title: [A cross-sectional study of lipid peroxide levels (plasma TBA levels) in a mass health examination].
abstract: Differences in plasma thiobarbituric acid (TBA) levels were studied by sex and age in 1,178 adults (471 males and 707 females) participating in a mass health examination conducted in a town of Kumamoto Prefecture in 1989. The relationships between plasma TBA levels and obesity, the consumption of cigarettes, alcohol, and fish, and various indices for health status derived from the data of physiological examinations were analyzed in age-groups 40-59 and 60-79 for both sexes. The prevalence of abnormal physiological findings by plasma TBA levels were further investigated. The results were as follows; 1. The highest plasma TBA levels for males were observed in the group aged 40-49, with levels gradually decreasing with age thereafter. The plasma TBA levels for females increased with age and the highest levels were obtained at age 60-69. The plasma TBA levels for males were significantly higher than for females at aged 40-49. 2. Plasma TBA levels for both sexes increased with obesity and the amount of fish consumed. 3. Plasma TBA levels in all examined groups had significant and strong positive correlations with serum total cholesterol levels and atherogenic indices, and had significant positive correlations with serum calcium and gamma-GTP levels. 4. A stepwise multiple regression analysis showed that plasma TBA levels for males were associated with serum total cholesterol, gamma-GTP, fish consumption and serum HDL-cholesterol in that order. The levels for female were associated with serum total cholesterol, body mass index, serum HDL-cholesterol and serum calcium in that order. The relationship with serum HDL-cholesterol was a negative correlation. 5. Prevalence of abnormal values of serum total cholesterol, atherogenic index and body mass index were significantly higher in the high-plasma TBA level group than in the group with median-plasma TBA level. These results suggest that plasma TBA levels may be useful as an index of undesirable lipid metabolism. Further studies should be performed to establish the significance of the relation of plasma TBA levels to fish consumption.
