Associations of Muscle-Strengthening Activity and Cognitive Function in Community-Dwelling Middle-Aged and Older Adults
Objective To determine the associations between muscle-strengthening activity (MSA) and cognitive function among middle-aged and older adults. Methods This cross-sectional study included 2973 participants aged ≥55 in the Cooper Center Longitudinal Study. Participants self-reported leisure-time physical activity. Cognitive function was assessed using the Montreal Cognitive Assessment (MoCA). The associations of reported MSA frequency (0–1 vs. ≥2 s…
Sars-CoV-2 Serostatus and Covid-19 Illness Characteristics by Variant Time Period in Non-Hospitalized Children and Adolescents
Results show an increase in symptomatic COVID-19 infection among non-hospitalized children with each progressive variant over the past two years. Findings here support the public health guidance that eligible children should remain up to date with COVID-19 vaccinations
Effects of Large-Scale Municipal Safe Routes to School Infrastructure on Student Active Travel and Physical Activity
Past evaluations of Safe Routes to School (SRTS) programs have been relatively small in scope and have lacked objective measurements of physical activity. A 2016 Mobility Bond in Austin, Texas, USA, allocated USD 27.5 million for infrastructure changes to facilitate active commuting to schools (ACS). The Safe TRavel Environment Evaluation in Texas Schools (STREETS) study aims to determine the health effects of these infrastructure changes. The pu…
Results of Covid-19 Surveillance in a Large United States Pediatric Healthcare System over One Year
Children were cumulatively impacted by the COVID-19 pandemic through the three US waves with more than a third hospitalized in Wave 3. Children with underlying health conditions were particularly at risk for severe illness and should be monitored for any long-term impacts
School Parks as a Community Health Resource
Parks are settings for physical activity that can support the physical and mental health of children during the COVID-19 pandemic. We determined the impact of the pandemic on the use of joint-use parks outside of school hours by children in Austin, TX, United States. In autumn of 2019 and autumn of 2020 (i.e., before and during the COVID-19 pandemic), we used an adapted version of the System for Observing Play and Recreation in Communities to obs…
Physical Activity and Healthy Eating Programming in Schools to Support Student’s Health-Related Fitness
Centers for Disease Control (CDC) guidelines recommend schools use a coordinated health approach to support healthy eating and physical activity. This study examines whether the number of healthy eating and physical activity programs and activities used by schools and their perceived success relate to students' health-related fitness. This observational study used data from the Healthy Zone Schools Program. Data (collected in 2017-2019) were inte…
School-Level Economic Disparities in Police-Reported Crimes and Active Commuting to School
Perceived safety remains one of the main barriers for children to participate in active commuting to school (ACS). This ecological study examined the associations between the number of police-reported crimes in school neighborhoods and ACS. The percentage of active travel trips was assessed from a teacher tally survey collected from students across 63 elementary schools that were primarily classified as high-poverty ( n = 27). Geographic Informat…

Background The purpose of this study was to: 1) examine the maintenance of Physical Education and physical activity during the distance learning time, 2) determine the resources educators are utilizing to deliver PE curricula, and 3) understand the challenges experienced by educators during distance learning. Methods A survey was sent to a cohort of school-based fitness assessment software users. Respondents were largely school-based individuals …
Effects of trees, gardens, and nature trails on heat index and child health
Background Latinx children in the United States are at high risk for nature-deficit disorder, heat-related illness, and physical inactivity. We developed the Green Schoolyards Project to investigate how green features—trees, gardens, and nature trails—in school parks impact heat index (i.e., air temperature and relative humidity) within parks, and physical activity levels and socioemotional well-being of these children. Herein, we present novel m…
Physical Activity Engagement outside of College Physical Education
Objective: In this study, we examined physical activity (PA) engagement outside of college physical education (PE) classes using the Transtheoretical Model (TTM). Methods: Overall, 414 university students enrolled in PE classes voluntarily participated in this study. Participants were asked to complete a survey packet to measure 4 core constructs of TTM and their PA level performed outside of PE classes. Among the participants, 150 randomly selec…
Associations between gender, school socioeconomic status, and cardiorespiratory fitness among elementary and middle school students
Results suggest girls in Healthy Zone Schools have lower odds to meet aerobic capacity fitness standards than boys. Additionally, boys and girls in schools serving a greater percentage of economically disadvantaged students have lower odds to meet aerobic capacity fitness standards. Last, girls have even lower odds of meeting HFZ standard when attending a school serving a greater percentage of economically disadvantaged students. Thus, schools ne…
Factors Associated with Use of Recreational Facilities and Physical Activity Among Low-Income Latino Adults

Meeting Physical Activity Guidelines is Associated with Lower Allostatic Load and Inflammation in Mexican Americans
The pandemic of physical inactivity
Physical inactivity is the fourth leading cause of death worldwide. We summarise present global efforts to counteract this problem and point the way forward to address the pandemic of physical inactivity. Although evidence for the benefits of physical activity for health has been available since the 1950s, promotion to improve the health of populations has lagged in relation to the available evidence and has only recently developed an identifiabl…
