BACKGROUND
There is an epidemic of obesity in children and adolescents. Research into the self-regulatory factors that drive eating behavior is of critical importance. Food craving contributes to overeating and difficulty with weight loss and is strongly correlated with self-regulation. High-frequency heart rate variability (HF HRV) reflects parasympathetic activity and is positively associated with self-regulation. Few studies of HF HRV and food craving have been conducted in adolescents. The current study examined the association between HF HRV and food craving in a large-scale sample of healthy adolescents.
METHOD
Electrocardiogram (ECG) was recorded in 134 healthy adolescents aged 10-17 during a 7-min resting state. Participants also completed the Food Craving Questionnaire-Trait (FCQ-T). The relative power of HF HRV was calculated. Association between HF HRV and food craving was examined in the context of sex and age. Next, the relative significance of all food craving subscales was considered in relation to HF HRV.
RESULTS
HF HRV was inversely correlated with food craving, taking into account sex and age. Considering all the subscales of FCQ-T in relation to HF HRV, the "lack of control over eating" subscale accounted for the most significant variance.
CONCLUSION
This was the first study to evaluate resting HRV and eating behaviors in a large-scale adolescent sample. HF HRV was negatively associated with food craving, with lower HF HRV correlating with higher food craving, especially in the context of diminished control over eating. HF HRV could be a potential biomarker for food craving and food-related self-regulation capacity, and therefore may aid weight management interventions.
背景
儿童和青少年肥胖症呈流行趋势。研究驱动进食行为的自我调节因素至关重要。食物渴望会导致暴饮暴食和减肥困难，并且与自我调节密切相关。高频心率变异性（HF HRV）反映副交感神经活动，与自我调节呈正相关。很少有研究探讨青少年的 HF HRV 和食物渴望之间的关系。本研究在一个大规模的健康青少年样本中，考察了 HF HRV 和食物渴望之间的关系。
方法
在 7 分钟的静息状态下，对 134 名 10-17 岁的健康青少年进行心电图（ECG）记录。参与者还完成了食物渴望问卷特质（FCQ-T）。计算 HF HRV 的相对功率。在考虑性别和年龄的情况下，考察 HF HRV 与食物渴望之间的关系。接下来，考虑与 HF HRV 相关的所有食物渴望分量表的相对重要性。
结果
HF HRV 与食物渴望呈负相关，同时考虑到性别和年龄。考虑到 FCQ-T 的所有分量表与 HF HRV 的关系，“对进食缺乏控制”分量表解释了最大的差异。
结论
这是第一项在大规模青少年样本中评估静息 HRV 和进食行为的研究。HF HRV 与食物渴望呈负相关，HF HRV 越低，食物渴望越高，尤其是在控制进食能力下降的情况下。HF HRV 可能是食物渴望和与食物相关的自我调节能力的潜在生物标志物，因此可能有助于体重管理干预。
