Clinical Trial Summary

The investigators will conduct a randomized controlled trial to evaluate the efficacy of a group-based yoga intervention to decrease the frequency and impact of urinary incontinence in ambulatory middle-aged and older women and explore potential mediators of improvement in outcomes. Women aged 45 years and older who report daily or more frequent stress-, urgency-, or mixed-type incontinence, are not already engaged in formal yoga or muscle stretching/strengthening programs, are willing to temporarily forgo other clinical treatments for incontinence, are able to walk to and use the bathroom without assistance, and meet other eligibility criteria will be recruited from multiple locations surrounding the San Francisco Bay area.

• Self-report an average of at least one incontinence episode per day on a validated voiding diary
• Self-report urgency-predominant (i.e., at least half of incontinence episodes being urgency-type), stress-predominant (i.e., at least half of episodes being stress-type), or mixed-type (i.e., an equal number of stress- and urgency-type episodes) incontinence on the screening voiding diary

Exclusion Criteria:

• Current participation in organized yoga classes or workshops, or any prior organized yoga training directed specifically at improving incontinence
• Current participation in organized physical conditioning classes involving muscle strengthening exercises (e.g., Pilates)
• Current urinary tract infection or hematuria detected by urinalysis at screening visit (women can re-present after evaluation and treatment through their usual care)
• Currently pregnant (by self-report or screening urine pregnancy test), gave birth within the past 3 months, or planning pregnancy during the study period
• Report use of medical devices (i.e. pessary) for incontinence within the past month (participants may stop use of device and re-present for study)
• Report use of bladder botox, electrostimulation, formal bladder training, or formal pelvic floor exercise training (with certified practitioners) in the past 3 months
• Report any history of prior anti-incontinence or urethral surgery (not including urethral dilation), pelvic cancer, or pelvic irradiation
• Report other surgery to the pelvis (hysterectomy, oophorectomy, vaginal surgery, bladder surgery, colon surgery) within the past 3 months
• Unable to walk 2 blocks on level ground without assistance (functional capacity < 4 metabolic equivalents)
• Unable to get up from a supine to a standing position without assistance (assessed during the screening visit)
• Report history of interstitial cystitis, bladder or rectal fistula, or congenital defect causing urinary incontinence
• Report incontinence caused by a major neurologic conditions such as multiple sclerosis, spinal cord injury, or Parkinson's disease
• Report use of medications with strong effects on urination (anticholinergic bladder medications, beta-3 agonists, tricyclic antidepressants, mirabegron, loop diuretics) within the past month
• Report starting, stopping, or changing the dose of a medication with the potential to affect anxiety or depression symptoms (i.e., selective serotonin reuptake inhibitors, anxiolytics/sedatives, antipsychotics) within the past 1 month, or plans to start, stop, or change to dose of such a medication during the study period
• Participation in another research study that involves investigational drugs or devices that could potentially confound the results of this study
• Unable to understand study procedures, complete study interviews, or and provide informed consent in English
• Report conditions that, in the judgment of the investigators, render potential participants unlikely to follow the protocol, including plans to move, substance abuse, significant psychiatric problems, or dementia
