Lifestyle and mental health disruptions during COVID-19

Abstract: Using a longitudinal dataset linking biometric and survey data from several cohorts of young adults before and during the COVID-19 pandemic (N=682), we document large disruptions to physical activity, sleep, time use, and mental health. At the onset of the pandemic, average steps decline from 10,000 to 4,600 steps per day, sleep increases by 25 to 30 min per night, time spent socializing declines by over half to less than 30 min, and screen time more than doubles to over 5 h per day. Over the course of the pan… Show more

“…This vulnerable group was not solely defined by the usual risk factors of poor health. These findings closely resemble previous findings from the UK, where one out of four individuals reported depressive symptoms and one out of five individuals suffered from anxiety (O’Connor et al ., 2021). Using the same data as in our study and group-based latent growth mixture models on depressive symptoms, an outcome closely related to our measure of psychological distress, Iob et al .…”

“…Replicated in an independent test data set, our results show that social cognitive predictors outweigh the effect of negative emotionality on COVID-19-related safety behavior in young adults. We find that the pandemic in conjunction with the mandated containment measures indeed induced negative emotional reactions in young adults, as demonstrated by others (Gao et al, 2020;Giuntella, Hyde, Saccardo, & Sadoff, 2021;Qiu et al, 2020). For example, 28.4% of the current sample's participants reached scores ≥3 in the PHQ-2, which has been suggested to indicate the presence of a depressive disorder (Löwe et al, 2005).…”

“…Increased physical activity, and earlier and shorter sleep upon reopening after lockdown, reflect a partial reversal of the robust lockdown-related changes in lifestyle as reported in a rapidly growing literature 4,5,9,10,12,18,28,38,39 . Interestingly, smartphone usage was not significantly reduced upon reopening and there was also a slight increase in experienced stress, and a worsening of evening mood.…”

“…Furthermore, with face-to-face communication severely limited, people have turned to digital technology to stay connected for social interaction, work/education, and entertainment [14][15][16][17] . Many of these acute changes were associated with a negative impact on health and mental wellbeing [18][19][20][21][22] .…”
