Population Vulnerability to severe COVID-19 According to the Data from the National Health Survey
Keywords:
coronavirus, SARS-CoV-2, risk factors, Cuba.Abstract
Introduction: New SARS-CoV-2 strains recently detected cause an increase in morbidity and mortality not only in the elderly. Identifying the vulnerable population is a challenge.
Objective: To estimate the prevalence of adults vulnerable to severe COVID-19 and its associated sociodemographic factors.
Methods: An observational cross-sectional analytic study using data from the 2018-2020 National Health Survey. It included 13 684 individuals aged 19 years and over. The structured questionnaire included information on the sociodemographic variables, personal and family pathological antecedents, and records of blood pressure and biochemistry tests, among others. Vulnerability to severe COVID-19 was developed based on the proposal from the CDC Atlanta, USA and it was the dependable variable.
Results: The prevalence of adults vulnerable to severe COVID-19 in the country was 68.3%. At higher risk are the elderly (86.5%), non-white individuals, and those who perceived themselves as having poor living conditions. For the elderly, being male was a protective factor, while living in the western region of the country was a risk factor. High blood pressure (39.4%), smoking (22.2%), obesity (16.6%) and chronic respiratory diseases (10.6%) were the most frequent health problems.
Conclusions: Vulnerability to severe COVID-19 in the Cuban adult population is high; consequently, it is considered a serious health problem. Non-modifiable factors are positively associated with vulnerability: being an older adult, female, non-white skin color, and suffering from hypertension; while “poor” living conditions is the only modifiable factor.
