This study conducted to assess the effectiveness of nutrition education program for elderly females with various diseases. Forty subjects(hypertension ; 20, diabetes ; 12, hyperlipidemia ; 8) out of 56 completed the 7 weeks nutrition education program. The nutrition education program was based for healthy food habits and dietary guidelines for each specific disease. It also included practicing individualized menu planning and exercising program. Energy, calcium, iron, vitamin A and ash intakes significantly increased in the hypertension group. total sodium intake did not decrease, however sodium intake per kcal decreased significantly(p〈0.05). Elderly with diabetes did not show any changes in dietary intakes. Dietary protein, plant fat, ash, and sodium intakes were significantly elevated(p〈0.05), but cholesterol intakes significantly decreased(p〈0.05) in the hyperlipidemic group. Elderly with hypertension agreed strongly with changes of food habits such as increasing milk intake, and decreasing Kimchi, soup, pickles and salty food, and table salt intakes after nutrition education. Diabetic elderly showed significantly improved food habit scores in decreasing white rice intake, sugar intake and increasing sea-weed consumption, vegetable consumption and exercise. Hyperlipidemic elderly did not show much improvement in food habit scores except in biochemical indices. However, mean serum glucose and atherogenic index decreased in the diabetic and hyperlipidemic groups after education, respectively.

The study was designed to investigate the relationship between dietary intakes and the obesity of 400 students who were the third grade in middle school in some areas of Seoul. The survey conducted from March 3 to 13 , 1993. The results obtained were summarized as follows :The average height and weight of surveyed subject were similar to that of standard ( the third grade students in middle school in Seoul, 1991) . Compared to the standard weight/height ratio, subject who belonged to overweight and obese group were 16.4% of male students, 16.1% of female students respectively. Female subjects showed higher ratio than male subjects in skipping meals, frequency of snack per day and concern about a dieting . In case of subjects who belonged to weight /height ratio was high, their speed of dining was fast and they have more concern about a dieting. Compared to the amount of the nutritional intakes of RDA, calcium intakes of male and female subjects were deficient. Especially iron intakes of female subjects were deficient. In takes of Calorie (p<0.01) protein(p<0.05) and fat 9p<0.01) of obese group were higher those of non-obese group. Obese group showed good appetite and overeating also . Correlation analysis showed that obese group seemed to the closely associated with relative body weight of parents, family income, frequency of meals per day, frequency of meals per day, frequency of snack per day, speed of dining and overeating .

This study was performed to assess the nutrient intakes and diet quality of rural middle school students provided with and without the national school lunch program(NSLP). The data on dietary intakes were obtained by using food record method questionnaires which were collected from 340 rural middle school students provided with(n=177) and without (n=163) NSLP. Diet quality was accessed by NAR(nutrient adequacy ration), MAR(mean adequacy ration), and INQ( index of nutritional quality). Total energy intakes of the boys were 2123 kcal with NSLP and 1857 kcal without NSLP. Total energy intakes of the girls were 1913 kcal with NSLP and 1814 kcal without NSLP. Phosphorus, vitamin A, vitamin E, ascorbic acid, thiamin, riboflavin, and niacin intakes were above the RDA in the NSLP group. For those without NLSP, phosphorus, vitamin E, thiamin intakes were above RDA, however, calcium, iron vitamin A, vitamin $B_6$ were less than the RDA. The mean adequacy ration(MAR), an index of dietary quality was 0.69(with) 0.62(without) for males and 0.62(without) for females The indexes of nutritional quality(INQ) were over 1 for most nutrients except calcium, vitamin A, vitamin B$_2$ and zinc. The study showed that total daily energy and nutrient intakes were significantly higher in students provided with than those without school-lunches. Thus, the school-lunch program is recommenced and necessary to improve the nutritional status of middle school students.

BACKGROUND/OBJECTIVES: This study aimed at evaluating the dietary intakes of Korean adolescents affected by food insecurity, in comparison with those who were food secure. SUBJECTS/METHODS: The study used one day 24-hour dietary recall data from the $6^{th}$ Korea National Health and Nutrition Examination Survey. The study subjects consisted of 1,453 adolescents of whom 695 were middle school-aged and 758 were high school-aged. Food security status was assessed using the 18-item questionnaire. Nutrient intake was evaluated in terms of nutrient density, insufficient intake, and excessive intake for selected nutrients, in addition to meeting the appropriate range for total energy intake and energy intakes from carbohydrate, sugar, protein, fat, and saturated fatty acids. Food intake was evaluated in terms of food group servings and dietary diversity score (DDS). RESULTS: The percentages of food insecurity were 11.1% for middle school-aged adolescents and 16.8% for high school-aged adolescents. Food insecure middle school-aged adolescents had higher intake of carbohydrate (P = 0.006) but lower intake of fat (P = 0.010) and saturated fatty acids (P = 0.005) than their food secure counterparts although the intake of both groups was in the recommended ranges. Nutrient intake among high school-aged adolescents was generally similar regardless of food security status. Both food secure and insecure adolescents showed insufficient intake of vitamin A, vitamin C, and calcium, and excessive sodium intake. They additionally had low prevalence of meeting appropriate intake ranges for energy, carbohydrate, and sugar. Food intake in terms of food group servings and DDS was also similar regardless of food security status among both age groups, with low intakes of foods from fruit and dairy groups. CONCLUSIONS: Except for a few nutrients among the middle school-aged adolescents, dietary intakes among Korean adolescents did not differ by food security status in this study.

This study was designed to evaluate the nutritional status and dietary problems of obese elementary students consuming unbalanced diets. Blood parameters, body-image perceptions, taste preferences, and nutrient intakes of 40 obese elementary students with unbalanced diets were compared to those of 40 additional obese elementary students as a control. The averages for age, height, weight, and obesity index were 11.5 years, 142.0 cm, 51.0 kg, and 35.4% in the study group and 11.8 years, 144.0 cm, 53.5 kg, and 36.3% in the control group, respectively. The major disliked foods by the students in the study group were vegetables (65%) particularly Kimchi (15%), as well as fish(15%), and pulses (10%). Mean serum cholesterol, blood glucose, GOT/GPT, and hemoglobin levels were 175.1 mg/dL, 89.2 mg/dL, 24.1/18.9 IU/L, and 14.3 g/dL in the study group and 182.8 mg/dL, 91.3 mg/dL, 28.3/33.9 IU/L, and 14.7 g/dL, in the control group, respectively. Approximately 60${\sim}$80% of the subjects responded that they eat a meal everyday, and the remainder skipped at least one meal. The preference for salty tasting foods was significantly lower in the study group, but the preference for hot tasting food was higher as compared to the obese control group(p<0.05, p<0.05). The daily energy intakes of the study and control groups were 1,768.3 kcal and 1,572.7 kcal, respectively, but there was no significant differences between them. Daily intakes of animal protein, fat, animal fat, and vitamin $B_2$ were significantly higher in the study group than in the control group. In conclusion, this study found that obese children consuming unbalanced diets strongly disliked vegetables, particularly Kimchi, as well as hot tasting foods; however, they preferred salty foods. Daily intakes of animal protein and fat were higher in the study group as compared to obese children not consuming unbalanced diets.

Objectives: This study evaluated dietary intake and food sources of essential fatty acids in Korean adolescents. Methods: This study was comprised of 3,932 adolescents (9-18 years) who participated in the 2016-2021 Korea National Health and Nutrition Examination Surveys. Dietary intake and food sources of essential fatty acids, including alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and linoleic acid (LA) were evaluated using data obtained from one-day 24-hour dietary recall. The proportions of adolescents consuming ALA, EPA + DHA, and LA above or below the adequate intake (AI) of the 2020 Dietary Reference Intakes for Koreans were calculated. All statistical analyses accounted for the complex sampling design effect and appropriate sample weights. Results: The mean intakes of ALA, EPA, DHA, and LA among Korean adolescents were 1.29 g/day, 69.6 mg/day, 166.0 mg/day, and 11.1 g/day, respectively. Boys had higher intakes of all essential fatty acids compared to girls. By age group, adolescents aged 15-18 years showed lower intakes of EPA and DHA compared to adolescents in younger age groups. The 9-11-year-old adolescents had lower intakes of ALA and LA than older adolescents. The proportions of adolescents who consumed more than AI were 35.7% for ALA, 30.4% for EPA + DHA, and 41.5% for LA. Adherence to the AI for ALA did not differ by sex or age group, although boys showed a lower adherence to the AI for EPA + DHA than girls. Major food sources for ALA and LA were plant-based oils, mayonnaise, pork, and eggs. Mackerel was the most significant contributor to EPA and DHA intake (EPA, 22.6%; DHA, 22.2%), followed by laver, squid, and anchovy. Conclusions: The proportion of Korean adolescents who consumed EPA + DHA more than AI was low. Our findings highlight that nutrition education emphasizing an intake of essential fatty acids from healthy food sources is needed among Korean adolescents.

The purpose of this study is to investigate the dietary intakes and nutritional status in total gastrectomized patients. We assessed the nutritional status by dietary intake, anthropometric data and biochemical data. And we also checked the subjective postprandial symptoms and gastrofiberscopy to detect the reflux esophagitis in 22 patients who were free of tumors for more than 1 year after total gastrectomy by the three different reconstruction methods(Loop esophagojejunostomy with A-loop tie/ Roux-en-Y esophagojejunostomy/Roux-en-Y esophagojejunostomy with Paulino pouch). Any patients were not in malnutrition status in respect to biochemical data. By assessing the dietary intake, the average daily calorie intake was 1848.2$\pm$440.2kcal, it was 105.9$\pm$23.8% of energy requirement. But there was weight loss in 21 patients of 22 patients after operation and the weight loss was 12.8% of preoperative weight(61.0$\pm$7.9 vs. 53.5$\pm$6.7kg, preoperatively vs. at the time of study). This may suggest that continuous nutritional care is necessary after total gastrectomy to promote sufficient calorie intake, keeping good nutritional state. There were no significant differences between the methods of reconstruction and dietary intakes or nutritional status. Endoscopic esophagitis was more frequently found in patients of loop esophagojejunostomy than any other reconstruction methods(p<0.001), but it didn't show any effect on the dietary intakes.

In Korea, there has been a rapid increase in the number and proportion of elderly people, especially in rural areas, due to improvements in the standard of living and medical technology. One of the main health problems for the elderly people is dental health, which can cause nutritional and health problems. Thus, in this study, the dental health status and health status in relation to nutritional intake were analyzed. A total of 155 rural-dwelling elderly people (68 males, 87 females) over the ages of 65 participated in this study. The subjects were classified into three groups; the no denture no teeth group, denture user group, and natural teeth group. The dietary intake, biochemical health status, and anthropometry were evaluated. Can-pro 3.0 was used to assess dietary intakes and the SPSS 12.0 program was used for statistical analysis. The results showed that the natural teeth group had better nutritional and dietary intake status than the no denture no teeth group. The dietary assessment showed that there were differences in food intakes among the groups, which depended on their dental health status. In conclusion, dietary management is required for the elderly since each group has a different ability to chew food depending on their dental health status. In addition, the elderly will need different therapeutic diets because of the high prevalence of chronic degenerative diseases.

This study was performed to investigate dietary habits, and to evaluate the relationship between nutritional status and certain blood parameters in premenopausal and postmenopausal women living in Daejeon. Adult Korean females(n=110) that had visited the Health Promotion Center of Eulji University Hospital were analyzed. We examined blood parameters, body composition, and life style factors such as food habits and physical activity in pre- and post-menopausal women. The collected data were then analyzed to evaluate the various items. Overall, there were no differences between the pre- and post-menopausal women for food habit score, or for intakes of energy, protein, Int, iron, vitamin A, vitamin $B_1$, vitamin $B_2$, niacin, vitamin C, and calcium. However, carbohydrate intake was significantly higher in the postmenopausal women than in the premenopausal women. The Dietary Reference Intakes for Koreans(KDRIs), in terms of energy, fat, calcium, vitamin A and vitamin $B_1$, were less than 100% in both the premenopausal women and postmenopausal women. All intakes of protein, iron, vitamin $B_2$, niacin, and vitamin C satisfied the KDRIs in both groups. Finally, the postmenopausal women had higher serum fasting blood glucose, total cholesterol, LDL-cholesterol and alkaline phosphatase levels than the premenopausal women.
