Which of the following factors could lead to an increased risk of urinary incontinence?

High caffeine intake is linked to an increased risk of urinary incontinence due to its diuretic properties, which can lead to increased urine production. Caffeine stimulates the bladder, reducing its capacity to retain urine and potentially increasing the urgency and frequency of urination. This can especially be a concern for individuals who consume large amounts of caffeine through drinks like coffee, tea, and sodas.

In contrast, increased physical activity typically promotes better pelvic floor health and may actually help improve bladder control, while weight loss often reduces pressure on the bladder and could alleviate symptoms. Frequent hydration itself is important for urinary health, and while it might sound counterintuitive, staying well-hydrated helps to promote healthy bladder function and can prevent irritation that might occur from concentrated urine.
