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 .
Decrease in television viewing predicts lower body mass index at 1-year follow-up in adolescents, but not adults.
OBJECTIVE To examine associations between television viewing , sugar-sweetened beverage consumption , eating out , physical activity , and body weight change over 1 year . DESIGN Secondary data analysis from r and omized intervention trial . SETTING Households in the community . PARTICIPANTS Adults ( n = 153 ) and adolescents ( n = 72 ) from the same households . INTERVENTION Households were r and omized to a home-based obesity prevention intervention or to a no-intervention control group for a 1-year period . MAIN OUTCOME MEASURES Self-reported television viewing ( TV ) hours , diet , and physical activity . Body mass index ( BMI ) computed from measured weight and height ( primary outcome measure ) . ANALYSIS Mixed-model regression . RESULTS Among adolescents , a significant prospect i ve association was observed between decreases in television viewing hours and lower BMI z score at 1-year follow-up ( decreased TV hours : BMI z score mean = 0.65 ; no change or increase TV hours : BMI z score = 0.92 ; P < .02 ) . No significant prospect i ve associations were observed among adults . CONCLUSIONS AND IMPLICATION S Reducing television viewing may be an effective strategy to prevent excess weight gain among adolescents
