Association between chronic health conditions and severe acute respiratory syndrome in pregnant women: an exploratory study.

Objective: To analyze the association between chronic health conditions and severe acute respiratory syndrome in pregnant women.

Method: Retrospective, exploratory study conducted with 1,152 pregnant women from all 27 states of Brazil who sought hospital treatment and were diagnosed with severe acute respiratory syndrome between 2020 and 2022. Public data from the Influenza Epidemiological Surveillance Information System (SIVEP-Gripe) of the Brazilian Ministry of Health were used. Nonparametric tests were performed in data interpretation.

Results: The mortality rate of pregnant women due to severe acute respiratory syndrome in Brazil was 7%. Severe acute respiratory syndrome was statistically associated with the previous presence of diabetes (p = 0.023), neurological disease (p = 0.001), and drug use (p = 0.001). The epidemiological investigation of respiratory syndrome cases took longer in Black pregnant women (p = 0.012), unvaccinated women (p < 0.001) and women living in the north and south of the country (p = 0.011).

Conclusion: Severe acute respiratory syndrome was more common in pregnant women with diabetes, neurological disease and drug users. However, these conditions did not lead to an increase in the number of deaths.
