Background: During pregnancy there are physiological changes associated with the pregnancy
process that can cause urinary tract infections caused by the enlargement of the uterus, decreased
urine flow through the ureters and decreased bladder tone during pregnancy. So that healthy
pregnant women become vulnerable to serious complications in the urinary tract and will have an
impact on the mother and baby who will be at great risk of causing premature birth and low birth
weight. This study aims to estimate the magnitude of the effect of urinary tract infections in pregnant
women on premature birth and low birth weight.
Subjects and Method: This study is a systematic review and meta-analysis conducted with
PRISMA flow diagrams. Search articles through journal databases including: Google Scholar,
MEDLINE/PubMed, Science Direct, Spinger Link and Directory of Open Access Journal (DOAJ) by
selecting articles published in 2005-2021. The keywords used were “Urinary Tract Infection
Pregnancy” AND “Preterm Labor”, “Urinary Tract Infection Pregnancy” AND “Low Birth Weight”,
“Urinary Tract Infection Pregnancy” AND “Preterm Labor” AND “Low Birth Weight” AND “adjusted
Odds Ratio". Inclusion criteria included full-text articles, case-control study designs. The analysis
used logistic regression with adjusted odds ratio. Eligible articles were analyzed using the Revman
5.3 application.
Results: A total of 17 articles were reviewed in this study with a case control study design. A meta-
analysis of 11 articles showed that urinary tract infections in pregnant women increased the risk of
preterm delivery by 2.49 times compared with pregnant women without urinary tract infections
(aOR = 2.49; 95% CI = 2.04 to 3.05; p<0>infections in pregnant women can increase the risk of increasing the risk of LBW by 1.54 times
compared to pregnant women without urinary tract infections (aOR = 1.54; 95% CI = 1.24 to 1.91;
p<0>Conclusion: Urinary tract infections increase the risk of preterm birth and low birth weight.
