A retrospective analysis of 24,000 births found the prevalence of UTI during pregnancy to be 28.7% in whites and Asians, 30.1% in blacks, and 41.1% in Hispanics. When socioeconomic status is controlled for, no significant interracial differences seem to exist. A survey-based analysis of self-reported UTI found similar trends. This study also considered Native American women and found the highest prevalence of UTI in this population (24.2%) as compared with Asian (10.3%), white (16.6%), Hispanic (18.3%), and black (20.3%) women.

UTI is associated with preterm delivery in persons of all races. The adjusted odds ratio in infants with very low birth weight is 2.8 in blacks and 5.6 in whites, adjusted for parity, body mass index, maternal age, marital status, cigarette smoking, education, and prenatal care. The overall relative risk of bacteriuria in blacks or whites is estimated at 1.5-5, and the relative risk of preterm birth in women with bacteriuria is 1.8-2.3.
