The most critical point in the assessment of adherence to dietary guidelines is the development of a practical definition for adherence, such as a dietary pattern score. The purpose of this study was to develop the Korean Diet Score (KDS) based on the Korean Food Balance Wheel and to examine the association of KDS with various lifestyle characteristics and biochemical factors. The dietary data of 5,320 subjects from the 4th Korean National Health and Nutritional Examination Survey were used for the final analysis. The food guide was composed of six food group categories; 'grain dishes', 'fish and meat dishes', 'vegetable dishes', 'fruits', 'milk' and 'oils and sugars'. Based on the recommended serving numbers for each group, the scores measuring adherence to this food guide were calculated from the dietary information from the 24-hour dietary recall questionnaire, and then its correlation with various characteristics was assessed. KDS was significantly associated with several clinical, lifestyle and socioeconomic factors as well as diagnosed disease history. The higher quintile group of KDS showed a significantly lower level in fasting blood glucose, systolic blood pressure, triglycerides, current smoking and drinking as well as higher leisure time activity, house income and education. Furthermore, the KDS quintile group of women was inversely associated with hypertension, osteoporosis and diabetes. A higher KDS quintile was characterized with a higher intake of several critical nutrients, such as Ca, Fe and vitamins as well as a desirable nutrition balance such as the ratio of macronutrients. Our results demonstrate that KDS is a beneficial tool in assessing the adherence to a healthy diet based on the Korean dietary guidelines. We suggest that KDS could be a useful indicator for evaluating the dietary balance of the Korean population.

The study aims to examine college students' practice characteristics related to diet and to identify factors determining their diet practice. The subjects were college students (N=387) in Youngnam region; a questionnaire survey was conducted in May, 2007. The data were analyzed by SPSS Windows. The results are as follows: first, the ratio of female students going on a diet is higher than that of male students. Second, according to the BMI, female students more regard themselves as being overweight than male students do, although they are underweight or normal weight. Third, in the interest in diet, almost half the students think of themselves as being "somewhat" or "much" concerned about diet. Fourth, the binary logistic regression analysis shows that the significant factors affecting female students' diet practice are the variables of "grade", "interest in diet", "body image evaluation in the individuals", "information/education requirement on dietary guidelines", and "necessity to go on a diet". On the other hand, the significant variables affecting male students' diet practice are the variables of "to take diet- or health-related courses", "interest in diet", "diet knowledge", and "diet practice".

BACKGROUND/OBJECTIVES: The objective of this study was to describe the development process of the Korean Healthy Eating Index (KHEI) based on the Korea National Health and Nutrition Examination Survey (KNHANES). SUBJECTS/METHODS: The components of KHEI were selected based on Dietary Guidelines for Koreans, domestic and overseas dietary quality indices, and results of the analysis of association with chronic diseases. The standards for scoring of KHEI were selected based on the 2015 Dietary Reference Intakes for Koreans (KDRI). The KHEI scores of Korean adults were calculated using a 1-day 24-h recall data in the 2013-2015 KNHANES. RESULTS: The KHEI included eight adequacy components evaluating the proper intake of recommended foods such as fruit, vegetable, and milk and three moderation components evaluating the consumption of food that limit intake such as sodium and saturated fatty acid. In addition, three balance components assessing the balance of energy intake were included. The KHEI score was defined to range from the minimum of 0 point to the maximum of 100 points. Among Korean adults, the total KHEI score was 63.2 out of 100. Gender and age differences were found in the average of total KHEI scores. Women showed higher score than men (61.7 in men and 64.7 in women, respectively). By age group, 20s and 30s showed the lowest scores with 57.4 and 61.1 respectively, and the scores increased with age by peaking at 67.8 in ages 60-69 and slowed down again in ages 70 or over. CONCLUSIONS: The KHEI can be useful for establishing and assessing national nutritional policies and in epidemiological studies to assess the relationship between overall dietary quality and chronic diseases. KHEI will need to be continuously updated to reflect changes in dietary guidelines and the KDRI.

Purpose: The aim of the study was to determine the effects of a community based participatory program in obese middle-aged women. Methods: One-group pretest-posttest design was used. The subjects were 35 middle-aged women. Data were collected at public health centers in Chungcheongnam-Do from March to May, 2013. To evaluate the effect of the program, physiological indexes(body mass index, skeletal muscle mass, body fat mass, visceral fat area) and health behavior indexes(dietary practice guidelines score, moderate physical activity, drinking frequency) were measured. Analysis was performed using a Wilcoxon Signed Rank Test. Results: After the program, physiological indexes (BMI, BFM, SMM, VFA) and health behavior indexes (dietary guidelines scores, frequency of physical activity, drinking frequency) were significantly improved. Conclusion: The community based participatory obesity program by public health centers is considered to be effective. Therefore, greater effort is needed for better participatory program development of several health promoting fields, and more research is needed in order to examine a continuous effect.

BACKGROUND/OBJECTIVES: Over the past few decades, Malaysia has been experiencing an increased prevalence of overweight and obesity that threatens the health of Malaysians. Poor dietary intake is one of the major contributors to the development of obesity and many non-communicable diseases. The dietary intakes of adults in Malaysia were assessed to determine the association between the dietary intake variables and the body mass index (BMI) and waist circumference (WC) measurements. This study examined whether the dietary intake achieved the recommended nutritional guidelines and compared the intakes between both sexes. SUBJECTS/METHODS: The height, weight, and WC of four-hundred-and-ninety adults (n = 490) in Malaysia were measured using standard procedures. The three-day 24-hour dietary recalls were conducted on 422 out of the 490 adults and their dietary intakes were evaluated in detail. The selected dietary intake variables were used to determine the associations with the obesity indicators. RESULTS: Among the participants, 52.8% were overweight or obese. After data analysis, the mean energy intake was 1,550 kcal/day, in which male participants had a significantly higher energy and macronutrients intake than females. Protein consumption and its percentage of energy contribution exceeded the recommended range. The consumption of fruits, vegetables, and milk and milk products were lower than the recommended number of servings for a healthy diet. The male participants consumed significantly more servings of carbohydrate-based foods, meat, and fats, oils, and sweets than females. Among the selected dietary intake variables, only the carbohydrate intake was negatively associated with the BMI (Estimate b = -0.008) and WC measurements (Estimate b = -0.019) after adjusting for covariates. CONCLUSIONS: This study evaluated the dietary intakes of a sample of Malaysian adults and its association with the obesity indicators. The results highlight the need for improvements and modifications of the dietary intake of Malaysians to reduce the overweight and obesity rates.

Sustainable meal management at home will be affected by the lifestyle of the housewife. This study examined the lifestyle of middle aged women and identified their practice levels of sustainable meal management at home. A total of 438 women, aged 35 to 59, managing the family's dietary life at home and living in Seoul, Gyeonggi Province, Daejeon, and Chonnan area participated in the survey. The middle aged women showed a higher performance level of hygiene-oriented (4.15) and health-oriented dietary life (3.59), but a less convenience-oriented dietary life (2.57). Based on their lifestyle, 3 clusters were extracted: Low-interest dietary life meal manager, health and quality pursuit meal manager, and convenience and eating-out pursuit active meal manager. Among them, the cluster of health and quality pursuit meal manager showed the highest sustainable practices in 7 dimensions of sustainable practices in the home except for the saving practices (p<0.001). The criteria suggested from the study can be applicable to the guidelines of sustainable meal management at home. The study can also be helpful for educators to identify the education themes for improving housewife's sustainable meal practices, having different lifestyle and sustainable meal practices.

Objectives: This study was conducted to investigate the nutritional status and dietary behavior of Korean and Chinese elementary school children using Nutritional Quotient (NQ). Methods: The survey was conducted by distributing questionnaires to the parents of the child, after selecting four elementary schools located in Pusan city of Korea and three elementary schools located in Luoyang city, Henan Province of China, from Grade 1 to Grade 6 in each school. Results: The NQ scores of Korean children and Chinese children were 64.99 and 66.57, respectively, which did not show a statistically significant difference. Korean children significantly showed higher diversity score (p<0.001) than Chinese, but Chinese children significantly showed higher moderation (p < 0.001), regularity (p < 0.001) and practice score (p < 0.01) than Korean. NQ grades showed a statistically significant difference. According to food security of the household, NQ scores of the Chinese children of secure household were significantly higher than those of food insecurity household (p < 0.01). In particular, it showed a significant difference in the practice (p < 0.001), moderation (p < 0.05) and regularity score (p < 0.05). Korean children's NQ score showed a significant correlation with the score of following the Dietary Guidelines of parents, but Chinese did not show such a correlation. Conclusions: There were differences in children's dietary behaviors and parents' impact to children's dietary attitude between Korean and Chinese. NQ developed for Korean could be successfully applied to Chinese.

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.

Consumption of a diet consistent with dietary guidelines is believed to have a beneficial effect on the prevention of chronic diseases and the promotion of general health. This study was conducted to explore the relationship between adherence to the Korean Food Guidance System (KFGS), which was based on the 2010 revised KDRIs, and the risk of metabolic abnormalities. Five hundred and ninety-six Korean adults between 30 and 59 years of age were recruited by advertisement to the Bundang Jesaeng General Hospital (BJGH), and those not taking regular medications and without diagnoses of fulminant disease were included. Data were collected on anthropometric measurements, diagnostic parameters for metabolic syndrome (MetS), and 3-day dietary intakes from individuals in the study. The number of servings consumed from each food group was compared to the KFGS recommended servings for each of the 6 food groups. Poor adherence to the recommendations for servings of milk and dairy products (OR: 2.038, 1.128-3.682) was associated with a higher risk of MetS, and poor adherence to the guidelines for fruit consumption (OR: 1.849, 1.027-3.329) was associated with a higher risk for the existence an elevated waist circumference. Conversely, the consumption of meat, fish, eggs, and beans above the recommended number of servings was associated with a lower risk of having an elevated waist circumference (OR: 0.523, 0.288-0.950), and the consumption of vegetables above the recommended number of servings was associated with a reduced risk of having elevated fasting glucose (OR: 0.533, 0.298-0.954). These results suggest that adherence to the KFGS guidelines helps to prevent the development of MetS, but this association needs to be confirmed by prospective studies.

Onto the world-fastest ageing of society, the world-lowest fertility rate prompted a development of various policies and programs for a betterment of the population in Korea. Since the vulnerability of young children of low socio-economic class to malnutrition was clearly shown at the in-depth analysis of the 2001 Korea National Health and Nutrition Examination Survey data, an effort to devise supplemental nutrition care program for pregnant/breastfeeding women, infants and preschool children was initiated. The program was designed to offer nutrition education tailored to fit the needs of the participants and special supplementary foods, using USDA WIC program as a benchmark. Based on the dietary intake of those age groups, target nutrients were selected and their major food sources were searched through nutrient content of foods and dietary pattern analysis. As a result, we developed 6 kinds of food packages using combinations of 11 different food items. The amount of each item in a food package was determined to supplement the intake deficit in target nutrients. Nutrition education in $NutriPlus^+$ aims to improve the nutrition knowledge, attitude, and dietary behaviors of the participants, and is provided through group lessons, individual counseling sessions and home visits. Breastfeeding is promoted with top priority in education for the health of both mother and baby. The eligibility guidelines were set for residency, household income, age, pregnancy/breastfeeding and nutritional risk such as anemia, stunting, underweight, and/or inadequate nutrient intake. Income eligibility was defined as household income less than 200 percent of the Korean poverty guidelines. A pilot study to examine the feasibility of program implementation was run in 3 public health centers in 2005 and expanded to 15 and 20 in the following 2 years. The result of 3-year pilot study will be reported separately along with the ultimate nationwide implementation of the $NutriPlus^+$ in 2008.
