Abstract

Aims: The aims were (1) to analyse the cross-sectional and longitudinal associations between children's cardiorespiratory fitness (CRF) and health-related quality of life (HRQoL) and (2) to examine whether these associations were mediated by physical activity self-efficacy and physical activity enjoyment.

Methods: This study involved 383 children (10.0 ± 0.5 years) recruited from 20 primary schools in northwest England. Data were collected on two occasions 12 weeks apart. The number of laps completed in the 20-m Shuttle Run Test was used as the CRF indicator. HRQoL was assessed using the KIDSCREEN-10 questionnaire. Physical activity self-efficacy and enjoyment were assessed with the social-cognitive and Physical Activity Enjoyment Scale questionnaires, respectively. Linear mixed models with random intercepts (schools) assessed associations between CRF and HRQoL cross-sectionally, and longitudinally. Boot-strapped mediation procedures were performed, and indirect effects (IE) with 95% confidence intervals (CI) not including zero considered as statistically significant. Analyses were adjusted for sex, time of the year, socioeconomic status, waist-to-height ratio, maturation, and physical activity.

Results: CRF was cross-sectionally associated with HRQoL (β = 0.09, 95% CI = 0.02, 0.16; p = .015). In the longitudinal analysis, CRF at baseline was associated with HRQoL at 12 weeks after additionally controlling for baseline HRQoL (β = 0.08, 95% CI = 0.002; p = .15, p = .045). Cross-sectionally, physical activity self-efficacy and enjoyment acted individually as mediators in the relationship between CRF and HRQoL (IE = 0.069, 95% CI = 0.038; p = .105 and IE = 0.045, 95% CI = 0.016; p = .080, respectively). In the longitudinal analysis, physical activity self-efficacy showed a significant mediating effect (IE = 0.025, 95% CI = 0.004; p = .054).

Conclusion: Our findings highlight the influence of CRF on children's psychological correlates of physical activity and their overall HRQoL.

英格兰小学生心肺功能与健康相关生活质量之间的横向和纵向关系：体育锻炼心理相关因素的中介作用。

目的：旨在（1）分析儿童心肺功能（CRF）与健康相关生活质量（HRQoL）之间的横向和纵向联系；（2）研究这些联系是否受体育活动自我效能和体育活动乐趣的影响：这项研究涉及英格兰西北部 20 所小学的 383 名儿童（10.0 ± 0.5 岁）。数据收集分两次进行，每次间隔 12 周。在 20 米穿梭跑测试中完成的圈数被用作 CRF 指标。HRQoL 采用 KIDSCREEN-10 问卷进行评估。体育锻炼自我效能感和乐趣分别通过社会认知量表和体育锻炼乐趣量表问卷进行评估。随机截距线性混合模型（学校）评估了横向和纵向 CRF 与 HRQoL 之间的关系。采用引导式中介程序，并将 95% 置信区间（CI）不包含零的间接效应（IE）视为具有统计学意义。分析对性别、时间、社会经济地位、腰围与身高比、成熟度和体育锻炼进行了调整：CRF与HRQoL横向相关（β = 0.09，95% CI = 0.02，0.16；P = 0.015）。在纵向分析中，在对基线 HRQoL 进行额外控制后，基线 CRF 与 12 周时的 HRQoL 相关（β = 0.08，95% CI = 0.002；P = .15，P = .045）。在横向分析中，体育锻炼自我效能感和乐趣在 CRF 与 HRQoL 的关系中分别起着中介作用（IE = 0.069，95% CI = 0.038；p = .105 和 IE = 0.045，95% CI = 0.016；p = .080）。在纵向分析中，体育锻炼自我效能显示出显著的中介效应（IE = 0.025，95% CI = 0.004；P = .054）：我们的研究结果凸显了 CRF 对儿童体育锻炼心理相关因素及其整体 HRQoL 的影响。
