Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
The present longitudinal study aims to investigate the risk factors for getting COVID-19 in a population aged 50 to 74 years. Data were collected from Shahroud Eye Cohort Study and the electronic system of COVID-19 in Shahroud, northeast Iran. Participants were followed for about 13 months and predisposing factors for COVID-19 infection were investigated using log binomial model and by calculation of relative risks. From the beginning of the COVID-19 outbreak in Shahroud (February 20, 2020) to March 26, 2021, out of 4394 participants in the Eye Cohort Study, 271 (6.1%) were diagnosed with COVID-19 with a positive Reverse Transcription Polymerase Chain Reaction test on two nasopharyngeal and oropharyngeal swabs. Risk factors for getting COVID-19 were included male gender (Relative Risk (RR) = 1.51; 95% Confidence Intervals (CI), 1.15-1.99), BMI over 25 (RR = 1.03; 95% CI, 1.01-1.05) and diabetes (RR = 1.31; 95% CI, 1.02-1.67). Also, smoking (RR = 0.51; 95% CI, 0.28-0.93) and education (RR = 0.95; 95% CI, 0.92-0.98) had reverse associations. In conclusion men and diabetic patients and those who have BMI over 25, should be more alert to follow the health protocols related to COVID-19 and priority should be given to them considering COVID-19 vaccination.
