Health behavior and urinary tract infection in college-aged women

We conducted a case-control study to examine the associations between various behavioral risk factors and urinary tract infection among college-aged women. Cases were collected from a University Health Service, and were compared to Health Service controls and to a population-based control group. Sexual intercourse, diaphragm use, and urinating after sexual intercourse were each associated with urinary tract infection (UTI). The magnitude of the association of diaphragm use with UTI was reduced when urination habits around sexual intercourse were considered.
