The purpose of this study was to identify the relationships between perceived stress, ego-resilience, and premenstrual syndrome(PMS) and investigate the factors affecting PMS in female college students. The study participants were 215 female college students in Gyeunggi province. Data were collected from October 10 to November 10, 2017, using self-report questionnaires. Collected data were analyzed using descriptive statistics, Pearson correlation coefficients, and multiple regression analysis. PMS was positively correlated with the perceived stress and negatively correlated with ego-resilience. Eating habits, interference with daily life by menstruation, perceived stress accounted for 44.4% of variance in PMS. Based on these results, it is necessary to develop a management program that integrates psychological factors and lifestyle improvement including dietary habits, as well as efforts to manage menstrual symptoms in order to alleviate the premenstrual syndrome of female college students.

BACKGROUND/OBJECTIVES: Nutrition knowledge has been reported to have a weak positive effect on healthy eating behavior. This study aimed to determine if there was a difference in nutrition knowledge depending on the choice of science subject in high school and whether that affected the actual eating habits of college students in Japan. SUBJECTS/METHODS: The subjects were 514 college students, the majority first-year students, in 3 cities in Japan. A questionnaire survey was conducted on elective subjects in science in high school, diet (11 items), lifestyle (5 items), and nutrition knowledge (34 questions). The preliminary survey was conducted on 47 students in the fall of 2019, and the full-scale survey was conducted in May-June and October-November 2021 at the end of lectures for the first-year students. RESULTS: The students in the high-score group (24-31 points, n = 180) had a higher intake of vegetables (odds ratio [OR], 1.78; 95% confidence interval [CI], 1.12-2.82; P = 0.015) and breakfast (OR, 1.64; 95% CI, 1.03-2.60; P = 0.035), and a reduced intake of fast food (OR, 0.27; 95% CI, 0.14-0.51; P < 0.001) than those in the low-score group (6-19 points, n = 150). Only the biology and chemistry students had significantly higher nutrition scores than the other groups (all: P < 0.001), but no significant difference was found between the other groups. Understanding nutrition learned in elementary and junior high school is appropriate, while molecular structure, recommended amount, and food poisoning were insufficient. CONCLUSIONS: Knowledge of nutrition appears to have a positive effect on the actual eating habits of college students. Although biology and chemistry in high school may help students understand the foundations of good nutrition, specialized food education may be required to make informed dietary choices.

Sarcopenia is an increasingly common disease among the elder that has recently received attention. Although the causes of sarcopenia are diverse, aging, dietary habits, lack of exercise are the one of the major factors. As the causes of sarcopenia are diverse, it is important to develop strategies for prevention and treatment. However, predicting sarcopnia accuartely is difficult due to the variety of factors involved. Here, machine learning can significantly improve the accuracy and convenience of predicting sarcopenia. However, since lifestyle habits and biological data are vast, using data without preprocessing may be inappropriate in terms of time complexity and accuracy. This paper reviews recent literature on sarcopnia and its causes, focusing on preprocessing the data to be used in sarcopnia prediction machine learning accrodingly.

This study was undertaken to analyze the growth, nutritional, and dietary risk factors of elementary school students belonging to the Busan Metropolitan City Office of Education and provide the basic data needed to develop an underweight and obesity prevention program. In 2021, BMI and Dietary Screening Test (DST) data of 4,046 children surveyed by the Nutrition Education Experience Center's "Diagnosis System" of the Busan Regional Office of Education were analyzed. The DST consists of 36 questions about lifestyle habits, meal quality, meal regularity, snack quality, and eating behavior. Of the children included, 6.8% were underweight, 65.4% were normal weight, 13.4% were overweight, and 14.4% were obese. Children in the obesity group had shorter sleep and meal times (P<0.001), lower vegetable and fruit consumption frequencies (P<0.001), higher fast food consumption frequencies (P<0.001), higher rates of skipping meals (P<0.01) and breakfast (P<0.001), and more frequently used smartphones and watched TV during meals (P<0.001). The underweight group had the highest scores for all eating development factors but more frequently had chewing and swallowing difficulties (P<0.001). The study confirms underweightedness and obesity are present different problems and indicates that nutrition teachers should conduct accurate studies on the eating habits and behaviors of obese and underweight students and provide individually tailored nutritional counseling.

Objectives: The purpose of this study is to investigate the diagnostic factors of Damjeok in the literature. Methods: This study used the databases of five (Mediclassics, RISS, KMbase, OASIS, CNKI) to analyze diagnostic factors of Damjeok. Literatures published by May 2023 were assessed and we classified 91 literatures dealing with diagnostic factors by 5 categories, 'characteristics', 'location', 'symptom', 'pulse wave & tongue feature', and 'eating habits & lifestyle'. Results: Damjeok is mainly formed at the stomach in the form of lump or hard seed, and it can be observed in other regions or even the whole body by its trait of floating. Damjeok mainly shows symptoms of the digestive system and also causes various symptoms associated with the respiratory system and infection, musculoskeletal system, urogenital system, neuropsychiatric system and cardiovascular system. Regarding pulse wave and tongue feature, a slippery wave and greasy coated tongue are typical features of Damjeok. Additionally, bad eating habits and a lack of exercise have been described as a factor that cause and aggravate Damjeok. Conclusions: The two most important factors in the diagnosis of Damjeok are abdominal stiffness by physical examination and digestive symptoms, and these correspond to the definition of a syndrome. Diagnostic factors based on literature evidence will provide clues to the clinical diagnosis of Damjeok syndrome.

Purpose: Cardiovascular disease is one of the major causes of death not only in Korea but also worldwide. Atherogenic index of plasma (AIP) has been extensively investigated, but studies on nutritional intake and eating habits are scarce. The purpose of this study was to analyze the general characteristics, dietary habits, and nutritional status of Korean adults based on their AIP values using data from the 2013-2015 Korea National Health and Nutrition Examination Survey. Methods: A total number of 3,040 adults in their 20s and 30s were included as study subjects. They were divided into quintiles according to their AIP values. Comparisons were then made among the general information, eating habits, and nutritional intake statuses of the groups. Results: The averages of AIP were different by age, obese status, education, occupation, alcohol drinking frequency, smoking, and exercise in men. As for women, the averages of AIP were different by age, obese status, education, occupation, alcohol drinking frequency, and smoking status. Except for high-density lipoprotein (HDL)-cholesterol, higher AIP values in men were associated with significant increasing trends in health indicators, including systolic and diastolic blood pressure, fasting blood glucose, insulin, hemoglobin A1c, total cholesterol, triglyceride, and low-density lipoprotein (LDL)-cholesterol. As for women, as AIP increased, systolic and diastolic blood pressure, fasting blood glucose, insulin, total cholesterol, triglyceride, and LDL-cholesterol showed significant increasing trends except HDL-cholesterol. HDL-cholesterol showed a significant decreasing trend as AIP increased in men and women. In the high AIP group of women, the frequency of breakfast was lower, whereas the frequency of alcohol beverage consumption was higher. Conclusion: Among young adults, the risk of arteriosclerosis was higher in obese, smoking, and non-exercise individuals. More frequent alcohol drink consumption in women is associated with a higher risk of arteriosclerosis. Therefore, weight and lifestyle management are necessary for the prevention of atherosclerosis among young adults.

Purpose: This study examined the relationship of the nutrition of rice and the positive evaluation of the rice-based meal with the food consumption habits, physical and emotional health status, and learning efficacy of 601 middle and high school students in Jeonju area. Methods: The participants were divided into two groups using cluster analysis in that the participants belonging to the upper groups had a center score of 46.86 (n = 348), while the people belonging to the lower group had a center score of 36.89 (n = 253). Statistical differences were tested for all the relationships between the physical and emotional health symptoms and learning efficacy between the groups at the ${\alpha}=0.05$ level. Results: Significant differences in the physical self-evaluated symptoms were observed in all five items in each cluster (p < 0.05). In the case of the emotional health status, nine out of 10 items showed significant differences between the groups. Similarly, significant differences in all five items in learning efficacy questionnaire were noted (p < 0.05). Positive attitudes of the parents toward having breakfast also showed significant differences among the groups. Conclusion: The nutrition of rice and a positive evaluation of the rice-based meals significantly affect the physical and emotional health status and learning efficacy of juveniles. These findings can be used as baseline information for promoting nutrition education, particularly rice-based breakfast.

This study was carried out to obtain information related to life styles, nutrition knowledge, and dietary habits according to gender and weight status of college students in Ulsan. The subjects were 324 college students (144 males, 180 females), and they were divided into three groups based on BMI. The average BMI was $21.0kg/m^2$, and the BMI of underweight, normal, and overweight students were 15.4%, 63.0%, and 21.6%, respectively. Among the male students, 0.1% and 34.0%, and among the female subjects, 27.2% and 11.7%, were included in the underweight and overweight groups, respectively. For dietary habits, the rate of skipping breakfast (34.9%) was considerably higher than those skipping lunch and dinner. Overall, the nutrition knowledge score, which was assessed by 15 questions, was somewhat low (44.9/100), yet, it was higher in females than in male students. There were significant differences among gender and weight status in several items of dietary habits such as the speed of eating meals, consuming breakfast on a regular basis, and sleeping hours. 40% of the subjects had appropriate knowledge about high calorie foods with low nutritional value. In the blood analysis of the subjects, males had higher hemoglobin levels than females. Further, more females were included in the risk group of Hb, total cholesterol, and LDL. These results suggest that in order to develop nutrition education programs for college students, differences between gender and weight status, dietary habits, and nutrition knowledge level should be considered.
