Decrease in activity and its related factors under COVID-19 crisis in community-dwelling older people

Abstract

Aim: To prevent the transmission of the novel coronavirus and stop its spread, a state of emergency was declared from April to May 2020. People were encouraged to refrain from outings and reduce their contact with people. The purpose of this study was to examine the subjective changes in the amount of activity under COVID-19 crisis among the elderly and the factors related to this decrease in activity. Methods: This study was part of the SONIC study, an ongoing prospective cohort study targeting community dwelling older people in their 70, 80, 90s, and over 100 years old in different regions (urban and suburban) of Japan. Subjective changes in the amount of activity during the state of emergency were assessed via a mail questionnaire. Results: The percentage decrease in activity for the subjects in their 70s, 80s, and 90s were 68.1% (513/753), 65.3% (324/496), and 56.0% (164/293), respectively. By region, 69.4% in urban, while 57.7% in the suburbs. In the 70-and 80-year-old cohorts, the decrease in activity was more frequent among those in urban areas than in suburban areas. In the 90-year-old cohort, the differences between the regions were attenuated, while the economic status and walking speed were significantly associated with a decrease in activity. Conclusions: The decrease in activity varied by age group and region, suggesting that approaches to preventing the adverse health effects associated with inactivity due to the COVID-19 crisis are more important in urban areas than in suburban ones.

Factors Related to Preventive Behaviors against a Decline in Physical Fitness among Community-Dwelling Older Adults during the COVID-19 Pandemic: A Qualitative Study

“…A total of 269 participants living in Itami and Asago responded to the appropriate questionnaires of this study (response rate: 54.2%). [20]. Among them, the participants who had not been diagnosed with "major sarcopenia" in the previous survey of 2019 (n = 252) were included in the study.…”

Lower cognitive function as a risk factor for anemia among older Japanese women from the longitudinal observation in the SONIC study

“…Godai et al reported that people living in rural areas had a higher amount of activity than those living in urban areas. 28 Differences in lifestyle and behavior between urban and rural areas might have influenced the onset of anemia. However, further research is required to confirm the relationship between activity level and anemia.…”
