The purpose of this study was to get a data which can provide a basis for future direction in nutritional education and to build up right eating habit and to find the way how to improve food life and the nutritional supply by evaluating the current nutritional intake of average middle school girls through the survey study of their daily food intakes and physical status. The survey of nutritional intakes and physical status in two girls middle schools, namely Jang'hung girls middle school at Jang'hung Up and Bo'song girls middle school at Bo'song Up, were carried by teachers majoring in Home Economics and nurse-teachers from 5 July to 7 July 1983. From a total of 1080 subjects of two girls middle schools, 887 subjects were surveyed. The results obtained from survey are summarized as follow: 1) Physical Status Average height, weight and chest girth of subjects in both middle schools were much lower than the Korean average standard (p<0.005${\sim}$p<0.001) and t-score of differences between two middle school girls were not significant. Rohrer index, nutrition rate and physique rate were also lower than Korean averag standard through all the ages in both girls middle schools. Menarche appeared mainly between the age of 13 to 15 (91.55 %), with a mean age of 14 (35. 01 %) and which was experienced by the subjects of 51.52 percentage among total surveyed Iniddlf school girls. 2) Nutritional Intakes The average daily intakes of all nutrient except iron, vitamin A, thiamin, ascorbic acid and niacin was lower than Korean Recommanded Dietary Allowances (RDA) . Especially average intake of calorie and calcium were much lower than Korean RDA(p<0.001) while average intake of thiamine and ascorbic acid were much higher than Korean RDA (p<0.001). T-score of differences of iron, thiamin, riboflavin between two middle school girls were very significant (p<0.001). Generally iron and riboflavin were the highest rate of intakes through three meals and breakfast took charge of considerable amount of all nutrient intake without omitting anything (about 30 % of daily nutrient intake). The nutrients of which ratio of nutrient intake by snack was more than 16.7 % were vitamin A, thiamin, riboflavin, ascorbic acid etc. and snack foods which were intake frequently in both middle school girls commonly were fruits, milk and milk products, bread and biscuits in sequence. 3) Correlations and t-score between physical status, menarche and nutrient intakes. Average intake of calorie at Jang'hung area was positively correlated with height, weight, nutrition rate and physique rate and this correlation was very significant (p<0.005). Average intake of calorie was also correlated with chest girth and Rohrer index (P<0.05). At Bo'song area, averse intake of riboflavin was negatively correlated with all the items of physical status (p<0.05-p<0.005), vitamin A was negatively correlated with chest girth and Rohrer index (p<0.05 respectively) and thiamin was also negatively correlated with chest girth, Rohrer index and nutrition rate (p<0.05 respectively). Especially niacin showed a negative cor-relation with all the items of physical status very significantly (p<0.005).The time of menarche showed a positive correlation with iron in both middle school girls commonly P<0.05 at Jang'hung, p<0.10 at Bo'song).

We evaluated the nutritional status of 116 Songmyun middle school students. The means of height and weight were similar to the standards published by the Ministry of Education(1991). The height of 79% of the subjects was in the normal range, and the height for 11% was below the normal range. While 27% of the subjects were underweight, 18% and 8% were overweight and obese, respectively. The percentage of anemia was 29%, and the mean urinary urea nitrogen to creatinine ratio was 8$\pm$4. Total daily energy and nutrient intake was 48-103% of RDAs, and especially calcium and iron intake was very low. Carbohydrate, protein and fat intake was 71%, 12% and 17% of total calories, respectively. Breakfast, lunch, dinner and the between meals provided 20%, 37%, 26% and 18% of total energy intake. Energy and nutrient intake from lunch box was 52-95% of the 1/3 RDAs. Our data suggest that the nutrition education for the meal planners of the subjects is necessary to improve the nutritional status of the subjects. In addition, the school lunch program is recommended.

To investigate the nutritional contents of lunchbox of students of elementary school located in Sokcho city Kangwon province, the survey was conducted from April 23 to April 26, 1991. Main dishes and side dishes in lunchbox were weighed and nutrients were analyzed from food composition table. Total daily energy and nutrients intake were reach to RDA's, except for intake of calcium, iron, vitamin A, vitamin Be and vitamin C. Children's height was positively correlated with energy and protein Intake. Fat intake was positively correlated with monthly income and intake of vitamin A was positively correlated, with number of family, This survey suggests that it need nutritional education program and school feeding to improvement of nutritional status for children.

This study assessed yearly trends of food and nutrient intake among high school students aged 16 to 18 years (n=2,377) using the 2007~2015 Korea National Health and Nutrition Examination Survey (KNHANES). Yearly trends of food or nutrient intake were analyzed via logistic regression analysis. The results showed that consumption of sugars & sweets, and beverages & alcohols was increased rapidly during this period (p<0.0001). Intake of meat & meat products, and fish & shellfish also was increased (p=0.0008). Intake of grains and grain products was increased until year 2011 but declined after 2012 (p=0.0025). Consumption of vegetables, and milk & milk products was decreased (p=0.0395). Intake of protein, fat, thiamin, riboflavin, niacin, and iron was increased (p=0.0445). Carbohydrate energy ratio was decreased, whereas fat energy ratio was increased (p=0.0235). Most nutrient intakes satisfied the dietary reference intakes for Koreans except dietary fiber (19.6~26.2%), calcium (46.9~55.2%) and sodium (more than 221.4%) during this period. There was a significant positive correlation between most food group intakes and most nutrient intakes (p=0.0468). Therefore, it is crucial to increase dietary fiber and calcium intake and decrease consumption of sugars, fats and sodium through diverse eating of food groups to ensure balanced nutrition of subjects.

Few studies investigated the effects of nutrition education and exercises in women with osteopenia. This study examined the relationship between changes in dietary intakes and changes in indicators related to bone health in postmenopausal women with osteopenia (-2.5 ${\leq}$ T-score ${\leq}$ 1) after a 12-week intervention. Thirty-one postmenopausal women aged > 50 years residing in Seoul were recruited and participated in nutritional education regarding bone health and general nutrition practices and aerobic exercises (three times a week; 60 min per session). Twenty-five subjects completed the study and were eligible for the analysis. Bone mineral density (BMD) at femoral neck was measured by dual energy x-ray absorptiometry. Serum calcium, osteocalcin, and intact parathyroid hormone (PTH) were also measured. Dietary intake was estimated by using a one-day 24 recall by a clinical dietitian. After 12 weeks, meat consumption increased (P = 0.028) but vegetable intake decreased (P = 0.005). Intakes of animal protein (P = 0.024), vitamin B1 (P = 0.012) and vitamin $B_2$ (P = 0.047) increased, and sodium intake decreased (P = 0.033). Intact PTH (P = 0.002) decreased and osteocalcin (P = 0.000) increased, however, BMD decreased (P = 0.000). Changes in mushroom consumption were positively correlated with femoral neck BMD (r = 0.673, P = 0.003). Changes in animal iron intake were negatively correlated with intact PTH (r = -0.488, P = 0.013) but were positively correlated with osteocalcin (r = 0.541, P = 0.005). These results suggested that the association between animal iron intake and biochemical markers of bone turnover may play an important role in bone metabolism. Further studies are needed to shed light on complicated mechanisms of diet, hormonal levels of bone metabolism, and bone density.

The purpose of this study was to examine the correlation between nutrient intakes and bone mineral density in female university students. A total 27 female university students were measured the anthropometric characteristics, dietary intake and the bone mineral density of carpus using DEXA. The average age, height, weight, % body fat, WHR, and BMI of the subjects were 22.7 years, 161.5 cm, 57.0 kg, 29.9%, 0.8, 21.8 kg/$m^2$, respectively. Bone mineral density of ultradis and distal carpus as T-value were -1.5 and -0.4, respectively. The daily energy intake of the subjects was 1589.0kcal. And the intakes of energy, calcium, iron, zinc, vitamin $B_2$, and folic acid did not meet the Korean RDAs. The daily total food intake of the subjects was 1011.0g and food intake from cereals and vegetables was high. The major food groups of mineral intake were vegetables/cereals/milks/fishes for calcium, cereals/meat/vegetables/fishes for phosphorus, cereals/vegetables/meats for iron, seasonings/vegetables/cereals for sodium, vegetables/cereals/seasonings for potassium, and cereals/meats for zinc. The body weight and body mass index were significantly positive correlated to the bone mineral density of average carpus, respectively. The intakes of animal calcium and vitamin $B_2$ were significantly negative correlated to the bone mineral density of average carpus, respectively. In conclusion, bone mineral density in carpus and nutrient intakes of some female university students were low. Therefore, health management and the study on relation between bone mineral density in various site and long-term intakes of nutrients in many subjects are required.

This study was carried out to investigate the dietary behaviors and nutrient intake of high school girls in Iksan and Seoul cities. The subjects consisted of 122 students in Iksan city, and 136 students in Seoul city. The proportion of subjects who eat meals irregularly was higher in Iksan ($94.8\%$) than in Seoul ($80.9\%$). The proportion of subjects who skip meals was also higher in Iksan ($61.5\%$) than in Seoul ($56.6\%$), and most of them ($69.7\%$) skipped breakfast, even thought they thought that it was the most important meal ($86.4\%$). The subjects tended to overeat at lunch ($41.9\%$) and dinner ($55.4\%$). The main reasons that the subjects skipped a meal were a lack of time (50.7%) and poor appetites ($23.7\%$). Most of the subjects ($57.4\%$) had tried to control their body weight by taking drugs ($40.5\%$), doing exercise ($34.5\%$), and controlling their diet ($25\%$). The average intake of nutrients and energy was significantly higher (P<0.05, p<0.01) in Iksan than in Seoul. The intake was below the RDA recommendations except for phosphorus in I ksan, but was above it except for calcium, iron, and vitamin B2, in Seoul. The indexes of nutritional quality (INQ) of calcium (0.5), iron (0.6), vitamin A (0.8), vitamin B2 (0.7), niacin (0.9), and vitamin C (0.9) were under 1.0 but those of protein (1.0), phosphorus (1.2) and thiamin (1.0) were over 1.0. The INQ of the other nutrients, except protein and vitamin C, was significantly higher in Seoul than in Iksan.

The aim of this study was to assess the nutrient intakes from infant formula and supplemental foods of 246 healthy infants fed infant formula, aged from 5 to 18 months. Subjects were devided into two groups depending on supplemental food type for weaning, Domestic supplemental foods (mainly home-made, n = 129) and Delivery supplemental foods (mainly commercially-delivered, n = 117). Four subgroups were assigned to 5-6 months, 7-8 months, 9-11 months, and 12-18 months by ages, respectively. Dietary assessment was carried out using 24-hour-recall method. Formula intakes in the delivery group tended to decrease accordingly with the ages. However, in the domestic group, formula intakes up to 8 months were similar and decreased after 9 month. Energy, protein, calcium and iron intakes from infant formula and supplemental foods were assessed. Energy intake at 12-18 months were lower than the RDA in both groups. Daily intake of protein and calcium at all ages were much higher than the RDA in both groups. Therefore, protein and calcium overnutrition were elucidated. Especially, protein intake at 5-6 months, calcium intake at all ages from infant formula was higher than the RDA in both groups. Iron intake at 5-6 months from infant formula were higher than the RDA. Consequently, as for infant formula, it was suggested that not only formula intakes but also nutrient content in formula should be reconsidered. On the other hand, nutrient intakes from supplemental foods in the domestic group tended to be higher than that of the delivery group. Especially at 9-11 months, significant differences between the two groups were observed. This may be due to high dependency on commercial powdered baby food in the domestic group. This study revealed that daily nutrient intakes of formula-fed infants are desirable but nutrient intakes from infant formula are too high. Conclusively, this study suggests that as the age of infants increases, formula intakes should be controlled and various supplemental foods besides commercially powdered baby food should be appropriately provided.
