The longitudinal changes in transitional milk intakes and body weight of infants(18 boys, 10 girls) have been studied in the part of Kangwon Province from 7 days to 15 days postpartum. Milk intakes at 7, 10, 15 days postpartum were 474$\pm$155, 524$\pm$154 and 547$\pm$130g, respectively. The mean milk intakes were 515g from 7 to 15 days postpartum. Milk intakes of boys were significantly higher than those of girls. The transitional milk intakes per weight of infants appeared 147$\pm$41g/kg. The number of feed per day of boys were significantly higher than those of girls. Milk intakes per fed were 56$\pm$20g. The transitional milk intakes were affected by gestational period(p<0.05), maternal height(p<0.05) and mother's transitional milk yields (p<0.001). Infants transitional milk intakes were 82.6$\pm$17.0% of mothers transitional milk yields. Infants gained its weight 24.6, 40.1 and 39.0g/day at, 7, 10, 15 days postpartum, respectively.

This study was carried out to evaluate high-school students' nutrient intakes according to the status of body mass index, and to analyze the Physical health status. The volunteers were 560 high school students in 8 provinces, but 511 students were analyzed. It was used questionnaire method as an instrument tool. The questions were composed with socio-demographic characteristics, physical health condition by CMI. and the evaluation of food consumption by 24 hours recall method. Anthrophometric measurement of height and weight was used the data of health chart of each school-class. The family situation of the subjects was mostly nuclear family(73%), agricultural work(53%), and normal living situation(75%). The students of the BMI range of 18-23 were 71%. but those of the overweight(over 23) were 15%. The individual characteristics were different in BMI. Female and third grade students were more of BMI scores. The overall nutrient intakes of students were low compared with Korean RDA of adolescent. especially iron. calcium. vitamin A, and riboflavin. The mean adequacy ratio(MAR) of nutrient intakes was 0.45$\pm$0.23 only. The energy nutrients, ash, and vitamin A intakes were significantly different according to the different BMI groups. But the other mineral and vitamin intakes were not different according to BMI. By the correlation of individual characters with BMI, height was negatively and weight and school grade were positively correlated, but sleeping time and study accomplishment were not correlated. By the correlation of nutrient intakes with BMI, there were negative correlation with the intakes of energy, carbohydrates, potassium, and thiamin. According to this results, We concluded that Korean high-school students living in rural were lower intake of nutrients(iron, vitamin A, and riboflavin) and unbalanced nutrient intakes(MAR of 0.45$\pm$0.23). The state of lower intakes of energy nutrients and vitamin A intakes in higher BMI group mean the students spend their effort to reduce BMI for avoiding obesity. But they need to balanced diet. and good nutrient intakes. These situations would be necessary for students to ameliorate quality of living in rural.

In order to identify valuable factors for improving dietary quality of Korean rural elderly, the consumption frequency of food groups, dietary habits and health behaviors related to nutrient intakes of the elderly over 85 of Sunchang County were studied. The 171 subjects (61 males and 110 females) were chosen from Sunchang Province by stratified sampling. Among food groups, the consumption frequency of meat and fish groups influenced significantly on their nutrient intakes than the other groups. The subjects consuming more than 4 times per week of meat or fish had significantly higher nutrient intakes level than the other groups. The group consuming milk and milk products everday was higher in vitamin $B_2$ intake level than the other groups. Among dietary habits, the groups with good appetite and regular mealtime compared with the groups with low appetite and irregular mealtime had significantly higher nutrient intake levels. The family type was the determining factor of nutrient intakes. The subjects living with family members consumed higher nutrient intakes than the subjects living alone. The smoking and the alcohol consumption themselves did not affect nutrient intakes, but the subjects having alcohol consumption frequently more than once a day had lower nutrient intakes than the others. The group with dentures did not differ significantly from the without denture group in nutrient intakes; however, those who had chewing problems showed the lower nutrient intakes compared to those who did not have chewing problems. The subjects with more than two kinds of clinical symptoms had lower nutrient intakes than the subjects with less than two kinds of clinical symptoms. These results indicate that the identifying factors for desirable nutrient intakes of rural elderly were characterized as appropriate consumption frequencies of meat and fish, good appetite, living with family, regular mealtime, chewing without difficulty, and low incidence of chronic disease.

The aim of this study was to assess the nutrient intakes of the elderly subjects in Korea. Dietary assessment was carried out using a semi-quantitative food frequency questionnaire (SQFFQ) developed by our laboratory, which included 98 commonly consumed food items selected from 1998 National Health and Nutritional Survey for Korean population. Subjects (n = 2,660) aged 50yr and over were recruited in Seoul, 6 metropolitan cities, and 8 mid-size cities. Calcium and riboflavin intakes of the elderly subjects aged 65 yr and over (n = 1,974) were much lower compared with Korean RDA. Nutrient intakes of the three age group (50-64 yr, 65-74 yr, 75 yr and over) were decreased as age increased in male and female elderly. Nutrient intakes of male elderly, 75 yr and over, were significantly decreased while in female elderly nutrient intakes were gradually decreased as age increased. Over 30% of the elderly subjects did not meet 75% RDA for calcium, iron, vitamin A, and riboflavin. The proportion of the elderly subjects whose intakes were below 75% RDA was much higher than the elderly whose intakes were above 125% RDA, especially among the elderly aged 75 yr and over. This study revealed that the Korean elderly had inadequate intakes for many nutrients. This will cause a serious nutritional problem for the elderly.

Objectives: The purpose of this study was to investigate factors related to nutrients intakes among young children aged 1-5 years and their mothers. Methods: The study subjects were 621 young children and their mothers from the data of 2nd year (2014) and 3rd year (2015) of the 6th National Health and Nutrition Survey. To find a difference of Recommended Nutrient Intake in young children and their mothers, independent t-test, ANOVA, and Duncan test as a post-hoc analysis were used. For the factors influencing young children Recommended Nutrient Intakes, hierarchical multiple regression analysis was used. Results: The mean score of Recommended Nutrient Intakes was $6.92{\pm}2.17$ in young children and $4.74{\pm}2.06$ in mothers. The Recommended Nutrient Intakes of young children was increased according to gender (boy) (p=0.001), increasing young children age ($p{\leq}0.001$), young children breakfast frequency (p<0.001), mothers age (p<0.001), education level (p=0.020) and mothers lunch frequency (p=0.002) and family income (p=0.007). The Recommended Nutrient Intakes of mothers was increased according to their age (p=0.005), family income (p=0.020) and having breakfast (p=0.038). The factor that influenced young children Recommended Nutrient Intakes was their mothers Recommended Nutrient Intakes (${\beta}=0.21$, p<0.001). Conclusions: Given the results, it is necessary to establish a plan or nutrition education for young children's menu differently depending on their age and gender. Since mothers' Recommended Nutrient Intakes influence their young children's Recommended Nutrient Intakes, it is necessary to provide mothers' with nutrition education about the importance of mothers' nutrition management and right nutrient intakes, and to make customized nutrition education guidelines in consideration of mothers' characteristics.

Poor dietary habits and inadequate nutrient intakes are of concern in the elderly, even it is worse in rural areas. In the present study, we conducted the anthropometric measurement and the dietary intakes including macronutrients, minerals and vitamins to assess the nutrient intakes and nutritional risk in elderly people in rural kyungpook province in South Korea. Subjects (n = 168, mean age, 67.3 yrs) were interviewed using d general questionnaire and 3 days of 24-hours recall for dietary intake. Nutrient intakes were analyzed using CAN-pro soft program and compared to Korean RDA and nutrition reference values (NRV). The anthropometric measurement showed that the weight and the height of the subjects in the rural area were below the average of the same age of Korean elderly people. The energy and protein intakes were 85％ and 90％ of Korean RDA, respectively. The intakes of lipid, cholesterol and dietary fiber were 62％, 40％ and 22％ of NRV for Korean adults. Main sources for protein and lipid intakes came from the vegetable sources and this pattern was more prominent in female elderly people. Ca intake was half of Korean RDA (56％), while P intake was 132％ of Korean RDA. For the antioxidant trace mineral (Fe, Cu, Mn, Zn, and Se) intakes, Fe and Zn intakes were 78％ and > 103％ of Korean RDA. Cu, Mn and Se intakes were > 113％, > 275％, and > 185％ of Korean NRV. Thiamin, niacin and vitamin C intakes were above Korean RDA, but the intakes of vitamin A and riboflavin were 88％ and 63％ of Korean RDA, respectively. On summarizing the results of the present study, the elderly people in rural area consume less lipid, cholesterol, Ca, and dietary fiber. Ca intake is lower, while P intake is higher, and this would be the potential risk for bone health. Also, Na intake was high, which can be the potential risk for the cardiovascular disease prevailance. Vitamin intakes were fairly good status, excepting riboflavin. Antioxidant mineral intakes were much higher than Korean NRV, unexpectedly. The results suggest that the elderly people in rural area have inadequate intakes of protein, lipid, dietary fiber and Ca, which mainly should be supplied from animal products. Recommendations to increase diet variety would be emphasized for this nutritionally poor-conditioned subjects, specially including animal food products and high dietary fiber food.

The assessment of children's nutritional intakes is important because any nutritional inadequacies or toxicities may have adverse consequences. Studies on the nutritional intakes of Korean children are limited. The aims of this study were to determine anthropometric indices, estimate selectee nutrient intakes of young Korean children, and compare these intakes with current Dietary Reference Intakes for Koreans. This study included 136 healthy children(65 boys, 71 girls), 2-6 y old, living in Kwangju, Korea. Weights and heights were measured. Three consecutive 24-h food recalls were obtained. According to International Obesity Taskforce BMI cutoffs, 8% were overweight and 2% were obese. The energy intakes of 40% were < Korean Estimated Energy Requirements, while all subjects consumed $\geq$ Korean Estimated Average Requirement(EAR) for protein. The majority of the children consumed > Korean EAR for iron, zinc, vitamin $B_1$, vitamin $B_2$, vitamin $B_6$, and niacin. Vitamin E intakes of 65% of the Korean children were < Korean Adequate Intake, and approximately half of the subjects had < Korean EAR for calcium and for folate. Many young children in Kwangju, Korea, likely have inadequate status of calcium, folate, and vitamin E.

The study was carried out to assess whether the nutritional management program by dietician at child center can affect nutritional status of children at child care center. The diet intakes were measured by mother\`s record at home and by direct weighing at child care centers, and the hight and weight of children were measured before and after nutritional management program for 3months to see the effects. The energy intakes were significantly increased 56.29 Kcal after program, and protein 3.61g, lipid 3.12 g, calcium 49.71mg, iron 0.39 mg, vitamin B$_1$ 0.084 mg, vitamin B$_2$ 0.116 mg, and vitamin C 10.10 mg, respectively, except vitamin A and niacin. the significant changes of nutrient intakes were more at higher age group compared to at the lower age group, and more at girls compared to boys, Although the significant increase fo nutrient intakes at child care center, most nutrient intakes at home were not significantly changed, except energy, lipid, iron, vitamin A. The changes at changes of fat and calcium intakes for 3 months were positively correlated to the change of Z-score for weight, and the change of A-score for weight was positively correlated to changes of Z-score for height. The results showed that the nutritional management program for 3 month at child care center can increase nutrient intakes significantly and the incresed nutrient intakes can enhance children\`s growth.

This study examined within- and between-person variation in nutrient intakes in order to estimate the degree of precision in dietary assessment among 37 males and 46females whose mean age was 70.4 years old. To collect dietary data, each subject was interviewed 5 or 6 times using a 24-hour recall method during a 3 month period. Within- person variation ranged from 23.5% to 101.2%. Lower values of within-person variation were observed in energy, carbohydrated, protein and phosphorous while higher value was observed in vitamin A. Between person variations of nutrient intakes ranged 12.6-23.5% in most nutrients. With 1 day dietary data, observed nutrient intakes were estimated to within 6-25% of the group's usual9true) intakes and 52-198% of the individuals' usual intakes. The values of these maximum percentage deviations became smaller when the number of dietary recalls increased. The results of this study suggest that the Korean elderly subjects appear to have a slightly less diverse diet compared to young Korean women. Within persons, intakes of nutrients largely from animal sources were more variable for the Korean elderly than for their counterparts in Western countries. This study also implies that commonly used 1 day dietary study may be appropriate for assessing group means of nutrient intakes, but clearly not appropriate for assessing individual's nutrient intakes.

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.
