Purpose: Number of the old-old elderly is rapidly increasing in Korea, but it is unclear whether there are differences between old-old and young-old elderly in nutritional status, nutrient intakes and health status. The gender differences in Korean elderly in these conditions also remains unknown. This study, therefore, investigated gender-associated differences in nutritional, health status and nutrient intakes and how they are related among young-old and old-old homebound elderly. Methods: Two hundred and eighty elderly who were attending a local elderly welfare center were recruited. Evaluation included demographic, nutritional and health status related data, nutritional intakes, and life style related factors including physical activity. Results: Of the 280 subjects, old-old were 147 (52.5%) and young-old were 133 (47.5%). Male old-old elderly had more often abdominal obesity than female old-old, but male old-old more often had malnutrition than female old-old. There were few differences in nutrient intakes between old-old male elderly and female elderly after energy intakes were controlled. Male old-old more often had less intake of beta carotene and Vitamin A than female old-old. On the other hand, male old-old elderly more often had hypercholesterolemia and hypertension than male young-old. Conclusion: Male old-old may be at a greater health and nutritional risk than female old-old. Targeted nutritional intervention for male old-old emphasizing antioxidant nutritional intakes may be warranted.

BACKGROUND/OBJECTIVES: The nutrition of the elderly depends on various factors. Oral health, especially oral dryness, can be an important risk factor. In this study, we attempted to determine whether dry mouth is associated with compromised nutrient intakes. SUBJECTS/METHODS: A total of 120 participants aged 65-86 yrs (mean age: 69 ± 1 y) were included in this study. Demographic and health-related characteristics, living status, meals, number of medications, medical conditions, chewing ability, and quality of life, the Oral Health Impact Profile (the OHIP-14) were assessed. We performed one day 24-hr recall assessment for nutrient analyses. The differences of the means between the dry-mouth and non-dry-mouth groups were analyzed. Elderly subjects with xerostomia-induced dry mouth were classified as those who reported at least one dryness symptom on a questionnaire. RESULTS: A significant difference in population distribution was observed among the elderly who took medications for hypertension, diabetes and osteoporosis and was significantly higher in the dry-mouth group (70.2%) than in the non-dry-mouth group (44.4%) (P = 0.005). Compared with the non-dry-mouth group (50.8%), a significantly higher proportion (73.7%) of participants in the dry-mouth group took multiple medicines (≥ 4 medications) (P = 0.019). The intakes of vegetable fat, vitamin E, folate and water in the dry-mouth group were lower than in the non-dry-mouth group. The intakes of fluoride and ω-3 fatty acids were significantly lower in the dry-mouth group than in the non-dry-mouth group. CONCLUSION: The participants in the dry-mouth group exhibited low nutrient and water intakes. It is recommended that the elderly with dry mouth should drink sufficient water and receive targeted and specific nutritional guidance to prevent malnutrition.

This study was conducted to evaluate the nutrient intakes and the physical activities of mentally retarded persons (MRPs) accommodated in welfare institutions. A total of 194 cases of MRPs (130 males and 64 females) were surveyed through interviews of the 35 caregivers of the institutions during the period from March 2 to 12, 2005. The mean age of the 2nd degree is the highest, and the duration of institution stay of the 2nd degree is the longest. There were no significant differences in height, weight, but there were still significant differences in BMI by the degree of handicap. The MRPs with the 1st degree handicap consumed less nutrients than the MRPs with 2nd or 3rd degree handicaps, except for vitamins C and E. The mean activity factor was $1.737{\pm}0.422$ meaning 'active'. Among the comparative groups, the activity factor of the 2nd handicap degree MRPs was the highest. Note that the percentage of protein is the lowest in the case of the 1st degree handicap. The intake of the folic acid, in particular, was less than the Estimated Average Requirement (EAR) in case of all the MRPs while that of vitamin C, riboflavin and calcium was less than the EAR in case of $65{\sim}80%$ of the MRPs. MRPs with higher activity factors showed higher intakes of most nutrients except vitamin C. MRPs with higher marks in the 'balanced dietary habit' field showed more nutrient intakes. More consumption of vegetables and fruits by the MRPs was recommended. Also, more efficient dietary guidance was recommended for the MRPs.

The purpose of this study was to compare nutrient intakes and the serum iron status of 74 Food and Nutrition major, and 45 non-major, female students at a university in Incheon. This cross-sectional survey was conducted using a self-administered questionnaire and the data were analyzed by the SPSS 10.0 program. The nutrient intake data collected from three-day dietary recalls were analyzed by the Computer Aided Nutritional Analysis Program. Anthropometric data and hematological indices of iron in the blood were measured. Average heights, weights, body fat and mid-upper arm circumference of Food and Nutrition major and non-major female students were 160.3 cm, 53.5kg, 25.8%, 23.7cm and 159.8cm, 55.5kg, 28.9%, 24.8cm, respectively. There were significant differences in body fat percentage and mid-upper arm circumference between the major and non-major students. In all subjects, daily dietary intakes of nutrients- except protein, vitarrlin B1, vitamin C and phosphorus - were lower than the Korean RDA. In particular, calcium and iron intakes of all subjects were under 60% of the Korean RDA. Values of RBC (red blood cell) count, Hb (hemoglobin), Hct (hematocrit), MCV (mean cell volume), MCH (mean cell hemoglobin), and MCHC (mean corpuscular hemoglobin concentration) of the non-major students were significantly higher compared to those of the major students. The diastolic blood pressure of the major students was negatively correlated with MCV, MCH, TS, and serum iron levels. Triceps skinfold thickness, mid-upper arm circumference and waist-to-hip ratios of the non-major students were negatively correlated with TIBC. Fat intake was positively correlated with RBC, Hb, Hct, and TIBC (total iron binding capacity) in the major students. Vitamin C intake was positively correlated with serum iron in the major students. Carbohydrate intake was positively correlated with Hb, Hct, and MCHC in the non-major students. Niacin and iron intakes were positively correlated with Hb and Hct in the non-major students. Therefore, nutrition education is necessary for female university students to improve nutritional status and to practice optimal nutrition strategies. (Korean J Nutrition 35(9) : 952~961, 2002)

This study was performed to investigate Apolipoprotein E phenotypes and the relationship among lipid levels, nutrient intakes, lifestyles and risk factors between subjects with and without hyperlipidemic risk. The data were collected from 675 industrial male workers who had completed annual medical examination. Compared to the normal group, the hyperlipidemic risk group in Apo E3 and E4 had significantly higher BMI (p < 0.05) and showed significantly higher body fat (%), waist circumference and WHR in all types of Apo E (p < 0.05). In addition, the hyperlipidemic risk group had significantly higher total cholesterol, LDL-cholesterol, triglyceride and AI than the normal group in all types of Apo E (p < 0.05). Intakes of protein, calcium, phosphorus, iron, vitamin A, vitamin B1, vitamin B2, vitamin C and niacin in Apo E3 were significantly lower in the hyperlipidemic risk group than in the normal group (p < 0.05). In the logistic regression analysis, after adjustment for other factors, Apo E2 + E4, waist and WHR were the significant risk factors associated with hyperlipidemia, but protein intakes were associated with significantly lower risks of hyperlipidemia (p < 0.05). In conclusion, genetic factor (Apo E2 or Apo E4), anthropometric index and nutrient intake seem to influence hyperlidemic risk. Further studies and efforts will be needed to evaluate the independent relationships among hyperlipidemic risk factors.

The purpose of this study was to determine the effects of nutrient intake, screen time (television viewing and computer and/or video games) and physical activity on obesity in preschool children. Recruitment began in January 2008 by distributing letters to mothers who had children aged 6 years enrolled in daycare. Dietary intakes were obtained from the children's mothers, using the 24-hour recall method. The average height and weight of the children were 114.2 cm and 20.3 kg, respectively. Mean age, body weight, height and Kaup index were not significantly different between groups consisting of boys or girls. Assessment by the Kaup index showed that 14.0% of children were underweight, 69.0% were normal weight, 13.0% were overweight, and 4% were obese. The daily intakes of calcium, potassium, fiber, and folic acid in the group of boys were 77.7%, 58.5%, 80.4% and 88.9% respectively. as compared with the DRIs. The daily intakes of calcium, potassium, fiber, and folic acid in the group of girls were 77.7%, 58.5%, 80.4% and 88.9%, respectively. as compared with the DRIs. Intakes of protein, phosphorus, iron, zinc, vitamin A, thiamin, riboflavin, niacin, vitamin C, and vitamin E were higher than the DRIs. There were no difference among 3 groups (underweight, normal, overweight) in energy or nutrient intake. Preschool children with screen time (TV viewing and computer and/or video games use time) of >2 hours per day had significantly higher Kaup index values, and intakes of energy, carbohydrate, folic acid and zinc. In conclusion, preschool children with reported screen time (TV viewing and computer and/or video games use time) of >2 hours per day were fatter. Therefore, we need further investigate the relation between diet and screen time in preschool children to improve future nutrition education programs. Further studies are required to explore the effects of food intake and screen time (TV viewing and computer and/or video games use time) over a longer period of time.

Although fine dust pollution in Korea is increasing, there is no information regarding nutritional standards for fine dust-related disease patients. This study analyzed the food and nutrient intake status in adult men with disease associated with fine dust in the area with the increased level of fine dust pollution using the sixth and seventh Korea National Health and Nutrition Examination Survey (2013-2017). The daily intakes, and average nutrient adequacy ratio (NAR) and mean adequacy ratio (MAR) values of energy were significantly increased in the control group compared with patient groups. Compared with the control group, protein, fat and cholesterol intakes were significantly increased in the patient groups. Daily intakes of cereals and grain products in the control group were increased, whereas seasoning intake was decreased in the control group compared with patient groups. The patient groups had low daily water and vitamin B₁ intakes, and the niacin intake of patient groups was significantly lower than that of the control group. Nutrition density and nutritional quality of vitamin C were significantly reduced in patient groups. This study can be used as basic data for nutrition education that emphasizes sufficient calorie, water and antioxidant vitamin intakes for patients related to fine dust pollution.

This study was conducted to figure out the differences of the BMI, blood lipids, blood pressure and nutrient intakes by serum insulin concentration among adults in Korea. Ninety-three subjects(male : n=37, female : n=56) participated in this study. The subjects were grouped by serum insulin concentrations into two groups-hyperinsulinemia group(n=17) and normoinsulinemia group(n=76). Anthropometric measurements, blood lipid profiles, blood pressure, oral glucose tolerance test, and daily nutrient intakes were analyzed. And serum glucose and insulin secretion pattern as shown through and oral glucose tolerance test were performed. BMI (p<0.05) and WHR(p<0.01) were significantly higher in hyperinsulinemic group than in normoinsulinemia group. There was no differences in fasting blood glucose level between groups, but total glucose area (p<0.001) and insulin glucose resistance(p<0.001) were significantly higher in hyperinsulinemia group than in normoinsulinemia higher in hyperinsulinemia group, but HDL-cholesterol(p<0.05), and systolic blood pressure(p<0.05) were significantly higher in hyperinsulinemia group, but HDL-cholesterol(p<0.001) was significantly lower in hyperinsulinemia group. They showed significant differences in energy, carbohydrate, potassium, riboflavin, niacin and dietary fiber intakes(p<0.05), the intake of those nutrients were low in normoinsulinemia group. Further investigation is necessary to determine the effects of amounts and types of carbohydrate and dietary fiber on serum insulin concentrations.

The purpose of this study was to develop the website-based program for individual meal planning. The program consisted of the basic information of clients, dietary habits, analysis of nutrient intakes and menu planning. The first part of the program consisted of general information such as general characteristics and anthropometric data of clients. The second part was designed to investigate the dietary habits, food intake frequency, nutrition knowledge, and drinking and smoking habits of the clients. The third part consisted of analysis of nutrient intakes including three major nutrients, calorie intake by foods and alcohol, and ratio of individual fatty acid intake. Nutrient intakes was evaluated by comparing with dietary reference intakes. In the final part, the program included the menu planning by using standard recipe. This system was also designed to insert, remove or change the food items or amount according to the user need. It is expected that the development of a meal planning system based on the internet can facilitate the professional dietary counseling, and thus help to improve the health of people.

A study about health status of the elderly in rural area was performed with 110 home-bound elderly. The results obtained by questionaires and personal interviews recall were as follows. 1) Subjects were 68.6 years of age on average. They revealed the physical tendency of not overweight but high blood pressure. 2) We found that seniors who live alone in rural area were more than in urban area. 3) Average daily intakes of energy and protein of rural elderly were lower than the Korean RDA and the intakes of Ca, riboflavin and niacin in female were also lower. 4) Nutrient intakes were related to family income, food expense, smoking amount, drinking frequency and duration of exercrse, which suggested the needs of nutrition education for the seniors and meal services especially for the low-income elderly.
