Cystitis is uncommon in young children and teenagers. Pregnancy increases the risk of infection because of hormonal changes in women and because the enlarging uterus restricts the flow of urine and creates urinary stasis and bacteria proliferation. Men, on the other hand, secrete prostatic fluid that serves as an antibacterial defense. As men age past 50, however, the prostate gland enlarges, which increases the risk for urinary retention and infection. As women age, vaginal flora and lubrication change; decreased lubrication increases the risk of urethral irritation in women during intercourse. By age 70, prevalence is similar for men and women.
IC occurs primarily in women, and is more common in Jewish women. Prevalence is higher among U.S. women than those in Europe and Japan. Although at one time IC was considered a disease of menopause, experts note that it is most common in middle-aged rather than older women.
