This study was conducted to examine the nutritional knowledge and dietary habits by gender and a mother's employment status for middle school students. The subjects consisted of 423 students (212 boys and 211 girls). As for mother's employment status, 61.7% of the mothers were working, and 38.3% were housewives. The results from the analysis on differences of nutritional knowledge and dietary habits showed that girls tended to have a higher nutritional knowledge than boys (p<0.01). In terms of dietary habits, boys appeared to have more desirable eating habits than girls. As for the mother's employment status, only students whose mothers were doing housework tended to have higher nutrition knowledge and more positive dietary habits than students whose mothers were working. The influence of nutritional knowledge was found to have a significant effect on dietary habits (p<0.001). In addition, nutritional knowledge (B=0.168, p<0.01) turned out to have an influence on dietary habits, where a higher nutritional knowledge produced more positive dietary habits. Considering the results described above, nutritional knowledge appears to have a significant influence on dietary habits. Therefore, instructions on the importance of nutritionally well balanced meals must to be reinforced in nutritional education.

The purpose of this study was to survey the concern for health, nutrition knowledge, and nutritional attitude of the elementary school children's mothers, to investigate the correlations among them, and to estimate their effects on the growth of their children. The questionnaire was answered by 780 mothers in the Busan area. The concerns over health and nutritional attitude were above average in all items. The perception and accuracy with respect to nutrition knowledge were 90.3% and 77.0%, respectively, and the mean score of the nutrition knowledge was 17.5 on a basis of twenty-five. This indicates that the subjects had a comparatively deep concern for health and good knowledge of nutrition, and professed a relatively desirable attitude. These results indicate a desirable dietary attitude for children as well as parents. The correlation coefficients between nutrition knowledge and a concern for health, and between nutrition knowledge and nutritional attitude were very low. This suggests that the subjects' knowledge of nutrition does not develop into practice. The correlation coefficient was high (r=.610) between the concern for health and the nutritional attitude. In conclusion, the nutrition education program for mothers should be developed to add good practice to knowledge, thus increasing the concern for health, correcting their faulty knowledge of nutrition, teaching the good nutrition, and taking a practical attitude toward the use of their present nutritional knowledge.

Malnutrition is a common problem in patients undergoing maintenance hemodialysis(HD) and compromised food intake is an important cause. Malnutrition is one of the important factors influencing mortality in chronic HD patients. We investigated the nutritional parameters of 50 Korean HD patients(mean age: 46.9 $\pm$ 10.3y, men : 23, women : 27) by measuring anthropometric and biochemical blood indices and assessing food intake using 24-h recall method. Also we administered two questionnaires, one for assessing nutritional knowledge about renal disease and dietary therapy, the other for measuring dietary habits related to dietary therapy. According to the distribution of BMI, 21.3% of HD patients were underweight. The hematological values of HD patients, such as plasma hemoglobin, hematocrit, and total lymphocyte count were below the normal range. The serum cholesterol levels were 133.2 $\pm$ 30.5mg/dl. HD patients took energy and protein only 77.5% and 83.1%, respectively, of their RDA. There were significantly positive correlations between nutritional knowledge and intake of nutrients, such as energy, fat, cholesterol, iron, potassium, vitamin B$_1$, vitamin B$_2$, and niacin. Also, there was a significantly positive correlation between nutritional knowledge and dietary habits(r = 0.317, p < 0.05). In conclusion, Korean HD patients showed mild malnutrition and suboptimal nutrition intake. It can be postulated that the dietary intake can be increased by nutrition education improving nutritional knowledge and correcting the dietary habits of HD patients.

The purpose of this study was to investigate nutritional risk factors, perceptions on nutrition and health, nutritional knowledge, flood habits and their correlation to supplement use in middle-aged and elderly Koreans. A nationwide survey was conducted in the metropolitan areas (6 cities) and middle-sized cities (8 cities) of Korea from October to December, 2000. Subjects were randomly selected based on population, and 2,188 non-institutionalized adults aged over 50, and elderly (male 765, female 1,423) were studied. Data were collected using a standardized questionnaire administered in personal interviews. Nutrition and health-related scores of nutritional risk factors, perceptions on nutrition and health, nutritional knowledge, and flood habits were significantly higher in supplement users as compared to non-users. There was a negative correlation between nutritional risk factors and other nutrition and health-related scores on perceptions on nutrition and health, nutritional knowledge, flood habits, and pocket money. Also there was a positive correlation between nutritional risk factors and age. Therefore, these results may provide basic information for proper supplement use by middle-aged and elderly koreans.

This nutritional survey was conducted from February 8 to March 10, 1994, in order to investigate the nutritional knowledge, food habits, nutritional attitude, food preferences and nutrient intakes of urban middle-aged women living in Daegu and Pohang district. The subjects of this survey were 164 urban middle-aged women living in Daegu and Pohang Area. The completely answered questionnaires were analyzed for nutritional knowledge, food habits, nutritional attitude, food preference and nutrient intakes of urban middle-aged women. The results obtained are summarized as follows: The subjects had a high level of perceived knowledge (82.9%), that is the knowledge that each subject believed she had, but the accuracy of the knowledge was only 66.1%. The average nutrition knowledge score was 8.26 out of possible 15 points, and food habit score was 5.50 out of 10 points. Most of the subjects belonged to 'Fair' or 'Good' food habit group, which is considered to be relatively good. With increasing age, the percentage of perceived knowledge, accuracy, and nutrition knowledge score were getting lower. But food habit score and nutritional attitude score were getting higher at 40's women than 30's women. The correlation between nutritional knowledge score and food habit score was low (r=0.0748). The correlation between nutritional attitude score and food habit score was low, too (r=-0.0653). Food preferences for kimchi, potato, cooked rice, beef, noodle, cabbage and milk were high. Average calorie and protein intake of the subjects were $1967.4{\pm}27.8\;Kcal$, $75.8{\pm}1.4\;g$ respectively. Carbohydrate, protein and fat ratio on energy composition was 63.3%:15.5%:21.2%.

The purpose of this study was to investigate dietary habits, dietary attitudes, perceptions for nutritional importance, nutritional knowledge and frequency of food intake to get the basic data of effective nutritional knowledge to form desirable dietary habits of students. This study was carried out through a questionnaire. The subjects were 362 teenagers (boys 161, girls 201) in some farming and fishing regions of Jeonnam. The most desirable dietary habit was that both boys and girls never skipped their lunch, the undesirable dietary habit was that boys ate too fast and girls had too many snacks. While boys ate faster than girls (p < 0.01), girls skipped dinner more frequently than boys (p < 0.01). In terms of dietary attitudes, boys had more desirable attitudes than girls in that they "choose nutritious food" (p < 0.01), "enjoyed healthy food more than favorite food" (p < 0.01), "think about basic food groups when having something" (p < 0.01) while girls had more desirable attitudes than boys in that they "only have favorite food" (p < 0.01). In nutritional knowledge, girls showed a percentage of more correct answers than boys in "is likely to suffer anemia without enough iron" (p < 0.05), and "it doesn't need to eat fat, which causes obesity" (p < 0.05). In general, girls had higher nutritional knowledge than boys. For frequency of food intake, boys ate more fried and broiled food than girls (p < 0.05). In general, boys had nutritional unbalanced diets more than girls. As a result, girls had higher levels of nutritional knowledge and boys had more desirable dietary habits and attitudes. We should have systematic and repetitive education about nutrition so that teenagers could practice their nutritional knowledge in diets. Moreover, it is necessary to develop proper education for their genders.

This study was to investigate the children's understanding level of nutritional knowledge and the degree of knowledge application into the actual living not only in the with-lunch school but also in the without lunch school. Having expected their obtaining of nutritional knowledge and practical applicating, we compared the with-lunch school children's understanding level of nutritional knowledge, dietary attitude, and completeness of diet life with those of without-lunch school children. In addition to this, we surveyed healthiness, Physical condition, and BMI (Body Mass Index) and compared these factors. The results are as follows. 1. Almost all of the children were standard in physical condition, however they recognized themselves fatty than normal. Mealtime consumption(p＜0.05), BMI(p＜0.05), and diet attitude points(p＜0.001) showed significant difference in the children who regarded the themselves healthy. 2. High correlation was observed between parent's physical shape and mealtime consumption (p＜0.05), quantity of eating food (p＜0.001), children's BMI(p＜0.001) and diet attitude(p＜0.05) respectively. 3. The points of itemised nutritional knowledge test was different in accordance with the children's year grade (p＜0.05), children's understanding level of health and physical condition(p＜0.05), parent's physical shape (p＜0.05), and mother's education level(p＜0.05) respectively. The points of nutritional knowledge test in both schools showed no difference except the item of vitamin.

Osteoporosis is a major health problem confronting middle-aged women today. Enhancing calcium intake in early adulthood can increase the rate of calcium gain in bone. In this study, we investigated the association of bone health-related nutritional knowledge levels with calcium-related dietary behavior and nutrition education among women. Data were collected using questionnaires from 347 women aged 20~30 residing in Gyeonggi-do. Subjects were categorized into two groups according to their bone health-related nutritional knowledge (high or low-knowledge group). Knowledge related to bone health and calcium, and dietary habits was assessed, and the preference for and intake frequency of calcium-rich food were collected and analyzed using food frequency questionnaires. The high-knowledge group showed a significantly higher rate of nutritional education experience (33.9%) when compared with the low-knowledge group (18.9%). Not only were the perceptions regarding milk and dairy products more positive in the high-knowledge group (P<0.05), but the intake frequency of calcium-rich foods, such as tofu, soybean, and anchovies, was also higher in this group compared to the low-knowledge group (P<0.05). Overall, the preference for all calcium-rich foods was positively correlated to their intake frequency (P<0.05). Nutrition education experience and the recognition of the need for such education were positively correlated with the bone health-related nutrition knowledge score (P<0.05). In conclusion, bone health-related nutritional knowledge can affect calcium-related dietary behavior and increase the intake of calcium-rich food of 20~30-year-old women and this can contribute to the prevention of osteoporosis. To improve bone health-related nutritional knowledge among young women, it may be important to provide nutrition education.

The purpose of this study was to survey the concern for nutrition and the degree of nutritional knowledge of elementary school children's parents and their perception on the eating habits of their children. This study also investigated the effects of the concern for nutrition and the nutritional knowledge on the eating habits of their children. The questionnaire was answered by 383 mothers and fathers in the Kyonggi area. The general nutritional attitude and the perception of their children's eating habits were represented by frequencies and analyzed tv chi-square test, and Fisher's exact test. The difference of nutritional knowledge was represented tv mean and S.D. and was analyzed by one-way ANOVA test. Statistical significance was tested at the 0.05 level. The main results of the study are summarized as follows. 1) Parents had a comparatively deep concern for nutrition and a high level of knowledge. With increasing concern for nutrition, nutritional knowledge tended to be better and the higher proportion of participation in the nutritional education program increased. 2) The majority$(58.5\%)$ of the subjects thought that the eating habit of their children was not appropriate. The subjects had relatively high recognition about their children's eating habits and pointed out the unbalanced diet, snacks, and skipping a meal among their children's eating habits. Nevertheless, there were no significantly differences among the concern for nutrition of the parents and perception on their children's eating habits. As the parents' nutritional attitude, concern for nutrition, and nutritional knowledge can affect the children's eating habits, tire suggest that schools open nutritional education programs for parents in order to acquire proper food and nutrition information, and that schools and homes should be more closely connected.
