The results showed that prevalence of inactivity among US adults decreased 0.

Changes in Teleworking and Physical Activity Behaviors in the United States Before and After Emergence of COVID-19.

Objective: The aim of the study is to determine the prevalence of perceived decreases in three physical activity (PA) behaviors and meeting the PA guideline, by changes in telework.

Methods: US workers ( N = 2393) reported teleworking and PA behaviors before and after COVID-19 emergence. Those reporting more and less telework were compared with those reporting stable telework on prevalence of (1) decreasing behaviors and (2) meeting the aerobic guideline (≥150 min/wk of moderate-intensity PA).

Leisure-time physical activity and mortality from influenza and pneumonia: a cohort study of 577 909 US adults.

Objective: To examine the association of leisure-time physical activity with mortality from influenza and pneumonia.

Methods: A nationally representative sample of US adults (aged ≥18 years) who participated in the National Health Interview Survey from 1998 to 2018 were followed for mortality through 2019. Participants were classified as meeting both physical activity guidelines if they reported ≥150 min/week of moderate-intensity equivalent aerobic physical activity and ≥2 episodes/week of muscle-strengthening activity.

Awareness and Knowledge of the Physical Activity Guidelines for Americans, 2nd Edition.

Background: Assessing awareness and knowledge of the Physical Activity Guidelines for Americans, 2nd edition (Guidelines), released in 2018, is important for monitoring factors that contribute to increasing physical activity.

Methods: We estimated prevalence of awareness and knowledge of the adult aerobic guideline (≥150 min/wk of moderate-intensity equivalent aerobic physical activity preferably spread out over a week) among adults (n = 3471) and of the youth aerobic guideline (≥60 min/d of mostly moderate- to vigorous-intensity aerobic physical activity) among a subset of parents (n = 744) from a nationwide sample of US adults in the 2019 FallStyles survey. We estimated odds ratios using logistic regression, adjusting for demographic and other characteristics.

Association between passively collected walking and bicycling data and purposefully collected active commuting survey data-United States, 2019.

Commercially-available location-based services (LBS) data derived primarily from mobile devices may provide an alternative to surveys for monitoring physically-active transportation. Using Spearman correlation, we compared county-level metrics of walking and bicycling from StreetLight with metrics of physically-active commuting among U.S.

Traffic as a barrier to walking safely in the United States: Perceived reasons and potential mitigation strategies.

Motor vehicle traffic is commonly cited as a barrier to walking, but national level perceptions of traffic characteristics that negatively influence walking and potential traffic mitigation strategies remain unclear. The objectives of this study were to describe perceptions of (1) traffic characteristics that make walking unsafe in the United States and (2) potential mitigation strategies to address these concerns among those who report traffic as a barrier to walking. Data were from , a nationwide internet panel survey conducted in October 2019 (n = 3,284 adults).

Introduction: Obesity and physical inactivity are considered possible U.S. national security threats because of their impact on military recruitment.

Telehealth and Public Health Practice in the United States-Before, During, and After the COVID-19 Pandemic.

Telehealth is the use of electronic information and telecommunication technologies to provide care when the patient and the provider are not in the same room at the same time. Telehealth accounted for less than 1% of all Medicare Fee-for-Service outpatient visits in the United States in 2019 but grew to account for 46% of all visits in April 2020. Changes in reimbursement and licensure policies during the COVID-19 pandemic appeared to greatly facilitate this increased use.

Observation of and intention to use new places and changed spaces for physical activity during the COVID-19 pandemic - United States, June 2021.

The COVID-19 pandemic prompted built environment changes throughout the United States. We assessed the prevalence of new places and changed spaces for physical activity as observed by US adults and their intentions to use them. We used data from SummerStyles, a web-based survey of US adults conducted in June 2021 (n = 4073).

Trends in Clinical Severity of Hospitalized Patients With Coronavirus Disease 2019-Premier Hospital Dataset, April 2020-April 2021.

Background: Clinical severity of coronavirus disease 2019 (COVID-19) may vary over time; trends in clinical severity at admission during the pandemic among hospitalized patients in the United States have been incompletely described, so a historical record of severity over time is lacking.

Methods: We classified 466677 hospital admissions for COVID-19 from April 2020 to April 2021 into 4 mutually exclusive severity grades based on indicators present on admission (from most to least severe): Grade 4 included intensive care unit (ICU) admission and invasive mechanical ventilation (IMV); grade 3 included non-IMV ICU and/or noninvasive positive pressure ventilation; grade 2 included diagnosis of acute respiratory failure; and grade 1 included none of the above indicators. Trends were stratified by sex, age, race/ethnicity, and comorbid conditions.

Long-Term Symptoms Among Adults Tested for SARS-CoV-2 - United States, January 2020-April 2021.

Long-term symptoms often associated with COVID-19 (post-COVID conditions or long COVID) are an emerging public health concern that is not well understood. Prevalence of post-COVID conditions has been reported among persons who have had COVID-19 (range = 5%-80%), with differences possibly related to different study populations, case definitions, and data sources (1). Few studies of post-COVID conditions have comparisons with the general population of adults with negative test results for SARS-CoV-2, the virus that causes COVID-19, limiting ability to assess background symptom prevalence (1).

Participation in Leisure-Time Aerobic Physical Activity Among Adults, National Health Interview Survey, 1998-2018.

Background: Adults should perform ≥150 minutes per week of moderate-intensity equivalent physical activity for substantial health benefits and >300 minutes per week for additional benefits. The authors analyzed 21 years of National Health Interview Survey data to better understand trends in aerobic physical activity participation among US adults.

Methods: The authors estimated the annual prevalence (1998-2018) of self-reported leisure-time physical inactivity, insufficient activity, meeting only the minimal aerobic guideline, and meeting the high aerobic guideline overall and by selected characteristics.
