This study was conducted in order to determine health effects of socio-psychological stresses in Taegu Area from march 1 thorough march 31, 1998. Three hundred and thirty three subjects(168 males and 165 females) were randomly selected and interviewed by trained interviewers according to questionnaires. The results are summarized as fellows; 1. Health statuses by age, education religion, marital status, occupation and family income were significantly different. 2. The factors which had significant influences on Health status ware vitality, depression and general feeling of subjects' health. 3. Health status were directly influenced by the age(direct effect=-0.014), vitality(direct effect=0.473), and general feeling of subjects' health (direct effect=0.222), but, was indirectly influenced by education degree (indirect effect=0.010), income(indirect effect=0.039), and mental depression(indirect effect=-0.069). The variabilities which were both directly and indirectly influenced, were the age (direct effect=-0.014, indirect effect=-0.002), vitality(direct effect=0.473, indirect effect=-0.071).

Objectives: The purpose of this study was to estimate the mediating effect of subjective unmet healthcare needs on poor health. The mediating effect of unmet needs on health outcomes was estimated. Methods: Cross-sectional research method was used to analyze Korea Health Panel data from 2011 to 2015, investigating the mediating effect for each annual dataset and lagged dependent variables. Results: The magnitude of the effect of low income on poor health and the mediating effect of unmet needs were estimated using age, sex, education level, employment status, healthcare insurance status, disability, and chronic disease as control variables and self-rated health as the dependent variable. The mediating effect of unmet needs due to financial reasons was between 14.7% to 32.9% of the total marginal effect, and 7.2% to 18.7% in lagged model. Conclusions: The fixed-effect logit model demonstrated that the existence of unmet needs raised the likelihood of poor self-rated health. However, only a small proportion of the effects of low income on health was mediated by unmet needs, and the results varied annually. Further studies are necessary to search for ways to explain the varying results in the Korea Health Panel data, as well as to consider a time series analysis of the mediating effect. The results of this study present the clear implication that even though it is crucial to address the unmet needs, but it is not enough to tackle the income related health inequalities.

Objectives This study aimed to investigate the effect of social capital, health risk behavior and health status on medical care utilization by the elderly. The data and Research method Data were obtained from the 4th wave survey of the Korea Welfare Panel Study. 4,087 household members aged 65 years and over were subject to analysis. Descriptive statistics are used to describe the basic features of the data in a study. we performed a structural equation modeling(SEM) analysis to evaluate the effect of social capital and mediating effect of health risk behavior and health status. Results Results showed that factors related to medical care utilization of the elderly were different depending on types of service (inpatient and outpatient service) except health status. Age, higher social capital, more health-risk behavior and poorer health status were associated with increased use of inpatient service. Social capital was found to have a positive direct effect on it. Also, social capital had an indirect effect on reducing use of inpatient services by improving health status. On the other hand, lower age and higher household income tended to increase use of outpatient service, while higher social capital and higher health status were inversely related. Social capital had a direct effect and an indirect effect on reducing use of outpatient service and, at that time, health status played a mediating role. Conclusions Social capital may contribute to improve health status and indirectly reduce medical care utilization of the elderly by enhancing their health status. These results provide evidence that more policy and strategy considerations should be needed for the elderly to strengthen their social capital in order to enhance their levels of health and more efficient utilization of medical care.

Healthy worker effect (HWE) refers to the consistent tendency for actively employed individuals to have a more favorable mortality experience than the population at large. Although HWE has been well known since the 1970s, only a few studies in occupational epidemiology have attempted to fully define and evaluate HWE. HWE can be separated into effects on the initial hiring into the workforce (healthy worker hire effect) and those on continuing employment (healthy worker survival effect). In this review, we summarize the methods for minimizingor adjusting for the healthy worker effect available in occupational epidemiology. It is noteworthy that healthy worker survival effect appears complicated, considering that employment status plays simultaneous roles as a counfounding variable and intermediate variable, whereas healthy worker hire effect may be adjusted by incorporating health status at baseline into the statistical model. In addition, two retrospective cohort studies for workers in the semiconductor industry and Vietnam veterans in Korea, respectively, were introduced, and their results were explained in terms of healthy worker effect.

Purpose: The purpose of this research was to determine the effect of an exercise program on the health status and depression in the elderly. Method: The research design was a nonequivalent control group pre-post test design. The exercise program (experimental group) consisted of 22 elderly over a period exercising for 12weeks, 3 days/week. The phone counselling about exercise and health(control group) was applied for 12 weeks for 10-15minutes/day/week. To identify the health status SF-36 was utilized and the GDS was used for depressionanalysis. The data was collected from May 2001 to July 2001. Result: The effect of the exercise appeared significant in the subarea of health status (physical function, physical role, mental health, general health) and depression. The effect of the phone counselling was appeared significant in subarea of health status - bodily pain. The effect of the exercise and the phone counselling did not appear significant. Conclusion: The exercise designed for the elderly promotes health in the elderly and further evaluation about the effect on exercise and phone counselling is needed.

Background: This study was conducted to analyze the impact of having a usual source of care on health behaviors of the middle aged and the elderly, in order to investigate the potential effect of enhancing primary health care in a Korean context. Methods: This study constructed a balanced panel of middle-aged and elderly samples using the Korea Health Panel 2016-2018, and fixed-effect models were used to analyze the data. Results: Among three sets of dependent variables (physical activity, smoking, drinking), statistically significant results were found only in physical activity. Subgroup analysis showed that this effect was not observed in the late elderly (aged 75 and older) and those without chronic diseases. Conclusion: Results of the study implied that enhancing primary health care among middle age and the elderly may have an effect on improving health behaviors. Moving forward to person-centered primary health care from disease-focused primary health care should be considered in high-risk groups such as the middle aged and the elderly with chronic diseases.

It's now time for adopting u-Health according to development of internet. It is judged that it needs to research on effect of using internet health information targeting University students who are the most sensitive of internet health information. So we analyzed effect of using internet health information according to internal and external health control materials with 300 University students. As a result, If a rate of investment to the health is high, an effect of internet health information also increases as B=.004, rate of internal health control is high, it decreases as B=-.027 and rate of external health control is high, it increases as B=.037. For a University student who has steady faith about health and can control their internal health more easily, the effect of using internet health information has decreased. And for a University student who has high inclination of external dependence about health and can control their external health more easily, the effect of using internet health information has increased. So it needs to raise credibility, accuracy and accessibility of internet health information.
