Abstract

The serum tocopherol levels were determined on 923 workers (18–62 years of age) from the textile, chemical and metallurgical industries. Tocopherol levels varied between 0,20 and 1,86 mg per 100 ml serum, the mean value being 0,77 ± 0,01 mg per 100 ml, but in 148 subjects (16%) concentrations under 0,5 mg per 100 ml were found. For women the average was significantly (p < 0,05) lower than that for men (0,75 ± 0,02 compared to 0,79 ± 0,01) and the prevalence of levels below 0,5 mg per 100 ml greater (18,4% compared to 12,6%). Independent of sex the serum tocopherol level increased with age (from 0,59 ± 0,02 under 26 years, to 0,87 ± 0,05 mg per 100 ml for the group over 55 years, p < 0,001).

By grouping the persons according to the tocopherol levels (A = up to 0,5 mg per 100 ml; B = 0,51–1,0 and C = over 1,0 mg per 100 ml) and by calculating for each group the average values of the daily fat intake (supplied especially by sunflower oil) a relationship was found between the two series of values, but overall this did not reach statistical significance.
