Gender and age ratio in patients hospitalized and deceased from COVID-19. Vestsi Natsyyanal’nai akademii navuk Belarusi

The COVID-19 pandemic determines the relevance of conducting a study of the gender and age structure in hospitalized and deceased patients.The purpose of the study is to identify the patterns of the COVID-19 epidemic process in connection with the gender and age characteristics of hospitalized adults and to identify the gender and age groups wich most susceptible to hospitalization and mortality from COVID-19.

An analysis of the structure of hospitalized and deceased from COVID-19 by gender and age was carried out. Data from statistical registration forms of adults hospitalized in one of the city clinical hospitals in Moscow in 2020–2021 were used. Data processing was carried out using a set of standard statistical methods. To identify risk groups for hospitalization and mortality, statistical correction of the population composition by gender and age was used.

Data on risk groups for hospitalization and mortality among the population of Moscow at the early stage of the COVID-19 pandemic were obtained. It has been established that the risk group for hospitalization with COVID-19 is young men (average age 39.0 ± 5.0 years). They are 1.5 times more likely to be hospitalized with COVID-19 than younger women. According to COVID-19 mortality rate, the risk group is middle-aged (53.1 ± 4.3 years) and elderly (68.3 ± 4.5 years) men, for whom the mortality risk is higher than in women of the same age (3.3 and 2.2 times, respectively). Also at risk for mortality are men of age of 75–90 years, the mortality rate among them was 57 %.

The results of the study allow to identify true risk groups for hospitalization and mortality due to COVID-19, complement new knowledge into the patterns of epidemiological analysis, which is an important component of epidemiological surveillance for making management decisions to the spread prevention of SARS-CoV-2 spread prevention and planning for the provision of medical care for identified gender and age risk groups.
