RESUMO
OBJECTIVES: Recently, low systolic blood pressure (SBP) was found to be associated with an increased risk of death from vascular diseases in a rural elderly population in Korea. However, evidence on the association between low SBP and vascular diseases is scarce. The aim of this study was to prospectively examine the association between low SBP and mortality from all causes and vascular diseases in older middle-aged Korean men. METHODS: From 2004 to 2010, 94 085 Korean Vietnam War veterans were followed-up for deaths. The adjusted hazard ratios (aHR) were calculated using the Cox proportional hazard model. A stratified analysis was conducted by age at enrollment. SBP was self-reported by a postal survey in 2004. RESULTS: Among the participants aged 60 and older, the lowest SBP (<90 mmHg) category had an elevated aHR for mortality from all causes (aHR, 1.9; 95% confidence interval [CI], 1.2 to 3.1) and vascular diseases (International Classification of Disease, 10th revision, I00-I99; aHR, 3.2; 95% CI, 1.2 to 8.4) compared to those with an SBP of 100 to 119 mmHg. Those with an SBP below 80 mmHg (aHR, 4.5; 95% CI, 1.1 to 18.8) and those with an SBP of 80 to 89 mmHg (aHR, 3.1; 95% CI, 0.9 to 10.2) also had an increased risk of vascular mortality, compared to those with an SBP of 90 to 119 mmHg. This association was sustained when excluding the first two years of follow-up or preexisting vascular diseases. In men younger than 60 years, the association of low SBP was weaker than that in those aged 60 years or older. CONCLUSIONS: Our findings suggest that low SBP (<90 mmHg) may increase vascular mortality in Korean men aged 60 years or older.

OBJECTIVES: The aim of this study was to evaluate the association between Agent Orange exposure and self-reported diseases in Korean Vietnam veterans. METHODS: A postal survey of 114 562 Vietnam veterans was conducted. The perceived exposure to Agent Orange was assessed by a 6-item questionnaire. Two proximity-based Agent Orange exposure indices were constructed using division/brigade-level and battalion/company-level unit information. Adjusted odds ratios (ORs) for age and other confounders were calculated using a logistic regression model. RESULTS: The prevalence of all self-reported diseases showed monotonically increasing trends as the levels of perceived self-reported exposure increased. The ORs for colon cancer (OR, 1.13), leukemia (OR, 1.56), hypertension (OR, 1.03), peripheral vasculopathy (OR, 1.07), enterocolitis (OR, 1.07), peripheral neuropathy (OR, 1.07), multiple nerve palsy (OR, 1.14), multiple sclerosis (OR, 1.24), skin diseases (OR, 1.05), psychotic diseases (OR, 1.07) and lipidemia (OR, 1.05) were significantly elevated for the high exposure group in the division/brigade-level proximity-based exposure analysis, compared to the low exposure group. The ORs for cerebral infarction (OR, 1.08), chronic bronchitis (OR, 1.05), multiple nerve palsy (OR, 1.07), multiple sclerosis (OR, 1.16), skin diseases (OR, 1.05), and lipidemia (OR, 1.05) were significantly elevated for the high exposure group in the battalion/company-level analysis. CONCLUSIONS: Korean Vietnam veterans with high exposure to Agent Orange experienced a higher prevalence of several self-reported chronic diseases compared to those with low exposure by proximity-based exposure assessment. The strong positive associations between perceived self-reported exposure and all self-reported diseases should be evaluated with discretion because the likelihood of reporting diseases was directly related to the perceived intensity of Agent Orange exposure.

OBJECTIVES: The aim of this study was to examine the levels of serum 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and evaluate their association with age, body mass index, smoking, military record-based variables, and estimated exposure to Agent Orange in Korean Vietnam veterans. METHODS: Serum levels of TCDD were analyzed in 102 Vietnam veterans. Information on age, body mass index, and smoking status were obtained from a self-reported questionnaire. The perceived exposure was assessed by a 6-item questionnaire. Two proximity-based exposures were constructed by division/brigade level and battalion/company level unit information using the Stellman exposure opportunity index model. RESULTS: The mean and median of serum TCDD levels was 1.2 parts per trillion (ppt) and 0.9 ppt, respectively. Only 2 Vietnam veterans had elevated levels of TCDD (>10 ppt). The levels of TCDD did not tend to increase with the likelihood of exposure to Agent Orange, as estimated from either proximity-based exposure or perceived self-reported exposure. The serum TCDD levels were not significantly different according to military unit, year of first deployment, duration of deployment, military rank, age, body mass index, and smoking status. CONCLUSIONS: The average serum TCDD levels in the Korean Vietnam veterans were lower than those reported for other occupationally or environmentally exposed groups and US Vietnam veterans, and their use as an objective marker of Agent Orange exposure may have some limitations. The unit of deployment, duration of deployment, year of first deployment, military rank, perceived self-reported exposure, and proximity-based exposure to Agent Orange were not associated with TCDD levels in Korean Vietnam veterans. Age, body mass index and smoking also were not associated with TCDD levels.

Family-based designs are commonly used in genetic association studies to identify and to locate genes that underlie complex diseases. In this paper, we review two examples of genome-wide association studies using family-based cohort studies, including the Framingham Heart Study and International Multi-Center ADHD Genetics Project. We also review statistical methods of family-based designs, including the transmission disequilibrium test (TDT), linkage analysis, and imprinting effect analysis. In addition, we evaluate the strengths and limitations of the family-based cohort design. Despite the costs and difficulties in carrying out this type of study, a family-based cohort study can play avery important role in genome wide studies. First, the design will be free from biases due to population heterogeneity or stratification. Moreover, family-based designs provide the opportunity to conduct joint tests of linkage and association. Finally, family-based designs also allow access to epigenetic phenomena like imprinting. The family-based cohort design should be given careful consideration in planning new studies for genome-wide strategies.

Elevated heart rate has been proposed as an independent risk factor for cardiovascular diseases, but their interrelationships are not well understood. In this study, we performed a genome-wide linkage scan in 1,026 individuals (mean age 30.6 years, 54.5% women) from 73 extended families of Mongolia and determined quantitative trait loci that influence heart rate. The DNA samples were genotyped using deCODE 1,039 microsatellite markers for 3 cM density genome-wide linkage scan. Correlation analysis was carried out to evaluate the correlation of the covariates and the heart rate. T-tests of the heart rate were also performed on sex, smoking and alcohol intake. Consequently, this model was used in a nonparametric genome-wide linkage analysis using variance component model to create a multipoint logarithm of odds (LOD) score and a corresponding P value. In the adjusted model, the heritability of heart rate was estimated as 0.32 (P<.0001) and a maximum multipoint LOD score of 2.03 was observed in 77 cM region at chromosome 18. The second largest LOD score of 1.52 was seen on chromosome 5 at 216 cM. Genes located on the specified locations in chromosomes 5 and 18 may be involved in the regulation of heart rate.

This study aims to suggest potential steps required for the integration of medical and oriental medical school by comparing the curriculum and its content between the two. The analysis was based on the specific behavioral objectives(SBOS) of the Korean Medical Association and Oriental Medical School Association. We used the school's catalog as well to get information on courses that are offered, hours, and credits. Major findings were as follows. 1. Clinical courses that are taught in oriental medical schools cover about 75% of the courses offered in medical schools on the basis of SBOS. This suggests that western medical knowledge is required for training oriental medical doctors in Korea. 2. If the SBOS of clinical medicine is taught for another 1 year at the oriental medical school, it will cover the entire content of the medical school. Also if 1.5 years of oriental medicine content is taught at medical school, it will include the whole SBOS offered in orienta medical school. Including a 1 year of clinical practicum, the extra years of required education would be 2 years for oriental medical students and 2.5 years for the medical students. Planning for an integrated for medical and oriental medicine requires close cooperation between all parties in practice and academics. A newly developed level of medicine will emerge from this if the plan takes into account the establishment of medical and oriental medical graduate schools and KMA's movement to reduce the number of SBOS to be taught in medical schools.

OBJECTIVE: The aim of this study was to identify the validity of recruiting medical checkup participants of Vietnam veterans using a mail survey, and to identify the 'Vietnam service related characteristics' and `general characteristics' of Vietnam veterans groups. METHOD: In this study, a total 900 veterans were randomly selected from the list of Vietnam veterans from 1964 to 1973. The veterans were classified into 5 groups, taking into consideration their registered status in the Ministry of Patriots and Veterans Affairs; the VRD (veterans who have agent orange-related diseases), VSD (veterans who have agent orange-suspected disease), VM (veterans who performed meritorious deeds during the war), VR (veterans who were registered with the Ministry of Patriots and Veterans Affair) and OV (other veterans) groups. By means of postal surveys, the veterans' intention to participate in the medical checkup for our research, and their socioeconomic and general characteristics were investigated. 52 surveys were returned due to the subjects not residing at the listed address, and were excluded from the analysis. RESULT: 699 of the 848 veterans (82.4%) responded to the survey, of which 619 (88.6%) intended to participate in the medical checkup for our research. The 5 veterans groups all had similar ages, Vietnam service period, Agent Orange exposure, troop characteristic and wartime class, with the exception of VM, who were older, and with a greater number of officers than the other 4 groups. There was a big difference in the health statius among the Vietnam veterans group. The VM and OV were much healthier than VRD, VSD and VR groups. The socioeconomic stati of the VRD, VSD and VR groups were lower than those of the VM and OV groups. CONCLUSION: Although there were some limitations, the recruitment, by mail, of medical checkup participants from Vietnam veterans is a valid and feasible method. The VM and OV groups were much healthier, and with higher socioeconomic stati, than the VRD, VSD, and VR groups.

OBJECTIVES: This study was to investigate the mental health status and quality of life of Korean-Chinese workers, who are residing illegally in Korea. METHODS: Total 147 illegal status Korean-Chinese workers completed to the questionnaire for demographic data, Korean version of Symptom Check List-90-Revision (SCL-90-R) and Korean version of World Health Organization Quality of Life Scale (WHOQOL-BREF). RESULTS: The results of this study showed that general mental health was relatively poor and the quality of life was relatively poorer among Korean-Chinese. Mental health and quality of life were worse among those who accompanied spouses, had no religion, had less income, and those who experienced unjust treatments such as delayed payment, violence and industrial accidents. There were significant correlations between scores of all categories of SCL-90-R and scores of domains of physical health, social relationship and environment in WHOQOL-BREF. CONCLUSION: These results suggest that Korean-Chinese laborers in illegal status in Korea need improved treatment neleved from delayed payment, social violence and industrial accidents and with extended medical service and better residential environment.

The relationship between smoking and total mortality was examined in a community residents population sample of 2,848 men and 3,543 women aged 55 years or over in Kangwha County, Korea during 1985-1991. A total of 1,436 deaths occurred during a 6-year follow-up among the 1.3 fold-higher in current smokers than in non-smokers among men. The relative risk of total mortality was highest for the 55-59 year old age group both in ex-smokers and in current smokers. PAR for total mortality attributed by smoking were estimated to be 26% for ex-smokers and 25% for current smokers in men. The biggest RR (2.1) and PAR (49%) were observed among those who smoked less than 19 cigarettes per day compared to non-smokers in males. Smokers who began to smoke at age 18 or before showed RR 1.8, and PAR 38% in men. Smoking was the most important variable related with total mortality second only to hypertensiveness not including preventable ones among men in multivariate analyses. Men who began to smoke at nineteen years of age or before had RR 1.5 for total cancer mortality. Women showed the similar picture as males in risk factors composition and in relative risks, with a low association strength, however.

The purpose of this study is to discuss the evaluation system of teaching ability of medical college faculty members. Reviewing of books and journals ha s been carried out by the authors so that the problems and methods of faculty evaluation may be discussed. The practical Korean data on the faculty evaluation system were collected by the department of faculty affairs of each college in March 1998. Faculty evaluation can be divided into two dimensions-dynamic and static dimensions. The methods vary according to evaluators, such as self evaluation, student evaluation, peer evaluation and administrator evaluation. On the bases of the object or the time of evaluation, it can be divided into formative or summative evaluation. According to the methold of data collection, it also can be divided into literature evaluation, observation evaluation and site visiting evaluation as well. The authorities of medical colleges used to give much more weight on the research activities rather than on teaching abilities. This kind of idea has been pushed faculty members to stress on research activities not on teaching abilities. Some inportant problems detected in this study are the narrow evaluation scope of aculty teaching activities, the not well established rationale of the evaluation, the underdevelopment of evaluation items, and the rigidity of the related authority. The introduction of a faculty track system is recommended as a desirable arrangement to develop the evaluation system in Korea.

One of the most important teaching methods in medical education is the holistic approach which tries to integrate basic sciences and clinical medicine. The purpose of this study is to survey the situation of integrative l ectures at Yonsei University, College of Medicine. The study identified some problems in integrative lectures. Most of residents and students do not recognize the nature of integrative lectures. Besides the survey showed that the collaboration between faculty members and departments was uncooperative. Furthermore the intergrative lectures were not able to distinguish from other lectures. The results of present study implies that it is necessary to reevaluate the program of current integrative lectures. To improve the program it is highly recommended to establish the research committee. The committee could organize a variety of seminars and workshops to diseminate information on new teaching strategies in those integrative lectures. Finally, the committee can conduct accessment of existing lectures and modify the curriculum.

Few studies have examined the effects of smoking on the morbidity and mortality of lung cancer in Korean men. In Korea, where the prevalence of smoking is among the highest in the world, the morbidity and mortality of lung cancer are rapidly escalating. The objectives of this study were to prospectively examine the effects of smoking on lung cancer and to determine the combined effects of the amount, duration and age that smoking was started. The design was a prospective cohort study with a follow-up period of six years (1993-1998). The subjects included a total of 305,687 Korean men from 35 to 64 years of age who received health insurance from the Korea Medical Insurance Corporation and who had biennial medical evaluations in 1992. The main outcome measures were deaths from lung cancer. As a baseline, 58.2% were current cigarette smokers. Between 1993 and 1998, 891 lung cancer events (34.4/100,000 people per year) occurred. In multivariate Cox proportional hazards models controlling for age, exercise and alcohol use, current smoking increased the risk of lung cancer (risk ratio [RR], 5.6; 95% confidence interval [CI], 4.2 - 7.3). There were significant dose-response relationships to the amount, duration of smoking and age that smoking was started. Compared with nonsmokers, the RR from current smokers who smoked 20 cigarettes per day for over 30 years was 8.2 (5.9 - 11.3), the RR from current smokers who smoked for over 30 years and were less then 19 years of age when they started smoking was 7.8 (5.2 - 11.9), and the RR for those who smoke 20 cigarettes per day and were less than 19 years of age when they started smoking was 8.3 (5.9 -11.6). This study demonstrates that in Korea smoking is a major independent risk factor for lung cancer, and that the risk increases with an increased amount, longer duration, and younger starting age.

Since 1998, Yonsei University College of Medicine attempted a curriculum reform focusing on clinical clerkship. The reform concentrated on the next three categories; (1) minor clinical courses following major clinical courses, (2) selecting 9 minor clinical courses out of 18, (3) introducing 'Specialized Elective Course' at the first semester of fourth year of medical school. The opinions from students and teachers on such matter were taken into consideration. The study draws its conclusion as follows; first, 'Specialized Elective Course' satisfy students' learning disposition and give guidance in shaping one's career. Second, taking the major clinical course prior to minor clinical courses give students integrated clinical experience and closer connection among the subjects. Third, switching the minor course into elective course provide expanded choice of course selection and reinforce students' motivation to learn. In general, the last two years of the new clinical clerkship showed a satisfactory result. Nevertheless, successive effort of preparing alternative measures should be made regarding the negative opinions in part. In order to do this, a school wide support system must be carried out along with the continuing interest from the students and teachers. The new attempt and study of such curriculum will outgrow the uniform and rigid education, reflecting upon the differences among students and learning goals, which ultimately help medical education to be more successful.

OBJECTIVES: To propose a feasible, valid and appropriate study designs and epidemiologic methods for evaluating the adverse health effects of Agent Orange-chemical defoliants used in Vietnam- in Korea. METHODS: A literature study was performed on Agent Orange, herbicides, pesticides and dioxins. The study subjects, study design, exposure assessment and health outcomes assessment were examined in each study. The potential data sources for the study subjects, study design, exposure assessment and health outcomes assessment in Korea were investigated. RESULTS AND CONCLUSION: In earlier Korean studies, research subjects for studying the effects of Agent Orange were identified from the patients or persons who claimed to have Agent Orange-related diseases due to the difficulties in identifying the entire population of Vietnam veterans in Korea. In this study, an attempt was made to identify the total number of Vietnam veterans in Korea. As a result, the addresses of 20,000 Vietnam veterans were obtained. It is proposed that a retrospective cohort design on a sample of the total number of Vietnam veterans is a feasible and appropriate study design. Self report questionnaires and military records were proposed to assess the exposure level. It is believed that measuring the plasma or tissue TCDD should be used only for a validation study assessing the level of exposure. For the health outcomes assessment, it is possible to obtain the mortality, cancer frequency, physical examination, screening and medical insurance record data.

It is not yet clear whether Glutathione S-transferase M1 (GSTM1) polymorphisms affect the risk of breast cancer. The aim of this study is to provide a comprehensive meta-analysis of all the available, published case-control studies on the extent of the possible association between GSTM1 polymorphisms and susceptibility to breast cancer. Twenty case-control studies on GSTM1 and breast cancer were identified using both PUBMED and a manual search. Meta-analysis was conducted by the Peto method. Subgroup analyses were undertaken, in order to explore the relationship between effect sizes and the study characteristics. The overall odds ratio (OR) was found to be 1.06 (95% CI, 0.99-1.14). The OR for post-menopausal women with GSTM1 deficiency was determined to be 1.19 (95% CI, 1.05-1.34). In populations with a low frequency of GSTM1 deficiency, a greater increase was observed (OR, 1.20; 95% CI, 1.08-1.34). Furthermore, the highest associations were found in post-menopausal women with a low frequency of GSTM1 deficiency (OR, 1.44; 95% CI, 1.20-1.73). The fact that GSTM1 deficiency is not rare in the general population implies that the attributable risk for breast cancer could be sizable. Further studies focusing on the structure of haplotype blocks of GSTM1 are required in order to find a specific haplotype with a predisposing breast cancer susceptibility allele.

The purpose of this study was to collect the informations on the current status and the needs of the physically disabled elderlies in the rural community along with the prevalence rate of these population. One study group for the study of disability status evaluation was 139 physically disabled elderlies living in the main island of Kangwha, and the other group for the study on prevalence of disability was 542 elderlies living in Songhae myun. The prevalence of physical disability was 6.5% in Songhae myun. The neurologic disorder was the most frequent diagnosis among the physically disabled elderlies followed by the musculoskeletal disorder. The time for the medical service delivery was delayed; 45.3% of the subjects received medical service more than one month after the onset of disability. Only 18.0% of the disabled elderlies received the public disability service, and 15.8% of the subjects was waiting for further service. The most common need from the subjects was the medical service, followed by the service from the institution such as a nursing home and the financial support. Registration rate of the disabled was very low(7.7%). There were only three physical therapists for the rehabilitation services in studies areas. This study revealed that the public concepts for the disability and the rehabiltation service were inadequate. We hope that this basic data can be used for the planning of rehabilitation services in this community.

OBJECTIVE: To analyze the factors affecting the participation rate in the health screening program of medical insurance. METHOD: We investigated the factors associated with the participation rate in the health screening program in Korea. Data were collected at the aggregate level from 145 employee health insurance societies and 227 self-employed health insurance societies from 1995 to 1997. Data were also collected at the individual level from four health insurance societies. This study hypothesized that the participation rate of the health screening program was related to 1) the characteristics of its members and the size of the health insurance society; 2) the specifications of the health screening program; 3) the venue of the health screening institution and the interests of individuals in the health screening program; and 4) the activities of the health insurance society. We used bivariate and multiple regression models to examine the factors on the participation rate of the health screening program. RESULTS: First, in the case of dependents of on employee health insurance society, the ratio of dependents 40 years old and over, the average monthly contribution per household, the interest and satisfaction level of individuals in health screening, and the level of refunds for over-payment were all associated with the participation rate in the health screening program, accounting for 54.4% of the participation rate. Second, in case of those insured by the self-employed health insurance society, the interest and satisfaction level of individuals in health screening, the level of refunds for over-payment, and the performance level of on-the-spot health screening were statistically significant, accounting for 40.1% of the participation rate. CONCLUSION: The factors concerning the participation rate in the health screening program of medical insurance, in both a health insurance society and for individuals, were closely related to the age and gender of individuals and household contributions.

This study analysed the correlation between student achievement and the result of medical licensure examination. To predict the result of pass or fail in the medical licensure examination we carried out a discriminant ana lysis by using following variables: year-wise student academic record and the result of integrative test scores. The prediction ratio was 83.6% and the statistical result is significant. Based on this result the formular of the discriminant score for sucess in medical licensure examination is as following: Z= -19.6372+(0.1812)xcredit of 4th year+(0.0441)xthe result of intergrative test scores. Being considered that the curriculum for seniors was consisted of as core clinical clerkships on the basis of main subjects and the items of medical licensure examination were selected from main subjects. The result is a matter of course. Therefore, it is recommended to put emphasis on core subject-oriented teaching and to strengthen core clinical clerkship to enhence the possiblity of success of medical licensure examination. Since the afore-mentioned discriminant score may predict success of medical licensure examination the school administration can decide to offer special programs for risk group students.

OBJECTIVES: This paper presents the information on the incidence of cancer from the population-based cancer resistry in Kangwha County. Material and METHODS: This investigation is based on Kangwha cancer registry. The data included cases of cancer diagnosed from 1986 through 1992. The diagnosis of cancer was confirmed by a team of physicians and nurses with the medical records kept in the clinics and hospitals based on the diagnostic criteria recommended by WHO. Home visitings were also made to cancer patients confirmed in every 6 months for the follow up and for the collection of relevant information directly from the patients. RESULTS: A total of 992 cancer cases were registered during 1986 - 1992. The age-adjusted cancer incidence rate of all site is 201.7 in men and 110.7 in women. The most common cancer is the stomach cancer in both sexes. The age-adjusted incidence rate of the stomach cancer is 65.9 in men and 25.0 in women per 100,000 population. The lung cancer(33.8) and liver cancer(27.7) are next common cancers in men. The cervical cancer(21.8) and lung cancer(8.4) are next in women. CONCLUSION: The most common cancer is the stomach cancer in both sexes. The annual age-adjusted incidence rate of the stomach cancer is 65.9 in men and 25.0 in women per 100,000 population.

OBJECTIVE: To examine the association between age at menopause and mortality in a population-based sample of women in Kangwha, Korea. METHODS: From the Kangwha Cohort, followed-up from 1985 to 1999, the data of the over 55 year old female group(n=3,596) was used in this study to examine the association between age at menopause and mortality. We calculated the all causes mortality risk ratio and the cancer mortality risk ratio by age at menopause grouping using the Cox Proportional Hazards Model with adjustments for age, BMI, smoking, education, chronic disease, self-rated health status, alcohol consumption and age at first birth. RESULT AND CONCLUSION: Compared to women who had menopause at 45-49 years, the all causes mortality risk ratio was 1.24 for women with menopause at less than 40 years(95% CI=1.01-1.53) and 1.05 for women with menopause at over 50 years(95% CI=0.92-1.20). Also, compared to women who had menopause at 45-49 years, the cancer mortality risk ratio was 1.53 for women with menopause at less than 40 years(95% CI=0.78-2.98) and 1.17 for women with menopause at over 50 years(95% CI=0.77-1.80).
