Vitamin E status of Chinese population in Taiwan

Abstract

Vitamin E status of Chinese population with different age groups was studied by determining plasma vitamin E levels (PE) and hydrogen peroxide-induced erythrocyte hemolysis (HPEH). The mean PE of 99 adults, ages 23 to 78, was 1.05 +/- 0.47 mg/100 ml. There was no significant difference between sexes. PE was negatively correlated with HPEH (P less than 0.01). There was a significant positive correlation (P less than 0.01) between PE and plasma cholesterol level. The mean PE of four young men of Yami tribesmen, ages 16 to 19, was 0.60 +/- 0.10 mg/100 ml. HPEH was low. After daily supplementation of 200 mg dl-alpha-tocopheryl acetate for 16 days, PE increased 54%, but the plasma cholesterol was not affected. The mean PE of 39 elementary school children ages 12 to 13, was 0.70 +/- 0.31 mg/100 ml. The mean PE of 20 newborn infants was 0.23 +/- 0.08 mg/100 ml. HPEH was as high as 56.5 +/- 31.9% indicating a state of vitamin E deficiency. PE of total population was positively correlated with age (P less than 0.01). It was concluded that the vitamin E status of Chinese population in Taiwan was comparable to that of population groups in many other parts of the world.

Inter-relationship between serum retinol and alpha-tocopherol levels in Dhaka University students

“…High levels of serum vitamin A are found to be associated with male sex in humans (Comstock et al, 1987). Serum vitamin E levels were found to increase gradually with age (Leitner er al., 1960;Desai and Lee, 1974;Chen et al, 1977). The association of serum levels of vitamin A with age has also been reported in various studies (Abraham et al, 1974;Friedman et al, 1986;Ahmed et al, 1992).…”

Nutritional Status of Antioxidant Vitamins (A, E, and Beta-Carotene) in Elderly Japanese

“…Vitamin E The plasma level of vitamin E was found to increase gradually with age up to the seventh decade in several earlier studies (10,11). However, other studies have failed to show any relationship of age to plasma vitamin E levels (17), and some studies have even demonstrated a decline in vitamin E levels after the age of 65 (12)(13)(14)(15).…”
