Factors associated with decreased physical activity levels among community-dwelling residents during the coronavirus disease 2019 pandemic: a long-term observational study

抄録

[Purpose] The purpose of this study was to determine the factors associated with decreased physical activity levels among community residents over a long-term observation period during the coronavirus disease 2019 (COVID-19) pandemic. [Participants and Methods] We conducted a cross-sectional study using a self-administered questionnaire and daily steps as an indicator of physical activity levels. The study population consisted of 704 community-dwelling residents aged 40 years and older who participated in the health program from 2019 to 2020. We compared the daily steps from March–December 2019 to March–December 2020 and performed multivariate analysis to identify the factors associated with decreased daily steps. [Results] Of all participants, 447 (63.5%) returned the questionnaire and 309 (43.9%) were included in the analysis. During the COVID-19 pandemic, 133 (43.0%) respondents had decreased physical activity levels. The multivariate analysis showed that working (odds ratio, 2.08; 95% confidence interval, 1.10–3.94) was significantly associated with decreased daily steps during the COVID-19 pandemic. [Conclusion] There was a significant association between decreased physical activity levels and working during the COVID-19 pandemic. When restrictive measures such as teleworking are implemented, it may be necessary to take measures to prevent a decline in physical activity levels.
