Abstract

BACKGROUND

The purpose of the present research was to identify nutrients related to sleep bruxism and to establish a hypothesis regarding the relationship between sleep bruxism and nutrients.

METHODS

We recruited 143 Japanese university students in 2021 and assigned them to sleep bruxism ( = 58) and non-sleep bruxism groups ( = 85), using an identical single-channel wearable electromyography device. To investigate nutrient intakes, participants answered a food frequency questionnaire based on food groups. We assessed differences in nutrient intakes between the sleep bruxism and non-sleep bruxism groups.

RESULTS

Logistic regression modeling showed that sleep bruxism tended to be associated with dietary fiber (odds ratio, 0.91; 95% confidence interval, 0.83-1.00; = 0.059). In addition, a subgroup analysis selecting students in the top and bottom quartiles of dietary fiber intake showed that students with sleep bruxism had a significantly lower dietary fiber intake (10.4 ± 4.6 g) than those without sleep bruxism (13.4 ± 6.1 g; = 0.022).

CONCLUSION

The present research showed that dietary fiber intake may be related to sleep bruxism. Therefore, we hypothesized that dietary fiber would improve sleep bruxism in young adults.

摘要

背景

本研究的目的是确定与睡眠磨牙症相关的营养素，并建立关于睡眠磨牙症与营养素之间关系的假设。

方法

2021年，我们招募了143名日本大学生，使用相同的单通道可穿戴肌电图设备将他们分为睡眠磨牙症组（n = 58）和非睡眠磨牙症组（n = 85）。为了调查营养素摄入量，参与者回答了一份基于食物类别的食物频率问卷。我们评估了睡眠磨牙症组和非睡眠磨牙症组之间营养素摄入量的差异。

结果

逻辑回归模型显示，睡眠磨牙症倾向于与膳食纤维相关（比值比，0.91；95%置信区间，0.83 - 1.00；P = 0.059）。此外，对膳食纤维摄入量处于前四分位数和后四分位数的学生进行的亚组分析表明，患有睡眠磨牙症的学生膳食纤维摄入量（10.4±4.6克）显著低于无睡眠磨牙症的学生（13.4±6.1克；P = 0.022）。
