In Korea, the prevalence of dyslipidemia in the age-standardized population over 30 years old is showing an increasing trend from 35.8% to 45.1% to 48.3%. As indicated in these figures, dyslipidemia is recognized as one of the major adult diseases in this country.

In the United States, dyslipidemia is defined as meeting one of the following criteria: total cholesterol (TC) ≥ 240 mg/dl, low density lipoprotein (LDL) ≥ 160 mg/dl, triglycerides (TG) ≥ 200 mg/dl, or high density lipoprotein (HDL) ＜40mg/dl after eight-hour fasting. Dyslipidemia treatment with LDL as a primary target and TG as a secondary target is recommended in the United States. In Korea, on the other hand, the lipid profile is different such as lower HDL, TC, and LDL levels and higher TG level compared to western countries.

As for characteristics by age group in Korea, TC, LDL, and TG increase to reach the peak in the age bracket of 40 to 49 years old or 50 to 59 years old, and then decrease in the later years of age, which indicates ethnic differences in the prevalence of this disease. Due to these reasons, it is necessary to develop diagnostic criteria for dyslipidemia and a tool to calculate risks to cardiocerebrovascular diseases that better fit the situations in Korea. 

This study aims to investigate the relationship between the disease factors derived from dyslipidemic test values and health care utilizations claimed for the actual incidences of cardiocerebrovascular diseases by using the test results obtained from the Medical Examination Center Network under the umbrella of Korea Association of Health Promotion along with the insurance claim data obtained from the Health Insurance Review & Assessment Service.
