Evidence is beginning to accumulate that purpose-built bicycle-specific facilities reduce crashes and injuries among cyclists, providing the basis for initial transportation engineering guidelines for cyclist safety. Street lighting, paved surfaces, and low-angled grades are additional factors that appear to improve cyclist safety.

A bicycle barometer is a digital display of the numbers of people on bicycle in the bike lane, summarizing volumes for the day and the annual cumulative total. The purpose of the barometer is to encourage more people to ride their bikes by showing how many bicycle riders have been counted, and to also capture data on bicycle usage.

Intrinsic motivation for exercise among adolescents may be enhanced when the environment supports perceived competence, relatedness, and autonomy, and when adolescents participate in activities that they find enjoyable.

The small number of studies on the interrelationship of BMI, fitness and physical activity emphasizes the need for longitudinal studies that would reveal 1) the causality between physical activity and overweight / fitness and overweight and 2) the causal interrelationships among overweight, physical activity and fitness. These results must be carefully interpreted given the lack of distinction between self-reported and objective physical activity and that studies analyzing the metabolic syndrome or cardiovascular disease were not considered. The importance of physical activity or fitness in predicting overweight remains unknown.

School safety zones that reduce automobile speed to 20mph cover a 300m radius around each school, yet the average distance to school is 1.8 km. This article argues that this radius only covers 17% of the journeys that students take if they walk or bike to school. Therefore, school safety zones provide little protection. Instead, the authors suggest that we should ensure that children are given better conditions for walking and cycling for the whole route from their home to school by creating community wide 20mph speed limit zones…

Behavioral interventions increased free-living PA/exercise and produced clinically significant improvements in long-term glucose control. Future studies should consider use of theory and multiple behavior change techniques associated with clinically significant improvements in HbA1c, including structured training for care providers on the delivery of behavioural interventions.

PCD Volume 10 April 25th (2013)
This week Preventing Chronic Disease (PCD) released 8 articles focusing on multiple chronic conditions. The articles within this collection address the current trends in population growth, age distribution, and disease dynamics that forecast rises in the prevalence of chronic diseases, other chronic conditions, and combinations of chronic conditions.


This document is meant to anchor discussions at a May 2013 National Recreation Roundtable in New Brunswick, which is one step along the process of developing a National Recreation Agenda. That event will also explore the alignment of any shared initiatives between Active Canada 20/20, the Canadian Sport Policy, and the National Recreation Agenda.

This series of maps shows the percentages of the U.S. population medically defined as obese.

In 2003, 22.3 per cent of the population was estimated to be obese, and that percentage has climbed to an average of 25.3 per cent.

Few researchers have considered older adult men’s experiences with physical activity. Older adult men represent one of the least active demographic groups. Identifying elements of exercises programs that older adult men consider appealing holds the potential to inform our understanding of the activity levels demonstrated by this demographic.

“Maturing.”  “Ripening.”  “Evolving.” Call “aging” what you will, but supporting an aging population is becoming a major concern for governments, societies and communities across the globe. Now, new research from collaborators in the School of Public Health sheds light on the challenges seniors face in Edmonton neighbourhoods.

The alternative therapies rarely caused serious side effects and posed few health risks. All three types of exercise reduced blood pressure……..

This report highlights exemplary policy language, and provides leaders at all levels of government with ideas for how to create strong Complete Streets policies. Information about additional resources for local leaders is also included.

Infographic  that looks at the key factors contributing to the decline of suburbia.

Note: Big document (257 pages). This project reviewed available research to determine the underlying relationships between households, firms and travel demand and then turned these relationships into a regional scenario planning tool that can be used to evaluate the impacts of various smart growth policies.

► Supervised physical activity plus diet interventions were the most effective. ► Innovative strategies to maximize the intervention effect should be developed. ► Interventions are needed to start during pregnancy and continue during postpartum.
