This study examined the nutritional status and dietary behaviors of university students in Gangwon-do as well as the effects of dietary education on them. Forty college students were recruited, and their dietary lifestyle was examined using an Adult NQ questionnaire before and after dietary education. The questionnaire items were grouped into four categories: balance, diversity, moderation, and dietary behavior. The mean NQ score out of 100 was 48.00. Among the three grades of the NQ grade criteria, most subjects (50%) were in the lowest grade, which was poor. The mean scores of the NQ factors were highest for moderation (68.76%), followed in order by diversity (50.81%), dietary behavior (45.66%), and balance (21.01%). Compared to the criterion value, moderation was only good, and balance was the worst. These results suggest that the nutritional status of the subjects is poor. On the other hand, there was a significant change in the areas of the NQ score (53.7), balance (29.22) and dietary behavior (56.77) after dietary education. Nevertheless, the 'balance' area remained lower than the average, highlighting the need for education on food intake to enable diverse food intake.

BACKGROUND/OBJECTIVES: The study was performed to investigate health-related lifestyle, dietary habits, and depression according to exercise frequency to understand complex factors that affect effective health management. Thus, exercise frequency, health-related lifestyle, dietary habits, and depression were evaluated in college students in Seoul and Gyeonggi-do areas. SUBJECTS/METHODS: A survey was conducted on college students, aged 19-29, in Seoul and Gyeonggi-do areas from May 13 to May 31, 2020. A total of 594 questionnaires were collected and 566 (269 from males, 297 from females) were statistically analyzed, except 28 with incomplete responses. Collected data were analyzed using SPSS WIN 21.0 program. RESULTS: The sex distribution of the 3 groups according to exercise frequency was significantly different; the ratio of males in over 3 times/week group was significantly higher than those in 1-2 times/week group and no-exercise group (P < 0.001). The height (P < 0.001), weight (P < 0.001), and body mass index (P < 0.05) were significantly higher in over 3 times/week group compared to no-exercise group. The ratio of subjects who answered 'good' or 'very good' for subjective health condition was significantly high in the order of 'over 3 times/week' group (59.1%), '1-2 times/week' group (34.5%), and 'no-exercise' group (25.0%) (P < 0.001). The ratio for meal regularity was high as 56.6% in 'over 3 times/week' group and the ratio for irregular meals was significantly higher in 'no-exercise' group (67.2%) and '1-2 times/week' group (54.9%) (P < 0.001). Among questions on dietary habits, 'Eat meat, fish, egg or beans' (P < 0.01) and 'Eat fruit' (P < 0.01) were significantly higher in 'over 3 times/week' group compared to 'no-exercise' group. 'Drink more than 2 liters of water' (P < 0.001) was 0.70 in 'over 3 times/week' group, which was significantly higher than 0.54 in '1-2 times/week' group and 0.38 in 'no-exercise' group. Moderate depression and severe depression that need treatments were significantly lower in 'over 3 times/week' group (18.7%) compared to '1-2 times/week' group (26.0%) and 'no-exercise' group (29.7%) (P < 0.05). CONCLUSIONS: It is considered that combined intervention for exercise habits, proper dietary habits, and depression management is needed for effective health management.

This study was performed to determine dietary and lifestyle factors associated with hypertension in Korean adolescents. Study subjects were 12~19 years (n = 521) adolescents who participated in the 2005 Korean National Health and Nutrition Examination Survey (KNHANES III). Subjects were divided into the hypertensive group (HG, n = 102) and normotensive group (NG, n = 419) by '2007 Korean children and adolescents growth standard' and the relationships between blood pressure and physical measurement, nutrients intakes, eating behaviors and health related factors were analyzed. HG showed significantly higher levels in weight, waist circumference and BMI than NG. The amount of nutrient intakes was not different between NG and HG. Index of nutritional quality (INQ) for phosphate was higher in HG compared with NG. In both male and female HG, INQ for iron was higher but INQ for vitamin B1 was lower than NG. HG revealed higher consumption frequencies of snack, yoghurt, and ice cream compared with NG. In eating and behavioral factors, 'dinner with family', 'eat proper amount', 'keep Korean traditional diet', alcohol drinking, and mean alcohol intake were significantly different between the two groups. By logistic regression method, risk factors for hypertension revealed in this study were gender (male), age (15~19 years), BMI (${\geq}\;85$ percentile), and not keeping Korean traditional diet. These results suggest that education program for hypertension prevention in adolescents should include eating habits improvement and lifestyle modification as well as weight control.

The purpose of this study was to examine the effects of a lifestyle consisting of a health oriented diet and personal motivation toward health improvement on an individual's desire to participate in condolence or "healing" -workshops and programs. In order to examine the influence of the "health diet" and motivation, the "health diet" lifestyle was classified into nutrition pursuit factors, psychological factors, food safety factors, and health conscious consumption factors. Personal motivation was categorized into perceived benefits, environmental factors and the individual's desire for happiness. Empirical analysis showed that nutrition pursuit factors had an impact on perceived benefits and the desire for happiness. Psychological aspect factors had a significant influence on perceived benefits, environmental factors and the desire for happiness. However, food safety factors and health conscious consumption factors did not have an effect on individual motivation to improve health. Regarding personal motivation toward health improvement on the desire for "healing", perceived benefits and environmental factors had significant influence. However, the individual's desire for happiness did not influence the demand for "healing". Regarding the effect of a "health diet" on the desire for "healing", only the psychological aspects of a "health diet" had any significant effects on the desire for "healing". The results from this study can help local organizations or service companies that provide "healing" programs with developing effective marketing strategies that could lead to greater customer satisfaction. Especially, the significant influence of psychological aspects of a "health diet" on the demand for "healing" is noteworthy in that this could play a key role in establishing a more effective marketing strategy to attract increasing numbers of consumers using health conscious diets.

In this study, we compared demographic anthropometric characteristic, health-related lifestyle and diet behavior among weight control behaviors of 1187 (555 male, 632 female) aged $40{\sim}69yrs$ in Ganghwa country. All the data were analyzed by chi-square test, trend test, student t-test using SPSS 12.0 version at p < 0.05. 'Attempting weight control (loss)' was more in women than that was found in men (36.6% vs 20.7%), and women attempting weight loss most were 40-50 yrs. The reasons of weight loss were 'health problem' and 'health promotion'. Physical activity and diet restriction were commonly employed as weight control methods. Both genders attempting weight loss had a higher education level, BMI, percentage of body fat, waist circumference and physical activity than those not attempting weight control (p < 0.05). In dietary habits like 'meal regularity', 'slow eating' and 'over eating', women attempting weight loss were superior than those who not attempting weight control group (p < 0.05). Eating pattern changes like 'decrease of fats and fatty foods intake', 'vegetable oil usage', 'increase of fruit and vegetables intake', 'decrease of sugar and salt intake' showed significant differences (p < 0.001) between the attempted weight control groups and nonattempted weight control groups. Salt taste was a preference in male non-attempted weight control group, while sour, hot and spicy taste were preference in female attempted weight control group (p < 0.05). Preference for processed foods, fried foods and snack were significant differences (p < 0.05) in women attempted weight control group. Those attempting weight loss tried to improve their eating patterns. However, those attempting weight loss were poorer than the others in health-related lifestyle and eating habit. Therefore, it is necessary to make an effort that improve healthrelated lifestyle and diet behavior in middle aged group.

This study is to investigate the difference of depression and aggression according to lifestyle habits in 135 patients with coronary artery disease. The survey was conducted from May 13 to May 15, 2019. In order to investigate the difference of depression and aggression according to lifestyle, independent sample t-test and one-way ANOVA were conducted. Post-hoc analysis was conducted when there was a difference between depression and aggression. The results of the analysis showed that the group with relatively high smoking and drinking was high in physiological depression and the group with active participation in exercise and dietary control showed low physiological depression. The group with more alcohol intake showed higher level of verbal aggression, physiological aggression, and aggressive attitude than the group without alcohol. The group that participated actively in physical activity showed lower physiological aggression and aggressive attitude than the group without active aggression. It was found that the group that participates hard in dietary control is less aggressive than the group that does not.

Over the past few decades, changes in patterns of behavior (e.g., diet, smoking, alcohol consumption, and physical activity) have led to major changes in health status, characterized by increases in obesity, Type II diabetes mellitus, cardiovascular disease, and some cancers. This epidemiologic transition is largely the result of rapid increases in immigration to developed countries and rural-urban migration within developing countries, which is usually accompanied by environmental and lifestyle changes. In particular, adoption of “Western” dietary patterns, which tend to be high in fat and low in fruits and vegetables, is of concern since diet is a potent contributor to chronic disease risk. However, until recently, the process by which immigrants and rural-urban migrants adopt the dietary practices predominant in their new environments, known as dietary acculturation, has received very little research attention. Dietary acculturation is multidimensional, dynamic, and complex, and varies considerably depending on a variety of personal, cultural, and environmental characteristics. Therefore, to intervene successfully on the negative aspects of dietary acculturation, it is important to understand the process and identify factors that predispose and enable it to occur. The purpose of this article is to provide a practical model for understanding and investigating the effect of dietary acculturation on food and nutrient intake. Thus, this report 1) gives an overview of acculturation, 2) defines dietary acculturation and presents a model for how it occurs, 3) discusses measurement issues around dietary acculturation,4) reviews the literature on dietary acculturation in Korean Americans; 4) suggests a paradigm for acculturation research; and 5) offers some recommendations for future research in this area.

This study was conducted to examine the differences in perceived body weight and image and various lifestyles based on the self-rated health of university students when gender was adjusted. Five hundred fifty-five participants were asked their perceived health condition, and 58, 289, 160 and 48 students answered themselves as "very healthy", "healthy", "normal", and "unhealthy", respectively. As compared to the other 3 groups, "unhealthy" group showed higher proportions in dissatisfaction of body weight and negative perception of body image (P < 0.01). As health related lifestyles, "very healthy" group reported longer sleeping time than "unhealthy" group (P < 0.05), and had a higher proportion of people with regular exercise. Among the dietary behaviors, the frequencies of followings significantly different among the groups: "Regularity of meal time" (P < 0.01), "Eat protein foods more than twice a day" (P < 0.001), "Eat vegetables" (P < 0.01), "Eat fruit and fruit juice" (P < 0.01), "Eat vegetable oil added foods" (P < 0.01), "Eat seaweed" (P < 0.01), "Eat breakfast" (P < 0.01), "Modulation in animal fat and high in cholesterol intake" (P < 0.01). Particularly, higher proportion of subjects answered "very healthy" had higher frequencies (6-7 times/week) of these dietary behaviors. Overall results suggest that healthy lifestyle including adequate sleeping time, regular exercise, and good dietary behaviors might be potential factors affecting positive perception of health. In addition, positive perception of body weight and image were related with positive perception of health.

BACKGROUND/OBJECTIVES: Abdominal obesity is associated with metabolic disorders, and, in recent years, its prevalence in Korea has continuously increased. The change of lifestyle, particularly diet, is critical for the reduction of abdominal obesity. This study evaluated the effectiveness of an intervention focused on dietary self-efficacy and behaviors on the improvement of abdominal obesity. SUBJECTS/METHODS: Abdominally obese adults with additional cardiovascular risk factors were recruited through 16 medical facilities in South Korea from the year 2013 to 2014. The participants were randomly divided into 2 groups: an intensive intervention group (IG) that received a multi-component intervention to reduce abdominal obesity, by mainly focusing on dietary attitude and dietary behavior change, and a minimal information intervention group (MG) that received a brief explanation of health status and a simple recommendation for a lifestyle change. The interventions were provided for 6 mon, and health examinations were conducted at baseline, 3-, 6-, and 12-mon follow-ups. A path analysis was conducted to identify the process governing the changes in abdominal obesity. RESULTS: The IG showed an improvement in self-efficacy for eating control and diet quality at 6-mon follow-up. Abdominal obesity improved in both groups. Waist circumference was observed to be decreased through the path of "improved self-efficacy for eating control in food availability-eating restriction-improved dietary quality" in IG. Most changes in follow-ups were not significantly different between two groups. CONCLUSIONS: The intensive program targeting the modification of dietary behavior influenced management of abdominal obesity, and the effect occurred through a step-by-step process of change in attitude and behavior. Generally, improvements were also seen in the MG, which supports the necessity of regular health check-ups and brief consultation. The results can be used for further development and implementation of more successful interventions.

Objectives: This study was conducted to assess the eating behavior, growth, and dietary practices of children aged 3~5 years living in the Seoul and Gyeonggi Provinces. Methods: Self-administered questionnaires were completed by 237 mothers of preschool children between April and June 2018. Z-scores for weight-for-age, height-for-age, and BMI-for-age were calculated to determine the children's growth status. Dietary practices were evaluated using the nutrition quotient for Korean preschoolers (NQ-P). Results: In our study, 29.5% of children were in the eating-small-amounts group, 46.8% of children were in the neophobic behavior group, and 61.2% of children were in the refusal-of-specific food group. Specific foods found to have a high frequency of rejection are listed in descending order as follows: shellfish, soy, mushroom, shrimp, vegetables, milk, eggs, yogurt, seaweed, meat, fruits, and fish. The eating-small-amounts group had lower Z-scores for weight-for-age, height-for-age, and BMI-for-age than the non-picky eaters' group. Compared to the non-picky eaters' group, the eating-small-amounts group of picky eaters had lower scores on the moderation and environment items of the NQ-P, the neophobic behavior group had lower scores on the balance and environment items of the NQ-P, and the refusal-of-specific food group had lower scores on the balance, moderation, and environment items of the NQ-P. Conclusions: Children classified with picky eating behavior had lower growth and development, lower diet diversity, less balanced food intake, and had greater difficulty in abstaining from eating unhealthy foods than non-picky eaters. Therefore, a lot of patience and intensive efforts are needed to encourage children to encounter, experience, and accept unfamiliar food. It is more effective to provide eating behavior guidance by gently encouraging children, than by being strict and forceful. Besides, since the eating behavior of children is influenced maximally by the dietary lifestyle at their homes, it is important to ensure that a healthy dietary lifestyle is maintained at home.
