Vitamin E status of Congolese children in a rural area.

The role of vitamin E in severe malnutrition is controversially discussed. In order to evaluate the vitamin E status of unselected African children the plasma tocopherol levels of 52 children from a village in the People's Republic of Congo were assessed by HPLC and related to the plasma lipid values. Although plasma concentrations of total tocopherols (mean 351.1 +/- 59.4 micrograms/dl) and alpha-tocopherol (mean 313.3 +/- 57.0 micrograms/dl) were found to be low, normal ratios of total tocopherols to total lipids (mean 0.99 +/- 0.17 mg/g) and alpha-tocopherol to total lipids (mean 0.89 +/- 0.09 mg/g) were estimated. It is concluded that plasma vitamin E levels should be related to plasma lipids if populations are monitored in which low lipid concentrations have to be expected. These data on Congolese children may be used for comparison if the vitamin E status in other agrogeographical areas of Africa or in clinically abnormal groups is investigated.
