Asymptomatic bacteriuria (ASB) is a well-acknowledged infectious entity during pregnancy; yet its long-term implications are not well investigated. The present study aimed to test the association between maternal ASB during pregnancy and long-term offspring infectious hospitalizations. A population-based cohort analysis was conducted, comparing the incidence of long-term infectious-related hospitalizations of offspring born to mothers who were diagnosed with ASB during pregnancy, and those who did not have ASB. The study was conducted at a tertiary medical center and included all singleton deliveries between the years 1991 and 2014. Infectious morbidities were based on a predefined set of International Classification of Disease-9 codes. A Kaplan−Meier survival curve compared cumulative infectious hospitalization incidence between the groups, and a Cox regression model was used to adjust for confounding variables. During the study period, 212,984 deliveries met inclusion criteria. Of them, 5378 (2.5%) were diagnosed with ASB. As compared to offspring of non-ASB mothers, total long-term infectious hospitalizations were significantly higher among children to mothers who were diagnosed with ASB (13.1% vs. 11.1%, OR = 1.2, 95% CI 1.11–1.30, P ≤ 0.001). Likewise, a Kaplan−Meier curve demonstrated higher cumulative incidence of infectious hospitalizations among children born to mothers with ASB (log rank, P = 0.006). In the Cox regression model, while controlling for maternal age, diabetes mellitus, ethnicity, hypertensive disorders, and gestational age, maternal ASB was noted as an independent risk factor for long-term infectious morbidity in the offspring (adjusted HR = 1.1, 95% CI 1.01–1.17, P = 0.042). ASB during pregnancy increases offspring susceptibility to long-term infectious hospitalizations.
