Factors associated with COVID-19 severity among Brazilian pregnant adolescents: a population-based study

“…Among the signs and symptoms presented by pregnant adolescents, oxygen saturation below 95% was an independent risk factor for ICU admission, which agrees with the finding of another Brazilian study (14) which assessed pregnant women with progression to…”

“…In our study, just under half of pregnant adolescents with COVID-19 had some comorbidity, and this condition doubled the risk of needing an ICU admission. Asthma and heart disease were the most frequent, and were the same comorbidities found in other national studies with pregnant women (14,17) , who also mentioned other diseases, such as diabetes, hypertension, and obesity. In Canada, a study with adult and pediatric patients diagnosed with COVID-19, with 1.1% of these pregnant women hospitalized in the ICU of 32 hospitals during the first half of 2020, identified the most common comorbidities were chronic arterial hypertension, diabetes, and chronic cardiovascular disease (18) .…”

“…Among all 282 pregnant adolescents included in this study, the median age was 17 (11)(12)(13)(14)(15)(16)(17)(18)(19) years; most of them had brown skin color (68.8%), were in the third trimester of pregnancy (64.6%), and lived in urban or peri-urban areas (83.7%). Also, 37.7% lived in the Northeast region and 24.1% had completed the late years of elementary school; however, the education variable was absent in 45.0% of the cases (Table 1).…”

“…A study conducted in Brazil in 2020 assessed pregnant women regardless of age, who needed to be hospitalized due to SARS by COVID-19 and, therefore, with some severity; it found that most women lived in the Southeast region of the country, and the authors associate this finding with the fact that the first cases of the disease were reported in this region, specifically in the states of São Paulo and Rio de Janeiro (14) .…”

“…The same findings were observed in a study conducted in Iran (23) , in which 62.5% of hospitalized women were in the third trimester of pregnancy. Brazilian studies often identified the occurrence of COVID-19 in the third trimester of pregnancy, with this rate ranging from 45.8% to 66.7% of pregnant women (14,17) . Of the signs and symptoms observed in national and international studies (14,17,(24)(25) , pregnant adolescents had a higher frequency of fever and cough.…”
