This study investigates the association between adherence to the 24-h movement guidelines, which include physical activity (PA), screen time (ST), and sleep duration (SD), and health-related quality of life (HRQoL) in a representative sample of Spanish children and adolescents aged 8-14 years.
Data were obtained from the Spanish National Health Survey (2017), a representative cross-sectional survey. The survey employed a three-stage sampling process and included 2711 participants aged 8-14 years after exclusions for missing data. HRQoL was assessed using the modified KIDSCREEN-10 (proxy version). PA, ST, and SD were self-reported by parents and categorized based on international guidelines. Covariates such as age, sex, socioeconomic status, body mass index (BMI), and diet quality were also considered. Robust linear regression models were used to examine associations between the number of guidelines met and HRQoL, adjusting for potential confounders.
Overall, a positive dose-response association was observed, with greater compliance with the 24-h movement guidelines linked to higher HRQoL. After adjusting for potential covariates, significant differences in HRQoL were identified on the basis of adherence to the guidelines. Compared with those who complied with one, two, or all three guidelines, participants who adhered to none of the guidelines presented a lower HRQoL. However, significant differences were found only between those who adhered to any of the guidelines and those who followed two (p = 0.003), or all the three (p < 0.001) guidelines.
A combination of optimal levels of PA, ST and SD could play a crucial role in enhancing HRQoL among children and adolescents.
本研究调查了西班牙8至14岁儿童和青少年的代表性样本中，遵守24小时运动指南（包括身体活动（PA）、屏幕时间（ST）和睡眠时间（SD））与健康相关生活质量（HRQoL）之间的关联。
数据来自西班牙国家健康调查（2017年），这是一项具有代表性的横断面调查。该调查采用三阶段抽样过程，排除缺失数据后，纳入了2711名8至14岁的参与者。使用改良的儿童生活质量量表-10（代理版本）评估HRQoL。PA、ST和SD由家长自我报告，并根据国际指南进行分类。还考虑了年龄、性别、社会经济地位、体重指数（BMI）和饮食质量等协变量。使用稳健线性回归模型来检验符合指南的数量与HRQoL之间的关联，并对潜在混杂因素进行调整。
总体而言，观察到了正剂量反应关联，即更好地遵守24小时运动指南与更高的HRQoL相关。在调整潜在协变量后，根据对指南的遵守情况确定了HRQoL的显著差异。与遵守一项、两项或所有三项指南的参与者相比，一项指南都不遵守的参与者的HRQoL较低。然而，仅在遵守任何一项指南的参与者与遵守两项（p = 0.003）或所有三项（p < 0.001）指南的参与者之间发现了显著差异。
PA、ST和SD的最佳水平组合可能在提高儿童和青少年的HRQoL方面发挥关键作用。
