Relationship between COVID-19 Vaccination and Demographic Characteristics in Patients with COVID-19

COVID-19 is a rapidly spreading acute respiratory syndrome worldwide. COVID-19 vaccination has been widely used as a means to control the disease. This study aimed to investigate the relationship between demographic characteristics and COVID-19 vaccination in patients with COVID-19.

This descriptive-analytical study was conducted on 1124 patients with a definitive diagnosis of COVID-19 in Minoodasht, Iran, in August 2021. The instruments used in this study included a demographic data questionnaire and a checklist assessing patient characteristics.

The majority of COVID-19 patients were men (51.8%), aged between 35 to 45 years (26%), and married (76.5%). COVID-19 vaccination was administered to 26.6% of the patients. Patients who received vaccination (27.1%) used masks less than unvaccinated patients (72.9%) (P<0.05). Of the patients with COVID-19, 8.2% were hospitalized. The mean duration of hospitalization for vaccinated patients (7.8±6.4 days) was lower than that for unvaccinated patients (8.3±5.9 days); however, this difference was not significant. Age, education, underlying disease, and mask usage were associated with COVID-19 vaccination (P<0.05). With an increase in underlying disease and age, vaccination rates increased, while vaccination rates decreased with the use of masks and lower education.

Attention to demographic factors and certain characteristics of individuals is necessary to improve COVID-19 vaccination rates. Previous COVID-19 vaccination does not decrease the number of hospitalization days in patients with COVID-19.
