Home working and physical activity during SARS-CoV-2 pandemic: A longitudinal cohort study

Background: Due to the SARS-CoV-2 pandemic, human lifestyles and occupational settings have changed in the workplace. This survey explores associations of home working employment and related physical activity (PA–MET min/week). Methods: A longitudinal cohort study was conducted between March 2020 and March 2021. A standardized method for assessing PA and sedentary time, the Italian version of the International Physical Activity Questionnaire-Short Form (IPAQ-SF), was used through the Microsoft Forms® platform for self-administering the questionnaire. Baseline data were collected, and four follow-ups were performed; a full calendar year was observed. Results: In total, 310 home workers were recruited in this investigation. The average body mass index (BMI-kg/m2) was 21.4 ± 4.2 at baseline. The value increased at the first follow-up and fluctuated in the other recalls. The t-test of MET values of the four activities (Total PA, Vigorousintensity activity, Moderate-intensity activity, Walking) show similar results; the total PA, at baseline 275.7 ± 138.6, decreased statistically significantly at the first (198.5 ± 84.6), third (174.9 ± 98.4), and fourth (188.7 ± 78.5) follow-ups, while it increased statistically significantly at the second follow-up (307.1 ± 106.1) compared to the baseline. Sedentary time was constant until the second follow-up, while it increased statistically significantly at the 3rd and 4th follow-up. Conclusion: workers involved reduced and reorganized their PA during this pandemic year. Each business company should intervene to improve the PA levels of workers and reduce sedentary behavior in the workplace.
