Purpose: This study was conducted to update the Nutrition Quotient for Adolescents (NQA), which is used to assess the overall dietary quality and food behavior among Korean adolescents. Methods: The first 30 candidate items of the measurable eating behavior checklist were obtained based on a previous NQ-A checklist, the results of the seventh Korea National Health and Nutrition Examination Survey data, Korea Youth Risk Behavior Survey data, national nutrition policies and dietary guidelines, and literature reviews. A total of 100 middle and high school students residing in Seoul and Gyeonggi Province participated in a pilot study using the 25-item checklist. Factor analysis and frequency analysis were conducted to determine if the checklist items were organized properly and whether the responses to each item were distributed adequately, respectively. As a result, 22 checklist items were selected for the nationwide survey, which was applied to 1,000 adolescent subjects with stratified sampling from 6 metropolitan cities. The construct validity of the updated NQ-A 2021 was assessed using confirmatory factor analysis. Results: Twenty checklist items were determined for the final NQ-A 2021. The items were composed of three factors: balance (8 items), moderation (9 items), and practice (3 items). The standardized path coefficients were used as the weights of items to determine the nutrition quotients. NQ-A 2021 and 3-factor scores were calculated according to the weights of questionnaire items. The weight for each of the 3 factors was determined as follows: balance, 0.15; moderation, 0.30; and practice, 0.55. Conclusion: The updated NQ-A 2021 is a useful instrument for easily and quickly evaluating the dietary qualities and eating behaviors of Korean adolescents.

혈당 조절에 미치는 올리고당의 acarbose의 효과

김혜영 A 龍仁大學校 2002 용인대학교 논문집 Vol.21 No.-

In Korea, 2.5% of population have diavetes mellitus. The prevalencehas increased dramatically in recent years and one out of ten people over 65 years old have diabetes mellitus. Decreased physical activity, increased obesity, and changes in food consumption have been implicated in this epidemic. Oligosaccharide improves the intestinal microflora and increases the activity of bifidobacteria. It also has effects on blood cholesterol and triglyceride levels. Oligosaccharide ingestion does not stimulate insulin secretion of pancreas and no blood glucose increase was found. Oligosaccharide supplementation to diabetic patients reduced the symptom of constipation and decreased blood glucose for 2.5%. Acarbose is a pseudo-tetrasaccharide and is allowed as a drug for type Ⅱ diabetes in FDA. Acarbose is a competitive inhibitor of α-glucosidase enzyme. It reduces postprandial hyperglycemia. It also decreases serum insulin and triglyceride. In clinical study, acarbose ingestion decrease fasting blood glucose to 10-20 mg/dl and glycosylated hamoglobin to 0.5-1.0%. Oligosaccharide and acarbose both can show flatulence, diarrhea, and abdominal pain as an adverse effect. Therefore, adequate dosage should be used to maximize thebeneficial effect.

Purpose: This study was performed to evaluate the dietary nutrient intake status and hair mineral content of Korean young children.Methods: Fifty-five children who visited Seoul National University Bundang Hospital were divided into three groups by age: infants, toddlers, and preschoolers. The 24-hour recall method was used to collect the food intake data of the subjects. Hair mineral analysis was conducted using a Mass Spectrometer. Serum iron, ferritin, and calcium were also measured. Results: The mean energy intakes of the subjects were 730.3 kcal, 994.3 kcal, and 1,482.9 kcal for each age group. The mean percentage of energy intake compared to recommendation was 101.4% and was not different by age group. Toddlers of 37.8% and preschoolers of 54.5% consumed less than the Estimated Average Requirement (EAR) of calcium. Infants of 28.6%, toddlers of 10.8% and preschoolers of 9.1% consumed less than the EAR of iron. In the case of zinc, copper, and selenium, only 0% to 5% of toddlers and none of the preschoolers consumed less than the EAR of those minerals. The hair calcium, iron and copper concentrations were lower in toddlers and pre-schoolers than those in infants. Serum calcium levels of preschoolers were significantly lower than those of infants, whereas serum iron and ferritin levels were not.Conclusion: Hair calcium, iron, and copper concentrations were significantly lower in toddlers and preschoolers than in infants. Insufficient dietary intake of calcium and iron seems to be related with decreased hair mineral contents in young children.

The present study was designed to investigate serum lipid and iron status of female university students by body fat classes. Twenty five female college students were selected to examine height, weight and body fat percent. Fasting bloods were drawn from the subjects and serum lipid status and iron status were analyzed. For the lipid status, triglyceride and cholesterol were analyzed. For the iron status, hematocrit, hemoglobin, MCHC, serum iron, total iron binding capacity(TIBC) and ferritin level were analyzed. The height, weight and daily food intake of the heavy group(body fat>25%) were similar with those of the normal group(body fat≤25%) Therefore, the body fat percent difference between two groups seems due to the difference in daily activity level. The daily iron and calcium intakes of the subjects were very low and those were only 60-70% of the korean recommedations. Mean triglyceride and cholesterol levels of the subjects were 90.1mg/dl and 170.6mg/dl, respectively. The heavy group had significantly lower cholesterol value than the normal group(159.3mg/dl vs. 184.9mg/dl). The mean hematocrit, hemoglobin and serum iron levels were normal and were 42.6%, 14.2mg/dl, and 107.3㎍/dl, respectively. The mean TIBC of the subjects was a little bit high and it was 384.2㎍/dl. Transferrin saturation and serum ferritin concentration were also normal and were 29.1% and 24.8㎍/l. Meanwhile, the heavy group had slightly higher hematocrit, hemoglobin, transferrin saturation, serum ferritin, and had lower TIBC compared to the normal group. Therefore, normal body fat is proper to prevent lipid related diseases in the elder life, but is probably bad to keep away from iron deficiency.

이현숙,장문정,김혜영A,심지선,이정숙,김기남 한국영양학회 2018 Journal of Nutrition and Health Vol.51 No.2

Purpose: This study was performed to evaluate the utilization of a current national Food Composition Database (FCDB) and to investigate demand for nutrients that should be added or supplemented in order to expand the national FCDB. Methods: Surveys were constructed based on the utilization of FCDB, use of a food and nutrition analysis program, utilization and importance of nutritional ingredients, and nutritional ingredients desired to be supplemented in the national FCDB. Self-administered surveys were obtained from 349 food and nutrition specialists, including dietitians, nutrition teachers, food industry workers, professors, and researcher. Results: Exactly 73.6% of respondents used the FCDB, and 90.5% experienced using various food and nutrition analysis programs. Professors and researchers frequently utilized protein, carbohydrate, and lipid nutrients in the FCDB. Among vitamins, vitamin C, vitamin A, and vitamin D were frequently used. Among minerals, sodium and calcium were highly used. Among the subjects, 17.4% of subjects have used phytochemical DB. Carotenoids, anthocyanins, and isoflavones among phytochemicals were frequently used, in that order. Respondents desired an additional data on sugars, vitamin D, folic acid, selenium, iodine, dietary fiber, vitamin B12, and carotenoids in the FCDB. Conclusion: The survey results indicate that the current FCDB is actively used for various purposes, although it is necessary to construct a national nutrition database with additional nutrients. 본 연구는 영양사와 영양교사, 식품업계 종사자, 식품영양학과 교수와 연구자 등 총 349명의 식품영양전문가들의국가식품영양성분 DB에 대한 활용 현황과 요구도를 조사하고, DB 구축 및 갱신 시에 보완과 추가가 필요한 영양소를 선정함으로써 효율적인 식품영양성분 DB 구축을 위한방안을 제시하고자 하였다. 본 연구 결과는 다음과 같다. 1. 현재 사용되고 있는 모든 식품영양성분 DB들에 대한영양전문가들의 사용 경험 즉, 활용도는 약 73.6%로높았고, 특히 식품영양 연구자군이 97.8%로 가장 높았다. 2. 식품영양성분 DB를 활용한 프로그램의 사용경험은90.5%로 식품영양성분 DB 자체를 사용한 경험보다더 높게 나타나, DB 자체 보다는 DB를 활용하여 개발한 프로그램에 대한 사용의존도가 더 높음을 알 수있었다. 3. 식품영양성분 DB의 각 영양성분별 활용도를 조사한결과, 활용도가 높은 영양소는 단백질, 탄수화물, 지질이었고, 비타민 중에서는 비타민 C, 비타민 A, 비타민 D가, 무기질 중에서는 나트륨과 칼슘의 활용도 가 높았다. 반면, 개별 아미노산과 개별 지방산, 토코트리에놀, 망간, 황, 불소 및 크롬의 활용도는 낮았다. 4. 조사대상자의 직종별로 영양성분 활용도를 비교한결과 식품영양 연구자군은 모든 영양성분에 있어 전반적으로 활용도가 높았고, 특히 식이섬유와 비타민A, 엽산, 비타민 C, n-3 지방산, 콜레스테롤, 레티놀, 베타카로틴, 비타민 E와 토코페롤, 비타민 B2, 니아신과 비타민 B6의 활용도가 다른 직종에 비해 높았다. 5. 피토케미컬 DB를 활용한 경험은 전체 대상자 중17.4%이었고, 식품영양 연구자군이 33%, 식품산업체종사자군이 18.8%, 영양사 및 영양교사가 14.5%의활용도를 보이는 것으로 나타났다. 피토케미컬 중에서 카로티노이드류, 안토시아닌류, 이소플라본류의순으로 DB 활용도가 높았다. 6. 식품영양성분 DB의 영양소별 중요도는 활용도 조사결과와 유사한 경향을 보였고, 모든 영양성분별 중요도 점수가 5점 만점에 3점을 상회하여 대체로 보통이상의 중요도를 가진 것으로 평가하였다. 7. 앞으로 식품영양성분 DB에 보완 또는 추가되기를 희망하는 영양성분은 당류와 비타민 D, 엽산, 셀레늄, 요오드, 식이섬유, 비타민 B12, 카로티노이드류 등으로나타났다. 이상의 결과로 볼 때, 각 정부 부처의 노력으로 구축된한국의 식품영양성분 DB는 여러 가지 목적으로 활용되고있는데, 급변하는 사회에서 필요로 하는 영양정보를 얻기위해 보다 완성도 높고 다양한 영양소가 보완된 국가식품영양성분 DB 구축에 대한 요구가 큰 것으로 파악되었다. 앞으로 다양한 분야의 소비자를 대상으로 한 요구도 조사가 이루어질 필요가 있으며, 이를 DB 개선에 반영해야 할것으로 보인다.

한국인의 비만 인식 정도, 체중 조절 및 만족도

김혜영(A) 용인대학교 자연과학연구소 2004 自然科學硏究所論文誌 Vol.9 No.1

Body weight is affected not only by one's genetics, but also by one's culture, history and many social characteristics. In 1998 Korean national survey, 55.2% of adult men (40-49 years old) were overweight and 56.9% of adult women (50-59 years old) were overweight. The reason of dieting was different by age group. People under 30 years of age did do diet for good-looking, but elder people did do diet to improve their health. Many college students had wrong perception on their body weight. The more over weight people used more diet methods, but the degree of satisfaction was lower than the others. Many young women are suffering from poor nutrition status, severe body weight change and eating disorder due to a poor dieting methods. The change of paradigm is necessary in dieting. The body weight control should be done to improve one's health rather than to escape from obesity.

The trend of safety control and labelling regulation of genetically modified food in several countries are investigated. Genetic engineering allows simple genetic traits to be transferred to crop plants from wild relatives or virtually any other organism. Genetically modified foods offer a way to quickly improve crop characteristics. Traitsachieved by genetic rnodification prirnarily involve herbicide tolerance and insect pest resistance Meanwhile, the risk of genetically modified organism (GMO) include unanticipated allergic responses to foods, the spread of pest resistance or herbicide tolerance to wild plants. The safety assessment of GMO are based on the synthesis or increase of unanticipated toxic material, changes in essential nutrient level, risk of food allergies, and development of antibiotic resistance. In Korea, Japan and Europe, GMO labelling system has been in force for the consumer's right to know and for an offer of choice Soybean, corn, bean sprouts and potato are the subject of investigation in Korea at this time. The development of better assessment ecchnique of GMO is necessary and the fast and right information of GMO should be delivered to the consumers
