It has been proposed that differences in diet between smokers and nonsmokers may partially explain the positive association between cigarette smoking and chronic diseases such as cancer and coronary heart disease. To investigate the potential for this confounding, the authors studied the relation between cigarette smoking and dietary pattern including nutrient intake in 152 Korean elderly people aged 59∼84years. Dietary intake was determined by a 24-hour recall method and a food frequency questionnaire. Male smokers were lighter than nonsmokers and had a lower body mass index(BMI)(p<0.05). But there were no differences in body weight and BMI between female smokers and nonsmokers. Female smokers had lower intakes of energy and carbohydrates than nonsmokers(p<0.05), but in male, smokers and nonsmokers did not show the difference in energy intake. The mean intake of fiber, protein, fat, minerals, and vitamins did not vary significantly by smoking status. However, both male and female smokers consumed fewer fruits than nonsmokers and ate fresh fruits less often than nonsmokers. The total food frequency score which reflect dietary quality of smokers was lower than those of nonsmokers(p<0.05). Male exsmokers' diet were similar to those of smokers, but in female, dietary patterns of exsmokers were similar to those of nonsmokers. These results confirm that elderly smokers have partially different nutrient and food intake patterns from nonsmokers. The decreased ingestion of fruits and less balanced diet by cigarette smokers could contribute to their increased risks of chronic disease compared with those by nonsmokers. The increased ingestion of nutrients and improved nutritional balance in the diet of exsmokers may help to reduce their risks as well.

The purpose of this study was to investigate the relationship among isometric and isokinetic muscle strength, lean body mass(LBM) and bone mineral density(BMD) in the elderly. Eleven males(age, 70.27${\pm}$5.78yr; height, 167.36${\pm}$6.68 cm; weight, 68.34${\pm}$8.23 kg) and thirteen female(age, 69.77${\pm}$4.13yr; height, 152.80${\pm}$4.45 cm; weight, 56.86${\pm}$7.40 kg) participated in this study. In all subjects, LBM and BMD segments was measured by using Dual-energy x-ray absorptiometry(DEXA, Lunar DPS-DM, U.S.A.). Maximum isometric and isokinetic muscle strength of flexion and extension at the knee and elbow, ankle, trunk joints were measured by using an isokinetic dynamometer(CON-TREX(R) Multi Joint Testing Module, Switzerland). The results of this study showed that isometric and isokinetic muscle strength was significantly higher in extension than flexion. In the male and female, hamstring to quadriceps strength ratio(H:Q ratio) was increased as contraction velocity increased. BMD was correlated significantly with trunk extension in the male, but not in the female. LBM was correlated significantly in the male and female with knee extension strength. This study suggests that in the elderly muscle strength training program should put more weight on extensor muscles of the body.

The effect of meal service for home-staying, urban elderly with low income on their mineral status and prevalence of clinical symptoms was evaluated. One hundred. One hundred and eighty three subjects were assigned to meal-served(served) and non-served(non-served)groups. A meal containing approximately one half of the RDA for energy, protein, calcium and iron was served as lunch every day to served group at a welfare center. Dietary, biochemical and clinical data were collected before and after 6 months of meal service and the changes of parameters were analyzed with paired t-test. served female showed significantly increased intake of calcium. The mean hemoglobin, serum iron, TIBC and serum copper of female were significantly increase with meal service. The proportion of anemic female compared to reference data on hemoglobin, hematocrit and serum iron were 45.5$\%$, 29.1$\%$ and 16.4$\%$ respectively, but were lowered to 18.2$\%$, 7.3$\%$, and 5.5$\%$ after 6 months of meal service. served male showed significant increase in MCHC, serum copper, and urinary Na. The urinary Ca/Creatinine, which is often used as an index of bone resorption, was decreased significantly in served group. The decrease in the proportion of served women suffering from edema of ankle and diarrhea was most apparent and less women reported feeling clinical symptoms of dizziness, constipation, difficulty in hearing, and coughing after meal service. The symptoms of benumbness of hands and feet and coughing was lowered most among men after meal service. Clinical symptoms of non-served elderly did not show improvement in feeling clinical symptoms except slightly decreased frequency in coughing of female and buzzing sound in the ears and diarrhea of male.

Insufficient dietary intake of vitamin A is one of the major nutritional problems for elderly adults in some parts of Korea. The objective of this study was to determine the vitamin A nutritional status of elderly adults in Asan, Korea by assessing the dietary intake and serum retinol concentration. Five hundred twenty four subjects (218 male and 306 female) over 65 years were recruited from city of Asan. Each subject was interviewed to assess the intake of vitamin A using a 24hr recall method and data were analysed from computer-aided nutrient analysis program. Blood samples after 12hr fasting were collected for serum retinol concentration and reverse phased HPLC with UV detector used. The results showed that subjects did not consume the sufficient amount of energy (82-85% of Korean RDA for male and 77-79% RDA for female) and vitamin A (59% RDA for male and 50% RDA for female). Range for retinol intake was 0 to $4342\;{\mu}g$ a day while that of beta-carotene was 65 to $31595\;{\mu}g$. Serum retinol concentrations were within a normal range for both male ($80\;{\mu}g/dl$) and female ($67\;{\mu}g/dl$) subjects. Many subjects (n=342) consumed less than 50% RDA of vitamin A. However, if retinol intake was high (> $37\;{\mu}g$), even with less than 50% RDA of vitamin A intake, serum retinol concentration was high ($75\;{\mu}g/dl$). Subjects showed normal serum retinol status even with low vitamin A intake. The results suggested that optimal intake ratio of dietary retinol and carotenoid is important to maintain an appropriate serum retinol concentration.

Background: The elderly population is increasing rapidly worldwide. Muscle mass, usual walking speed (UWS), knee extension strength (KES), hand grip strength (HGS), peak expiratory flow (PEF), and depression is used for sarcopenia diagnosis. All four of these factors (KES, HGS, PEF, and depression) correlated with UWS and also to muscle mass. But, many studies have suggested that no correlation exists between muscle mass and UWS. Objects: This study aimed: 1) to investigate whether muscle mass reduction affected UWS, as mediated by KES, HGS, PEF and depression, and 2) to explored whether significant changes in these mediators varied by the body segment in which muscle mass evaluated in elderly female aged 65-80 years. Methods: A total of 100 female aged 65-80 years were surveyed. Muscle mass was measured by body segment (upper and lower segment), and KES, HGS, PEF, depression, and UWS were also assessed. Median analyses were progressed in IBM SPSS software (ver. 23.0, IBM Co.) using a downloaded INDIRECT macro. Results: The direct effect of the KES and PEF were significant, and the indirect effect of KES and PEF were not significant. Thus, KES and PEF served as full mediators of the effect of muscle mass on UWS. Regardless of bodily region, KES and PEF combined with muscle mass were significant mediators of UWS, with similar indirect effect sizes. Conclusion: KES and PEF are the only mediators regardless of body part. Therefore, mediating the KES and PEF may prevent sarcopenia progression in elderly female. Also, sarcopenia can be readily assessed by evaluating either the upper or lower body; it is not necessary to measure total muscle mass.

Purpose: The purpose of this study was to investigate the health status, nutritional status, and nutrient intakes of Korean female elderly who are members of a local church in Seoul, Korea. Methods: The subjects were 59 female who are aged >65 yr. We investigated the nutritional status of the subjects using anthropometric and biochemical measurements. Interview was conducted to obtain the information regarding the health status. We also obtained dietary intake of these subjects to figure out the nutrient intakes. Results: The mean age of the subject was 74.0 yr old. Based on the WHO standard (obesity, body mass index, BMI ${\qeq}25$), we categorized the subjects to the obese and the non obese groups. The number of subjects in the obese group was 34 (57.6%). The mean Diastolic BP (p=.002), BMI (p<.001), waist circumference (p<.001), hip circumference (p<.001), blood level of transferrin (p=.038), and nutrient intakes of calcium (p=.026), potassium (p=.046), folate (p=.038) and vitamin E (p=.031) were higher in the obese group than in the non obese group. The subjects with hypertension was 67.5%. The presence of hypertension was correlated with BMI (p<.05). The number of subjects with hypercholesterolemia was 17 (28.8%). The level of cholesterol was correlated with BMI (p<.05) and wasit/hip ratio (p<.05). Conclusion: The female elderly in our study had higher prevalence of obesity which is a risk factor for hypertension and hypercholesterolemia. The nutrient intake of high sodium, high cholesterol, and low dietary fiber of these subjects suggests that there is an urgent need to develop an well planned nutritional education program for female elderly.

This study was to performed to assess social factors and physical health status. The subjects of the study were 103 elderly people of age over 85 years living in Ganghwa-gun area. The method of this research was based on the interview-survey with questionnaire. Chi-square test was the main data analysis method. The subject group was composed of 36 males and 67 females, the average age being 91.0 $\pm$ 3.2 years old for the males and 91.1 $\pm$ 3.4 years old for the females. The aged average height and weight were 161.0 $\pm$ 7.9 cm and 54.6 $\pm$ 7.8 kg in males, 141.0 $\pm$ 8.2 cm and 42.2 $\pm$ 7.9 kg in females which were lower than the Korean average standard but the mean BMIs of both male and female showed normal range. Their level of education was lower and they tended to be religious. The aged population might be economically poor. Their level of living standards tended to have been lower-middle and lower class. The mean age of their parents' death were 64.3 $\pm$ 17.2 years in males, 59.0 $\pm$ 14.9 years in females for the father and 70.9 $\pm$ 15.5 years in males, 66.8 $\pm$ 16.6 years in females for the mother. The rate of living together with their family or spouse in the female aged was $83.2\%$ higher than in the male aged. They tended to have engaged in hobbies that require less movement. Of the kinds of hobby, 'TV watching ($47.8\%$ in male and $44.9\%$ in female) was the highest. Ratios of the drinking and the smoking elderly were $30.6\%$, $25.0\%$ in male and $7.5\%$, $18.8\%$ in female but they tended to have never drunken and smoked. Of the subjects, $42.9\%$ spend 8$\~$9 hours for sleeping in male and $35.8\%$ spend 10 hours for sleeping in female. They tended to have not done any particular health behavior. The most common diseases were digestive disease in male, arthritis and hypertension in female. Most elderly males ($47.3\%$) and females ($61.2\%$) had 1$\~$2 diseases.

The purpose of this study was to compare the validity of obese index among body mass index (BMI), waist to hip ratio (WHR), and waist circumference (WC) and to determine which is the best in relation to cardiovascular disease (CVD) risk in Korean elderly more than 65 ages. Data from the 1998 Korean Health and Nutrition Survey were used (n=1017). Anthropometric indices and CVD risk factors were measured, and chi-square test, analysis of variance following duncan's multiple range test, partial correlation analysis, and Receiver Operator Characteristic (ROC) curves were used in the analysis. Anthropometric values were decreased in both male and female when ages were goes up. In female elderly, it specially showed the characteristics of upper body fat and systolic blood pressure risk (p<0.05). Among life style factors the current smokers were prevalent in obese male (p<0.05), but not prevalent in female having obese or upper body fat. Also, person with upper body obesity have more exercise than that of normal group (p<0.01). Mean BMI values of the current smoker was lower than that of normal group in both sexes (p<0.01). Mean BMI value of person with other risk factors were higher than that of normal groups (p<0.05). Among 7 CVD risk factors in partial correlation analysis, WC had the highest correlation coefficient in 5 in male, whereas BMI in 4 in female. In ROC analyses of 12 risk factors and health conditions, the largest area under curve of obese indices for risk factors were WC>WHR>BMI in male and BMI>WHR>WC in female. The optimal cutoff values of each index (BMI : WHR : WC) for one or more risk factors were 19.02 : 0.84 : 71.3 in male and 19.04 : 0.88 : 85.6 in female. In conclusion, Most Korean elderly showed non-obese and abdominal obesity likewise other Asians. Also CVD risk factors were prevalent in Korean elderly within normal limits of obese indices. Therefore the upper body fat indices reflected in the aged whose muscle mass is replaced by fat must be used as an indicator of CVD risk together with BMI. Although WHR was the worst index based on partial correlation analysis and so located between BMI and WC in ROC curve analysis in both sexes, it need to be use with WC to screen the cardiovascular risk group.

The purpose of this study was to examine the influence of long-term care insurance(LTCI) settlement on life satisfaction of female caregivers for the elderly. In September of 2013, we conducted a survey of 300 female subjects over 65 years old living in Jeonju. For empirical verification, ${\chi}^2$, t-test and regression under control of socio-economic variables were applied to determine whether LTCI settlements changed the level of life satisfaction of female caregivers. First, the results showed that caregivers who were not covered by LTCI had higher healthy life satisfaction than those covered with LTCI. Second, life satisfaction of female caregivers is higher when income and education levels are higher. Third, LTCI settlement did not affect five sub factors of caregivers' life satisfaction. The results suggested that LTCI policy should cover not only the insured but also caregivers'physical and mental aspects.

To provide a satisfactory life for the elderly females who are the most impoverished among the elderly social strata, this study is geared towards, and focused on, the exploration on their attitudes towards death. For the purpose of this study, in-depth interviews with females aged 65 and over, who are officially classified as the beneficiary of national fundamental livelihood security, have been conducted. Then, the results from these interviews have been compiled and analyzed through qualitative research methods. As a result of this research, the attitudes of the destitute elderly females towards death are categorized into several themes, such as 'Feeling close to the death through a hard life', 'Positive acceptance of the death', 'Relying on funeral services from government and religious organization', 'Hoping for a death with dignity'. The attitudes of death means to them that 'they can get out of a hard life', and elderly female beneficiaries were positive in their acceptance of this meaning. Those who could obtain funeral services as a part of assistance from government and a religious organization did not feel stressful about their funeral arrangements. However, there were individuals who didn't know if their funeral services would be covered by the government. They were unsure if a funeral service would be held for them, or they would have nobody to hold a funeral for them. Accordingly, they were worried about that. The poor elderly females were unhealthy and indigent, and so, they had death anxiety. Therefore, based on the study results above, some ideas regarding elderly welfare are proposed to enable poor elderly females to face their deaths with dignity.
