The MRI (magnetic resonance imaging) volumetric analysis of the brain was performed in 59 healthy elderly Koreans (aged 62-76 years; 34 male, 25 female) to investigate whether the previously reported significant correlations between body height and brain volumes in the young aged Koreans (20's) still exist in the old aged Koreans (60's and 70's). Unlike previously reported significant correlations in the young aged Koreans, neither the correlation between whole brain volume and body height in male nor the correlation between cerebellar volume and body height in female show any significance in the old aged Koreans. The significant correlation between body height and whole brain volume was still observed when both male and female data were combined (r=0.27, P<0.05), but the correlation coef-ficient and the level of significance markedly decreased from those of previously reported Korean youth data (r=0.67, P<0.01). Simple linear regression analysis shows decrease of explanatory power of height (measured in $r^2$) from 44% in the youth group to 7% in the old age group on the variance of whole brain volume. Multiple linear regression analysis shows that age and sex, rather than height, are major explanatory variables for whole brain volume in the old aged Koreans. The loss of correlations in the aged group is suspected to be mainly due to age related brain volume changes.

Purpose: Number of the old-old elderly is rapidly increasing in Korea, but it is unclear whether there are differences between old-old and young-old elderly in nutritional status, nutrient intakes and health status. The gender differences in Korean elderly in these conditions also remains unknown. This study, therefore, investigated gender-associated differences in nutritional, health status and nutrient intakes and how they are related among young-old and old-old homebound elderly. Methods: Two hundred and eighty elderly who were attending a local elderly welfare center were recruited. Evaluation included demographic, nutritional and health status related data, nutritional intakes, and life style related factors including physical activity. Results: Of the 280 subjects, old-old were 147 (52.5%) and young-old were 133 (47.5%). Male old-old elderly had more often abdominal obesity than female old-old, but male old-old more often had malnutrition than female old-old. There were few differences in nutrient intakes between old-old male elderly and female elderly after energy intakes were controlled. Male old-old more often had less intake of beta carotene and Vitamin A than female old-old. On the other hand, male old-old elderly more often had hypercholesterolemia and hypertension than male young-old. Conclusion: Male old-old may be at a greater health and nutritional risk than female old-old. Targeted nutritional intervention for male old-old emphasizing antioxidant nutritional intakes may be warranted.

In order to find out the status of health care of the old aged people (age of 65 and over) in a rural area, a study was carried out, through analyzing the data of health care clinic for 207 old aged people with geriatric diseases, and of questionnired survey for 84 old aged people with geriatric diseases in a rural community. Su Dong-Myun. Nam Yang Zu-Gun, Kyung Gi-Do, Korea, during the year of 1989. The following results were obtained. 1) The composition rate of population of age of 65 and over was 9.8% in total, and sex-specific composition rate was 9.3% in male and 10.4% in female. 2) Utilization rate of health care clinic for old aged people with geriatric diseases was the highest rate with 37.9%, through individual letters at the first time, and showed gradually decreasing tendency afterward. 3) In the means of utilization advices to health care clinic for the old aged people. the individual letters(37.9%) at the first time were more effective than public information of the old aged hall or/and Myun office(18.4%). 4) In opinion on utilization of health subcenter-health care clinic for the old aged people "will utilize"(59.5%) was the highest and "do not know"(26.2%) "be difficult to utilize" (9.5%) and "will not utilize"(4.8%) were in the next order. 5) Out of 84 respondents, the old aged people With geriatric diseases, 73.8%(about three-fourths) of them answered "their diseases to the aggravated" (29.8%) "not to be changed"(25.0%) and "to be unknown"(19.0%), and the others(26.2% of them) "to be changed for the better". 6) Out of 62 respondents(the old aged people), answered their geriatric diseases not to be changed for the better, "no curative effect" was the highest with 43.5% of them. "could not know" (33.9%), "would not treat"(19.4%) and "could not be treated"(4.8%) were in decreasing order. 7) The old aged people, responded their diseases to be changed for the better, answered that they(patients) should make themselves(68.2%) responsible for basic effort of health care. However the old aged people responded their diseases not to be changed for the better answered that they should impute the responsibility of basic effort for health care to medical facilities or other conditions(63.0%). 8) In the reason of failure that the old aged people responded their geriatric diseases not to have curative effect, mis-control of regular habits of daily life was the highest(57.1%), and failure of taking selected medicine steadily(28.6%), and abuse of medicines(14.3%) were in decreasing order. 9) The reason order of being changed for the better that the old aged people responded their diseases to have curative effect, was keeping and control of regular habits of daily life (46.7%), taking selected medicines steadily(33.3%) and others (20.2%) respectively. 10) The courses of geriatric diseases itself are so chronic, duplicate and uncertain, and the old aged people activities for disease control are so slow, various and uncertain that continuous health education in home or/and community unit must be essential factors for effective geriatric health care.

This study examined how middle-aged jobholders anticipate their living after retirement, how they plan their post-retirement financial welfare and what attitude they have towards old age. The data came from 290 middle-aged male and female people in Incheon, Suwon and Cheongju city and were analyzed to find the differences among public planned pension types, such as the National Pension System (NPS), the Government Employee Pension Corporation (GEPC), and the Korea Teachers Pension (KTP). The major results were as follows: First, the expected income level after retirement in GEPC members was the highest and the lowest in KTP members. Second, the expected living period after retirement is the main criteria used when determining the amount of money needed for old age. Third, KTP members were of the most inferior at financial planning and practice, especially self-reflection of their expending behavior, thrift and saving practice for old age.

Although estrogen is known to playa role in fatty acid metabolism, it remains unclear whether fatty acid oxidation in mature female rats differs from fatty acid oxidation in peri-pubertal young rats. In this study, we measured fatty acid metabolism in the skeletal muscles and livers of 5 and 50 weeks old male and female rats. The rate of palmitate oxidation in the liver and gastrocnemius red in the 50-week-old female rats were elevated as compared to the 5-week-old females, whereas there were no differences in the male rats. The rate of palmitate oxidation in the gastrocnemius red was correlated inversely with intra-abdominal fat mass in the 5-week-old male and female rats, whereas the palmitate oxidation rate was positively correlated with fat mass in the liver and gastrocnemius red in the 50-week-old rats. HOMA-IR and plasma insulin levels were positively correlated with intra-abdominal fat mass in the pooled 50-week-old male and female rats, but this correlation was not apparent in 5-week-old rats. In summary, the rate of fatty acid oxidation measured in the middle-aged adult female rats was significantly higher than those measured in the peri-pubertal young female rats. This difference may be attributed to the influence of ovarian hormones.

Male rats of 2 months-old(young), 6 months-old(adult) and 30 months-old(old)were fed 8 or 16 weeks to investigate the e(feats of dietary fat level on the lipid metabolism in the different stages of aging. The response of 30 month old rats to dietary fat level differed from either 2 or 6-months old rats. In 30-months old rats, dietary fat level had a little effect on weight gains, lipid content of serum as compared with other two age groups. Young rats showed higher body weight gain, F.S.R, and PER compared with aged rat. The younger and the more high fat fed the rats were, the more body weight gains, FER and PER showed. Weight of liver and kidney was increased in aged rats but ratio per unit weight of liver and kidney was not affected by age. Serum lipid content was higher in aged rat compared with the young and liver lipid content was higher in high fat diet fed rats. But TG of liver and serum was not changed with aging process. Intake, excretion and absorption of lipid was not changed by age of animals. but absorption was decreased as experimental period was increased.

This study examined the relationship between social support and depressive symptom among the middle and old-aged people, using dataset of the Korean Longitudinal Study of Ageing(KLoSA 3rd). The subjects were 7,874 persons aged 45 and over. Using this data, social support variables and its relation to depressions was observed based on social network model. A multiple regression model was used to study an association between social support and depressive symptom, controlling for socio-economic characteristics, health status and behavior. Also, this paper run two subgroup regression models based on gender of subjects (male, female), controlling for confounding variables. Authors found that there was lower the number of meetings with friends (1~3 times in a week: b=0.597, p<0.0001; 1~2 times in a month: b=0.609, p<0.0001; 1~6 times in a year or under: b=1.598, p<0.0001) and negative relationship between spouse satisfaction (b=-0.007, p=0.0237), children satisfaction (b=-0.019, p<0.0001) and depressive symptom. Also quantitative effect differences were compared according to gender and its effect on depression. Compared to the male group, female group showed significant difference in quantitative effect with number of meetings with friends and spouse satisfaction, but children satisfaction didn't show clear differences according to gender. This study suggested the importance of social support for promoting mental health among the middle and old-aged people.

The purpose of this study is to analyse economic preparations for aging of the middle and old-aged and their determinants empirically, and then to discuss the findings and implications for the results of analysis. Data from The Social Statistics Survey conducted by Korea National Statistical Office are used in this study. From this dataset, 18,354 Middle and Old Citizens aged between 45 and 59 were selected for this study. The Conceptual framework for this study was based on Andersen's behavioral model and logistic model was used to investigate factors that affect economic preparation for aging. The results of this study can be summarized as follows. First, Proportion of middle and old citizen with no economic preparation for aging was high, and old-aged had lower level of economic preparation for aging than relative less aged. Second, male, education level, marital status, economic activities, recognition of present income, housing ownership, residental location, and total life condition improvement is positively and statistically significantly associated with economic preparations for aging. Third, while male, age, and economic activities is negatively and statistically significantly associated with private economic preparations for aging, education level, recognition of present income, and total life condition improvement is positively and statistically significantly associated with private economic preparations for aging. Fourth, while male, education level, marital status, economic activities, recognition of present income, housing ownership, residental location, and total life condition improvement, expectation of future income is positively and statistically significantly associated with secondary economic preparations for aging, age is negatively and statistically significantly associated with secondary economic preparations for aging.

The purpose of this study was to explore university students′ perceptions about the elderly before and after an introductory course for gerontology. Sixty-two male and female undergraduate students participated in the study as a part of the course requirement. Throughout the semester, theme students received a series of classroom lectures on gerontology, as well as participated in diverse activities to experience elderly lives. A survey was administered with the students at the beginning of the first day of class and at the end of the semester. By the end of the unit university students were more likely to have accurate conceptions of and positive attitudes toward aging and the aged. More specifically, they were more likely to (1) perceive "old" and "getting old" as a positive one, (2) seem older adults spend their time on active self-development and social activities, (3) view older adults are important, (4) change opinions about what an old person and young person do together, and (5) have a positive outlook on their own future lives as older adults.
