BACKGROUND/OBJECTIVES: The intake of sugar has increased worldwide, and it is well established that childhood experiences and food preferences affect lifelong eating habits. To discourage sugar intake, nutrition education was imparted, and the effectiveness of the nutrition education program was investigated by considering the nutrient density and major dietary sources of sugar intake. SUBJECTS/METHODS: Twenty four-hour dietary recall and sugar intake frequency of 96 pre-school children (educated n = 47; non-educated n = 49) were collected on 3 consecutive days (1 weekend day, 2 weekdays) after 11 weeks of imparting nutrition education. Dietary intake of nutrients and total sugar were analyzed, and the intake frequency of sugar source foods were identified. All nutrition education programs were focused on a hands-on education program, and consisted of cooking lab, play, activity, animation, and visual materials. The difference between the two groups was verified by the Chi-square test or t-test. All statistical analysis was performed with significance level at P < 0.05. RESULTS: Compared to the non-educated group, the intakes of protein (P < 0.001), fiber (P < 0.01), potassium (P < 0.05), iron (P < 0.05), zinc (P < 0.05), and iodine (P < 0.001) were significantly higher, and the intakes of carbohydrate (P < 0.01) and total sugar (P < 0.05) were significantly lower in the educated group. The cumulative percent of sugar intake of top 20 sugar source foods in the educated group (82.80%) was lower than that of the non-educated group (85.75%). The contribution of beverages on total sugar intake was lower in the educated group. The average frequency of consuming sugary foods was significantly lower in the educated group (P < 0.05). CONCLUSIONS: Our results indicate that nutrition education on discouraging sugar intake is effective in reducing the amount of total sugar consumed, resulting higher nutrient density in the diets of pre-school children.

The purpose of this study was to investigate differences of food preference and nutrient intake of students between elementary school and middle school in the same area and to provide data for better school food service. The subjects were 486 students, third to sixth grade of 3 elementary schools and first to second grade of 1 middle school in Nam jeju gun, Jeju, and the survey was conducted during June 1999. Food preference was assessed using questionnaires and 24-hour food intake was assessed using dietary record method. Data of weight and height were obtained from annual physical examination conducted at schools in May 1999. All the variables were compared among 3 groups in each gender: third and fourth grade elementary school(ES3,4), fifth and sixth grade elementary school(ES5,6), and first and second grade middle school(MS1,2). The results were summarized as follows. The average height, weight and BMI for the 3th grade boys in elementary schools met the national averages, but those of the others are below the national averages. Although general pattern of food preference looked similar among groups, food preference scores were significantly different among groups in 38 kinds foods for boys, and 27 kinds of foods for girls. MS1,2 group showed significantly lower food preference scores for most of foods as compared to those of ES3,4 and ES5,6 in both genders. Students of higher grade took more starch foods such as instant noodle, stewed rice cake and snacks. Average energy intakes of all the groups except MS1,2 girls were lower than recommended dietary allowances(RDA), and average intakes of protein, vitamins B1 and C met RDA, but the other nutrients were taken less than RDA and especially the intakes of iron, calcium and vitamins B2 were poor. Most of nutrients taken by school food service meal provided a major proportion of intakes. In conclusion, students of middle school were more particular about their foods served at school food service and marked lower food preference score than elementary school children and more conscious about their weight and appearance. These points should be reflected in planning food service menu at middle school.

In this study, we evaluated the dietary fatty-acid pattern and serum fatty-acid composition of middle school students (total, 355 ; male, 182 ; female, 173), who are vulnerable to excessive and unbalanced food intakes such as fatty acids and energy. In serum lipid levels, total Chol (p<0.05) and HDL-Chol (p<0.001) levels of female students were significantly higher than those of mal, students. The average fat intake was 23-26 energy % which falls in with the current recommendation level (15-25%) for adults. Although the average P/M/S ratio of dietary fat was 1.1/1.2/1.0 which approaches the recommended ratio, the average range of $\omega$6/$\omega$3 fatty acid ratio of dietary fat was found to be 12.0-16.5, which is higher than the presently recommended range of 4 -10. Some of the very high values found in this study were partly explained by the fact that the range of individual variation of $\omega$6/$\omega$3 ratios was very large. Mean daily intake of Chol was 357-361 mg. The n3 fatty acid intake of middle school students was higher in the LFHM (high fish low meat) group than in the LFHM (low fish high meat) group. EPA and DHA intakes appeared to be significantly higher (p<0.01) in the HFLM group than in the LFHM group as expected. Dietary total $\omega$3 fatty acids (p<0.05) and EPA (p<0.01) were also negatively associated with serum AA($\omega$6) levels. Interestingly, energy intakes and dietary SEAs such as 12 : 0 (p<0.05), 14 : 0 (p<0.01) and 16 : 0 (p<0.05) were negatively associated with serum AA ($\omega$6) levels. To lower the $\omega$6/$\omega$3 ratio of dietary fatty acids for children, frequent consumption of $\omega$3 series fatty-acid rich foods such as soy bean, bean products and fish is recommended. Detailed guidelines should be developed in recommending balanced food intake and qualitative fat intake for Korean adolescents taking heterogeneous groups into consideration. In accurately evaluating fatty acid intake, it is also necessary to have the fatty acid composition data of all foods consumed in each country.

Prevalence of obesity and dietary consumption of ten-year-old school children in Seoul were investigated. Three hundred forty boys and three hundred forty two girls from families of various housing pattern in Seoul were chosen for this study. Informations of the stduy were obtained from April 22 to June 11, 1985, by means of prepared questinnaires for general environmental factors, anthropometry for height, weigth and triceps skinfold theickness and interview to get 24 -hour food intakes of individuals. All the data collected were analyzed by using SPSS program. Average nutrients intakes of the subjects were satisfactory with respect toquality or quantity . Children from A group tended to consume more nutrients than B or C group. Physical growth of the subjects were similar to the ones for average school children in Seoul, but greater than korean national average. Children from A group were taller and heavier than B group whom were taller and heavier than C group . Prevalence of obesity were 15.7 % and 11.7 % of the subjects according to standards of relative body weight and triceps skinfold thickness. Higher prevalence were observed in boys than in girls and children from A group than B, and B group than C group. so therefore it could be summarized that children from A group consumed more nutrients, had better physical growth, and became obese more frequently than children from B or C.

Korea's aging population has been remarkably increased. They want to have not only extension of life expectancy but also improving quality of life. To maintain the quality of life, it is essential to have good nutrition. However, nutritional status of elderly in Korea has problems qualitatively and quantitatively. Risk factors for poor nutrition are advanced age, woman, living alone and low economic status. Another risk factor in rural area is season because seasonal changes can affect food intake of elderly. Thus this study surveyed the health status and dietary intakes of elderly by season in rural area. In this study, the elderly were grouped as group 1 {elderly who have one risk factor for chronic diseases (obesity, hypertension, dyslipidemia, diabetes)} and group 2 (elderly who have more than 2 risk factors). Can-Pro 3.0 was used for dietary data analysis and SPSS 12.0 program was used for statistical analysis. Obesity had the highest percentage 62%, followed by hypertension 59.5%, dyslipidemia 21.5% and diabetes 11.6%. Obesity, hypertension, and dyslipidemia were high in winter and WHR, diabetes and anemia were high in summer. Mean intakes of energy and nutrients were less than RI. Nutrients which were changed most by season were vitamin A and Vitamin C. Intakes of calcium and folic acid were less than recommended in summer. The ratio of CPF for carbohydrate was higher and fat was lower than recommended. In conclusion, the nutrient intake of Group 2 was better in quality but Group 1 was better in quantity. Nutrient intakes were poor in summer. In rural area, more careful nutritional assesment and management are needed for aged population, especially in summer.

Inadequate nutritional status of pregnancy can cause underweight and premature birth, undergrowth and deliverance of physically and mentally defected babyies. The purpose of this study is to provide guidelines for preventing preterm delivery in the aspect of nutritional factors. The nutrient intakes were compared between a preterm delivery group and a normal term delivery group to recognize risk factors of preterm delivery. The results obtained are summarized as follows. The pregnancy period was statistically longer in the normal term group (p<0.0001). Weight increase was statistically higher in the normal term group (p<0.0001). Calories (p<0.05), carbohydrates (p<0.0005), dietary fibers (p<0.0001), potassium (p<0.0005), vitamin $B_1$ (p<0.0005), vitamin $B_6$ (p<0.05), vitamin C (p<0.0001), and folic acid (p<0.05) intakes were statistically higher in the normal term group. Nutrient density of vitamin $B_1$ (p<0.05) and vitamin C (p<0.0001) in the normal term group was statistically higher. Nutrient adequacy ratio of zinc (p<0.05), vitamin $B_1$ (p<0.05) and folic acid (p<0.05) were statistically higher in the normal term group. Index of Nutritional Quality of vitamin $B_1$ (p<0.05) and vitamin C (p<0.0001) were statistically higher in the normal term group. In this study, the normal term delivery showed higher intakes of calories, carbohydrates, dietary fiber, crude fiber, potassium, vitamin $B_1$, vitamin $B_6$ vitamin C and folic acid than the preterm delivery group. Deficiencies in various nutrients may lead to preterm delivery, therefore, balanced nutrient intake is recommended to prevent preterm delivery.

The purpose of this study was to investigate the effects of preschool children's taste preferences on their intake of nutrients and the degree of dental caries. The subjects were 126 preschool children (boys 62 and girls 64) in Daegu area. Their taste preferences and food intake were investigated and their teeth were also examined. The energy intake of boys (1550 kcal) were significantly higher than that of girls (1441 kcal). Daily dietary intakes of nutrients-except niacin and vitamin C-were higher than those of RDA. Vitamin B$_1$ intake of the group preferring a salty taste was significantly lower than that of the other group (p<0.05). Vitamin B$_2$ intake of the group preferring a salty taste was significantly higher than that of the other group (p<0.05). Vitamin C intake of the group preferring a hot taste was significantly higher than that of the other group (p<0.05). The group with a preference for sweet had more experiences of dental caries and more decayed teeth than the other group, but which is not significant. The experiences of dental caries were negatively correlated with protein intake (p<0.01). The decayed teeth were negatively correlated with energy and protein intakes (p<0.01). Our data suggested that taste preferences are associated with vitamins intake and the degree of dental caries in preschool children. It means the sweet preference increased the experiences of the dental caries.
