Abstract

The purpose of this study was to investigate the implications of dietary intake and the level of serum micronutrients (Se, Mn, Cu, Zn), lipid peroxidation, and antioxidant capacity in Korean women with cervical intraepithelial neoplasia (CIN). From October 2002 to March 2003, 50 patients diagnosed with CIN (confirmed with colposcopy directed biopsy) and 50 patients without any cervical disease as the control group were enrolled in the study at the Department of Gynecology Cancer Center at Samsung Cheil Hospital. Animal fat intake in CIN group was significantly higher than that of the control group, but plant protein intake in the CIN group was significantly lower than that of the Control group. Energy and zink intakes were similar in the two groups. The serum concentration of antioxidant minerals in the CIN group were not signifi-cantly different from the control group. The total radical trapping antioxidant potential concentration of plasma was sig-nificantly lower in the CIN group (1.12 mM) than in the control group (1.25 mM)(p < 0.05). But MDA (malondialde-hyde) of serum was significantly higher in the CIN group (7.60 mM) than in the control group (4.99 mM)(p < 0.005). The serum selenium concentration of the control group showed significant positive correlation with the MDA level (r = 0.311). These findings are suggestive of protective roles for healthy dietary habit including increasing antioxidant nut-rients and decreasing intake of fat.
