To evaluate the relationships between the time spent on sedentary activities (computer usage, video game playing, television viewing, and reading) and physical inactivity in a sample of youth (aged 12-19 years) from the 2000-2001 Canadian Community Health Survey.
The study sample included 7982 youth (4034 males, 3948 females) across Canada (mean age: 15.61 years, SD: 2.23 years). Weekly time spent on computers, video games, television, and reading during leisure-time was obtained through self-reported questionnaires. Physical inactivity was determined by respondents' daily energy expenditure assessed through a physical activity questionnaire. Multivariate logistic regression analysis was conducted to examine the relationship between sedentary activities and physical inactivity respectively by gender. Sociodemographic variables, health status, and overweight status were controlled in the analysis.
A substantial proportion of Canadian youth was inactive: 50.3% of males and 67.8% of females. Controlling for sociodemographic variables, health status, and body mass index, television viewing was significantly associated with physical inactivity for both males and females regardless of their overweight status. However, computer usage was associated with physical activity among males, and reading was associated with physical activity among females.
There is a complex inter-relationship between sedentary behaviors and physical inactivity, highlighting the need for targeted interventions addressing patterns of sedentary behavior engagement. Reducing time spent on television viewing may be one plausible strategy within such interventions in reducing physical inactivity among youth.

- "With regard to individual-level socio-demographic factors, a negative association has been identified between PA and age, with PA declines being steepest for female adolescents [14, 15]. In general, boys tend to be more active than girls in Canada16171819, but study results have been mixed . Research in Canada and the United States has also found that PA levels are lower among new and recent immigrants21222324252627. "

Physical activity during childhood is associated with a multitude of physical, behavioural, and psychological health benefits. Identification of effective population level strategies for increasing children's physical activity levels is critical for improving the overall health of Canadians. The overall objective of this study is to assess how a naturally-occurring, community-level intervention which offers Grade 5 children in London, Canada a free access pass to physical activity opportunities (facilities and programs) for an entire school year can lead to increased physical activity among recipients.
This study adopts a longitudinal cohort study design to assess the effectiveness of improving children's access to physical activity opportunities for increasing their physical activity levels. To meet our overall objective we have three aims: (1) to assess whether the provision of free access increases children's physical activity levels during and after the intervention compared to a control group; (2) to assess how and why child-specific trajectories of physical activity (between-children differences in level of physical activity measured across time) in the intervention group differ according to children's individual and household characteristics; and (3) to explore additional factors that are unaccounted for in the theoretical model to gain a further understanding of why the free access intervention had varying effects on changing physical activity levels. We will be addressing these aims using a mixed methods approach, including: a series of youth surveys conducted before, during, immediately after, and 4-months after the intervention; parent surveys before, during, and post-intervention; real-time tracking of the access pass use during the intervention; and focus groups at the conclusion of the intervention. Data compiled from the youth surveys will provide a subjective measure of physical activity to be used as our outcome measure to address our primary aims.
The results of this study can inform policy- and decision-makers about the sub-groups of the population that benefitted the most (or least) from the intervention to provide more specific information on how to develop and target future interventions to have a greater impact on the physical activity levels and overall health of children.

- "It is evident that gender differences existed for almost all the activities listed in the questionnaire. Gender differences in the participation in non-kinesiology related activities in their free time were also obtained in the following studies: Kolar (1993); McHale, Crouter, and Tucker (2001); Arbunić (2002); Babić (2003); Miller (2003); Salmon, Telford and Crawford (2004); Koezuka et al.

ABSTRACT: The aim of this study was to determine the differences in spending free time in kinesiology and non-kinesiology related activities between subsamples defined according to gender and age on the sample of students completing primary and attending lower secondary education. Daily physical exercise is very important for the health of children and youth. Failing to be involved in daily physical exercise and to participate in kinesiology related free time activities has become an important public health problem. This study was conducted on a convenience sample of boys and girls attending fifth to eighth grades. The total number of students who participated in the study was 847, of which 413 girls and 434 boys. A questionnaire, designed for the purpose of this research, was used to assess the level of students' activities in their free time. The significance of differences between subsamples defined according to gender was determined by Mann-Whitney U test, while the significance of age differences was determined by Kruskal Wallis test. The results of the Mann-Whitney U test confirmed the existence of statistically significant gender differences among fifth to eighth graders in the implementation of kinesiology and non-kinesiology related activities during free time. The analysis of kinesiology related activities shows that girls spend more time in the activities of walking, roller skating, playing badmiton, volleyball and dancing, while boys spend more free time cycling, playing football, basketball and handball. After analysing non-kinesiology related activities, it was established that boys are more interested in IT related activities (computer, playstation...) whose sole purpose is playing games and entertainment, while girls are more involved in activities that are fun, relaxing and educational. Significant age differences in the implementation of non-kinesiology related activities were also found among the students. The established difference is the most significant among age groups (younger and older students), but age differences are certainly also determined by natural laws of growth and development

- "The probable reason was the fact that in this test, there was no movement of the lower extremities and trunk and therefore it was not necessary to trigger the mass of the body in space, but the task performed by only the upper extremities. Daily physical exercise had for prediction of increasing levels of motor skills, which was positively correlated with body mass index (Biddle et al., 2005; Koezuka et al., 2006; Wrotniak et al., 2006; D' Hondt et al., 2009) . Also, daily physical activity is very important to maintain normal body weight but also in weight reduction. "

ABSTRACT: In the last two decades there has been an increase in the number of children who have increased body
weight or become obese. This statement confirms the fact that the affected population of children are not
only in developed countries, but also in those who have a lower economic standard. Therefore, strategies for
prevention and treatment of obesity have become a top priority for public health Aim of this study was to
determine whether there is a difference in the level of motor skills with regard to the level of nutrition. Based
on the obtained result, it could be confirmed hypothesis of this study that girls of normal body weight had a
significantly better motor skills of the students who were overweight or obese. For students who have a
problem with obesity must be developed intervention programs with a view to immediately engage in regular
physical exercise to reduce body weight.
