Analysis of Male Sex as a Risk Factor in Older Adults With Coronavirus Disease 2019: A Retrospective Cohort Study From the New York City Metropolitan Region

摘要

Background Advancing age and male sex have been identified as risk factors for poor outcomes in coronavirus disease 2019 (COVID-19). However, there is a dearth of data investigating the impact of age on the risk reported with male sex. We aimed to determine the risk associated with male sex in people of different age groups, that is, in people younger or older than 65 years of age. Methods This is a retrospective cohort study that included 370 adult patients hospitalized with COVID-19 between March 12, 2020, and May 13, 2020, at a 242-bed teaching community hospital in the New York City metropolitan region. Patients were classified into younger (age65 years, n=132) and older individuals (age=65, n=238). We calculated odds ratios for poor outcomes in men compared to women separately in these two groups. Results Among older individuals, there was no difference in the odds of poor outcomes between men and women. In contrast, among younger people, men had higher odds of severe pneumonia, need for high oxygen support, acute kidney injury and acute liver injury when compared to women. Conclusions Among people older than 65 years, sex did not impact disease severity and outcomes in COVID-19. Thus, older women were equally likely to have severe COVID-19 when compared to age-matched men. In contrast, among younger middle-aged adults (29-64 years), men had higher odds of end-organ damage from COVID-19 compared to women. Based on these observations, age is a more important driver of poor outcomes in COVID-19 than sex. Public health policies need to create awareness for the increased risk of older individuals to COVID-19, regardless of sex.
