School nurse and COVID-19 response.

The role of the school nurse should not be understated when addressing the Covid-19 pandemic and its effects on children and families. Knowledge surrounding this virus is rapidly changing and quick adaptation within the school system is required. In addition to the provision of direct care and education to students, school nurse responsibilities include the development and implementation of new policies; consideration of social and emotional well-being; and effective communication with students, families, teachers, administrators, and community stakeholders. This article addresses current evidence related to the coronavirus disease 2019 (COVID-19) pandemic and the evolving role of the school nurse. A case study incorporates tips and suggestions for school nurses who will deliver professional care during this COVID-19 crisis.

COVID-19 and health in children and adolescents in the US: A narrative systematic review.

In the United States, the Coronavirus Disease 2019 (COVID-19) pandemic necessitated nationwide closures of kindergarten through twelfth grade (K-12) schools. Stay-at-home orders and social distancing mandates were also implemented to mitigate the spread of COVID-19. The purpose of this systematic review was to synthesize the existing literature on how COVID-19 impacted K-12 students' eating patterns, physical activity, and sleep in the United States. Utilizing the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a literature search was conducted between October and December 2021. Inclusion criteria were studies focused on COVID-19 and eating patterns, physical activity, and sleep in students enrolled in K-12 schools since March 2020. International studies were excluded. Mixed findings were observed for eating patterns whereby the consumption of unhealthful savory and sweet items and healthful snacks (e.g., fruit and vegetables) increased. Reductions in physical activity and disrupted sleep routines were also observed. Heterogeneity in methodological procedures may limit the generalizability of these findings. In the United States, preliminary data suggest that select health-promoting behaviors were negatively impacted by the COVID-19 pandemic. Given that prolonged unhealthful eating patterns, physical inactivity, and poor sleep contribute to chronic disease risk, initiatives that increase health-promoting behaviors are warranted.
