Background
The impact of anal incontinence on women’s sexual function is poorly understood.
Objective
To investigate the relationship between anal incontinence and sexual activity and functioning in women.
Design
Cross-sectional study.
Settings
Community-based integrated healthcare delivery system.
Patients
2,269 ethnically-diverse women aged 40 to 80 years.
Main Outcome Measures
Self-administered questionnaires assessed accidental leakage of gas (flatal incontinence) and fluid/mucus/stool (fecal incontinence) in the past 3 months. Additional questionnaires assessed sexual activity, desire and satisfaction, as well as specific sexual problems (difficulty with arousal, lubrication, orgasm, or pain). Multivariable logistic regression models compared sexual function in women with 1) isolated flatal incontinence, 2) fecal incontinence (with or without flatal incontinence), and 3) no fecal/flatal incontinence, controlling for potential confounders.
Results
Twenty-four percent of women reported fecal incontinence and 43% reported isolated flatal incontinence in the prior 3 months. The majority were sexually active (62% of women without fecal/flatal incontinence, 66% with isolated flatal incontinence, and 60% with fecal incontinence; p=0.06). Compared to women without fecal/flatal incontinence, women with fecal incontinence were more likely to report low sexual desire (OR:1.41 [CI:1.10–1.82]), low sexual satisfaction (OR:1.56 [CI:1.14–2.12]), and limitation of sexual activity by physical health (OR:1.65 [CI:1.19–2.28]) after adjustment for confounders. Among sexually active women, women with fecal incontinence were more likely than women without fecal/flatal incontinence to report difficulties with lubrication (OR:2.66 [CI:1.76–4.00]), pain (OR:2.44 [CI:1.52–3.91]), and orgasm (OR:1.68 [CI:1.12–2.51]). Women with isolated flatal incontinence reported similar sexual functioning to women without fecal/flatal incontinence.
Limitations
Cross-sectional design prevented evaluation of causality.
Conclusions
While most women with anal incontinence are sexually active, those with fecal incontinence are at high risk for several aspects of sexual dysfunction. This indicates that sexual function is important to women with anal incontinence and should be prioritized during therapeutic management.
