Among school-aged youth, we sought to identify characteristics associated with (1) exceeding screen time recommendations (ie, television/videos/video games more than 2 hours/weekday), and (2) exceeding screen time recommendations, the presence of a television in the bedroom, and obesity.
Using 2007 National Survey of Children's Health data, we used multivariable logistic regression to identify sociodemographic and behavioral characteristics associated with excessive screen time among 6 to 11- and 12 to 17-year-olds on a typical weekday. For 12 to 17-year-olds only, we used logistic regression to examine the odds of obesity using the same variables as above, with the addition of screen time.
Overall, 20.8% of 6 to 11-year-olds and 26.1% of 12 to 17-year-olds had excessive screen time. For both age groups, having a bedroom TV was significantly associated with excessive screen time. For the older age group, the dual scenario of excessive screen time with a bedroom TV had the strongest association with obesity (OR = 2.5, 95% CI 1.9, 3.2).
Given the similar risk factors for excess screen time and having a TV in the bedroom, a public health challenge exists to design interventions to reduce screen time among school-aged youth.
"This study found that youth with ADD/ADHD with a bedroom TV engaged in almost a half hour more screen time daily than youth without a bedroom TV. These findings are similar to associations observed among U.S. youth generally (Wethington et al., 2013; Ramirez et al., "
[Show abstract][Hide abstract] ABSTRACT: Objective
A TV in the bedroom has been associated with screen time in youth. Youth with attention deficit hyperactivity disorder (ADD/ADHD) have higher rates of screen time, but associations with bedroom TVs are unknown in this population. We examined the association of having a bedroom TV with screen time among youth with ADD/ADHD.
Data were from the 2007 National Survey of Children's Health. Youth 6–17 years whose parent/guardian reported a physician's diagnosis of ADD/ADHD (n = 7024) were included in the analysis. Parents/guardians reported the presence of a bedroom TV and average weekday TV screen time. Multivariate linear and logistic regression models assessed the effects of a bedroom on screen time.
Youth with ADD/ADHD engaged in screen time with an average of 149.1 min/weekday and 59% had a TV in their bedroom. Adjusting for child and family characteristics, having a TV in the bedroom was associated with 25 minute higher daily screen time (95% CI: 12.8–37.4 min/day). A bedroom TV was associated with 32% higher odds of engaging in screen time for over 2 h/day (OR = 1.3; 95% CI: 1.0–1.7).
Future research should explore whether removing TVs from bedrooms reduces screen time among youth with ADD/ADHD.
"poverty ) (Bambra et al., 2013), the result of a lack of access to nutrient rich foods (Budzynska et al., 2013)), as well as behavioural [e.g. lack of physical activity (Heinonen et al., 2013), screen time (Wethington et al., 2013) and dietary (Rolls, 2012)]. The prevalence of obesity and potential severity of its consequences have created the impetus to identify an immediate and simple solution to this complex problem. "

There are limited data available on the longitudinal relationship between candy consumption by children on weight and other cardiovascular risk factors (CVRF) in young adults. The present study investigated whether candy consumption in children was predictive of weight and CVRF in young adults. MethodsA longitudinal sample of children 10 years (n = 355; 61% females; 71% European-Americans, 29% African-Americans) who participated in cross-sectional surveys from 1973 to 1984 (baseline) and in one of two surveys (follow-ups) as young adults [19–38 years; mean (SD) = 23.6 (2.6) years] in Bogalusa, LA, were studied. Dietary data were collected using 24-h dietary recalls at baseline and at one follow-up survey; a food frequency questionnaire was used in the other follow-up survey. Candy consumers were those consuming any amount of candy. Candy consumption was calculated (g day–1) from baseline 24-h dietary recalls, and was used as a covariate in the adjusted linear mixed models. Dependent variables included body mass index (BMI) and CVRF measured in young adults. ResultsAt baseline, 92% of children reported consuming candy [46 (45) g day–1]; the percentage decreased to 67% [20 (30) g day–1] at follow-up. No longitudinal relationship was shown between baseline candy consumption and BMI or CVRF in young adults, suggesting that candy consumption was not predictive of health risks later in life. Conclusions
The consumption of nutrient rich foods consistent with dietary recommendations is important, although modest amounts of candy can be added to the diet without potential adverse long-term consequences to weight or CVRF. Additional studies are needed to confirm these results.
