Project COPE: An Investigation of Daily Experiences of Stress, Physical Activity, and Sleep During the COVID-19 Pandemic

Description
The health benefits of sufficient moderate-to-vigorous physical activity (MVPA) and sleep arewell-supported, with established links to decreased cancer risk, cardiometabolic health, all-cause mortality, and psychiatric symptomatology—including stress-related phenomena—for those who engage in 150 min MVPA/week and get at least 7 hours sleep/night.

The health benefits of sufficient moderate-to-vigorous physical activity (MVPA) and sleep arewell-supported, with established links to decreased cancer risk, cardiometabolic health, all-cause mortality, and psychiatric symptomatology—including stress-related phenomena—for those who engage in 150 min MVPA/week and get at least 7 hours sleep/night. The latter outcome has rapidly become a major public health concern as our nation grapples with the impact of prolonged COVID-19 pandemic stress, which has triggered an onslaught of depression, anxiety, and PTSD throughout the population. Thus, while strategies to decrease stress are desperately needed, many Americans fall short of the very MVPA and sleep recommendations that have been shown to increase their capacity to cope. The purpose of the present study was to explore time-varying associations of MVPA and sleep with momentary perceived stress in adults forced to work from home due to the COVID-19 pandemic. Thirty remote-working adults (86.7% women; mean age 37.5 years, SD = 10.4 years) wore GENEActiv accelerometers on the wrist to capture MVPA and sleep data, and answered four Ecological Momentary Assessments (EMAs) per day regarding perceived stress, for fourteen days straight. Between- and within-person variations in MVPA, sleep quality rating (SQR), total sleep time (TST), and sleep efficiency (SE) were analyzed via multilevel models to determine whether certain changes in these parameters might lead to decreased perceived momentary stress. Between-person models revealed a significant negative effect of SQR on perceived stress levels the next day, beta= -.651, SE= .303, P= .04. Mean MVPA, TST, and SE were not significant inter-individual predictors of momentary stress. However, within persons, higher than normal MVPA (beta= -.005, SE= .002, P= .015), SQR (beta= -.277, SE= .071, P <.001), TST (beta= -.001, SE= .000, P = .004), and SE (beta= -.524, SE= .242, P = .031) were all associated with significant decreases in momentary stress, with individuals experiencing incremental benefits with each additional minute of MVPA and TST. In conclusion, daily fluctuations in MVPA and sleep habits correlate more strongly with momentary stress than do typical levels of these behaviors; this presents an attainable strategy for individuals to enhance their capacity to cope.
