Health related practices and chronic illness in Korea

Korean American health insurance and health services utilization

The purpose of this ethnic group study was to describe the unique pattern of Korean Americans, as compared with the aggregate of Asian Americans, for: (a) the predisposing, enabling, and need factors for health service utilization, focusing specifically on the role of health insurance coverage; and (b) predictors of health insurance coverage. Using the behavioral model for health service utilization, data were selected from the 1992 National Health Insurance Survey (NHIS, 1994) for Korean Americans (n = 345) and Asian Americans (n = 3,059). Results differed between the Korean American group and the Asian American group. Health insurance coverage was the strongest predictor of Korean American utilization, and need factors lacked significance, suggesting that uninsured Korean Americans have less access regardless of need. For the aggregate Asian American group, need factors tempered the influence of health insurance on utilization. Results of this type of study may be helpful for designing and implementing health care services tailored for specific ethnic at-risk markets.

Development of a health risk appraisal for the elderly (HRA-E)

The purpose of this project is to develop a health risk appraisal for the elderly (HRA-E) and test its application in both medical and nonmedical settings. The HRA-E system consists of a questionnaire and software for computer-generation of personalized reports to participants, 55 years and older, and their physicians. Items in the questionnaire cover a comprehensive range of content domains relevant to health promotion in the elderly. The goal of the HRA-E system is to prevent functional decline. Samples of eligible subjects from the American Association of Retired Persons (AARP), a group practice, and a senior center were extended invitations to participate. Those responding affirmatively to the invitation were given a questionnaire and evaluation form. Each person who returned the questionnaire received his or her personal report and a second evaluation form. Four months after receiving their reports, respondents were questioned about behavior changes during the interim. Preliminary findings, based on 1895 respondents, indicate that nearly all participants found the questionnaire easy to complete and were pleased with its overall length. In addition, most participants read their reports, and many planned to take action, based on report recommendations. In the next phase of this project, the intent is to refine the questionnaire, extend the intervention protocols for longitudinal application, and evaluate its impact on health-related behaviors, medical care utilization, and functional decline.

Health consciousness in relation to education in Korea--focusing on seven preventable health risk factors

This research was carried out to investigate the relationships of a set of several selected sociodemographic variables with a group of health-related practices with special emphasis on educational attainment. The sample consisted of 5,245 adults aged 20-59 selected through stratified cluster random sampling. Univariate, multiple logistic regression and canonical correlation procedures were employed for analyses. It was found that educational attainment was independently associated with at-risk health behavior; the less educated had less desirable health habits than the more educated. Pattern of at-risk health behavior varied with educational level; the significant health-related practice variables among the seven factors were cigarette smoking, heavy alcohol drinking, physical inactivity, being overweight, and inadequate sleeping. These findings suggested that the less educated should be given higher priority in health education programs for the identified health risk behavior and in the formulation of related health policies.
