An evaluation of the influence of nutritional health camp for in obese elementary students was assessed. Anthropometric measurement, 24-hour recall of dietary intake, MMTIC(Murphy-Meisgeier Type Indicator for Children) and questionnaire response(nutritional knowledge, nutritional attitude, and self-satisfaction) was documented in 43 obese elementary students(29 boys and 14 girls). The mean age of the elementary students was 11.2 years. The mean height, body weight and obesity index was 144.7 cm, 55.4 kg and 41.0% in boys, and 136.1 cm, 45.2 kg, 40.0% in girls. The mean energy intake was 1,522.4 kcal in boys and 1,494.9 kcal in girls. The subjects taking less than estimated average requirement(EAR) for vitamin ${B_2}$, folate, vitamin C and calcium was over 70%. A considerable number of students(65.1%) showed U band(undetermined character). The students demonstrated a propensity towards increased average nutritional knowledge and self-satisfaction after attending the nutritional health camp. In addition, a significant increase in average nutritional attitude was observed(p<0.001). The results of this study suggest that nutritional health camp positively influenced the nutritional attitude of elementary students.

Purpose: Adult Korean men belonging to the main economically active population are known to have long sedentary hours. This study was undertaken to determine the difference and relevance of sedentary hours on the nutrition, diet, and health status of adult men, and to suggest how to prevent health risk factors. Methods: Subjects (n = 1,068) were classified into 4 groups based on their sedentary hours, ranging from the first quartile (Q1) having the least hours spent sitting, to the fourth quartile (Q4) spending the longest hours. Results: Subjects belonging to Q4 had the lowest average age, the largest waist circumference, and the highest level of education. Among those engaged in economic activities, the ratio of white-collar workers was significantly higher in Q4. Accordingly, the rate of not doing high-intensity or moderate-intensity physical activity while working was also the highest in Q4. A significant difference was obtained in the drinking frequency between groups, but this was found to be associated with the average working hours rather than sedentary hours. The proportion of not doing aerobic exercise was higher with longer sitting hours. The highest diagnosis of diabetes (8.8%) was obtained in the Q4 group. Among the factors related to cardiovascular disease, only low density lipoprotein-cholesterol showed a significant difference, with Q4 being significantly higher than Q1. Considering energy and nutrient intake, vitamin B₁ and calcium intake were the lowest in the group with the longest sitting hours, as well as the least consumption of vitamin C than the recommended estimated average requirement. Conclusion: The results of this study suggest that the health and nutritional status of Korean adult men are affected by sedentary hours. This should be recognized as a health risk factor and guidelines need to be developed for sedentary lifestyle management.

This study examined to find out the relationship between nutritional knowledge and food habit of the students majoring food & nutrition(218 students) and the students majoring Korean oriental medicine(286 students). The results of this study are as follows; 1)The intake of vegetable and dairy products is high for the students majoring food & nutrition(p＜0.01), and the intake of instant food is low for the students majoring Korean oriental medicine(p＜0.01). 2)In the value of diet, the ratio which acknowledges the importance of the relationship between the diet and the nutrients is high for the students majoring food & nutrition (p＜0.01), and the ratio which acknowledges the diet as the way to remove hunger or to enjoy eating is high for the students majoring Korean oriental medicine(p＜0.01). The ratio of the students who acknowledge taste, nutrition and preference as the important factors in selecting foods is high for the students majoring food & nutrition(p＜0.01). The ratio of regularity in each meal, consuming time, and the food quantity is high for the students majoring Korean oriental medicine(p＜0.01). 3)The total score of 20 inquiring items about nutritional knowledge is high for the students majoring food & nutrition(p<0.01), and especially the mark is high in such items inquiring the relationship between animal fat and nutrition(p<0.01), the relationship between water and obesity(p<0.05), the relationship between cholesterol and food(p<0.01), the recommended energy quantity(p<0.05), and the vitamin B group (P<0.01). According to this study, it is hard to determine that there is inevitable positive relationship between diet habits and nutritional knowledge. The students majoring food and nutrition know better than the students majoring Korean oriental medicine about the relationship between diet, health and nutrients however they can not practice what they blow when selecting foods. On the other hand the students majoring Korean oriental medicine show lower marks in food habits and nutritional knowledge than those of the students majoring food and nutrition; however, they show higher marks in practicing regular diet. According to this result it is necessary to increase the subjects related nutrition in the curriculum not only lot the students majoring food & nutrition to practice their nutritional knowledge in their actual life but also for the students majoring Korean oriental medicine to obtain correct nutritional knowledge and information.

This study aimed to examine nutritional status and similarities of diets between Vietnamese female immigrants and Korean spouses and dietary changes of Vietnamese females after immigration. Subjects were 608 couples visiting 13 medical centers for the Cohort of Intermarried Women in Korea from November 2006 to November 2007. Anthropometric and biochemical measurements were obtained and dietary intakes were assessed using one-day 24-hour recall. Sixty-eight percent of wives answered there have been changes in their diets and consumptions of meats, fish, dairy products, vegetables, and fruits increased after immigration. Energy intakes of wives and spouses were 1491.7 kcal and 1788.8 kcal, respectively, showing most couples (80.1%) consumed less than the Korean estimated energy requirements. More than half of the couples were below the Korean estimated average requirements of zinc, vitamin $B_2$, and folate. The correlation coefficients between couples ranged 0.15-0.38 for unadjusted, 0.22-0.35 for per 1000 kcal, and 0.21-0.40 for energy-adjusted, respectively. The proportions of couples in the same quartiles of each nutrient intake and in the same answers of each question of Mini Dietary Assessment were about 30% across nutrients and around 50% across questions. The length of residence is related to similarities of nutrient intakes between couples: similarities decreased after 3 years of residence in Korea. In conclusion, nutritional intakes of inter-married couples were inadequate although wives reported that their dietary intakes increased after immigration. Inadequate nutrient intakes of wives were partly explained by similar diets between couples because these wives without enough adjustment to Korean culture were more likely to follow what their spouses ate. Findings from this study may be helpful to improve the nutritional status of inter-married couples and make policies and programs for them. A follow-up study should identify factors affecting inadequate nutritional status of intermarried couples and similarities of their diets.

The purpose of the study was to investigate nutritional status of chronic obstructive pulmonary disease (COPD) patients and to find out the differences according to the stages of disease. From March to October, 2006, 41 stable male patients of mild to severe COPD patients were recruited from Seoul National University hospital. The patients' of body weight and fat free mass were assessed by bioelectrical impedance analysis. The nutritional status of the patients was also assessed by 3-day recall, index of nutritional quality (INQ), dietary diversity score (DDS), dietary variety score (DVS), food group index pattern and dietary quality index (DQI). The total of 41 patients were classified into three groups, stage I, stage II and stage III groups according to the classification of Global Initiative for Chronic Obstructive Lung Disease (GOLD) standard. The mean age of the patients in each stage were 67.2-66.9 years showing no significant difference. The ratio of $FEV_1$/FVC were $57.5{\pm}7.3$, $46.9{\pm}7.6$ and $38.2{\pm}6.8%$, respectively showing significant differences according to the stages of disease. The fat free mass of the stage II ($48.2{\pm}4.7kg$) and III ($47.3{\pm}4.5kg$) was significantly lower than that of stage I ($53.1{\pm}6.9kg$) patients. There were significant correlation of fat free mass with $FEV_{1}$, and BMI (body mass index) with $FEV_{1}$/FVC ratio (p < 0.05). COPD patients showed the diet-related clinical symptoms of anorexia, dyspnea, dyspepsia, and chewing difficulty. Daily intakes of calorie, K, vitamin $B_2$ and folate of the patients were very low ($83.8{\pm}20.7%$, $58.9{\pm}14.4%$, $70.7{\pm}19.6%$ and $74.4{\pm}10.2%$, respectively) however, they did not significantly different according to the stages of disease. Daily intake of calcium was significantly lower in the stage III patients (p < 0.05). The mean scores of dietary variety score was significantly lower in the stage III patients (p < 0.001). Dietary quality index of the patients were not different among the stages of disease and the scores indicated poor quality of diet. As a summary, we found that body fat free mass, regularity of exercise, frequency of having snacks and dietary variety score were significantly associated with the severity of chronic obstructive pulmonary disease.

The purpose of this study was to investigate the health status and food habits of male college students in Seoul according to drinking habits. In order to identify risk factors, health surveys were conducted from October 2013 to December 2013. Average height, weight, and BMI of subjects were $175.47{\pm}5.27cm$, $67.93{\pm}9.28kg$, and $22.04{\pm}2.67kg/m^2$, respectively. Weight and BMI were higher in the non-drinking groups compared to the drinking groups (p<0.05). Frequency of drinking was 2~3 times per month, and 52.4% of subjects started drinking when starting university. The motivation to start drinking was cited as "From necessity". Reason for drinking was "Social relations". The favorite kind of drink was beer. Rate of taking supplements was 24.4% of the subjects. Vitamin preparations were highest in drinking groups and non-drinking groups (p<0.05). The reasons for skipping meal were "too busy" in the drinking groups, and "oversleep" in the non-drinking groups (p<0.05). The preference for snacking in drinking groups were milk, milk products, and fast food, with the highest being listed first. The non-drinking groups preferred carbonated drinks and ice cream. The drinking groups need more education about their drinking habits. Drinking groups also need an increased intake of vegetables and fruits.

Milk and dairy products are the high value foods for the elderly population. In particular, fermented milk is the best source of calcium for people in the specific age group of over 79 years. It provides a good source of protein. Regular exercise and active lifestyle are recommended to slow down the muscle loss. However, exercising without proper nutrient intake is simply not sufficient at this age. Milk and dairy products provide the iron and protein content required for effective exercise-assisted growth. Milk nutrients have the advantage of being produced in various food forms, such as liquid, semi-solid, and powder types. Fat-soluble vitamins such as retinol and vitamin K can be encapsulated using various technologies for milk and dairy products. Using the encapsulation method, spray drying and fluidized-bed coating have been used for adding the micro-nutrients to the food. Microencapsulation technology is being applied in case of the fermented dairy products too. In particular, various wall materials are being developed to enhance the viability of probiotics. In the near future, advanced high-efficiency technologies that can effectively nourish the dairy products with nutrients will be developed to produce targeted high-nutrition value food for the elderly.

The purpose of this study was to investigate nutrient intake and bone status in rural postmenopausal women in Korea. Ten postmenopausal women in An-Sung area participated in this study and they were divided into two groups ; women in group I had been postmenopausal for 4 years or less and those in group II had been postmenopausal for 5 years or more before the present study began. Their environmental factors and dietary intakes were surveyed through the personal interviews. Serum levels of calcium, phosphorus, parathyroid hormone(PTH), estradiol and urinary Ca, P, creatinine, hydroxyproline levels were measured from December 4 to December 27 in 1993. The reults of this study are summarized as follows : Average ages of group I and II were 54.8 and 57.2 years. Average menopausal ages of group I and II were 50.8 and 47.3 years. The nutrient intakes of subjects were higher than recommended dietary allowances(RDA) except calorie, protein, calcium, and vitamin A. The nutrient status did not show any significant difference between group I and II. Serum levels of Ca, P, PTH, estradiol and urinary P, creatinine excretion did not show any significant difference between group I and II, and all levels were in normal range. Urinary Ca excretion(p<0.05) and hydroxyproline excretion(p<0.01) were significantly lower in group I than in group II. Urinary Ca/creatinine(Ca/cr) and hydroxyproline/creatinine(Hpr/cr) rations were significantly higher in group II than in group I(p<0.01. And Hpr/cr levels of group I were in normal range, but most of subjects in group II were higher than 0.017 indicating sign of osteoporosis. Correlations between parameters showed that serum PTH adn urinary Ca, Ca/cr levels were positive related (p<0.01), and the years of the after menopausal year and urinary Hpr/cr was also positive related(p<0.05). The present results suggests that it is difficult to protect postmenopausal women's bone destruction having Korean usual diets. Therefore, to prevent osteoporosis with aging, minimizing the hormonal changes in postmenopausal women is needed as well as Ca supplementation and proper exercise before menopause begins.

The purpose of this study was to investigate the eating habits and eating behaviors, nutrition knowledge of students in 4, 5 and 6th graders of elementary school in Jeonju Area. The subjects for questionnaire were 2,568 elementary school students (boys 1,364, girls 1,204). The results were analyzed by SPSS program, and were as follows. In anthropometric data, there were significant differences between boys and girls. In eating habits and eating behaviors, there were significant differences in the rate of 'Hasty eating habit(p<0.01)', 'Most heavy meal(p<0.01)', 'Eating when receive stress(p<0.05)', and 'Frequency of snack eating per day(p<0.01)' between boys and girls. In total scores of nutrition knowledge, there were significant differences between boys and girls. In nutrition knowledge, there were significant differences in the rate of 'Carbohydrate and fat give heat and force.(p<0.001)', 'Carbohydrate is nutrient that make muscle and blood of our body.(p<0.01)', 'Overeating of carbohydrate does not contribute gain of weight. (p<0.05)', To intake vitamin, it is good to eat fresh fruit and vegetable.(p<0.01)', 'Calcium deficiency is leading to anemia.(p<0.001)' between boys and girls. In conclusion, systematical educational programs need to be developed at elementary school. These should include information about achieving a balanced diet, good eating habit and behavior, meal management and Korean dietary culture. Also, nutritional education at home must be emphasized.

This study investigated the effects of the nutrition education on body weight, visceral fat and diet quality in the postmenopausal women. The subjects (n = 101) were randomly divided into two groups: Nutrition education + Exercise (NEE) group (n = 51) and Exercise only (EO) group (n = 50). Nutrition education was consisted of counseling in portion control, food selection for low carbohydrate, high fiber food items and for the improvement in micronutrient intakes and diet quality. After 6 months, the reduction in the body weight and visceral fat area was significantly greater in the NEE than in the EO group. The NEE subjects were further divided into two groups according to the amount of visceral fat area reduction; high visceral fat area loss (HVL) group with a visceral fat area reduction 2.35% or greater and low visceral fat area loss (LVL) group with a reduction less than 2.35%. In the HVL group, the reduction in body weight, BMI, percent body fat, waist to hip ratio and visceral fat area was significantly greater than that in the LVL group. We observed a significant increase in the serum HDL-cholesterol level and a decrease in systolic blood pressure, fasting blood sucrose, total and LDL-cholesterol levels in the HVL group compared to the LVL group. The energyadjusted protein, fiber, calcium, vitamin $B_6$, vitamin C, vitamin E intakes were significantly increased in the HVL compared to LVL group. The index of nutritional quality (INQ) and mean adequacy ratio (MAR) were also increased in the HVL group compared to the LVL group. These results show that our nutrition education program was an effective intervention measure for the reduction of body weight and visceral fat, blood pressure, glucose and lipid levels in the blood and also for the improvement of nutrient intake and diet quality in postmenopausal women who are overweight.
