Background and Objectives: Pregnancy is one of the most important and risky periods in
mothers and the fetus life, which plays a key role in health and social activity of the person,
family and community. This study is trying to see if there is a relation between increasing
weight and urinary tract infection (UTI) in pregnancy by using the open nested case‑control
study in the city of Shahrekord. Materials and Methods: In a nested case‑control study,
one cohort including 832 patients was examined until week 26 to 30 of pregnancy and their
UTIs were studied. The required information was collected by examining the health records
of pregnant women and completion of the data registration forms. Data collection was
controlled by using SPSS and analyzed by using an independent t‑test, Chi‑square test,
Pearson correlation and logistic regression. Results: According to the results of the cohort
study with 832 individuals, average weight gain of the group with a UTI was 11.13 ± 3.9 kg
and it was 10.63 ± 3.9 kg in the group without UTI, showing no statistically significant
difference (P = 0.245). According to the results, genitourinary problems had the highest
predictive value for UTIs and the numbers of infertility and the childbirth variables were in
the second and third positions, respectively. Conclusion: According to the results study
we can conclude that screening and treatment of UTIs have been on time and appropriate
in health systems of the city of Shahrekord which have lead to the reduction of infant and
maternal diseases even with the condition in having no UTI, and continuing this process for
screening and treatment is recommended.
