This study was carried out to examine the effects of alcohol on serum lipid levels. Subjects of this study were 50 military officers living in Honsung, Korea, 25 of whom consumed alcohol on a regular basis and 25 of whom did not. All subjects were previously informed of the purpose of the study and the methods of food intake reporting and blood testing. The age distribution range of subjects was 30-49 years. Weight, height, and body mass index(BMI) were not significantly different between the two groups. Blood pressure was compared, and it was found that the drinker group had mean systolic(SBP) and diastolic blood pressures(DBP) 10mmHg higher than the non-drinker group. Nutrient intake levels of the two groups were not significantly different and were adequate with respect to the recommended dietary allowances. It was found that the drinker group ingested more calories, protein, fat and vitamn B1 than the non-drinker group, while the non-drinker group ingested more carbohydrate, calcium, iron, vitamin A, niacin and ascorbic acid. These differences were believed caused by increased caloric intake from alcohol and additional intake of meat served with drinks for the drinking group. Fourteen of the twenty-five drinkers(56%) had drank regularly for five to ten years. Most drinkers drank 2-3 times per week, with alcohol intake less than two bottles(720ml)of distilled liquor(Soju) at a time. Meat was often served with alcohol as reported by 72% of the drinker group, and was believed to contribute to raised intake of calories, protein and fat in this group. Serum lipid levels of both groups were classified as normal, but the components of total cholesterol, triglycerides were significantly higher in drinkers than non-drinkers. The correlation between triglyceride levels and alcohol intake at one sitting was shown to be significantly positive(r=0.57, p<0.01), so it was believed that triglyceride elevation was associated more with heavy drinking than light drinking. We can conclude that if alcohol is consumed with a normal diet, then serum cholesterol, triglyceride and total lipid levels are expected to increase.

This research was conducted to evaluate the general dietary quality(the balance and diversity of food intake, nutrient intake and adequacy) of 12 to 36-month-old toddler, through examining their actual food intake. It was conducted for 664(male-357, female-307) healthy toddler who were outpatients from Mar. to Aug., 1999 at university hospitals and private hospitals in Seoul and kyunggi province. The anthropometric parameters were measured. The 24-hr recall method were utilized to analyze the nutrient intake by months, based on the classification of The Korea Child Gorwth Standard. As for the subjects of this research, we found that the younger the age, the more frequent the pattern of intake of only 3 kinds of food groups. The results are that 1) the group with 1 point of the DDS(Dietary Diversity Score) mostly took only foods from the milk group, 2) the group with 2 points only took foods from the grain and milk group, 3) the group with 3 points did not take foods from the fruit and vegetable group, and 4) the group with 4 points took just about all kinds of food groups except for the vegetable group. This means that most of them were not taking various kinds of food even after the age of 12 months, and that they took more than twice the recommended amount of foods from the milk group until the age of 20 months. Thus, one could find a tendency of dependance on the milk group for food intake. Food intake for the vegetable group was severely under the recommended allowance, regardless of the age. The intake of iron was less than two thirds of the recommended allowance, except for the group of 12 to 14-month-olds who had been fed with infant formula. The Nutrient Adequacy Ratio(NAR) of major nutrients(protein, calcium, phosphorous, iron, vitamin A, vitamin B$_1$, vitamin B$_2$, niacin, vitamin C) and the Mean Adequacy Ratio(MAR, shows the general quality of dietary intake) was 0.86$\pm$0.12, but the NAR of iron was 0.62$\pm$0.27, which was extremely low compared to those of other nutrients. Therefore, concerning the subjects of this research, the MAR value alone does not provide enough ground to conclude that the subjects dietary quality is satisfactory.

This study was conducted to examine bone mineral density and factors which effect on bone mineral density such as daily nutrients intake, age, menarch age and physical condition among healthy female college students in Daegu area from April 20, to May 20, 2004. 1. Average age was 20.5$\pm$0.96 years old, average height was 160.9$\pm$4.30㎝, and average weight was 55.9$\pm$7.67㎏. Body mass index was 21.6$\pm$2.91㎏/㎡, body fat was 25.6$\pm$5.79％, menarche age was average 12.5$\pm$1.1 years old and WHR(waist/hip circumference ratio) was 0.8$\pm$0.01㎝/㎝. 2. Average level of bone mineral density(T-score -0.56$\pm$0.91) was in normal range. But, 11 persons(24.4％) are over T-score -1.0, 33 persons(73.4％) were within -1.0 - -2.5 and one person(2.2％) was under -2.5. It is very anxious level for Osteopenia-low bone mass, as research result shows 73.4% of the subject of examine on the level of Osteopenia. 3. Daily calorie intake was 2,550㎉ and each nutrient intake, compared to the seventh recommended dietary allowances for korean, was as follows ; Calorie 112％, protein 123％, calcium 78％, phosphorus 137％, iron 68％, vitamin A 101％, vitamin $B_1$ 141％, vitamin $B_2$ 95％, niacin 107％, vitamin C 128％ and zinc 120％. The ratio of calcium to phosphorus(Ca/P) is 0.66, low compared to RDA, but phosphorus intake is so high compared to RDA that precautions should be taken. The ratio of calcium to protein(Ca/Protein) is 8.55. 4. Menarche age and bone mineral density of calcaneus showed positive correlation and body mass index(BMI) indicated positive correlation. Age, height, weight. WHR and physical activity coefficient all do not indicate any significant correlation with bone mineral density. 5. Intake of Calorie, Ca, Ca/p ratio, carbohydrate and fat intake were positively correlated and, protein was negatively correlated, and Fe, Na, P and cholesterol were negatively correlated with BMD. These results indicate that average bone mineral density of subjects was in normal range, but subjects in the stage of osteopenia-low bone mass are many and bad effects are expected to have on their bone mineral density after menopause. Therefore, in order reach maximal bone mineral density, they should improve the balance between calcium and phosphorus and reduce salt intake. And it is thought that education and profound studies on relevant factors affecting the genesis of bone mineral density should be made.

The main purpose of these studies was the improvemen of nutritional supply and of the future physical coditions. The two groups which were regional difference were chosen and research for the nutritional status of elementary school students. The nutritional status of lunch-box between one elementary School of 98 students in the 6th year grade(hence-forward it was called "A-Group"), located at the center of Masan City, being provided the milk and the other elementary School of 134 students in the 6th year grade(hence-forward it was called "B-Group"), located in the small farm and fishing villages of Kusan-myun, Euichang-kun, Kyungnam province, were seweyed from the period of Nov. 20, 1986 to Dec. 4, 1986 and conclusion were as follows: 1. Nutritional status of lunch-box 1) It is indicated that in the case of A-Group, the nutirtional intake except animal protein and vitamin A were lower than the Recommended Daily Allowances of Korenas and in the case B-Group, was also lower than except vitamin A respectively and especially in both groups, the percentage of Fe was lowest and intended difference between A Group and B was that B-Group in the intake of calorie, fat, Ca, Fe and etc were lower than A-Group. 2) The total calorie-intake was short of the extent to approx. 83.8% as compared to the RDA. On the viewpoint at ratio of intake of caloric nutrients, A-Group appeared to be 69.5 : 16.5 : 14 and B-Group, 77.5 : 19.5 : 13 in order carbohydrate, protein and fat. As a result of the above ratio, B-Group depended upon carbohydrate as a staple food more than A-Group. It can be considered that the total calorie-intake is short, and that the amount of lunch-box was greatly insufficient for taking optimal nutrition. 3) Calorie, carbohydrate, vitamin B, and niacin were taken nutrition from a staple food and protein from at similar ratio of staple and subsidiary food and fat, Fe, vitamin A, vitamin B1, adn vitamin C were mainly taken from a staple food. It was indicated that B-Group was higher at the supply-ratio by a staple food than A-Group. 3. The realities of improvement of physical conditions The improvement of physical conditions of the two groups were lower in accordance with Korea Children's Growth Standard, but B-Group was inferior to A-Group. 4. Seeing that the total intake of nutrition being taken at lunch time was lower as campared to the RDA intakes between the two Groups were remakably different, a lot of efforts should be made to improve the calorie-intake for the purpose of the farm and fishing villages. For balanced intake of nutrition, selection of foods and various cooking ways are important, therefore, throughout the expansion of the lowest stratum of elementary schools for milk-supply, high-quality protein, fat, Ca, vitamin B2 and etc should be supplied to the growing students. That can narrow the gaps of the intake of nutrition and physical condition between the students who live in cities and the students who live in the country.

This study was undertaken to investigate iron status and related factors in female college students residing in Gyeongnam. The subjects were divided into normal (40.8%) and iron deficiency (ID) groups (59.2%) by iron status. Mean height, weight, lean body mass, percent body fat, body mass index, and wrist to hip ratio were not significantly different between the groups, but basic metabolic rate was significantly higher in the normal group than that in the ID group. The levels of hemoglobin, hematocrit, serum ferritin, transferrin saturation, mean corpuscular volume, mean corpuscular hemoglobin, and mean corpuscular hemoglobin concentration were significantly higher in the normal group than those in the ID group. However, total iron binding capacity was significantly lower in the normal group than that in the ID group. Daily intake of protein, heme-Fe, niacin, and vitamin C were significantly higher in the normal group than those in the ID group. The mean intake of protein, Fe, niacin, vitamin $B_{12}$, and vitamin C based on the Korean recommended intake (RI) were significantly higher in the normal group than those in the ID group. The mean intakes of Ca, vitamin $B_{12}$, and folate in both groups were < 75% of the Korean RI. In conclusion, increasing dietary heme-Fe and vitamin C may be helpful for preventing ID anemia in female college students.

This survey was carried out to obtain the information concerning nutritional status, including factors of food intake and health condition of elderly women living in Ulsan city. Main results were as follows. 1) Dietary intake data showed the average daily intake of energy, protein, vitamin A, riboflavin and ascorbic acid were lower than Korean recommended dietary allowances (RDA). According to the percentage of RDA, Vitamin A was the nutrient found to be least sufficient. 2) Among the various influencial factors, pocket money, meal-mate, skip meal and health concern influenced on nutrient intake considerably. A meal condition score based on influencial factors, showed significant correlations with all nutrient intake(P<0.001). A health score based n the subjects complains about health condition, showed significant correlations with intake of energy, carbohydrate, thiamin, and niacin(P<0.05). 3) Average hight was below Korea reference, while average body weight of subjects was close to Korean reference. Average body mass index was 23.0. 4) The average systolic and diastolic blood pressure was 140mmHg/88mmHg, the proportion of hypertension was 32.4 percent. The average hemglobin concentration was 12.7g/dl, only 6.7 percent of subjects were anemic. Serum cholesterol concentration was normal range(140~220mg/dl) in all subjects.

The purpose of this study was to investigate the relationship among nutrient intake, life style, and serum lipids level in 108 healthy middle-aged men in Taegu. A convenient method was to assess nutritional intake. Anthropometric measuement of body weight and hight were measured and average energy expenditure was calculated. The mean body mass index(BMI) was 22.8$\pm$2.4 and it was in the middle of the mean BMI of Korean men. Obesity rate of study subject were 13.2%. Daily energy intake was not sufficient as 88.4% of recommended dietary allowances and the energy percentage of carboydrate, fat protein was 65 : 21 : 14. Mean intake of vitamin A, B1, C and Ca were lower than RDA. There was a highly significant negative correlation between the systolic blood pressure and calcium intake(r=-0.28, p<0.05). Smokers showed significantly higher blood glucose than non-smokers. Skipping meals and uneven diurnal distribution(no breakfast and large evening meals) are associated with high triglyceride level in this population. There was a highly significant correlation between body weight and plasma lipids. Energy expenditure was negatively correlated with plasma triglyceride level. Especially, atherogenic index was significantly lower in job-time physically active worker than that in sedentary worker. Above data provides valuable imformation to the community for program planning as well as to health providers who work individual male adults to meet their nutrition needs and to control blood lipids.

To assess the dietary fiber intake of preschool children in Busan and to evaluate the relationship between of the intake of dietary fiber and nutrient intake. Nutrient intake using 24 hour recall, and total dietary fiber (TDF) intake based on tables of TDF of common Korean floods developed by the modified Prosky Method, were estimated for 176 preschool children. The mean daily intakes of TDF, and TDF after adjusting energy intake, were 10.20 g and 7.69 g/1,000 kcal, respectively. The mean daily intakes of TDF for children aged 1-3 and 4-6 years were 9.20 g and 11.08 g, respectively. The range of TDF intake was 1.86 to 22.16 g. The major sources of TDF were cereals (31.0%), vegetables (18.9%) and fruits (11.9%). The TDF intake showed positive correlations with nutrient adequacy ratios (NAR) of iron and Vitamin $B_1$, (p < 0.05, p < 0.05). The TDF intake per 1,000 kcal showed negative correlations with the NARs of protein, calcium, phosphate, iron, Vitamin A, vitamin $B_1$, Vitamin $B_2$, and niacin (p < 0.001, p < 0.001, p < 0.001, p < 0.05, p < 0.001, p < 0.001, p < 0.001, p < 0.001) and with the mean adequacy ratio (MAR, p < 0.001). When children were stratified into quartiles ($Q_1-Q_4$) on the basis of their fiber intake per 1,000 kcal, their NARs for calcium, phosphate, iron, Vitamin A, Vitamin $B_1, Vitamin $B_2$ and niacin (p < 0.05, p < 0.05, p < 0.001, p < 0.05, p < 0.05, p < 0.001, p < 0.001), and their MAR (p < 0.001) were significantly lower in the children with higher fiber intake per 1,000 kcal (the upper quartile). The NARs fur calcium (0.63), iron (0.60), Vitamin A (0.66), Vitamin $B_2$(0.74), niacin (0.64), Vitamin C (0.65) and the MAR (0.74) were lower than 0.75 in the children with fiber intakes of more than 9.25 g per 1,000 local (0,), the highest fiber intake per 1,000 kcal. Based on these results, the mean TDF intake of children was higher than the age (yr)+5g , the minimum recommended level for American children. Meals with a fiber intake of more than 9.25 g per 1,000 local ($Q_4$) could cause a decreased nutritional status for minerals and vitamins. The result of this study could contribute to the establishment of Recommended Dietary Allowances (RDA) for dietary fiber for Korean Preschool children.

To assess the dietary therapy compliance of non-insulin-dependent diabetes mellitus (NIDDM) patients living in Daegu, we evaluated diet adequacy levels by index of nutritional quality (INQ), nutrient adequacy ratio (NAR), mean adequacy ratio (MAR), and dietary variety score (DVS) with food exchange system and Korean recommended dietary allowances (KRDA). One day dietary intake was measured by 24 hour recall method for 229 subjects over 20 years of age. Average daily energy intake was 1444 kcal. The relative ratio of carbohydrate, protein and fat in terms of energy intake was 69.4：14.5：16.0. The nutrient adequacy ratio (NAR) for Vitamin A, B$_2$, calcium were lower than 0.5 and MAR was 0.65. It appeared that the consumption of each food group as compared to prescribed food exchange unit was insufficient, in the order of dairy group (10.2 $\pm$ 25.2%), fruits group (58.2 $\pm$ 71.2%) and oils & fats group (42.9 $\pm$ 42.0%). The dietary variety score (DVS) was evaluated as an useful tool for diabetes' meal management when we accept minimum intake as 0.3 of food exchange unit. We found significant correlation between food groups and anthropometric indices: cereals group and % total body fat (r = 0.251, p < 0.01), meat group and waist circumference (r = 0.241, p < 0.01), vegetables group and WHR(r = 0.139, p < 0.05), and oils poop and WHR(r = 0.165, p < 0.05). from these results, we concluded that overall status of dietary intake of NIDDM patients in Daegu area was insufficient not only in quality but also in quantity. It is suggested that nutrition education for NIDDM patients should stress on balanced food consumption to meet proscribed amount by six food group to improve the inadequacy of dietary status.
