Which of the following is a risk factor for cystitis?

Being sexually active is indeed recognized as a risk factor for cystitis, particularly in women. This is due to the anatomical structure of the female urinary tract, which makes it easier for bacteria from the vaginal and rectal areas to enter the urethra during sexual activities. This can lead to urinary tract infections (UTIs) and subsequently cystitis, characterized by inflammation of the bladder.

On the other hand, regular exercise, high fluid intake, and daily fruit consumption are generally not associated with an increased risk of cystitis. In fact, high fluid intake can actually help flush out bacteria from the urinary system, reducing the likelihood of infections. Regular exercise is beneficial for overall health and helps improve immune function. Likewise, consuming fruits can contribute to hydration, provide vitamins, and support a healthy diet, all of which can further help in maintaining urinary tract health.
