The aim of this research is to collect dietary intake, physical activity, mood and stress data during and after the Illinois shelter-in-place and social distancing orders for the COVID-19 pandemic. The study's intent is to capture data during this unprecedented time to understand the non-infection consequences of social distancing and shelter-in-place, including duration of affect after orders are lifted.

The proposed study is an observational study. The study will include our previous subjects, those who are following the shelter- in- place order due to the COVID-19 pandemic. Demographic data of individuals participating in the study will be recorded. During this 12-month protocol, participants will be contacted through email to complete online questionnaires on weekly basis for 8 weeks, and then once every 4 weeks until the end of the study. Subjects will record their one-day food intake, physical activity, sleep, and stress and anxiety level, which takes ~1 hour to complete.

Subjects will be recruited through our CNRC databases of individuals who come to our clinic in the past 1 year, online advertisement, and word of mouth. A phone and/or email will be administered to ensure their eligibility using our standard tools and protocols. People who are willing and able to participate and meet the basic screening eligibility will be contacted through email for informed consent and the continuing of the study.
