BACKGROUND/OBJECTIVES: The prevalence of atopic dermatitis in infants is increasing worldwide. However, the nutrient intake status of infants with atopic dermatitis has not been studied properly. This study was conducted to compare the nutrient intake status of infants in the weaning period with atopic dermatitis by feeding type. MATERIALS/METHODS: Feeding types, nutrient intake status and growth status of 98 infants with atopic dermatitis from age 6 to 12 months were investigated. Feeding types were surveyed using questionnaires, and daily intakes were recorded by mothers using the 24-hour recall method. Growth and iron status were also measured. RESULTS: The result showed that breastfed infants consumed less energy and 13 nutrients compared to formula-fed or mixed-fed infants (P < 0.001). The breastfed group showed a significantly lower intake rate to the Dietary Reference Intakes for Koreans than the other two groups (P < 0.001). In addition, they consumed less than 75% of the recommended intakes in all nutrients, except for protein and vitamin A, and in particular, iron intake was very low, showing just 18.7% of the recommended intake. There was no significant difference in growth by feeding type, but breastfed infants showed a significantly higher rate of iron deficiency anemia (P < 0.001). CONCLUSIONS: Continuous management programs should be prepared for breastfed infants with atopic dermatitis, who are in a period when rapid growth takes place and proper nutrient intake is essential.

In this study, the Korea National Health and Nutrition Examination Survey in 2016 examined the nutrient and food intake of women in their 20s and 30s according to the number of meals a day, and the results were as follows: The study included 256 women in their 20s and 474 women in their 30s. Women in their 20s and 30s ate two meals a day, indicating that the notion of three meals a day was gradually changing to two to three meals a day. Those in their 20s and 30s who eat one, two or three meals a day were consuming less than the estimated energy requirement of the DRI for Koreans 2015. The vitamin A and C were eating less than the recommended intake in all meals. In the case of minerals, calcium was taken less than the recommended intake in all meals, but sodium was taken above the goal intake in all groups. Women in their 20s and 30s must reduce their intake of saturated fatty acids and sodium, and increase their intake of vitamins A, C, calcium, and potassium. Women in their 20s and 30s drank a lot of coffee, ate baechu-kimchi and rice frequently per week.

Literature suggests that iron deficiency anemia is prevalent among pregnant women all over the world. This study was designed to evaluate the iron status of pregnant women during the fist five months, with the intention of determining ways to reduce the prevalence of iron deficiency anemia among pregnant women in Korea. We collected dietary information and measured the biochemical status of iron in 171 pregnant women over 16 weeks of gestation (=16.7$\pm$2.34 week). Dietary intakes for 3 days were collected using the 24 hour recall and food record methods. The daily Fe intake was measured using the food frequency method. The Body Mass Index (BMI), calculated by using the pre-pregnancy weight and height, indicated that 31.3% of subjects were under-weight. We divided the subjects into normal and anemic group by using the serum ferritin levels. It appeared that the mean dietary intake of iron was 52.3% of the recommended level for pregnant women. The dietary quality evaluation showed that pregnant women ate only 58% of the recommended amount in the food groups of meat, fish, eggs, beans and milk and dairy products. The hematological indices showed that the mean Hemoglobin (Hb) was 11.9 g/dl, Hematocrit (Hct) was 35.1%, ferritin was 23.9 $ng/ml$, and transferrin was 297.3 ${\mu}g/dl$. The dietary intake of iron was significantly lower and the vitamin C intake was significantly higher in the anemic group. The pre-pregnancy BMI was significantly lower in the anemic group. Variables affecting iron intake were the Fe intake frequency index and the food group score. The Fe index showed significantly positive correlation with the pre-pregnancy food intake and the food group score. Hb showed a significantly positive correlation with the pre-pregnancy food intake. We concluded that strategies to improve iron status be implemented in the pre-pregnant stage so as to reduce the prevalence of iron deficiency and that we should stress on the importance of an adequate diet as well as the maintenance of a heathy weight.

The dietary vitamin $B_6$ intake of 218 Korean young women (aged 20-26y), who had no health problems, and their sources were estimated using a modified Korean vitamin $B_6$ database. The average daily vitamin $B_6$ intake was 0.987 mg for the subjects. About 87.2% of the subjects consumed less than the Korean Recommended Dietary Allowance (RDA) of vitamin $B_6$. The average ratio of vitamin $B_6$ intake to daily protein intake was 0.014 mg/g protein, and approximately 91% of subjects consumed 〈 0.02 mg/g protein. Vitamin $B_6$ intake was significantly (p〈.01 -p〈.001) positively correlated to the intakes of all other nutrients. Between animal and vegetable protein, animal protein had a stronger positive correlation with vitamin $B_6$. Major dietary sources of vitamin $B_6$, the top 10 foods provided nearly 64% of total vitamin $B_6$, and dietary contributors of vitamin $B_6$ for Koreans are less varied than those for Americans.

Three-day dietary records data from 237 college students(male 65, female 172) were used as the basis to estimate total dietary fiber(DF) intake of Korean adults & to investigate the major food sources of fiber. Mean daily DF intake of the subjects was 15.2$\pm$3.7g range being 7.5-34g When related to energy intake women consume more DF(7.7$\pm$1.5/1000kcal) than men(6.8$\pm$1.7g/1000kcal) Mean daily crude fiber(CF) intake of the subjects was 6.2$\pm$2.4g The mean DF:CF ratio for the subjects was 2.5$\pm$0.5 indicating that DF intake is 2-3 times of CF intakes The intakes of the two measures of fiber were highly correlated(r=0.791) The major food sources for DF in Korean are vegetables cereals and fruits and 14.3% respectively In comparision with limited international data on the DF intake by adults DF intake by the subjects was similar to those of developed countries. Present study indicates that DF intakes of the subjects are considerably lower than recommended level and they need to consume more DF than the present level.

This research was conducted to evaluate the general dietary quality(the balance and diversity of food intake, nutrient intake and adequacy) of 12 to 36-month-old toddler, through examining their actual food intake. It was conducted for 664(male-357, female-307) healthy toddler who were outpatients from Mar. to Aug., 1999 at university hospitals and private hospitals in Seoul and kyunggi province. The anthropometric parameters were measured. The 24-hr recall method were utilized to analyze the nutrient intake by months, based on the classification of The Korea Child Gorwth Standard. As for the subjects of this research, we found that the younger the age, the more frequent the pattern of intake of only 3 kinds of food groups. The results are that 1) the group with 1 point of the DDS(Dietary Diversity Score) mostly took only foods from the milk group, 2) the group with 2 points only took foods from the grain and milk group, 3) the group with 3 points did not take foods from the fruit and vegetable group, and 4) the group with 4 points took just about all kinds of food groups except for the vegetable group. This means that most of them were not taking various kinds of food even after the age of 12 months, and that they took more than twice the recommended amount of foods from the milk group until the age of 20 months. Thus, one could find a tendency of dependance on the milk group for food intake. Food intake for the vegetable group was severely under the recommended allowance, regardless of the age. The intake of iron was less than two thirds of the recommended allowance, except for the group of 12 to 14-month-olds who had been fed with infant formula. The Nutrient Adequacy Ratio(NAR) of major nutrients(protein, calcium, phosphorous, iron, vitamin A, vitamin B$_1$, vitamin B$_2$, niacin, vitamin C) and the Mean Adequacy Ratio(MAR, shows the general quality of dietary intake) was 0.86$\pm$0.12, but the NAR of iron was 0.62$\pm$0.27, which was extremely low compared to those of other nutrients. Therefore, concerning the subjects of this research, the MAR value alone does not provide enough ground to conclude that the subjects dietary quality is satisfactory.

This study investigated nutritional status and eating behaviors among 59 nephritic patients with mild kidney malfunction in Korea. Nutritional status was measured by blood analysis and 1-3 day dietary recall and records, and eating behaviors were assessed by a questionnaire. Mean Body Mass Index(BMI) was within the normal range, while 21% and 14% of the patients were underweight and overweight, respectively. They received nutrition information mainly from doctors, nurses and mass media, but rarely from nutrition professionals. A quarter of patients skipped breakfast at least 3 times per 12% of the patients, respectively. Energy intake of 83% of the patients was less than the recommended level. Protein intakes of 56% of them were either under or over the recommended levels. Patients had low vitamin B$_2$ and calcium(<75% of the RDA) and excessive phosphorus(138% RDA) and vitamin C(170% RDA). Major food sources to absolute nutrient intakes were similar to those for the average Koreas, except for milk. Milk intake was low in our patients. Dietary quantity and quality were associated positively with BMI, albumin, and HDL-cholesterol and negatively with triglycerides and BUN. Results of this study indicate low nutritional status of the patients and, in turn a need for conducting nutritional education or counselling at regular at regular basis for the nephritic patients with mild kidney malfunction.

In order to investigate the protein intake of breast-fed infants, we examined sixty infants during the first 5 months of lactation. Human milk intake infants increased during lactation with the respective values of 525, 671, 734, 744 , 765 and 768g/day t 0.5, 1, 2, 3, , 4 and 5 months postpartum. The average protein contents of human milk showed 1.58, 1.38, 1.23, 1.11, 1.08and 1.07g/100g respectively. The protein intake of boys during the first 5 months of lactation averaged 9.11g/day which was higher than the 7.71g/day average for girls. Body weight of infants at birth was 3337g, which increased significantly during lactation. The protein intake per body weight of breast-fed infants in boys was significantly higher than that in girls(p<0.01). Protein intake of breast-fed infants had survey, a revaluation of the protein intake and recommended dietary allowance of protein during early infancy should be considered.

To assess the dietary fiber intake of preschool children in Busan and to evaluate the relationship between of the intake of dietary fiber and nutrient intake. Nutrient intake using 24 hour recall, and total dietary fiber (TDF) intake based on tables of TDF of common Korean floods developed by the modified Prosky Method, were estimated for 176 preschool children. The mean daily intakes of TDF, and TDF after adjusting energy intake, were 10.20 g and 7.69 g/1,000 kcal, respectively. The mean daily intakes of TDF for children aged 1-3 and 4-6 years were 9.20 g and 11.08 g, respectively. The range of TDF intake was 1.86 to 22.16 g. The major sources of TDF were cereals (31.0%), vegetables (18.9%) and fruits (11.9%). The TDF intake showed positive correlations with nutrient adequacy ratios (NAR) of iron and Vitamin $B_1$, (p < 0.05, p < 0.05). The TDF intake per 1,000 kcal showed negative correlations with the NARs of protein, calcium, phosphate, iron, Vitamin A, vitamin $B_1$, Vitamin $B_2$, and niacin (p < 0.001, p < 0.001, p < 0.001, p < 0.05, p < 0.001, p < 0.001, p < 0.001, p < 0.001) and with the mean adequacy ratio (MAR, p < 0.001). When children were stratified into quartiles ($Q_1-Q_4$) on the basis of their fiber intake per 1,000 kcal, their NARs for calcium, phosphate, iron, Vitamin A, Vitamin $B_1, Vitamin $B_2$ and niacin (p < 0.05, p < 0.05, p < 0.001, p < 0.05, p < 0.05, p < 0.001, p < 0.001), and their MAR (p < 0.001) were significantly lower in the children with higher fiber intake per 1,000 kcal (the upper quartile). The NARs fur calcium (0.63), iron (0.60), Vitamin A (0.66), Vitamin $B_2$(0.74), niacin (0.64), Vitamin C (0.65) and the MAR (0.74) were lower than 0.75 in the children with fiber intakes of more than 9.25 g per 1,000 local (0,), the highest fiber intake per 1,000 kcal. Based on these results, the mean TDF intake of children was higher than the age (yr)+5g , the minimum recommended level for American children. Meals with a fiber intake of more than 9.25 g per 1,000 local ($Q_4$) could cause a decreased nutritional status for minerals and vitamins. The result of this study could contribute to the establishment of Recommended Dietary Allowances (RDA) for dietary fiber for Korean Preschool children.

The purpose of this study was to investigate the effects of dietary behavior on the nutritional status of university students in Korea. A dietary intake survey of 603 university students (223 males and 380 females) was conducted using a 24-hour recall method. The resulting data on dietary behavior and nutrient intakes were analyzed by the SAS program package. The main results were as follows : 1) Most of the subjects were in their twenties and no obese cases were found. 2) Dietary intake data showed that, except for vitamin C in the female students, the average daily intakes of most nutrients did lot meet the Korean Recommended Dietary Allowances (RDA). The study also showed that most of the subjects, especially the female students, were concerned about having satisfactory physical appearances. Fat provided 25% of the daily energy intake, and this level was higher than the 20% recommended by the Korean Dietary Guidelines. In the female students, the iron intake from animal foods was lower than that from plant foods. 3) Male students were not very serious about healthy eating. However, the female group, who obtained a high score in dietary behavior, consumed more vegetables and had higher intakes of energy, protein, Ca, p, vitamin A, and vitamin C than the male group, even though they did not meet the Korean RDA in most nutrients. Energy intake from fats, as a percent of total energy intake, was lower than in the group of females who obtained higher stores in dietary behavior than the other groups. To sum up, the university students surveyed in this study were found to have the typical dietary behavior of young adults, such as frequent eating out and snacking. Female students were extremely conscious of their body images this can exert an important direct influence on their dietary intakes and health status. It is very important for university students to develop healthy lifestyles and desirable dietary behaviors, to best enable them to continue to lead a healthy lift: in their later years.
