Abstract

Objective: To compare maternal and perinatal outcomes between day-time and evening/night-time births in a low-risk population.

Material and methods: The present study had a retrospective and cross-sectional design. The study recruited 421 pregnant women admitted for spontaneous or induced labor, with singleton, full-term pregnancy, without comorbidities, and with birthweight between 2,500 and 4,499 g. Maternal data, including severe bleeding, need for blood transfusion, puerperal infection, and admission to the intensive care unit, and neonatal data including birthweight, Apgar scores at first and fifth minute, oxygen administration, resuscitation, admission to the neonatal care unit, infection, and blood transfusion, were evaluated. Univariate and multivariate analysis and calculation of the prevalence ratio (PR) were performed with a 95% confidence interval (CI).

Results: There were no differences in factors of maternal morbidity between delivery times. Newborns delivered during the evening/night-time had a higher prevalence of infection (15.3% vs 7.9%, p=0.019, PR: 2.11, CI 95% 1.13-3.93) and hospitalization in the neonatal care unit (25.8% vs 10.4%, p<0.001, PR: 2.99, CI 95% 1.76-5.10). There was no difference in other perinatal morbidities examined.

Conclusion: Evening/night-time births were associated with a higher prevalence of infection and the need for admission to an intensive care unit.

Keywords: Evening/night-time; adverse maternal/perinatal outcomes; delivery; labor.
