There is a large body of evidence from all study design s which suggests that decreasing any type of sedentary time is associated with lower health risk in youth aged 5 - 17 years .
In particular , the evidence suggests that daily TV viewing in excess of 2 hours is associated with reduced physical and psychosocial health , and that lowering sedentary time leads to reductions in BMI
Accumulating evidence suggests that , independent of physical activity levels , sedentary behaviours are associated with increased risk of cardio-metabolic disease , all-cause mortality , and a variety of physiological and psychological problems .
Therefore , the purpose of this systematic review is to determine the relationship between sedentary behaviour and health indicators in school-aged children and youth aged 5 - 17 years .
Compliance with the Australian national physical activity guidelines for children: relationship to overweight status.
Childhood obesity incidence has increased substantially and it has been argued that decreasing physical activity levels , coinciding with an increase in sedentary behaviours , are responsible . Australian guidelines were published in 2004 , recommending that children participate in a minimum of 60 min of physical activity daily and spend no more than 2h a day using electronic media for entertainment . We aim ed to compare compliance with these guidelines amongst children of differing weight status . The Childhood Injury Prevention Study ( CHIPS ) collected data from a r and omly selected sample of Brisbane primary and preschool children aged 5 - 12 years . The following data were available for 518 participants : age , gender , measured height and weight and estimated time per week from a parent-completed 7 days diary in physical activity out of school and sedentary leisure activities including television viewing and computer use . Using age st and ardised body mass index estimates , approximately 20 % of the cohort were overweight . Non-compliance with guidelines was 14.7 % for out of school physical activity participation , and 30.9 % for excess electronic media entertainment use . There was a 63 % increase in the odds of overweight status amongst children who were non-compliant with the electronic entertainment recommendations than those who were compliant ( adjusted odds ratio=1.63 ; 95 % CI=1.05 - 2.54 ) . Female gender and school level socioeconomic category were also independently associated with overweight status . Non-compliance with the minimal physical activity guideline increased the odds of being overweight by 28 % , however this difference was not statistically significant . One in seven children from the Greater Brisbane area are at risk for being insufficiently active whilst a third overuse electronic media . Given that overuse of electronic entertainment was positively associated with childhood obesity , these children should be the target of public health campaigns to promote alternative leisure time activities
