This study was conducted to investigate the anthropometric data, serum profiles, food intakes frequency, and nutrient intakes of women aged 30-49 years. The subjects were divided into two groups: drinking group and non-drinking group. For the study, we obtained data for analysis from the combined 2008-2015 Korean National Health and Nutrition Examination Survey (KNHANES). Height and weight were 159.2 cm and 58.1 kg in the drinking group as well as 158.1 cm and 57.7 kg in the non-drinking group, respectively. Obesity percentage in the two groups were 22.5% and 24.8%, respectively. HDL-cholesterol (P<0.001) and Vitamin D (P=0.0248) levels in the drinking group were significantly higher than those of the non-drinking group. In the drinking group, rates of hypertension, myocardial infarction, and diabetes were significantly lower than those of the non-drinking group. Food and nutrient intakes, including energy, water, protein, fat, retinol, thiamin, riboflavin, and niacin, in the drinking group were significantly higher than those of the non-drinking group. In the two groups, energy, water, fiber, calcium, and potassium intakes were low while Na intakes were extremely high considering KDRIs (Dietary Reference Intakes for Koreans). The mean adequacy ratio (MAR) in the two groups was not significant.

This study was an investigation of nutrient intake and food habit of college students in Taegu. A total of 200 apparently healthy college students living in Taegu were selected for the study. The 24-hour recall were obtained from subjects. The following anthropometric measurements were made on all participants: weight, height, waist and hip circumferences, and bioimpedence. Dietary habits and energy expenditure were examined through questionnaires. Among the subjects 8.3% were obese and 17.7% were underweight in male and 38.8%, respectively. The average intake of nutrients and energy were below the RDA in male(except protein, vitamin C and phosphate) and female(except vitamin C and phosphate), whereas phosphorus intakes well exceed the RDAs for both groups. Lowest mean intake as percentile of RDA were calcium and riboflavin in male, and calcium and iron in female. The mean adequacy ratio(MAR), an index of overall dietary quality was 0.735 for males and 0.730 for females. The index of nutritional quality (INQ) were under 1.0 for vitamin A(0.91), B2(0.628), Ca(0.074), Fe(0.845) in male students and vitamin B2(0.752), Ca(0.649), Fe(0.594) in female students. The alcohol consumption level was negatively correlated (p<.05)with thiamin, ascorbic acid, carbohydrate, and energy consumption in male students. Also the alcohol consumption was negatively correlated (p<.05) with milk consumption in male students. Thus, unfavorable nutritional patterns of alcohol drinkers put them at double jeopardy regarding micronutrient intake and bone health. In conclusion, this study indicates that nutrient intake in the college student in Taegu is considerably lower than RDA. Another important finding of this study is that an unacceptable calcium and iron status was prevalent in a high percentage of subjects in the college student.

The study classified 83 obese adults by constitution and had them follow a strict diet according to their constitution in order to see if the Yin-Yang method would be effective on the metabolic syndrome, which is one of the main causes of death in Korea. Overall, the application of both Yin and Yang methods improved the following factors: weight, body fat percentage, systolic blood pressure, diastolic pressure, neutral fats and total cholesterol. In particular, the Yin constitution group of men showed more improvements than the Yang constitution group. Furthermore, waist circumference and the prevalence rate of systolic blood pressure, diastolic pressure, total cholesterol and metabolic syndrome were decreased noticeably. Total energy intake was increased in both men and women after the constitutional diet, along with the increase of nutrient intake, such as dietary fiber, vitamins and minerals, among others. Among various nutrients, vitamin A, vitamin C, thiamine, vitamin B6, folic acid, calcium, phosphorus, potassium, magnesium and iron intake were increased noticeably after the constitutional diet. In addition, subjects' intake of all nutrients, except for magnesium, satisfied the nutrition intake standards. Further, the nutrients adequacy ratio (NAR) and the mean adequacy ratio (MAR) improved for both men and women. The intake of potatoes, starch, greens and mushrooms increased noticeably, whereas the intake of meat, dairy, drinks and alcohol decreased after the constitutional diet. For the Yin constitution, the intake of Yin foods noticeably decreased, where as the intake of Yang foods decreased for the Yang constitution. In conclusion, the constitutional diet effectively improves the metabolic syndrome. Among many nutrients, the intake of dietary fiber, vitamins A, C and E, potassium and magnesium is positively associated with the improvement of metabolic syndrome biomarkers.

This study was conducted to assess the dietary intake of college students in Gyeonggi-do. The dietary survey data were obtained by a semi-quantitative food frequency questionnaire given to 103 students, 56 males and 47 females. The average age the of subjects was 22.5 years old for the male students and 20.9 years old for the female students. Among the subjects, 38 males and 26 females' height, weight and percentage of body fat were measured using Inbody 3.0. The average height, weight, Body Mass Index(BMI) and percentage of body fat of the subjects was 173.1cm, 68.6 kg, 22.9 and 18.9% for males and 162.5 cm, 54.1 kg, 20.5 and 28.1% for females, respectively. The mean daily intake of energy was 2,343.0 kcal for males and 2,062.0 kcal for females. The average intake of protein, carbohydrates, Vitamin B1 in the male students were significantly higher than those of the female students(p<0.05). The average of Nutrient Adequacy Ratio(NAR) was ranged from 0.60(folate) to 0.99(phosphorus). NAR of Vitamin A and calcium was 0.71 and 0.75, respectively. The average of Mean Adequacy Ratio(MAR) was 0.85. The intake of rice and oriental cereals(sum of the parched cereal powder, ramen, noodles, Chajangmyon, buckwheat vermicelli, buckwheat noodles, dumplings and rice cakes) in the males was significantly higher than those of the females. The intake of snacks in the females was significantly higher than that of the males. Appropriate nutritional education for an optimal intake of nutrients may help to improve the quality of diet in college students.

To assess the food intake and diet quality of Koreans living in rural areas with discriminative environment, this dietary survey was conducted with 553 subjects living in five different rural areas using a one-day, 24-hour recall method. The average weight of total food intake was 1066g, with vegetable and animal food comprising 83.75 and 16.3% of total food intake, respectively. The average daily food intakes of residents in the five areas were 985g, 1005g, 1028g, 1318g, and 964g, and were significantly different(p<0.001). Residents of Ulju consumed the largest amount of food, 1318g. The total number of food items consumed was 336. The foods consumed in largest amounts were rice(223g), Korean cabbage-Kimch'i(111g), and soybean curd(41g). The foods consumed most frequently were rice, Korean cabbage-Kimchi, green onion and garlic. When investigating the consumption pattern of the major five food groups, only 5% of subjects consumed all five groups. The groups most frequently missing were dairy products and fruits. The average number of foods consumed per day was 16.8, but differed significantly by area(p<0.001). The number of major food groups (DDS, dietary diversity score) and that of food items(DVS, dietary variety score) correlated positively with NAR (nutrient adequacy ratio) and MAR (mean adequacy ratio). People with a DDS of above 4 or DVS of above 20 met two-thirds of the recommended dietary allowance for most nutrients. When assessing the dietary quality of subjects using DDS and DVS, many people appeared not to have a desirable food intake. dietary guidelines should be made considering the nutritional characteristics of different areas to improve the health of people living in those areas.

The purpose of this study was to evaluate the dietary habit, nutritional condition and quality of everyday meal for college students. The number of the subjects was 102 and they were divided into three groups by their residing types; students living with their parents (n=34), students living in dormitory (n=34) and students living independently off the campus (n=34) Questionnaire, 24hour dietary recall for food intakes, and body composition analysis were used. SPSS program was used for the statistics. In general health matter, the average age for each group of students was $21.2kg/m^2$, $20.9kg/m^2$, and $21.9kg/m^2$ respectively. And heights, weights, muscle mass, body fats and BMI were not significantly different between groups. Results on dietary habit showed that students living with their parents had better meal pattern and regularity for breakfast than other groups. Also, for dietary evaluation, students living with their parents showed better extent of intake of milk than other groups. Evaluation on nutrients intake showed that amount of calcium, vitamin $B_2$, folic acid intake in student living independently off the campus were lower than those of the other groups(P<0.05). And MAR(Mean Adequacy Ratio) was not significantly different between groups, however INQ(Index of Nutritional Quality) and NAR(Nutrient Adequacy Ratio) of calcium were lower in off the campus group than other two groups. In conclusion, students living independently had worse eating habits and showed lower intake of calcium than those living with their parents or living in a dormitory. Therefore nutritional education for improving well-balanced dietary habits and optimal intake of nutrients are required especially for students living independently off the campus.

The purpose of this study was to investigate the effects of nutrition education on nutrition knowledge, dietary attitude and dietary intake of Chinese college students in Korea. The subjects were 64 Chinese college students in Korea (educated group, 32 students vs. non-educated group, 32 students). Educated group was lessoned as group and/or individual. Nutrition education program consisted of four lessons (40min/lesson), '6 major nutrients & function (group lesson)', '6 food group and sources (group lesson)', 'personalized daily needed energy and food exchange units using Food Exchange System (individual lesson)', and 'smart choice of snacks and eating-out foods (group lesson)'. We examined the differences between educated group and non-educated group in nutrition knowledge, dietary attitudes and nutrients intake. After education, there were positive improvements on nutrition knowledge: 'function and foods of 6 nutrients', on dietary attitudes: 'type of breakfast' in educated group. In the evaluation of nutrient intakes according to Dietary Reference Intakes for Korean (KDRI), there were positive improvements on intake levels of riboflavin, fiber, vitamin B6, vitamin C, folate, Ca and K in the educated group. In the index of nutrition quality (INQ), nutrition adequacy ratio (NAR) and mean nutrition adequacy ratio (MAR) were significantly increased in the educated group. In conclusion, it is possible to improve nutrition knowledge, dietary attitude and dietary intake of Chinese college students in Korea through the nutrition education focused on personalized daily needed energy and food exchange units.

The nutritional balance of the menu plans prepared according to the target pattern was examined. Total of 81 home economics teachers throughout the nation and 161 3rd-grade middle-school girls in Chungnam area participated. The data was collected by questionnaire and analyzed by using SPSS WIN 12.0. Although both teacher and student groups had fairly good knowledge on preparing menu plans related concepts, they rarely make use any menu planning currently. More than 85% of menu plans investigated exceeded their energy goal in the target pattern. The energy contribution ratios of carbohydrate: protein: fat were 56.1%: 17.4%: 26.5% in teachers' menu plan and 55.1%: 17.2%: 27.7% in students' menu plan. The NAR of the protein, phosphorous, iron, zinc, vitamin A and C, thiamin, riboflavin, niacin, B6 was 1 or near 1. But in case of calcium, 56.5% of the menu plan prepared by the students was less than 1, and in case of folate 75.3% of teachers', and 85.1% of students' were less than NAR 1. The MAR of the 12 nutrients examined were 0.98, 0.97, and the DVS were 51, 49 for menu plan prepared by teachers and students, respectively.

This study was conducted to examine the status of food consumption and nutrition intake of young adults according to food security using data from the Korea National Health and Nutrition Examination Survey (KNHANES) (2008~2018). A total of 10,655 young adults aged 19~34 years participated in the study. The subjects in the moderately/severely food insecure group consumed less fruits, vegetables, meat, nuts and seeds than those in food secure/mildly food insecure group after adjusting for confounding factors. The moderately/severely food insecure group significantly decreased mean adequacy ratio (MAR) and nutrient adequacy ratio (NAR) for protein, vitamin A, riboflavin, niacin, vitamin C, calcium, phosphorus and iron compared to the food secure/ mildly food insecure group. The percentages of the participants consuming a daily diet with carbohydrate, protein, vitamin A, thiamin, riboflavin, niacin, vitamin C, phosphorus and iron less than the estimated average requirement (EAR) increased in the moderately/severely food insecure group compared with the food secure group. This study suggested that the nutrition intake of young adults was related to food security status. These findings can be used as basic data for developing nutritional policies for young adults.

BACKGROUND/OBJECTIVES: This study analyzed the quality of lunches provided in senior leisure service (SLS) facilities and compared institutional foodservice (IF) and non-institutional foodservice (non-IF). SUBJECTS/METHODS: Data of 390 adults aged 65 years or older who ate lunches in SLS facilities were analyzed using the information from the 2013-2017 Korea National Health and Nutrition Examination Survey. The participants were classified into IF (n = 129) and non-IF (n = 261) groups according to meal type provided. The intake of major food groups, energy and nutrients, and nutrient adequacy ratio (NAR) and mean adequacy ratio (MAR) were analyzed. The diversity of meals was evaluated by food group patterns, dietary diversity score (DDS) and dietary variety score (DVS). Energy intake was adjusted in model 1, while energy and sex were adjusted in model 2. All confounding variables were adjusted in model 3. RESULTS: The intake of seafoods (P < 0.001 in models 1, 2, and 3), seaweeds (P < 0.01 in models 1 and 2), and dairy products (P < 0.05 in models 1, 2, and 3) was significantly higher in the IF group. No significant difference existed in energy intake; however, the intake of all nutrients except carbohydrate and vitamin C was significantly higher in the IF group. NAR of all nutrients, excluding vitamin C, was higher in the IF group, and MAR was also higher in the IF group (P < 0.001 in models 1, 2, and 3). The IF group had significantly higher DDS and DVS than the non-IF group (P < 0.001). CONCLUSIONS: The lunches provided in SLS facilities were better in terms of quantity and quality when provided through IF than through non-IF. More systematic foodservice programs should be implemented in SLS facilities, especially in facilities wherein users prepare their own meals.
