioculturally diverse endometrial cancer survivors.
Results Summary
The intervention showed large effect sizes for improvements in the six-minute walk test, waist circumference, quality of life, and walking self-efficacy compared to the control group, with participants reporting walking 118±79 minutes per week at home.
Population
Obese endometrial cancer survivors from Bronx, NY (38% non-Hispanic black, 38% Hispanic, 19% non-Hispanic white).
Effective Dosage
118±79 minutes/week of home-based walking.
Duration
12 weeks.
Interactions
None mentioned.
| Intervention | Direction | Endpoint | Population | Dosage | Impact | Claim # |
|---|---|---|---|---|---|---|
12-week physical activity intervention of behavioral counseling, physical activity and home-based walking | increase | six-minute walk test | obese, socioculturally diverse endometrial cancer survivors | 22±17m vs. 1±22m, d=1.10 | improvements | #1 |
12-week physical activity intervention of behavioral counseling, physical activity and home-based walking | decrease | waist circumference | obese, socioculturally diverse endometrial cancer survivors | -5.3±5.3cm vs. 2.6±6.7cm, d=-1.32 | improvements | #2 |
12-week physical activity intervention of behavioral counseling, physical activity and home-based walking | increase | quality of life | obese, socioculturally diverse endometrial cancer survivors | 10±12 vs. -1±11, d=0.86 | improvements | #3 |
12-week physical activity intervention of behavioral counseling, physical activity and home-based walking | increase | walking self-efficacy | obese, socioculturally diverse endometrial cancer survivors | 24±30% vs. 1±55%, d=0.87 | improvements | #4 |
PURPOSE: Determine the feasibility of a 12-week physical activity intervention for obese, socioculturally diverse endometrial cancer survivors and to evaluate whether the intervention improves physical activity behavior, physical function, waist circumference, and quality of life. METHODS: Obese endometrial cancer survivors from Bronx, NY were assigned to either a 12-week physical activity intervention of behavioral counseling, physical activity and home-based walking (n=25), or wait-list control group (n=15). Mixed-design ANOVA (2 groups×2 time points) were analyzed to determine differences between the intervention and the control for the Yale Physical Activity Survey, six-minute walk test, 30-second chair stand test, waist circumference, and Functional Assessment of Cancer Therapy-Endometrial questionnaire. Data are presented as mean±standard deviation. RESULTS: The sample was diverse (38% non-Hispanic black, 38% Hispanic, 19% non-Hispanic white). Mean Body Mass Index was 37.3±6.5kg·m(-2). Although recruitment rate was low (20% of 140 contacted), 15 of 25 participants in the intervention group attended 75-100% of scheduled sessions. Participants reported walking 118±79min/week at home. There were large effect sizes for the improvements in the six-minute walk test (22±17m vs. 1±22m, d=1.10), waist circumference (-5.3±5.3cm vs. 2.6±6.7cm, d=-1.32), quality of life (10±12 vs. -1±11, d=0.86) and walking self-efficacy (24±30% vs. 1±55%, d=0.87) compared to the control group. CONCLUSIONS: The intervention appeared feasible in this population. The results show promising effects on several outcomes that should be confirmed in a larger randomized control trial, with more robust recruitment strategies.
