Abstract: Household factors (electronic media equipment, play equipment, physical activity in the home, and social support) have been associated with childhood moderate- to vigorous-intensity physical activity (MVPA), but little is known about how these factors differ across erse countries. The objective was to explore household correlates of objective MVPA in children from 12 countries. Overall, 5,859 nine- to eleven-year-old children from 12 countries representing a range of human and socioeconomic development indicators wore an accelerometer for 7 days and parents reported on household factors. Multilevel general linear models explored associations among household factors and MVPA variables controlling for age, sex, and parental education. Across sites, children with at least one piece of bedroom electronic media had lower MVPA (∼4 min/day P < 0.001) than those who did not. More frequent physical activity in the home and yard, ownership of more frequently used play equipment, and higher social support for physical activity were associated with more MVPA (all P < 0.001). The association between play equipment ownership and MVPA was inconsistent across countries (interaction P < 0.01). With the exception of play equipment ownership, modifiable household factors showed largely consistent and important associations with MVPA across high-, mid-, and low-income countries.

Abstract: The present study evaluated awareness of the Canadian Society for Exercise Physiology’s 2011 Canadian Physical Activity Guidelines for Adults and assessed correlates. Reported awareness of the physical activity (PA) guidelines was 12.9% (204/1586) of the total s le surveyed. More than half (55%) self-reported meeting PA guidelines of ≥ 150 min of moderate to vigorous PA per week. Awareness of PA guidelines was significantly related to participants’ level of PA (χ 2 (1) = 30.63, p 0.001, φ = –0.14), but not to any demographic variables.

Abstract: To develop sex-specific and age-specific international norms for the 20 m shuttle run test (20mSRT) in children and youth (aged 9-17 years), and to estimate the prevalence meeting the FITNESSGRAM criterion-referenced standards for healthy cardiorespiratory endurance (CRE). A systematic review was undertaken to identify papers explicitly reporting descriptive 20mSRT (with 1 min stages) data on children and youth since 1981. Data were included on apparently healthy (free from known disease/injury) 9-17 years old. Following standardisation to a common metric and for protocol differences, pseudo data were generated using Monte Carlo simulation, with population-weighted sex-specific and age-specific normative centiles generated using the Lambda Mu and Sigma (LMS) method. Sex-related and age-related differences were expressed as per cent and standardised differences in means. The prevalence with healthy CRE was estimated using the sex-specific and age-specific FITNESSGRAM criterion-referenced standards for [Formula: see text]. Norms were displayed as tabulated centiles and as smoothed centile curves for the 20mSRT using 4 common metrics (speed at the last completed stage, completed stages/minutes, laps and relative [Formula: see text]). The final data set included 1 142 026 children and youth from 50 countries, extracted from 177 studies. Boys consistently outperformed girls at each age group (mean difference±95% CI: 0.86±0.28 km/h or 0.79±0.20 standardised units), with the magnitude of age-related increase larger for boys than for girls. A higher proportion of boys (mean±95% CI: 67±14%) had healthy CRE than girls (mean±95% CI: 54±17%), with the prevalence of healthy CRE decreasing systematically with age. This study provides the most comprehensive and up-to-date set of international sex-specific and age-specific 20mSRT norms for children and youth, which have utility for health and fitness screening, profiling, monitoring and surveillance.

Abstract: The aim of this review was to consolidate and synthesize existing evidence regarding current knowledge and awareness of the Canadian Physical Activity (PA) and Sedentary Behaviour (SB) Guidelines. MEDLINE, Embase, and PsycINFO were searched for peer-reviewed publications pertaining to the guidelines. Content experts, key organizations (i.e., ParticipACTION and the Canadian Fitness and Lifestyle Research Institute), journal Web sites, and service organizations (i.e., the Canadian Society for Exercise Physiology (CSEP) and the Public Health Agency of Canada) were consulted for additional evidence. Scientific publications (n = 6) and research from ParticipACTION and the Canadian Fitness and Lifestyle Research Institute reported that awareness of the guidelines is low, especially with respect to the SB guidelines. Less than 10% of survey respondents from the Canadian population were aware of the PA guidelines, and less than 5% were aware of the SB guidelines. Information on the guidelines was available on 51% of public health unit and CSEP partner Web sites. Online metrics (e.g., downloads, site accessions) from CSEP, the Public Health Agency of Canada, and journal Web sites showed that online accession of the guidelines was high (e.g., all “highly accessed” on journal Web sites). This review showed that awareness of the Canadian PA and SB Guidelines is low among the general population but higher among the scientific and stakeholder communities. Governmental, nongovernmental, and stakeholder organizations should collaborate in creating sustained, long-term, and well-resourced communication plans to reach the Canadian population to raise awareness of PA and SB guidelines and should implement programs to facilitate their uptake.
