“…These findings are consistent with a previous study conducted among 5–6 year-old Dutch children [28]. For 6-year-old children, physical activity guidelines state that children should be active for at least 60 minutes per day at a moderate to vigorous level in order to convey beneficial health effects [23-25]. Since we did not have any information on actual physical activity levels during outdoor play, it is possible that children were not physically active enough during outdoor play to find any effects on children’s body fat [41].…”

“…Future studies should aim at incorporating objectively measured physical activity (i.e., by accelerometry and direct observation) in order to obtain more information about time spent in different activity levels and physical activity behaviors across the whole day. Finally, data on sedentary behaviors and physical activity behaviors were dichotomized according to current guidelines and recommendations [6,22-25]. This may have potentially led to a loss of information and statistical power to detect associations.…”

“…Similar to television viewing and computer game use, frequency and duration of outdoor play were assessed for weekdays and weekend days separately and combined to estimate daily outdoor play using the same formula (i.e., estimated total weekly hours divided by 7 days). Daily outdoor play was dichotomized into <1 hour/day versus ≥1 hour/day according to physical activity guidelines stating that children should acquire at least one hour of moderate to vigorous physical activity (MVPA) per day [23-25]. For active transport, number of days on which the children walked to/from school (0–5 days) and number of days children cycled to/from school (0–5 days) were assessed.…”

BackgroundChildhood overweight and obesity is a major public health concern. Knowledge on modifiable risk factors is needed to design effective intervention programs. This study aimed to assess associations of children’s sedentary behaviors (television viewing and computer game use) and physical activity behaviors (sports participation, outdoor play, and active transport to/from school) with three indicators of body fat, i.e., percent fat mass, body mass index (BMI) standard deviation scores, and weight status (normal weight, overweight).MethodsCross-sectional data from 5913 6-year-old ethnically diverse children were analyzed. Children’s weight and height were objectively measured and converted to BMI. Weight status was defined according to age- and sex-specific cut-off points of the International Obesity Task Force. BMI standard deviation scores were created, based on Dutch reference growth curves. Fat mass was measured my dual-energy X-ray absorptiometry (DXA). Sedentary and physical activity behaviors were assessed by parent-reported questionnaires. Series of logistic and linear regression analyses were performed, controlling for confounders (i.e., socio-demographic factors, family lifestyle factors, and other sedentary behaviors and physical activity behaviors).ResultsSports participation was inversely associated with fat mass (p < 0.001), even after adjustment for socio-demographic factors, family lifestyle factors, and other sedentary behaviors and physical activity behaviors. No other independent associations were observed.ConclusionsThe results of this study indicate that sports participation is inversely associated with percent body fat among ethnically diverse 6-year-old children. More research in varied populations including objective measurements and longitudinal designs are needed to confirm these current results.

“…These two items assessed the total amount of physical activity participants engaged in over the past week and over a typical week. These two items were summed and divided by 2 to get an average number of days per week that participants completed physical activity for at least 60 min [25,26]. Scores derived from this two-item measure demonstrated acceptable reliability at all four time points [Spearman-Brown coefficient ρ values ≥0.82; 27].…”

The objective of this study was to assess changes in adolescent girls' health-enhancing cognitions and behaviors targeted by the Go Girls! group-based mentorship lifestyle program. Three hundred and ten adolescent girls (nested within 40 Go Girls! groups) completed questionnaires that assessed cognitions (attitudes, self-regulatory efficacy, and intentions) and behaviors (physical activity and dietary) at four time points (two pre-program, one at the end of the program, and one at 7-week follow-up [5]. In response to these public health concerns, genderspecific lifestyle interventions have been developed for adolescent girls that target health behaviors, such as physical activity and dietary behaviors, and cognitions toward those behaviors.The majority of gender-specific lifestyle interventions for youth have tended to focus on the prevention or treatment of obesity [e.g., 6, 7]. For example, Neumark-Sztainer and colleagues [8] examined the effectiveness of a physical education program entitled "New Moves" to target health behaviors and body image among adolescent girls at risk of overweight and obesity. Results from this study [8] indicate that after completing the program, girls reported significant improvements in portion control, reductions in sedentary behavior, and increases in their physical activity self-efficacy and self-reported psychological "stage of change" for both dietary and physical activity behaviors. However, no significant changes were found for physical activity behavior or quality of dietary intake in terms of consumption of fruit and vegetables and sugar-sweetened beverages. Similarly, findings from another school-based lifestyle program for adolescent girls indicated improvements in girls' health behavior intentions and dietary knowledge, but no changes in physical activity or dietary behavior after completing the program [9].In light of the limited effectiveness of these programs, theory-based research is needed to target behavior change. Specifically, the social context has

Background: Cardiac rehabilitation (CR) promotes long-term positive health behaviours, such as physical activity (PA), in patients following a cardiovascular event. We have limited knowledge of long-term PA and its correlates. Therefore, this research examined both PA behaviour and socioecological correlates among elderly graduates 2-6 years following CR. Hypothesis: CR graduates will have a moderate PA level in the long term. Greater PA will be associated with various multilevel correlates.Methods: This was a retrospective, cross-sectional study which quantified PA using the Physical Activity Scale for the Elderly (PASE) and collected information about socioecological correlates at the intrapersonal, interpersonal and health service levels. Both univariate and multivariate analyses assessed PA and PA correlates. Results: The majority of the 584 participants were older (69.8 ± 9.8), male (80.3%), and well educated (75.4% ≥ some post-secondary). Average time since CR graduation was 41.5 ± 11.5 months. Seventy five percent of CR graduates reported current weekly PA levels that met, or exceeded, Canadian PA guidelines (>150 minutes of moderate-vigorous PA). Univariate analyses identified 13 PASE score correlates. Multivariate analyses identified age, PA enjoyment, current work status, CR staff support, location of primary residence, and perceived health as significantly associated with higher PASE scores (p < 0.001).Conclusions: Three and a half years post-CR graduates had high PA levels. Greater PA was associated with several modifiable multilevel correlates at all levels of influence. Understanding correlates of long-term PA behaviour among CR graduates will help identify groups at risk for nonadherence and assist with continued program development. IntroductionCompared to patients who only receive conventional inhospital care, patients who complete a cardiac rehabilitation (CR) program following a cardiac event experience a significant reduction in all-cause mortality 1 -3 by 20% to 25% within 3 years. 3 CR programs are traditionally short-term multifaceted interventions that include physical activity (PA) as a core element. 2,4,5 One of the overarching objectives of CR is to encourage patients to maintain PA at guidelinerecommended levels after program completion. Current Canadian PA guidelines for effective health advocate at least 150 minutes of moderate-vigorous PA per week. 6 There is some evidence that states that PA behavior among CR graduates in the short term (1 year post-CR) often fails toThe authors have no funding, financial relationships, or conflicts of interest to disclose. meet the recommendations. 7,8 There is very little evidence on PA behavior over the long term (2 or more years).Encouraging positive health behaviors among CR graduates is a complex process that involves many levels of influence. To examine these levels of influence, a comprehensive approach to health promotion must be employed, such as the socioecological model. 9 The socioecological model integrates intra-and interpersonal fa...
