Introduction and hypothesis: Pregnancy is a risk factor for urinary tract infection (UTI), and it has been shown that frequent urine voiding was a protecting factor against UTI for nonpregnant female cleanroom workers. We conducted a study to evaluate whether these findings also apply to pregnant women. Methods: We recruited female workers in an industrial park who received an annual health examination between August 1 and September 31, 2003. From each participant, we collected a urine sample and obtained information through a questionnaire. Results: A total of 2,062 workers,including 118 pregnant and 1,944 nonpregnant women, participated in the study. Pregnancy was a significant risk factor for both symptomatic (odds ratio [OR]=6.33) and asymptomatic (OR=2.13) UTIs. Urine voiding three or more times during a shift was a significant protective factor for asymptomatic UTI (OR=0.40). Conclusions: UTI is common among pregnant cleanroom workers,and frequent voiding appears to be a protecting factor.
