Excessive screen time and diminished health-related quality of life (HRQoL) are greater problems for obese than nonobese adolescents, but no research has examined the relationship between these two variables. This study examined the association between screen time and HRQoL in overweight and obese adolescents.
A sample of 358 overweight and obese adolescents aged 14-18 years were assessed at baseline between 2005 and 2010 as part of the Canadian Healthy Eating, Aerobic and Resistance Training in Youth (HEARTY) trial. We used the Pediatric Quality of Life (PEDS-QL) and other self-report measures to assess HRQoL and screen time, defined as how long the 261 females and 97 males spent viewing TV, using the computer and playing video games.
After adjusting for socio-demographic variables, adiposity, physical activity and diet, screen time duration was associated with reduced overall HRQoL (adjusted r = -0.16, ß = -0.16, p = 0.009) and psychosocial HRQoL (adjusted r = -0.16, ß = -0.18, p = 0.004), but not physical HRQoL. No differences were found between males and females.
Screen time was associated with reduced overall and psychosocial HRQoL in overweight and obese adolescents. Future research should determine whether reducing screen time improves overall and psychosocial HRQoL in obese adolescents.
与非肥胖青少年相比，屏幕使用时间过长和健康相关生活质量（HRQoL）下降对肥胖青少年来说是更严重的问题，但尚无研究探讨这两个变量之间的关系。本研究调查了超重和肥胖青少年的屏幕使用时间与HRQoL之间的关联。
作为加拿大青少年健康饮食、有氧运动和抗阻训练（HEARTY）试验的一部分，在2005年至2010年期间对358名14至18岁的超重和肥胖青少年进行了基线评估。我们使用儿童生活质量量表（PEDS-QL）和其他自我报告测量方法来评估HRQoL和屏幕使用时间，屏幕使用时间定义为261名女性和97名男性花在看电视、使用电脑和玩电子游戏上的时长。
在对社会人口统计学变量、肥胖程度、身体活动和饮食进行调整后，屏幕使用时间与总体HRQoL降低（调整后r = -0.16，β = -0.16，p = 0.009）和心理社会HRQoL降低（调整后r = -0.16，β = -0.18，p = 0.004）相关，但与身体HRQoL无关。男性和女性之间未发现差异。
超重和肥胖青少年的屏幕使用时间与总体和心理社会HRQoL降低相关。未来的研究应确定减少屏幕使用时间是否能改善肥胖青少年的总体和心理社会HRQoL。
