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.

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.

Purpose: This study was undertaken to revise and update the Nutrition Quotient (NQ) for Korean adults, a tool used to evaluate dietary quality and behavior. Methods: The first 31 items of the measurable food behavior checklist were adopted based on considerations of the previous NQ checklist, recent literature reviews, national nutrition policies, and recommendations. A pilot survey was conducted on 100 adults aged 19 to 64 residing in Seoul and Gyeonggi Province from March to April 2021 using a provisional 26- item checklist. Pilot survey data were analyzed using factor analysis and frequency analysis to determine whether checklist items were well organized and responses to questions were well distributed, respectively. As a result, the number of items on the food behavior checklist was reduced to 23 for the nationwide survey, which was administered to 1,000 adults (470 men and 530 women) aged 19 to 64 from May to August 2021. The construct validity of the developed NQ (NQ-2021) was assessed using confirmatory factor analysis, linear structural relations. Results: Eighteen items in 3 categories, that is, balance (8 items), moderation (6 items), and practice (4 items), were finally included in NQ-2021 food behavior checklist. ‘Balance’ items addressed the intake frequencies of essential foods, ‘moderation’ items the frequencies of unhealthy food intakes or behaviors, and ‘practice’ items addressed eating behaviors. Items and categories were weighted using standardized path coefficients to calculate NQ-2021 scores. Conclusion: The updated NQ-2021 appears to be suitable for easily and quickly assessing the diet qualities and behaviors of Korean adults.

Purpose: This study was undertaken to update the Nutrition Quotient for Elderly (NQ-E), which reflects dietary quality and behavior among Korean older adults. Methods: The first 29 items of the measurable food behavior checklist were obtained from a previous NQ-E checklist, recent literature reviews, and national nutrition policies and recommendations. One-hundred subjects (50 men and 50 women) aged ≥ 65 years living in the Seoul Metropolitan Area, including Gyeonggi Province, completed a pilot survey from March to April 2021. Based on the results of the pilot study, we conducted factor analysis and frequency analysis to determine whether the items of the survey were properly organized and whether the distribution of answers for each evaluation item was properly distributed. As a result, we reduced the number of items on the food behavior checklist and used 23 items for the national survey. Nationwide, 1,000 subjects (472 men and 528 women) aged > 65 years, completed the checklist survey, which was applied using a face-to-face survey method from May to August 2021. The construct validity of the NQ-E 2021 was assessed using confirmatory factor analysis, LISREL. Results: Seventeen food behavior checklist items were selected for the final NQ-E 2021. Checklist items addressed three factors: balance (8 items), moderation (2 items), and practice (7 items). Standardized path coefficients were used as the weights of items to determine nutrition quotients. NQ-E and three-factor scores were calculated according to the weights of questionnaire items. Conclusion: The updated NQ-E 2021 produced by structural equation modelling provides a suitable tool for assessing the dietary quality and behavior of Korean older adults.

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.

Purpose: The purpose of this study was to determine whether the dietary quality of food consumed by the elderly is influenced by the consumption of healthy functional foods using Nutrition Quotients for the Elderly (NQ-E). Methods: The study subjects were 250 adults aged ≥ 65 living in Seoul or Gyeonggi-do. Those who had consumed healthy functional food for more than 2 weeks within the previous year were classified as healthy functional food consumers, and the quality of their meals was evaluated using the NQ-E. Statistical analysis was performed using SAS 9.4, and sex and age-associated differences were adjusted before comparing differences based on healthy functional food intake. Results: The average age of the study subjects was 70.8. The scores for each area and the Nutrition Quotient (NQ) score were as follows: balance 43.3 points, moderation 56.7 points, practice 65.7 points, and NQ 52.5 points. When comparing differences according to healthy functional food intake status, healthy functional food consumers had significantly higher balance and NQ scores than non-consumers. When considering each NQ item score, healthy functional food consumers had significantly higher scores than non-consumers for fruit, fish and seafood, eggs, nuts, and whole grain rice, and a higher score for effort to maintain a healthy diet. Conclusion: Dietary quality as assessed by Nutrition Quotients for the Elderly was better for healthy functional food consumers than non-consumers.

황예순,김혜영A 한국영양학회 2014 Journal of Nutrition and Health Vol.47 No.5

Purpose: This study investigated the eating behaviors of Chinese children using the Nutrition Quotient for Children (NQ-C). Methods: The research subjects were 336 students (166 boys and 170 girls) in the 5th and 6th years at two elementaryschools in Shandong Province and Jiangsu Province. Results: The average score of the Children's NQ was good, reaching69.6 points. The factor scores for balance, moderation, diversity, regularity, and practice were 58.8, 84.9, 63.6, 76.1, and73.6 points, respectively. Compared with the diagnostic cut-off points of the factors, mean balance, moderation, regularity,and practice scores were above the cut-off points, but diversity score did not meet the cut-off points. Fathers' educationlevel showed positive correlation with the balance, regularity, and NQ scores of the students. Mothers' education level alsoshowed positive correlation with the balance and regularity scores and mother's employment showed positive correlationwith regularity score. As the exercise hours per day increased, the NQ score also increased. Conclusion: The questionnaireof NQ-C developed in Korea can be used in assessment of nutrition behavior of Chinese elementary students who havesimilar eating patterns. 본 연구는 한국영양학회·한국암웨이에서 2012년에 개발한어린이영양지수 (NQ-C, Nutrition Quotient for Children) 설문지를 이용하여 중국 산동성과 강수성 지역 초등학교5, 6학년어린이 336명 (남학생: 166명, 여학생: 170명)의식행동을 살펴보고자 수행하였고, 그 결과를 요약하면 다음과같다. 1) 어린이의 평균 영양 지수 (NQ) 점수는 백점 만점에69.5점으로 양호한 수준이었고, 성별에 따른 차이는 없었다. 개별영역별로는균형점수 58.8점, 절제점수 84.9점, 다양점수 63.6점, 규칙점수 76.1점, 실천점수 73.6점으로나타났다. 영역별 진단기준치와 비교해볼 때, 어린이들의 평균균형, 절제, 규칙, 실천 점수는 기준치에 비해양호한편이었으나, 다양점수는진단기준치에미치지못하였다. 2) 어린이 영양지수의 최상위 등급은 13.7%, 상위등급은23.5%, 중위 등급은 50.3%, 하위는 9.5%, 최하위 등급은3.0%로 나타나서 최상위와 상위 등급의 비율이 기대치인10%와 15%를 넘었고, 반면 하위와 최하위 등급의 비율은기대치보다 더 적어서 바람직한 모습을 보였으며, 남녀 간의유의차는없었다. 3) 아버지의 학력은 어린이의 균형 점수, 규칙 점수와 상관성이 있었고, NQ 점수와도 유의적인 양의 상관관계를보였다. 어머니의 학력도 아버지와 비슷하게 균형 점수, 규칙점수와 양의 상관관계를 보였고, 어머니가 취업을 한경우어린이의규칙점수가더높은것으로나타났다. 4) 조사대상자의 1일 운동 시간이 증가할수록 NQ 점수가 유의적으로 높았고, 하루에 1시간 이상 운동을 하는 학생들은 운동을 하지 않는 학생들보다 균형, 다양, 규칙, 실천영역의점수가유의적으로높았다. 본 연구의 결과를 종합해 볼 때, 중국 중소도시 어린이의영양지수 평균 점수는 69.5점으로 양호하였고, 균형, 절제, 규칙, 실천 점수는 양호하지만, 다양성 점수는 개선이 필요한 것으로 나타났다. 한국에서 개발된 어린이 영양지수(NQ-C) 설문지는 비슷한 생활 패턴을 가진 중국 초등학생의식행동 실태 평가에 활용이 가능한 것으로 사료되며, 조사대상 지역에 따라 영양지수 점수와 영역별 점수가 다르게 나타나므로, NQ-C를 활용한 영양상태 평가 후에 각 지역에 맞는 영양교육 프로그램을 개발하는 것이 필요하다고사료된다.

Purpose: This study was conducted to investigate the effects of an education program using a high-fidelity simulator of labor and delivery on nursing knowledge, critical thinking, and clinical performance among nursing students who had not yet experienced clinical practicum. Methods: The development of a 5-week maternity nursing education programs using high-fidelity simulators included modules containing case-oriented scenarios, knowledge, and skills required for maternity care. A randomized controlled study was conducted to verify the effects of the developed program. Data were collected from October 21 to December 9, 2019. The experimental group (n=36) participated in a 5-week high-fidelity simulation program on care for the woman in labor, whereas the control group (n=36) received standard education as lecture and practice with delivery model. The collected data were analyzed using descriptive statistics (frequency, percentage, mean, and standard deviation), the Chi-square test, Fisher exact test, and t-test. Results: For participants who received education using the high-fidelity simulation program, nursing knowledge (t=2.33, p=.011), critical thinking (t=3.73, p<.001), and clinical performance (t=2.53, p=.006) were significantly higher than in the control group. Conclusion: Even for students with no clinical experience, high-fidelity simulation-based nursing education was effective in improving nursing knowledge, critical thinking, and clinical performance among nursing students. Nurse educators will be able to use this high-fidelity simulator effectively, especially in situations where direct clinical practicum may not be feasible.
