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 .
A pilot of a video game (DDR) to promote physical activity and decrease sedentary screen time.
OBJECTIVE We examined the feasibility of Dance Dance Revolution ( DDR ) , a dance video game , in participants ' homes , to increase physical activity ( PA ) and to decrease sedentary screen time ( SST ) . METHODS AND PROCEDURES Sixty children ( 7.5 + /- 0.5 years ) were r and omized in a 2:1 ratio to DDR or to wait-list control ( 10-week delay ) . DDR use was logged , PA was measured objective ly by accelerometry . SST was self-reported at weeks 0 and 10 . At week 28 , after both groups had access to DDR , accelerometry and SST were repeated . RESULTS Mean use of DDR was 89 + /- 82 ( range 0 - 660 min ) min per week ( mpw ) . The DDR group showed increased vigorous PA and a reduction in light PA ; the control group showed no increase in moderate and /or vigorous PA ( MVPA ) although they also had a reduction in light PA . Differences between the groups were not observed . The DDR group also reported a decrease in SST of -1.2 + /- 3.7 h per week ( hpw ) ( P < 0.05 ) , whereas the controls reported an increase of + 3.0 + /- 7.7 hpw ( nonsignificant ) . The difference in SST between the groups was significant , with less SST in the DDR group . Between weeks 10 and 28 , numeric reductions in SST were reported in both groups . In the DDR group , SST at week 28 ( 8.8 + /- 6.0 hpw ) was lower than baseline ( 10.5 + /- 5.5 hpw ; P < 0.03 ) . DISCUSSION This pilot study suggests that DDR reduces SST and may facilitate slight increases in vigorous PA . Further study is needed to better characterize children and context s in which DDR may promote a healthy lifestyle
