Among children , these interventions demonstrated reduced screen time , increased physical activity , and improved diet- and weight-related outcomes .
CONTEXT Sedentary time spent with screen media is associated with obesity among children and adults .
Obesity has potentially serious health consequences , such as heart disease and diabetes .
This Community Guide systematic review examined the effectiveness and economic efficiency of behavioral interventions aim ed at reducing recreational ( i.e. , neither school- nor work-related ) sedentary screen time , as measured by screen time , physical activity , diet , and weight-related outcomes .
Household obesity prevention: Take Action--a group-randomized trial.
The purpose of the present study was to evaluate an intervention to prevent  weight gain among households ( HHs ) in the community . Ninety HHs were r and omized to intervention or control group for 1 year . Intervention consisted of six face-to-face group sessions , placement of a television ( TV ) locking device on all home TVs , and home-based intervention activities . Measures were collected in person at baseline and 1 year . Weight , height , eating behaviors , physical activity ( PA ) , and TV viewing were measured among HH members ages ≥ 12 years . Follow-up rate at 1 year was 96 % . No significant intervention effects were observed for change in HH BMI -z score . Intervention HHs significantly reduced TV viewing , snacks/sweets intake , and dollars per person spent eating out , and increased ( adults only ) PA and self-weighing frequency compared with control HHs . A 1 year obesity prevention intervention targeting entire HHs was effective in reducing TV viewing , snack/sweets intake and eating out purchases . Innovative methods are needed to strengthen the home food environment intervention component . Longer intervention duration s also need to be evaluated
