The 24-Hour Movement Guidelines for adolescents recommend ≥60 min/day of moderate-to-vigorous physical activity (PA), ≤ 2 h/day of screen time, and 8-10 h/day of sleep. Since little information is available on the 24-Hour Movement Guidelines in Spanish adolescents, this study aims to estimate the proportion of Spanish adolescents meeting individual and combinations of these 24-Hour Movement Guidelines. Moreover, another aim of this study is to examine gender differences in compliance with 24-Hour Movement Guidelines.
A final sample of 1465 Spanish adolescents (44.50% girls; 13.08 ± 0.86) participated in this cross-sectional study. The 24-Hour Movement Guidelines were measured during weekdays and the weekend days by self-reported questionnaires.
Although most adolescents met sleep duration guidelines (81.3%), only 38% and 15.8% met physical activity and screen time guidelines, respectively. Only 5.4% of these adolescents met all three 24-Hour Movement Guidelines, whereas 10.2% of this sample did not meet any of these guidelines. Although boys reported greater compliance with physical activity recommendations and girls with screen time recommendations, no significant gender differences were found in the compliance of all three 24-Hour Movement Guidelines.
Given that 94.4% of Spanish adolescents did not meet 24-Hour Movement Guidelines, promoting all these three movement behaviours in both boys and girls is an urgent public health priority.
青少年24小时运动指南建议每天进行≥60分钟的中等至剧烈身体活动（PA），每天屏幕时间≤2小时，以及每天睡眠8 - 10小时。由于关于西班牙青少年24小时运动指南的信息较少，本研究旨在估计符合这些24小时运动指南单项及综合标准的西班牙青少年比例。此外，本研究的另一个目的是研究在遵守24小时运动指南方面的性别差异。
1465名西班牙青少年（44.50%为女孩；年龄13.08 ± 0.86岁）的最终样本参与了这项横断面研究。通过自我报告问卷在工作日和周末测量24小时运动指南的各项指标。
尽管大多数青少年符合睡眠时间指南（81.3%），但分别只有38%和15.8%的青少年符合身体活动和屏幕时间指南。这些青少年中只有5.4%符合所有三项24小时运动指南，而该样本中有10.2%的青少年一项指南都未符合。尽管男孩报告在遵守身体活动建议方面做得更好，女孩在遵守屏幕时间建议方面做得更好，但在遵守所有三项24小时运动指南方面未发现显著的性别差异。
鉴于94.4%的西班牙青少年未达到24小时运动指南标准，在男孩和女孩中推广这三种运动行为是当务之急的公共卫生重点。
