Objective: This study examined the changes in the clustering of metabolic syndrome, and examined the distribution of a combination of clustering. Methods: The study was performed with the data from the same 1,900 people who had a medical checkup at a health clinic twice from 2009 to 2013. The subjects were divided into two groups of metabolic syndrome and non-metabolic syndrome (normal group) and examined according to the periodic changes. The related factors were examined with a cohort study. Results: The order affecting the prevalence of metabolic syndrome by the combination of metabolic syndrome constituent factors was two combinations (TG+HDL), three combinations (WC+TG+HDL), and four combination (WC+TG+HDL+BP). Conclusions: To manage these factors, public health programs will be needed and the methods to prevent metabolic syndrome should be promoted. In addition, more study on the risk factors of metabolic syndrome will be needed.

Health is an important issue due to increased life expectancy. As a result, the demand for industry and services associated with individual health, health-related programs and services will be facilitated by a method to evaluate and classify the health level of an individual based on various factors. This study suggests a methodology to measure and score an individual health level. A credit scoring model was introduced to implement the categorization of variables, construct a prediction model, and to score individual health level. Cohort DB provided by National Health Insurance Service was used to illustrate overall procedures. It is expected that the suggested model can be utilized in designing and managing health care services as well as other health-related programs.

o Cohort study became the major approach to study of chronic diseases such as CVD and cancer o Cohort can be population-based or volunteer-based o Types of be population-be categorized by source population and selection mechanism o More and more cohort studies involve biological specimens, such as blood, urine, toenail, cheek cells, etc. o Multi-center and multi-national collaboration is an effective way to increase sample size. o Current statistical method typically use time-to-event analysis by Cox proportional hazard model.
