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.

The present study was conducted to evaluate the dietary fiber intake of 130 subjects, that included 49 subjects(29 form Wonju, 20 from Kangnung) with diabetes mellitus, 23 hyperlipidemia patients, and 58 normal subjects. After the type and amount of foods that a subject took for one day were investigated using the 24-h recall method, the intake of various nutrients and dietary fiber were calculated using a program that already contained the information on dietary fiber contents. The results showed that diabetics from Kangnung who did not undergo dietary therapy had more fat intake that those from Wonju, hyperlipidemia patients, and normal subjects thus, had more energy intake. Also, the crude fiber intake in male and female diabetics from Kangnung were 8.43${\pm}$3.47g and 3.35${\pm}$3.29g, respectively, showing significantly high amounts compared to those of male and female diabetics from Wonju, hyperlipidemia patients, and normal subjects; however, the intake of crude fiber per 1,000 kcal in males and females was not significantly different among the four groups. Also, the dietary fiber intake(14.8-19.8g/day) and the dietary fiber intake per energy unit(7.7-10.9g/1,000kcal) were not significantly different between the four groups. The dietary fiber intakes of diabetics and hyperlipidemia patients were not significantly different from those in normal subjects, and these amounts were significantly lower than recommended levels. Thus, the methods of increasing dietary fiber intake, such as developing low-calorie, high-dietary fiber foods or additives, needs to be researched.

The calcium intake of elementary school students residing in Gyeongsangbukdo province from their school foodservice and milk program was evaluated. A total of 252 subjects (50.4% boys and 49.6% girls) were examined. A significant percentage of the total subjects (32.9%) reported skipping breakfast once or more per week, with the major reasons for skipping breakfast being a lack of time and appetite. A majority of the to-tal subjects (78.2%) participated in the school milk program. The type of milk consumed by the subjects was mainly white milk, with a milk intake mostly between one and two cups. Participants in the school milk program consumed over the recommended nutrient intake (RNI) of calcium, but non-participants consumed only 48.1% of the RNI (P<0.001). The calcium intake rate according to food cooking methods, from highest to lowest was in the order bap, twigim, jeon, jjim, and gui. Although the food intake rate of guk was low, the calcium intake rate by RNI was the highest for guk. On the other hand, the food intake rate of bap and kimchi was high, but their calcium intake rate by RNI was relatively low. These results show that non-participants in the school milk program are significantly deficient in calcium. Therefore, to improve the calcium nutrition for children, school lunch menus containing high calcium need to be developed and children should be encouraged to enter a school milk program.

The prevalence rate of thyroid dysfunction (hypothyroidism and hyperthyroidism) has increased within the Korean population and seems to be affected by iodine dietary habits. Some studies reported that the prevalence of thyroid dysfunction increase both in the area of iodine deficiency and excess. In this study, we tried to discover the difference in iodine intake, anthropometric measurements, and blood parameters between male subjects with or without subclinical thyroid dysfunction. A total of 5,249 subjects (Euthyroid: 4706, SubHypo: 454, SubHyper: 89) were used in this study. There were no significant differences in BMI, body fat, visceral fat, waist circumference, SBP, DBP, total cholesterol, HDL-cholesterol, LDL-cholesterol, TG, fasting serum glucose, HbA1c, alcohol intake, however significant differences were noticed in both age and smoking status. Through a food frequency questionnaire (FFQ), iodine intake per day was estimated. The average iodine intake was similar (SubHypo $392.9{\pm}279.0{\mu}g$, Euthyroid $376.5{\pm}281.7{\mu}g$, SubHyper $357.3{\pm}253.8 {\mu}g$) among groups. The main source of iodine intake was eggs (52.8%, 54.2%, 52.4%) followed by milk (16.3%, 15.8%, 17.8%), then sea mustard & sea tangle (12.4%, 11.9%, 11.6%). The prevalence of subclinical hypothyroidism and subclinical hyperthyroidism was higher in subjects whose intake was higher than the recommended nutrient intake (RNI). These results suggest that the excess consumption of iodine intake may act as one of the risk factors regarding thyroid dysfunction in Korea. Therefore, an adequate amount of iodine intake is necessary in order to prevent subclinical thyroid dysfunction and clinical thyroid dysfunction.

Purpose: This study was to determine the effects of calcium intake on bone mineral density (BMD) in pre and post menopause women and to provide basic data for enhancing bone health of middle aged women. Methods: A total of 700 middle-aged women living in Seoul and Geonggi Province were interviewed during the period from June 2003 through January 2004 to investigate their social. demographic and physiological characteristics, health and daily activity performance, and their dietary patterns, and bone mineral density was measured. The survey of dietary intake was 24 hour recalls, and the individual calcium intake was calculated using food frequency. Data of 618 subjects was used for the analysis. Of the calcium intake levels, BMD values of the subjects of 20% of high level. 60% of middle level and 20% of low level were analyzed and compared. Results: The level of calcium intake according to general characteristics of the subjects was significantly related to age (p=0.001), education levels (p=.003) and marital status (p=.001). The BMD of the lumbar vertebrae and femur of the subjects taking a high level of calcium showed significantly higher than that of the subjects taking a middle level and low level of calcium. Femoral T-score was also significantly higher in subjects taking a high level of calcium than that of those taking a middle level and lower levels of calcium. Lumber spine T-score was higher in the high level group than that of the middle level group. Conclusion: The study revealed that women taking a high level of calcium had better bone health. Therefore. calcium intake is extremely important in daily dietary intake so that the intake of calcium-rich foods is highly recommended.

The purpose of this study was to estimate the daily intake of vitamin A in Korean female university students. Vitamin A intake was estimated using an inconsecutive 3-day dietary intake survey from 481 young women. Vitamin A intake values were calculated based on the data in USDA database. Average age, height, and weight of the subjects were 20.05 years, 162.13 cm and 54.38 kg, respectively. The subject's average intake of energy was 1645.67 kcal. The mean vitamin A, retinol and ${\beta}$ carotene intakes were $908.35{\pm}863.18$ ug retinol equivalent/day, $199.19{\pm}166.00$ ug/day and $3872.59{\pm}4972.17$ ug/day, respectively. The 21.83% of the subjects consumed less than the Estimated Average Requirement (EAR) for vitamin A. And subjects consumed 141.69% of the Recommended Nutrient Intake (RNI) for vitamin A. Food groups consumed with high vitamin A content in our subjects included vegetables (423.96 ug RE/day), potato and starches (213.64 ug RE/day), cereals (62.60 ug RE/day), eggs (55.17 ug RE/day) and milks (53.45 ug RE/day). The major food sources of vitamin A were sweet potato, carrot, spinach, egg, and cereal, and the top 30 foods provided 89.57% of total vitamin A. Also animal-derived food provided 9.65% of the vitamin A intake from the top 30 foods. In conclusion, judging from RNI, the vitamin A intake of the Korean female university students in this study was generally adequate. The result of our study may be used as a basis for follow-up studies of vitamin A intake like assessment of vitamin A nutritional status or evaluation of carotenoid food sources in Korean young women.

BACKGROUND/OBJECTIVES: Calcium is important but deficient in diets of young adult women. This study aimed to examine if cognitive factors and eating behaviors differ according to calcium intake based on the Social Cognitive Theory. SUBJECTS/METHODS: Subjects were female college students in Seoul, Korea. Three hundred students completed the questionnaire regarding calcium intake, nutrition knowledge, outcome expectations, self-efficacy and eating behaviors. Data on 240 students were analyzed using t-test or ${\chi}^2$-test. Subjects were categorized into two groups, high calcium intake (HC, ${\geq}650mg/day$) and low calcium intake (LC, < 650 mg/day), according to recommended intakes of calcium for women aged 19-29 years. RESULTS: The LC group constituted 77.9% of total subjects. Nutrition knowledge was not different according to calcium intake. Three out of 12 outcome expectations items were significantly different between the HC and LC groups. Subjects in the HC group agreed more strongly with the practical benefits of consuming calcium-rich foods, including 'taste' (P < 0.01) and 'going well with other snacks' (P < 0.05), compared to those in the LC group. Negative expectations of 'indigestion' were stronger in the LC group than HC group (P < 0.001). Among self-efficacy items, perceived ability of 'eating dairy foods for snacks' (P < 0.001), 'eating dairy foods every day' (P < 0.01), and 'eating calcium-rich side dishes at meals' (P < 0.05) differed significantly between the HC and LC groups. Eating behaviors including more frequent consumption of dairy foods, fruits or fruit juice (P < 0.001), anchovy, seaweeds, green vegetables, protein-rich foods (P < 0.05), and less frequent consumption of sweets or soft drinks (P < 0.01) were significantly related to calcium intake. CONCLUSIONS: This study found that outcome expectations, self-efficacy in consuming calcium-rich foods, and eating behaviors are important in explaining calcium intake. Nutrition education needs to address practical benefits, reduce negative expectations of calcium-rich foods, increase self-efficacy, and modify eating behaviors contributing to calcium intake.

Objectives: This study was conducted to investigate the status of total sugar intake and contributing foods in Korea according to age groups. Methods: This study used 24-hour dietary recall data from the 8th Korea National Health and Nutrition Examination Survey (2019-2021) to investigate the nutritional and total sugar intake status among Koreans. A total of 18,338 research participants (≥3 years old) were included in this study. To analyze the types of foods contributing to total sugar intake, these foods were categorized into 15 types. Moreover, we examined the total sugar intake and ranked the most consumed foods by age groups (3-11 years, 12-18 years, 19-34 years, 35-49 years, 50-64 years, over 65 years). A survey procedure was employed for statistical analysis. Results: The energy intake ratio from total sugars was approximately 12%-15%, which was within the recommended range. However, the proportion of individuals consuming total sugar exceeding 20% of their total caloric intake is nearly 20%, raising concerns about excessive sugar consumption. Furthermore, the percentage of participants whose intake of sugar from processed foods exceeded 10% of their total calories was highest in the 12-18 age group at 37.1%, followed by the 3-11 age group at 35.2%, and the 19-34 age group at 34.0%. Carbonated drinks, cola, and cider were the primary foods consumed by children and adolescents (3-18 years old) and young adults (19-34 years old). For middle-aged and older adults, mixed coffee with sugar and cream was a prominent contributor to sugar intake. Conclusions: This study investigated sugar consumption patterns among Koreans, finding the principal foods contributing to this intake. Identifying these contributors is pivotal, given their potential impact on public health.

The present study was conducted to determine whether the food shortage situation in North Korea has affected its people differentially according to social class. We performed a literature search on North Korean books and documents on food and nutrition. We also conducted a mail survey on North Korean defectors to estimate the energy and nutrient intake and the practice of foraging for wild foods at the time of food crisis in North Korea. The subjects were 150 adults, 104 men and 46 women, aged 20 years and older, who resettled in the South Korea after the food crisis. The mean energy intakes for men and women were estimated to be 1,260 kcal and 980.6 kcal, respectively, which were far less than 2,900 kcal and 2,600 kcal, the intake levels recommended for North Korean men and women, respectively. Thirty seven percent of the subjects reported a lack of foods adequate enough for work and other daily activities, and fifty seven percent reported a routine use of wild foods such as roots, grass, stalks, and tree bark with an average of 4 items per day. Food consumption patterns on a typical day were different by social classes with the high class people consuming an affluent diet in the midst of a severe food shortage.
