Economic Migrants and Clinical Course of SARS-CoV-2 Infection: A Follow-Up Study.

Abstract

Objective: To analyze whether social deprivation and economic migrant (EM) status influence the risk of being hospitalized with COVID-19. Methods: This was a retrospective follow-up study including all patients older than 18years attending the Daroca Health Center in Madrid, Spain, diagnosed with COVID-19 during September 2020. Data on EM status and other sociodemographic, lifestyle and comorbidities that could affect the clinical course of the infection were obtained from electronic medical records. Results: Of the 796 patients positive for COVID-19, 44 (5.53%) were hospitalized. No significant differences were observed between those who were hospitalized and those who were not in the mean of social deprivation index or socioeconomic status, but EM status was associated with the risk of being hospitalized (p = 0.028). Logistic regression models showed that years of age (OR = 1.07; 95% CI: 1.04-1.10), EM status (OR = 5.72; 95% CI: 2.56-12.63) and hypertension (OR = 2.22; 95% CI: 1.01-4.85) were the only predictors of hospitalization. Conclusion: Our data support that EM status, rather than economic deprivation, is the socioeconomic factor associated with the probability of hospital admission for COVID-19 in Madrid, Spain.
