ABSTRACT Background Vitamin A deficiency is a public health problem in sub-Saharan Africa. Pro-vitamin A biofortified (yellow) cassava has the potential to contribute significantly to improve vitamin A status, especially in populations that are difficult to reach with other strategies. Objectives The study aimed at determining the efficacy of biofortified cassava to improve vitamin A status of Nigerian preschool children. Methods An open-label randomized controlled trial was conducted in southwestern Nigeria. In total, 176 preschool children (aged 3–5 y) were randomized into 2 parallel arms comprising an experimental group (n = 88), fed foods prepared from biofortified (yellow) cassava, and a control group (n = 88), fed foods prepared from white cassava, twice a day, 6 d a week for 93 d. Results A total of 159 children completed the trial (yellow cassava group, n = 80; white cassava group, n = 79). Children consumed 221 and 74 µg/d retinol activity equivalents from intervention foods in the yellow and white cassava groups, respectively. The treatment effect on serum retinol concentrations at the end of the feeding trial was 0.06 µmol/L (95% CI: 0.004, 0.124 µmol/L), after adjustment for baseline retinol concentrations, inflammation, and asymptomatic malaria status. No significant treatment effects were detected for serum β-carotene (adjusted effect: 3.9%; 95% CI: −0.6%, 8.6%) and gut permeability (adjusted effect: 0.002; 95% CI: −0.089, 0.092), but a significant effect was detected for hemoglobin concentrations (adjusted effect: 3.08 g/L; 95% CI: 0.38, 5.78 g/L). Conclusions Daily consumption of β-carotene from biofortified cassava improved serum retinol and hemoglobin concentrations modestly in Nigerian preschool children. This study was registered with clinicaltrials.gov as NCT02627222.

Background: Prenatal supplementation with micronutrients may increase birth weight and thus improve infant health and survival in settings where infants and children are at risk of micronutrient deficiencies. Objective: To assess whether vitamin A and/or zinc supplementation given during pregnancy can improve birth weight, birth length, neonatal morbidity, or infant mortality. Methods: A double-blind, randomized controlled trial supplementing women (n = 2173) in Central Java, Indonesia throughout pregnancy with vitamin A, zinc, combined vitamin A+zinc, or placebo. Results: Out of 2173 supplemented pregnant women, 1956 neonates could be evaluated. Overall, zinc supplementation improved birth length compared to placebo or combined vitamin A+zinc (48.8 vs. 48.5 cm, p = 0.04); vitamin A supplementation improved birth length compared to placebo or combined vitamin A+zinc (48.7 vs. 48.2 cm, p = 0.04). These effects remained after adjusting for maternal height, pre-pregnancy weight, and parity. There was no effect of supplementation on birth weight, the proportion of low birth weight, neonatal morbidity, or mortality. Conclusions: Prenatal zinc or vitamin A supplementation demonstrates a small but significant effect on birth length, but supplementation with zinc, vitamin A or a combination of zinc and vitamin A, have no effect on birth weight, neonatal morbidity, or mortality.
