Association between Alcohol Consumption and hsCRP in Korean Adults

ABSTRACT

BACKGROUND: Cardiovascular diseases are major cause of death. In many countries, several studies reported moderate alcohol drink reduces cardiovascular diseases. High sensitivity C-reactive protein (hsCRP) is useful as a biochemical marker that can evaluate the risk of cardiovascular diseases. This study investigated the association between alcohol consumption and hsCRP. METHODS: The subjects included 769 men and 449 women who had visited a health promotion center in one university hospital from May 2006 to June 2006. They responded to self-reported questionnaire on past medical history, quantity and frequency of alcohol intake. Blood sample was taken to examine hsCRP, total cholesterol, HDL cholesterol, and triglyceride. The participants were classified into 4 groups in males and 3 groups in females by alcohol intake quantity. Using general linear model, analysis of covariance was done to evaluate the association between hsCRP and alcohol intake quantity after adjusting for smoking, body mass index, blood pressure, age, total cholesterol, HDL cholesterol, and triglycerides. RESULTS: Men who had drunk 1~4 drinks weekly had the lowest hsCRP. And a U-shaped correlation between alcohol intake quantity and hsCRP was found (P for U- shape trend test=0.059). In women, hsCRP decreased as the alcohol intake quantity increased (P for linear trend test= 0.0002). CONCLUSION: In Korean males, U-shaped relationship was found between hsCRP and alcohol intake quantity. In Korean females, inverse relationship was found between them.
