Description of intervention(s) / exposure
a) Participant group of interest: Australian Performing Artists (over the age of 18 years).

b) The sample will be selected via a non-probability sampling technique, recruiting through performing arts schools, and professional companies with approval from the managers or Artistic Directors. All performing artists will be invited to participate. The aim of this approach is to attract eligible participants directly. The administration team at each performing arts company will distribute the questionnaire to their artists via email and/or newsletter with a link to the questionnaire. The questionnaire will also be advertised through social media (Facebook, LinkedIn, Twitter, Instagram) to performing artists, through targeted advertising strategies using hashtags and posting in relevant groups. Interested performing artists can email the lead researcher if they have queries and the questionnaire will be able to be completed after providing informed consent, which will be embedded within the questionnaire.

c) Outcomes to be assessed:

Part 1:
• To investigate the prevalence of pelvic floor disorders in Australian performing artists.
• To identify the factors associated with the presence of pelvic floor disorders in performing artists.
• To explore the impact pelvic floor disorders have on performing artists’ performance, training and everyday activities.
Part 2:
• To explore if there are barriers to performing artists accessing care for the management of pelvic floor disorders.

These outcomes will be assessed via completion of questionnaires.

d) Time commitment: Approximately 30 minutes

e) The questionnaire will be completed via an online link

f) Cross-sectional study

Statistical methods / analysis
This study is cross-sectional in design, using an anonymous online questionnaire that will be purpose-designed and include sections developed by the expert research team as well as validated outcome measures where they exist.

Sociodemographic and health data questions will be developed by the expert research team with guidance from a previously published questionnaire (Dakic et al., 2021). Participant characteristics will include age, body-mass index (BMI), education level, sex, and gender. Medical and pelvic health data will include pelvic health conditions, previous pelvic surgeries, and obstetric history, as these factors may independently impact the odds of developing PFD.

Piloting:
The questionnaire will be piloted with performing artists and this piloting phase will allow the research team to collect feedback on understanding, clarity, length, and layout and make amendments accordingly.

Sample size:
The proposed sample size is 384, based on the conservative prevalence of 20% (urinary continence and/or anal incontinence) (Skaug et al., 2021) a conservative precision estimate of 4% and a confidence interval of 95% (Pourhoseingholi et al., 2013). Given that 2011 national data reported up to 16,000 Australians were employed as performing artists (this figure does not include amateur artists), the proposed sample size is feasible (Australian Bureau of Statistics., 2014). The sample will be selected via a non-probability sampling technique, recruiting through performing arts schools, and professional companies with approval from the managers or Artistic Directors. All performing artists will be invited to participate. The aim of this approach is to attract eligible participants directly. The administration team at each performing arts company will distribute the questionnaire to their artists via email and/or newsletter with a link to the questionnaire. The questionnaire will also be advertised through social media (Facebook, LinkedIn, Twitter, Instagram) to performing artists, through targeted advertising strategies using hashtags and posting in relevant groups. Interested performing artists can email the lead researcher if they have queries and the questionnaire will be able to be completed after providing informed consent, which will be embedded within the questionnaire.

Analysis Plan:

REDCap data will be extracted and collated into an excel spreadsheet for data analysis. The proposed analysis will be completed using SPSS Statistical Software (version 28) and will involve both descriptive analysis and inferential statistics.

Primary performing art genre will be analysed as per the questionnaire and also collapsed into large artistic categories: dance, music, circus, and theatre for analysis. Sociodemographic variables will be presented as numbers with percentages or means with standard deviation (SD) or median (IQR) if not normally distributed. Prevalence of each PFD (lower urinary tract symptoms, bowel symptoms, pelvic floor pain, pelvic organ prolapse (POP), and dyspareunia) will be reported as frequency and percentage and comparisons between artistic group with PFD (yes/no) explored using chi squared analysis. Associated factors will be explored using multivariate binary logistic regression (PFD yes/no) and reported as odds ratio with 95% confidence intervals with categorical factors, such as performing arts type, gender, parity and activity levels and continuous covariates for example BMI explored. Alpha will be set at 0.05.

Descriptive analysis will be used to report on compensatory strategies, bother and impact of PFD in performing artists, and part two of the questionnaire.

Summary
Brief summary
Introduction
The pelvic floor has a critical role in resisting intra-abdominal pressure and ground reaction force to maintain pelvic organ support and continence. Pelvic floor disorders (PFD), such as pelvic organ prolapse, urinary incontinence, or pelvic floor pain may arise when this system is compromised. Performing artists are a unique population group that may be exposed to factors potentially provocative of PFD and symptoms. Pelvic floor disorders and symptoms are posited to negatively impact exercise and performance participation. The purpose of this study is to describe the prevalence, impact and factors associated with PFD in performing artists.

Methods and analysis
This study is a cross-sectional survey, with a proposed sample size of at least 384 performing artists. Questionnaires will be distributed to performing arts organisations (recreational, professional and schools) across Australia via REDCap and all data will be anonymised. Data will be collected on the primary outcome, prevalence of PFD, using existing validated questionnaires. Data will also be collected on the impact PFD have on performance, training, and everyday activities and what factors that may be associated with PDF and symptoms (secondary outcomes).
Data will be analysed and reported as frequency and percentage for prevalence. Associated factors will be explored using binary logistic regression, and descriptive analysis will be used to report on the impact of PFD in performing artists.

Ethics and dissemination
The study is deemed low-risk and La Trobe University ethics approval will be sought prior to commencement. Results will be disseminated via peer-reviewed publications, presentations at national and international conferences, and summary findings will be provided to Australian performing arts organisations and companies.

Data sharing statement
Will individual participant data (IPD) for this trial be available (including data dictionaries)?
No
No/undecided IPD sharing reason/comment
Despite the anonymous nature of the questionnaire, an individual may be identifiable through the way they answer the questionnaire. Therefore, to maintain participant confidentiality IPD will not be available, particularly given the personal nature of the questions being asked.
