Abstract

For this study, 796 women maintained daily diaries for a 6-month period to evaluate risk factors of urinary tract infections: 348 with a mean age of 23 from a university cohort and 448 with a mean age of 29 from a health maintenance organization cohort. Women in the university cohort had a risk of 0.7 urinary tract infections per person year, and women in the health maintenance organization had a risk of 0.5 per person year. Identified risk factors for urinary tract infection were use of a diaphragm with spermicide (relative risk [RR] for 1, 3, and 5 days of use in the past week was 1.42, 2.83, and 5.68, respectively, in the university cohort [P<.0001] and 1.29, 2.14, and 3.54, respectively, in the health maintenance organization cohort [P=.04]), recent sexual intercourse (RR for 1, 3, and 5 days with intercourse in the past week was 1.37, 2.56, and 4.81, respectively, in the university cohort [P<.001] and 1.24, 1.91, and 2.96, respectively, in the health maintenance organization cohort [P = .002]). A history of recurring infection provided a relative risk of 5.58 in the university cohort and 2.10 in the health maintenance cohort. The authors concluded that recent sexual intercourse and recent use of diaphragm with spermicide, along with a history of recurrent urinary tract infections, provide an increased risk in this patient population.
