Relationships between serum thiobarbituric acid (TBA) level and smoking, alcohol drinking, differences in food intake with alcohol drinking, serum vitamin C (VC) and E (VE) were studied in 283 non-treated men (aged 20-69 years) who visited a human dock conducted in an urban area of Hyogo prefecture in 1989-1991 (annually May-July). The results were as follows: 1. An effect of smoking on serum TBA level was not observed. 2. The subjects were divided into three groups according to weekly sake intake levels, i.e., non-drinkers including ex-drinkers (ND), mild drinkers (MD, weekly sake intake: < or = 1260 ml), and heavy drinkers (HD, > 1260 ml). The serum TBA level of HD, but not of MD, was significantly higher than that of ND. 3. Serum TBA level had significant positive correlations with age, GPT, gamma-GTP, TC (total cholesterol), TG (triglycerides), PL (phospholipids), total serum lipids (TLP, i.e., TC+TG+PL), VE, eicosapentaenoic acid (EPA, C20:5) and docosahexaenoic acid (DHA, C22:6), but had no significant correlations with VC and VE/TLP. 4. The subjects (N+M) D, which included ND and MD, and those of HD were divided respectively into three groups according to weekly food intake levels, i.e., non-intake group (NF), low frequent intake group (LF, 1-3 days/week), and high frequent intake group (HF, > or = 4 days/week). The fish intake level of HD was significantly higher than that of (N+M) D, while the intake levels of vegetables, fruits and soft drinks of HD were significantly lower than those of (N+M) D. 5. Serum TBA level, GOT, GPT, gamma-GTP, TG, PL, TLP, VE, EPA and DHA of HD were significantly higher than those of (N+M) D. On the other hand, VC of HD was significantly lower than that of (N+M) D. 6. When the subjects of (N+M) D were divided into three groups according to weekly fish intake levels as mentioned above, serum TBA level, EPA and DHA of HF in (N+M) D were significantly higher than those of NF in (N+M) D. 7. Serum TBA level of HD in non-fish intake group was significantly higher than that of (N+M) D in the same group. These results suggest that increased serum TBA level in HD is closely related to the increased intake frequency of fish in addition to the effect of alcohol drinking.(ABSTRACT TRUNCATED AT 250 WORDS)
