Objective: During the investigation of the new coronary pneumonia epidemic, this study
used a test method to compare the depressive mood of the public and orthopedic patients under the
current new coronary pneumonia epidemic, and examined the relationship between depressive mood
and physical activity. Methods: Questionnaire survey method was used, QR code and questionnaire link
were issued, and the questionnaire survey was carried out by department work group and research group
members, including sociodemographic data questionnaire, physical activity scale (PAS) and Center for
Epidemiological Research Depression Scale. Results: A total of 246 valid questionnaires were collected,
the incidence of depression was 39.84%, and the average total physical activity was 148.13. Among
them, low physical activity accounted for 47.15%, moderate physical activity accounted for 28.05, and
high physical activity accounted for 24.8%. Depression was significantly associated with high (r=-0.17,
p<0.01), moderate (r=-0.25, p<0.01), and low (r=-0.23, p<0.01) levels of physical activity. Significant
negative correlation (r=-0.64, p<0.01). In particular, moderate-intensity physical activity had a significant
negative predictive effect on depression (β=-0.25, p<0.05). Conclusion: During the COVID-19 epidemic,
depression was common among the public and orthopedic patients, which was closely related to the
occurrence of different intensity of physical activity and moderate physical activity.
