Final answer:
Female gender, frequent sexual intercourse, and postmenopausal status are considered risk factors for cystitis or bladder infection.
Step-by-step explanation:
Several risk factors contribute to the development of cystitis or bladder infection. These include:
- Female gender: Women are more prone to bladder infections than men due to their shorter urethra and its proximity to the anus, which can lead to bacterial contamination.
- Frequent sexual intercourse: Sexual activity can introduce bacteria into the urinary tract, increasing the risk of infection.
- Postmenopausal status: After menopause, the decrease in estrogen levels can lead to changes in the urinary tract that make women more susceptible to infections.
Therefore, A) Female gender, B) Frequent sexual intercourse, and E) Postmenopausal status are all considered risk factors for cystitis or bladder infection.
