Background Fatigue is a common problem in medical students and is thought to be related to poor academic performance. Fatigue is expected to be highly related to dietary habits, but previous research was not enough. Therefore, the aims of this study were to investigate the relationship between dietary habits and the prevalence of fatigue and also to give an update on basic research data for improving academic performance in medical students. Methods: The study group consisted of 170 healthy second-year medical students attending three university school of medicine in Busan. They completed a questionnaire dealing with fatigue (Fatigue Severity Scale), dietary habits, lifestyle, and academic performance. Results: On multivariate logistic regression analyses, skipping breakfast (completely skipping breakfast everyday versus having breakfast everyday; odds ratio 7.23; 95% confi dence interval, 2.07 to 25.28; P = 0.002) was positively correlated with the complaints of fatigue. Conclusion: Skipping breakfast was associated with the complaints of fatigue in medical students.
Background: In these days the metabolic syndrome threatens many people of Korea. Several studies have suggested that the dietary habits are associated with the risk of the metabolic syndrome. The purpose of this study was to find out relations between the components of the metabolic syndrome and the dietary habits. Methods: The subjects of this study included 1,005 non- smoking premenopausal females aged from 20 to 49 years old who visited the health promotion center of a university hospital. Dietary questionnaire was composed of dietary habits and specific food intake frequency during the past 3 months. Results: The subjects who had more than one metabolic components were 361 (36%), and those who had the metabolic syndrome was 35 (3.5%). After multivariate logistic analysis adjusted with age, BMI, smoking status, alcohol intake, and exercise, the abdominal obesity risk was significantly increased in those who had irregular meals (P for trend= 0.049), skip meals (P for trend=0.050), faster meal time (P=0.017), and intake of saturated fat more frequently (P=0.043). The abdominal obesity risk was significantly increased in those who overate or binged eating ≥3 times/week than <1 time/week {OR (95% CI), 2.49 (1.07∼5.80)}, intake fruit <1 time/week than 6∼7 times/week {OR (95% CI), 4.46 (1.20∼16.54)}. A risk for high blood pressure was significantly increased in those who had breakfast 1∼2 times/week than those had it 6∼7 times/week {OR (95% CI), 1.91 (1.07∼3.42)}. The risk for impaired fasting glucose was significantly increased in those had breakfast <1 time/week than those who had 6∼7 times/week {OR (95% CI), 2.27 (1.20∼4.28), P for trend=0.018}. Conclusion: There was a correlation between dietary habits and metabolic syndrome components. Among the dietary habits, irregular meals, skipping breakfast, skipping meals, fast meal time, overeating or binge eating tendency, low intake of fruits and high intake of saturated fat were associated with the risk of the metabolic syndrome components.

Background Recently, the prevalence of childhood obesity has increased dramatically, but the cause still remains incompletely understood. The goal of this study was to present a direction for treatment and prevention of childhood obesity on the basis of the data of physical activity energy expenditure, inactive time and dietary habits of Korean children. Methods: A total of 56 children were selected from 8 elementary schools in Seoul and Gwacheon-city. Children's physical activity pattern and dietary habits were obtained by questionnaire. The children wore accelerometer on their wrists from Friday to Tuesday over the whole weekend. Then, we calculated the activity energy expenditure using the activity counts recorded on the accelerometer. Results: Neither the physical activity energy expenditure (kcal/kg) nor the activity pattern showed a significant difference between the normal weight group and the overweight group. The overweight children spent more time watching TV and using the computer. The overweight group did not have breakfast and ate much more and faster in terms of dietary habit. Conclusion: This study suggests that bad habituations in diet and increase of inactivity time can play more important role than physical activity in causing overweight in 7-year-old children.

Background : Dyspepsia is a common symptom and bacause functional dyspepsia is a heterogeneous disorder its pathophysiology is not well established. We need to conceptualize in a so called "biopsychosocial model". Many Koreans tend to consider the importance of dietary habits in causes and treatment of diseases and actually many physicians recommend dietary modification for patients of functional dyspepsia. Therefore, the aim of the present study was to determine if dietary habits was associated with functional dyspepsia.
Methods : Functional dyspepsia was defined and classified by Rome II criteria. This study was performed by case and control method at the outpatient department of family medicine of six university hospitals in Seoul. Self-administered questionnaire for the demographic characteristics and dietary habits were performed in 472 functional dyspeptic patients and 236 normal controls.
Results : Only the economic status among the demographic factors was associated with functional dyspepsia and on the dietary factors. The functional dyspeptic patients reported less than 2 days regular eating for one week (OR=2.01, P=0.019, 95% CI: 1.12∼3.60) and more than 3 days overeating for one week (OR= 2.01, P=0.020, 95% CI: 1.12∼3.63), but no significant difference was found in the daily eating frequency, meal duration, frequency of spicy food comsumption, and breakfast.
Conclusion : Functional dyspepsia was associated with irregular eating patterns and overeating behavior for one week. To prevent functional dyspepsia behavioral modification such as eating regularly and avoiding overeating should be advised.
