    Abstract:
    OBJECTIVE: More patient-centered programming is essential for endometrial cancer (EC) survivors needing to lose weight to reduce cardiovascular disease risk (CVD). The purpose of this study was to improve self-efficacy (SE) and quality of life (QOL) using a lifestyle intervention program designed for weight loss. METHODS: Overweight and obese early-stage EC survivors, n = 75, were randomized into two groups: 1) Survivors of Uterine Cancer Empowered by Exercise and Healthy Diet (SUCCEED), a six-month lifestyle intervention or 2) a usual care group (UC). Participants completed the Weight Efficacy Lifestyle Questionnaire (WEL) to assess SE and the Functional Assessment of Cancer Therapy-General (FACT-G) to measure QOL, and their body mass index (BMI) was calculated at baseline, 3, 6, and 12 months. Mixed, repeated-measures ANCOVA models with baseline covariates were employed using SPSS 20.0. RESULTS: Positive effects in every WEL domain, including the total score, were statistically significant in the SUCCEED group versus the UC group. A linear regression model demonstrated that, if BMI decreased by 1 unit, the total WEL score increased by 4.49 points. Significant negative correlations were found in the total WEL score and a change in BMI of R = -0.356 (p = 0.006). Between-group differences in the FACT-G were significant from baseline in the fatigue domain at three months (p = .008) and in the physical domain at six months (p = .048). No other significant differences were found. CONCLUSION: Overall, this study shows promise for targeted interventions to help improve SE, thus improving BMI.
