We examined whether screen time was associated with cardiometabolic disease (CMD) risk factors in young adults. Ninety-five adults (19.9 ± 11.4 years) self-reported medical and health behavior history, screen time (television viewing, video games and computer games), and dietary intake. Waist circumference, blood pressure, fasting glucose and lipid levels, cardiorespiratory fitness (VO₂peak), and body composition were measured. Total sedentary behavior and moderate-to-vigorous physical activity (MVPA) were measured by accelerometer. On average, leisure screen time (2.0 ± 1.6 h day⁻¹) accounted for 24% of total sedentary time (8.4 ± 1.5 h day⁻¹). After adjustment for demographics, smoking, sleep duration, total energy intake, total sedentary time and MVPA, a 1-standard deviation increase in leisure screen time was associated with a 26% higher BMI, 29% higher waist circumference, 25% higher fat mass, 23% higher triglyceride, and 24% lower VO₂peak (p < 0.05). Our findings suggest that screen time may contribute to the risk of obesity and CMD in young adults.

大学生休闲屏幕时间与心脏代谢生物标志物的关联。

我们检查了屏幕时间是否与年轻人的心脏代谢疾病 (CMD) 风险因素相关。95 名成年人（19.9 ± 11.4 岁）自我报告的医疗和健康行为史、屏幕时间（看电视、视频游戏和电脑游戏）和饮食摄入量。测量了腰围、血压、空腹血糖和血脂水平、心肺健康（VO ₂峰值）和身体成分。总久坐行为和中度到剧烈的体力活动 (MVPA) 由加速度计测量。平均而言，休闲屏幕时间（2.0 ± 1.6 h day ^-1）占总久坐时间（8.4 ± 1.5 h day ^-1）的 24%）。在调整人口统计、吸烟、睡眠时间、总能量摄入、总久坐时间和 MVPA 后，休闲屏幕时间增加 1 个标准差与 BMI 增加 26%、腰围增加 29%、脂肪量增加 25% 相关、高 23% 的甘油三酯和低 24% 的 VO ₂峰值 ( p  < 0.05)。我们的研究结果表明，屏幕时间可能会增加年轻人患肥胖症和 CMD 的风险。
