Nutrient intakes estimated using a 24-hr recall, a dirt record and a food frequency questionnaire(FFQ) were compared in a group of ninety-four elderly people(21 males, 73 females) in Cheongju, a city in Chung-Buk province. Mean intakes for energy, protein, Ca, p, Na, K thiamin and niacin obtained from the diet record were higher than those from the 24-hr recall. Mean intakes for energy, protein, Ca, P, Na, K thiamin, niacin and vitamin C from the FFQ were higher than those obtained from the 24-hr recall or the diet record. Correlation coefficients between the nutrient intake values from the 24-hr recall and those from the diet record ranged from 0.84 to 0.95 and were significantly correlated(p < 0.001). About 80% of the subjects in the lowest quintile by the 24-hr recall were also in the lowest two quintiles by the diet record. While the percentage fallen into the opposite category ranged from 0% to 15%. For most nutrients, at least 65% of the subjects when classified by the 24-hr recall fell into the same quintile when classified by the diet record, and the mean kappa value was 0.7. About 52% of the subjects in the lowest category by the 24-hr recall fell into the lowest two categories by FFQ. The mean percentage of the subjects in the lowest quintile by the diet record or in the lowest two quintiles by the FFQ was 51%. For most nutrients, at least 24% of each of the subjects when classified by both the 24-hr recall and the diet record fell into the same category when classified by the FFQ. The kappa values between the 24-hr recall or the diet recall and the FFQ were 0.17. These data indicate that in elderly subjects the 24-hr recall can provide very similar information to that obtained from the diet record but the FFQ can not provide good information if the right FFQ method is not used for only elderly subjects.

Multiple physical changes of the larynx and its components occur with age. Vocal pitch, commonly expressed through measures of fundamental frequency (Fo) relate to physical conditions of the larynx. Available data is lacking for the senescent voice, and should be applied to the of changes of elderly speakers' Fo characteristics. The purpose of this study was to investigate the Fo of normal elderly speaker's voice. A total of 406 normal elderly speakers (207 males and 199 females) participated in this experiment. Age ranged from 60 years to 89 years. The subjects were asked to produce sustained corner vowels (/a/ /i/ /u/) three times each and the data were analyzed using the MDVP of CSL. According to the results of this study, the mean Fo from the ages of 60's to 80's shows 143.95Hz(SD 13.94) for men and 185.42Hz (SD 15.29) for women. For men, a significant change is found as a function of age in the Fo (F=16.181, p<.05). A post-hoc Scheffe test revealed significant differences between the Fo data of subjects aged 60's and 70's, 60's and 80's. For women, a significant change is found as a function of age in the Fo (F=49.013, p<.05). A post-hoc $Scheff'{e}$ test revealed significant differences between the Fo data of subjects in their 60's and 70's, 70's and 80's, 60's and 80's. The Fo of men goes up from their 60's to 80's gradually, whereas the Fo of women goes down gradually until their 70's, and after their 70's it again increases. It has been known that diminishing estrogen levels in women in old age may be a factor in lowering Fo, whereas diminishing testosterone levels in men may contribute to a rising Fo. This result may be used as some meaningful guideline and lead the basic data to differentiate between normal aged voice and aged voice disorders.

This study conducted an interview questionnaire survey of 245 old people in some halls for the aged in the Daejeon Metropolitan City from June 1 to 31, 2008. on their attitudes toward and practice items for oral health, resulting in the following findings. 1. In terms of socio-demographic characteristics of the subjects, males females were 48.2% and 51.8% respectively, and in the educational level, no-education, elementary school graduation, middle school graduation, and high school graduation and higher were 27.8%, 33.9%, 26.5%, and 11.8%, respectively, showing the statistically significant difference (p=0.009). 2. In terms of attitudes toward oral health management by oral health care education, regarding questions of use of oral and dental hygiene products (p=0.016), experience in scaling, and whether or not they wear false teeth (p=0.018), a group having received the education rather than a group not having received it showed more positive oral health management attitudes, indicating the statistically significant difference. 3. In daily living inconvenience of acute oral health diseases according to oral health care education, acute oral diseases presents in a group with the education ($2.30{\pm}0.72$) lower than in a group without the education ($2.49{\pm}0.63$), indicating the statistically significant difference(p=0.031). 4. Factors of oral health diseases showed the significant relation with types of health insurance, subjective systemic health status, acute diseases and subjective oral health status (p<0.01), and the explanatory power or the final model was 38%. Accordingly it is thought that there is the indicated need for analyzing and grasping factors related to oral health diseases among the elderly through considering their attitudes toward and practice for oral health, and developing programs of enhancing the oral health of the elderly in order for them to change their attitudes and habits, and also reinforcing oral health care education for the elderly focused on making them perform oral health behaviors in a right way.

In order to supply the reference data to define the quality of life of the rural agricultural elderly population in the simplified steps, the data were collected by personal visits to 232 elder people over 65 (89 males and 143 females) in Sunchang area. The survey was conducted with written questionnaires concerning the quality of life, health-related habits, basic physical functions and cognitive behavior. The prevalence of the degenerative diseases were assessed by anthropometric and biochemical determinations. The averaged overall quality of life represented by EQ-5D index with Nam's model was calculated to be $0.865{\pm}0.1509$, and the percentages of people below the average were 38% (low QOL group) and 62% (high QOL group) were found to be the above the average. Generally, the subjects with male gender, higher educational background, higher self-rated health status, higher social activities were belonged to the high QOL group. The high QOL group had higher scores of daily living activities KADL and IADL, and lower risks in cognitive functions K-MMSE and depression scale GDS. There was no statistically significant correlation between biochemical indexes of blood and cognitive function and EQ-5D scores when the results were adjusted for age and gender. There were significant differences in nutritional assessment determined by the MNA between the high and low QOL groups. The low QOL group showed inferior nutritional status. The rapidly measurable factors of the quality of life of rural elderly were turned out to be physical activity scores and the simplified nutritional status measurement.

Owing to continuous economic growth, an increased standard of living, and improvements to health care in Korea, the life expectancy of Koreans rose from 69.0 years in 1985 to 71.3years in 1990. It continued to rise throughout the 1990s, and, by 2002, had reached 76.5years for the general population and 80.0 years for Korean females. Similarly, the percentage of the Korean population that is 65 years of age or older increased from 3.1 in 1970 to 7.1in 2000, and is expected to reach approximately 14,0 in 2019. Thus, according to this estimate, Korea will have evolved from an "aging society" to an "aged society" in only 19years. In the case of other countries, this same transformation has generally taken 2 to 5times longer. One of the major issues related to Korea's rapidly aging population relates to the health problems of the elderly. According to the 2002 National Health Survey Report, 87,6 percent of the elderly were reported to Have at least one chronic disease. In other words, almost 9out of every 10 elderly persons in Korea were suffering from a chronic illness, This, clearly, places a significant economic burden on Korean society in the form of increased health care Costs. This paper examines the increasing prevalence of chronic diseases within Korea's rapidlv aging population and offers some possible short- and long-term solutions to cope with the increased burden being placed on Korea's health care system. These include the basic services at local health centers for the elderly and the national life-long health promotion programs that aim to correct unhealthy behavior, such as smoking, the excessive use of alcohol, and poor eating and exercise habits.

The purpose of this study was to investigate whether the health status as determined by a self-assessment checklist was related to the nutritional status of elderly Korean women. We interviewed 59 female subjects living in the Daegu area aged over 55 years. Information on their dietary intake on two consecutive days was collected by the 24-hour Recall Method. Their body compositions were measured using a Bio-electrical Impedence Fatness Analyzer. Their zinc status was evaluated according to their dietary zinc intake and urinary zinc excretion in urine samples collected for 24 hours. Their heath status was determined by a NSI Checklist. While 50.9% of the total subjects belonged to a moderate nutritional risk group,23.7% of the subjects were at a high nutritional risk. It appeared that only 25.4% of the subjects were evaluated as being healthy. Therefore, the overall nutritional health status of the elderly females belonged to the moderate nutritional risk group. Except for vitamin C, the average daily nutrient intake of the subjects was below the level of the recommended dietary allowances (RDA) for Koreans. The lower the nutritional health score, the better was their dietary intake of energy (p<.05), protein (p<.001), and zinc (p<.01). A positive relationship between their nutritional health score and body fat ratio was also observed (p<.05). Therefore, we suggest that the NSI Checklist could be used as a practical screening tool at the beginning of nutritional surveillance of the elderly in the community.

The purpose of this study was to evaluate the relationship between taste perceptions and risk factors for health of Korean elderly living in rural areas. Recognition thresholds for four basic tastes, drug consumption, BMI, fasting blood glucose, serum total cholesterol, serum triglyceride, systolic blood pressure, and diastolic blood pressure were assessed in 176 males and 312 females aged between 50 and 88 years. For the recognition threshold of the four basic tastes, alcohol drinking did not influence their sensitivities, but the alcohol drinking group preferred a higher pleasant concentration of NaCl than did the non-alcohol drinking group. However, smoking significantly decreased sensitivities of the four basic tastes. For the pleasant concentration of NaCl, the smoking group tended to prefer a higher concentration than the non-smoking group. Drug consumption, fasting blood glucose, serum total cholesterol, and serum triglycerides did not have a significant correlation to the sensitivity of the four basic tastes and preference of salty solution. Systolic blood pressure and diastolic blood pressure may have been positively correlated with the pleasant concentration of NaCl but did not correlate with the recognition thresholds of NaCl and sucrose. Further, systolic blood pressure was negatively correlated with the recognition thresholds of caffeine, whereas diastolic blood pressure was negatively correlated with the recognition thresholds of caffeine and citric acid. The finding that the risk factors for health correlated with taste perception has diagnostic and practical implications for health promotion for the elderly.

Elderly with dementia in geriatric hospitals (EDGH) are highly dependent on hospital meals. This study evaluated the foodservices satisfaction and food preference of the EDGH. The survey was conducted on 104 elderly with dementia (21 males and 83 females) in 4 geriatric hospitals in Seoul and Incheon in November, 2016. Data were collected from interviews using a questionnaire that consisted of 6 questions for foodservice satisfaction and 24 questions (10 categories) for food preference. The data were analyzed using SPSS ver. 20.0. The satisfaction with taste, saltiness, texture, and variety in foodservices was good, but the satisfaction with the amount was not, and the reason for leaving food was its large serving size. The subjects preferred soft boiled rice, noodles, porridges, meats, fish, seafood, vegetables, and fruits. Among them, they preferred more janchiguksu, red bean porridge, beef, croaker, oyster, spinach, and banana. Regarding the cooking methods, they preferred soup, grill, and boiling, but not frying. The also preferred Chinese cabbage kimchi, but they did not prefer hard kkakdugi. They did not prefer milk because of diarrhea, but they preferred yogurt. Therefore, to provide a satisfying meal for EDGH, it is necessary to develop a friendly diet considering their food preferences.

The purpose of this study was to investigate the effects of a nutrition education and personalized lunch service program in a senior welfare center. A total of 30 elderly (14 males, 16 females) aged 62~89 years participated in this study. Nutrition education lessons (2 hour/lesson/week) were provided for 4 weeks. Also, ten weeks from week 3rd to week 12th, personalized lunch providing 1/3 personal needed energy was served 5 times for a week. After the nutrition intervention program, we compared anthropometric characteristics, blood biochemical characteristics, nutrition knowledge, dietary attitude and dietary intake using 24 hr recall with those before the intervention. The body weight (p < 0.001) and body mass index (BMI) (p < 0.001) were decreased. There were significant increases in score of nutrition knowledge (p < 0.01) and consumption of milk & milk products for snacks. There was a positive effect on fasting blood sugar (FBS) showing significant decreases in portion of impaired fasting glucose and diabetes mellitus (p < 0.05). Also, serum triglyceride (TG) was significantly decreased (p < 0.05). In evaluation of nutrient intake by Dietary Reference Intakes for Koreans (KDRIs), riboflavin (p < 0.01), vitamin C (p < 0.001), calcium (p < 0.05) were positively improved. The index of nutritional quality (INQ) and intakes of vitamin C (p < 0.001), riboflavin (p < 0.05), Ca (p < 0.01) and Fe (p < 0.05) were increased. In conclusion, this nutrition education and lunch service program providing 1/3 personal needed energy can be used to develop and implement a tailored nutritional intervention programs in the setting of a community senior welfare center to improve health and nutritional status of Korean elderly.
