Abstract
Riboflavin status of 61 pregnant Chinese women was investigated in a longitudinal study by functional assay of the coenzyme activation of erythrocyte glutathione reductase. Maternal nonfasting venous blood was collected at 26 and 36 gestational weeks and 6 weeks postpartum. At delivery, 27 pairs of maternal and cord blood samples were also collected. Dietary intake of riboflavin was estimated by 24-hour recall method at the 26th gestational week. Judged by an activation coefficient >1.25, the prevalence of riboflavin deficiency was 31% to 45% in late pregnancy and 34% postpartum. Cord blood exhibited better riboflavin status than the maternal blood, and there was significant correlation between the two. Of all the subjects, 47.5% had a daily riboflavin intake less than the recommended dietary allowances for pregnancy. Prevalence of deficiency was highest in subjects whose diet included neither milk nor prenantal vitamin supplement. Therefore, prenatal supplementation is recommended for pregnancy in order to guarantee an adequate supply of riboflavin. © 1993 Pergamon Press Ltd. All rights reserved.
