The relationship between cognitive function and dietary patterns in Korean elderly women was investigated in this study. Twenty-four-hour dietary recall and cognitive function tests were performed in 170 elderly women aged over 60 years. Average age of the subjects was 71 years and the average number of family members was 3.3. Most of the subjects had less than seven years of education and their monthly income was much lower than the Korean average. Most of the subjects engaged in regular exercise and did not indulge in drinking and smoking. The average cognitive function score of the subjects was 58.4. Most of the subjects appeared to consume insufficient amount of food ; average intakes of energy, Ca, iron, vitamin A, and riboflavin were lower than RDA for the elderly. Cognitive function score was positively related to education level and regularity of exercise. Also, cognitive function score had a strong relationship with food intake such as total amounts of foods, fish and shellfish, milk and dairy products, total animal food, fruit, bread and sugar. Energy, protein, Ca, p, riboflavin, and niacin were also shown to have positive relationships to cognitive function score, while carbohydrate caloric ratio had a negative relationship with cognitive function. According to the results of multiple regression analysis, factors that most influenced on cognitive function were education level and riboflavin intake. The subjects who had more than seven years of education had significantly higher cognitive function scores than those with no school education. And cognitive function scores f3r those who consumed more than 2/3 of the RDA for most nutrients were significantly higher than the ones fir the subjects who consumed less than 2/3 of the RDA. These results suggest that proper education and adequate nutrient intake in quantity and quality by achieving food diversity are essential in maintaining cognitive function in later life (Korean J Nutrition 31(9) : 1457-1467, 1998)

Elderly Koreans living in Muju Gun, Jeonbuk were divided into two groups with ages(65~74 years old group & over 75 years old group) and surveyed with questionnaire to investigate their dietary status and those factors affected with ages. The score of food habit in both sexes showed a falling tendency as their ages increased. Compared with elderly men, elderly women showed lower quality of diet. Elderly Korean were more consumed cereals and green vegetables than milk, egg, meat & fish, seaweed and fats & oils. As education level increased, the food habit score showed a rising tendency. The correlation coefficient between the score of food habit and education level was positive in illiterate and school graduates. The score of food habit of living together with their family was higher than those of living alone or living with their spouse. As household income increased, the food habit score showed a rising tendency. In the case of self consciousness of socioeconomic status was middle, food habit score is higher than those of very low. Dental status of eldery people did not affect food habit score. Palatability showed no significant correlation with age. Elderly Koreans prefered sweet taste than salty, sour, and bitter taste.

Evidence for the effects of different health behaviors, including diet, in elderly diabetes is currently limited. The aim of this study was to compare the quality of diet and health behaviors in Korean elderly T2DM patients, using a glycemic control. T2DM elders(>65 yr, n=48) were recruited and categorized by the concentration of glycated-hemoglobin HbA1c; subjects with HbA1c<7% were the good control(GC) group, and subjects with $HbA1c{\geq}8%$ constituted the poor control(PC) group. General characteristics, self-management behavior questionnaires, and 3-d diet records were all collected and assessed. No significant differences in general characteristics between GC and PC were detected, with the exception of a higher level of education in GC(p<0.05). A twofold longer duration of diabetes was observed in PC as compared to GC(p<0.01). The GC group did exercise for a longer time(p<0.001), and had an earlier beginning of diabetes self-management education (DSME) by healthcare practitioners using a team teach as compared with the PC group(p<0.05). The total dietary quality index(p<0.001) and individual index for carbohydrate(p<0.001) or vegetables and fruit(p<0.05) were better in GC than in PC. Therefore, the earlier DSME including intensive exercise and balanced diet selection should be expected to improve glycemic control in diabetic Korean elders.

The purpose of this study was to examine the relationship between nutrient intake and bone mineral density (BMD) of elderly women in Daegu, Korea. In this study, the bone mineral densities of 101 elderly women in Daegu were measured, and their nutrient intake, dietary habits, and maternal factors were determined through a survey. The subjects were divided into the normal group, the osteopenia group, and osteoporosis group to find out if there is a correlation between bone mineral density and maternal factors, dietary habits, and nutrient intake through their T-scores, analyzed according to the standards of WHO. Classification by T-scores of the participants were the normal group 25.7%, the osteopenia group 39.6%, the osteoporosis group 34.7%. Menopause age of the osteoporosis group was lower, postmenopausal period was longer, and last delivery age was significantly higher than the normal group (p<0.05). Osteoporosis group had a lower percentage of 'everyday' fruit and vegetable intakes and higher percentage of 'never' dairy intake than of the normal group. Vitamin A, vitamin $B_1$, and vitamin $B_2$ intakes of participants in the osteoporosis group were lower than those in the normal group (p<0.05). In conclusion, nutritional education is necessary to encourage high intake of milk and vegetables and fruits along with calcium, vitamin A, $B_1$, and $B_1$ intakes and low intake of sodium for the prevention of elderly women's osteoporosis.

The purpose of the study was to investigate the influence of salt (NaCl) recognition threshold and pleasant salt concentrations of Korean rural elderly subjects on preference of salty food as well as food group consumption patterns. The subjects were 213 elderly people (male 71 and female 142) over 65 and under 90 yr of age from Sunchang area. The higher values were found with male subjects in the areas of basic taste recognition threshold and pleasant concentration level of salt. The taste sensitivity scores of male subjects did not decrease with the increasing age, but female subjects exhibited a significant decrease with the age. The major determinant factor of salt preference of the elderly subjects in this study appeared to be personal pleasant concentration of salt rather than salt recognition threshold level and this trend was more evident in males than in females. The subject group of lower salt pleasant concentration i.e. consuming less salt showed the higher number of fruit and fruit juice intakes per week, and higher MNA (define this) scores were implying that they display more desirable nutritional status. Therefore, nutritional education focused on not only a variety of food consumption but also lowering pleasant salt concentration levels is advised to improve the quality of nutrition in the elderly.

The purposes of this study was to analyze the operational difference of foodservice center for homebound elderly by the presence of the dietitian. The questionnaire was developed to measure all variables for menu management and distributed to 103 meal service centers in charge of congregate meal service program and 57 centers for home-delivered meal service program. The data of 160 centers in charge of congregate meal service and home-delivered service centers were usable for analysis. Statistical data analysis was completed using the SAS 8.1 package program for descriptive analysis and chi-square test. Only 21.9% meal service centers had dietitians, what is more, they were not professionals who did menu management but foodservice managers, volunteers, cook or social workers. The current foodservice programs for the homebound elderly were operated without professional. In the part of menu managemet, dietitians were more actively involved in menu planning in the elderly foodservice center in the presence of the dietitians. The performance level of healthcare service was not significantly different, but the nutrition education in the elderly foodservice center with the dietitians was more frequently performed than that without the dietitians(p<0.05). In the food purchasing and food production management, the significant differences were shown that in the elderly foodservice centers in the presence of the dietitians, the proportion of the contract purchasing was significantly higher than that of direct purchasing(p<0.01). In food sanitary management, the significant differences were not shown in the part of management of keeping meal for identifying the cause of food-borne illness and left-over, but the sanitation education for the foodservice employees was performed more frequently by the presence of the dietitians(p<0.01). In conclusion, the foodservice management was more systematically conducted in the elderly foodservice centers in the presence of the dietitians than that without dietitians. The elderly foodservice program has offered the health-related support for homebound elderly. Although there were several problems in elderly foodservice management, the program delivered well-targeted, effective, and efficient nutrition services and wide range of supportive service to the at-risk older population. It needs to be managed by professional for the improvement in the elderly foodservice.

Critical evaluation of energy intake data from dietary studies is difficult but important. To investigate the underreporting of total energy intake, we analyzed the one-day dietary intake data collected by 24-hour recall method from 550 elderly Koreans aged 60 years or older. Underreporting was addressed by computing the ratio of energy intake (EI) to estimated basal metabolic rate (BMRest). EI : BMRest ratio was found to be 1.38 for, men and 1.33 for women, with about 14% of men and women classified as underreporters. Underreporting of energy intake was highest in men and women who were overweight, had lower family income, or no school education. For men, the most significant variables to predict the ratio of energy intake to estimated basal metabolic. rate (EI : BMRest) were weight status, members of household, alcohol consumption and age, while income and education level were most significant for women.

Objectives: This study examined the nutritional status according to frailty status in the elderly at home. Methods: The participants were a total of 76 elderly at home living in Seo-gu, Gwangju, Korea. The nutritional status and frailty status were analyzed using the Nutrition Quotient for Elderly (NQ-E) and the Korean version of the Fatigue, Resistance, Ambulation, Illnesses and Loss of weight Scale (K-FRAIL), respectively. Results: The distribution of frailty status was robust (17.1%), pre-frailty (38.2%) and frailty (44.7%), and its distribution was significantly different in genders, age groups and the number of medications. The mean NQ-E score was 47.0 for total subjects, indicating a low grade. The scores of balance, diversity and dietary behavior factors were within the low grade, while the score of the moderation factor was within the medium-high grade. According to the frailty status, pre-frailty and frailty showed significantly higher scores for sugar-added beverages intake in the moderation constructs than robust. Robust showed significantly higher scores for the exercise hours and perception level for one's health than pre-frailty and frailty. Conclusions: These results suggest that nutrition status is associated with frailty status. Regular nutrition education and visiting nutrition service should be established to improve the balance and diversity of food intake and improve the dietary behavior of the elderly at home.

Objectives: The purpose of this study was to suggest the strategies for improvement of home-delivered meal services for the elderly, to identify reasons for recipients to get started with the services and to evaluate the attitude, acceptability and adaptation of recipients to the services from the perspective of life context. Methods: The data was collected through face-to-face in-depth interviews with eighteen low-income elderly recipients of home-delivered meals and analyzed using a qualitative research method. Results: The results were deduced as four themes which comprised of long-term vulnerable socioeconomic contexts resulted in entry to the services, conflicting acceptability to the services, passive adaptation to taking the services, and positive practices to cope with supplement free meals or other services. The service participation was initiated because of a combination of prolonged, vulnerable socioeconomic contexts, including poverty and unexpected life events such as diseases, disability, living alone, aging and unemployment. With regard to taking the services, conflicting acceptability was observed: positive aspects including saving living cost and good quality of meals, and negative aspects including lack of a tailored service and feeling of stigma. Although the recipients needed an individualized service, they did not express their needs and demands for the services and they accepted the unavailability as an accustomed, prolonged vulnerable socioeconomic context. With regard to lack of tailored services, either self-solution such as modification of eating patterns or community-based network and services were used. Conclusions: We suggest that a system to concretely identify recipients' attitude, acceptability and adaptation for home-delivered meal services should be developed in the establishment of a tailored nutrition support system for the low-income elderly.
