Health-related quality of life (HRQoL) represents the perception of each person about different aspects of their lives in the health context (physical, psychological, social environment and interpersonal relationships). Among adolescents, HRQoL can change considering habits adopted in this phase of life. This study analyzed the association between time used on different sedentary behaviors (SB) and HRQoL in adolescents. This is a cross-sectional epidemiological study with adolescents between 10 - 15 years of age. The SB was measured using a questionnaire (n = 1,455 adolescents) and accelerometer (n = 844 adolescents), and HRQoL using KIDSCREEN - 27. Time on videogames/cell phones/tablets was inversely associated with overall HRQoL (β = -0.021; 95%CI: -0.026; -0.006), psychological well-being (β = -0.030; 95%CI: -0.050; -0.010), peer social support (β = -0.041; 95%CI: -0.066; -0.016) and school environment (β = -0.033; 95%CI: -0.056; -0.010) scores. Screen time was inversely associated with the school environment score (β = -0.011; 95%CI: -0.020; -0.003). Computer time was positively associated with the psychological well-being (β = 0.025; 95%CI: 0.006; 0.043) and peer social support scores (β = 0.029; 95%CI: 0.004; 0.053). It concluded that adolescents with more screen time had lower HRQoL. However, theses associations varied with the type and method of SB measurement and the HRQoL dimension.
健康相关生活质量（HRQoL）代表了每个人在健康背景下对生活不同方面的感知（身体、心理、社会环境和人际关系）。在青少年中，由于在这一生命阶段所采用的习惯，HRQoL 可能会发生变化。本研究分析了青少年不同久坐行为（SB）时间与 HRQoL 之间的关联。这是一项横断面流行病学研究，对象为 10-15 岁的青少年。使用问卷（n=1455 名青少年）和加速度计（n=844 名青少年）测量 SB，使用 KIDSCREEN-27 评估 HRQoL。玩电子游戏/手机/平板电脑的时间与整体 HRQoL（β=-0.021；95%CI：-0.026；-0.006）、心理幸福感（β=-0.030；95%CI：-0.050；-0.010）、同伴社会支持（β=-0.041；95%CI：-0.066；-0.016）和学校环境（β=-0.033；95%CI：-0.056；-0.010）评分呈负相关。屏幕时间与学校环境评分呈负相关（β=-0.011；95%CI：-0.020；-0.003）。使用电脑时间与心理幸福感（β=0.025；95%CI：0.006；0.043）和同伴社会支持评分（β=0.029；95%CI：0.004；0.053）呈正相关。研究结果表明，屏幕时间较多的青少年 HRQoL 较低。然而，这些关联因 SB 测量类型和方法以及 HRQoL 维度而异。
