Abstract
Objective: To estimate the prevalence of hospitalizations due to COVID-19 and to investigate associated factors in adult patients in the city of Barbacena, Minas Gerais, Brazil. Method: This cross-sectional study included a sample of 248 community participants (≥18 years old) with post-COVID-19 complaints treated at an outpatient clinic of the Unified Health System. Data were collected between September 2021 and January 2022. The dependent variable was hospitalization due to COVID-19 (no/ yes). The independent variables were operationalized as: age group (18-59/≥60 years), sex (female/male), race (white/other), education (higher/secondary/elementary education+illiterate), marital status (no/with partner), physical activity (active/ sedentary), comorbidities (no/yes), systemic arterial hypertension (no/yes), diabetes mellitus (no/yes), use of medication as a treatment for COVID-19 (no/yes), and doses of COVID-19 vaccine (none or one/≥two or three). The prevalence of hospitalization was presented as a percentage. The association between the dependent and independent variables was assessed using binary logistic regression and expressed as odds ratio (OR). Result: The prevalence of hospitalizations due to COVID-19 was 41.5% (36.0% in women and 50.0% in men). Multivariate association analysis showed that age ≥60 years (OR=2.58 [1.41-4.73]), male sex (OR=1.98 [1.10-3.55]), physical inactivity (OR=2.24 [1.38-4.40]), presence of comorbidities (OR=3.15 [1.61-6.17]), and use of medication as a treatment for COVID-19 (OR=3.68 [1.78-7.59]) remained significantly and positively associated with greater odds of hospitalization. Conclusion: Four of 10 patients were hospitalized due to COVID-19. The burden of hospitalization was especially high among older patients, males, sedentary individuals, those with comorbidities, and those who used medication to treat COVID-19.
