Which demographic is most commonly affected by stress incontinence?

• A. Adolescent girls
• B. Middle-aged women with several vaginal deliveries
• C. Men with BPH
• D. Children

Answer: (B)

Stress incontinence happens when increases in abdominal pressure—like coughing, sneezing, or lifting—overwhelm the pelvic floor’s ability to support the urethra. The most common way this support weakens is pelvic floor damage from vaginal childbirth. Having several vaginal deliveries stretches and weakens the muscles and connective tissue that keep the urethra closed, and age-related tissue changes can worsen this. That combination makes middle-aged women with multiple deliveries the group most affected. Adolescent girls and children typically have incontinence due to immature bladder control or other non-pelvic-floor factors, not the pelvic floor weakness that causes stress incontinence. In men with BPH, leakage is usually from bladder outlet obstruction and overflow rather than from pelvic floor-related leakage with exertion, so it’s not the classic pattern of stress incontinence.
