RESUMO
The purpose of this study is to examine the effects of a 16-week exercise intervention (mat Pilates or belly dance) on body image, self-esteem and sexual function in breast cancer survivors receiving hormone therapy. Seventy-four breast cancer survivors were randomly allocated into mat Pilates, belly dance, or control group. The physical activity groups received a 16-week intervention, delivered 3 days a week, and 60 min a session. The control group received three education sessions. Data collection occurred at baseline, post-intervention, 6 and 12 months of follow-up with a questionnaire including body image (Body Image After Breast Cancer Questionnaire), self-esteem (Rosenberg Self-Esteem Scale), and sexual function (Female Sexual Function Index) measures. The belly dance group significantly improved body image on limitations scale in the short term and long term, the mat Pilates significantly improved body image on limitations only in the long term, and the control group significantly decreased body image on limitations in the long term. The belly dance group experienced reduced discomfort and pain during sexual relations in the short and long term. All groups showed a significant improvement in self-esteem, but orgasm sub-scale scores declined over time. No adverse events were found for any of the exercise intervention groups. Belly dance seem to be more effective than mat Pilates and control group in improving limitations of body image and sexual discomfort in the short term for breast cancer survivors.
