Purpose: This study examines the usefulness of complementing accelerometry-based physical activity measurement with spatial data from portable global positioning system (GPS) units to determine where occurs. Methods: First, using geographic distribution points and Bland–Altman plots, we examined GPS units' validity interunit reliability by measuring distance a geodetic point. We also assessed comparing collected in three built environment contexts. Second, conducted pilot which 35...
The primary aim of this pilot study was to assess how well the combination global positioning system (GPS) and accelerometer data predicted different activity modes.Ten adults (seven male, three female; 23-51 yr) simultaneously wore a GPS unit during bouts walking, jogging/running, bicycling, inline skating, or driving an automobile. Discriminant function analysis used identify parsimonious variables derived from counts steps speed that best classified mode. A total 29 were develop...
Background: To determine how trail characteristics may influence use, reliable and valid audit tools are needed. Methods: The Path Environment Audit Tool (PEAT) was developed with design, amenity, aesthetics/maintenance items. Two observers independently audited 185 segments at 6 Massachusetts facilities. GPS-derived items were used as a “gold standard.” Kappa (k) statistics, observed agreement intraclass correlation coefficients (ICCs) calculated to assess inter-observer reliability...
To assess test-retest reliability and validity of the Youth Risk Behavior Survey (YRBS) items for moderate vigorous physical activity in middle school students.Students (N = 125; 12.7 +/- 0.6 yr) wore Actigraph accelerometers 6.1 1.0 d twice completed surveys that included YRBS items. Accelerometer counts were transformed into minutes (3-6 METs) (> 6 activity. Days per week meeting recommendations estimated using four summary methods. Reliability was assessed intraclass correlation...
We evaluated the association between county sprawl index, a measure of residential density and street accessibility, physical activity body mass index (BMI).We conducted multilevel cross-sectional analysis in sample Nurses' Health Study participants living throughout United States 2000 to 2001 (n = 136 592).In analyses adjusted for age, smoking status, race, husband's education, 1-SD (25.7) increase (indicating denser, more compact county) was associated with 0.13 kilograms per meters...
There is need for a youth-informed conceptualization of how environmental and social neighborhood contexts influence physical activity. We assessed youths' perceptions their peer environments as affecting Thirty-three students (20 girls; ages 12-14 years) participated in focus groups about the environment peers within neighborhoods, understanding they affect Inductive analysis identified themes access (e.g., to equipment); aesthetics; safety; proximity behavior bullying); adult support or...
Objective: To determine the effect of a school-based intervention to promote healthful nutrition and physical activity on disordered weight-control behaviors (selfinduced vomiting or use laxatives diet pills control weight) in early adolescent girls boys.Design: Using group-randomized, controlled-trial design, we randomly assigned middle schools an condition.Multivariate logistic regression analyses were used assess odds reporting new case at follow-up, adjusting for sex, school-level...
OBJECTIVES: To develop a comprehensive inventory of state physical education (PE) legislation, examine trends in bill introduction, and compare factors. METHODS: State PE legislation from January 2001 to July 2007 was identified using legislative database. Analysis included components evidence-based school the Community Guide other authoritative sources: minutes PE, activity, teacher certification, an environmental element, including facilities equipment. Researchers abstracted information...
There are few studies of built environment associations with physical activity and weight status among older women in large geographic areas that use individual residential buffers to define environmental exposures. Among 23,434 (70.0 ± 6.9 yr; range = 57-85) 3 states, relationships between objective variables meeting recommendations via walking were examined. Differences by population density state explored stratified models. Population (odds ratio [OR] =1.04 [1.02, 1.07]), intersection...
The built environment predicts walking in older adults, but the degree to which associations between objective and for different purposes are mediated by environmental perceptions is unknown. We examined neighborhood leisure utilitarian mediation perceived among women. Women (N = 2732, Mage 72.8 ± 6.8 years) from Massachusetts, Pennsylvania, California completed a survey. Objective population intersection density of stores services variables were created within residential buffers. Perceived...
Active transportation to and from school (ATS) is a viable strategy help increase physical activity among youth. ATS can be challenging because initiatives require transdisciplinary collaboration, are influenced by the built environment affected numerous policies. The purpose of this study identify policies factors that influence initiatives. Nine elementary schools in seven states participated case study. Sixty-nine stakeholders were interviewed. interviews transcribed, coded analyzed using...
Dog walking is associated with higher levels of physical activity (PA). However, not all dog owners walk their dog(s) at a level sufficient for health benefits. Therefore, identifying correlates dog-walking may help to inform the design more effective interventions promote this specific form PA. The purpose study was examine psychosocial and environmental relationships overall In 2010, 391 (mean age = 43.6 ± 12.3 years) completed survey. Multiple logistic regression structural equation...
Background: This report presents the effectiveness of Massachusetts Well-Integrated Screening and Evaluation for Women Across Nation (WISEWOMAN) Project (MWWP) in reducing cardiovascular disease (CVD) risk uninsured underinsured women aged ≥50. Methods: Healthcare sites were randomly assigned to an enhanced intervention (EI) or minimum (MI). enrolled at all received CVD factor screening, onsite counseling, education, referral, follow-up as needed. EI additional services specially designed...
Purpose: Most built environment studies have quantified characteristics of the areas around participants' homes. However, environmental exposures for physical activity (PA) are spatially dynamic rather than static. Thus, merged accelerometer and global positioning system (GPS) data were utilized to estimate associations between PA among adults. Methods: Participants (N = 142) recruited on trails in Massachusetts wore an GPS unit 1–4 days. Two binary outcomes created: moderate-to-vigorous...
