Abstract

Plasma concentrations of α-tocopherol and retinol were measured in 17 obese children (10 boys and 7 girls, age: 13.9 ± 0.3 y, mean ± s.e.m.) and related to anthropometric indices and fasting plasma insulin concentrations. Body weight was 89.0 ± 5.3 kg, relative body weight 165 ± 6%, body fat content 38.9 ± 1.2% and body mass index 32.3 ± 1.3 kg/m2. Plasma α-tocopherol, retinol and insulin concentrations were 18.5 ± 1.6 μmol/l, 2.0 ± 0.2 μmol/l and 17.2 ± 1.6 mU/l, respectively. Neither α-tocopherol nor retinol concentrations were related to age. Plasma retinol concentrations were positively correlated to weights (r = 0.60, P= 0.01) and heights (r = 0.65, P < 0.01), but not to body fat contents. In contrast, plasma a-tocopherol concentrations were not related to weights and heights, but a significant inverse relation was seen to body fat contents (r = -0.49, P = 0.04). Pasting plasma insulin concentrations did not correlate with plasma retinol values, but were inversely related to plasma cc-tocopherol concentrations (r = -0.53, P = 0.02) and α-tocopherol:cholesterol + triglyceride ratios (r = -0.57, P = 0.01). These results indicate that the factors influencing the availability of retinol and α-tocopherol in obese children may be different.
