<p>Abstract</p> <p>Background</p> <p>To examine the effects of a 6 month lifestyle intervention on quality of life, depression, self-efficacy and eating behavior changes in overweight and obese endometrial cancer survivors.</p> <p>Methods</p> <p>Early stage endometrial cancer survivors were randomized to intervention (n = 23) or usual care (n = 22) groups. Chi-square, Student's t-test and repeated measures analysis of variance were used in intent-to-treat analyses. Outcomes were also examined according to weight loss.</p> <p>Results</p> <p>Morbidly obese patients had significantly lower self-efficacy, specifically when feeling physical discomfort. There was a significant improvement for self-efficacy related to social pressure (p = .03) and restraint (p = .02) in the LI group. There was a significant difference for emotional well-being quality of life (p = .02), self-efficacy related to negative emotions (p < .01), food availability (p = .03), and physical discomfort (p = .01) in women who lost weight as compared to women who gained weight. Improvement in restraint was also reported in women who lost weight (p < .01).</p> <p>Conclusion</p> <p>This pilot lifestyle intervention had no effect on quality of life or depression but did improve self-efficacy and some eating behaviors.</p> <p>Trial Registration</p> <p><url>http://www.clinicaltrials.gov</url>; NCT00420979</p>
