“…58,59 Preliminary and largely self-reported evidence from around the world indicates that during the pandemic, children were more sedentary, engaged in more screen time 39 and less physical activity, 13,40,41 ate more unhealthy and fewer healthy foods, 13,42 and experienced later and more variable sleep schedules. 43,44 Engagement in similar behaviors is likely the behavioral mechanism responsible for the accelerated BMI gain in the current study.…”

“…Studies conducted to examine adolescents’ sleep during the COVID-19 pandemic have found that, among typically developing adolescents, sleep schedules were delayed [ 32 – 34 ], sleep duration was extended, and daytime sleepiness decreased [ 34 – 36 ]. Results regarding the prevalence or severity of sleep disruptions have been inconsistent, with some studies reporting that disruptions worsened [ 32 , 37 – 39 ] while others found that they improved [ 40 ].…”

Objective To prospectively document changes in adolescents’ sleep before versus during the COVID-19 pandemic, and to examine their impact on adolescents’ perceived stress. Methods Sixty-two typically developing adolescents participated in the study before (Time 1: January 15 to March 13, 2020) and during (Time 2: May 15 to June 30, 2020) the COVID-19 pandemic in Canada. At Time 1, each participant’s sleep pattern was assessed in the home environment using actigraphy and sleep logs for seven consecutive nights. Adolescents completed a battery of questionnaires in which they reported on their sleep schedule, duration, and quality, as well as their activities at bedtime, their daytime sleepiness, and their social/emotional behavior. The participants’ parents provided demographic information. At Time 2, each participant completed a sleep log, the same battery of questionnaires regarding sleep, and the Perceived Stress Scale. Results (1) Adolescents’ reported sleep was of longer duration and on a delayed schedule during the COVID-19 pandemic compared to pre-pandemic. (2) A larger proportion of adolescents reported meeting or exceeding the recommended amount of sleep during the COVID-19 pandemic compared to pre-pandemic sleep. (3) “Social jet lag” disappeared during the COVID-19 pandemic. (4) A shorter reported sleep duration and higher level of arousal at bedtime at Time 1 were significant predictors of adolescents’ perceived stress at Time 2—during the COVID-19 pandemic. (5) A higher levels of arousal at bedtime and lower reported sleep quality at Time 2 were concurrently associated with higher levels of perceived stress among adolescents, even when we controlled for the levels of pre-pandemic emotional or behavioral issues, sleep duration, or sleep quality. Conclusion Sleep duration and cognitive-emotional arousal, which are both modifiable behaviors, were associated with adolescents’ perceived stress during the COVID-19 pandemic. These behaviors could be useful targets for preventive interventions aiming to reduce adolescents’ stress in the face of stressogenic situations, such as the COVID-19 pandemic.

“…However, highly consistent lockdown-related lifestyle changes have been documented across different populations and countries 5,[53][54][55] . Prior studies in Singapore confirm these lockdown effects in wider samples of working adults and children 12,56 . As the pandemic situation has naturally impeded data collection from human subjects, much research has relied on survey data 57 .…”

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.
