身体活动与日常生活中情感幸福感之间的关系：一项基于个体参与者数据的荟萃分析 An individual participant data meta-analysis of how physical activity relates to affective well-being in daily life ——《自然-人类行为》第10卷第7期，2026年7月—— <Nature / Human Behaviour>, Volume 10, Issue 7, July 2026 【摘要】缺乏身体活动是一个紧迫的社会问题。要充分发挥身体活动（PA）作为关键健康资源的潜力，必须理解参与身体活动的机制。实验室研究和干预研究已证实运动与情感幸福感（AWB）相关，并提示AWB可能影响身体活动行为。数字化技术使得研究日常生活中的身体活动与AWB之间的关系成为可能，但既往单项研究的结论尚不明确。本研究汇总了截至2023年12月的67个数据集（占符合条件记录的55.2%），涵盖了321,345次基于智能手机的AWB评分和近100万小时由加速度计测量的身体活动数据（参与者总数N=8,223），旨在阐明身体活动与AWB之间关联的性质与程度。基于个体参与者数据的一阶段和两阶段荟萃分析显示，日常生活中的瞬时AWB与先前的身体活动（个体内部：r=0.05，99.2%置信区间[CI] 0.03–0.06；个体之间：r=0.08，99.2% CI 0.04–0.12）及随后的身体活动（个体内部：r=0.04，99.2% CI 0.03–0.05；个体之间：r=0.08，99.2% CI 0.04–0.13）均存在关联。在个体内部，身体活动与精力充沛的唤醒状态（energetic arousal）、积极情感状态及情感效价（valence）呈正相关，而与平静感呈负相关。其实际效应量与其他日常生活活动相当，其中精力充沛的唤醒状态与身体活动的关联最为显著。个体间关联存在的显著异质性，可部分由社会人口学调节变量来解释。在个体之间，身体活动与积极情感状态相关。这些结果证实了身体活动与情感幸福感之间的关系在日常生活中的重要意义。它们有助于健康行为模型的修订与发展，并为探究身体活动（PA）与情感幸福感（AWB）之间关联背后的行为、生理及神经机制提供了一个切入点。 [Abstract] Physical inactivity constitutes a pressing societal problem. To realize physical activity’s (PA) potential as a key health resource, mechanisms of PA engagement need to be understood. Laboratory and interventional studies documented that exercise relates to affective well-being (AWB) and suggested that AWB may shape PA behaviour. Digitalization enabled the investigation of how PA relates to AWB in everyday life, but findings from individual studies are ambiguous. Here we compiled 67 datasets (55.2% of eligible records) including 321,345 smartphone-based AWB ratings and nearly 1,000,000 h of accelerometer-measured PA (N = 8,223 participants) until December 2023 to clarify the nature and extent of PA–AWB associations. One- and two-stage individual participant data meta-analyses reveal that momentary AWB is associated with both prior (within, r = 0.05, 99.2% confidence intervals (CI) 0.03 to 0.06; between, r = 0.08, 99.2% CI 0.04 to 0.12) and subsequent (within, r = 0.04, 99.2% CI 0.03 to 0.05; between, r = 0.08, 99.2% CI 0.04 to 0.13) short-term PA in everyday life. Within persons, PA displays a positive association with energetic arousal, positive affective states and valence, yet a negative relation to calmness. The practical effect sizes are comparable to other daily life activities, with energetic arousal evincing the strongest relation to PA. Considerable heterogeneity in associations across individuals can be partially explained by sociodemographic moderators. Between participants, PA relates to positive affective states. The results document the critical relevance of PA–AWB relations in everyday life. They can contribute to the revision and development of health behaviour models and establish a starting point to approach behavioural, physiological and neuronal mechanisms underlying PA–AWB associations. 论文原文：Johanna Rehder, Irina Timm, Gesa Berretz, et al.
