In order to identify valuable factors for improving dietary quality of Korean rural elderly, the consumption frequency of food groups, dietary habits and health behaviors related to nutrient intakes of the elderly over 85 of Sunchang County were studied. The 171 subjects (61 males and 110 females) were chosen from Sunchang Province by stratified sampling. Among food groups, the consumption frequency of meat and fish groups influenced significantly on their nutrient intakes than the other groups. The subjects consuming more than 4 times per week of meat or fish had significantly higher nutrient intakes level than the other groups. The group consuming milk and milk products everday was higher in vitamin $B_2$ intake level than the other groups. Among dietary habits, the groups with good appetite and regular mealtime compared with the groups with low appetite and irregular mealtime had significantly higher nutrient intake levels. The family type was the determining factor of nutrient intakes. The subjects living with family members consumed higher nutrient intakes than the subjects living alone. The smoking and the alcohol consumption themselves did not affect nutrient intakes, but the subjects having alcohol consumption frequently more than once a day had lower nutrient intakes than the others. The group with dentures did not differ significantly from the without denture group in nutrient intakes; however, those who had chewing problems showed the lower nutrient intakes compared to those who did not have chewing problems. The subjects with more than two kinds of clinical symptoms had lower nutrient intakes than the subjects with less than two kinds of clinical symptoms. These results indicate that the identifying factors for desirable nutrient intakes of rural elderly were characterized as appropriate consumption frequencies of meat and fish, good appetite, living with family, regular mealtime, chewing without difficulty, and low incidence of chronic disease.

The purpose of this study was to investigate the pattern of individual fatty acid intake and to compare total serum lipid levels and total serum fatty acid composition of elementary school children in Seoul by fish and meat intakes. The subjects were divided into High-Fish / Low-Meat(HFLM, n=49) and Low-Fish/High-Meat(LFHM, n=47) group. The total energy from fat of HFLM and LFHM group was 22.0 and 30.0% respectively. The average intake of cholesterol was 237-287mg in HFLM group and 358-387mg in LFHM group. The average P/M/S ratio for all subjects was 1.1-1.4/1.1 - 1.2/1.0, which was very similar to desired ratio. The $\omega$6/$\omega$3 ratio of dietary fatty acids of HFLM and LFHM group were 8.0-10.9 and 18.9-29.3 respectively, which in case of LFHM group, was fat beyond the suggested range, 4/1 - 10.1. Serum lipid levels of all subjects fell within the normal range and there was no significant difference in serum lipid levels between HFLM and LFHM groups, except for HDL-cholesterol in upper grades(4th-6th grades). In lower grades(1st-3rd grades), serum PUFA composition of HFLM (40.8%) group was significantly higher than that of LFHM (38.3%) group (p<0.05) and SFA composition of HFLM(33.8%) was significantly lower than that of LFHM group, (p<0.001) between them. The $\omega$6/$\omega$3 ratio of serum fatty acid tended to be higher in LFHM than in HFLM group but there was no significant difference between two groups. This study suggests that the dietary fat pattern of growing children could affect the change in total serum fatty acid composition though it did not influence serum lipid levels significantly. Energy and EPA intakes were negatively correlated with HDL-cholesterol levels(p<0.05). Serum fatty acid compositions were more closely correlated with serum triglyceride(TG) levels than serum cholesterol levels. Especially, total SFA (p<0.001) and individual SFA, such as C14:0(p<0.001) and C16:0(p<0.001)compositions were positively correlated with serum TG levels, but stearic acid(p<0.01) was negatively correlated with it.

This study assessed yearly trends of food and nutrient intake among high school students aged 16 to 18 years (n=2,377) using the 2007~2015 Korea National Health and Nutrition Examination Survey (KNHANES). Yearly trends of food or nutrient intake were analyzed via logistic regression analysis. The results showed that consumption of sugars & sweets, and beverages & alcohols was increased rapidly during this period (p<0.0001). Intake of meat & meat products, and fish & shellfish also was increased (p=0.0008). Intake of grains and grain products was increased until year 2011 but declined after 2012 (p=0.0025). Consumption of vegetables, and milk & milk products was decreased (p=0.0395). Intake of protein, fat, thiamin, riboflavin, niacin, and iron was increased (p=0.0445). Carbohydrate energy ratio was decreased, whereas fat energy ratio was increased (p=0.0235). Most nutrient intakes satisfied the dietary reference intakes for Koreans except dietary fiber (19.6~26.2%), calcium (46.9~55.2%) and sodium (more than 221.4%) during this period. There was a significant positive correlation between most food group intakes and most nutrient intakes (p=0.0468). Therefore, it is crucial to increase dietary fiber and calcium intake and decrease consumption of sugars, fats and sodium through diverse eating of food groups to ensure balanced nutrition of subjects.

The purpose of the present study was to investigate the relationship between nutrient status, and bone mineral state which influenced by aging process. The subjects were 196 people over 65 years old(male 72, female124). The present dietary intake was estimated by the 24-hr, recall method, and individual dietary history concerning consumption of meat, fish and dairy products was obtained by questionaires. The syndrome of senility including seniliy was evaluated according to "Cornell Medical Index". The five subjects who showed 'Good' grade in bone senility, and five subjects who showed 'Risk' and 'Danger' grade were selected and their spine and femur bone density was measured by "Dual Photon Absorptiometry". The bone density measurement showed that the subjects with 'Good' grade in bone senility had bone density above that of normal person, and their nutrient status were satisfactory, whereas the subjects with 'Risk' and 'Danger' grade in bone senility had severe osteoporotic pattern, and their nutrient status were very poor. The food consumption score showed that the subject with higher intake of meat rather than milk had good grade in bone senility (p<0.05). Therefore, past meats consumption can be considered to be a significant factor in the present bone status. The nutrient intakes appeared to be significant factors in bone status in male, whereas there was little effect of nutrients intakes in female. Therefore, the risk of osteoporosis can increase as syndrome of bone senility and nutrient intakes were worse, and its is possible to evaluate bone status and predict osteoporosis simply from informations concerning syndrome of bone senility and nutrient intakes in old population over 65.

The purpose of this study was to investigate improvement of food habits and eating behavior in children with obesity and precocious puberty by nutritional education monitoring. The results are as follows. Average height and weight of subjects exceeded Korean height and weight standards for children as outlined by The Korea Pediatric Society. Using nutrition education monitoring, meals became more regular, overeating significantly decreased, and eating speed decreased. Further, frequencies of eating-out and night-eating significantly decreased. The most preferred menu item when eating-out was Korean food, and the most preferred menu item for night-eating was fruits, fast food, & processed food. Meat & fish and vegetable intakes all significantly increased. Fruit and milk intakes also significantly increased while bread, snack, and ice cream intakes decreased. Further, fast food & instant food intakes decreased. However, water intake was not significantly affected. The favorite food of children was meat & fish, followed by fast food & processed food. This study may provide information on dietary behavior of children with obesity and precocious puberty and suggests that nutrition education or counseling can improve food habits and eating behavior.

The purpose of this study was examine the health and food intakes of industrial workers who worked day and night. The questionnaire asked them about their health, stress, knowledge of nutrition, food habits, food intakes and frequency. The night-time workers had a stomachache compaired with day-time workers. Male day-time workers were more prone to stress than night-time workers in the area of job. In the areas of nutritional knowledge and food habits, there were no significant differences between day-and night-time workers for both male and female. Intakes of rice, bread, noddle, meat, fish. beans, vegetables in night-time workers were less than day-time workers. Also the male night-time workers consumed more milk and carbonated drinks than the day-time workers. The night-time workers were worse than the day-time workers and the female night-time workers were the worst. Considering the above results, the night-time workers should correct their food habits and have a well-balanced diet.

This study examined the effectiveness of two commonly used dietary assessment methods (the 24-hour recall and the food frequency questionnaire) in the epidemiological investigations of health-related habits and degenerative diseases. This cross sectional project in the Seoul area was conducted for the purpose of establishing cohort subjects and collecting reliable nutrient intake data for a further large-scale cross sectional study. The subjects were 91 volunteers from the Seoul area with a mean age of 53.5 \pm 9.6 for the males and 52.2 \pm 8.9 for the females. The subjects had a relatively high educational background, were from high socioeconomic levels, and were greatly concerned about healthrelated life styles. There was a significantly negative correlation between their smoking and their nutrient intake. Their drinking habits, their self-estimated health status and their concern or stress about being healthy did not have any influence on their nutrient intakes. Skipping meals was the most undesirable dietary habit influencing their nutrient intakes, and the next was their irregularity of eating meals. The subjects who liked legumes and fish had higher intakes of iron and niacin and those who liked milk and dairy products had higher intakes of calcium, vitamin \B_2 and fat. The subjects who considered themselves not to be healthy consumed higher amounts of fish and shell-fish, and those who considered themselves to be healthy consumed higher amounts of vegetables. The smokers consumed less fruits than non-smokers, but there was no correlation between their drinking and consumption of the food groups. There was no correlation between their food consumption frequency and their skipping meals or meal irregularity. There were positive correlations between their food likes and food consumption frequency for foods such as meat, milk and dairy products, seaweeds and fruits. Therefore, their smoking, skipping meals and meal irregularity appeared to greatly influence their nutrient intakes. Significant correlations were found between their health-related habits and their food group preferences and food frequencies. This implies that simple surveying methods using criteria such as smoking, skipping meals and meal irregularity, food group preferences and eating frequencies can be used as useful tools in the assessment of nutritional statuses.

The purpose of this study was to evaluate the effectiveness of nutrition education with nutrition services provided by dietitians who were placed in child care facilities from the Korean Dietetic Association. For this, we investigated the levels of nutrition knowledge and dietary intakes of children who attended child-care centers as well as dietary practices of children assessed by their parents. The treatment for children consisted of nutrition education and food service activities that are provided by the dietitian who have 3 to 5 years experience. Nutrition education was implemented during 10 weeks, 20 times, and a total 400 min and it's effectiveness was evaluated by questionnaire. Data were obtained for 123 children aged 4 to 5 years old who attended four child-care centers, one for a control group and 3 for intervention groups. Dietary intakes were investigated by measuring one-serving size and plate waste a of child for one-day dietary records before and after nutrition education. The levels of nutrition knowledge of children improved showing 70.80 points before to 83.45 points after nutrition education (p<0.001). Dietary intakes of the children after nutrition service increased significantly on cooked rice (133.66 g), Kimchi (19.41 g), side dish of meat/fish (48.40 g), and side dish of vegetables (24.88 g). Dietary practices of children after treatment also improved especially 'eat diverse meat, fish, egg, and bean' and 'never leave plate waste'. To summarize, this study pointed out that nutrition service and nutrition education provided by dietitians had influences on increases of the nutrition knowledge, dietary intake, and dietary practices. Therefore, placement of dietitians needs to extend to child care facilities from the 100 persons-over-capacity facility to the 50 persons-over-capacity facility, for providing professional service such as nutrition education and nutrition counseling.

The purpose of this study was to investigate the eating patterns, nutrient intakes, blood levels, and health status of male college students in Seoul according to body mass index (BMI). In this study, we classified subjects into normal weight (n=240), under weight (n=11), and obese (n=46) groups according to BMI. The weight and BMI were significantly higher in the obese group compared to other groups (p<0.0001). The obesity was associated with overeating and frequent eating. The under weight group showed significantly higher consumption of fast food, snacks, and fried foods compared to the other groups (p<0.05). The intakes of milk, meat, fish, eggs, and fried food and preference ratios were higher in the obese group (p<0.05). The male college students in this study showed insufficient intakes of calories, vitamin C, folic acid, and calcium. The plasma LDL-cholesterol levels in the obese group were higher compared to the other groups. In conclusion, intake of nutrients among male college students is found to be insufficient and requires nutritional education. The under weight group showed regular eating habits and increased nutrient intake. The obese group was shown to need more exercise with higher intakes of vegetables and fruits.

Two experiments were conducted with growing crossbred Super-Meat ducks at the experimental duck farm of Cantho University to evaluate the effects of reducing the proportion of soybean meal (SBM) in a broken rice (BR)-SBM mixture and providing soya waste (SW) ad libitum (Expt. 1), and reducing the proportion of fish meal (FM) in a BR-FM mixture and supplying ensiled shrimp waste (ESW) ad libitum (Expt.2). Both experiments included five treatments, with three replicates and ten growing ducks per replicate. In Expt.1, the five diets were based on BR and five levels of SBM, with SW offered ad libitum. The control diet (SBM25) consisted of 75% BR and 25% SBM, and the other four treatments included SBM levels of 20% (SBM20), 14% (SBM14), 8% (SBM8) and 0% (SBM0) mixed with BR to 100%, and with SW ad libitum. In Expt. 2, the control diet consisted of 86% BR and 14% FM, and the other dietary treatments had FM levels of 11% (FM11), 8% (FM8), 4% (FM4) and 0% (FM0) mixed with BR, and with ESW ad libitum. In Expt. 1, total intakes of dry matter (DM), neutral detergent fiber (NDF), acid detergent fiber (ADF) and metabolizable energy (ME) were higher for birds given SW (p<0.001). Total CP intake was highest on the SBM20 diet, and lowest on the SBM0 diet (p<0.001). Lower daily gain (DG) was found for the SBM0 diet (p<0.01). Carcass weights were higher on the control treatment, with the lowest values on the SBM0 diet (p<0.001). Gizzard weights were higher on diets with high intakes of SW (p<0.05). In Expt. 2, birds with high intakes of ESW (FM4 and FM0) had lower (p<0.01) daily intakes of DM. The total CP intakes declined (p<0.001) with higher intakes of ESW. The highest DG were for the control and FM11 diets, while the lowest value was for diet FM0 (p<0.001). The poorest feed conversion ratio (FCR) was for the FM0 treatment (p<0.01). Lower weights of carcass and breast muscle were found on the FM0 diet (p<0.001). Feed costs per kg gain were only slightly different between diets. However, the lowest feed cost was for ducks on the SBM0 and FM11 diets in Expt.1 and Expt. 2, respectively.
