- 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
The aim of this study was to investigate the association of blood pressure levels with the common carotid artery intima-media thickness (CCA-IMT) and carotid plaques. METHODS: Data were obtained from 2,635 subjects, aged 50 years and over, who participated in the Community Health Survey (a population-based, cross-sectional study) in Dong-gu, Gwangju city between 2007 and 2008. Participants were categorized into three groups according to blood pressure levels; normotensives (<120/80 mmHg), prehypertensives (120-139/80-89 mmHg), and hypertensives (> or =140/90 mmHg). Prehypertensives were further categorized as low prehypertensives (120-129/80-84 mmHg) and high prehypertensives (130-139/85-89 mmHg). Carotid intima-media thickness and plaques were evaluated with a high-resolution B-mode ultrasound. Statistical analyses were performed using chi-square test, ANOVA, and multiple logistic regression. RESULTS: Prehypertensives had significantly greater maximal CCA-IMT values than normotensives, with a multivariate adjusted odds ratio of 1.78 (95% CI=1.36-2.32) for abnormal CCA-IMT (maximal CCA-IMT > or =1.0 mm), and 1.45 (95% CI=1.19-1.77) for carotid plaques. The multivariate adjusted odds ratio of low prehypertensives was 1.64 (95% CI=1.21-2.21) for abnormal CCA-IMT, and 1.30 (95% CI=1.04-1.63) for carotid plaques compared with normotensives. Subject with hypertension had higher frequency of abnormal CCA-IMT (odds ratio, 2.18; 95% CI=1.49-3.18), and carotid plaques (odds ratio, 1.98; 95% CI=1.46-2.67) compared with normotensives after adjustment for other cardiovascular risk factors. CONCLUSIONS: Our results indicate that there is a significant increase in the prevalence of carotid atherosclerosis in subjects with prehypertension (even in low prehypertensives) compared with normotensive subjects. Further studies are required to confirm the benefits and role of carotid ultrasonography in persons with prehypertension.

- OBJECTIVES
This study was conducted to examine the association between the carotid artery intima-media thickness (IMT), plaque and cardiovascular risk factors according to gender and age. METHODS: The data used for this study were obtained from 1,507 subjects (691 men, 816 women), aged 20-74 years, who participated in 'Prevalence study of thyroid diseases' in two counties of Jeollanam-do Province during July and August of 2004. The body mass index (BMI) and waist hip ratio (WHR) were calculated by anthropometry. The blood pressure, pulse rate, pulse pressure, total cholesterol, triglyceride, HDL cholesterol and fasting blood sugar level were also measured. Ultrasonography was used to measure the carotid artery IMT and plaque. IMT measurements were performed at 6 sites, including both common carotid arteries, and the bulb and internal carotid arteries. The definition of the 'mean IMT' was mean value obtained from these 6 sites. RESULTS: The mean+/-standard deviation IMT values were 0.65+/-0.14 and 0.60+/-0.13 mm in men and women (p<0.001), respectively. The data were analyzed according to gender and the 50 year age groups.In a multiple linear regression analysis, age and hypertension were positively associated with the mean IMT in both men and women, aged<50 years. Age, total cholesterol and smoking (current) were positively associated with the mean IMT in men (> of =50 years). Age was positively associated with the mean IMT in women (> of =50 years), but the HDL cholesterol level was negatively associated. The prevalence of plaques was 44.2%(196/443) in men and 19.4%(89/459) in women, for those greater than 50 years of age. In a multiple logistic regression analysis, age (OR=1.090, 95%CI=1.053-1.129), HDL cholesterol (OR=0.964, 95%CI=0.944-0.984), total cholesterol (OR=1.009, 95%CI=1.002-1.017) and BMI (OR=0.896, 95%CI=0.818-0.983) were independently associated with plaques in men; whereas, age (OR=1.057, 95%CI=1.012-1.103), HDL cholesterol (OR=0.959, 95%CI=0.932-0.986), pulse pressure (OR=1.029, 95%CI=1.007-1.050) and triglycerides (OR=0.531, 95%CI=0.300-0.941) were independently associated with plaques in women. CONCLUSIONS: There were significant gender and aging differences in the association between the IMT, plaque and cardiovascular risk factors. Therefore, for the prevention of atherosclerosis, selective approaches should be considered with regard to gender and age factors.

- OBJECTIVES
This study is conducted to identify the cancer incidence in Gwangju during the 5-year period from 1998 to 2002 and to assess the completeness and validity of the cancer registry data during this time period. METHODS: All cases that had a diagnosis of invasive cancer (ICD-10 sites C00-C97) during the study period were retrieved from the records of the Gwangju Cancer Registry (GCR), which theoretically includes all the cancer cases in Gwangju. All the cases during the study period were analyzed by gender, age group and cancer sites. The completeness (mortality/incidence ratio and age-specific incidence curve) and validity (histologic verification, primary site unknown, age unknown and death certificate only) of the cancer registry in Gwangju were analyzed by gender, age group and cancer sites for the 5-year period. RESULTS: The overall cancer incidence was higher in the males than in the females (age-standardized incidence rates (ASR) 299.8 and 172.4 per 100,000, respectively). In males, the most common cancer was stomach (ASR: 65.8), followed by liver (ASR: 50.5), bronchus and lung (ASR: 50.5), colo-rectum (ASR: 26.7), oesophagus (ASR: 10.6), and bladder (ASR: 10.3) in descending order. In females, the most common cancer was stomach (ASR: 26.8), followed by thyroid (ASR: 20.7), breast (ASR: 20.4), cervix uteri (ASR: 14.3), bronchus and lung (ASR: 13.0), liver (ASR: 10.7) and colo-rectum (ASR: 17.2) in descending order. The overall quality (completeness and validity) of the cancer registry was at the inigood'level. CONCLUSIONS: These results will be useful in the overall context of planning and evaluating of cancer control activities in Gwangju.

- Epidemiology is the key element of public health and preventive medicine. Reversely, public health and social equity are the basic ground for epidemiologists. Current progress in the various fields of epidemiologic study in Korea calls for the increased participation of the trained epidemiologists. Expanding epidemiologic concepts to the wide spectrum of health and medical programs, active participation to the diversified health service fields and strengthening the role of epidemiology in the social and political decision making should be included in the perspectives of epidemiology in Korea. The future of epidemiology is certainly depend on the efforts of present epidemologists.

- OBJECTIVES
To evaluate the diagnostic value of quantitative ultrasound (QUS) in the prediction of osteoporosis as defined by dual energy x-ray absorptiometry (DEXA) in postmenopausal women. METHODS: Questionnaires and height and weight measurements were used in the investigation of 176 postmenopausal women. QUS measurements were taken on the right calcaneus while bone mineral density (BMD) measurements of the lumbar spine and femoral neck were made with DEXA. The areas under the curves (AUC) of the speed of sound (SOS) for osteoporosis in the lumbar spine and femoral neck were obtained through receiver operating characteristic (ROC) analysis and evaluated. A comparison was made, for osteoporosis in the lumbar spine and femoral neck, between the AUCs of the logistic model with clinical risk factors and SOS. RESULTS: Pearson's correlation coefficients of SOS and lumbar spine BMD, and of SOS and femoral neck BMD were 0.26 and 0.37. The AUC for the logistic model in its discrimination for lumbar spine osteoporosis was 0.764, and for SOS 0.605. The AUCs for the logistic model in its discrimination for femoral neck osteoporosis and for SOS were 0.890 and 0.892, respectively. CONCLUSIONS: These results suggest that the diagnostic value of QUS as a screening tool for osteoporosis is moderate for the femoral neck, but merely low for the lumbar spine and that the predictability provided by SOS is no better than that by the sole use of clinical risk factors in postmenopausal women.

- OBJECTIVES
To evaluate the association of snoring and hypertension in a rural population. METHODS: A population-based sample of 1,763 adults in Chonnam, Korea was investigated with questionnaires and height, weight, and blood pressure measurements. Information on the demographic characteristics, cigarette smoking, alcohol consumption, hypertension and snoring was collected through a person-to-person interview using a structured questionnaire. The level of obesity was measured by the body mass index (BMI). Hypertension was considered to be present if the average of two blood pressure measurements was greater than 140mmHg systolic or 90mmHg diastolic, or if they were currently on antihypertensive treatments. RESULTS: The prevalence of snoring was 42.7% in men and 39.8% in women. With regard to age, snoring prevalence was 44.3% in the middle-aged group (45 to 64 years), greater than 33.9% in the younger (<45 years) group or 38.7% in the elderly(> or =65 years) group. The snoring prevalence increased progressively with increasing BMI, but cigarette smoking and alcohol consumption was not associated with snoring. Hypertension occurred more frequently in snorers than in non-snorers (Odds ratio: 1.25, 95% confidence interval = 1.01-1.55). However after adjusting for sex, age, obesity, smoking, and alcohol use, an effect of snoring on hypertension was no longer present (Odds ratio: 1.13, 95% confidence interval = 0.90-1.41). CONCLUSION: These results suggest that snoring might not be associated with hypertension.

- OBJECTIVES
This study aimed to estimate the completeness of cancer registration with Capture-recapture method. METHODS: The study was conducted in the population based cancer registry of Kwangju, Korea, for which there are three main sources of notification: reports by Korean Central Cancer Registry, reports by pathology data, and the others reports by radiology data, death certificates, etc. The defined cases in three sources were matched by 13 digits Resident Register Number. To derive an estimates, log-linear models were applicated. RESULTS: Overall completeness was estimated to be around 93%. There was some variation with age(consistently high levels below age group 60-74 years, a minimum of 88.6% above 75 years). Among the most common cancer sites, estimates of completeness were highest for thyroid cancer(97.1%), while lower estimates of completeness were derived for stomach cancer(92.3%), liver cancer(92.6%). CONCLUSIONS: Careful application of Capture-recapture method may provide an alternative to traditional approaches for estimating the completeness of cancer registration in Kwangju city.

- OBJECTIVES
This 3-year longitudinal study was conducted to evaluate the influence of self-rating health perception on health care utilization and all cause-death risk. METHODS: The hypothesis was tested using a community-based samples, among which subjects 3,414 were interviewed in 1995. Self-rating health perception was assessed by single-item question. Three components of health care utilization amount(number of visits, number of medications, yearly health care expenses) per year were measured using medical insurance data during 3-year follow-up period among subjects in district health care insurance. There were 123 deaths from all causes among 3,085 subjects interviewed. RESULTS: The results showed that those who had poor health perception revealed more increases in the amount of health care utilization than good health perception group (p<0.05). After adjusting for age and sex, the poor health perception group had higher death risk over 3 years than good health perception group(hazard ratio=1.88). but, after adjusting health care utility, supplementary, was not significant. CONCLUSION: These results suggest that self-rating health percep-tion was associated with difference in health care utilization and all cause-death risk.

- 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.

- 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.

- 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.

- This study investigated the stress of community residents in Kwang-Ju and Chonnam areas by using the General Health Questionnaire(GHQ-60) as a instrument of stress measurement. The number of subject were 445 residents who lived in three areas (large city, middle city, and rural area) and they were individually interviewed in March, 1994. The result of study showed that the degrees of stress measured by GHQ-60 were statistically significant in the residents' area, age. sex variables: (a) the residents in middle city among three area had the highest level of stress: (b) the resident who were more than 60 in age had the highest level of stress: (c) the female resident had more stress than male residents: (d) particularly, the residents who were more than 60 years old in the middle city had the highest level of stress. Further, the results of factor analysis showed that there were three factors of social dysfunction, depression and anxiety, and psychosomatic symptom. The social dysfunction factor was statistically significant in both age and resident area variables. The depression and anxiety factor was statistically significant in the residents' area, age. sex variables. The psychosomatic symptom factor was statistically significant in both age and sex variables. The study suggested that they should give a special attention to solve the old people's stress because stress was closely related to residents age.

- The genetically determined ability to metabolize debrisoquine(DBR) is related to risk of lung cancer and DBR hydroxylation exhibits wide inter-individual variation. In this study, 100 korean adults were tested for their ability to metabolize DBR. The DBR metabolic phonotype were determined by metabolic ratio (MR, DBR/4-HDBR) which is the percent dose excreted as unchanged DBR divided by the percent dose excreted as 4-hydro-xydebrisoqinne(4-HriBR) in a aliquots of an eight hour urine sample, after 10 mg DBR test dose administration. Analysis was performed on a capillary gas chromatography fitted with electron capture detector. The results were as follows; 1. Geometric mean or DBR MR was 0.32 in male, 0.27 in female, 0.30 in total and the distribution of log(MR) was seemed to follow normal distribution. 2. Metabolic ratio of DBR was higher in non-smoker and non-drinker than in smoker and drinker without any statistically significant difference. 3. None of personal factors was significantly related to DBR MR except age. 4. The DBR metabolic phonotype was extensive metabolizer(EM) 93, intermediate metabolizer (IM) 7 by traditional method and EM 98, IM 3 by Caporaso's method. The poor metabolizer (PM) phenotype was not found by either method. 5. Maximal expected PM phenotype was 0.36% by traditional method and 0.04% by Caporaso's method.

The results obtained were as follows: 1. Symptom complaints were higher and Flicker test values were lower in exposed workers than in unexposed workers. 2. Flicker values were inversely correlated with urinary Hippuric acid concentration in exposed workers (r=-0.26, p<0.05). 3. Flicker values were inversely correlated with subjective symptom score (r=-0.15, p<0.05). Low Flicker value were also related with some subjective symptoms such as "Dimmed vision", "Nightmare", "weakness on extremity" in workers as a whole. While symptoms of "Dimmed vision", "Nightmare" only observed among exposed workers.

- In order to investigate the occurrence characteristics of cancer in terms of industry in Kwangju-Chonnam area, medical utilization records of industrial medical insurance corporations during the period of 1987 to 1988 were reviewed for the identification of neoplastic disease. The cases obtained from the medical records were followed up for the verification and to get additional information. Standardized incidence data were compared by occupational characteristics. Multiple logistic regression analysis was applied to analyze the difference of incidence or distribution of cancer as a whole or of some selected cancer. Total cases of cancer identified were 242 during the study period. Annual incidence rate was calculated as 123.1 per 100,000 person. The frequent types of cancer were cancers of stomach, liver, lung, colon and rectum, bladder and lymphoma in descending order. Employees of mine and other sand handling industries showed significantly higher risks for cancer of stomach and cancer as a whole. Employees of the transportation industry showed the higher risk for cancer of liver. Workers in small-sized industry (< or = 100) had a higher risk for cancer than who in large-sized industry (>100). These findings suggested the effect of occupational environmental exposure to cancer development.

Abstract

- The exposures to carbamate pesticides (BPMC specifically) of agricultural workers were estimated by collecting pesticide in air by personal sampler and by analyzing with gas chromatography. Data revealed that the highest BPMC concentration in the aspirated air was 7.7 mg/m3. Concentrations were generally higher in the group whose spray conditions were controlled than the group uncontrolled. Actual concentrations were relatively lower than the values predicted theoretically. These findings suggest that personal sampler be useful in the estimation of pesticide exposure.

Abstract

- To evaluate the possible functional role of serum during the process of parturition, 15 serum samples were collected and analyzed for the nickel concentrations in each 3 groups(Group 1 for the period during parturition, Group 2 for the period from delivery of fetus to delivery of placenta, and Group 3 for the period after delivery of placenta) of normal, uncomplicated full term vaginal delivery and one control group composed of healthy unmarried women in 3rd decades of age. Data revealed that average serum nickel concentration of Group 2(26.6 microgram/l) and Group 1(22.2 microgram/l) were significantly higher than that of Control group(13.7 microgram/l), but Group 3's(13.8 microgram/l) was almost same as Control group's. There were significant negative correlation between age and serum nickel concentration in group 2, and a tendency of higher nickel concentration in women who have no previous experiences of pregnancy than who have previous experiences of pregnancy, although it was not significant. These result could be indicative of close causal relationship between serum nickel concentration and the entire process of parturition.

Abstract
PDF
- During 2 months from December 1979 to January 1980, Medical practitioners in chonnam province were grouped into Si (city), Eup(town) and Myun (rural area) groups according to the locations of their clinic. 40 practitioners were randomly selected in each group and were asked their opinions about rural medical care in general. Total of 88 practitioners replied to the question as 73.3 percent of response rate in average. The most frequently mentioned advantages of rural practice were ease of clinic opening in Si-and Myun-group respondents and good social relationship in Eup-group respondents. The most frequently mentioned disadvantages were medical isolation in Si-group respondents and resident's ignorance in medicine in Eup-and Myun-group respondents. In all groups, most respondents though that rural medicine care should be delivered by and controled by physician. Suggestions made by Eup-and Myun-group respondents for improving rural medical care by structural change focused on the regional medical insurance system, while Si-group respondents noted district hospital or hospital linkage as most preferable system.
