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.

This study was designed to assess the effect of a meal service for home-staying urban elderly people with low-income on their protein nutrition status and serum lipids. One hundred and eighty three subjects, who had already completed the first nutritional survey were assigned to two groups : meal served(served) and non-meal served (non-served). A meal approximately containing one half of the RDA for energy, protein, calcium and iron was served as lunch everyday to served group. After 6 months of meal service, the second nutritional survey was done and changes of parameters were analyzed with paired t-test. Served females showed significantly increased intake of energy while non-served females showed significantly decreased intakes of energy, protein and fat after 6 months. Served males were observed with significantly higher intake of energy, fat, vitamin A, niacin and ascorbic acid, whereas intake of vitamin A was lower in non-served males. Arm circumference of both served and non-served females were significantly lowered after 6 months. Mean DBP of served males was significantly lower, while SBP of served females was significantly higher after 6 months of meal service. Serum total protein, serum albumin, serum cholesterol and LDL-cholesterol were significantly increased within normal range regardless of gender and meal service. But HDL-cholesterol was significantly higher in only served elderly subjects after 6 months. (Korean J Community Nutrition 1(2) : 228-238, 1996)

This study was conducted to find out residential environment, mood states, ADL(Activity Daily Living) and nursing need of the elderly who live alone. The questionnaire survey was conducted on 154 single household elderly over 65years who live n D-city, Kangwon Province. The data were collected between September 1. 1999 and October 17, 1999 and analyzed by means of SPSS package. The results were as follows; 1. The percentage of the subjects who owned their house was no were than $13\%$., which showed that they still belonged to the economically vulnerable class. As for their residential environment, the average indoor temperature and humidity level were $16.45^{\circ}C\;and\;44.62\%$ respectively during the daytime between September and October, which proved to range within the standard scope. The average indoor illumination level was, however, 43.61 Lux, which showed that their illumination environment was very poor. 2. The average score of their mood states was 3.31. which turned out to be rather low. 3. The mean score of ADL was 1.69, which showed that they didn't have any serious inconveniences in their ordinary lives. 4. The mean score of their nursing need was 275, which proved to be close to the normal level. 5. The higher the room humidity was, the higher their nursing need increased. The higher the degree of illumination level was, the lower the degree of their nursing need was and the higher the level of ADL was. 6. The major factors influencing their moon status were the frequency of their contact with children and room humidity. These two factors could account for $22\%$ of the total mood status. These results suggest that the residential environment should be necessarily considered in the psychological nursing intervention for the elderly who live alone and they should be urgently supported in terms of health policy so that they can maintain the optimum level of illumination during the daytime.

Nutrition factors play an important role in the pathogenesis of osteoporosis. The purpose of this study is to investigate the relationship between nutritional status and bone mineral density of elderly women. Three hundred thirty five elderly women (over 65 years) in Asan were divided into three age groups (group 1, less than 70 y ; group 2, from 70 to 75 y ; group 3, 75 y or more). Total alkaline phosphatase and serum calcium (Ca) were analyzed using spectrophotometric procedure. Data for food and nutrient intakes were obtained by a 24-hour recall method. Bone density was measured by broadband ultrasound attenuation (BUA) using QUS-2. Age differences were tested with the X 2 test for categorical variables and with ANOVA and Tukey's test for continuous variables. Correlation was conducted to test the association between bone density and nutrient intake. The subjects in age groups 1,2 and 3 were $36.7\%$, $32.8\%$ and $30.4\%$, respectively. Height and body weight of the subjects were significantly decreased with age. Average bone density of the subjects in group 3 was lower than the other age groups. Osteoporosis determined by t-score is $17.9\%$ for group 1, $24.5\%$ for group 2 and $55.9\%$ for group 3 (p < 0.001). The serum Ca level of the subjects in group 2 was significantly lower than that of group 1 although mean values in all age groups are within the normal range. Dietary Ca intake, nutrient adequacy ratio (NAR) and index of nutrient quality (INQ) were decreased with age. Bone density was negatively correlated with age (p < 0.001), while body mass index (p < 0.01) was positively related with bone density. Although partial correlation did not reveal the significant correlation of BMD and dietary calcium after controlling for age, since calcium intake was very poor compared to sodium and phosphorous intakes, recommendation of more calcium intake for elderly women especially those over 75 years must be continuously emphasized.

BACKGROUND/OBJECTIVES: The objective of this study was to determine dysphagia risk among community-dwelling elderly people living at home. We also examined the impact of socio-demographic variables on dysphagia risk as well as the relationship between dysphagia risk and dietary characteristics. SUBJECTS/METHODS: The study sample included 568 community-dwelling individuals, aged 65 years and above, who were living independently in their own home in Seoul, Gyeonggi, or Gwangju in South Korea. We used a dysphagia risk assessment scale to screen for dysphagia risk and the Mini nutritional assessment to evaluate the nutritional status. Associations between dysphagia risk and other variables were assessed using logistic regression analysis. RESULTS: Of the 568 subjects, 350 (61.6%) were classified into the dysphagia risk group (DR) and 218 (38.4%) were classified into the normal group (non-DR). Being female (odds ratio (OR) = 1.82, 95% confidence interval (CI) = 1.28-2.59), being 75 years and older (OR = 2.40, 95% CI = 1.69-3.42), having a lower education level (OR = 2.29, 95% CI = 1.33-3.97), and having a lower perceived economic status (OR = 2.18, 95% CI = 1.32-3.60) were more frequently observed with dysphagia risk compared to those who did not have such characteristics. Lowered mastication ability (OR = 14.40, 95% CI = 4.43-46.95), being at risk of malnutrition or malnourished (OR = 2.72, 95% CI = 1.75-4.23), lowered appetite (OR = 3.27, 95% CI = 2.16-4.93), and decreased food intake (OR = 2.95, 95% CI = 1.83-4.78) were observed more frequently in the DR group than in the non-DR group when adjusting for potential confounding factors. CONCLUSIONS: It is necessary to develop and apply integrated programs to improve the dietary habits and nutritional status of elderly individuals at risk for dysphagia, especially for women aged 75 years or older with lower educational and economic levels.

Motor skill learning can be acquired implicitly without consciousness of what is being learned. The purpose of this study was to examine the characteristics of implicit motor learning in young and elderly people using a perceptual-motor task. Forty normal young and elderly subjects participated. A modified version of the Serial Reaction Time Task (SRTT) using six blocks of twelve perceptual motor sequences was administered. The paradigm consisted of the first random sequence block followed by the four patterned blocks and another random block. In each block, the go signal consisted of an asterisk displayed in the one of the four parallel arrayed boxes in the middle of the screen. Subjects were instructed to push the corresponding response buttons as quickly as possible. Young subjects demonstrated shorter reaction times during the consecutive patterned blocks reflecting appropriate learning accomplished. Elderly subjects were able to learn a perceptual-motor task with implicit knowledge, but the performance was lower than that of the young persons. These results indicated that implicit sequence learning is still preserved in elderly adults, but the rate of learning is slower.

This study was conducted to find the differences in food consumption frequency of the middle aged(male 20, female 50) and the elderly(male 15, female 15) living in Chonju in December, 1998 according to food habits, smoking, alcohol drinking and exercising habit, health status, and the levels of nutrition knowledge and attitude store. The foods frequently consumed among the subjects were kimchi(15.4/week), mixed rice(11.5/week), rice(7.6/week), vegetables in soup, jjigae and jorim(5.0/week), mandarins and oranges(5.e/week), and seasoned laver(4.3/week). There were several factors influencing food consumption patterns. These were age, regularity of meal times, the status of smoking, alcohol drinking and exercising, and the level of nutrition attitude. The elderly ate cooked rice more frequently, while the middle aged ate fish, especially blue fishes more frequently. The middle aged who had breakfast regularly ate milk and milk products, legumes and fruits frequently. Those who smoked seemed to eat less cereals and starches and fats, while those who didn't smoke ate more sugars. The alcohol drinking group also ate less fats and the exorcising group ate almost all of food groups frequently. The status of health showed to be related with food consumption patterns. The normal group in hemoglobin ate eggs more frequently than the anemia group and the high risk group in blood pressure ate almost all of food groups more frequently. The high level group for nutrition attitude score chose vegetables, fruits, and milk and milk products more frequently than the other groups. On the other hand, low level group for nutrition attitude score was apt to eat ramyun, ham-sausage, and carbonated beverages more frequently. Therefore, nutrition education to improve the food habits find to change nutrition attitude is necessary to promote health status anti mole attention should be taken to the high risk group in blood pressure to guide proper food and nutrition intakes.

The purpose of this study was to estimate the prevalence of hypertension, and to assess the risk factors associated with hypertension in elderly (over 65 years old) Koreans, using data from the 4th Korean National Health & Nutrition Examination Survey (the 4th KNHANES), 2007~2009. A total of 1,887 participants were analyzed for assessing the risk factors after excluding those who took hypertension medicines or underwent diet therapy (hypertension perceivers). On the other hand, in analyzing prevalence, a total of 3,526 people were analyzed, including hypertension perceivers. Hypertension was more frequently found in female (64.1%) and urban (62.0%) groups compared to male (55.6%) and rural (57.4%) groups. The mean age of the hypertensive group was significantly higher than that of normal group. The mean values of total cholesterol levels were also significantly higher in the hypertensive group, while body weight, waist circumference, fasting blood glucose, hemoglobin, hematocrit, LDL-cholesterol, and HDL-cholesterol were not. Multiple logistic regression showed that smoking was significantly related to the prevalence of hypertension, but alcohol drinking, stress, obesity, hypercholesterolemia, hypertriglyceridemia, diabetes, anemia, and nutrient intakes were not. The results of this study does not support clear relations of hypertension with chronic diseases including obesity, hyperlipidemia, anemia, and diabetes as well as nutrient intakes among a Korean elderly population. A prospective long-term research study is needed to establish the effects of these factors on hypertension.
