OBJECTIVES
An appropriate sampling strategy for estimating an epidemiologic volume of diabetes has been evaluated through a simulation. METHODS: We analyzed about 250 million medical insurance claims data submitted to the Health Insurance Review & Assessment Service with diabetes as principal or subsequent diagnoses, more than or equal to once per year, in 2003. The database was re-constructed to a 'patient-hospital profile' that had 3,676,164 cases, and then to a 'patient profile' that consisted of 2,412,082 observations. The patient profile data was then used to test the validity of a proposed sampling frame and methods of sampling to develop diabetic-related epidemiologic indices. RESULTS: Simulation study showed that a use of a stratified two-stage cluster sampling design with a total sample size of 4,000 will provide an estimate of 57.04% (95% prediction range, 49.83 - 64.24%) for a treatment prescription rate of diabetes. The proposed sampling design consists, at first, stratifying the area of the nation into "metropolitan/city/county" and the types of hospital into "tertiary/secondary/primary/clinic" with a proportion of 5:10:10:75. Hospitals were then randomly selected within the strata as a primary sampling unit, followed by a random selection of patients within the hospitals as a secondly sampling unit. The difference between the estimate and the parameter value was projected to be less than 0.3%. CONCLUSIONS: The sampling scheme proposed will be applied to a subsequent nationwide field survey not only for estimating the epidemiologic volume of diabetes but also for assessing the present status of nationwide diabetes control.

AbstractAbstract PDF
OBJECTIVE
The purpose of this study was to evaluate the levels of DNA damage in human lymphocytes caused by smoking and other lifestyle factors. METHODS: The study population consisted of 173 normal healthy male adults from 21 to 59 years old. The demographic and lifestyle variables were obtained from administered questionnaires. The level of lymphocytic DNA damage in the peripheral blood was evaluated by the Comet assay. Statistical analyses were done by general linear model analysis and Dunnett's multiple comparison. RESULTS: The difference in DNA damage between smokers and non-smokers was statistically significant. The means for the Tail%DNA were found to be 10.48 in the current smokers and 9.60 in the non-smokers (p<0.05). The tail moment means were 1.58 and 1.45 (p<0.05) for the current smokers and non-smokers, respectively. The number of cigarettes smoked per day did not result in a significant difference in the level of DNA damage among the smokers. Other lifestyle factors such as age, and drinking and exercise habits were not related to DNA damage. CONCLUSIONS: The DNA damage in the lymphocytes of smokers was found to be significantly higher than that for non-smokers. However, the number of cigarettes smoked per day was not related to DNA damage. Further study is needed to evaluate the relationship between the amount of smoking and level of damage to DNA. In addition, the status of DNA repair activities should be assessed.

OBJECTIVE
We intended to evaluate the double standard status and to identify factors of determining double standard criteria in multinational corporations of Korea, and specifically those in the occupational health and safety area. METHODS: A postal questionnaire had been sent, between August 2002 and September 2002, to multinational corporations in Korea. A double standard company was defined as those who answered in more than one item as adopting a different standard among the five items regarding double standard identification. By comparing double standard companies with equivalent standard companies, determinants for double standards were then identified using logistic regression analysis. RESULTS: Of multinational corporations, 45.1% had adopted a double standard. Based on the question naire's scale level, the factor of 'characteristic and size of multinational corporation' was found to have the most potent impact on increasing double standard risk. On the variable level, factors of 'number of affiliated companies' and 'existence of an auditing system with the parent company' showed a strong negative impact on double standard risk. CONCLUSION: : Our study suggests that a distinctive approach is needed to manage the occupational safety and health for multinational corporations. This approach should be focused on the specific level of a corporation, not on a country level.
