This study was conducted to compare the dietary characteristics of middle-aged people with different obesity index or food habits. Questionnaires were collected from 480 subjects in Daejon. The data were analyzed by $X^2$-test and ANOVA. The subjects were distributed into the normal weight group(66.3%), overweight group(18.3%) and underweight(15.4%) based on BMI. Twenty-five percent of males and 23.0% of females in the 50＇s belonged to the overweight group. The least consumed food was milk or milk products among the five basic food groups. The frequency of exercise was low in their daily life. The had better food habits than the males. The overweight group had worse food habits than the normal weight or underweight group. The underweight group ate light meal and ate slowly. The better the subjects had, the more regularly they took breakfast(p＜0.001). The good food habits group were more interested in their dietary life and were more careful in selecting foods for their health than the bad food habits group(p＜0.001). Based on the results of this study, the practical education programs should be focused on more intake of milk or products and on daily exercise for the self-health maintenance of middle-aged people. Also, proper education programs should be developed for males and females in their 50＇s to practice weight control and regularity of meals in their life, and to utilize nutrition knowledge in dietary life. Further research on the comparision of dietary characteristics are needed with consideration of the subjects ratio according to BMI.

Findings from European and American studies have indicated such health behaviors as smoking, drinking, lack of exercise, and insufficient intake of grains, fruits and vegetables as risk factors for hypertension. However, because dietary pattern and health behaviors of Korean differ from people of other countries, the risk factors for Koreans could be different. Therefore, the aim of this study was to identify food consumption patterns and health behavior characteristics of Korean hypertensive adults. Data on food consumptions and other health behaviors such as smoking, drinking, and exercise together with development of hypertension were collected from 597 persons aged 20 to 69 years in a local community. The first stage of analysis utilized cluster analysis to aggregate individuals into different health behavior and food consumption groups. Four health behavior groups were characterized by passive cluster, smoker cluster, fitness cluster and drinker cluster. Food consumption patterns of the subjects were also aggregated into 4 different clusters: dairy cluster, grain & vegetable cluster, fruit cluster, and fish & meat cluster. Then univariate analysis was followed to identify the variables associated with hypertension. The final stage of analysis was the identification of the relative importance of the variables selected from the univariate analysis on hypertension, using multiple logistic analysis. The results showed that heavy drinking was the most significant health behavior associated hypertension, which was similar to the findings in European and American studies. However, unlike the findings from foreign studies, grain and vegetable consumption appeared to be a risk factor for hypertension. A possible reason for the contradictory results between Korean and Western studies may be the dependence of Koreans on white rice as the major staple food, and/or the frequent consumption of salted vegetables, rather than fresh vegetables as is customary in Europe and America.

This study was carried out to investigate the difference of the body image recognition, food habits, food behaviors and nutrient intake according to the obesity index(underweight-, normal-, obese group) in children(aged 10.8 ys, 47 boys, 33 girls). Subjects were eva1uated based an anthrofometric measurement and questionnaries including food record diary in Changwon. The results are summarized as follows. The weight, BMI, body fat, waist circumference, hip circumference and birth weight except height showed a significant difference between the three groups(p<0.001). The waist and hip circumference showed the possibility of being a predictor of obesity in children. The children's obesity was related to mother's weight(p<0.01), but not to father's. Ninety percent of the obese group, 47.8% of the normal group, and 37.8% of the underweight group preferred a thinner figure than their current status. The underweight group did more exercise regularly than the other groups. The underweight and obese groups had more irregular meal times and foster eating habits compared to the normal group. Most of subjects(89.9%) had an overeating habit, and tole ratio of the overeating habit increased with obesity. Fifty five percent of the subjects clad the habit of skipping meals, mainly breakfast. 46.8% of the subjects ate snacks more than twice per a day, the underweight and obese groups had snacks more of than the normal group. The preferred snack was 'cookies'and 'fruits ＆ juices'. 53.8% of the subjects had a prejudice for special food(especially 'pulses'(37.9%) and 'vegetables'(31.0%)). The assessment scores of food behaviors was relatively low in most of the subjects. Most nutrient intakes, except vitamin B$_1$, C and phosphate, were lower than those of Korean RDA. The nutrient intake of the normal group was higher than the underweight and obese groups. The results of this study showed some nutritional problems, which indicates the need for nutritional management for the children. To educate children, who are able to change their food habits and lifestyle, each means to help healthy growth and to help them become healthy adults.

This study was performed to determine the effects of dietary calcium (Ca) intake, milk and dairy product intake, and serum vitamin D level on bone mineral density. The survey data from the 2008-2009 Korea National Health and Nutrition Examination Survey (KNHANES) for adults (3,819 males, 5,625 females) aged > 20 years were examined; osteoporosis was defined according to the standards for Asian populations (T-score < -2.5). The risk for osteoporosis significantly decreased as Ca intake increased; this effect persisted (quartile 4 vs. quartile 1 of Ca intake: odds ratio [OR] 0.66; 95% confidence interval [CI]: 0.50-0.87) even after adjustment for gender, age, and other factors (body mass index, serum vitamin D, menstruation, female hormone intake, menopausal status, and the number of days per week of muscular strength exercise). Additionally, the risk for osteoporosis significantly decreased as the Ca/P ratio increased (quartile 4 vs. quartile 1: OR 0.76; 95% CI: 0.58-0.98). The degree of risk was 0.96 (0.66-1.38) in those who consumed < 1 portion of milk or dairy products daily, and 0.71 (0.53-0.96) in those who consumed > 1 portion per day, compared with those who had zero intake. The risk for osteoporosis significantly decreased as the serum 25(OH) vitamin D level increased. From these results, we advocate an increase in Ca, milk, and dairy product intake, and that serum 25(OH) vitamin D levels be maintained within the normal range, for the maintenance of bone health and the prevention of osteoporosis in adults.

The purpose of this study was to provide the basic information on nutritional condition for improving performance of the national junior rowing team players(male n=17, female n=14). To attain this purpose, their body composition and energy intake situations were investigated during their three-week winter training camp. Measurement of body composition measured by the interval, and two days, and dietary intake in this study to investigate the type and amount of food, the researchers measured directly, and then refer to the record subjects to investigate the dietary intake and the adoption of a Weighing Method. The result is as follows. During training, body composition due to the high intensity training to maintain a properly balanced diet is the consumption of energy, weight and body composition has a positive influence. The male players' average energy intake is 5,951.6 kcal(72.6 kcal/kgBW, 150%), the rate of the three main nutrients, carbohydrate, fat, protein, is 72.6 : 8.7 : 18.7 respectively. For the female, the average energy intake is 3,685.6 kcal(51.8 kcal/kgBW, 121%), and the rate of the three main nutrients is 76.3 : 8.5 : 15.2. Both of male and female were taken sufficient Vitamin, mineral and other nutrient according to %RI(recommended intake). Based on the results of a survey of elite athletes and nutrition management and the systematic introduction and review of the program in conjunction with a professional nutritionist would need, and can also be applied to expand the school to the scene, the reality of the program review and development of qualified need.

This study was directed to further clarify the effect of resting time or dietary condition for the improvement of exercise capacity and physical fitness, and the changes of some body consitiuents and physiological functions which are related to the exercise metabolism. Sixteen male students(8 athletes and 8 nonathletes)were participated during 3 weeks(Aug. 20-Sep.9, 1989). Each subject performed two treadmill running trials at an absolute intensity (1 mintute in 3.4mph/15% slope and 2 minutes in 5.5mph/20% slope). In the resting time trials, general diet was fed before 1, 2, 4 and 12 hours of the treadmill exercise loaded. in the dietary condition trials, high carbohydrate(HC), high fat(HF) and high protein(HP) diet were fed before 2 hours of the treadmill exercise loaded. Control trial was that of resting time before treadmill exercise loaded after 12 hours of general diet feeding. Measurement were made to study the change of blood glucose, palmitate, lactate, blood pressure and heart rate. The results obtained are summarized as follows: Mean daily metabolizable period. In resting time trial, the blood glucose concentration of athlete and nonathlete from 2 hours group was similar to control group. The blood palmitate concentration of athlete was increased in 1 and 2 hours group but those of nonathlete was not only increased in 1 and2 hours group but was more increased in 12 hours group, compared with both control group. The blood lactate concentration was increased in all experimental group, compared with both control group and those of nonathlete was much higher than athlets. The elevation rate of blood pressure in pre-and after-exercise of athlete was lower than those of nonathlete. In dietary composition trial, the blood glucose concentration of athlete and nonathlete in HC group was higher than other diet groups. The blood lactate concentration of athlete and nonathlete in HC group was lower than other diet groups. There was no remarkable change of the blood palmitate concentration and heart rate in each dietary composition trial, but those of nonathlete was low in HC and high in HP group. In above results, it was suggested that the effective condition of resting time and dietary composition for the improvement of exercise capacity of nonathlete may be 2 hours and HC diet, respectively. But it was showed that the exercise capacity of athlete may not be affected by experimental condition of resting time, except 1 hour after feeding or of dietary composition because of well adaptation in new exercise condition.

The purpose of this study was to describe the way of life (such as smoking habits, alcohol consumption, exercise, duration of sleep, eating habits etc.), physical. psychological and overall health complaints and to identify the relationship between the way of life and health complaints of the nursing students. Data was collected with the self-administered OMI( Okayama Medical Index Health Questionnaire, devised Cornell Medical Index) from 766 nursing students and was analyzed. For data analysis, descriptive statistics and an ANOVA with an SPSS/PC+ program were used. The results were as follows: 1. The mean age of subjects was 21.0557(2.7618) years old in their 1st, 2nd, 3rd and 4th year-classes of nursing departments and college students in 4 regions of Korea. 62.1% of subjects were of the proper body weight, 2.0% were overweight, and 28.3% were underweight. Most subjects did not have a past history of disease, but 1.8% of subjects had experienced a blood transfusion. 2. 28.3% of the subjects had averaged 7 hours of sleep, 98.5% were nonsmokers, 91.2% were nondrinkers, 74.7% of subjects had milk intake sometimes, 53.7% of the subjects had an average salt intake, 49.6% of the subjects usually had a green vegetable intake, 45.4% of the subjects sometimes had fatty food intake, 64.8% of the subjects had good taste, 29.5% of the subjects enjoyed physical exercise. 3. The highest percentages of 'yes' among physical. psychological and overall health complaints were observed in the question 'Do you have gastric pain?'(60.2%), 'Are you confused of disorderly?' (37.2%), 'Physical body was burdensome and fatigued.'(57.3%). 4. The total O.M.I. score ranged from 1 to 89 with an average of 22.91(SD=12.10). A statistically significant difference was observed for the physical. psychological complaints for alcohol consumption. and for the psychological complaints for salt and fatty food intake. These conclusions should provide grounds for future studies of strategies for health promoting lifestyle for nursing students and their health concerns. Further research is required to investigate the life environmental and psychological factors affecting the way of life for nursing students and their health status, to analyze the health behavior of nursing students related with their culture and consciousness. Also epidemiologic research methodology, such as prospective cohort study should be considered to explore the performing process of nursing student's health behavior related with the occurrence of diseases.

This study seeks to classify the skin types and determined the relation between the dietary habit and preference of foods targeting college women in Daegu and Gyeong-Buk Province. Skin types of the subjects were 31% of combination skin, 25% of dry skin and 22% of normal, oily skin. College women mostly had two meals a day, and those who had less frequent meals developed more combination skin. Many of them did not exercise, and women with normal skin who did not exercise showed the lowest at 13.9%, supporting the significance (p<.05). It was exposed that don't have breakfast and have irregular meal and don't have easy meal in all skin types. Instant foods was exposed that ingested the most in dry skin and the least in oily skin, supporting the significance(p<.05) and fruit or vegetable ingested much in dry skin. It was exposed that considered atmosphere at meal and meal helps in health in all skin types, normal skin type considered balanced diets the most and supporting the significance(p<.01) Food preference in all skin types showed the strongest in drinks and showed strong in greenish yellow vegetables, fruits, confectioneries, drinks, milk and dairy goods. On the other hand, it showed low in nuts and salted fishes. In sum, regular and balanced meals give the skin a healthy status, and intake of protein, vitamins and minerals has impact on the skin status. Thus, sufficient quality nutrition is crucial in staying a healthy skin.

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.

This study was conducted to obtain principal data on nutrition education according to college major after analyzing the nutrition status of 302 male university subjects. The 302 male subjects consisted of male students majoring in literature and science (109), food and nutrition (94), and physical education (99). Exactly 47.9% (highest among the groups) of male students majoring in food and nutrition ate regular meals, 39.4% ate breakfast. Precisely 29.4% of subjects majoring in literature and science never ate out. Exactly 23.2% of subjects majoring in physical education over ate frequently, and 31.3% enjoyed eating out. Intakes of protein, fat, vitamin A, $B_1$, $B_2$, $B_6$, C, E, folic acid, Ca, Fe, sodium, and cholesterol among male students majoring in food and nutrition appeared to be significantly higher compared to those of other groups (p<0.05). Intakes of energy, Zn, dietary fiber, and cholesterol among male students majoring in physical education were higher, whereas intakes of all nutrients except for dietary fiber by subjects majoring in literature and science were lower than the other two groups. Exactly 20.2% of male students were interested in health. We found that 52.4% of subjects considered exercise as an important factor for maintaining health. Smoking rate was the highest (43.6%) among male students majoring in nutrition, and the drinking rate was highest (56.0%) among male students majoring in literature and science. We found that smoking was continued as a habit (61.5%) while drinking was essential for social relationships (73.9%). From this study, it was found that male students have problems associated with eating regular meals, skipping breakfast, overeating, and intake of unbalanced foods. Also, male students who majored in food and nutrition demonstrated problems in applying their knowledge to proper dietary habits. In conclusion, a systemic educational program needs to be introduced to promote healthful dietary habits in male students.
