HERNANDEZ B., Olivia  and  GRUPO GESTACOVID et al. COVID-19 and pregnancy in Chile: preliminary report of the GESTACOVID multicenter study. Rev. chil. obstet. ginecol. [online]. 2020, vol.85, suppl.1, pp.S75-S89. ISSN 0048-766X.


In Chile, effects of the SARS-CoV-2 infection in pregnant women are unknown. GESTACOVID is a multicenter collaborative study including pregnant women and those in the postpartum period (until 42 days) who have had COVID-19. The purpose of this study is to report our preliminary results describing the clinical impact of COVID-19 in pregnant women, the associated risk factors and perinatal results.


Descriptive cohort study including 661 patients between April 7th and July 6th, 2020, in 23 hospitals. Demographical, comorbidities, clinical and diagnostic characteristics of COVID-19 disease and maternal and perinatal outcomes were analyzed.


Pregnant women with COVID-19 admitted to the hospital were more likely to have chronic hypertension [10% vs 3%; OR=3.1 (1.5–6.79); p=0,003] and diabetes type 1 and 2 [7% vs 2%; OR=3.2 (1.3–7.7); p=0.009] than those with outpatient management. A body mass index of >40 kg/mt2 was associated with two-fold higher risk of hospitalization [OR=2.4 (1.2–4.6); p=0.009]. Almost half of patients (54%) were delivered by cesarean section, and 8% of the medically indicated deliveries were due to COVID-19. So far, 38% of the patients are still pregnant. Among 316 newborns, there were 21 positive PCR tests (6.6%), mostly from asymptomatic mothers undergoing universal screening.


Pregnant women with COVID-19 and comorbidities such as diabetes, chronic hypertension and morbid obesity need a close follow up and should be a matter for further research. Vertical transmission of COVID-19 should be thoroughly studied to define the mechanisms and type of infection involved.
