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 .
Couch potatoes to jumping beans: A pilot study of the effect of active video games on physical activity in children
The primary objective of this pilot study was to evaluate the effect of active video games on  children 's physical activity levels . Twenty children ( mean ± SD age = 12 ± 1.5 years ; 40 % female ) were r and omised to receive either an active video game up grade package or to a control group ( no intervention ) . Effects on physical activity over the 12-week intervention period were measured using objective  ( Actigraph accelerometer ) and subjective ( Physical Activity Question naire for Children [ PAQ-C ] ) measures . An activity log was used to estimate time spent playing active and non-active video games . Children in the intervention group spent less mean time over the total 12-week intervention period playing all video games compared to those in the control group ( 54 versus 98 minutes/day [ difference = -44 minutes/day , 95 % CI [ -92 , 2 ] ] , p = 0.06 ) . Average time spent in all physical activities measured with an accelerometer was higher in the active video game intervention group compared to the control group ( difference at 6 weeks = 194 counts/min , p = 0.04 , and at 12 weeks = 48 counts/min , p = 0.06).This preliminary study suggests that playing active video games on a regular basis may have positive effects on children 's overall physical activity levels . Further research is needed to confirm if playing these games over a longer period of time could also have positive effects on children 's body weight and body mass index . Trial Registration
