The relationship between oral, the kidney and urinary tracts infections and preterm delivery in pregnant women admitted to educational hospitals, Isfahan, Iran

Objective (s): The most common cause of death and mortality of infants is preterm labor. The identification of factors associated with preterm labor will reduce preterm infant mortality. This study aimed to determine the relationship between preterm delivery and oral, kidney and urinary tracts infections in pregnant women Methods: This was a case-control study that carried on the 198 pregnant women (66 pregnant women with premature labor as case group and 132 pregnant women with term delivery as control group) in selected hospitals in Isfahan, Iran, in 2018. For data collection we used demographic and fertility questionnaire, and the Holbrook standard checklist. Data were analyzed using descriptive statistics and t–test, chi-square, Mann-Whitney, Fisher’s exact test, logistic regression. Results: The results showed that there was no significant relationship between preterm labor and kidney, urinary tracts infections (p=0.626). While the logistic regression showed significant association between the onset of uterine contractions (preterm birth) and of the mouth and teeth infections (p=0.012) Conclusion: The findings suggest that there is relationship between preterm deliveries and oral infections. Therefore, it is recommended that preventive necessary measures be taken or treat oral infections faster in women before and during pregnancy.
