Abstract

Purpose

Previous studies have suggested that higher moderate-to-vigorous physical activity (MVPA) and lower sedentary behavior (SB) are linked to improved health-related quality of life (HRQoL) in children and adolescents. However, the link between light-intensity physical activity (LPA) and HRQoL remains unclear. This study examined the longitudinal association between LPA and HRQoL among students from fourth (aged 9–10) through eighth (aged 13–14) grade, considering the roles of MVPA and SB.

Methods

This five-year longitudinal study was conducted annually at private primary and secondary schools. Sixty-three primary school students (56 % girls) participated at baseline. LPA, MVPA, and SB were measured using a triaxial accelerometer, and HRQoL was assessed using the Japanese Pediatric Quality of Life Inventory. Data were analyzed using multilevel modeling with an exploratory approach.

Results

A negative association was observed between time-varying LPA and HRQoL scores, including the total scale (p = .040), psychosocial health summary (p = .032), and an emotional subscale (p = .013). A positive association was also observed between time-varying SB and the psychosocial health summary (p = .038) and its emotional subscale (p = .038). No association was found between MVPA and HRQoL. However, no association remained significant after false discovery rate (FDR) correction.

Conclusion

Our findings suggest that during the transition from primary to secondary school, students with decreased LPA and increased SB may experience improvements in HRQoL. As none of the associations remained significant after FDR correction, these findings should be interpreted with caution and considered hypothesis-generating.

9-14岁学生轻强度体育活动与健康相关生活质量的关系：一项5年纵向评估

先前的研究表明，较高的中高强度身体活动（MVPA）和较低的久坐行为（SB）与儿童和青少年健康相关生活质量（HRQoL）的改善有关。然而，低强度体力活动（LPA）与HRQoL之间的联系尚不清楚。本研究考察了四年级（9-10岁）至八年级（13-14岁）学生LPA与HRQoL之间的纵向关系，并考虑了MVPA和sba的作用。方法本研究每年在私立中小学进行为期五年的纵向研究。63名小学生（56%为女孩）在基线时参加了这项活动。使用三轴加速度计测量LPA、MVPA和SB，使用日本儿童生活质量量表评估HRQoL。采用探索性的多级建模方法对数据进行分析。结果随时间变化的LPA与HRQoL评分呈负相关，包括总量表（p = 0.040）、心理健康总结量表（p = 0.032）和情绪量表（p = 0.013）。随时间变化的SB与心理社会健康总结（p = 0.038）及其情绪分量表（p = 0.038）之间也存在正相关。MVPA与HRQoL之间无相关性。然而，在错误发现率（FDR）校正后，没有显著的关联。结论在小学到中学的过渡阶段，LPA下降和SB增加的学生的HRQoL可能有所改善。由于在FDR校正后，没有任何关联保持显著，因此这些发现应谨慎解释，并考虑为假设生成。

期刊介绍： The aims of Mental Health and Physical Activity will be: (1) to foster the inter-disciplinary development and understanding of the mental health and physical activity field; (2) to develop research designs and methods to advance our understanding; (3) to promote the publication of high quality research on the effects of physical activity (interventions and a single session) on a wide range of dimensions of mental health and psychological well-being (eg, depression, anxiety and stress responses, mood, cognitive functioning and neurological disorders, such as dementia, self-esteem and related constructs, psychological aspects of quality of life among people with physical and mental illness, sleep, addictive disorders, eating disorders), from both efficacy and effectiveness trials;
