Abstract

BACKGROUND

Eating alone has been significantly associated with psychological distress. However, there is no research that evaluates the effects or relation of eating together online to autonomic nervous system functions.

METHODS

This is a randomized, open-label, controlled, pilot study conducted among healthy volunteers. Participants were randomized into either an eating together online group or an eating-alone group. The effect of eating together on autonomic nervous functions was evaluated and compared with that of the control (eating alone). The primary endpoint was the change in the standard deviation of the normal-to-normal interval (SDNN) scores among heart rate variabilities (HRV) before and after eating. Physiological synchrony was investigated based on changes in the SDNN scores.

RESULTS

A total of 31 women and 25 men (mean age, 36.6 [SD = 9.9] years) were included in the study. In the comparison between the aforementioned groups, two-way analysis of variance revealed interactions between time and group on SDNN scores. SDNN scores in the eating together online group increased in the first and second halves of eating time (F[1,216], P < 0.001 and F[1,216], P = 0.022). Moreover, high correlations were observed in the changes in each pair before and during the first half of eating time as well as before and during the second half of eating time (r = 0.642, P = 0.013 and r = 0.579, P = 0.030). These were statistically significantly higher than those in the eating-alone group (P = 0.005 and P = 0.040).

CONCLUSIONS

The experience of eating together online increased HRV during eating. Variations in pairs were correlated and may have induced physiological synchrony.

摘要

背景

独自用餐与心理困扰显著相关。然而，尚无研究评估在线一起用餐对自主神经系统功能的影响或关系。

方法

这是一项在健康志愿者中进行的随机、开放标签、对照的试点研究。参与者被随机分为在线一起用餐组或独自用餐组。评估一起用餐对自主神经功能的影响，并与对照组（独自用餐）进行比较。主要终点是进食前后心率变异性（HRV）中正常到正常间隔（SDNN）分数的变化。基于SDNN分数的变化研究生理同步性。

结果

共有31名女性和25名男性（平均年龄36.6[标准差=9.9]岁）纳入研究。在上述组之间的比较中，双向方差分析显示时间和组在SDNN分数上存在交互作用。在线一起用餐组的SDNN分数在进食时间的前半段和后半段均增加（F[1,216]，P<0.001和F[1,216]，P=0.022）。此外，在进食时间前半段之前和期间以及后半段之前和期间，每对之间的变化存在高度相关性（r=0.642，P=0.013和r=0.579，P=0.030）。这些在统计学上显著高于独自用餐组（P=0.005和P=0.040）。
