To examine the associations between cardiorespiratory fitness, muscle strength, physical activity and waist circumference with self-reported health-related quality of life (HRQoL) in children.
We conducted a cross-sectional analysis that included 1129 school children aged 10 years from 57 schools in Sogn and Fjordane County, Norway. The HRQoL outcome was assessed by the self-reported KIDSCREEN-27 questionnaire, which covers five life domains. Independent variables were cardiorespiratory fitness assessed by the Andersen intermittent field running test, handgrip strength measured by a hand dynamometer, explosive strength in the lower body using a standing broad jump test, physical activity (counts per minute) using an accelerometer and abdominal adiposity measured by waist circumference. Statistical analyses were performed using linear mixed-effect models including school site as a random effect. Age and sex were entered as covariates.
Only cardiorespiratory fitness was positively associated with higher scores on all five KIDSCREEN-27 domains (P < 0.047 for all). Explosive strength in the lower body was positively associated with higher autonomy and parents scores (P = 0.018), while physical activity was positively associated with higher physical well-being scores (P = 0.008).
Improving cardiorespiratory fitness might be especially useful for improving HRQoL in children.
研究儿童心肺适能、肌肉力量、身体活动及腰围与自我报告的健康相关生活质量（HRQoL）之间的关联。
我们进行了一项横断面分析，纳入了挪威松恩-菲尤拉讷郡57所学校的1129名10岁学童。HRQoL结果通过自我报告的KIDSCREEN-27问卷进行评估，该问卷涵盖五个生活领域。自变量包括通过安徒生间歇场地跑步测试评估的心肺适能、用握力计测量的握力、用立定跳远测试评估的下肢爆发力、用加速度计测量的身体活动（每分钟计数）以及用腰围测量的腹部肥胖程度。使用包含学校地点作为随机效应的线性混合效应模型进行统计分析。年龄和性别作为协变量纳入。
仅心肺适能与KIDSCREEN-27所有五个领域的较高得分呈正相关（所有P<0.047）。下肢爆发力与较高的自主性和父母相关得分呈正相关（P=0.018），而身体活动与较高的身体健康得分呈正相关（P=0.008）。
改善心肺适能可能对提高儿童的HRQoL特别有用。
