The aim of this study was to evaluate the food and nutrient intakes in 5th to 8th grade school boys and girls. A total of 1,333 students were recruited from 1 elementary and 1 middle school, both located in Seoul. The data on food and nutrients intake were collected by 3-day food record. The food intake was calculated as the percentage of total energy intake according to 21 food subgroups. The consumption of noodles, and meat's products (including ham and sausage) groups were higher in 7th and 8th grade than 5th and 6th grade. On the other hand consumption of vegetables and milk & its products groups were lower in 7th and 8th grade. As results, calcium, riboflavin, and vitamin C intakes were lower in 7th and 8th grade students. Dietary patterns by cluster analysis resulted in $77\%$ of subjects with traditional pattern based rice and kimchi, and $23\%$ with modified pattern. All students regardless of grades showed high fat intake, above 20 percent energy intake from fat, and high cholesterol intakes. In conclusion, there was significant difference between 5th and 6th grade primary school students and 7th and 8th junior school students regarding food and nutrient intakes; It should be necessary to provide proper nutrient education and monitoring in order to establish good dietary profile.

To assess the food intake and diet quality of preschool children in Pusan, dietary survey was conducted with 176 subjects using 24hr recall method. Diet quality was assessed by food group pattern, dietary diversity score(DDS), dietary variety score(DVS), and dietary frequency score(DFS). The total number of food items consumed was 307. The foods consumed most frequently were rice, Korean cabbage kimchi, milk and green onion. When investigating the consumption pattern of major six food groups, 38.1% of subjects consumed all six groups. Food group was missed in order of fruit(41.5%), sweet(19.9%), dairy(16.5), vegetable(4.5%) and meat(1.7%). The mean values of DDS, DVS, and DFS were 5.16, 13.82, and 16.07 re spectively. Persons who had higher DDSs also had higher DVSs(p<0.001). DDS, DVS and DFS correlated positively with NAR(nutrient adequacy ratio) and MAR(mean adequacy ratio) significantly. Associations between the NAR of most nutrients and MAR with DVS and DFS were higher than those between the NAR of most nutrients and MAR with DDS. People with DDS of above 6 or DVS of above 16 or DFS of above 21 met two thirds of recommended dietary allowance for nutrients. Based on the result of the food group intake, the food intake of subjects was not adequate, especially the fruit and dairy groups. When assessing the dietary quality of subjects using DDS, DVS and DFS, many people appeared not to have a desirable food intake.

The purpose of this study was to examine household food insecurity and the associations of food insecurity with socioeconomic characteristics, food behaviors, health status and nutrient intake among elderly people in a rural area. This study included 191 elderly people (mean age = $72.0{\pm}7.4$) in Jeollabuk-do, Jangsu-gun. House food insecurity was measured using an adapted version of the USDA short form household food insecurity scale, and nutrient intake measured by a 24-hour dietary recall. Only 15.2% of the subjects were in food-insecure households, 84.8% of the elderly households were food-secure. The food-insecure households were significantly lower in the number of family, frequency of shopping, and perceived health status than the food-secure households. In addition, they had serious tooth problems and NSI (Nutrition Screening Index) scores. Food-insecure households were significantly lower in most areas of nutrient intake (energy, protein, fat, Ca, P, Fe, K, Na, Zn, Vit. $B_2$, niacin, Vit. E), and also lower in nutrient intake compared to dietary reference intake (energy, protein, P, Fe, K, Na, Vit. $B_1$, Vit. $B_2$, niacin, Vit. E). These results suggest that the household food insecurity measures used in this study were an important indicator of nutritional well-being among elderly persons in the rural area. Food insecurity should be considered an important issue to public health and food service programs should be expanded for food-insecure households in rural areas.

Especially, the teenage period, an important lifetime to develop both physically and mentally, needs to be helpful to promote the growth of the body and to keep a well-balanced mind through a balanced and nourishing diet. It is well known that the western style fast food is the most liked meal by teenagers. Wrong recognition about fast food and its frequent intake by adolescents can lead to unbalanced diet and food behaviors which may also connect with a poor impact on their personalities as well as their physical health. In this study, therefore, relationships between fast food intake frequency and food behavior, sociability, and personality, such as anger expression, were surveyed from 1,295 adolescents (666 in Seoul, 316 in Changwon, and 313 in rural communities), and then analyzed using SPSS program. The results are shown as follows. The fast food preference score and the fast food intake frequency score showed no differences between male students (22.9/30, 14.4/30 respectively) and female students (23.0/30, 14.0/30 respectively). But, the fast food preference score correlated positively with the intake frequency score (r=0.304) significantly (p<0.001). The more frequently eating of fast food group showed significantly lower scores (r=-0.233, p<0.001) in food behaviors. The frequency of fast food intake had no relationships with sociability, but it had a significantly effect on anger expression (r=0.213, p<0.001) and control (r=-0.l47, p<0.001). From these results, we could see the necessity of various nutrition education programs to build proper eating-out habits and also more studies are needed to find the relationships between fast food intake and growth and personality.

To assess riboflavin status by dietary intake and urinary excretion of preschool children in Busan and to evaluate the relationship of intakes of food and nutrient with urinary riboflavin excretion, riboflavin food frequencies of 40 common foods affecting intakes of riboflavin by food fequency method, nutrient intake by 24hr recall and 24hr urinary riboflavin excretion were measured with 97 preschool children. The mean riboflavin intake was 0.90 mg and above RDA. Dairy group was the primary source of riboflavin intake and provided 44.8% of the total daily riboflavin intake. The mean urinary riboflavin excretion and riboflavin excretion per gram of creatinine were 395.21$\mu\textrm{g}$ and 2110.41$\mu\textrm{g}$ respectively, The mean riboflavin intake (p<0.01, p<0.01), riboflavin density (p <0.001, p<0.001) and urinary riboflavin excretion per gram of creatinine (p<0.05, p<0.05) were significantly low with the two patterns of food group intake where dairy group was omitted (GMVFDS = 111101, consuming no dairy group and GMVFDS=l11001, consuming no fruit and dairy groups). On the basis of urinary riboflavin excretion per gram of creatinine, 14.3% of subjects in the group aged 1 to 3 and 18.2% of subjects in the group aged 4 to 6 were at risk of deficiency respectively. The urinary riboflavin excretion per gram of creatinine showed positive significant correlations with usual intakes of riboflavin from food groups of dairy (p<0.05), meat (p<0.05) and animal (p<0.05). So nutritional education is needed in order to consume dairy food group daily and to increase usual intake of animal food group including meat.(Korean J Nutrition 35(9) : 970~981, 2002)

Contributions of specific foods to absolute intake and between-person variance in 13 nutrients were examined to develop a short food frequency questionnaire (FFQ) for the Korean elderly using dietary data collected by a semiquantitative FFQ with 96 food items. The contributions of specific foods to 90% absolute nutrient intake were measured by assessing their percentage to the total consumption of a nutrient by our samples(n=98). To assess the contribution of the foods to the between-person variance in intake of each specific nutrient, stepwise multiple regression was performed. Cumulative R2 served as the measure of contribution to variation in intake. The most important food source of absolute intake was rice for energy and protein. Important foods of between person variance contribution include bread for energy and pork for protein. Important foods of absolute and variance contribution of nutrient intake were similar for fat(noodles including jajangmyun and kalguksu), calcium(anchovy and milk) and vitamin A (carrot). The number of foods necessary to account for the variation in nutrient intake among older people in Korea differ considerably by nutrient: 18 - 43 and 8-26 foods were accounted for the respective 90 and 80% of absolute intake depending on nutrients. Carbohydrates and vitamin A and C had relatively a few major sources, thus may be assessed well by a small number of foods. Conversely, iron, potassium and B vitamins appear to need longer lists of foods. Fewer numbeer (6 - 12 and 4 - 9) of foods were required for the corresponding percentages of between-person variation for all nutrients. Depending on nutrients, 0.980-0.995 and 0.924-0.987 were respective correlation coefficients of nutrient intakes measured by 96 food items with those by lists of foods for 90% and 80% of absolute intake contribution. These findings suggest that an incomplete food list on the basis of its contribution to absolute and between person variation intakes may still be effective in discriminating among individuals. The results of this study may be useful in the design and use of dietary questionnaire.

The purpose of this nutritional survey on the actual conditions of group feeding is to be of value for promoting the health of the blue collar workers through consice understanding of food intake trends in businesses as well as realizing our desirable target. The results of the survey are summarized as follow. 1, Status of food economics 1) The average feeding cost amounts to 453 won per day per person. 2) The average school years of food buyers were 12.3 years, cookers were 12.0 years and dieticians were 14.5 years. 3) Kerosene(57.6%), gas(24.2%), electric(12. 1%) and cool briguette(6.1%) were used for fuel. 2. Status of food intake The average food intake per person per day in surveyed businesses was 1193.4g. The total intake of food was consisted of 42% grains, 40.4% vegetables, 4.7% legumes, 4.5% fish and shellfish, 4.0% potatoes, 1.6% meats, 1.0% seasonings. 0.8% eggs, 0.5% sea weeds, 0.3% oil and fats, 0.1% sugar. These findings led us to the conclusion that workers in the surveyed businesses retied heavily on plant foods. 3. Status of nutrient intakes 1) The average intake of calorie was 2752.6 kcal per day, which was slightly higher than 2,700 kcal of RDA. Though the quantity was above the level of RDA, it was largely from plant foods. 2) The average intake of protein was 84.7g per day, which was slightly higher than 80g of RDA. 3) The average intake of fat was 26g per day, which was much lower than 36g of RDA. 4) The averse intake of calcium was 532.3mg per day, which was lower than 600mg of RDA. 5) The average iron intake was 9.8mg per day, which was much lower than 10mg of RDA and 18mg of HDA for women. 6) Intakes of vitamin group were high. Especially, intake of vitamin A was 2-3 times higher than RDA and intake of vitamin C and niacin were 2 times higher than RDA.

The purpose of this study was to identify dietary factors related to the incidence of diabetes mellitus in Korea. The study consisted of 165 diabetic patients, male and female, aged 30 to 70 years and 198 healthy persons as controls. Diabetic patients who had been diagnosed with diabetes mellitus for less than five years before the study period were recruited from eight different hospitals located in Seoul, Korea. Socioeconomic status, state of illness, physical activity, food habits and food intake were assessed. Food intake was assessed by food frequency questionnaire method using a 105-food frequency questionnaire developed for diabetic patients. The stress and activity indices of diabetic patients were not significantly different from control, but alcohol consumption and smoking levels were higher in diabetics than controls. Other diseases of male diabetic patients included liver diseases, digestive system diseases, and hypertension, while those of female diabetics were hypertension, neuralgia, arthritis and digestive system diseases. These disease patterns are different from Western countries whose most common complications are hypertension and hyperlipidemia. More irregular and less varied meals were found in the diabetic group compared to the control group, suggesting that diabetic patients have generally undesirable food habits. Otherwise, food and nutrient intake of diabetics did not differ greatly from the control group. It was found that diabetic patients consumed more cereals and less fruit than the control group, and also that male diabetics consumed more alcohol. The carbohydrate : protein : fat energy distribution ratio was 61.7 : 15.8 : 22.5 in male patients and 65.1 : 14.9 : 19.7 in female patients. Discriminant analysis showed that diabetes risk factors differed with sex. In male patients, the important factors were body mass index(BMI), vitamin C intake, family diabetic history and vegetable intake, while in female patients they were BMI, cereals intake, carbohydrate intake, vitamin C intake, stress, food habits and Ca intake. These results show that excessive intake of energy and fat are not the major causal factors in Korean NIDDM. Therefore, the diabetes risk factors of Western countries may not directly apply to Koreans. Mors study is needed to clarify the risk factors of Korean NIDDM.

This study aimed to elicit the variability of appetite and food intake patterns in female college students during different menstrual phases. The craving for certain foods and physiological and psychological symptoms of menstrual phase (pre- and post-menstrual) were investigated by self-administered questionnaire. Three hundred and sixty six students who were 20.9 years old and had $19.8kg/m^2$ of BMI volunteered to participate in this study. Most of the subjects (89.5%) experienced the premenstrual syndrome (PMS) such as irritation, bodily fatigue, nervosity. Symptoms such as tiredness, stomachache, changes in taste and increased appetite were pointed out to be experienced at the onset of the menstrual cycle. The variability of food intake in premenstrual phase, 11.0% of subjects had decreased food intake where as 68.8% had experienced increased intake. The postmenstrual phase, 20.1% had decreased food intake while 45.2% had experienced increased intake due to changes in the appetite. Before starting menstruation, most of the subjects craved for sweets. The group who had experienced abnormal appetite during menstrual phase was significantly high ratio in overweight and obese students (p<0.05). We also observed an association between the PMS score and the variability of eating patterns during the menstrual phase. The students who experienced changing appetite and food intake had significantly high PMS score in the premenstrual phase (p<0.01) and postmenstrual phase (p<0.05). These results suggested a need for future study related to changes in the actual nutrient intake and activity level during the menstrual phase.
