“…It is possible that older adults interested in lifestyle behaviors and/or mental wellbeing during COVID-19 lockdowns could be more prone to participate and to perceive differences between pre- and during COVID-19 lockdowns. Thirdly, PA levels measurements were based on subjective descriptions rather than objective assessment, which could contribute to an overestimation of the self-reported PA levels [ 94 ]. Though, Tran et al [ 95 ] showed that IPAQ-SF is an acceptable tool to assess PA in older adults.…”

Background. The COVID-19 lockdown could engender disruption to lifestyle behaviors, thus impairing mental wellbeing in the general population. This study investigated whether sociodemographic variables, changes in physical activity, and sleep quality from pre- to during lockdown were predictors of change in mental wellbeing in quarantined older adults. Methods. A 12-week international online survey was launched in 14 languages on 6 April 2020. Forty-one research institutions from Europe, Western-Asia, North-Africa, and the Americas, promoted the survey. The survey was presented in a differential format with questions related to responses “pre” and “during” the lockdown period. Participants responded to the Short Warwick–Edinburgh Mental Wellbeing Scale, the Pittsburgh Sleep Quality Index (PSQI) questionnaire, and the short form of the International Physical Activity Questionnaire. Results. Replies from older adults (aged >55 years, n = 517), mainly from Europe (50.1%), Western-Asia (6.8%), America (30%), and North-Africa (9.3%) were analyzed. The COVID-19 lockdown led to significantly decreased mental wellbeing, sleep quality, and total physical activity energy expenditure levels (all p < 0.001). Regression analysis showed that the change in total PSQI score and total physical activity energy expenditure (F(2, 514) = 66.41 p < 0.001) were significant predictors of the decrease in mental wellbeing from pre- to during lockdown (p < 0.001, R2: 0.20). Conclusion. COVID-19 lockdown deleteriously affected physical activity and sleep patterns. Furthermore, change in the total PSQI score and total physical activity energy expenditure were significant predictors for the decrease in mental wellbeing.

“…Some studies have reported shorter nocturnal TIB independent of insomnia, no change in TIB, or improved sleep quality [ 15 – 21 ]. Studies accessing large scale databases from wearable [ 22 ] or smartphone crowdsourcing technology [ 23 , 24 ] report that at the population level, sleep was ~20 minutes later and ~20 minutes longer during social-distancing. Only one study to our knowledge collected TIB data prospectively from young adult university students, using a daily log to record bedtime and wakeup time for a week prior to and again during public ’Stay-At-Home’ orders [ 25 ].…”

Impact of COVID-19 social-distancing on sleep timing and duration during a university semester

Social-distancing directives to contain community transmission of the COVID-19 virus can be expected to affect sleep timing, duration or quality. Remote work or school may increase time available for sleep, with benefits for immune function and mental health, particularly in those individuals who obtain less sleep than age-adjusted recommendations. Young adults are thought to regularly carry significant sleep debt related in part to misalignment between endogenous circadian clock time and social time. We examined the impact of social-distancing measures on sleep in young adults by comparing sleep self-studies submitted by students enrolled in a university course during the 2020 summer session (entirely remote instruction, N = 80) with self-studies submitted by students enrolled in the same course during previous summer semesters (on-campus instruction, N = 452; cross-sectional study design). Self-studies included 2–8 week sleep diaries, two chronotype questionnaires, written reports, and sleep tracker (Fitbit) data from a subsample. Students in the 2020 remote instruction semester slept later, less efficiently, less at night and more in the day, but did not sleep more overall despite online, asynchronous classes and ~44% fewer work days compared to students in previous summers. Subjectively, the net impact on sleep was judged as positive or negative in equal numbers of students, with students identifying as evening types significantly more likely to report a positive impact, and morning types a negative impact. Several features of the data suggest that the average amount of sleep reported by students in this summer course, historically and during the 2020 remote school semester, represents a homeostatic balance, rather than a chronic deficit. Regardless of the interpretation, the results provide additional evidence that social-distancing measures affect sleep in heterogeneous ways.

The COVID-19 pandemic imposed massive changes to daily lives worldwide. While lockdowns arrived abruptly, the continuation of social-distancing measures like working from home could have longer-term influences. We longitudinally tracked lifestyle behaviors (sleep/physical activity/phone use) and mental wellbeing through lockdown and reopening in Singapore. Earlier sleep and increased physical activity benefited from offices reopening for in-person work. However, this was offset by higher stress and poorer mood. Changes were proportional to the degree of hybrid work adoption. Counter to expectation, smartphone usage did not decrease after reopening, and usage around bedtime increased marginally. Cluster analysis showed that while heavier bedtime smartphone use was associated with later sleep initiation and lower physical activity, intermediate bedtime usage was associated with more favorable wellbeing indicators. As hybrid work arrangements and expanded e-device use will likely persist during the pandemic and its aftermath, our findings could inform strategies on adapting to new societal norms.
