Abstract
Background
: Elevated plasma total homocysteine is a risk factor for cardiovascular diseases. The authors investigated the parameters such as habit, body index, cardiovascular risk factors, nutrition relative to the plasma homocysteine concentration.

Methods : The subjects were 6,223 adults (3,377 males, 2,846 females) who were over 18 years of age and visited a health promotion center of a university hospital from March 2002 to January 2003. We assessed the relationship between the homocysteine level and the following parameters: sex, age, weight, body mass index, waist circumference, smoking, alcohol, systolic and diastolic blood pressure (BP), triglyceride, total cholesterol, high density lipoprotein cholesterol, creatinine, albumin and hemoglobin.

Results : The homocysteine levels was 10.5±5.9μmol/L in males, 7.3±2.6μmol/L in female. Thus it was significantly higher in males (P<0.001). After adjusting for variables that affect the homocysteine, the subjects over the age of 54 showed 10.7μmol/L (9.5, 12.0, 95% Confidence Interval), which was significantly (P=0.002) higher than the below the age of 38 groups 8.5μmol/L (7.8, 9.2, 95% CI). Non-smoking group showed 8.6μmol/L (8.4, 8.9, 95% CI), while over 28 pack-year group showed 9.6μmol/ L (9.2, 10.0, 95% CI), which was significantly (P<0.001) higher than the non-smoking groups. For the group with systolic BP over 132mmHg, it was 9.3μmol/L (8.8, 9.5, 95% CI). This was significantly (P=0.004) higher than 8.7μmol/L (8.4, 9.0, 95% CI) in the group whose systolic BP was less than 108 mmHg. The homocysteine was 10.4μmol/L (10.1, 11.7, 95% CI) for the group with creatinine over 1.0 mg/dL, which was significantly (P<0.001) higher than 7.9μmol/L (7.6, 8.2, 95% CI) in the group whose creatinine was less than 0.8 mg/dL.

Conclusion : After adjusting for variables that affect the homocysteine, significant difference in its values was found between males and females. The homocysteine was significantly increased in the group whose age, systolic BP, amount of smoking, and creatinine were higher.

초록
연구배경 : 혈중 호모시스테인 농도의 증가는 심혈관 질환의 독립적인 위험인자이다. 이에 저자들은 신체 지수, 생활 습관, 심혈관 질환의 위험 인자, 그리고 영양 상태 등이 혈중 호모시스테인의 농도와 어떤 관련이 있는지 알아보고자 하였다.

방법 : 2002년 3월부터 2003년 1월 사이 일개 대학 병원 건강증진센터를 내원한 18세 이상의 성인 6,223명(남: 3,377, 여: 2,846)을 대상으로 하여, 호모시스테인과 성별, 나이, 체중, 체질량지수, 허리 둘레, 흡연, 음주, 수축기혈압, 이완기혈압, 중성지방, 총 콜레스테롤, 고밀도 콜레스테롤, 혈중 크레아티닌, 알부민, 헤모글로빈과의 관계를 알아보았다.

결과 : 남자의 혈중 호모시스테인은 10.5±5.9μmol/L, 여자는 7.3±2.6μmol/L으로 남자에게서 유의하게 높았다(P<0.001). 호모시스테인 농도에 영향을 줄 수 있는 변수를 보정한 후, 54세 이상인 집단은 10.7μmol/L (9.5, 12.0, 95% Confidence Interval)으로 38세 이하인 집단 8.5μmol/L (7.8, 9.2, 95% CI)에 비해 유의하게 높았으며(P=0.002), 비흡연군은 8.6μmol/L (8.4, 8.9, 95% CI), 28 pack-year 이상의 흡연군은 9.6μmol/L (9.2, 10.0, 95% CI)로 흡연군에서 높았으며(P<0.001), 수축기혈압이 132 mmHg 이상인 집단이 9.3μmol/L (8.8, 9.5, 95%CI)로 수축기혈압이 108 mmHg 이하인 집단 8.7μmol/L (8.4, 9.0, 95%CI)보다 유의하게 높았으며(P=0.004), 혈중 크레아티닌이 1.0 mg/dL 이상인 집단이 10.4μmol/L (10.1, 11.7, 95% CI)로 크레아티닌이 0.8 mg/dL 이하인 집단 7.9μmol/L (7.6, 8.2, 95% CI)보다 유의하게 높았다(P<0.001).

결론 : 호모시스테인 농도에 영향을 줄 수 있는 변수를 보정한 후, 호모시스테인 농도는 남자가 여자보다 높았으며, 나이, 수축기혈압, 흡연량, 혈중 크레아티닌 농도가 높은 집단에서 혈중 호모시스테인 농도가 유의하게 증가되었다.
