OBJECTIVES
The American Diabetes Association (ADA) has recently recommended the HbA1c assay as one of four options for making the diagnosis of diabetes mellitus, with a cut-point of > or =6.5%. We compared the HbA1c assay and the fasting plasma glucose level for making the diagnosis of diabetes among Korean adults. METHODS: We analyzed 8710 adults (age 45-74 years), who were not diagnosed as having diabetes mellitus, from the Namwon study population. A fasting plasma glucose level of > or =126 mg/dL and an A1c of > or =6.5% were used for the diagnosis of diabetes. The kappa index of agreement was calculated to measure the agreement between the diagnosis based on the fasting plasma glucose level and the HbA1c. RESULTS: The kappa index of agreement between the fasting plasma glucose level and HbA1c was 0.50. CONCLUSIONS: The agreement between the fasting plasma glucose and HbA1c for the diagnosis of diabetes was moderate for Korean adults.

OBJECTIVES
This study was aimed at investigating the medical service utilization pattern of patients who use public medical aid compared to those who have health insurance. METHODS: We selected every patient between the age of 18 and 69 who used public medical aid from January 1, 1999, to December 31, 2001, in Gwangju metropolitan city, South Korea. For comparison, a list of patients with health insurance was gathered for same period. Then the medical records of those who had been hospitalized for acute appendicitis were selected among both groups. Of those records, we compared the number of cases of ruptured appendicitis to cases of whole acute appendicitis in both groups. Regarding coding for ruptured appendicitis, International Classification of Diseases - 10 (ICD-10) was used. Multiple logistic regression was used as a statistical tool to determine the effectiveness of risk factors. RESULTS: Even after adjusting for risk factors, such as age and sex, the proportion of perforation of acute appendicitis among public medical aid patients was found to be significantly higher than among insured patients. CONCLUSIONS: This comparative study on ruptured appendicitis among public medical aid patients and insured patients, indicates that the proportion of perforation of acute appendicitis could be an index showing that these types of patients utilize medical services differently than insured patients. We know that when abdominal pain is not properly treated at the outset, it easily develops into ruptured appendicitis complicated with peritonitis. Considering this data analysis, we guess the public medical aid system to have significant problem with medical accessibility. So additional and systematic research on the pattern of utilization of medical services of public medical aid patients is needed.

OBJECTIVES
To evaluate the accuracy of the registered cause of death in a county and its related factors. METHODS: The data used in this study was based on 504 cases, in a county of Chonnam province, registered between January and December 1998. Study subjects consisted of 388 of the 504 cases, and their causes of death were established by an interview survey of the next of kin or neighbor and medical record surveys. We compared the registered cause of death with the confirmed cause of death, determined by surveys and medical records, and evaluated the factors associated with the accuracy of the registered cause of death. RESULTS: 62.6% of the deaths were concordant with 19 Chapters classification of cause of death. external causes of mortality, endocrine, nutritional and metabolic diseases, neoplasms and diseases of the circulatory system showed the good agreement between the registered cause of death and the confirmed cause of death. The factors relating to the accuracy of the registered cause of death were the doctors' diagnosis for the cause of death (adjusted Odds Ratio: 2.67, 95% Confidence Interval: 1.21-5.89) and the grade of the public officials in charge of the death registry (adjusted Odds Ratio: 0.30, 95% CI= 0.12-0.78). CONCLUSIONS: The accuracy of the registered cause of death was not high. It could be improved by using the doctors' diagnosis for death and improving the job specification for public officials who deal with death registration.

AbstractAbstract PDF
The purpose of this study is to compare the level of health-related quality of life and relating factor between institutional elderly and community living elderly. The subjects were 390 from Sanatorium or Nursing home and 467 from the community, in Kwangju. The results are followed : l) A comparison of ADL between two groups, institutional elderly and community living elderly, resulted in that community elderly were more significantly independent in the areas of bathing and transfer than institutional elderly. 2) A comparison of IADL between two groups resulted in that ; Community elderly, were more independent in the areas of using telephone and transportation, food preparation, house keeping, and doing laundry. Institutional elderly were more independent in the area of handling finances. 3) In the case of poor health-related quality of life, institutional elderly showed 2.4 times in the dimension of physical fitness, l.8 times in daily activity, 2 times in social activity, 2 times in pain, 26.7 times in social support, and 0.4 times in subjective quality of life higher than community elderly. There was no significant differences in the rest of dimensions. 4) In institutional elderly, the analysis of variables related to the health-related quality, of life resulted in that; The relating factors were sex, education, and chronic illness in the dimension of physical function. Direct contact with family or significant others in the dimension of social activity. Chronic illness in the dimension of pain and perceived health status. Direct or indirect contact with family or significant others over the phone or through letters in the dimension of social support. 5) The analysis of variables relatd to the health-related quality of life showed that community elderly has more relating variables in each area than institutional elderly. The relating factors were age, sex, and chronic illness in the dimension of physical function. Education and chronic illness in the dimension of emotional status. Age and chronic illness in the dimension of daily activity and social activity. Education and chronic illness in the dimension of pain and perceived health status. Sex, education, family size in the dimension of social support. Education and chronic illness in the dimension of subjective quality-of-life. Throughout general daily activity, community elderly showed more satisfactory results than institutional elderly, but in the subjective area of health-related quality of life, such as subjective quality of life, institutional elderly, group showed more positive results. And community elderly had more relating factors than institutional elderly. For the health care of the elderly that focused on quality, of life, new approaches considering the characteristics of both group, institutional and community, living elderly, are needed.

AbstractAbstract PDF
The purpose of this study was to examine the mortality risk associated with cognitive impairment among the rural elderly. The subjective of study was 558 of 'A Study on the Depression and Cognitive Impairment in the Rural Elderly' of Jung Ae Rhee and Hyang Gyun Jung's study(1993). Cognitive impairment and other social and health factors were assessed in 558 elderly rural community residents. For this study, a Korean version of the Mini-Mental State Examination(MMSEK) was used as a global indicator of cognitive functioning. And mortality risk factors for each cognitive impairment subgroup were identified by univariate and multivariate Cox regression analysis. At baseline 22.6% of the sample were mildly impaired and 14.2% were severely impaired. As the age increased, the cognitive function was more impaired. Sexual difference was existed in the cognitive function level. Also the variables such as smoking habits, physical disorders had the significant relationship with cognitive function impairment. Across a 3-year observation period the mortality rate was 8.5% for the cognitively unimpaired, 11.1% for the mildly impaired, and 16.5% for the severly impaired respondents. And the survival probability was .92 for the cognitively unimpaired, .90 for the mildly impaired, and .86 for the severly impaired respondents. Compared to survival curve for the cognitively unimpaired group, each survival curve for the mildly and the severely impaired group was not significantly different. When adjustments models were not made for the effects of other health and social covariates, each hazard ratio of death of mildly and severely impaired persons was not significantly different as compared with the cognitively unimpaired. But, as MMSEK score increased, significantly hazard ratio of death decreased. Employing Cox univariate proportional hazards model, statistically other significant variables were age, monthly income, smoking habits, physical disorders. Also when adjustments were made for the effects of other health and social covariates, there was no difference in hazard ratio of death between those with severe or mild impairment and unimpaired persons. And as MMSEK score increased, significantly hazard ratio of death did not decrease. Employing Cox multivariate proportional hazards model, statistically other significant variables were age, monthly income, physical disorders. Employing Cox multivariate proportional hazards model by sex, at men and women statistically significant variable was only age. For both men and women, also cognitive impairment was not a significant risk factor. Other investigators have found that cognitive impairment is a significant predictor of mortality. But we didn't find that it is a significant predictor of mortality. Even though the conclusions of our study were not related to cognitive impairment and mortality, early detection of impaired cognition and attention to associated health problems could improve the quality of life of these older adults and perhaps extend their survival.

AbstractAbstract PDF
In other to study relationship of anxiety and serum cholesterol in general population, we performed the interview survey and screening test for the Ju-am cohort and residents in controlling area at 1995. Among them, 622 people are selected for this analysis. The results were summarized as follows. 1. Anxiety and total serum cholesterol related each other in the group of anxiety. Correlation coefficient was 0.39(p<0.01). 2. According to the result of multiple regression that the total serum cholesterol regarded as the dependent variable, anxiety and total serum cholesterol were related each other positively in the group of anxiety(p<0.05). 3. As the symptoms of anxiety was dichotomized affective and somatic symptom. There was no relationship of 2 symptoms and total serum cholesterol in all subjects, but there was more relationship on the affective symptom than on the somatic symptom in the group of anxiety(p<0.05). The above results show that anxiety and total serum cholesterol related each other significantly in the anxiety group. And the relationship of psychological factors and serum cholesterol could be applied significantly in general population as well as in the special group.

AbstractAbstract PDF
Obesity usually is defined as the presence of and abnormally amount of adipose tissue. In many epidemiologic study, obesity as a health risk factor has been estimated by Body Mass Index(BMI) in general. This study was conducted to review of body fat percent measured by Bioelectric impedance analyzer as a estimator of obesity in a rural adult population. The study subjects were 421 men and 664 women who reside in the area on the Juam lake. They were sampled by multistage cluster sampling. Their mean age was 59 years old. Body fat percent increased with age, but BMI decreased with age in this study. Body fat percent was more larger at female and elder on the same BMI. The correlation coefficient between with body fat percent and body mass index was low (r=0.4737). Body fat percent was explained by not only BMI but also sex and age (r(2)=0.63). The result suggested that it is inadequate for BMI only to estimate obesity about elderly person who reside in the rural community. The relation of body fat percent and body mass index of this study agreed with the preceding knowledges and studies in general.

AbstractAbstract PDF
This study was conducted to evaluate the accuracy of the official death registry in rural area. The base data used for the study was 379 deaths registered during the period of 1993 and 1994 in 4 rural townships of Chonnam Province. The interview survey for cause-of-death was performed on the next of kin and/or neighbor. Additional medical informations were collected from hospitals and medical insurance associations for the purpose of verification. The underlying cause-of-death of 278 cases presumed by the survey was compared to the cause on official death registry. There was a prominent disagreement of cause-of-death between the survey data and the registry data(agreement rate: 38.9~44.6%%, according to disease classification method). These results may be caused by extremely low rates of physicians' certification, which were mostly confined to the poisoning and injury. Symptoms, signs, and ill defined conditions on death registry could be classified into circulatory disease(32.3%), neoplasm(21.2%), digestive disease(7.l%), injury and poisoning(7.l%) and so on. These results suggest that careful attention and verification be required on utilization of death registry data in rural area.
