Objectives: The purpose of this study was to investigate the effect of handgrip strength level on cognitive impairment in hypertensive patients. Methods: This study used the first to eighth year data of the Korean Longitudinal Study of Aging (KLoSA). Of the 10,254 respondents who participated in the basic survey, respondents were included that they were diagnosed with high blood pressure and had no cognitive impairment. The handgrip strength was based on the highest value of handgrip strength for both hands. Cognitive function using MMSE results and 23 points or less were defined as cognitive impairment. Cox models were conducted to estimate the hazard ratios (HRs) of cognitive impairment in relation to handgrip strength adjusting for covariates. Results: In the case of hypertension patients, the probability of cognitive decline decreased by 3.0% every time the maximum handgrip strength increased by 1 unit. In the analysis by age, under the age of 64 had a 1.8% decrease in the probability of cognitive decline whenever the maximum handgrip strength increased by 1 unit, and a 3.6% decrease in those over the age of 65. In the gender analysis, male had a 3.2% decrease in the probability of cognitive decline for every 1 unit increase in the maximum handgrip strength, and female had a 2.6% decrease. Conclusions: The results of this study are expected to be used as basic data for the development of interventions to prevent cognitive decline in hypertensive patients by identifying the effect of handgrip strength level on cognitive decline. It is also expected to be used as basic data for health education on the necessity of increasing muscle strength for hypertension patients in the community.

Using the first wave of KLoSA(Korean Longitudinal Study of Ageing) beta version, this study analyzed factors affecting early retired men's subjective life satisfaction through Binary Logit and Multiple Regression. Total 552 men were selected as a sample. The main results of empirical analysis in this study were as follows: The retirement reason(health-) and monthly household income(+) affected whether they were satisfied with the retirement life or not and subjective life satisfaction over all. Especially, the retirement reason(health-) had a stronger effect on whether early retired min were satisfied with the retirement life or not and their subjective life satisfaction than monthly household income revealed significant variable in previous studies. This result represents that the retiree's life satisfaction analysis model must include retiree's characteristics at the time of retirement as well as retiree's current status characteristics or socio-economic characteristics.

Purpose: The purpose of this study is to examine factors affecting quality of life among grandparents raising their grandchildren. Methods: This study carried out a secondary analysis of data from the 2014 Korean Longitudinal Study of Aging (KLoSA) and Statistics Korea. Data collected from 224 grandparents who reported raising their grandchildren were analyzed using descriptive statistics, independent t-test, ANOVA, pearson correlation coefficient, and multilevel regression analysis. Results: The mean score of the participants' quality of life was 62.63. Significant predictors of quality of life of the grandparents included subjective health status, last year's total house income, number of last year's travels, frequency of last year's movie seeing, and number of children's parks per 100,000 population. Conclusion: These results suggest that public health nurses in improving quality of life of grandparents focus on children's parks and formal social supports as community factors as well as regular exercise as an individual factor in order to be more effective.

Using data from Korean Longitudinal Study on Aging (KLoSA), this study examines how continuity and change of marital status is associated with health over time among older women, focusing on the moderating effects of age and parent-child relationships. KLoSA data set has two waves of interviews, and for this study, 2046 women aged 65 and over were selected. To analyze data, Structural Equation Modeling (SEM) was used. The major findings are as follows. First, there was no statistically significant difference in health between continuously married older women and continuously single older women. However, older women who had transition from being married to being single showed lower physical health than continuously married and continuously single older women. Second, there were statistically significant differences in the effect of marital status on mental health according to the age of older women. Older women who had transition from being married to being single showed lower mental health than continuously married elders when older women were younger. Third, contact with children moderated the effect of marital status on physical health. Older women who had transition from being married to being single showed lower physical health than continuously single and continuously married older women when older women had less contact with their children. The findings imply after the loss of marital role, older women's relationship with adult children plays a significant role in promoting health. In conclusion, the findings of this study show the different pathways through which marital status is associated with health for 3 different groups of older women, being continuously single, being continuously married, and making transition from being married to being single.

This study performed a series of analyses to examine the effects of regular exercise on depression using data from the HAS (Hallym Aging Study) and the KLoSA(Korean Longitudinal Study of Ageing). The effect of regular exercise on depression was tested through propensity score matching methods. In addition, analyses of five indirect effect models were performed to verify a theoretical description about how regular exercise has an effect on depression. The results of analysis were as follows. First, it was found in the two samples that elderly people who exercise regularly have a lower level of depression compared to those who do not. Second, the results of analysis of five indirect effect models were all significant. The psycho-physiological models showed the effect of regular exercise on depression using ADL(Activities of Daily Living) and grip strength. The psycho-social models also demonstrated the effect of regular exercise on depression using variables related to social activities. Based on these findings, intervention strategies to prevent depression was discussed.

This study analyzes differences of self-rated health status between Korea and three European countries. Self-rated health status is highly correlated with objective health status such as chronic diseases and ADL(Activities of Daily Living)/IADL(Instrumental Activities of Daily Living), but it is also influenced by individual attitude or belief about health. Therefore, differences of self-rated health status among countries are determined by the combination of (1) differences of objective health status and (2) socio-cultural characteristics affecting individuals' attitude and belief. Using 'Korean Longitudinal Study of Ageing(KLoSA 2006)' and 'Survey of Health, Ageing, and Retirement in Europe (SHARE 2004)', we found that Korean older people are more likely to feel negatively on their health status than their European counterpart. The findings are explained in two different ways. First, how strongly the objective health status affects on the subjective health status varies among countries. Korean older people with chronic diseases are more likely to evaluate their health status negatively because of the diseases than their European counterparts do. Second, after controlling the effects of the objective health condition, the subjective health status of Korean older people is still lower than that of the European elderly.
