A food frequency questionnaire (FFQ), which can be used in studies investigating relationship between diet and chronic diseases in a rural area of Korea, was developed and validated. Food items were selected from two sources ; (1) preliminary survey in a rural area by 24-hour recalls and (2) National Nutritional Survey of 1991. Sixty-five food items were finally selected based on the frequency of consumption and contributions to major nutrient intakes. Portion size of each food item was determined considering the mean and median values of the amounts consumed by subjects in the preliminary survey. Frequency of consumption was asked in nine categories ranging from 'more than three times a day' to 'almost never'. The newly developed FFQ was administered in 24-hour recalls conducted in different seasons in the same area after the administration of FFQ. Sixty-one subjects completed both FFQ and all three repeated 24-hour recalls. The results of the two different survey methods showed that mean daily intake levels of energy, carbohydrate, vitamin A and vitamin C were significantly higher in FFQ compared to 24-hour recalls(p<0.05). Intake levels of energy, protein, fat, carbohydrate and iron were significantly correlated by Pearson's correlation coefficients(p0.05). Ranking on nutrient intake of the subjects by two method were significantly correlated(Spearman's correlation coefficients) in all above nutrients plus Ca and vitamin A. Percentage of subjects in the lowest or in the highest quintile by 24-hour recalls who belong to the nearest two categories by FFQ ranged from 46% to 83%, while the percentage falling into the opposite category were below 10% in most of the nutrients. The proportion of subjects classfied into the same quintiles by the two methods were between 23% and 33%, with an average of 28%. From the results, FFQ developed in this study seems to be useful in evaluating nutrient intake pattern of 1 year in adults living in rural area of Kyonggi province.

The purpose of this study was to evaluate nutrient intake and anthropometric parameters related to obesity in Korean female adolescents according to dietary diversity score. We analyzed data from the combined 2007-2009 Korean National Health and Nutrition Examination Survey (KNHANES). The subjects were 770 female adolescents. Nutrient intakes, Dietary Diversity Score (DDS) ) and Dietary Variety Score (DVS) were derived by using the data from the 24-recall method. The DDS was defined as the number of six food groups (cereals, meats, fruits, vegetables, dairy, fats and oils) consumed. The DVS was defined as the number of food items consumed. The average age of the subjects of the study was 15.02 years and the average height, weight, and BMI were 159.50 cm, 52.58 kg, 20.62 kg/$m^2$, respectively. The energy and nutrients intakes, percent of the recommended intake for nutrients in DDS = 5~6 group were significantly higher than those of the other groups. Calcium and vitamin C INQ in DDS = 5~6 group were significantly higher than those of the other groups. The average DVS of the subjects was 29.33. The most frequent style of food pattern was CMDFVO (cereals, meats, dairy, fruits, vegetables, fats and oils) = 111011. In conclusion, in healthy Korean female adolescents, food diversity intake variety did beneficially affect the intakes of calcium and vitamin C. Further studies are needed to confirm these findings.

BACKGROUND/OBJECTIVES: In times of disaster, simplified and minimized nutritional standards are necessary for a quick response to provide nutritious relief food. This study aimed to develop nutrient-based nutritional standards for foodservice at shelters during disasters in the Republic of Korea (South Korea). SUBJECTS/METHODS: The standards were developed in 2 phases. First, nutrients to be included in the standards were selected. Initial candidates were selected considering 3 aspects: preceding standards, insufficient intake during disasters, and inadequate intake among South Koreans. Final selection was made by excluding nutrients for 3 reasons: nutrients for which there is no deficiency concern in South Korea, nutrients whose intake data were not available, or nutrients whose values presented by Dietary Reference Intakes for Koreans are difficult to achieve based on the current diet among South Koreans. Second, the reference values of energy and the selected nutrients were calculated. The reference values for the entire population who were 1-year-old and over were calculated by multiplying the estimated energy requirements or the recommended nutrient intake and the proportion of each age and sex group. Respective reference values were also calculated for 4 different age groups (1-5, 6-11, 12-64, and ≥ 65-year-old). RESULTS: The standards for the entire population were 2,000 kcal for energy, 55 g for protein, 650 ㎍ retinol activity equivalents for vitamin A, 95 mg for vitamin C, 1.1 mg for thiamin, 1.3 mg for riboflavin, 14 mg niacin equivalents for niacin, 350 ㎍ dietary folate equivalents for folic acid, 750 mg for calcium, and 11 mg for iron. Four additional standards corresponding to each age group were developed. CONCLUSIONS: The nutritional standards during disasters were developed for South Korea, including energy and 9 nutrients with reference values for the entire population and 4 different age groups. The standards will contribute to maintaining the health of disaster evacuees in South Korea.

BACKGROUND/OBJECTIVES: The aim of this study was to examine differences in nutrient intake and food consumption by the presence of metabolic syndrome in Korean adults. SUBJECTS/METHODS: Study subjects in this cross-sectional study were recruited from four outpatient clinics in and near the Seoul metropolitan area of South Korea between 2006 and 2012. A total of 668 subjects (413 men and 255 women) aged ${\geq}30y$ were included in the final data analyses. For each subject, daily nutrient intake and food consumption were calculated using three days of dietary intake data obtained from a combination of 24-hour recalls and dietary records. To evaluate food consumption, mean number of servings consumed per day and percentages of recommended number of servings for six food groups were calculated. Metabolic syndrome was defined using the National Cholesterol Education Program Adult Treatment Panel III criteria. The general linear model was performed to examine differences in nutrient intake and food consumption by sex and the presence of metabolic syndrome after adjustment for potential confounding variables. RESULTS: Nutrient intake did not differ by the presence of metabolic syndrome in both men and women. Men with metabolic syndrome had lower consumption and percentage of the recommendation for fruits compared with those without metabolic syndrome (1.6 vs. 1.1 servings/day, P-value = 0.001; 63.5 vs. 49.5%, P-value = 0.013). Women with metabolic syndrome showed lower consumption and percentage of the recommendation for dairy foods than those without metabolic syndrome (0.8 vs. 0.5 servings/day, P-value = 0.001; 78.6 vs. 48.9%, P-value = 0.001). CONCLUSIONS: Low intakes of fruits and dairy foods might be associated with the risk of having metabolic syndrome among Korean adults. Dietary advice on increasing consumption of these foods is needed to prevent and attenuate the risk of metabolic syndrome.

In order to find the relationships of nutrient intakes and food consumptions to calorie intake for young and middle-aged men, a study was peformed using the data of Korean National HealthㆍNutrition Survey in 1998. Data from 659 young men (20 to 29 years) and 1,697 middle-aged men (30 to 49 years) were analysed for percent of recommended daily allowance (%RDA), index of nutritional quality (INQ) and nutrient adequacy ratio (NAR) in order to evaluate one's Quality and quantity. We found that energy and nutrient intakes were not significantly different between young and middle-aged groups. Their calorie and nutrient intakes were below their RDA. The most insufficiently consumed nutrient (less than 75% of RDA) was calcium followed by thiamin vitamin A, and calorie. The lacks of calorie, protein, iron, vitamin C, and niacin were more widely-spread in the twenties than the middle-aged. The mean nutrient adequacy ratio of the middle-aged was better than that of the young, even though some INQ were worse. Only for the subjects consumed sufficient energy, there were positive relations between grains, meats or alcoholic drinks to calorie level in middle-aged men but there were positive relations between broiled fish/shell or fats/oils to calorie level in young men. It seemed that both middle-aged men eating alcoholic drinks, broiled meat, and grains and young men eating cake/cookies, rice cake/potato cake, grains, and sugars could consume enough calorie with nutritional imbalance.

Objectives: This study examined the effects of nutrition education on the nutritional status, including eating habits and quality of life in gastric cancer patients undergoing a gastrectomy. Methods: Thirty one out-gastric resection patients at C University Hospital in Gwangju, Korea were enrolled in this study. The patients received an individualized nutritional counseling session, and the effects were assessed before and after a 3-month nutrition education intervention. Nutrition education for gastric cancer outpatients included the dietary guidelines (e.g., food intake), the level of nutrient intake, and nutrition support. Results: The patients had significantly improved serum albumin and hematocrit levels after nutrition education. Of the dietary habits, the meal time and amount of food compared to the first education were increased significantly. Of the changes in the food intake frequency, fish and meat, and vegetables and fruits intake were increased, but not at a statistically significant level. The score of eating habits related to the gastrectomy was improved significantly after nutrition education from 31.7 to 34.5. The composite scores for the quality of life were also improved significantly after the nutrition education program. Conclusions: The nutrition education for gastric cancer outpatients may be crucial and efficient for improving their lifestyle.

This study was peformed to assess the nutritional status of female nursing home residents by dietary intake. The subjects were 60 nursing home residents aged over 60 from 3 different nursing homes in Seoul, Cheonan and Chunchon. Dietary intake was assessed by 24-hr recall and nutrient intake was calculated using CAN-Pro and database for vitamin E established by authors. To establish vitamin E database, we analyzed vitamin E concentration using HPLC in several foods consumed frequently by nursing home residents. The results of nutrient intake were as follows; 1) Average daily intakes of energy, protein, phosphorous, iron, vitamin $B_1$ and niacin were higher than RDA, but calcium, vitamin $B_2$ and niacin of Chunchon were lower than RDA. 2) Intakes of protein, sodium and niacin of Cheonan residents were significantly higher than those of Seoul. 3) Intakes of phosphorous, potassium, vitamin $B_1$ and dietary fiber of Cheonan residents were significantly higher than Seoul and Chunchon. 4) Intakes of sodium and cholesterol of Seoul residents were higher than Cheonan and Chunchon. 5) Average daily intake of vitamin E was lower than RDA. Especially vitamin A intake of Cheonan residents was significantly lower than other two cities.

The purpose of this study was to compare nutrients intake, eating behavior, and health indices according to intake frequency of wheat-based foods, using results from the 2013~2015 National Health and Nutrition Examination Survey. Subjects were 882 men age 40~64. According to intake frequency of wheat-based foods per week, two groups (Low intake group (LG); less than four times, High intake group (HG); more than four times) were divided, and their percentages were 54.0% and 46.0% respectively. Frequency of consuming wheat-based foods per week was 4.80, and there was significant difference (p<0.001) in both groups. Intake frequency according to wheat-based foods was high in noodles, cookies, and breads. Daily energy intake was higher, approximately 630 kcal in HG than LG (p<0.001). Also, energy ratio of fat and protein was higher in HG. There were significant differences in nutrient density per 1,000 kcal of minerals and vitamins between the two groups (p<0.01, p<0.001), except calcium, phosphorus, and niacin. In dietary behavior, frequency of meals (daily) was significant. In total cholesterol and LDL-cholesterol of health indices, HG was higher than LG (p<0.01). Results of this study reveal that frequent intake of wheat-based foods has negative effect on nutrition and health.

본 연구에서는 엽산의 급원식품으로 보고된 식품 51종의 엽산을 분석하고, 값에 차이가 많이 있는 경우 엽산 데이터베이스를 수정하여, 수정한 데이터베이스로 어린이와 청소년의 엽산 섭취량을 추산하고 급원식품을 알아보고자 하였다. 대상자는 대전, 충청도 및 전라도에 거주하는 만 20세 미만 567명으로 비연속 2일 동안의 24시간 회상법에 의해 식품섭취조사를 실시하였다. 51종의 식품을 새롭게 분석하여 현재의 데이터베이스와 비교한 결과 현재 값의 18.7%~322.9%의 결과를 얻었다. 기존의 값이 실험한 두 값 사이에 있거나, 기존값과의 차이가 10% 미만인 경우에는 수정하지 않았으며, 그 외에 차이가 있는 40종은 새로운 분석값으로 수정하였다. 수정한 데이터베이스로 대상자들의 엽산 평균섭취량을 성별, 연령별로 나누어 계산한 결과 모든 연령층에서 평균 엽산 섭취량이 권장섭취량보다 높았으나 12~14세 남자와 12~19세 여자의 평균 엽산 섭취량은 권장섭취량보다 낮은 것으로 나타났다. 계란, 배추김치, 쌀, 귤은 모든 연령층에서 엽산 급원식품의 10위 안에 포함되었다. 본 연구에서는 일부 급원식품 51종만을 분석하였으나 한국인들이 자주 먹는 식품의 조리 후 엽산 함량을 분석하여 보완해 나감으로써 더 정확한 엽산 섭취량을 추산할 수 있도록 해야 할 것이다. 또한 12~19세 여자의 평균 엽산 섭취량이 다른 연령층에 비해 상대적으로 낮게 나타난 것을 볼 수 있었는데, 엽산은 성장기 및 가임여성에게 특히 중요한 비타민으로써 이들을 위한 엽산 영양교육이 이루어져야 할 것으로 생각된다.

This study was done to evaluate the nutritional status and the desirable time and period for making dietary records in male high school Taekwondo athletes. Nutrient and flood intake was investigated using dietary record method during usual training (UT, for 29 days) and special training (ST, for 17 days) periods in nine Taekwondo athletes. Nutrient intake by 7-d and 3-d dietary record were compared to the standard nutrient intake, which was computed from dietary record during total period of UT or ST. Total mean energy intake was 2278 kcal, 84% of RDA, and mean intakes of riboflavin, Ca and Fe were less than 77% of RDA. Mean intakes of energy, carbohydrate, protein, fat, cholesterol, thiamin, riboflavin, and P decreased during ST (p < 0.05 or p < 0.01). Mean intakes of vegetables and grains ware the highest in the two periods and following were beverages and instant floods in UT, and meats and fruits in ST. During ST, mean intakes of mushrooms, meats and their products, and instant floods decreased, and sugars and sweets increased (p < 0.05 or p < 0.01). The contribution of grains and their products, instant floods, and meats and their products to mean intakes of energy, carbohydrate, protein and fat were high. In snacks, the contribution of instant floods, breads and confections and beverages was high. During UT, cholesterol intake at weeks 1 and 3, and intakes of protein, fat, thiamin, riboflavin and niacin at week 4 by 7-d dietary record were different from their standard intakes (p < 0.05 or p < 0.01). Intakes of VA, Ca and Fe at week 1, and intakes of carbohydrates, cholesterol rind crude fiber at week 4 by 3-d dietary record were different from their standard intakes (p < 0.05 or p < 0.01). During ST, VC intake at week 5, and energy intake from carbohydrate and cholesterol intake at week 6 by 7-d dietary record were different from their standard intakes (p < 0.05 or p < 0.01). Cholesterol intake at week 7, and energy intake from carbohydrates and fat, and intakes of protein, fat, cholesterol and riboflavin by 3-d dietary record were different from their standard intakes (p < 0.05 o. p < 0.01). In conclusion, empty-calorie floods can be a main source of diet and snacks for Taekwondo athletes, and education about desirable nutrients and floods intakes is needed to help them control their weight. When investigating the nutritional status of Taekwondo athletes in the future, the 7-day or 3-day dietary record is desirable provided they are conducted in the milddle of each period artier distinguishing UT from ST period.
