在年轻人中，较高的心率(HR)和较低的心率变异性(HRV)是自然环境中出现失控(LOC)进食发作的先兆。然而，在实验室环境下检验餐前心率和心率变异性是否与更多的低碳水化合物摄入有关的数据有限。因此，我们研究了餐前心率、基于频率和时间的餐前心率变异性指标、感知的LOC进食量以及为模拟LOC进食事件而设计的进餐期间的能量摄入之间的时间关系。209名受试者(女性54.5%，年龄12.58±2.72岁，体重指数0.52±1.02BMIz)中，有19人在前一个月进食过LOC。实验室餐期间的LOC摄入量与餐前心率无显著相关(p=0.37)，但与餐前心率变异性呈正相关(PS=0.02-0.04)。这一发现是由最近吃过LOC的年轻人推动的，因为当只在没有最近报告吃LOC的参与者中进行分析时，这些关联并不显著(p=0.15-0.99)。餐前心率和心率变异性与总能量摄入量无显著相关性(PS=0.27~0.81)。还需要进一步的研究来确定早期儿童进食LOC之前是否有健康的餐前应激反应。纵向研究可能有助于澄清这种模式是否会随着时间的推移而在反复出现LOC进食发作的年轻人中变得不那么起作用。
Among youth, greater heart rate (HR) and lesser HR variability (HRV) are precursors to loss-of-control (LOC) eating episodes in the natural environment. However, there are limited data examining whether pre-meal HR and HRV are associated with greater LOC-eating in the laboratory setting. We therefore examined temporal relationships between pre-meal HR, frequency- and time-based metrics of pre-meal HRV, perceived LOC-eating, and energy intake during a meal designed to simulate a LOC-eating episode. Among 209 participants (54.5% female, 12.58 ± 2.72 years, 0.52 ± 1.02 BMIz), 19 reported LOC-eating in the prior month. Perceived LOC-eating during the laboratory meal was not significantly linked to pre-meal HR (p = 0.37), but was positively related to pre-meal HRV (ps = 0.02–0.04). This finding was driven by youth with recent LOC-eating, as these associations were not significant when analyses were run only among participants without recent reported LOC-eating (p = 0.15–0.99). Pre-meal HR and HRV were not significantly related to total energy intake (ps = 0.27–0.81). Additional research is required to determine whether early-stage pediatric LOC-eating is preceded by a healthy pre-meal stress response. Longitudinal studies could help clarify whether this pattern becomes less functional over time among youth who develop recurrent LOC-eating episodes.
