초록

연구 배경: 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.
