Hypothesis / aims of study
Non-conventional modalities have been studied to address the physical and psychological symptoms of menopause. While the mental health benefits of physical exercise are well-established [1], few studies have investigated exercise for sexual function during menopause. This study aims to analyze the short and long-term effects of Jazz Dance compared to a control group on the sexual function of menopausal women, hypothesizing that the Jazz Dance intervention group will experience greater benefits in sexual function compared to the control group post-intervention.
Study design, materials and methods
A two-arm randomized clinical trial (Jazz Dance Intervention Group (JDIG) (n=23) and Control Group (CG) (n=24)) involving 47 women (average age 53.41±2.8 years) was conducted following CONSORT (Consolidated Standards of Reporting Trials) guidelines. The JDIG underwent a sixteen-week Jazz Dance protocol developed and published specifically for menopausal women [2], while the CG received monthly follow-up calls. Data collection occurred at baseline, post-intervention, six-month follow-up, and twelve-month follow-up. Instruments included a self-administered questionnaire covering personal and clinical questions (developed by the authors) and the Female Sexual Function Index. Descriptive statistics were used for baseline data including percentages, means, and standard deviations, with Chi-square and Fisher's exact tests used for group comparisons. Generalized Estimating Equation (GEE) with post hoc analysis of the Least Significant Difference assessed group x time interaction and isolated variable effects. Intent-to-Treat (ITT) analysis was conducted between exercise and control groups, with adherence to protocol analysis performed to evaluate potential bias from loss to follow-up or intervention protocol changes (significance level set at p < 0.05).
Results
Participant characteristics were homogeneous. The average participant age was 53.41 ± 2.8 years, with an average duration of amenorrhea of 3.35 ± 1.58 years. Regarding sexual function, the orgasm domain showed improvement in the JDIG between baseline and post-intervention to twelve-month follow-up (p=0.012 and p=0.012). Satisfaction domain scores increased between baseline and six and twelve-month follow-ups (p=0.050 and p=<0.001, respectively), and between post-intervention and six and twelve-month follow-ups (p=0.045 and p=0.003, respectively). The desire domain demonstrated higher scores in the JDIG (p=0.018), with improvement from baseline to six and twelve-month follow-ups (p=0.006 and p=<0.001, respectively) in the satisfaction domain.
Interpretation of results
With 85.62% participant adherence to the protocol and considering that is a non-invasive intervention with no complications, Jazz Dance emerged as a safe non-pharmacological therapy for this population. Dance has evidenced biopsychosocial benefits in older women [3], and in this study, Jazz Dance characteristics seemed to reflect in sexual function, offering an alternative for managing domains such as desire, satisfaction, and orgasm in the long term. These findings are significant considering the lack of studies addressing this intervention for sexual function outcomes in menopausal women, motivating further research with longer intervention durations for even more significant results. Other interventions like belly dance, focusing on pelvic movements, have shown positive outcomes for middle-aged women. Therefore, future studies could explore dance protocols with specific emphasis of this body part to benefit pelvic and pelvic floor structures.
