Office-Based Randomized Controlled Trial to Reduce Screen Time in Preschool Children
OBJECTIVE : To determine if an intervention for preschool-aged children in primary care is effective in reducing screen time , meals in front of the television , and BMI . METHODS : A r and omized controlled trial was conducted at a primary care pediatric group practice in Toronto , Canada . Three-year-old children and their parents were r and omly assigned to receive a short behavioral counseling intervention on strategies to decrease screen time .  The primary outcome 1 year later was parent reported screen time . Secondary outcomes included television in the child ’s bedroom , number of meals in front of the television , and BMI . RESULTS : In the intention-to-treat analysis at 1 year , there were no significant differences in mean total weekday minutes of screen time ( 60 , interquartile range [ IQR ] : 35–120 vs 65 , IQR : 35–120 ; P = .68 ) or mean total weekend day minutes of screen time ( 80 , IQR : 45–130 vs 90 , IQR : 60–120 ; P = .33 ) between the intervention and control group . Adjusting for baseline BMI , there was a reduction in the number of weekday meals in front of the television ( 1.6 ± 1.0 vs 1.9 ± 1.2 ; P = .03 ) but no differences in BMI or number of televisions in the bedroom . CONCLUSIONS : This pragmatic trial was not effective in reducing screen time or BMI but was effective in reducing meals in front of the screen . Short interventions focused solely on reducing screen time implemented in the primary care practice setting may not be effective in this age group
