This study conducted a web-based survey to identify factors associated with depression
among college students in Hokkaido during the COVID-19 pandemic. Compared with
students in the depression group, those without depression were more likely to engage in
regular exercise and part-time jobs and had higher FFS, WHO-5, and FCV-19S scores.
Logistic regression showed that WHO-5, FCV-19S, and participation in part-time jobs
remained significantly associated with depression after adjustment. Among students who
had experienced more than two years of the pandemic, part-time employment may have
reduced social isolation and lowered the risk of depression.
