To examine the associations of self-perceived and objectively-measured physical fitness with psychological well-being and distress indicators in young pediatric cancer survivors.
A total of 116 participants (12.1 ± 3.3 years, 56.9% boys) from the iBoneFIT project participated in this cross-sectional study. Objectively-measured physical fitness (muscular fitness) was obtained by handgrip strength and standing long jump tests for the upper and lower body, respectively. Self-perceived physical fitness was obtained by the International Fitness Scale (IFIS). Positive and negative affect were assessed by the positive affect schedule for children (PANAS-C), happiness by Subjective Happiness Scale (SHS), optimism by Life Orientation Test-Revised (LOT-R), self-esteem by the Rosenberg Self-Esteem Scale (RSE), anxiety by State-Trait Anxiety Inventory for Children (STAIC-R), and depression by Children Depression Inventory (CDI). Multiple linear regressions adjusted by key covariates were performed to analyze associations.
No associations were found between objectively-measured muscular fitness and any of the psychological well-being and distress indicators (p > 0.05). Self-perceived overall fitness and flexibility were positively associated with positive affect (β ≥ 0.258, p < 0.05). Self-perceived cardiorespiratory fitness, speed/agility, and flexibility were negatively associated with depression (β ≥ -0.222, p < 0.05). Finally, self-perceived cardiorespiratory fitness was also negatively associated with anxiety and negative affect (β ≥ -0.264, p < 0.05).
Perceived physical fitness, but not objectively physical fitness, seems to be inversely related to psychological distress variables and to less extent positively related to psychological well-being. The findings from this study highlight the importance of promoting self-perceived fitness in the pediatric oncology population.
研究青少年癌症幸存者的自我感知和客观测量的体能与心理幸福感和困扰指标的相关性。
本横断面研究共纳入 iBoneFIT 项目的 116 名参与者（12.1±3.3 岁，56.9%为男性）。通过握力测试和立定跳远测试分别测量上肢和下肢的客观体能（肌肉力量）。自我感知的体能通过国际体能量表（IFIS）获得。通过儿童积极情绪量表（PANAS-C）评估积极情绪和消极情绪，通过主观幸福感量表（SHS）评估幸福感，通过修订后的生活取向测验（LOT-R）评估乐观程度，通过罗森伯格自尊量表（RSE）评估自尊，通过儿童状态-特质焦虑问卷（STAIC-R）评估焦虑，通过儿童抑郁量表（CDI）评估抑郁。采用多元线性回归分析，调整了关键协变量，以分析相关性。
客观测量的肌肉力量与任何心理幸福感和困扰指标均无相关性（p>0.05）。自我感知的整体体能和柔韧性与积极情绪呈正相关（β≥0.258，p<0.05）。自我感知的心肺功能、速度/敏捷性和柔韧性与抑郁呈负相关（β≥-0.222，p<0.05）。最后，自我感知的心肺功能也与焦虑和消极情绪呈负相关（β≥-0.264，p<0.05）。
与客观体能相比，自我感知的体能似乎与心理困扰变量呈负相关，与心理幸福感呈正相关，但程度较低。本研究的结果强调了在儿科肿瘤患者中促进自我感知体能的重要性。
