Conducting 24-hour movement behaviour research with preschool children in middle-income countries: Lessons from the SUNRISE pilot study in Mexico.

Objectives: Movement behaviour research among preschoolers is nascent in low- and middle-income countries, where levels of physical activity, sleep, and sedentary behaviour in children are largely unknown. This study aimed to adapt and assess the acceptability and feasibility of the International Study of Movement Behaviours in the Early Years (SUNRISE) in Mexico, and report on challenges and solutions while implementing the protocol.

Study Design: Pilot study of the SUNRISE protocol in Mexico.

Evaluation of renal functional reserve with oral protein load or new ultrasound test.

Background: Renal functional reserve (RFR) measures the difference between the stimulated glomerular filtration rate (GFR) and the baseline GFR to detect early signs of renal functional decline. The protein load test (RFR-T) is the gold standard for RFR assessment but is a complicated procedure. Renal intraparenchymal resistance index (RRI) variation test (DRRI-T) is a non-invasive method to measure renal function reserve using ultrasound.

Comparison of Physical Activity and Sedentary Behaviour Patterns by Sex, Geographical Location, and Time of the Week in Mexican Adolescents.

Excess sedentary behaviour (SB) and insufficient physical activity have been identified as risk factors for cardiometabolic diseases in adolescents, and some factors may affect how much time they spend on these activities. This study sought to compare the SB and PA patterns as well as compliance with PA recommendations by sex, geographical location, and time of the week in Mexican adolescents. In a cross-sectional design, we objectively assessed SB and PA in 106 adolescents (15 to 18 y) through waist-worn accelerometers for one week.

The co-benefits of active travel interventions beyond physical activity: a systematic review.

Active travel is a widely recognised strategy for promoting active living but its co-benefits beyond increasing physical activity, such as broader health, environmental, and social benefits, have rarely been synthesised. We conducted a systematic review to examine the co-benefits of active travel interventions. Following a preregistered protocol (PROSPERO CRD42022359059), we identified 80 studies for the search period from Jan 1, 2000, to Sept 13, 2022.

Physical Activity Report Card Indicators and the United Nations Sustainable Development Goals: Insights From Global Matrix 4.0.

Background: The World Health Organization recognizes that physical activity (PA) during childhood is crucial for healthy development, aligning well with the achievement of several United Nations (UN) Sustainable Development Goals (SDGs). This study aimed to explore the associations between 10 key indicators of PA for children and adolescents assessed in the Global Matrix 4.0 project, and the UN SDGs.

Exploring the effect of sedentary behavior on increased adiposity in middle-aged adults.

Background: Sedentary behavior is linked to excess fat mass; however, this association may be inconclusive due to potential measurement errors in self-reported sedentary behavior.

Objective: To assess the association between changes in sedentary behavior and fat mass in a Cohort of Health Workers (HWCS) from 2004 to 2010.

Methods: A total of 1,285 adults participating in the Cohort of Health Workers were evaluated in 2004 and 2010.

Who Benefits? A Mixed Methods Study Assessing Community Use of a Major Metropolitan Park During the COVID-19 Pandemic.

By providing spaces for recreation, physical activity, social gatherings, and time in nature, urban parks offer physical, mental, and social benefits to users. However, many urban residents face barriers to park use. The COVID-19 pandemic introduced new potential barriers to urban park access and use, including changes to daily life and employment, closure of park amenities and restrictions to public movement, and risk from the coronavirus itself.

Examining associations between physical activity context and children meeting daily physical activity guidelines: the role of outdoor play, sports, and other organized activities.

Background: Less than one-quarter of US children meet physical activity (PA) guidelines. Understanding the context in which PA occurs and how these contexts may play a role in meeting PA guidelines is an essential step toward developing effective behavioral interventions. The purpose of this study was to examine associations between PA context (sports participation, participation in other organized physical activities, active travel to school, and outdoor play) and the number of days children met PA guidelines in a representative sample of children living in Texas.

Who shops at their nearest grocery store? A cross-sectional exploration of disparities in geographic food access among a low-income, racially/ethnically diverse cohort in Central Texas.

We examined whether Central Texans shop at their nearest supermarket, how far they travel for groceries, and explored differences by race/ethnicity, urbanicity, motivations for store selection and other demographic characteristics. Using cross-sectional data and GIS, continuous network distances from participants' homes to nearest and usual supermarkets were calculated and multivariate linear regression assessed differences. <19% shopped at their nearest supermarket.

Structural Racism, Residential Segregation, and Exposure to Trauma: The Persistent Impact of Redlining.

Introduction: As part of New Deal era federal housing policy, the Home Owners Loan Corporation (HOLC) developed maps grading US neighborhoods by perceived financial security. Neighborhoods with high concentrations of racial and ethnic minorities were deemed financially unstable and denied federal investment, a practice colloquially known as redlining. The aim of this study was to assess the association of historical redlining within Austin, Texas to spatial patterns of penetrating traumatic injury.

Development, scoring, and reliability for the Microscale Audit of Pedestrian Streetscapes for Safe Routes to School (MAPS-SRTS) instrument.

Background: Active commuting to school can be a meaningful contributor to overall physical activity in children. To inform better micro-level urban design near schools that can support active commuting to school, there is a need for measures that capture these elements. This paper describes the adaptation of an observational instrument for use in assessing micro-scale environments around urban elementary schools in the United States.

Physical Activity Intervention for Urban Black Women With Asthma: Protocol for a Randomized Controlled Efficacy Study.

Background: Black women experience a higher prevalence of poor asthma outcomes and physical inactivity than their White counterparts. Black women comprise a particularly vulnerable group of patients with asthma, with some of the highest rates of asthma in adults, high health care use (emergency department visits and hospitalizations), and the highest crude asthma mortality rate of all race or ethnicity groups. Despite recommendations to engage in regular physical activity, fewer than 15% of Black women meet the 2008 National Physical Activity Guidelines, the lowest of all racial subgroups of adults.

Shaping Policy and Practice: Analyzing the Reach of Highly Cited and High Altmetrics Publications for Broader Impact on Physical Activity.

Background: A significant gap remains between the availability of physical activity (PA) evidence-based interventions and their application in real-world settings in policy and practice areas. This study aims to describe highly cited and high altmetrics publications in PA research and explore their impact on PA policy and practice.

Methods: Mixed-methods sequential explanatory study including the identification and description of the top highly cited and high altmetrics PA publications from the last 10 years (including study design, population, type of PA study, number of citations, and altmetrics score), and interviews with key informants regarding research dissemination and implications on PA policy and practice.

Rationale for the evaluation of renal functional reserve in allogeneic stem cell transplantation candidates: a pilot study.

Background: The main purpose of our study was to evaluate the ability of renal functional reserve (RFR) to stratify the risk of acute kidney injury (AKI) occurrence within 100 days of hematopoietic stem cell transplantation (HSCT) and to predict any functional recovery or the onset of chronic kidney disease. A secondary aim was to identify the clinical/laboratory risk factors for the occurrence of AKI.

Methods: The study design is prospective observational.

Examining Place-Based Neighborhood Factors in a Multisite Peer-Led Healthy Lifestyle Effectiveness Trial for People with Serious Mental Illness.

People with severe mental illness (SMI) experience significantly higher obesity-related comorbidities and premature mortality rates than healthy populations. The physical and social characteristics of neighborhoods where people with SMI reside can play an important role in promoting or hindering healthy eating and physical activity. However, this is seldom considered when designing and testing health behavior interventions for these populations.

Public health research on physical activity and COVID-19: Progress and updated priorities.

• Research produced during the pandemic showed pre-diagnosis physical activity was associated with substantially lower risk of severe coronavirus disease 2019 (COVID-19) outcomes. • Pandemic restrictions on common places for physical activity were associated with decreased physical activity and increased sedentary behavior. • There were few studies of interventions to increase physical activity during the pandemic, the role of physical activity in COVID-19 inequities, and built environment contributions to COVID-19 outcomes.
