Vitamins A and E are essential for foetal growth, reproduction, and lactation.
In this article we report the results of a study, lead in three Eastern Algeria cities, that involved 786 post-partum women and 250 control.
Plasma levels of vitamins A, E, bêta-carotene, and some nutritional indexes were measured in both groups.
In control women, plasma retinol and bêta-carotene levels were significantly lower in Algeria than in France (retinol : 1.4 ± 0.42 vs. 1.78 ± 0.53 mumol/l ; bêta-carotene : 0.35 ± 0.261 vs. 0.94 ± 0.611).
These differences could be the consequence of different bêta-carotene and retinol intakes, In Algeria, comparisons between post-partum women and controls, showed that plasma vitamin A and bêta-carotene levels were significantly lower in post-partum than in control women.
This fact, and the lower level of retinol in control women, raises the question of supplementation for pregnant women in Algeria, at least for those with the lowest standard of living whose protein and zinc levels are also very low after delivery.
Plasma vitamin E levels and vitamin E/total lipid ratios were not different in Algeria and in France.
Vitamin E concentration was higher during pregnancy, but the vitamin E/total lipid ratio was significantly lower, which shows a relative deficiency at the end of pregnancy.
Comparisons of plasma vitamin E levels, at delivery, in primiparous and in multiparous women reveal a better tocopherol status in multiparous women. (...)
