The Relationship Between Food Security and Dietary Patterns Status with COVID-19 in Northeastern Iran: Protocol for a Case-Control Study

Abstract

AbstractBackgroundFood insecurity is defined as the limited or uncertain availability of enough food for a consistently active and healthy life. COVID-19 is a highly transmissible viral infection with high mortality due to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and, or the uncommon severe pneumonia. This study assesses the relationship between food security and dietary patterns status with COVID-19 in the North Khorasan province, Iran.MethodsThis case-control study will be conducted in the men and women aged 20-60 years improved from COVID-19 infection. The cases (n=124) and controls (n=124) were selected according to the eligibility criteria, including recently improved COVID-19 according to the positive COVID-19 PCR test. People referred to public and private laboratories or employees of public and private factories, offices, and departments of hospitals and universities (for the cases) and negative PCR tests without any clinical signs of COVID-19 infection (for the controls). The North Khorasan province was the target place. The groups are matched for age, sex, and body mass index (BMI). The assessments will include anthropometric measurements and general demographic, USDA 18-item food security (18item-FSSM), and 147-item food frequency (FFQ) questionnaires. Finally, the determination of the relationship between food security and dietary patterns status and associated socioeconomic factors with COVID-19 is done. P-value will be <0.05.DiscussionThis study would be the first assessment of the relationship between food security and dietary patterns status with COVID-19 disease. It may help planners and policymakers to manage food insecurity and unhealthy dietary patterns and later increasing the immune system and decreasing the incidence of COVID-19. Further studies are suggested.
