Risk factors for urinary tract infection

Area of Science:

• Epidemiology
• Urology
• Public Health

Background:

• Urinary tract infections (UTIs) are common among college-aged women.
• Behavioral factors are suspected contributors to UTI development.
• Understanding risk factors is crucial for prevention strategies.

Purpose of the Study:

• To investigate the association between behavioral factors and the risk of urinary tract infection (UTI).
• To identify specific behaviors that may increase UTI susceptibility in college women.

Main Methods:

• A case-control study conducted between 1982-1983.
• Participants included college women from a student health service.
• Cases: 43 women with culture-confirmed UTIs. Controls: 149 women with upper respiratory infections and 227 women from gynecology clinics.

Main Results:

• Sexual intercourse was confirmed as a significant risk factor for UTIs.
• A dose-response relationship was observed between coital frequency and UTI risk.
• Diaphragm use showed a significant association with increased UTI risk (ORs 3.0, 2.3), even after adjusting for coital frequency.

Conclusions:

• Sexual activity and diaphragm use are identified as key behavioral risk factors for urinary tract infections in college women.
• Findings suggest that specific contraceptive methods and frequency of intercourse warrant consideration in UTI prevention efforts.
• Commonly believed factors like fluid intake and clothing type were not associated with UTI risk in this study.
