Background: More attention is given to oxidative hypothesis which causes atherosclerosis to be recognized as inflammatory response. The relationship between serum ferritin which catalyzes lipid peroxidation and high sensitivity C-reactive protein which reflects vascular inflammation was investigated among adults in a health promotion center. Methods: The study group consisted of 297 men and women (men 86, women 211) who visited the health promotion center of a hospital in Seoul to have a health checkup from October 1, 2004 to April 1, 2005. These subjects answered the questionnares and were measured in the following; blood tests, brachial-ankle pulse wave velocity and several anthropometric measurements. Statistical analysis was performed on 111 subjects after exclusion of those subjects who were taking antihypertensive agents or antidiabetic agents, and who had acute inflammatory diseases, acute liver diseases, anemia, and who had a WBC ≥11,000×103/mm3 or a serum ferritin ≥200 ug/L or a ABI (Ankle Brachial Index) <0.9. Results: The average serum ferritin concentration of men against women was 132.57±43.12 ng/ml to 78.23±38.10 ng/ml which means that men have about 1.7 times as high concentration than women (P<0.001). Serum ferritin was significantly correlated with high sensitivity C-reactive protein (r=0.332). Even in multiple stepwise regression analysis, there was a independent relationship between serum ferritin and high sensitivity C-reactive protein (Ղ=0.138, P=0.010). When we analyzed with distinction of sex, this relationship in women was constant (Ղ=0.131, P=0.031), but serum ferritin in men just showed the trend of correlation with BMI (Ղ=9.510, P=0.059). Conclusion: There is a significant relationship between the increase of serum ferritin and high sensitivity C- reactive protein in healthy women; furthermore, studies in men need to be confirmed.

Background : Sullivan has suggested that higher incidence of coronary heart disease in men and postmenopausal women is due to higher levels of stored iron in these two groups. A few epidemiologic studies in humans have reported the association between iron stores and increased risk of cardiovascular diseases. But there is conflicting evidence regarding the relationship between iron and cardiovascular diseases. The present study evaluated the relationship between ferreting and well established cardiovascular risk factors.
Methods : There were 288 healthy subjects who visited a health promotion center of a general hospital. We collected data by means of self-reported questionnaire and measured height, weight and blood pressure. Serum ferritin, fasting blood glucose, lipid profiles, and C-reactive protein were measured at a fasting state.
Results : Mean serum ferritin values were 150.1±82.2 ng/mL in men and 61.7±38.2 ng/mL in women (P＜0.001). Serum ferritin level in current smoker was higher than in non-smoker (157.6±111.8 ng/mL versus 100.5±64.2 ng/mL, P=0.006). Serum ferritin was significantly and positively correlated with body mass index, systolic blood pressure, diastolic blood pressure, fasting blood glucose, total cholesterol and triglyceride. There was no statistical significance in age, C-reactive protein, high- density lipoprotein cholesterol and low-density lipoprotein cholesterol. In multiple regression analysis, there was association between ferritin and sex (β=-80.333, P＜0.001) and triglycerides (β=0.182, P=0.030).
Conclusion : The serum ferritin level in men is higher than in women in healthy adults. Serum ferritin is positively associated with triglycerides.
Background : A prospective study about the association between serum ferritin concentration and diabetes mellitus showed that higher risk of diabetes was found in men in higher concentration of serum ferritin. The aims of this study is to examine the association between serum ferritin concentration and the risk of diabetes mellitus in healthy Korean in hospital-based samples.
Methods : In a volunteered healthy population(n=14.782), who underwent health examination in Samsung Medical Center, from January to December 1997, serum ferritin and glucose were determined.
Results : After adjusting for age, BMI, serum triglyceride concentration, and multiple logistic regression analysis showed that those in the highest quartile had increased risk of diabetes mellitus (OR: men 2.26(95% CI 2.41-2.95, p=0.0001), women 3.03(95% CI 2.51-3.67, p=0.0001), compared with those in the lowest quartile.
Conclusion : In studied population, elevated serum ferritin concentration was associated with an increased risk of diabetes.
