Abstract Background Despite national-level initiatives to encourage active transport (AT) in New Zealand since 2005, rates of AT have continued to decline in most parts of the country, with negative impacts on health and the environment. This article describes the development of key policy recommendations for increasing AT in New Zealand. The goal was to establish a cohesive set of priority recommendations to inform AT decision-making in central and local government, district health boards, publ...

Abstract The purpose of this research was to evaluate a population level mass media campaign using implicit (i.e., automatic) and explicit (i.e., non-automatic) measures of evaluations and to determine if discrepant or summed evaluations were associated with endorsing campaign objectives: that physical activity can improve relationship-related, mind-related, or body-related outcomes. Participants (N = 1600) completed an online survey which included a single-category implicit association task tha...

Abstract Objectives School-based daily physical activity (DPA) policies represent a promising intervention for increasing physical activity levels among children. Between 2005 and 2010, five Canadian provinces adopted and implemented DPA policies. This national case study explored facilitators and challenges to developing, adopting and implementing DPA policies from the perspective of key stakeholders (‘policy-influencers’) in these five provinces. Methods Development, adoption and implementatio...

Abstract Background Parental perceptions towards different modes of transport correlate with adolescents’ mode choice for school trips. Whether parental attitudes differ for walking versus cycling and/or home-to-school distance is unknown. We compared parental perceptions of walking versus cycling to school in adolescents in Dunedin, New Zealand and examined whether mode-specific barriers differ by distance to school. Methods Parents (n = 341; age: 47.5 ± 5.2 years; 77.1% females) completed a su...

BACKGROUND: We evaluated a cohort of 35 children diagnosed with long QT syndrome, catecholaminergic polymorphic ventricular tachycardia, hypertrophic cardiomyopathy, or arrhythmogenic right ventricular cardiomyopathy with regard to physical and psychosocial well-being. MATERIAL AND METHODS: Patients wore an accelerometer to record their time involved in moderate- to vigorous-intensity physical activity and completed the Pediatric Quality of Life Inventory and the Pediatric Cardiac Quality of Lif...

Introduction Natural experiments are considered a priority for examining causal associations between the built environment (BE) and physical activity (PA) because the randomised controlled trial design is rarely feasible. Few natural experiments have examined the effects of walking and cycling infrastructure on PA and active transport in adults, and none have examined the effects of such changes on PA and active transport to school among adolescents. We conducted the Built Environment and Active...

OBJECTIVE: To propose a new anthropometric index that can be employed to better predict percent body fat (PBF) among young adults and to compare with current anthropometric indices. DESIGN: Cross-sectional. SETTING: All measurements were taken in a controlled laboratory setting in Seoul (South Korea), between 1 December 2015 and 30 June 2016. PARTICIPANTS: Eighty-seven young adults (18-35 years) who underwent dual-energy x-ray absorptiometry (DXA) were used for analysis. Multiple regression anal...

Context This scoping review examines the literature as it relates to autonomous vehicles and impact on movement behavior (i.e., physical activity, sedentary behavior, and sleep) or mode choice (e.g., public transit), beliefs about movement behavior or mode choice, or impact on environments that may influence movement behavior or mode choice. Evidence acquisition A search was conducted in June 2018 and updated in August 2019 of numerous databases (e.g., SPORTDiscuss, PubMed, and Scopus) and hand ...

Objective Exercise is an effective modality for the prevention and treatment of chronic conditions and family physicians are the healthcare providers tasked to manage patients’ chronic disease status. However, little is known about the exercise documentation in family-physician records. Therefore, a scoping review was conducted to describe family-physician-recorded exercise-related advice to patients in electronic medical records. Design Scoping review. Setting Primary care clinics. Search strat...
