Feasibility and effectiveness of a lifestyle intervention program in obese endometrial cancer patients: A randomized trial

ObjectiveThe majority of endometrial cancer survivors (ECS) are obese and at risk for premature death. The purpose of this study was to assess feasibility of a lifestyle intervention program for promoting weight loss, change in eating behaviors, and increased physical activity in obese ECS.Study designEarly stage ECS (n = 45) were randomized to a 6-month lifestyle intervention (LI; n = 23) or usual care (UC; n = 22). The LI group received group and individual counseling for 6 months. The primary endpoint was weight change. Secondary endpoints were physical activity, [Leisure score index (LSI)] and nutrient intake (3-day food records). Quantitative vitamin C and folate intake were used to assess fruit/vegetable intake.ResultsRecruitment was 29%, adherence (LI group) was 73% and 84% of participants completed follow-up assessments. At 12 months, the intervention group lost 3.5 kg compared to a 1.4 kg gain in the control group [mean difference = − 4.9 kg; 95% CI: − 9.0 to − 0.9 kg; p = .018] and had an increased LSI score of 16.4 versus − 1.3 in the control group from baseline [mean group difference = 17.8; 95% CI = 7.1 to 28.4; p = .002]. There were no differences in vitamin C and folate intake. The LI group had lower intake of kilocalories, although differences were not significant.Conclusion(s)A lifestyle intervention program in obese ECS is feasible and can result in sustained behavior change and weight loss over a 1-year period.
