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 .
The relative influence of demographic, individual, social, and environmental factors on physical activity among boys and girls
Background This study aim ed to evaluate the associations of selected demographic , individual , social , and environmental factors with moderate-to-vigorous physical activity ( MVPA ) in a sample of children and adolescents . Methods  MVPA  was assessed among youth ( n = 294 ) 10 - 17-years-old using the ActiGraph accelerometer . Youth completed measures of demographic and individual variables related to physical activity ( PA ) , perceived social support by parents and peers , and perceived neighborhood characteristics . Parents completed the long-form of the International Physical Activity Question naire . The Physical Activity and Media Inventory was used to measure the home environment and Geographical Information Systems software was used to measure the physical neighborhood environment . Bivariate correlations and hierarchical multiple regression were conducted stratified by gender . Results Boys participated in significantly more MVPA than girls . In hierarchical analyses , peer support , home PA equipment , and temperature were significantly associated with MVPA among boys whereas distance to the school they attended was associated with MVPA among girls . The final models accounted for 25 % and 15 % of the variance in MVPA among boys and girls , respectively . Conclusions Important differences exist among the individual , social , and environmental factors related to MVPA between boys and girls . Boys ' levels of activity appear to be influenced by factors closely linked to unstructured and social types of activities whereas girls ' activities relate to internal and external barriers as well as their proximity to their schools . The prospect i ve contribution of these important individual , social , and environmental factors to changes in MVPA among children and adolescents remains to be determined
