背景一些观察性研究发现看电视与儿童和青少年肥胖之间存在关联，目的评估减少电视、录像带和电子游戏使用对肥胖、身体活动、设计随机对照学校-1996年9月至1997年4月进行的一项基于试验的研究。在198名三年级和四年级的学生中，有192名学生得到了父母的同意，（平均年龄，8.9岁）完成了研究。干预儿童在1所小学接受了18课，6个月的课堂课程，以减少电视，录像带，和视频游戏的使用。腰围和臀围，心肺功能;自我报告的媒体使用，身体活动和饮食行为;和父母报告的儿童和家庭行为。结果与对照组相比，干预组儿童的体重指数（BMI）相对下降，差异有统计学意义（P < 0. 05（干预组与对照组分别为18.38 ~ 18.67 kg/m2和18.10 ~ 18.81 kg/m2;校正差异-0.45 kg/m2 [95%置信区间{CI}，-0.73至-0.17]，P = .002），三头肌皮褶厚度（干预组与对照组的变化：分别为14.55至15.47 mm vs 13.97至16.46 mm;校正差异，-1.47 mm [95% CI，-2.41至-0.54]; P = .002），腰围（干预组与对照组的变化分别为：60.48至63.57 cm vs 59.51至64.73 cm;校正差异为-2.30 cm [95% CI，-3.27至-1.33]; P < .001），腰臀比（干预组与对照组变化：分别为0.83至0.83 vs 0.82至0.84;校正差异，-0.02 [95% CI，-0.03至-0.01]; P <0.001）。相对于对照组，干预组的变化伴随着儿童报告的电视观看和在电视机前吃饭的统计学显着下降。有没有组之间的变化在高脂肪食物的摄入量，中度到剧烈的体力活动，心肺fitness.Conclusions减少电视，录像带和视频游戏的使用可能是一个有前途的，以人口为基础的方法来预防儿童肥胖。
Context Some observational studies have found an association between television viewing and child and adolescent adiposity,Objective To assess the effects of reducing television, videotape, and video game use on changes in adiposity, physical activity, and dietary intake.Design Randomized controlled school-based trial conducted from September 1996 to April 1997.Setting Two sociodemographically and scholastically matched public elementary schools in San Jose, Calif.Participants Of 198 third- and fourth-grade students, who were given parental consent to participate, 192 students (mean age, 8.9 years) completed the study.Intervention Children in 1 elementary school received an 18-lesson, 6-month classroom curriculum to reduce television, videotape, and video game use.Main Outcome Measures Changes in measures of height, weight, triceps skinfold thickness, waist and hip circumferences, and cardiorespiratory fitness; self-reported media use, physical activity, and dietary behaviors; and parental report of child and family behaviors. The primary outcome measure was body mass index, calculated as weight in kilograms divided by the square of height in meters.Results Compared with controls, children in the intervention group had statistically significant relative decreases in body mass index (intervention vs control change: 18.38 to 18.67 kg/m(2) vs 18.10 to 18.81 kg/m(2), respectively; adjusted difference -0.45 kg/m2 [95% confidence interval {CI}, -0.73 to -0.17], P = .002), triceps skinfold thickness (intervention vs control change: 14.55 to 15.47 mm vs 13.97 to 16.46 mm, respectively; adjusted difference, -1.47 mm [95% CI, -2.41 to -0.54]; P = .002), waist circumference (intervention vs control change: 60.48 to 63.57 cm vs 59.51 to 64.73 cm, respectively; adjusted difference, -2.30 cm [95% CI, -3.27 to -1.33]; P < .001), and waist to-hip ratio (intervention vs control change: 0.83 to 0.83 vs 0.82 to 0.84, respectively; adjusted difference, -0.02 [95% CI, -0.03 to -0.01]; P < .001). Relative to controls, intervention group changes were accompanied by statistically significant decreases in children's reported television viewing and meals eaten in front of the television. There were no statistically significant differences between groups for changes in high-fat food intake, moderate-to-vigorous physical activity, and cardiorespiratory fitness.Conclusions Reducing television, videotape, and video game use may be a promising, population-based approach to prevent childhood obesity.
