体力活动不足（PA）和过度静止行为（SB）是导致儿童肥胖的原因，尽管这些行为在该人群中的前因和后果相对未知。这项试点研究调查了 17 名超重/肥胖青少年的 PA 和 SB 周围的情绪、饮食失控 (LOCE)、暴饮暴食和饥饿。参与者佩戴加速度计完成了为期 14 天的生态瞬时评估 (EMA)。在瞬时水平上，较高的负面情绪和较低的正面情绪预示着 EMA 提示后 SB 会增加，PA 会减少；较高的积极影响预测 PA 增加。较高的 LOCE 预测 SB 增加和 PA 减少，而 PA 增加和 SB 减少则预测 LOCE 和暴饮暴食的短期增加。在个人层面上，较高的 SB 和较低的 PA 与较低的积极情绪和较高的消极情绪、LOCE、暴饮暴食和饥饿有关。研究结果表明，情感是 PA/SB 的相关前因和后果，饮食失调可能会严重影响 PA/SB。
Insufficient physical activity (PA) and excessive stationary behavior (SB) are contributors to pediatric obesity, though antecedents and consequences of these behaviors in this population are relatively unknown. This pilot study examined affect, loss of control eating (LOCE), overeating, and hunger surrounding PA and SB in 17 youth with overweight/obesity. Participants completed a 14-day ecological momentary assessment (EMA) wearing accelerometers. At the momentary level, higher negative affect and lower positive affect predicted SB increases and PA decreases following EMA prompts; higher positive affect predicted PA increases. Higher LOCE predicted SB increases and PA decreases, while increases in PA and decreases in SB predicted short-term increases in LOCE and overeating. At the individual level, higher SB and lower PA were related to lower positive affect and higher negative affect, LOCE, overeating, and hunger. Findings suggest affect is a relevant antecedent and consequence of PA/SB, and dysregulated eating may acutely impact PA/SB.
