Thus, it is important to develop and provide the best methods for assessing aspects of parks that could influence physical activity. This study examined the use of high-tech video capture for describing park quality.

Direct Observation of COVID-19 Prevention Behaviors and Physical Activity in Public Open Spaces.

Mask wearing and physical distancing are effective at preventing COVID-19 transmission. Little is known about the practice of these behaviors during physical activity (PA). In this longitudinal study, direct observation was used to describe COVID-19 prevention behaviors among physically active individuals.

A comprehensive evaluation of physical activity on sidewalks and streets in three U.S. Cities.

A considerable proportion of outdoor physical activity (PA) is done on sidewalks/streets. The purpose of the current study was to create a comprehensive picture of PA and non-PA (sitting and standing) occurring on sidewalks/streets. A wearable video device was used to capture videos during 2019 in three different size (small, medium, large), U.

A Direct Observation Video Method for Describing COVID-19 Transmission Factors on a Micro-Geographical Scale: Viral Transmission (VT)-Scan.

The COVID-19 pandemic severely affected many aspects of human life. While most health agencies agree mask wearing and physical distancing reduce viral transmission, efforts to improve the assessment of these behaviors are lacking. This study aimed to develop a direct observation video method [Viral Transmission (VT)-Scan] for assessing COVID-19 transmission behaviors and related factors (e.

Validation of the Block Walk Method for Assessing Physical Activity occurring on Sidewalks/Streets.

The block walk method (BWM) is one of the more common approaches for assessing physical activity (PA) performed on sidewalks/streets; however, it is non-technical, labor-intensive, and lacks validation. This study aimed to validate the BWM and examine the potential for using a wearable video device (WVD) to assess PA occurring on sidewalks/streets. Trained observers (one wearing and one not wearing the WVD) walked together and performed the BWM according to a previously developed protocol along routes in low, medium, and high walkable areas.

Steady State Hydration Levels of Career Firefighters in a Large, Population-Based Sample.

Objectives: To establish the extent of steady state hypohydration among firefighters and examine factors associated with their hydration status.

Methods: Data on 450 career firefighters from 11 randomly selected fire departments had their body composition, total body water (TBW), and hypohydration status assessed using bioelectrical impedance. Measured height and weight were used to determine body mass index (BMI) and weight classification.

Physical Activity Assessment Between Consumer- and Research-Grade Accelerometers: A Comparative Study in Free-Living Conditions.

Background: Wearable activity monitors such as Fitbit enable users to track various attributes of their physical activity (PA) over time and have the potential to be used in research to promote and measure PA behavior. However, the measurement accuracy of Fitbit in absolute free-living conditions is largely unknown.

Objective: To examine the measurement congruence between Fitbit Flex and ActiGraph GT3X for quantifying steps, metabolic equivalent tasks (METs), and proportion of time in sedentary activity and light-, moderate-, and vigorous-intensity PA in healthy adults in free-living conditions.

Objectives: To examine the association between self-efficacy, social support, and fear of movement with physical activity and function at baseline and after 12 weeks of physical therapy.

Design: Nonrandomized cohort study, repeated-measures design.

Setting: Outpatient rehabilitation clinic within the general community.

Sustainability of physical activity promoting environments and influences on sustainability following a structural intervention in residential children's homes.

Research examining sustainability of health promotion programs within organizational settings is limited. The Environmental Interventions in Residential Children's Homes (ENRICH) was a structural intervention that trained Wellness Teams (WTs) within residential children's homes (RCH) to target environmental changes that promote physical activity (PA) among residential youth. This study examines the sustainability of PA promoting environments and influences on sustainability within RCHs.

Moderating Effects of Health Literacy on Change in Physical Activity Among Latinas in a Randomized Trial.

Introduction: Latinas report low rates of physical activity (PA) and are at risk for poor health outcomes. Language and literacy barriers impede access and utilization of PA-related resources. This study examined health literacy as a moderator on changes in moderate-to-vigorous physical activity (MVPA) in 196 Latinas enrolled in Seamos Saludables, a randomized-controlled trial of a 6-month culturally and linguistically adapted PA print intervention

Methods: Secondary analyses were conducted on demographics, acculturation and generation status, and health literacy (Newest Vital Sign).

Classification tree analysis to examine influences on colorectal cancer screening.

Purpose: Identifying correlates of colorectal cancer screening (CRCS) is critical for cancer control and prevention. Classification tree analysis (CTA) is a potentially powerful analytic tool that can identify distinct population subgroups for which CRCS is influenced by any number of multivariable interactions. This study used CTA to identify correlates of CRCS for exclusive population subgroups.

Effects of a structural intervention and implementation on physical activity among youth in residential children's homes.

This study reports the effects of a structural intervention, ENRICH (Environmental Interventions in Children's Homes) which targeted the physical and social environment within residential children's homes (RCHs) to increase physical activity (PA) among residents (n=799). Participating RCHs (n=29) were randomized to Early (n=17) or Delayed (n=12) groups from 2004 to 2006 and 2006 to 2008, respectively. Children's PA was measured at three time periods (2004, 2006, 2008).

Understanding reversals of association between cancer screening and race/ethnicity.

Background: We used a composite variable composed of insurance status, income, and race/ethnicity to investigate access-enhancing programs as a possible reason for "reversals of association" and large percent changes (LPC), between race/ethnicity and cancer screening, when comparing the unadjusted and adjusted ORs.

Methods: Data were from women aged 40-64 years, using the combined 2008 and 2010 Behavioral Risk Factor Surveillance System surveys. Recent mammography was within the past 2 years, and recent Pap testing was within the past 3 years.

Health literacy predicts change in physical activity self-efficacy among sedentary Latinas.

Health literacy (HL) is associated with preventive health behaviors. Self-efficacy is a predictor of health behavior, including physical activity (PA); however, causal pathways between HL and self-efficacy for PA are unknown, especially among Latinas who are at risk for chronic disease. To explore this potential relationship, secondary analyses were conducted on data [Shortened Test of Functional Health Literacy in Adults (STOFHLA), PA self-efficacy, and socio-demographics] from a 6-month, randomized controlled trial of a print-based PA intervention (n = 89 Spanish-speaking Latinas).

Factors associated with physical activity literacy among foster parents.

Objectives: To explore associations between physical activity (PA) literacy and psychosocial constructs for providing instrumental social support for youth PA.

Methods: Ninety-one foster parents completed surveys assessing PA literacy (overall and specific), perceptions of child PA, coordination, PA enjoyment, psychosocial variables: positive/negative beliefs, normative beliefs, perceived behavioral control (PBC), and self-efficacy.

Results: Race, negative beliefs, PBC, and foster parent sport involvement were associated with specific PA literacy.

Developing scales to assess parental instrumental social support and influence on provision of social support for physical activity in children.

Background: An important influence on youth physical activity (PA) is the provision of instrumental social support (ISS) by parents and other adults. Limited research exists about factors that influence parental provision of ISS for youth PA. Following a theory-based conceptual model, a measure for assessing ISS for PA was developed from elicitation survey results.
