The study suggests that subclinical vitamin A deficiency is a problem during the third trimester of pregnancy. Serum concentration of retinol <20 microg/dL appears to indicate a deficient status, and is associated with an increased risk of preterm delivery and maternal anaemia.

Summary. Immune status during the third trimester of pregnancy was investigated in relation to maternal haemoglobin levels. The proportion of T and B lymphocytes showed a tendency to fall in anaemic women which was significant when haemoglobin levels were <8 g/dl. Immunoglobin G showed the opposite trend. There were no alterations in phytohaemag‐glutinin‐induced lymphocyte transformation in relation to haemoglobin concentration.

Macrolevel approaches to improve the availability of complementary foods. Chessa K. Lutter (pp. 83-103)Please see revised tables 1 (page 88) and 2 (page 90) on the following pages. Corrected values are shown in bold.The title of Table 3, page 92, should read: Estimated nutrient needs from complementary foods by average breastmilk intake a Page 95, the final sentence in the last full paragraph, bottom right column, should read, "On the basis of dietary intakes from complementary foods in Latin America, a level of fortification of 250 µg RE per 100 g of daily ration would meet 80% of the vitamin A needs of nonbreastfed children and all the needs of breastfed children, and it would not exceed the upper limit set by the United States for intake by breastfed children consuming the recommended daily ration [38].Pages 102-103, the year of publication in references 4, 34-39, and 41 should be 2003.
