Abstract

OBJECTIVE

Fatigue, which is a common complaint among medical students, is related to poor academic outcomes. Because impaired dietary habits, such as skipping breakfast and taking meals irregularly, are correlated with poor school performances, whether those dietary habits were associated with the prevalence of fatigue was determined in medical students.

METHODS

The study group consisted of 127 healthy second-year medical students attending Osaka City University Graduate School of Medicine. They completed a questionnaire dealing with fatigue (Japanese version of the Chalder Fatigue Scale), lifestyle, and academic performance.

RESULTS

On multivariate logistic regression analyses adjusted for age, gender, body mass index, and nocturnal sleeping hours, skipping breakfast (completely skipping breakfast everyday versus having breakfast everyday; odds ratio 7.81, 95% confidence interval 2.00-30.52, P = 0.003) and taking meals irregularly (completely irregular versus always regular; odds ratio 6.89, 95% confidence interval 1.20-39.55, P = 0.030) were positively correlated with the prevalence of fatigue.

CONCLUSION

Skipping breakfast and taking meals irregularly are associated with the prevalence of fatigue in medical students.

摘要

目的

疲劳是医学生常见的主诉，与学业成绩不佳有关。由于诸如不吃早餐和饮食不规律等不良饮食习惯与学业成绩差相关，因此本研究旨在确定这些饮食习惯是否与医学生疲劳的发生率有关。

方法

研究组由127名就读于大阪市立大学医学研究生院的健康二年级医学生组成。他们完成了一份关于疲劳（Chalder疲劳量表日语版）、生活方式和学业成绩的问卷。

结果

在对年龄、性别、体重指数和夜间睡眠时间进行调整的多因素逻辑回归分析中，不吃早餐（每天完全不吃早餐与每天吃早餐相比；比值比7.81，95%置信区间2.00 - 30.52，P = 0.003）和饮食不规律（完全不规律与总是规律相比；比值比6.89，95%置信区间1.20 - 39.55，P = 0.030）与疲劳发生率呈正相关。
