Child and family factors associated with child mental health and well-being during COVID-19.

Understanding the implications of the COVID-19 pandemic on the current generation of youth is critical for post-pandemic recovery planning. This study aimed to identify the most salient child (i.e., connectedness to caregivers, screen time, sleep, physical activity, peer relationships, and recreational activities) and family (i.e., COVID-19 financial impact, maternal depression and anxiety) factors associated with children's mental health and well-being during the COVID-19 pandemic, after controlling for pre-pandemic mental health. This study included 846 mother-child dyads (child age 9-11) from the All Our Families cohort. Mothers reported on the child's pre-pandemic mental health at age 8 (2017-2019) and during COVID-19 (May-July 2020), the family's financial impact due to COVID-19, and maternal depression and anxiety. During COVID-19 (July-August 2020), children reported on their screen time, sleep, physical activity, peer and family relationships, and recreational activities, as well as their happiness, anxiety and depression. After controlling for pre-pandemic anxiety, connectedness to caregivers (B - 0.16; 95% CI - 0.22 to - 0.09), child sleep (B - 0.11; 95% CI - 0.19 to - 0.04), and child screen time (B 0.11; 95% CI 0.04-0.17) predicted child COVID-19 anxiety symptoms. After controlling for pre-pandemic depression, connectedness to caregivers (B - 0.26; 95% CI - 0.32 to - 0.21) and screen time (B 0.09; 95% CI 0.02-0.16) predicted child COVID-19 depressive symptoms. After controlling for covariates, connectedness to caregivers (B 0.36; 95% CI 0.28-0.39) predicted child COVID-19 happiness. Fostering parent-child connections and promoting healthy device and sleep habits are critical modifiable factors that warrant attention in post-pandemic mental health recovery planning.
