Changes in Physical Activity, Heart Rate, and Sleep Measured by Activity Trackers During the COVID-19 Pandemic Across 34 Countries: Retrospective Analysis

A systematic review highlighted the beneficial effects of PA on physical and mental health during the first year of the COVID-19 pandemic [9]. The review found that engaging in regular PA helped to mitigate the negative impact of pandemic-induced stress [9]. In addition, inactive individuals were reported to have lower well-being scores and higher levels of depression and anxiety than moderately active and active individuals.

COVID-19–Related Racism and Mental Health Among Asian Americans: Integrative Review

COVID-19–Related Racism and Mental Health Among Asian Americans: Integrative Review

COVID-19 is related to an earlier viral strain that caused a smaller-scale pandemic in November 2002 with clinical presentation of severe acute respiratory syndrome. Both phenomena originated in China, fueling the spread of misinformation and anti-Asian sentiments. Studies indicate that anti-Asian sentiments (racist sentiments, including microaggression and unconscious biases) increased significantly during the COVID-19 pandemic [18,20,21,24-27].

Accessibility of eHealth Before and During the COVID-19 Pandemic Among People With and People Without Impairment: Repeated Cross-Sectional Survey

Adoption of e Health accelerated during the COVID-19 pandemic [1]. Before the pandemic, we identified a disability digital divide in e Health, that is, people with impairment reported less use and more difficulty in the use of e Health, particularly with some types of impairment (language impairments and intellectual impairments) [2]. Sustainable development [3], legislation, and human rights principles [4] demand accessible e Health for all.

COVID-19 Public Health Communication on X (Formerly Twitter): Cross-Sectional Study of Message Type, Sentiment, and Source

During the COVID-19 pandemic [9], social media successfully informed and increased public awareness about this new phenomenon [10]. However, there were considerable differences in the preferred social media platforms, message formats and source sender types [11]. An important concern during the COVID-19 pandemic was the spread of misinformation on social media [12].

Investigating the Magnitude and Persistence of COVID-19–Related Impacts on Affect and GPS-Derived Daily Mobility Patterns in Adolescence and Emerging Adulthood: Insights From a Smartphone-Based Intensive Longitudinal Study of Colorado-Based Youths From June 2016 to April 2022

Investigating the Magnitude and Persistence of COVID-19–Related Impacts on Affect and GPS-Derived Daily Mobility Patterns in Adolescence and Emerging Adulthood: Insights From a Smartphone-Based Intensive Longitudinal Study of Colorado-Based Youths From June 2016 to April 2022

Several studies found that mobility changes were moderated by factors like local pandemic severity and sociodemographic characteristics like age, race or ethnicity, and income levels [28,29,32,34-36]. Pandemic-related mobility disruptions are widely studied among adults, though little research has investigated effects on youth mobility.

The Measurement of Vital Signs in Pediatric Patients by Lifelight Software in Comparison to the Standard of Care: Protocol for the VISION-Junior Observational Study

The COVID-19 pandemic has also highlighted the need for methods suitable for the remote or contactless measurement of VS that can be operated by people without specific medical training. The growing use of telemedicine since the pandemic also points to the need for easy but accurate measurement of VS.

Experiences of Public Health Professionals Regarding Crisis Communication During the COVID-19 Pandemic: Systematic Review of Qualitative Studies

Experiences of Public Health Professionals Regarding Crisis Communication During the COVID-19 Pandemic: Systematic Review of Qualitative Studies

The COVID-19 pandemic claimed millions of lives. It resulted in a public health crisis and caused economic and social turmoil worldwide. No country, irrespective of region or wealth, was spared the devastating effects of the COVID-19 pandemic. Given that there were no available drugs or vaccines early in the pandemic, communication was an important means of containing the crisis. Even after vaccines were developed, communication to increase trust in the vaccines was central to ending the crisis.

COVID-19 Testing Equity in New York City During the First 2 Years of the Pandemic: Demographic Analysis of Free Testing Data

COVID-19 Testing Equity in New York City During the First 2 Years of the Pandemic: Demographic Analysis of Free Testing Data

Early in the pandemic, within the United States and especially within NYC, testing availability was extremely limited. In fact, there were no positive test results recorded in NYC until the beginning of March 2020 [2]. Over the ensuing 3 years, over 45,000 deaths and over 3.2 million infections were documented in NYC—a wave of mortality that contributed to a decline of 4.6 years in life expectancy from 2019 to 2020 alone [3].

Nationwide Trends in Screen Time and Associated Risk Factors by Family Structures Among Adolescents, 2008-2022: Nationwide Cross-Sectional Study

With the onset of the COVID-19 pandemic, there is growing global attention to screen time among adolescents. In South Korea, concerns about excessive screen time among adolescents predate the pandemic. The “Shutdown Law,” implemented in 2011, restricted web-based gaming for those younger than 16 years old during late-night hours to prevent gaming addiction but was abolished in 2021 [13].
