Association of eating behaviour with symptoms of pelvic floor disorders in middle-aged women: An observational study

Objective: To investigate associations of eating behaviour with symptoms of pelvic floor disorders (PFD), i.e., stress urinary incontinence (SUI), urge urinary incontinence (UUI), faecal incontinence (FI), constipation or defecation difficulties (CDD), and feeling of pelvic organ prolapse (POP) among middle-aged women. Design: A cross-sectional, observational study. Setting: University Research Laboratory. Sample A population sample of 1 098 Finnish women aged 47 to 55 years. Methods: Eating behaviour, demographical, gynaecological, and physical activity variables were assessed using self-report questionnaires. Simple and multiple logistic regression models were used to assess the associations of eating behaviour and symptoms of PFD. Models were adjusted with demographical, gynaecological, and physical activity variables. Main outcome measures Prevalence of symptoms of CDD, FI, POP, SUI, UUI. Results: After controlling for confounding, middle-aged women with restrictive eating style were more likely to experience the symptoms of CDD (OR 1.73, CI 1.03–2.90, p=0.039). Women with evening-oriented eating pattern were more likely to experience symptoms of UUI (OR 2.01, CI 1.32–3.07, p=0.001) while maintaining healthy eating patterns was associated with lower risk of UUI (OR 0.45, CI 0.24–0.85, p=0.014) in adjusted models. Conclusions: This study provides proof-of-concept evidence to the hypothesis that eating behaviour is associated with perceived pelvic floor disorders, particularly CDD and UUI, warranting further studies to investigate causality.
