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 purposes of this study were to assess dietary intake obtained by easy method and to compare dietary behavior of house wife and female college students in Yanbian. The subjects consisted of 276 house wives and 228 female college students. Mean daily energy intake of house wives was 1926.0kcal and that of female college students was 1949.0kcal. Calcium intake as NAR(Nutrient adequacy ratio) was lowest in house wife and female college student. Iron intake was also low in subjects and lower in female college student than in house wife. Meal frequency per day was regular in subjects. Skipping meal time in subjects was breakfast and snaking time was late evening generally. Frequency of eating out was rare in most subjects and 60.6% of subjects preferred chinese food in eating out, while house wives preferred Korean food than female college student in eating out. The vegetables were preferred than meat or fish and used by fried in sauces. Hot and sour tastes were more like than greasy taste in subjects. Nutrient intake levels and dietary behaviors of house wife were to be like as those of female college students in general. BMI(Body mass index) was lower in female collage students than house wives, similarly in Korean. According to these results, house wives and female college students in Yanbian had similar dietary patterns. Calcium intake was tend to be low and dietary pattern was regular, dietary qualifies of subjects were adequate. Nutrient intake and dietary pattern in Yanbian were to be like as in Korean, and the Korean-Chinese in Yanbian maintained traditional dietary pattern.

To assess the quality of nutrient intake by area of Korean adults, a dietary survey with the 3-day record method was obtained from 324 subjects aged 40 years and older but younger than 70 (52.4 $\pm$ 8.7) living in a rural area (Ansung) and suburban area of a middle-sized city (Ansan). The quality of nutrient intake was assessed by analyzing Nutrient Adequacy Ratio (NAR), Mean Adequacy Ratio (MAR) and Index of Nutritional Quality (INQ). The average daily mean energy intakes were 1,832 ㎉ for Ansung and 1,842 ㎉ for Ansan, respectively. Daily intakes of fat for Ansung and Ansan subjects were 40.9 and 40.3 g, and those for protein were 75.1 and 73.1 g, respectively. The overall calorie: protein: fat ratio (CPF) of energy intake was 63 : 17 : 20. Daily mean intakes of protein, fat, calcium, phosphorus, iron, potassium, carotene, sodium, thiamin, and niacin were significantly higher in Ansung residents than in Ansan subjects (p < .05). The average intakes of energy, calcium, vitamin A were lower than Recommend Dietary Allowance (RDA) in both areas. Note, over 30% of the study subjects had less than 75% of RDA of calcium, vitamin A and riboflavin. The MAR was higher in Ansung than Ansan residents (0.86 and 0.85, respectively; p < .05). INQs were over 1 for most nutrients except calcium (0.87), and that of calcium and phosphorus was each significantly higher in Ansung than Ansan subjects. Based on these results, nutrient intake quality of subjects aged 40 to 69 years living in the surveyed rural area is comparable to that of semi-industrialized suburban area in Korea. Dietary deficiency in all of calcium, vitamin A, and riboflavin, however, was a common problem for both rural and suburban residents.

This study was conducted to investigate on bone density and nutrient intake of university students in Seoul area. Nutrient intake data were obtained by using the 24-hour recall method to evaluate the usual diet of the subjects. BQI(bone quality index) of the subjects was measured by an Quantitative Ultrasound (QUS). The results are summarized as follows: The average height, weight, BMI of the male and female student were 173.3 cm, 68.5 kg, 22.7; 161.4 cm, 54.2 kg, 20.8, respectively. The BQI and Z-score of the subjects were 99.50, -0.69 in male student group, and 82.6, -1.15 in female student group, respectively. Normal, osteopenia and osteoporosis percentage by bone status were 73.8%, 24.9%, 1.3% in male student group, and 39.8%, 57.6%, 2.6% in female student group, respectively. Energy intake of male and female group were 71.7%, 79.1% of EER(estimated energy requirement) respectively. Fiber, Ca, Vit $B_2$, niacin, folic acid, Vit C intake were less than RI(recommended intake) and protein, phosphorus intake were higher than RI in subjects. Nutrient intake were not significantly related with BQI in male and female groups generally.

BACKGOUND/OBJECTIVES: This study investigated nutritional status of the elderly with dementia in a care facility with the aim of improving the meal quality of the facility. SUBJECTS/METHODS: Data were collected from 30 dementia patients aged more than 65 years in a long-term care facility in Hongseong. The data were obtained from questionnaires and medical records. The food intake data was obtained using food photographs and the nutrient intakes were calculated using the CAN-Pro 5.0. The data were compared with the dietary reference intakes for Koreans (KDRIs). The nutrient density, diet quality such as nutrient adequacy ratio (NAR), mean adequacy ratio (MAR), and index of nutritional quality (INQ), as well as dietary diversity score (DDS) were evaluated. The data were analyzed using SPSS statistical programs. RESULTS: The average daily energy intakes for men and women were much lower than the estimated energy requirements of the KDRIs. The average intakes of energy and most nutrients in the general diet group were significantly higher than those of the other two groups. Significant differences in diet quality and diet diversity were observed according to the meal type groups. The NARs of some minerals (calcium, iron, and zinc) and vitamins (vitamin $B_6$ and folic acid) were less than 0.5 in all study groups. The NARs of protein, iron and MAR of the general diet group were significantly higher than those of the liquid diet group. The DDS scores of meats, fruits and diary food group were very low in all meal type groups, meaning that the diet qualities of the study subjects were not appropriate in all meal type groups. CONCLUSIONS: The food intakes of the study groups showed some limitations by a direct comparison with KDRIs because of the very low physical activities of the study subjects. The diet quality and diet diversity indices suggest the need for improvements in the nutritional quality in all types of diet. Overall, new intervention strategies targeting facility residents with dementia in Korea are needed as soon as possible.

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 measure the effects of counseling for hypertension patients. the subjects were 44 hypertension patients who visited the general, hospital, located in Daegu, to receive medical treatments. Among 44 hypertension patient, 22 patients received the nutrition counseling three times for 8 weeks and the rest of the patients didn't as a non-counseling group(control group). The lifestyle, food habit, nutrient intakes, anthropometric measurements, and body fat and blood pressure as a main index were analysed before and after the nutrition counseling. The result after the nutrition counseling are as follows: 1) Body mass index(BMI), systolic blood pressure(SBP) and diastolic blood pressure(DBP) were significantly decreased in women(p<0.05). 2) The food habit score and nutrition knowledge score were dramatically increased(p<0.001). 3) The calcium intake was significantly increased in women(p<0.01). And energy, carbohydrate and fat intakes were decreased both men and women but there were no significant differences. The calcium intake as an Index of nutrition quality(INQ) and nutrient adequacy ratio(NAR) were significantly increased 5) Fat and cholesterol intakes in a group whose blood pressure reduced were significantly decreased compared with a group that had the same or higher blood pressure. These results showed that a well-planned nutrition counseling program would reduce the risk of cardiovascular disease.

This study was conducted to investigate effects of nutrition education and exercise intervention on health and diet quality of middle-aged women. The subjects were 209 women who wanted to involve in the health promotion program run by Jincheon-Gun Health Center. Nutrition education was given once a week and dance sports were done twice a week for 3 months. Nutrient intakes were assessed by 24-hour recall method and food records. Dietary habits and nutrition knowledge were investigated by self-administered questionnaires before and after the intervention program. Body and blood compositions were measured before and after the program. The nutrient adequacy ratio (NAR) was significantly increased in energy, protein, vitamin A, vitamin B2 and calcium, mean adequacy ration (MAR) was significantly increased (p < 0.05), and also the index of nutritional quality (INQ) was significantly increased in protein (p < 0.01). Percent (%) RIs of protein (p < 0.01) and calcium (p < 0.05) were significantly increased and body weight (p < 0.001), body fat (p < 0.01), soft lean mass (p < 0.01) and BMI (p < 0.001) decreased. Over the 3-month study, there was a significant trend toward higher HDL-C and albumin levels and lower LDL-C level (p < 0.001). The results showed that nutrition education and exercise intervention could improve the body health and the diet quality.
