MARTINEZ RAMOS, Alfredo Jhonatan et al. Case control study on the threat of preterm delivery and its risk factors in pregnant women in a referral hospital in Peru during the COVID-19 pandemic. Mem. Inst. Investig. Cienc. Salud [online]. 2022, vol.20, n.1, pp.39-45. ISSN 1812-9528.  https://doi.org/10.18004/mem.iics/1812-9528/2022.020.01.39.

The objective of the present study was to determine the relationship between the threat of preterm birth and its risk factors in pregnant women treated at a referral hospital in Peru during the covid-19 pandemic, with emphasis on urinary tract infection. An unpaired case-control type design was carried out, with a representative sample including 92 cases and 92 controls selected by simple random probabilistic sampling. A logistic regression model was carried out for urinary tract infection and threat of preterm birth for calculating the Odds Ratio and 95% confidence intervals. An association was reported for the threat of preterm birth with the variables: elderly pregnant woman 3.159 (95% CI 1.66 - 6.02), less than six prenatal controls 3.9 (95% CI 2.084 - 7.298), parity 0.353 (95% CI 0.180 - 0.691), history of preterm birth 2843 (95% CI 1253-5639) and urinary tract infection 2843 (95% CI 1253-5639). It is concluded that urinary tract infection is associated with the threat of preterm birth in pregnant women treated in a Peruvian reference hospital.
