Interventions that reduced sedentary time by using TV limiting devices were shown to be effective for children but the results were limited for adults .
Overall , large exercise equipment ( ie .
treadmills ) , and prominent exergaming material s ( exergaming bike , dance mats ) were found to be more effective than smaller devices .
Observational studies revealed that location and quantity of televisions correlated with SD behavior with the latter having a greater effect on girls .
This was similarly found for the quantity of PA equipment which also correlated with behavior in females .
Review s of neighborhood ( macro ) environment characteristics such as the presence of sidewalks and esthetics have shown significant correlations with  resident physical activity ( PA ) and sedentary ( SD ) behavior .
Currently , no comprehensive review has appraised and collected available evidence on the home ( micro ) physical environment .
The purpose of this review was to examine how the home physical environment relates to adult and child PA and SD behaviors .
Impact of an Active Video Game on Healthy Children’s Physical Activity
OBJECTIVE : This naturalistic study tests whether children receiving a new ( to them ) active video game  spontaneously engage in more physical activity than those receiving an inactive video game  , and whether the effect would be greater among children in unsafe neighborhoods , who might not be allowed to play outside . METHODS : Participants were children 9 to 12 years of age , with a BMI > 50th percentile , but < 99th percentile ; none of these children a medical condition that would preclude physical activity or playing video games . A r and omized clinical trial assigned children to receiving 2 active or 2 inactive video games , the peripherals necessary to run the games , and a Wii console .  Physical activity was monitored by using accelerometers for 5 weeks over the course of a 13-week experiment . Neighborhood safety was assessed with a 12 item vali date d question naire . RESULTS : There was no evidence that children receiving the active video games were more active in general , or at anytime , than children receiving the inactive video games . The outcomes were not moderated by parent perceived neighborhood safety , child BMI z score , or other demographic characteristics . CONCLUSIONS : These results provide no reason to believe that simply acquiring an active video game under naturalistic circumstances provides a public health benefit to children
