The purpose of this study was to assess several indices of diet quality based on nutrient, food and food group intake of Korean adolescents based on several indices on diet quality according to residence area and body size. Using the data from the 1998 National Health and Nutrition Survey, twenty-four-hour-dietary recalls of a total of 1,110 Korean adolescents aged 13 - 19 years (male 543, female 567) were analyzed for nutrient adequacy ratio (NAR) , index of nutritional quality (INQ) , the number of foods (Dietary Variety Score, DVS) and food group consumed (Dietary Diversity Score, DDS) . In doing that, it was attempted to apply only the minimum amount of solid foods of Kant's without inclusion of liquid foods because of the very limited variety in Korean foods. Based on weight length index, 13.1% of the subjects were categorized as obese, 14.2%, overweight, 44.4%, normal and 28.3%, underweight. Only vitamin B2 intake was higher in the obese group than in the underweight group. There was no meaningful difference in energy, protein and fat intakes according to the grade of the body size. In terms of residence area, intake of fat, niacin, vitamin $B_6$ and folic acid were lower in the rural areas than in the metropolitan city. Only vitamin E intake was higher in the rural areas. Mean value of NARs (MAR) and INQs (mINQ) was also higher in the metropolitan city than in the rural areas, but there was no significant difference of these two values according to body size of the subjects. Mean DVS was 21.02 for total subjects, and has no difference between male and female and between metropolitan city and other medium-small city. But, the rural areas showed the lowest DVS of 19.05. Mean DDS in which five is a maximum score was 3.3 with no significant difference by sex and by residence area in male subjects. However, in female subjects, DDS in the rural areas was the lowest. According to body size of the subjects, there was no meaningful difference in both scores of DVS and DDS. In conclusion, most indices of nutrient intake and food and food group intake were not significantly different by body size of the subjects, while most indices were significantly different by residence areas: higher in the metropolitan city than in the rural area.

The purpose of this study was to compare the quantitative and qualitative assessment of dietary intake between patients with metabolic syndrome (MetS) and healthy subjects and to investigate dietary factors related to MetS. Anthropometric measurements, blood analysis, and dietary intake as assessed by 24-hour recall were conducted in MetS patients (n=15) and healthy subjects (n=25). In order to assess the quantity and quality of dietary intake, daily nutrient intake, nutrient density, nutrient intake to dietary reference intake (DRI), nutrient adequacy ratio (NAR), food intake, dietary diversity score (DDS), and dietary variety score (DVS) were analyzed. The statistical differences between MetS patients and controls were analyzed using the SAS software program. Daily energy intake and food intake were not significantly different between the two groups (2,154.3 kcal vs. 1,872.9 kcal; 1,280.0 g vs. 1,261.6 g). There were also no significant differences in daily nutrient intake, nutrient intake ratio to DRI, NAR, or DVS between the MetS group and the control group. However, daily intake of eggs and milk in MetS patients was significantly lower than in the control group (9.0 g/day vs. 30.3 g/day, p<0.05; 0 g/day vs. 49.7 g/day, p<0.05). These results indicate that low intake of eggs and dairy products may be related to the development of MetS.

The objective of our study was to evaluate the dietary intakes and eating habit for seniors utilizing ten different social welfare centers in Seoul, Korea. The total number of subjects of this study was 543(male: 199, female: 344) of 60 years of age or older. The survey was performed through personal interview questionnaires from May 3rd to June 1st 2006. After assigning subjects to four categories based on family type, single, couple, joint family, and other, these categories were compared with the estimated total nutrient intakes and eating habit. Validity was assessed by comparison with 24-hour dietary recalls and dietary variety score(DVS). The results showed that senior in single family type was far lower than that of couple family type in terms of frequency of meal per day and intake of snacks. Dietary variety score represented that a single female with social security beneficiary showed the lowest variety score compared with other family type. The lunch meal provided by social welfare center turned out to be the most nutritious diet and had significant proportion of daily intakes in essential nutrients such as protein, iron, vitamin A, and vitamin C. Taken together, the family type was a significant factor and the accompaniment is another effector on dietary pattern in the elderly. We strongly suggest that the current lunch program in welfare center should be expanded to breakfast meal, and furthermore the small commodity program is also needed to provide the elderly with meal for social communication.

BACKGROUND/OBJECTIVES: This study investigated gender and age differences in nutrient intake and dietary quality of people eating alone. SUBJECTS/METHODS: From Korean National Health and Nutrition Examination Survey 2013-2016 data, 2,305 adults aged 20 years and older that ate meals alone were included in this study. Their energy and nutrients intakes, as well as their nutrient adequacy ratio (NAR), mean adequacy ratio (MAR), and index of nutritional quality (INQ) were analyzed. Food group consumption pattern, dietary variety score (DVS), dietary diversity score (DDS) were also analyzed. All data were compared among gender and age groups. RESULTS: Men consumed more energy and nutrients than women, except for vitamin C, and the NARs showed similar gender differences. The INQs of 4 nutrients (calcium, vitamin A, vitamin C, and riboflavin) were lower than 1.0 in men, whereas only the calcium INQ was lower than 1.0 in women. Men had a lower DDS (3.6) than women (3.9) (P < 0.001) and had more 'undesirable' food group consumption patterns than women (P < 0.001). The intakes of calcium, vitamin A, and vitamin C were relatively low in the young-aged group (INQs less than 1.0). In the old-aged group, the MAR level was relatively low, and the INQs of calcium, riboflavin, and niacin were below 1.0. The old-aged group consumed more menu items, but their DVS was the lowest. CONCLUSIONS: Compared to women, the dietary quality and food diversity among men were poorer. There were poorer quality and diversity patterns in the young-aged group compared to those of the older groups. An overall low intake of nutrients and the low nutrient density of meals were the main dietary problems among the old-aged group who eat alone. Therefore, men, particularly young- and old-aged, need to be prioritized in nutritional policies directed toward those who eat alone.

The purpose of this study was to compare nutrient intake and diet quality of obese women to those of non-obese women, and to investigate the relationship between diet quality and obesity index in females. We analyzed data from the combined 2007-2009 Korean National Health and Nutrition Examination Survey (KNHANES). In this study, according to their BMI (above $25kg/m^2$), we classified the subjects into the obese group (n = 724) and non-obese control group (n = 2,841). Nutrient adequacy ratio (NAR), the number of foods (Dietary Variety Score, DVS), and food groups consumed (Dietary Diversity Score, DDS) were analyzed by using the data from the 24-recall method. The average energy intake of both the obese and control group were 1634.94 kcal and 1,707.81 kcal, respectively (p = 0.0199). The obese group consumed significantly lower quantities of calcium per 1,000 kcal compared to the control group (p = 0.0261). With regards to diet quality, calcium NAR in the obese group was significantly lower than that of the control group (p = 0.0158). MAR values for the obese and the control group was 0.79 and 0.80, respectively and revealed no statistical difference. The obese group showed a significantly lower consumption of milk compared to the control group (p = 0.0162). The average DVS of the obese and control group was 28.63 and 30.41, respectively and revealed a statistical significance (p = 0.0003). DDS in the obese group (3.686) was significantly lower than that of the control group (3.769)(p = 0.0253). DVS showed considerable negative relationships with BMI or waist circumference after it was adjusted for potential confounding factors. In conclusion, obese women had lower calcium intake quality, milk consumption, DVS and DDS than those of the control group. In Korean females, food intake variety did adversely affect obesity index. Further studies are needed to confirm this finding.

To assess the food intake and diet quality of middle school students who live in Kangneung area, a dietary survey using 3-day food record was conducted with 226 subjects. Seventy five percent of total food intake was in the form of plant foods and the rest in the form of animal food. Diet qualify was assessed by food group pattern, dietary diversity score (DDS), and dietary variety score (DVS). When counting the major food groups consumed, 53% of subjects had a DDS of 3 and 35% of subjects had a DDS of 4. When investigating the consumption pattern of the major five food groups, only 10.2% of subjects consumed foods from all five groups. The groups most frequently missed were dairy products (73.0%) and fruits (71.7%). On average, subjects habitually consumed 22.6 different foods daily, with the mean score of diet variety for males (22.1) being significantly lower than for females (22.9). Correlation coefficients between nutrient adequacy ratio (NAR) and DVS ranged from r=0.40 for vitamin B$_1$to r=0.61 for phosphorus. NAR also improved as the number of foods or food groups consumed increased (p<0.001). Associations between the NAR and high level of DVS was more positive than those between the NAR with DDS. When assessing the dietary quality of subjects using DDS and DVS, many people appeared not to have a desirable food intake. Therefore, to lead them to have nutritionally balanced diet, educating students and their parents on nutrients and suggesting guidelines for a desirable diet is considered to be essential so that they can intake from all of major food groups and have various foods in their diet.

This study was conducted to identify the characteristics of Korean diet in the view of food and food group intakes. The study subjects consisted of preschool children(PC), elementary school children(EC), high school students(HS), college students(CS), and adults over 30 years old living Seoul and the surrounding areas. The subjects over 30 years old were classified to 30-49 years, 50-69 years, and over 70 years. A dietary survey was conducted using 24-hour recall method and data were collected from 2392 subjects. Rice was a major contributor to many nutrients intake because of the amount of consumption. Vegetable oil made great contribution to fat intakes and eggs, squid, and anchovy supplied much cholesterol compared to other foods in all the age groups. Milk was major contributor of fat and cholesterol as well as calcium in younger age group, and seasoning gave much contribution to iron intakes. Mean dietary variety score(DVS) was 32 for EC group and 17 for subjects over 70 years, and tended to decrease along the increasing age. EC group consumed most variable number of foods of all groups but they consumed many junk foods, therefore the MAR value was low despite their high DVS value. Mean dietary diversity score(DDS) of each age group from PC group to subjects over 70 years was 4.34, 4.28, 3.79, 3.89, 3.76, 3.56, and 3.25, respectively. Food group, which was consumed below the minimum amount, was mainly fruits in all the age groups, and many subjects in HS group and over 30 years consumed dairy products below the minimum amount. From these results, age specific nutritional problems were found. PC group and subjects over 50 years seemed to need more diverse food intake than now, EC group did nutrient dense food, and HS group and subjects over 30 years did dairy products. Also, subjects took various nutrients from rice and seasoning contributed to some nutrients intakes. (Korean J Nutrition 34(5) : 568∼579, 2001)

This study was performed to develop an index assessing the overall diet quality for Korean. The study subjects consisted of preschool children (PC), elementary school children (EC), high school students (HS), college students (CS), and adults over 30 years old living Seoul and the surrounding areas. The subjects over 30 years old were classified to 30-49 years, 50-69 years, and over 70 years. A dietary survey was conducted using 24-hour recall method and data were collected from 2392 people. Newly developed Korean diet quality index (KDQI) was an index assessing the overall diet quality from the view point of balance. KDQI was based on the nutritional problems of Koreans, dietary risk factors for chronic degenerative diseases, 5 major food groups, and dietary guidelines. The ten components of KDQI were vegetables, fruits, dairy products, dietary variety score, calcium intake, iron intake, energy intake, fat intake, and cholesterol intake. The full score of each component was 10 points and the score of KDQI was calculated by summing the scores of the 10 components. When the KDQI was applied to this study subjects, the distribution of subjects KDQI scores was similar to normal distribution. Mean score of KDQI was 56.0 and the range of the mean by age was from 45.7 for the subjects over 70 years old to 60.7 for the elementary school children. The components which composed the lowest three means were dairy intake, fruit intake, Ca intake in most age groups. Mean score of DVS was one of the highest three but not for the subjects over 50 years old. After subjects with KDQI score over 70 were classified to higher poop and those with KDQI score under 40, to lower group, nutritional characteristics were compared. Energy contributions of carbohydrate, proteins, and fit, percentages of RDA for major nutrients, and dietary diversity scores were more adequate in the higher poop than in the lower group. The lower poop had more risks for chronic degenerative diseases. According to the results, KDQI was valid index to assess the overall diet quality and it could be used to detect risk group for malnutrition and chronic degenerative diseases.

This study was performed to evaluate served menu in Korean temples. Among available temples in the nation, 34 temples were carefully selected considering location and the gender characteristics. A five consecutive day menu was collected to analyse by interview between Jan 2004 and Aug 2004. Mean energy content of menu was 1633.8 kcal, with 67.3% of energy supplied by carbohydrate, 14.8% by protein and 17.9% by fat. Beans and bean products were the major contributing dishes for most nutrients. Contents of most nutrients except energy, protein and vitamin B were higher than RDA. Nutrient adequacy ratio (NAR) were 0.9-1.0 and mean adequacy ratio (MAR) was 0.9 for temples. Total number of dishes from menu was 7.3. Dietary variety score (DVS) was 26.4 and buddhist monk temples offered more diverse foods than buddhist nun temples. KDQI (Korean diet Quality Index), overall diet quality index were 0.67 and those of buddhist nun temples were better than those of buddhist monk temples. From the result of this study it was concluded that the temple diet is nutritionally well balanced, rich in dietary fiber and low in cholesterol. So it can be a healthy diet for the modern person. This is the very first study attempting the nationwide investigation of temple diet in Korea. It will be used as fundamental data to improve quality of diet to prevent modern chronic disease.

To assess the food intake and diet quality of high school students who live in Chuncheon area, a dietary survey using 24-hour recall method was conducted with 318 subjects. $71.4\%$ of total food intake was in the form of plant foods and the rest on the form of animal food. Diet quality was assessed by food group pattern, dietary diversity score(DDS), and dietary variety score(DVS). When counting the major food groups consumed, $37.1\%$ of subjects had a DDS of 3 and $48.4\%$ of subjects had a DDS of 4. When investigating the consumption pattern of the major five food groups, only $14.5\%$ of subjects consumed foods from all five groups. On average, subjects habitually consumed 26.7 different foods daily, with the mean score of diet variety for males (27.3) being significantly higher than for females (25.8) . Correlation coefficients between nutrient adequacy ratio (NAR) and DVS ranged from r=0.39 for vitamin $B_2$ to r=0.61 for phosphorus. NAR also improved as the number or foods or rna groups consumed increased (p<0.001). Associations between the NAR and high level of DVS was more positive than those between the NAR with DDS. When assessing the dietary quality of subjects using DDS and DVS, many people appeared not to have a desirable food intake. Therefore, to lead them to have nutritionally balanced diet, educating students and their parents on nutrients and suggesting guidelines for a desirable diet is considered to be essential so that they can intake from all of major food group and have various foods in their diet.
