Populations both in the US and worldwide are aging. It is projected that by the year 2030 the population of Americans over 65 will increase to 70 million, more than twice their number in 1998. About one-third of elderly over the age of 65 have debilitating chronic health conditions that greatly impede their activities. Age-associated chronic diseases are believed to be associated with free radicals and the imbalance in antioxidant and oxidative stress contributes to development of several chronic health conditions. Diet and nutrients can have great impact in the health status of elderly. Several factors may contributor to the inadequate consumption of nutrients in elderly, including an inability to chew food adequately, polypharmacy, living along and limited income. Low intake of energy and several micronutrients are common among the elderly. Although overt deficiency of nutrients among the elderly is not common. a recent study showed that while elderly consume more fat, the total energy intake is low among the elderly. Inadequate intake of antioxidant nutrients such as vitamin E in elderly may contribute to the development of chronic health problems. Intake of higher than normal RDA levels of vitamin E for long periods of time has been shown to reduce the risk of many degenerative diseases, such as cardiovascular diseases(CVD) and cancer, and improve immune response in elderly. High intake of other antioxidants is also associated with reduced risk chronic diseases. Dietary antioxidants are abundant in fruits and vegetables. However, due to variety of factors, the elderly may not be able to receive these and other micronutrients through diet. Therefore, supplemental intake of micronutrients in the form of multi vitamins/minerals and/or specific micronutrients is a more practical approach to the maintenance of health status in the elderly.

Objectives: This study assessed the accuracy of the 24-hour diet recall method for estimating the energy intake of elderly men using the doubly labeled water as a reference method. Methods: Seventeen subjects (mean age $72.5{\pm}3.9years$), who maintained the same body weight during the two weeks study period, were included in this study. Three 24-hour diet recalls (two weekdays and one weekend) were obtained over a 14 day period to estimate the mean energy intake. The total energy expenditure was measured over the same 14 days using the doubly labeled water method. The total energy intake and total energy expenditure were compared by paired t-test. Results: The total energy intake from the 24-hour diet recalls method was $2536.7{\pm}350.6kcal/day$, and the total energy expenditure from the doubly labeled water method was $2659.8{\pm}306.8kcal/day$. The total energy intake was slightly under-reported by $-123.2{\pm}260.8kcal/day$ (-4.4%). On the other hand, no significant difference was observed between the total energy intake and total energy expenditure of the subjects (p=0.069). The percentage of accurate predictions was 64.7%. The correlation between the total energy intake and total energy expenditure was statistically significant (r=0.697, p<0.005). Conclusions: The present study supports the use of the 24-hour diet recall method to estimate the mean energy intake in elderly men group. More studies are needed to assess the validity of 24-hour diet recall method in other population groups, including elderly women, adults and children.

Purpose: This study was aimed to investigate the effects of the nutritional intervention program including DASH diet education and calcium/vitamin D supplements in Korean elderly women. Methods: This was a quasi-experimental study employing non-equivalent control group pretest-posttest design. The experimental group (n=26) was given DASH diet education and supplements (calcium 1200mg and vitamin 800 IU) while the control group (n=16) was given only general health consults. After the interventions, differences were analyzed in nutrient intake, bone turnover markers and bone mineral density between the two groups. Results: After one year, bone mineral density was found reduced in both groups, but showed higher levels (p=.003) in the experimental group than the control group. After research, nutrient intakes of participants improved generally, yet there was no significant difference between the two groups. The experimental group was divided into subgroups after interventions according to the level of calcium intake, and bone density and bone markers were compared between the subgroups. In a subgroup whose calcium intake was in the normal range, bone mineral density was significantly high (p=.002) while CTx and osteocalcin were significantly low (p=.003, p=.006, respectively). Conclusion: This study is significant in that it provided a nutritional intervention program for one year to elderly women who are susceptible to osteoporosis and severely low in dietary calcium intake and it proved to be effective.

It has been proposed that differences in diet between smokers and nonsmokers may partially explain the positive association between cigarette smoking and chronic diseases such as cancer and coronary heart disease. To investigate the potential for this confounding, the authors studied the relation between cigarette smoking and dietary pattern including nutrient intake in 152 Korean elderly people aged 59∼84years. Dietary intake was determined by a 24-hour recall method and a food frequency questionnaire. Male smokers were lighter than nonsmokers and had a lower body mass index(BMI)(p<0.05). But there were no differences in body weight and BMI between female smokers and nonsmokers. Female smokers had lower intakes of energy and carbohydrates than nonsmokers(p<0.05), but in male, smokers and nonsmokers did not show the difference in energy intake. The mean intake of fiber, protein, fat, minerals, and vitamins did not vary significantly by smoking status. However, both male and female smokers consumed fewer fruits than nonsmokers and ate fresh fruits less often than nonsmokers. The total food frequency score which reflect dietary quality of smokers was lower than those of nonsmokers(p<0.05). Male exsmokers' diet were similar to those of smokers, but in female, dietary patterns of exsmokers were similar to those of nonsmokers. These results confirm that elderly smokers have partially different nutrient and food intake patterns from nonsmokers. The decreased ingestion of fruits and less balanced diet by cigarette smokers could contribute to their increased risks of chronic disease compared with those by nonsmokers. The increased ingestion of nutrients and improved nutritional balance in the diet of exsmokers may help to reduce their risks as well.

This study was designed to assess diet and health-related factors of older adults in Korea. Subjects females were 2,660 adults aged 50 and over living in Korea. Males were 847 persons and were 1813 persons. The mean weight and height for males and females were 63.8 $\pm$ 0.3kg / 164.0 $\pm$ 0.2cm and 57.0 $\pm$ 0.2kg /150.6 $\pm$ 0.1cm respectively. BMI (body mass index), body fat, and percent fat were significantly greater in females than in males. The muscle mass and body water were significantly greater in males than in females. Twenty-one percent of total subjects lived alone and 26% with spouse only. Most of the subject's self-reported income was in middle level (65%) or low level (24%). Proportion of subjects who answered 'very poor' or 'poor' on perceived health status was higher in older group. The 50-64 years old group was facing more stress than 65yr and over group. Among male subjects,38.4% were current-smokers and 22.0% were ex-smokers. But only 6.5% of female subjects were current-smokers. Males turned out to have better dietary habits-meal frequency per day, mealtime regularity, regular meal size and balanced eating-than females (p < 0.001). This study revealed that the diet and health-related factors affect nutritional status and chronic diseases of the elderly. For better management and evaluation of health status of the elderly, more effective nutritional assessment tools should be developed.

In this study, we compared diet related attributes such as food taste preference, food consumption frequency and nutrition intake between elderly residents in their 80's of areas in Jeollanam-do that are well known for longevity and those of a part of Seoul. Structured in-depth interviews were conducted by trained interviewers on 125 consented subjects (67 Jeonnam and 58 Seoul). Differences of groups were tested using Chi-square tests for nominal or ordinal data and t-tests and ANOVA tests for ratio data. The elderly from Jeonnam tended to sleep longer, express emotion more freely, and interact with others more often than those from Seoul. The elderly tended to prefer sweet or salty tastes, which might be highly related to serious health problems. The most frequently consumed foods were napa cabbage kimchi (2.19 times/day) and multigrain rice (1.99 times/day). Elderly from Jeonnam tended to consume garlic, milk, beans and roasted barley/corn teas less often; whereas, they consumed porridge, dried radish greens, potato, fermented fish, dried fish, pork rib, pork belly, soybean paste soup, soybean paste/Ssamjang, other kimchis, pickled vegetables, snacks, cookies, and green/black teas more often than elderly residents from Seoul. Differences in nutrition intake between the regions were greater than differences between the perceived levels of household economic status. NAR and INQ for folate were lower among elderly from Jeonnam than those from Seoul, while those for protein, vitamin C, niacin, vitamin $B_6$ were higher. The study results indicated that elderly from Jeonnam engaged in a more diverse diet than the elderly from Seoul.

Purpose: This study was conducted to investigate the correlation between degrees of health promotion behaviors and life satisfaction and effects of health promotion behaviors on life satisfaction in rural elderly women living alone. Methods: A descriptive correlation study was conducted with 189 rural elderly women living alone aged 65 or older in four senior counties in Jeollanam-do. Descriptive statistics, t-test, ANOVA, $Scheff{\acute{e}}$ test, Pearson's correlation, and multiple regression. Results: The subjects' health promotion behaviors and life satisfaction were significantly positive. Among the factors influencing the subjects' life satisfaction, nutrition and diet showed the greatest positive effects, followed by exercise and activity, and drinking and smoking. Among them, drinking and smoking had significantly negative influence. Conclusion: Among the health promotion behaviors that influenced life satisfaction, nutrition and diet, exercise and activity, and drinking and smoking were most significant factors. Therefore, this study provided basic data for improving the life satisfaction among rural elderly women living alone.

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.

Purpose: This study was to evaluate the nutritional status of low-income elders in urban areas and factors affecting their nutritional risk. Methods: A cross-sectional analysis was conducted. The subjects were 300 elders selected from home visiting clients of DongJack Public Health Center. Data were collected using a questionnaire containing questions on socio-demographic characteristics. health behavior and disease. dietary pattern. Nutritional Screening Initiative. Geriatric Depression Scale and Barthel Index for ADL. Collected data were analyzed through descriptive statistics. $X^2-test$ and multiple regression analysis using SPSS. Results: Of the subjects, 63% had high nutritional risk, 21.3% moderate nutritional risk, and 15.7% good nutritional risk. NSI score was significantly different according to economic status, subjective health condition, medication, dental health, depression. regularity of diet and meal with family. Multiple regression analysis revealed that depression, subjective health condition, dental health and regularity of diet and meal with family explain 38.1% of nutritional risk. Conclusion: It is necessary to evaluate nutrition status and to control nutritional risk factors such as depression, dental health, regularity of diet and meal with family for improving the health of the low-income elderly.

The purpose of the study was to examine nutritional management and nutritional care demands of home-visit care service and the nutritional status of serviced elderly. The survey was carried out from $5^{th}$ to $21^{st}$ of January, 2011 among 37 In-Home Service institutions. The number of elderly surveyed by 143 care helpers was 281. Analysis was performed for 203 subjects (male: 44, female: 159). The age distribution was from 50 to 99 years. The grading by long-term care insuranceshowed 18,2% on level 1 and 2, and 81.8% on level 3. For the disease treatment, the proportion of implementing diet treatment turned out to be very low. The proportion of subjects living with their children was 45.3%, and living alone was 29.1%. The proportion of home-visit care among types of In-Home Service was 70%. Subjects who needed additional necessary diet management service turned out to be 40.9%. Diet management was the most necessary services from all levels. MNA (specifiy MNA) scores were significantly (p < 0.001) associated with BMI, mid-arm circumference (MAC), calf circumference (CC), intake problems, and weight loss during the last 3 months. For studied elderly, 45.3% were malnourished, and 46.8% were at the risk of malnutrition by MNA score. Based on the result of this survey, the nutritional care was not systematic on the In-Home Service. Prevention and management of the disease was much better than the treatment to improve the quality of life. We conclude that nutrition management is necessary for the elderly. To improve nutritional status of elderly in home care services, systematic nutrition management should be implemented.
