Sex differences in a cohort of COVID-19 Italian patients hospitalized during the first and second pandemic waves

ConclusionsThese data indicate that once patients were hospitalized, the risk of dying was similar between females and males. Therefore, future studies should aim at understanding the reasons why, for a given number of SARS-CoV-2 infections, fewer females develop the disease requiring hospitalization.HighlightsAlthough the hospitalized males were significantly more, the similar number of hospitalizations of the> 75-year-old females and males could be due to the fact that in Brescia province, elderly women are about twice as many as men.Although males spent more days in the hospital, had a longer disease duration, developed a critical illness more frequently, and were admitted and died in the ICU more than females, the total rate of deaths among patients was not significantly different between sexes.Overall, the most frequent comorbidities were cardiovascular diseases, which were preferentially seen among patients hospitalized in the second wave; it is possible that the knowledge gained in the first wave concerning the association between certain comorbidities and worse disease evolution has guided the preferential hospitalization of patients with these predominant comorbidities.
