Recently, there is growing interest in studying the dietary patterns that affect the risk of circulatory system diseases (CSDs). We investigated the relationship between CSDs and dietary patterns through a follow-up study in Korea (2001-2016). The participants of this study were obtained from the Korean Genome and Epidemiology Study (KoGES). This study was a large community-based cohort study (the Ansan-Ansung areas) conducted to assess the effects of various factors, especially diet, on the onset of chronic diseases among the Korean population aged 40-69 yrs. Baseline data were collected from 2001 to 2002, and follow-up studies were performed every 2 yrs, with over 7 follow-up studies performed (2015-2016). Three dietary patterns were identified using factor analysis: “vegetable and seafood (men)/soup and stew (women)” pattern, “sweet foods and breads-rice cake” pattern, and “multigrain rice and cooked white rice” pattern. None of the dietary patterns were significantly associated with the risk of CSDs in either men or women. Our follow-up study is meaningful as it investigated whether the dietary patterns of individuals according to sex affects the development of CSDs.

본 연구는 여대생의 체질량지수와 다이어트 인식 및 다이어트 행동에 관해 알아보기 위해 시행된 서술적 조사연구이다. 연구 대상자는 일 지역 여자대학교에 재학 중인 학생 165명으로 자료수집은 2018년 10월 29일부터 11월 9일까지 진행되었다. 수집된 자료의 분석은 SPSS/WIN 21.0 프로그램을 이용하여 기술통계, t 검정, 일원분산분석, 교차분석을 하였다. 전체 다이어트 인식은 3.44점이었고 요인별로는 ‘실행’이 4.00점으로 가장 높게 나타났고, 그 다음으로 ‘정보 및 교육’이 3.58점, ‘필요성’은 3.32점, ‘자가인식’은 2.84점으로 가장 낮게 나타났다. 다이어트 횟수는 ‘3회 미만’이 65명(43.0%)으로 가장 많았으며 방법은 ‘음식조절’이 65명(43.0%), ‘운동’이 62명(41.1%) 순이었다. 일주일간 운동시간은 3시간 미만이 99명(65.6%)으로 가장 많았고 ‘전혀 하지 않는다’가 32명(21.2%)으로 그 다음 순이었다. 다이어트로 인한 피해경험은 22명(14.6%)이 있다고 응답했고, 종류로는 위장병, 생리불순, 탈모 등이었다. BMI에 따른 다이어트 인식 전체 점수는 저체중군이 정상체중 및 과체중군보다 점수가 낮게 나타났다(p<.001). 하부 요인별로 보면 다이어트 ‘실행’은 저체중군이 정상체중 및 과체중군보다 점수가 낮게 나타났고(p<.05), 다이어트 ‘정보 및 교육’은 과체중군의 점수가 가장 높았고, 그 다음이 정상체중군, 저체중군 순이었다(p<.001). 다이어트 ‘필요성’과 ‘자가인식’은 저체중군이 정상체중 및 과체중군보다 점수가 낮게 나타났다(p<.001). 다이어트 인식에 따른 다이어트 행동은 다이어트 횟수와 방법에서 차이가 있었다(p<.001). 본 연구 결과를 토대로 여대생의 올바른 다이어트 인식 형성과 건강한 생활유지를 위한 관심과 교육이 필요하다고 사료된다.

This study examined the eating habits and preferences of foods according to the age of children with autism spectrum disorders and identified the nutritional needs of parents to support their healthy eating habits and provide basic data for the development of educational programs. A survey of 100 parents of children with autism spectrum disorders was conducted on their children’s snack intake, food preferences, and parents’ nutrition education needs. As a result, there were four times more boys than girls, and the body mass index differed according to age (p<0.001). Most children ate snacks more than once a day, and parents found that they wanted to develop nutritious snacks that could replace high-protein, low-calorie meals with the minimal use of additives. For the food preference, there was a significant difference in grains and starches, vegetables/seafood and fruits, milk and dairy products (p<0.05), fats and sugars, and Korean fermented pastes (p<0.01) between the two age groups. Regarding whether nutrition education was required, many parents had a high demand for nutrition education (4.24±0.70), and the intention to participate was 3.62±1.09. The most important content to be dealt with in parent education was ‘Inducing a change in bad eating habits and behaviors’, which was the highest (63%), and mostly face-to-face education was preferred. In conclusion, young children require diet education, and older children need to focus on weight control and obesity.

Tartary buckwheat has established itself as a functional food source because of its basic nutrition and phenolic compound contents, such as dietary fiber (DF) and rutin (RU). However, little information has been obtained concerning the comparative effects of DF and RU on the in vitro and in vivo glucose responses of tartary buckwheat flour. Moreover, the relationship between the flour’s in vitro starch digestibility and its components’ blood glucose response is not well-known. This study found that DF and RU reduced rapidly digestible starch (RDS) by 37.32→33.88% and 41.71→30.28%, whereas they increased resistant starch (RS) by 30.47→31.46% and 28.41→36.78%, respectively. Furthermore, RU had a lower glycemic index (GI) compared to DF. The regression equation for the in vitro and in vivo data from RU exhibited positive correlation (R 2 = 0.99); however, DF did not display positive correlation, which indicates that the in vitro and in vivo GI mechanisms by DF and RU are different.

This study was a qualitative investigation into hemodialysis patients' dietary practices. The purpose of this study was to explore the obstacles and requirements to maintain a recommended diet therapy in hemodialysis patients. Five patients undergoing hemodialysis in the renal chamber of the general hospital were interviewed individually. The interviews were based on an interview guide and analyzed by Giorgi’s method of analysis. As a result of this study, five elemental factors and 12 subelemental factors were derived. Derived elements were “difficulty in dietary guidelines”, “recognizing necessity of diet therapy”, “awareness of importance of diet”, “difficulty practicing diet therapy”, and “looking for ways to practice diet therapy”. Patients not only felt difficulties in practicing dietary guidelines but also recognized the need and importance of diet therapy. Patients seemed to have difficulty practicing meal therapy and eating with their families or others. They were also stressed by the limited selection of dietary components and rapid dietary changes before and after dialysis. However, patients showed a willingness to implement dietary management to improve their quality of life and to practice dietary therapy. In order to improve the practice of dietary management in hemodialysis patients, nutritional education should be focused on long-term dietary habits through continuous education and monitoring, not just one-off education. Moreover, patients should be educated that adherence to dietary control may be less burdensome on their families.

This study was conducted to compare differences in dietary habits and snack consumption behaviors according to level of job stress among 20- to 30-year-old office workers. Subjects were 205 office workers working in companies located in Seoul and the metropolitan area. Self-administered questionnaires written by the subjects were statistically analyzed by the SPSS 20.0 program. Subjects were classified into a high-risk job stress group (n=102, High-RSG) or low-risk job stress group (n=103, Low-RSG) by level of job stress. For dietary habits, the duration of meal time before suffering from job stress in High-RSG was significantly faster compared to Low-RSG. Appetite after suffering from job stress in High-RSG was significantly higher compared to Low-RSG. For snack consumption behaviors, the reason for snack intake was ‘job stress’ for 42.2% in High-RSG and ‘hunger’ for 31.1% in Low-RSG (p<0.05). Energy intake in the form of chocolates, castellacakesmuffins, and flavored milk during working hours was significantly higher in High-RSG compared to Low-RSG (p<0.05). Therefore, this study suggests that dietary guidelines to ameliorate job stress should be developed in order to manage and improve dietary habits caused by suffering from job stress among young office workers at companies.

This study aimed to evaluate dietary behaviors and food allergy status of preschool children in Gwangsan-gu, Gwangju Metropolitan city. The survey included 592 preschool children aged 1-5 years old in 31 childcare facilities. General characteristics, feeding type, complementary feeding, food allergy, dietary behaviors based on the NQ-P questionnaire, and dietary habits of their family were considered. Exclusively breast-fed children was 32.2% of the subjects and the breast feeding duration was 6.5 months. Subjects who had complementary feeding within 6 months was 77.2% and starting time of complementary feeding was 6.1 months. Fifteen percent of the subjects had food allergies and foods that induced allergy were instant foods, eggs, milk and dairy products, nuts, seafood. Food allergy was not related to breast feeding nor complementary feeding. The NQ-P score and its 3 factors including ‘balance’, ‘moderation’, and ‘environment’ were 59.9, 61.1, 56.0, 62.6, respectively. There were positive relations between children’s dietary behaviors and family dietary habits such as breakfast eating frequency and meal regularity. As age of children increased, instant food intake increased and breakfast eating frequency decreased. Proper nutrition education is needed to children, their parents, and their care givers at childcare facilities to improve children’s dietary behavior and health.

This study analyzed the dietary behaviors and adaptation for Korean foods among Central Asian workers(Mongolia, Kazakhstan, Uzbekistan, Kyrgyzstan) living in South Korea to provide basic and fundamental data that allows Central Asian workers to have desirable eating habits while living in South Korea. Questionnaires were completed by 186 Central Asian workers living in South Korea. From this study, we found that 56.8% of respondents ate three meals a day, and 27.2% of respondents ate two meals a day. 29.7% of respondents had no snacks. For adapting Korean food, Mongolia, Uzbekistan, Kyrgyzstan workers had difficulties adapting spicy and salty flavors and unpleasant smell while Kazakhstan workers had difficulties due to sweet flavors and spicy and salty flavors. Men adapted better than women to adapt Korean food. Women respondents ate Korean food more often than men. And the Uzbekistan ratio of eating homeland food daily was the highest. By providing understanding of dietary patterns of Central Asian workers, these results can be used as the basic and fundamental data for their Korean food adaptation.

This study examined the difference of dietary intake behavior between groups of adults aged >20 years with or without dyslipidemia, and comparing the various types of dyslipidemia, based on the Seventh (2016) KNHANES. Men showed higher rate for triglyceridemia and LDL-cholesterolemia than women and subjects in the age group 50-59 years exhibited the highest incidence of triglyceridemia, total cholesterolemia and HDL-cholesterolemia. The ratio of obese people was higher in most types of dyslipidemias. The top five foods in each group of cereal & grain, meat, vegetable, and fruit were selected for analysis, based on the food frequency. The dyslipidemia group showed higher intake frequencies for mixed grains, cabbage kimchi and leafy vegetable than the no-dyslipidemia group, and the group with high blood total cholesterol for mixed grains, apple, and cutlassfish-croaker. Group with high blood triglyceride showed higher intake frequencies of rice and mackerel-mackerel pike than the other groups of high blood triglyceride. No food showed significant difference in the frequencies between groups of LDL-cholesterol. Group with high blood HDL-cholesterol showed higher intake frequency of bibim-fried rice, deep fried chicken, stir fried chicken, apple, tangerine, banana and butter-margarine. These results indicate that people with high levels of blood total cholesterol are more concerned with food having health benefits than those with abnormal levels of other blood lipid. More information on dietary benefits need to be provided to patients having high levels of triglyceride, LDL-cholesterol and HDL-cholesterol.

This study examined the dietary behaviors and dietary quality of high school students according to the number of times they skipped breakfast. A total of 474 high school students (225 boys and 249 girls) residing in Incheon participated in this survey. The subjects were divided into the three groups according to the frequency of eating breakfast; Regualr (eating breakfast everyday, n=226), Irregualar (eating breakfast 1~6 times/week, n=143, and Skipping (skipping breakfast everyday, n=105). The dietary quality was assessed using a nutrient quotient for adolescents (NQ-A). A higher monthly allowance and a higher rate of working mothers were significantly associated with a higher frequency of skipping breakfast. A higher intake frequency of processed beverages, and street food was significantly associated with a higher frequency of skipping breakfast. Students who had a higher rate of breakfast skipping had significantly lower intake frequency of fruits, white milk, bean and bean products, and fish. The high frequency of skipping breakfast among high school students was associated with lower dietary quality, as illustrated by the low total NQ-A score and sub group score including balance, environment, and practice. This information can inform efforts to provide nutrition education program to promote breakfast consumption and guidelines to students who skipped breakfast frequently.

This study examined the nutritional status and dietary behaviors of university students in Gangwon-do as well as the effects of dietary education on them. Forty college students were recruited, and their dietary lifestyle was examined using an Adult NQ questionnaire before and after dietary education. The questionnaire items were grouped into four categories: balance, diversity, moderation, and dietary behavior. The mean NQ score out of 100 was 48.00. Among the three grades of the NQ grade criteria, most subjects (50%) were in the lowest grade, which was poor. The mean scores of the NQ factors were highest for moderation (68.76%), followed in order by diversity (50.81%), dietary behavior (45.66%), and balance (21.01%). Compared to the criterion value, moderation was only good, and balance was the worst. These results suggest that the nutritional status of the subjects is poor. On the other hand, there was a significant change in the areas of the NQ score (53.7), balance (29.22) and dietary behavior (56.77) after dietary education. Nevertheless, the ‘balance’ area remained lower than the average, highlighting the need for education on food intake to enable diverse food intake.

This study investigated the general information, unbalanced diet, and dietary habits of 86 children in Daegu. The research was undertaken to analyze the current state of diet and dietary habits of children, and to provide basic data for nutrition education. The results reveal that younger children have a more unbalanced diet. Children dislike side-dishes the most. Furthermore, due to the longer time taken to consume food, parents persuade children to eat quickly. Children were also determined to have a high intake of foods and drinks containing sugar; beverages containing sugar are consumed 1-2 times a week by 5-year-olds, and once daily by 6- and 7-year-olds. The results of this study can be applied to provide basic data for nutritional education, and assist in the development of dietary programs for young children.

The Ministry of Agriculture, Food and Rural Affairs has conducted the Dietary Education Projects at Childcare Centers since 2015. This study provides preliminary data for early childhood dietary education programs, by evaluating the outcomes of the projects. This survey enrolled 212 participants whose children had participated in the projects, and 142 non-participants. Comparing the perception of importance towards each educational program of the projects, dietary education program gained significantly higher importance than other subjects included, and was significantly higher in the participants than in non-participants. In the preference for food group survey for children, vegetable and seaweed preferences were higher among participants than non-participants, indicating that participation in the dietary education projects contribute towards increase in preferences for vegetables and seaweed, which children generally dislike. No significant differences were observed in children’s dietary habits between participant and non-participant groups, thereby suggesting that the education projects were insufficient for inducing dietary habit changes. In order to accomplish effective improvement of dietary habits, the education projects need further improvements to achieve systematic and long-term plans.

The purpose of this study was to develop a dietary education program, and to evaluate the effectiveness of the education program for children from low-income families. A total of 242 children (122 education groups and 120 control groups) were run six times a dietary education program from April to December 2018, and a questionnaire was administered before and after the education to evaluate effectiveness. Elementary school students were the most prevalent in the education and the control group. In the education group, the body height and weigh were 137.27 cm and 33.69 kg, respectively, and in the control group the body height and weight were 143.48 cm and 40.64 kg, respectively. The education group showed positive change in dietary self-efficacy and dietary knowledge compared to the control group. In particular, ‘I can have meals regularly’ (Education Group: 4.00 points from 3.71 points) and 'I can choose fruits instead of cookies candies as snacks (Education Group: 4.01 points from 3.70 points) The score increased after participation in the program. In the change of nutritional and hygiene knowledge of children, the education group scored 3.63 of 10 points before education, but the score significantly increased to 5.70 points after education(p<0.001).

The purpose of this study was to investigate the factors related to milk consumption in university students. A questionnaire, comprised of general questions and factors related to milk consumption, was administered to 269 male and female university students (134 males, 135 females). The results show that the proportion of males reporting that they drink milk because “for good nutrition” was higher than that of females (p=0.0200). Additionally, males initiated more effort to drink milk than females (p=0.0192). Analysis of the groups classified according to milk consumption shows that the proportion of respondents exercising regularly was significantly high in the milk consumption group (p=0.0199). The proportion of respondents often consuming carbonated drinks as snacks was significantly low in the milk consumption group (p=0.0219). Whereas, the proportion of respondents consuming fruits as their main snack was significantly higher in the milk consumption group than in the non-milk consumption group (p=0.0063). Also, the milk consumption group shows significantly higher awareness of the importance of milk than the non-milk consumption group (p<0.0001). These results can be used as a valid foundation to provide university students with nutritional education relative to milk consumption and its associated benefits in the future.

This study aim to evaluate dietary quality and nutritional status according to the consumption of health functional food using Nutrition Quotient for Korean elderly (NQ-E) for 288 elderly people attending senior welfare centers in Gyeonggi-do. The questionnaire consisted of items about general information, health functional food, and Nutrition Quotient for Korean elderly (NQ-E). Chi-squared test, Fisher's exact tests, and Analysis of Covariance (ANCOVA) were performed using the SAS program ver. 9.4. Among the male and female subjects, the female subjects consumed more health functional food. The results of the dietary quality and nutritional status difference according to the intake of health functional food showed significant differences only in the areas of variety and abstinence among nutrition quotient factors for men, while no significant differences were observed in any of the nutrition quotient factors for women. In conclusion, focused-nutrition education program and useful guideline is needed for promoting adequate consumption of health functional foods in elderly.

The objective of this study was to analyze proximate composition, dietary fiber, mineral content, fatty acid composition in Cheonggak (Codium fragile) in order to encourage the consumption of Cheonggak. The proximate composition of Cheonggak was found to be 5.51% moisture, 24.09% crude ash, 15.79% crude protein, 2.47% crude lipid and 45.31% dietary fiber. The major mineral content of Cheonggak was Na 8,950 mg/100 g, Mg 1,252 mg/100 g, Ca 807 mg/100 g, K 457 mg/100 g, and trace mineral content was Fe 26 mg/100 g, Mn 8 mg/100 g, Zn 0.4 mg/100 g. Palmitic acid 36.86% and α-linolenic acid 20.14% were the most contained fatty acids in Cheonggak. The ratio of saturated fatty acids to unsaturated fatty acids was 85.49% while ω-6 fatty acids to ω-3 fatty acids were 59.10%. Based on the proximate composition, dietary fiber, mineral content, and fatty acid composition, Cheonggak was judged to be a major source of dietary fiber and Mg and Ca, and it was deemed to be helpful in promoting health, including the prevention of hyperlipidemia. Cheonggak contained valuable nutrients similar to seaweed, which is produced and consumed the most in Korea. Thus, it is necessary to include Cheonggak in the food items.
