Factors associated with COVID-19 severity among Brazilian pregnant adolescents: a population-based study.
Brenda Katheryne Duarte, Ana Beatriz Henrique Parenti, Milena Temer Jamas and 2 others
PMID 36197387WHAT IT FOUND
Pregnant adolescents with COVID-19 in Brazil who lived in the Southeast region, had oxygen saturation below 95%, or had a comorbidity were associated with needing intensive care.
Check oxygen levels and pre-existing conditions in prenatal care.
Key findings
0141 of 282 pregnant adolescents needed ICU admission, a rate of 14.5%.
02Living in the Southeast region was independently associated with ICU admission (RR=5.03, 95%CI=1.78-14.24, p=0.002).
03Oxygen saturation below 95% and any comorbidity were independently associated with ICU admission (RR=2.62, 95%CI=1.17-5.87, p=0.019; RR=2.05, 95%CI=1.01-4.16, p=0.047).

What it does not show
The study used existing case records, so some variables were missing or low quality, and cases may have been under-recorded; the final sample was 282 cases, and some confidence intervals were wide. Blank symptom and comorbidity fields were counted as absent, which could underestimate true symptom or comorbidity burden. The Southeast region finding may reflect reporting patterns, pandemic timing, and health-system differences rather than a direct cause of severe disease. The study reports association with ICU admission, not whether any treatment changed the risk.
The easy way to misread this
Do not read the Southeast region result as proof that living there causes severe disease. This is an observational study of recorded cases, and the region estimate has a wide confidence interval, so it may reflect where cases were reported and how services were organized.
