Schneeberger C, et al. - This cohort study was planned to compare the prevalence of asymptomatic bacteriuria (ASB) and the incidence of urinary tract infection (UTI) in pregnant women with and without diabetes mellitus (DM) or gestational DM (GDM). Researchers identified a low overall prevalence of ASB in pregnant women with and women without DM or GDM. Neither ASB nor UTI markedly differed between the groups. Data thereby did not support a routine ASB screen and treat policy in pregnant women with DM or GDM.
