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.

    • "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.

    • "Similar gender interaction has been found in a study of adolescents by Mar Bibiloni and colleagues (2012) who found that girls with lower parental educational levels reported higher frequency of sedentary behaviour (though the differences were statistically insignificant), while the same parental educational impact was not detected among boys. Finally, previous studies have found that physical activity levels are negatively associated with more frequent sedentary behaviour and media use (Koezuka, et al., 2006; Motl, et al., 2006; Raudsepp, et al., 2008; Gebremariam, et al., 2013). In a meta-analysis of the relationships between one type of sedentary behaviour, media use, body fatness and physical activity in children and youth, Marshall and colleagues (2004) found a small but negative relationship between TV viewing and physical activity.

    ABSTRACT: Introduction: Frequent physical activity has previously been found associated with numerous health benefits, yet it is unequally distributed across social strata, including in Slovenia. The aim of the present study was to examine the frequency of and inequalities in physical activity among Slovenian youth. Methods: A representative cross-sectional study of 907 men and women aged 16–27 years ( age = 21.90, s = 3.25, 48.3 % women) living in Slovenia was carried out examining the determinants of physical activity (measured with a single item on the frequency of physical activity in previous 7 days). Results: More than four out of ten young people (41.3 %) reported being vigorously physically active for at least 20 minutes daily only on two days or less in the previous week. Regression analysis indicated that eight predictor variables explained 4.2 % of the variance (Adjusted R2 = 3.4 %) in physical activity. Male gender was the only significant predictor of more frequent physical activity (β = 0.20, p < 0.001). In addition, interaction effect was detected with gender moderating the association between age and physical activity (β = -0.10, p < 0.05). Discussion and conclusion: Socioeconomic gradient in physical activity was not detected. Future studies should examine additional indicators of socioeconomic status and deprivation. The study results could provide a basis for programmes and interventions on physical activity that should target especially young women. Uvod: Raziskave kažejo, da ima redna gibalna aktivnost za zdravje številne pozitivne učinke, vendar je glede svoje pogostosti in stopnje neenakomerno porazdeljena med družbenimi sloji, kar velja tudi za Slovenijo. Namen pričujoče raziskave je bil preučiti pogostost in dejavnike gibalne aktivnosti med slovensko mladino. Metode: Izvedena je bila presečna anketna raziskava na reprezentativnem vzorcu 907 v Sloveniji stanujočih mladih, starih 16–27 let ( starost = 21,90, s = 3,25, 48,3 % žensk). Analizirani so bili dejavniki gibalne aktivnosti (pogoste gibalne aktivnosti v zadnjih sedmih dneh). Rezultati: Več kot štirje izmed desetih mladih (41,3 %) so poročali, da so bili v preteklem tednu le v dveh dnevih ali še redkeje intenzivno gibalno aktivni vsaj 20 minut dnevno. Regresijska analiza je pokazala, da je osem prediktorjev skupaj pojasnilo 4,2 % variance gibalne aktivnosti (prilagojena R2 = 3,4 %). Moški spol je bil edini statistično značilni napovedovalec pogostejše gibalne aktivnosti (β = 0,20, p < 0,001). Prav tako je bil zaznan interakcijski učinek spola, ki je moderiral odnos med starostjo in pogostostjo gibalne aktivnosti (β = 0,10, p < 0,05). Diskusija in zaključek: Vpliv socioekonomskega statusa na pogostost gibalne aktivnosti ni bil zaznan. V prihodnjih raziskavah bi bilo potrebno preučiti tudi druge kazalnike socioekonomskega položaja in deprivacije. Rezultati pričujoče raziskave bi lahko predstavljali podlago za programe in ukrepe na področju gibalne aktivnosti, ki bi morali biti usmerjeni predvsem na mlade ženske.
