Associations among screen time, sleep, mental health and cognitive functioning in school-aged children during the COVID-19 pandemic, November 2020 through to August 2022.

Objective: To examine children's screen time use and sleep patterns over 2 years of the pandemic and the downstream associations with children's executive functions and behavioural problems, as well as the moderating effects of parental factors.

Method: This longitudinal cohort study examined school-aged children's lifestyle and behavioural changes over 2 years of the pandemic across 6 timepoints (November 2020 to August 2022). Latent growth modeling (LGM) was used to identify changes in screen time and sleep duration and multivariate LGM was used to determine how parental stress, positive parenting, changes in children's screen time and sleep over time were associated with children's executive functions and mental health outcomes at the final time point.

Media screen time use and mental health in school aged children during the pandemic.

Background: Children's screen time activity has increased significantly during the pandemic. Extended school closures and heightened parent stress are associated with children's behavioural difficulties and time spent watching screens. The primary aim of this study was to determine which school and household factors were associated with challenging behaviours in Canadian schoolchildren during the COVID-19 pandemic.

Small-Colony Variants from Airways of Adult Cystic Fibrosis Patients as Precursors of Adaptive Antibiotic-Resistant Mutations.

Prototypic and their small-colony variants (SCVs) are predominant in cystic fibrosis (CF), but the interdependence of these phenotypes is poorly understood. We characterized isolates from adult CF patients over several years. Of 18 -positive patients (58%), 13 (72%) were positive for SCVs.

Anxiety in children and youth with autism spectrum disorder and the association with amygdala subnuclei structure.

Autism spectrum disorder (ASD) is clinically characterized by social communication difficulties as well as restricted and repetitive patterns of behavior. In addition, children with ASD are more likely to experience anxiety compared with their peers who do not have ASD. Recent studies suggest that atypical amygdala structure, a brain region involved in emotions, may be related to anxiety in children with ASD.

The disparate impact of COVID-19 pandemic on walking and biking behaviors.

This study sought to assess changes in active transportation behaviors due to the COVID-19 pandemic, in addition to identifying the disparate impacts between sociodemographic groups. A survey was conducted in November 2020, which collected responses from 1,000 Michigan residents statewide regarding walking and biking behaviors before, during, and anticipated post-pandemic. The survey found that people who walked or biked frequently for recreation before the pandemic maintained or increased their activities during the pandemic.
