BACKGROUND: As modern epidemiologic studies began to identify obesity as a risk factor for cardiovascular disease, diabetes, hypertension, and cancer, measuring the degree of excess body fat is important on epidemiologic surveys. The evaluation of obesity level in epidemiologic surveys has been mostly done indirectly by measuring patient's height and weight. But, the anthropometry could not be done to respondents of recalling past anthropometric values or to proxy respondents. This study was attempted to elucidate usefulness of a somatotype drawing as a measuring instrument of obesity level in epidemiologic surveys in Korea. METHOD: The inclusion criteria of subjects were (1) members of the Seoul Cohort Study, who were recruited by self-administered structured questionnaire survey through mailing to the healthy men between the ages of 40 and 59 years through the program of a biennial health checkup offered by the Korean Medical Insurance Corporation (KMIC), and (2) volunteers for cancer screening program offered by KMIC. For assessing usefulness of the instrument, measurement of status/weight and self-administered questionnaire survey were done separately through the program of a biennial health checkup and of cancer screening. RESULTS: The data were collected from 138 subjects, whose Body Mass Index (kg/M2) was 23.58+/-1.46 (mean+/-SD). When the validity was measured through correlation with BMI, Spearman's correlation coefficient (rs) was 0.72 (p<0.05), that remained statistically significant after adjusting age, education level, and monthly income and occupation. And, the grades of somatotypo drawing were grouped as 1-3, 4-6, 7-8 by ANOVA and Tukey test. CONCLUSIONS: Instrument using somatotype drawing is applicable to screen degree of body fat in self-administered questionnaire surveys in Korea.

The aim of this study was to assess the degree of association between individual stress and the amount of smoking among male senior students of a medical college. The questionnaire survey was conducted twice for collecting the data on stress level in terms of BEPSl score, smoking amounts, alcohol intake, and residence type in 1992 and 1993. Among the 223 responders, 39.9% were smokers. In the smokers, the association between stress level and smoking amount was significant after controlling for alcohol intake and residence type (P < 0.l). Especially in the group of living without family, the association was more significant (p=0.06). Therefore, it is recommendable that the stress management program is called upon for the student smokers to reduce smoking amount.

After publishing results of a study that revealed diarrheagenic and emetic activity in 4-5-day old mice infected with Kudoa septempunctata (K. septempunctata) spores, the Korea Centers for Disease Control and Prevention reported 11 events of “Kudoa food poisoning” in 2015. The epidemiological design of the previous study was descriptive rather than analytical; therefore, this study aimed to further investigate the pathogenicity of K. septempunctata. Academic articles showing evidence of the pathogenicity of K. septempunctata were searched via PubMed using the citation discovery tool. Information regarding the kinds of experimental animals and inoculum spores used, as well as study results were extracted. Four articles evaluating the pathogenicity of Myxospran parasites were selected; the first article suggested the pathogenicity of K. septempunctata, while the remaining three articles reported no abnormal symptoms or histopathologic changes. Our findings indicate that there is weak evidence supporting the pathogenicity of K. septempunctata. Further studies evaluating the pathogenicity of K. septempunctata are needed urgently.

While Korea had the highest rate of increase in per capita health expenditures from 1997 to 2007 among The Organization for Economic Cooperation and Development (OECD) countries, it is necessary in all countries to establish sustainable health care systems that efficiently use the existing effective treatment methods. For dealing with the overwhelming health care crisis, the European Union and the United States (US) have launched Health Technology Assessment (HTA) and Comparative Effectiveness Research (CER) programs, respectively. Further, the Federal Coordinating Council for Comparative Effectiveness Research in US has considered the development of the CER data infrastructure to be the primary investment needed in order to reform the national health care system. The main reason is that investment in data infrastructure can potentially generate significant additional investment in CER. In addition, the Council stressed the need for coordination between CER and health information technology through a distributed network of electronic health records. These directions and decisions on driving CER in the US may provide an invaluable lesson on solving some healthcare problems in Korea. However, barriers to the potential contribution of the existing databases to CER must be overcome, including interoperability, privacy protection and confidentiality, and active participation of the holders of the related databases.

OBJECTIVES: Using the population-based cancer registry in Jejudo, we found that Jejudo had lower incidence in stomach cancer than other regions in Korea. The aim of this study was to evaluate reasons for this difference. METHODS: Citrus is the leading agricultural production in Jejudo, suggesting that lower cancer incidence in Jejudo could be explained by citrus fruit intake. We evaluated this hypothesis with quantitative systematic review (QSR). RESULTS: Stomach cancer incidence was significantly lower, with a summary odds ratio (SOR) after QSR of 0.72 [95% CI=0.64-0.81]. In addition, the SOR of pancreatic cancer tended to be lower at 0.83 [95% CI=0.70-0.98]. The SOR of prostate cancer was slightly higher at 1.03 [0.89-1.19]. CONCLUSIONS: Quantitative systematic reviews for the effect of citrus fruit intake on cancer occurrence suggested that lower cancer incidence in Jejudo could be explained by intake of citrus fruits.
