In the meantime, the lifestyle of nurses is of two-fold importance regarding their role in providing a wide range of services.<br> <strong>Objectives: </strong>The present study aimed to determine and compare the lifestyle of nurses with and without COVID-19 working in hospitals affiliated with Tehran University of Medical Sciences, Tehran, Iran.<br> <strong>Methods:</strong> This comparative study was performed on 500 nurses working in hospitals affiliated with Tehran University of Medical Sciences in 2021. The study population included 500 nurses with (n = 250) and without (n = 250) COVID-19 nurses. The used research methods complied with the STROBE checklist. The data were collected using a demographic information questionnaire and a cross-culturally adapted nurses&rsquo; lifestyle questionnaire. Data analysis was performed using SPSS software (version 25) and descriptive and inferential statistical tests. A P-value less than 0.05 was considered the significance level.<br> <strong>Results:</strong> The mean age values of participants with and without COVID-19 were 33.9 &plusmn; 8.35 and 35.7 &plusmn; 7.02 years, respectively. The statistical t-test showed that the overall lifestyle score was significantly higher in nurses with COVID-19 (4.06 &plusmn; 0.39) than in nurses without COVID-19 (3.90 &plusmn; 0.43) (P = 0.010). The overall score of lifestyle subscales in the COVID-19 group was higher than the nonCOVID-19 group. In this regard, the highest subscale score was related to the competence dimension in both COVID-19 (4.69 &plusmn; 0.300) and nonCOVID-19 (4.57 &plusmn; 0.418) groups (P = 0.001). <strong>Conclusions: </strong>The lifestyle of COVID-19 nurses is better than nonCOVID-19 nurses. Accordingly, planning is necessary to improve the lifestyle of nurses during the COVID-19 pandemic, especially nurses without COVID-19.</span></span></div> Coronavirus,Pandemic,COVID-19,Nurse,Lifestyle 0 0 http://mcj.bums.ac.ir/browse.php?a_code=A-10-1-210&slc_lang=en&sid=1 Afzal Shamsi 10031947532846005301 10031947532846005301 No Anesthetics Group, School of Allied Medicine, Tehran University of Medical Sciences, Tehran, Iran Musab Ghaderi 10031947532846005302 10031947532846005302 No Anesthetics Group, School of Allied Medicine, Tehran University of Medical Sciences, Tehran, Iran Mansureh Jaladati mansureh.jaladati@gmail.com 10031947532846005303 10031947532846005303 Yes Baharllo Hospital, Tehran University of Medical Sciences, Tehran, Iran
