Race and ethnicity are important factors which influence the elderIy's residential adjustment behaviors, although it is unclear whether this reflects influences unrelated to race and ethnlcity. Culturally, the norm of family supportoften obseved among various minority ethnic groups is likely to provide flexible family suppof for the elderIy. Economically, the life-long hardship ofminority groups is likely to force them to maintain extended family living arrangements simply to reduce expenses via economies of scale. Thecontroversy about the economic need versus the cultural prescription forextended living arrangements remains unresoIved because it fails to articulatethe meaning of family supports among many disadvantaged groups.This study aims to test previous economic and cultural arguments, byexamining ethnic differences iu the eiderIy's responsiveness to their health andeconomic problems. Two hypotheses about cultural influences on the elderly's resideutiai adjustment are examined. First, do elderly minorities receive famiiysupporis for longer periods when they are poor if economic and health status\ulcorner Second, do elderiy minorities receive family supports more often when their health status declines\ulcorner Using the Longitudinal Suvey on Aging from 1984 to 1990. this study employs Markovian multi-state life tables, and discrete and contonuous competing hazard analyses for the transition in living arrangements. The main results provide substantial evidence against the cultural resource thesis. Elderly minorities experience more frequent transition between living alone and living with relatives than white elderly persons when group differences in the extent of mortality and insititutionalization are controlled. The shorter timf of living alone among elderly monorities stems from their greater likehood of joining relatives as well as greater mortality and attrition rates than elderly whites. Coresidence of elderly whites with their relatives is more likely to occur in response to their needs for health care than of elderly whites. it implies that instability. not flezibility. characterrizes elderly minorities living arrangements.

Purpose: It is reported that most senior people consume a high carbohydrate diet, while a high carbohydrate diet could contribute to the risk of chronic disease. The aim of this study is to determine whether a high carbohydrate diet can increase the risk of chronic disease in elderly Koreans. Methods: Using the 2007-2009 Korean National Health Nutrition Examination Survey data, out of a total of 3,917 individuals aged 65 and above, final 1,535 subjects were analyzed, divided by dietary carbohydrate energy ratio into two groups of moderate carbohydrate ratio (MCR, 55-70%) and excessive carbohydrate ratio (ECR, > 70%). All data were processed after the application of weighted value, using a general linear model or logistic regression. Results: Eighty one percent of elderly Koreans consumed diets with carbohydrate energy ratio above 70%. The ECR group included more female subjects, rural residents, lower income, and lower education level. The ECR group showed lower waist circumference, lower diastolic blood pressure, and lower frequency of consumption of meat and egg, milk, and alcohol. The intake of energy and most nutrients, with the exception of fiber, potassium, vitamin A, and carotene, was lower in the ECR group compared to the MCR group. When analyzed by gender, the ECR group showed lower risk of dyslipidemia in male and obesity in female subjects, even though the ECR group showed low intake of some nutrients. No difference in the risk of hypertension, diabetes, and anemia was observed between the two groups in male or female subjects. Conclusion: This result suggested that a high carbohydrate diet would not be a cause to increase the risk of chronic disease in the elderly. Further study is needed in order to determine an appropriate carbohydrate energy ratio for elderly Koreans to reduce the risk of chronic disease.

The purpose of this study was to identify food consumption patterns of the elderly and factors affecting them to improve their dietary health. Data from 1,172 elderly subjects (over 65 years old) from the fifth Korea National Health and Nutrition Examination Survey (KNHANES V-1) were used in our analysis. Validity and reliability analyses of food consumption frequency allowed the identification of seven factors: fruits, foods for Korean style meal, instant foods, alcohols, carbohydrate-rich snacks, vegetables, and legumes/mixed grains. Food consumption patterns were classified into four groups (according to the food consumption frequency) using cluster analysis. Cluster 4 showed a significantly higher food consumption frequency and Cluster 3 had a relatively high overall food consumption frequency but lower alcohol consumption frequency compared to the other clusters. Cluster 2 was characterized by a generally low food consumption frequency but a significantly higher alcohol consumption frequency. Cluster 1 showed a generally low food consumption frequency; however, the consumption frequency of legumes/mixed grains was higher than Cluster 2. Further analysis showed that the food consumption patterns of the elderly were affected by variables such as gender, age, town, economic status, education level, family type, and frequency of eating out. We conclude that a proper nutritional education program should be conducted to address specific dietary problems for each elderly segment.

Purpose: The aim of this study was to explore the prevalence of major chronic diseases related to daily oral water intake and to identify the physiological parameters related to dehydration in Korean elderly. Methods: The data were collected from the sixth Korea Health and Nutrition Examination Survey (KHANES), which was a nationwide and cross-sectional survey in 2015. We analyzed 1,392 participants using t-test and logistic regression. All participants were divided into the adequate water intake (AWI) group and the non-adequate water intake (NAWI) group based on the dietary reference intakes for Koreans. Results: There was a significant difference in the water intake between the AWI (6.8 cups in a day) and NAWI (2.8 cups) groups (p< .001). There was no statistically significant association between the level of water intake and any of the major chronic diseases. Blood urea nitrogen (BUN) and BUN/Creatinine (Cr) ratio were significantly higher in the NAWI group. Especially, BUN/Cr ratio shows that the NAWI group reached dehydration status. Older age (adjusted odd ratio, OR= 1.07, 95% confidence interval, CI [1.04-1.10]), female gender (adjusted OR= 1.56, 95% CI [1.05-2.33]), lower body mass index (BMI) (adjusted OR = 1.00, 95% CI [0.92-1.00]), higher BUN (adjusted OR = 1.04, 95% CI [1.01-1.08]), and higher urine specific gravity (USG) (adjusted OR= 1.56, 95% CI [1.19-2.05]) were factors associated with the NAWI group. Conclusion: The findings suggest that the level of water intake needs to be considered in relation to age, gender, BMI, BUN, and USG. These are sensitive physiological parameters used for predicting dehydration of the elderly according to their daily oral water intake. It would be helpful to develop strategies to prevent dehydration in elderly individuals and enhance their water intake.

Objectives: This study was conducted to characterize the impact of cognitive function and oral health status on mastication in senior citizens, ${\geq}65$ years of age, using senior centers in the city of Wonju, South Korea. Methods: A cross-sectional study consisting of a simple oral examination and survey questionnaires was performed in 154 individuals. General characteristics, subjective masticatory function, objective masticatory function, cognitive function, and oral health status were collected as variables. Correlation and multiple linear regression analyses were conducted. A p-value of <0.05 was considered to be statistically significant. Results: The subjective masticatory function was scored using the 5-point Likert scale. When subjective masticatory function was analyzed in groups according to cognitive function, the mean subjective masticatory function scores were 4.31, 4.09, and 3.29 in the normal group (cognitive score of ${\geq}16$), suspected dementia group (cognitive score of 1215), and mild dementia group (cognitive score of ${\leq}11$), respectively. Thus, subjective masticatory function decreased along with decreasing cognitive function. When cognitive function, subjective masticatory function, and objective masticatory function were compared with indicators of oral health status (number of functional teeth, oral dryness), subjective masticatory function exhibited a significant positive correlation with objective masticatory function (r=0.635, p<0.01), cognitive function (r=0.292, p<0.01), and total number of functional teeth, including prosthetic appliances (dentures) (r=0.305, p<0.01). According to the regression analysis, age, sex, number of functional teeth, and cognitive function affected subjective masticatory function. Conclusions: The results of this study revealed that age, sex, number of functional teeth, and cognitive function affected subjective masticatory function, whereas oral dryness did not. Therefore, dental professionals must consider subjective masticatory function when providing oral care in senior patients with low cognitive function.

The present study investigated the related variables of cognitive function, subjective cognitive decline and cognitive training effects. The cognitive training was composed of mete-cognitive education and cognitive task performing. Twenty older adults attended for 14 weeks and were tested before and after the training. Results show that their cognitive level was related with age, self-esteem and personality traits. And subjective cognitive decline was related depression, anxiety, personality traits, self-efficacy, self-esteem and subjective age, but it does not reflect objective cognitive impairments. Their cognitive test scores were enhanced after training in MMSE, memory and executive function, and enhanced scores were related with age, subjective cognitive decline, anxiety, self-efficacy, self-esteem, subjective age and personality traits. Findings suggest one's personality and psychological state need to be considered for the effects of cognitive training.

Objectives: With an increase in the population of the elderly in Korea, their nutritional status has become a cause for concern. This study was designed to compare the nutritional intake and health status of the Korean elderly according to their body mass index. Methods: The subjects were 3,274 elderly people aged 65 and above who had participated in the 2016-2018 Korea National Health and Nutrition Examination Survey. The subjects were divided into four groups: underweight, normal, overweight, and obese, based on their BMI. The general characteristics, daily energy, and nutrient intakes, nutrient intakes compared to the recommended nutrient intake, percentage of participants whose nutrient intake was lower than the estimated average requirement (EAR), index of nutrient quality, the mean adequacy ratio (MAR), intakes by food group, and health status of the four groups were compared. Results: Underweight elderly people showed lower energy, lipids, dietary fiber, vitamin C, riboflavin, niacin, phosphorus, sodium, and potassium intake and MAR score (P < 0.001) compared to the normal or obese elderly. The mean protein, riboflavin, niacin, vitamin C, phosphorus, and iron intake of the underweight elderly was lower than the EAR (P < 0.05). Underweight elderly people also had a lower intake of vegetables and fats, oil and sweets food groups than the other groups (P < 0.001). The prevalence of diabetes and dyslipidemia was higher in the obese group, but the percentage of anemia was higher in the underweight group. Conclusions: Underweight elderly people were vulnerable to undernutrition and were at a higher risk of anemia.

Objectives: This case study was conducted to assess the changes in the oral health status of older individuals with hearing and visual impairments through home oral health care based on community care. Methods: The participants were two older adults with hearing and visual impairments. Through home visits, an oral health intervention program, including oral hygiene care and training on strengthening of oral function, was conducted once a week for 5 months. Dental hygienists performed special oral health interventions such as dental plaque control through individual tooth brushing and interdental care, training on strengthening of intraoral and extraoral muscle function, and denture care for the individuals with visual-hearing impairments. Results: The overall periodontal health status and oral muscle function improved in older adults with hearing and visual impairments. In the case of the visually impaired individuals, changes in the oral health status were oral mucosal moisture (30.1 and 37.2 points before and after intervention, respectively), salivary secretion (3.5 and 4.0 cm before and after intervention, respectively), and maximum tongue pressure (20.5 and 26.2 kPa before and after intervention, respectively). Changes in the oral health status of the hearing impaired individuals increased from 28.3 points before the intervention to 38.4 points after the intervention, and the maximum tongue pressure increased from 1.85 kPa to 23.5 kPa after the intervention. Conclusions: Oral health intervention activities contributed to improving the periodontal health and oral function of older adults with hearing and visual impairments. To improve their overall and oral health, it is necessary to prepare measures to activate customized oral health intervention programs.
