PHO Rounds: Mostly Worse, Occasionally Better: The First Wave of the COVID-19 Pandemic and the Mental Health of Children and Adolescents in Ontario

Public health (or emergency) measures implemented to mitigate COVID-19 may have unintended consequences on the mental health of children and youth. This large cross-sectional cohort study examined the impact of COVID-19 emergency measures on child/adolescent mental health for children/adolescents with and without pre-existing psychiatric diagnoses. Parents of children ages 2-18 and self-reporting children/adolescents ages 10-18 indicated changes in mental health across six domains: depression, anxiety, irritability, attention, hyperactivity, and obsessions/compulsions. 67-70% of children/adolescents experienced deterioration in at least one mental health domain. 19-31% of children/adolescents experienced improvement in at least one domain. Children/adolescents with and without psychiatric diagnoses experienced deterioration, with increased rates in those with a pre-existing diagnosis. Greater stress from social isolation was associated with deterioration in all mental health domains. Enhancing social interactions for children/adolescents will be an important mitigation strategy for current and future COVID-19 waves.

By the end of this session, participants will be able to:

  1. Identify the impacts of public health measures on child and youth mental health in a global context
  2. Compare the rates of deterioration and improvement in child and youth mental health in Ontario during the first wave of the pandemic and before the pandemic 
  3. Identify the variables associated with deterioration and improvement in child and youth mental health in Ontario during the first wave of the pandemic
  4. Discuss ideas for improving child and youth mental health during subsequent waves of the pandemic
