The primary goal of the present study was to explore more detailed evidence for the influence of aging and gender effects on the capability of Korean healthy, ears to generate DPOAEs. DPOAEs were examined in series of human subjects, with clinically nonnal hearing, ranging in age from 10 to 65 years. All 60 Koreans were divided into 6 age groups. Each age group included 10 participants, 5 females and 5 males. The gender effects on the difference between the absolute amplitude and noise floor value in DPOAEs did not exist. The difference increased as the frequency increased. The aging effects on the difference between the absolute amplitude and noise floor value in DPOAEs did exist. The difference increased as the frequency increased but orderly age effects could not be found. The principle finding was that, when compared between emissions in young and old ears, DPOAEs accurately tracked the systematic deterioration of high-frequency hearing in aging individuals. Such results support the need to reestablish the criterion for interpretation of DPOAEs in the elderly.

This study was conducted to identify the level of diabetes self-care knowledge, confidence, behavior and quality of life in elderly people with diabetes. The participants were 205 elderly with diabetes who visited a citizen health center located in D city. Korea. The data were collected from April, 20th to August 31th, 2015, and were analyzed by the t-test and ANOVA. The results were as follows; 1) The mean scores for diabetes self-care knowledge, confidence, behavior, and quality of life were 6.99 (2.17), 71.27 (10.21), 62.78 (1.29) and 0.86, respectively. 2) There were significant differences in the self-care behavior according to the education level, duration of diabetes mellitus and subjective health, and the quality of life differeddepending on the level of subjective health(F=35.253, p=0.000). 3) Knowledge of diabetes diet was the lowest among the various aspects of diabetes self-care knowledge. Confidence for exercise was lowest, while confidence for medication and blood sugar check was highest. However, the participants exhibited good medication behavior, whereasthey did not carry out blood glucose checks in their self-care management behavior. The most uncomfortable aspect of the quality of life was found to be pain and discomfort. Based on the results of this study, it is necessary to develop guidelines and methods for dietary education reflecting the dietary habits of Koreans, and to investigatethe reasonsfor thelow performance of theblood glucose check. In addition, customized nursing interventionstaking into consideration the characteristics of elderly with diabetes need to be developed and verified.

The main purposes of this study are to describe the elderly dementia, and to explore characteristics of the elderly dementia among the aged 65 and over in Daegu area. In this study, 1,120 subjects which were 0.6 percent of the population were selected and face-to-face interviews were conducted. The face-to-face interviews were conducted from July 1, 2004 to August 31, 2004. KMMSE was introduced to measure the status of the interviewees' dementia. The findings of this study are as follows: 8.9 percent of respondents turns out to be dementia patients. Among the dementia patients, 52.5 percent are mild dementia patients, 35.0 percent are mid-level symptoms and 12.5 percent are severe symptoms of dementia patients. Cross-tabulation analyses and logistic regression analysis were introduced to explore the demographic, living, and behavioral differentials of the elderly's dementia. According to the logistic regression analysis, it turns out that white educational attainment, participating in the leisure activities for both physical exercise and mental activities, having meals regularly, adequate amount of meals, and high economic status decrease the odds ratio of elder dementia among the elderly who are 65 and above in Daegu area and are statistically significant. On the other hand, age increases the odds ratio of the elder dementia of the elder among Koreans above 65 in Daegu area. Finally, policy implications and some suggestions for the improvement of the elder dementia are introduced and discussed.

Background: As of 2016, average Koreans sleep 7 hours and 42 minutes, the lowest figure among Organization for Economic Cooperation and Development(OECD) countries, and the number of people with sleep disorders reached 561,000. Accordingly, the government has promoted the provision of 'Multiple Sleep Test' to strengthen the diagnosis service for patients with 'sleep disorder' in july 2018. As a result, healthcare costs for patients with sleep disorder is on the rise every year. In this study, we utilized 'Appropriate Sleep' criteria of United States's National Sleep Foundation(NSF) then investigated Korean's sleep pertinence using ｢7th National Health and Nutrition Survey for 2016-2018」 by different occupational type, demographic characteristics, socio-economic characteristics, and health behaviors. Methods: We performed descriptive analysis to examine differences of sleep appropriateness by various sample characteristics. Multivariate logistic regression models were used to examine sleep appropriateness by occupational type and other variables. We also analyzed subgroup models to investigate. Results: As a result, a total of 1,948 (18.37%) study subjects experienced in-appropriate sleep. Results of the Multivariate logistic regression analysis revealed that blue color group had a higher odds ratio (OR) for experiencing in-appropriate sleep (OR=1.179). In addition, the odds ratio of experienced in-appropriate sleep among the elderly aged 70 and over was 2.698, and the odds ratio of the overstressed group was 1.299. Furthermore, sub-group analysis showed that blue color job of female(Or=1.334), high school or below(OR=1.404), divorce/death/separation(OR=2.039), 25%ile-50%lie income group(OR=1.411) more likely experienced in-appropriate sleep. Conclusion: Growing sleep disorder patients and related health care costs are expected. Government should apply detailed 'total periodic sleep disorder management policy' including pre-consultation, examination, diagnosis, treatment, post-consultation, self-management especially to vulnerable population that this study found.

BACKGROUND/OBJECTIVES: Korea is quickly becoming an aged society. Dementia is also becoming a vital public health problem in Korea. Cognitive impairment as a pre-stage of dementia shares most risk factors for dementia. The aim of the present study was to determine associations of serum levels of vitamins A, C, and E with the risk of cognitive impairment among elderly Koreans. SUBJECTS/METHODS: In this cross-sectional study, a total of 230 participants aged 60-79 years from Yangpyeong cohort were included. Cognitive function was assessed by the Korean version of the Mini-Mental State Examination for Dementia Screening. The logistic multivariable regression model was applied to determine the effect of serum vitamins A, C, and E on the risk of cognitive impairment. RESULTS: There was no significant association between the risk of cognitive impairment and serum levels of vitamin A and vitamin C. There was a significant odd ratio when the second tertile group of beta-gamma tocopherol level was compared to the first tertile group [odds ratio (OR) = 0.37, 95% confidence interval (CI) = 0.14-0.98, P for trend = 0.051]. In subgroup analyses, there were significant negative associations between beta-gamma tocopherol level and the risk of cognitive impairment in men (OR = 0.17, 95% CI = 0.03-0.87, P for trend = 0.028), non-drinkers or former drinkers (OR = 0.13, 95% CI = 0.02-0.66, P for trend = 0.025), and non-smokers or former smokers (OR = 0.27, 95% CI = 0.09-0.82, P for trend = 0.017). CONCLUSION: Serum beta-gamma tocopherol levels tended to be inversely associated with the risk of cognitive impairment. Further prospective large-scaled studies are needed to examine this association.

Purpose: We conducted comparative analysis of dietary behavior and food and nutrient intakes of Korean elderly in urban and rural areas using the 2014 Korea National Health and Nutrition Examination Survey (KNHANES). Methods: This study was conducted on 1,239 participants (urban elderly: 867, rural elderly: 372) aged 65 years and over who participated in the health examination and nutrition survey in the 6th 2014 KNHANES. Dietary behaviors, including skipping meals, eating out frequencies, and food and nutrient intakes were analyzed using 24-hour recall data. Analysis of complex sample design data through SPSS 19.0 was used for the analysis. Results: The rate of skipping dinner was higher in urban (6.5%) than in rural elderly (3.6%) (p < 0.05), and the frequency of eating out per week of urban elderly (1.73) was higher than that of rural elderly (1.35) (p < 0.001). The rural elderly consumed a greater amount of grain compared to urban elderly, whereas consumption of water, seaweed food, and dairy products was lower in rural than in urban areas (p < 0.05). The rural elderly consumed significantly less highly unsaturated fatty acids, n-6 fatty acids, phosphorus, iron, vitamin A, carotene, niacin, and vitamin C in comparison with elderly in urban areas. Comparison of the percentages of Dietary Reference Intakes for Koreans (KDRIs) between the two groups showed that intakes of vitamin A and vitamin C were significantly lower in the rural elderly than in urban elderly. Conclusion: The elderly in rural areas showed unbalanced food and nutrient intakes compared to the elderly in urban areas. Therefore, customized nutrition education according to residential areas should be developed and provided to rural elderly to improve their health and nutritional status.

Five hundred and seventy-eight healthy subjects (351 men and 227 women) with a mean age of 44.8 years (45.2 for men, 44.3 for women) participated in this study. The serum concentrations of $\alpha$-tocopherol, \beta$-carotene, $\alpha$-carotene, zeaxanthin + lutein, cryptoxanthin, lycopene and retinol of normal Koreans were measured, and their relation to gender, age, BMI, alcohol consumption, cigarette smoking, and menopausal status were evaluated. The concentrations of $\alpha$-tocopherol, carotenoids and retinol in serum were measured simultaneously by reverse phase HPLC (multi-wavelength, gradient and computerized automatic system). Average serum levels of $\alpha$-tocopherol, \beta$-carotene and retinol were 10.1$\pm$0.41\mu$g/dl, 33.1$\pm$1.24\mu$g/dl, and 82.0$\pm$1.63\mu$g/dl for men and 11.1$\pm$0.74\mu$g/ml, 48.1$\pm$1.60\mu$g/dl and 64.5$\pm$1.96\mu$g/dl for women, respectively, Serum concentrations of $\alpha$-tocopheol \beta$-carotene, $\alpha$-carotene, cryptoxanthin and lycopene appeared to be higher in women than in men. The serum concentrations of zeaxanthin + lutein increased with the increase in age of men and those of $\alpha$-carotene and \beta$-carotene increased with the increase in age of women. For men, current smokers showed significantly lower serum concentrations of \beta$-carotene and $\alpha$-carotene than ex-smokers (p <0.05) . Current drinkers also showed significantly lower serum \beta$-carotene and zeaxanthin + lutein concentrations than ex-drinkers. For women, current smokers showed significantly love. serum concentrations of zeaxanthin+lutein and cryptoxanthin than ex-smokes (p<0.05). Men with BMI$\geq$24 showed significantly lower serum concentrations of \beta$-carotene, $\alpha$-carotene, lycopene and cryptoxanthin than men with BMI < 20. The mean concentrations of $\alpha$-tocopherol, \beta$-carotene, $\alpha$-carotene and lycopene far postmenopausal women were higher than those for premenopausal women (p<0.05). In conclusion, there were obvious differences in serum $\alpha$-tocopherol and carotenoids levels depending on gender, age, cigarette-smoking habits, alcohol consumption, BMI and menopausal status. further studies are required to establish the normal levels of these vitamins for children and the elderly and to elucidate their roles in different disease states.

This study was a pilot test of serious educational game content(named Roly Poly 160) designed to enhance self-care by elderly diabetics. Roly Poly 160 was developed in eight steps (literature review, demand survey and consultation, extraction of serious content using games, development of Roly Poly 160, pretest for users, workshop for health care workers, final completion of Roly Poly 160 and user satisfaction survey of Roly Poly 160). Roly Poly 160 is intuitively structured in three modules (self-management, card games, and quiz games) that can be self-managed by the elderly and is designed based on six principles. First, we constructed an intuitive interface considering the age of users. Second, the menu was selected as the main menu for Koreans and calorie learning was made at the same time. Third, the calories and nutrients (carbohydrate, fat, protein, calcium, sodium) of selected foods are analyzed, and all test data recorded in the questionnaire chart are graphically displayed by year, month and week so that the change trends can be grasped at a glance. Fourth, necessary data were saved and output and used as educational data. Fifth, user data are made compatible and aggregated and up to 100 million members can be registered. Sixth, it is designed to be developed as a mobile app if necessary. Using Roly Poly 160, 119 diabetic patients were diagnosed with diabetes, and the satisfaction score was 4.26 out of 5. These findings indicate that Roly Poly 160 is appropriate as a diabetes self-care tool and suggests that there is a possibility to use it as a program to educate people about diabetes in public health centers, hospitals and clinics.

Background: More than half of cases for advanced non-small-cell lung cancer (NSCLC) occur in elderly patients with a median age at diagnosis of 70 years. The aim of our study was to examine the clinical features and prognostic factors contributing to mortality in elderly patients with advanced NSCLC. Methods: Following a retrospective review of clinical data, 122 patients aged 70 years and over with a histopathological diagnosis of locally advanced (stage IIIB, n=32) and metastatic (stage IV, n=90) NSCLC between 2005 and 2011 were enrolled. Results: The median age was 76 years (interquartile range, [IQR], 72-80 years), and 85 (70%) patients were male. Fifty-seven (46%) patients had never smoked, and 17 (19%) were in a malnourished state with a body mass index (BMI) of <$18.5kg/m^2$. The initial treatments included chemotherapy (40%) and radiotherapy (7%), but 57% of the patients received supportive care only. The 1-year survival rate was 32%, and the 3-year survival rate was 4%, with a median survival duration of 6.2 months (IQR, 2.5-15.3 months). Male gender (hazard ratio [HR], 2.2; 95% confidence interval [CI], 1.3-3.9; p=0.005), low BMI (HR, 2.3; 95% CI, 1.3-3.9; p=0.004), and supportive care only (HR, 1.9; 95% CI, 1.2-2.9; p=0.007) were independent predictors of shorter survival based on a Cox proportional hazards model. Conclusion: Elderly patients with advanced NSCLC had a poor prognosis, particularly male patients, those with a low BMI, and those who received supportive care only.
