Objectives: This study investigated the gender and age differential effect of major chronic diseases on activity of daily living (ADL) disability. Methods: Surveyfreq and Surveylogistic regression analyses were employed on the 2005 Korean National Health and Nutrition Examination Survey (KNHANES) with a sample of 3,609 persons aged 65 - 89. Results: After adjusting for potential covariates, stroke, among elderly men more so than women, had a 2-3 times greater odds of engendering ADL disability in the 65-69 (p < 0.05) and 70-79 age groups (p < 0.01). In comparison to elderly women, cancer, diabetes, and incontinence in elderly men was associated with a higher risk of ADL disability in the 70 - 79 age group (p < 0.05), and this association was also observed for pulmonary disease in the 80-89 age group. Among elderly women, however, a significant association between incontinence and ADL disability was identified in all three age groups. In addition, this association was found in pulmonary disease and diabetes in elderly women aged 70 - 79 years. Significant gender differences were observed in the association between stroke in the 60 - 79 age group and cancer in the 70 - 79 age group. Conclusions: Age and gender differences were observed in the effect of chronic diseases on ADL disability.

The present study was aimed to investigated whether there are age-and sex-related differences in serum levels of lipid peroxides, retinol , and $\alpha$-tocopherol in Korean adults. The subjects were 441 persons , including 268 men and 173 women. Those of each sex were divided into four age group : 20-29, 30-39, 40-49 and 50-65 years, and their lifestyles and serum levels were compared . Men smoked and drank less as age increased , but 99.9% of women of did not smoke and only 11% drank more than once a month. Lipid peroxides of males increased gradually with age, while those of females showed greater levels in the 50-65 years group thon younger groups. Lipid peroxides, retinol and $\alpha$-tocopherol concentrations, which were adjusted for age, were significantly higher in males than in females. Lipid peroxide levels adjusted for total lipid were positively correlated with age in males than in females. Serum levels of $\alpha$-tocopherol adjusted for total lipid were positively correlated with age both in males and in females , while retinol was neither. The results indicate that serum levels of lipid peroxides, retinol , and $\alpha$-tocopherol are affected by age and that the response could be different between males and females.

This study investigated the age dependencies in ambient air pollution-associated asthma hospitalization from 2003 to 2005 in Seoul. For all ages and the age groups of 0-14, 15-64, and 65+years, the Generalized Additive Model (GAM) was used to estimate the relative risks of daily asthma hospitalization associated with changes in particulate matter and ozone. The time-trends, seasonal variances, day effects, temperature, humidity, and pressure at sea level were controlled in the models. Significant associations were observed between asthma hospitalization and the levels of $PM_{10}$ and $O_3$. The relative risks (RRs) of asthma hospitalization for every 10 unit increases in $PM_{10}({\mu}g/m^3)$ and $O_3$(ppb) were 1.008 (95% CI 1.005-1.012), and 1.012 (95% CI 1.003-1.020), respectively. Evaluated over $10\;{\mu}g/m^3$ increase in $PM_{10}$, we found the relative risks of asthma hospitalization to be 1.009 (95% CI 1.004-1.014) in 0-14 age group, and 1.015 (95% CI 1.008-1.022) in 65+ age group. Considering 10 ppb increase in $O_3$, those were 1.014 (95% CI 1.003-1.024) in 0-14 age group, and 1.025 (95% CI 1.009-1.041) in 65+ age group. It was concluded that current levels of ambient air pollution in Seoul make a significant contribution to the variation in daily asthma hospitalization. Further reduction in air pollution is necessary to protect the health of the community, especially that of the higher risky groups including children and elderly population.

This study was analyze through the reports which published on the subject matter of Su Dong-Myun from year of 1972-1993, and analysis of data in 1994 was performed with medical records on the health subcenter by PC-SAS program. The result are as follows: The number of population in Su-Dong Myun(study area) was 5,707 in 1995, 4,641 in 1985 and 5,424 in 1975. In the composition rate of population "0-14" of age group only showed markedly decreasing tendancy from 42.8% in 1975 to 19.1% in 1995. However, "65 and over" showed markedly increasing tendancy from 5.7% in 1975 to 9.8% in 1995. Annual utilization rate showed rapidly increasing tendency from year of 1972 to 1978, such as 314 per showed rapidly decreasing tendency, such as 708 in 1981, 485 in 1984, 272 in 1987, 309 in 190 and in 1993. In the annual age-specific utilization rate, the age group of "0-14" showed the highest rate of 621 per thousand population in 1975, 1159 in 1980, 1021 in 1985 and 538 in 1990. However the age group of "65 and over" showed the highest rate of 481 in 1994. Age specific annual utilization rate showed markedly decreasing tendency in the age group of "0-14" and "15-44", however showed slightly decreasing tendency or same level in the group of "45-64" and "65 and over" from year of 1980 to 1994. In the age specific utilization rate, the lower down the age was, the higher tendency the rate showed, such as 621 per 1,000 population in "0-14" of the age group, 543 in "15-44", 406 in "45-64" and 294 in "65 and over" in 1975. However, the higher up the age was, the higher tendency the rate showed in 1980, 1985 and 1994, except "0-14" of age group. The 5 major diseases were disease of Respiratory system, Gastrointestinal system, Skin and Subcutaneous tissue, Accidents, Poisoning and Violence and Nervous system and Sense organ, in 1975, 1980 and 1985. However, in 1990 and 1994, the 5 major disease were disease of Respiratory system, Gastrointestinal system. Skin and Subcutaneous tissue, Musculoskeletal system and, Connective tissue and Circulatory system. In Composition rate of patient in Su Dong-Myun Health Subcenter by Charged Medical Fee, medical insurance showed almost all the highest rate of 93.9% in year of 1994 and C.H.D.A. of 100% in 1975. Proportion of insurance showed increasing tendency such as 6.6% in 1980, 21.3% in 1985, 69.0% in 1990 and relatively C.H.D.A. showed decreasing tendency.

Korea does not have a certain criteria on the respiratory ability and phonation of the normal aged, and also has no clear standard to examine the boundaries of geriatric diseases. This study analyzed the characteristics in respiration and phonation of the aged in normal healthy elderly from diverse angles with different variables. Thirty-three participants in total, seven males and eight females in the age group 55-64 participated in the study. Seven males and eleven females in the age group 65-74 were selected for the respiration and phonation experiments, and 10 different variables such as FVC, $FEV_1$, $FEV_1$/FVC, MPT, MFR, Psub, f0, jitter, shimmer and NHR were comparatively analyzed for each group of different age and gender. To see the difference in respiration and phonation by age and gender, the study conducted a two-way ANOVA. First, from the result of the analysis on respiratory ability, FVC of male appeared to be significantly greater than female. In both age groups of 55-64 and 65-74, male displayed greater FVC than female did. Second, as for $FEV_1$, $FEV_1$/FVC, the age group of 55-64 showed greater values than the values measured in the age group of 65-74. Third, MFR showed a significant difference by gender. In both age groups, male showed significantly higher MFR than female. Fourth, for different gender, a significant difference in MFR was observed. In both age groups of 55-64 and 65-74, male exhibited higher MFR than female. This study has a clinical implication in that it analyzed the criteria on respiration and phonation in normal healthy elderly according to gender and age. The normal aged showed a difference in their respiratory and phonatory functions by age and gender, it was closely related to the decline of pulmonary function due to the physical aging and the weak respiration coming from weakness of respiratory muscles. Also, the physical differences in height, weight, and the muscles in laryngeal and respiratory system between males and females had an influence on the performance. These results from this study might be a helpful guideline for the clinical criterion in the future.

This study is intended to investigate medication compliance and polypharmacy of the diabetic patients by age group in order to determine the major factors that influence their compliance. 198 ambulatory diabetic patients were interviewed, and the sample was divided into three groups based on the age: Young age group under 55, Borderline age group between 55 - 65, Old age group over 65. According to the study results, medication compliance for the old age group was 72.6% whereas 85.1% for the young age group. Medication compliance significantly decreased as the age of the patients increased. Also the degree of polypharmacy, the rate which patients take more than 6 prescription drugs, was 45.9% for the old group, whereas 31.2% for the young group. As the most important factor of polypharmacy, the number of doctors was statistically significant. With regard to prescription factors related to medication compliance, the amount of prescribed medication is statistically significant between the compliance group and non-compliance group. In addition, the amount of information provided to patients by pharmacists was determined to be a very significant factor. Also the level of ease in understanding the medication instructions varied significantly between the compliance group and the non-compliance group. In light of the empirical data and results for the diabetic patients, it is necessary to develop and implement various programs to improve medication compliance and to decrease the level of polypharmacy among the elderly, or "old", diabetic patients. patients.

A dietary survey was conducted using 24-hour recall method in 80 male elementary school children, 83 high school students, 87 adults and 98 elderly people over 65 years of age to discuss food and nutrient intakes among different age groups. In observing food intake by age groups, the percentage of plant foods to total food intake was significantly higher in the elderly than other groups and that of animal foods was the highest in the children. The children consumed significantly higher amounts of milk and dairy products. Carbohydrate energy percent in the elderly people was 68.0%, significantly higher than other age groups. All age groups consumed Ca below Korean RDA and especially, 65.1% of the adolescents and 68.4% of the elderly consumed below 75% of RDA. Nutrient adequacy ratio (NAR) of most nutrients was lowest in the elderly. Mean adequacy ratio (MAR), an index of overall dietary quality, was 0.94 for the children, 0.84 for the adolescents, 0.84 for the adults, and 0.73 for the elderly. The above results suggest that food and nutrient intakes have been differently affected with advancing age, and overall dietary quality of the elderly people is lower than that of other age groups.

The main purpose of this research is to analyze the variety of self-integration in accordance with the age of the elderly citizens and to verify the interactive effects of age groups and demographical characteristics on self-integration. For the purpose of this research, group of 603 elderly people who reside in Busan and are aged more than 65 were selected as participants. In this research, the elderly citizens were categorized into three age groups namely 65-74, 75-84, and above 85 years. From the results of the research we found out the following results: There were differences in self-integration across the various age groups; the age groups and the level of education had interactive effects on each other; there were differences in self-integration according to the level of education, marital status, type of co-living with children, economic status, and health status. The research showed significance in analyzing, positively the fact that public services which are designed for elder citizens need to be provided discriminatively and they should be suited for the various age groups.

Background: Factors associated with the prognosis of patients with small cell lung cancer (SCLC) is relatively unknown, than of those with non-small cell lung cancer. This study was undertaken to identify the prognostic factors of SCLC. Methods: The medical records of 333 patients diagnosed with SCLC at tertiary hospital from January 1, 2008, to December 31, 2012 were retrospectively reviewed. Patients were categorized by age (${\leq}65$ years vs. >65 years) and by extent of disease (limited disease [LD] vs extensive disease [ED]). Overall survival and progression free survival rates were determined. Factors associated with prognosis were calculated using Cox's proportional hazard regression model. Results: Most baseline characteristics were similar in the LD and ED groups. Eastern Cooperative Oncology Group (ECOG) performance status (PS), first chemotherapy regimen, and prophylactic cranial irradiation (PCI) differed significantly in patients with LD and ED. Mean ECOG PS was significantly lower (p<0.001), first-line chemotherapy with etoposide-cisplatin was more frequent than with etoposide-carboplatin (p<0.001), and PCI was performed more frequently (p=0.019) in LD-SCLC than in ED-SCLC. Prognosis in the LD group was better in younger (${\leq}65$ years) than in older (>65 years) patients, but prognosis in the ED group was unrelated to age. Conclusion: This study showed that overall survival (OS) was significantly improved in younger than in older patients with LD-SCLC. Univariate and multivariate analyses showed that age, PCI and the sum of cycles were significant predictors of OS in patients with LD-SCLC. However, prognosis in the ED group was unrelated to age.

Objectives: We examined the trends in prevalence, awareness, treatment, and control of hypertension in Korea as a basis for improving hypertension control programs. Methods: 12 598 participants of the Korean National Health and Nutrition Examination Survey were included in this study. Weighted linear regression to test time trends from 2007 to 2011 was performed. Results: The prevalence of hypertension was 20.7% in 2007, 29.4% in 2009, and 26.2% in 2011. Awareness of hypertension was 64.8% in 2007 and 61.1% in 2011. Awareness in those aged 65 and over was greater than in younger groups (age 19 to 44 and 45 to 64; p<0.001). The treatment rates were 58.4% in 2007 and 56.8% in 2011. The treatment rate was greater for those 65 and over than for younger age groups (p<0.001). The percentage of controlled hypertension was 37.6% in 2011. The percentage of controlled hypertension in those 65 and over was higher than in younger age groups (p<0.001). The treatment-control rates were 65.9% in 2007 and 67.7% in 2011. The prevalence of hypertension was higher in the males (p<0.001), while the awareness (p<0.001), treatment (p<0.001), and control (p<0.001) rates were higher in the females. Conclusions: The prevalence of hypertension was increasing and the hypertension awareness, treatment, and control rates were low in younger age groups and males.
