The impact of the Vancouver Winter Olympics on population level physical activity and sport participation among Canadian children and adolescents: population based study

Background There has been much debate about the potential impact of the Olympics. The purpose of this study was to determine if hosting the 2010 Vancouver Olympic Games (OG) encouraged Canadian children to be physically active. Methods Children 5�19 years (n?=?19862) were assessed as part of the representative Canadian Physical Activity Levels Among Youth surveillance study...

Relationship between parent and child pedometer-determined physical activity: a sub-study of the CANPLAY surveillance study

Background Understanding parental influences on their children’s physical activity (PA) provides insight into developing effective family-based interventions. This study examines whether children’s objectively monitored PA is associated with that of their parents. Methods Participants (children and parents) were recruited to a sub-study of the Canadian Fitness and Lifestyle...

ParticipACTION: Overview and introduction of baseline research on the "new" ParticipACTION

Background This paper provides a brief overview of the Canadian physical activity communications and social marketing organization "ParticipACTION"; introduces the "new" ParticipACTION; describes the research process leading to the collection of baseline data on the new ParticipACTION; and outlines the accompanying series of papers in the supplement presenting the detailed...

The place of physical activity in the WHO Global Strategy on Diet and Physical Activity

In an effort to reduce the global burden of non-communicable disease, the World Health Organization released a Global Strategy for Diet and Physical Activity in May 2004. This commentary reports on the development of the strategy and its importance specifically for physical activity-related work of NGOs and researchers interested in increasing global physical activity...

ParticipACTION: A mass media campaign targeting parents of inactive children; knowledge, saliency, and trialing behaviours

Background In late 2007, Canada's ParticipACTION national physical activity mass media campaign was re-launched, with an initial campaign targeting parents of elementary school-aged children. The campaign informed them about the risks of physical inactivity for children and youth. The purpose of this study was to assess campaign awareness and understanding following the campaign...

Non-response bias in physical activity trend estimates

Background Increases in reported leisure time physical activity (PA) and obesity have been observed in several countries. One hypothesis for these apparently contradictory trends is differential bias in estimates over time. The purpose of this short report is to examine the potential impact of changes in response rates over time on the prevalence of adequate PA in Canadian adults...

Distinct trajectories of leisure time physical activity and predictors of trajectory class membership: a 22 year cohort study

Background Prospective studies linking social factors to long term patterns of physical activity are lacking. In this 22 year longitudinal study, we seek to identify long term patterns of involvement in leisure time physical activity (LTPA), and explore socioeconomic and demographic predictors of distinct LTPA trajectories. Methods Among 2102 individuals aged 18–60 years in 1981...

Patterns of neighborhood environment attributes related to physical activity across 11 countries: a latent class analysis

Background Neighborhood environment studies of physical activity (PA) have been mainly single-country focused. The International Prevalence Study (IPS) presented a rare opportunity to examine neighborhood features across countries. The purpose of this analysis was to: 1) detect international neighborhood typologies based on participants’ response patterns to an environment survey...

The International Prevalence Study on Physical Activity: results from 20 countries

Background Physical activity (PA) is one of the most important factors for improving population health, but no standardised systems exist for international surveillance. The International Physical Activity Questionnaire (IPAQ) was developed for international surveillance. The purpose of this study was a comparative international study of population physical activity prevalence...

Perceived neighborhood environment and physical activity in 11 countries: Do associations differ by country?

Background Increasing empirical evidence supports associations between neighborhood environments and physical activity. However, since most studies were conducted in a single country, particularly western countries, the generalizability of associations in an international setting is not well understood. The current study examined whether associations between perceived attributes...

How many steps/day are enough? For older adults and special populations

Older adults and special populations (living with disability and/or chronic illness that may limit mobility and/or physical endurance) can benefit from practicing a more physically active lifestyle, typically by increasing ambulatory activity. Step counting devices (accelerometers and pedometers) offer an opportunity to monitor daily ambulatory activity; however, an appropriate...
