The impact of COVID-19 lockdowns on physical activity amongst older adults: evidence from longitudinal data in the UK

Abstract

Background A sedentary lifestyle increases the risk of adverse health outcomes and frailty,particularly for older adults. To reduce transmission during the COVID-19 pandemic, people were instructed to stay at home, group sports were suspended, and gyms were closed, thereby limiting opportunities for physical activity. Whilst evidence suggests that physical activity levels reduced during the pandemic, it is unclear whether the proportion of older adults realising the recommended minimum level of physical activity changed throughout the various stages of lockdown. Methods We used a large sample of 3,660 older adults (aged ≥ 65) who took part in the UK Household Longitudinal Study’s annual and COVID-19 studies. We examined changes in the proportion of older adults who were realising the UK Chief Medical Officers’ physical activity recommendations for health maintenance at several time points before and after COVID-19 lockdowns were imposed. We stratified these trends by the presence of health conditions, age, neighbourhood deprivation, and pre-pandemic activity levels. Results There was a marked decline in older adults’ physical activity levels during the third national lockdown in January 2021. The proportion realising the Chief Medical Officers’ physical activity recommendations decreased from 43% in September 2020 to 33% in January 2021. This decrease in physical activity occurred regardless of health condition, age, neighbourhood deprivation, or pre-pandemic activity levels. Those doing the least activity pre-lockdown increased their activity during lockdowns and those doing the most decreased their activity levels. Conclusions Reductions in older adults’ physical activity levels during COVID-19 lockdowns have put them at risk of becoming deconditioned and developing adverse health outcomes. Resources should be allocated to promote the uptake of physical activity in older adults to reverse the effects of deconditioning.

Effects of the COVID-19 associated United Kingdom lockdown on physical activity in older adults at high risk of cardiovascular disease: a mixed methods perspective from the MedEx-UK multicenter trial

“…However, evidence from other research has suggested that deprivation was not a determinant of PA during the pandemic ( 51 ). In fact, changes in PA were more likely related to pre pandemic activity levels, with those who were most active prior to restrictions seeing the greatest reduction in PA during lockdown ( 52 ). However, we did not find this association in our study.…”

Sustaining an ageing population: the role of micronutrients in frailty and cognitive impairment

“…However, using chronological age to characterise individual mortality risk as the basis to implement a blanket policy for older adults at the population level had its problems. Such policies did not take account of the heterogeneity in the pace of ageing among older adults and failed to recognise the consequent harms of physical deconditioning, social isolation, loneliness, depression and decreased quality of life (21)(22)(23) .…”

COVID-19 Pandemic and Positive Ageing

“…This very human connectedness and resource for positive ageing has suffered from the pandemic, thus afflicting elders. Elders’ positive ageing, incorporating the maintenance of physical and social life, thus erodes with COVID-19 raging worldwide (Ekoh et al, 2022; Elliott et al, 2022). Boosting or restoring elders’ positive ageing is necessary to terminate the pandemic affliction.…”
