A novel fortified blended flour, corn-soy blend "plus-plus," is not inferior to lipid-based ready-to-use supplementary foods for the treatment of moderate acute malnutrition in Malawian children.

ABSTRACT: Children with moderate acute malnutrition (MAM) are often treated with fortified blended flours, most commonly a corn-soy blend (CSB). However, recovery rates remain <75%, lower than the rate achieved with peanut paste-based ready-to-use supplementary foods (RUSFs). To bridge this gap, a novel CSB recipe fortified with oil and dry skim milk, "CSB++," has been developed.In this trial we compared CSB++ with 2 RUSF products for the treatment of MAM to test the hypothesis that the recovery rate achieved with CSB++ will not be >5% worse than that achieved with either RUSF.We conducted a prospective, randomized, investigator-blinded, controlled noninferiority trial involving rural Malawian children aged 6-59 mo with MAM. Children received 75 kcal CSB++ · kg(-1) · d(-1), locally produced soy RUSF, or an imported soy/whey RUSF for ?12 wk.The recovery rate for CSB++ (n = 763 of 888; 85.9%) was similar to that for soy RUSF (795 of 806, 87.7%; risk difference: -1.82%; 95% CI: -4.95%, 1.30%) and soy/whey RUSF (807 of 918, 87.9%; risk difference: -1.99%; 95% CI: -5.10%, 1.13%). On average, children who received CSB++ required 2 d longer to recover, and the rate of weight gain was less than that with either RUSF, although height gain was the same among all 3 foods studied.A novel, locally produced, fortified blended flour (CSB++) was not inferior to a locally produced soy RUSF and an imported soy/whey RUSF in facilitating recovery from MAM. The recovery rate observed for CSB++ was higher than that for any other fortified blended flour tested previously. This trial is registered at clinicaltrials.gov as NCT00998517.

Project description:BackgroundMalnutrition during pregnancy in sub-Saharan Africa is associated with poor birth outcomes.ObjectiveThis study compared maternal and offspring anthropometry for moderately malnourished pregnant women receiving ready-to-use supplemental food (RUSF), a fortified corn-soy blend (CSB+) with a daily multiple micronutrient antenatal supplement [United Nations International Multiple Micronutrient Preparation (UNIMMAP)], or standard of care comprising CSB+ and iron and folic acid (IFA).DesignA single-blind randomized controlled clinical trial was conducted in southern Malawi among 1828 pregnant women with moderate malnutrition, defined as a midupper arm circumference (MUAC) ≥20.6 and ≤23.0 cm. Women received 1 of 3 dietary treatment regimens that provided ∼900 kcal/d and 33-36 g protein/d. Maternal and infant anthropometry were followed until the child was 3 mo old.ResultsNewborns had a mean length-for-age z score of -1.3 ± 1.2 and 22% were stunted at birth. Mothers receiving RUSF had the highest weight gain during supplementation (3.4 ± 2.6, 3.0 ± 2.2, and 3.2 ± 2.4 kg for the RUSF, CSB+ with UNIMMAP, and CSB+ with IFA groups, respectively; P = 0.03). Newborn birth weights and lengths were similar across intervention groups, but the incidence of newborns with a birth weight <2.4 kg (weight-for-age z score <-2) was higher in the CSB+ with UNIMMAP group than the other groups (17%, 18%, and 24% for the CSB+ with IFA, RUSF, and CSB+ with UNIMMAP groups, respectively; P = 0.02). At birth, HIV-exposed newborns had a similar length and weight as newborns without HIV exposure, but their head circumference was smaller (34.0 ± 1.5 and 34.3 ± 1.6 cm, respectively; P = 0.02). At 3 mo of age, HIV-exposed infants had smaller weights, lengths, and head and arm circumferences than infants without HIV exposure.ConclusionsRUSF improved maternal weight gain compared with CSB+ with UNIMMAP. The large amount of food given and the modest effect on linear growth in newborns suggests that stunting in utero is unlikely to be reduced by supplemental food alone. This trial was registered at clinicaltrials.gov as NCT02120599.

Project description:BackgroundFortified blended foods (FBFs) are micronutrient-fortified food aid products containing cereals and pulses. It has been suggested to reformulate FBFs to include whey protein concentrate, use alternative commodities (e.g., sorghum and cowpea), and utilize processing methods such as extrusion to produce them. The Micronutrient Fortified Food Aid Pilot Project (MFFAPP) efficacy study was designed to test the efficacy of complementary feeding of newly formulated FBFs.ObjectivesThe aim of this study was to test the effectiveness of 5 newly formulated FBFs in combating iron deficiency anemia and vitamin A deficiency compared with traditionally prepared corn-soy blend plus (CSB+) and no intervention. A secondary aim was to determine the impact on underweight, stunting, wasting, and middle-upper arm circumference.MethodsA 20-wk, partially randomized cluster study was completed. Two age groups (aged 6-23 and 24-53 mo) with hemoglobin status <10.3 g/dL, and weight-for-height z scores >-3 were enrolled and assigned to diet groups. Biochemical and anthropometric measurements were collected at 0, 10, and 20 wk.ResultsBoth hemoglobin concentrations and anemia ORs were significantly improved in all intervention groups except for CSB+ and the no-intervention groups at week 20. Only extruded corn-soy blend 14 and the no-intervention age groups failed to significantly decrease vitamin A deficiency risk (P < 0.04). There were no consistent significant differences among groups in anthropometric outcomes.ConclusionsFBFs reformulated with sorghum, cowpea, corn, and soy significantly improved anemia and vitamin A deficiency ORs compared with week 0 and with no intervention. Although newly formulated FBFs did not significantly improve vitamin A deficiency or anemia compared with CSB+, CSB+ was the only FBF not to significantly improve these outcomes over the study duration. Our findings suggest that newly formulated sorghum- and cowpea-based FBFs are equally efficacious in improving these micronutrient outcomes. However, further FBF refinement is warranted. This trial was registered at clinicaltrials.gov as NCT02847962.
