Sex-induced cystitis--patient burden and other epidemiological features

Area of Science:

• Urology
• Infectious Diseases
• Women's Health

Background:

• Sexual intercourse is a known risk factor for uncomplicated urinary tract infections (UTIs) in women.
• The precise incidence and patient burden of recurrent UTIs linked to sexual activity remain unclear.
• Sex-induced cystitis (SIC) represents a significant subset of recurrent UTIs.

Purpose of the Study:

• To determine the rate of recurrent UTIs attributable to sexual intercourse.
• To investigate the patient burden associated with sex-induced cystitis.
• To identify demographic and behavioral risk factors for SIC.

Main Methods:

• A questionnaire-based study was conducted to gather data on UTI episodes, symptoms, and activity restrictions.
• Prevalence rates of SIC were calculated as a percentage of lower UTIs and recurrent UTIs.
• Demographic and behavioral factors were analyzed in relation to SIC occurrence.

Main Results:

• Sex-induced cystitis accounts for approximately 4% of lower urinary tract infections and 60% of recurrent UTIs.
• The condition is most prevalent in women aged 23–27, particularly those from low to median socioeconomic groups.
• Frequent sexual intercourse and condom use were identified as behavioral risk factors; E. coli was the predominant pathogen (84% of recurrent SIC).

Conclusions:

• Sex-induced cystitis is a significant cause of recurrent UTIs in young women, associated with considerable symptom duration and activity limitation.
• Understanding risk factors like sexual frequency and condom use is crucial for prevention strategies.
• E. coli is the primary causative agent in recurrent SIC, highlighting the need for targeted antimicrobial approaches.
