Malian children with moderate acute malnutrition who are treated with lipid-based dietary supplements have greater weight gains and recovery rates than those treated with locally produced cereal-legume products: a community-based, cluster-randomized trial.

BACKGROUND: Moderate acute malnutrition (MAM), defined as weight-for-length z score between -3 and -2 or midupper arm circumference between 11.5 and 12.5 cm, affects ∼33 million children aged <5 y worldwide. OBJECTIVE: The objective was to compare the effects of 4 dietary supplements for the treatment of MAM. DESIGN: Twelve community health centers in rural Mali were randomly assigned to provide to 1264 MAM children aged 6-35 mo one of 4 dietary supplements containing ∼500 kcal/d for 12 wk: 1) ready-to-use, lipid-based supplementary food (RUSF); 2) special corn-soy blend (CSB++); 3) locally processed, fortified flour (Misola); or 4) locally milled flours plus oil, sugar, and micronutrient powder (LMF). RESULTS: In total, 1178 children (93.2%) completed the study. The adjusted mean (95% CI) change in weight (kg) from baseline was greater with RUSF than with the locally processed blends and was intermediate with CSB++ [1.16 (1.08, 1.24) for RUSF, 1.04 (0.96, 1.13) for CSB++, 0.91 (0.82, 0.99) for Misola, and 0.83 (0.74, 0.92) for LMF; P < 0.001]. For length change, RUSF and CSB++ differed significantly from LMF. Sustained recovery rates were higher with RUSF (73%) than with Misola (61%) and LMF (58%), P < 0.0001; CSB++ recovery rates (68%) did not differ from any of the other groups. CONCLUSIONS: RUSF was more effective, but more costly, than other dietary supplements for the treatment of MAM; CSB++ yielded intermediate results. The benefits of treatment should be considered in relation to product costs and availability.

An efficacy study on alleviating micronutrient deficiencies through a multiple micronutrient fortified salt in children in South India.

BACKGROUND: Multiple micronutrient deficiencies are prevalent in India. OBJECTIVE: The study aims to establish the efficacy of multi-micronutrient fortified salt in addressing multiple micronutrient deficiencies among children compared to nutrition education and no intervention in Tamilnadu. METHODS: The study employed a community based randomized controlled trial designed to study the impact of multiple micronutrient salt (micronutrient group) in comparison with nutrition education (education group) and no intervention (control group) on haemoglobin, serum ferritin, soluble transferrin receptor, body iron stores, serum retinol and urinary iodine outcomes over a period of 8 months. The fortified salt contained iron, iodine, vitamin A, vitamin B12 and folic acid. All the children were dewormed at baseline and at the end of the study just before the biochemical measurements. RESULTS: There was a significant improvement in most biochemical parameters studied in the micronutrient group when compared with the control group whereas this was not seen between the education and control. Over 8 months, in the micronutrient group, hemoglobin increased by 0.52 g/dL, retinol by 8.56 µg/dL, ferritin by 10.8 µg/L, body iron stores by 1.27 mg and the decrease in the prevalence of retinol deficiency was from 51.6% to 28.1%, anaemia from 46.0% to 32.6%, iron deficiency from 66.9% to 51.3% and iron deficiency anaemia from 35.2% to 31.0%, while the prevalence of all these deficiencies increased or the changes were not significant in the other two groups. CONCLUSIONS: Multiple micronutrient fortified salt was able to improve iron and vitamin A status, whereas this was not seen in the nutrition education group.

Prevalence and public health relevance of micronutrient deficiencies and undernutrition in pre-school children and women of reproductive age in Côte d'Ivoire, West Africa.

OBJECTIVE: To provide nationally representative data on the prevalence of anaemia, vitamin A and Fe deficiencies among pre-school age children (pre-SAC) and non-pregnant women of reproductive age (WRA), and on vitamin B12 and folate deficiencies in WRA, and the influence of inflammation on their interpretation. DESIGN: A cross-sectional survey to measure anthropometry, malaria parasitaemia and micronutrient status. Specifically, blood samples were analysed for Hb, plasma ferritin, soluble transferrin receptors, C-reactive protein, α1-acid glycoprotein, retinol-binding protein, vitamin B12 and folate. SETTING: Côte d'Ivoire in 2007. SUBJECTS: Nine hundred and twenty-eight WRA and 879 pre-SAC. RESULTS: In WRA, prevalence of Plasmodium parasitaemia (5 %) was low, but inflammation (34 %) was higher. Anaemia was a severe public health problem and prevalence differed by residency and eco-region. Inflammation-adjusted Fe deficiency was highest in urban areas (20 %). Nationally, folate deficiency was 86 %, higher in urban areas and varied by eco-region. Prevalence of vitamin B12 deficiency was low but higher in the rural areas and the north. Inflammation-adjusted vitamin A deficiency was very low (1 %). In pre-SAC, prevalence of inflammation (67 %) and Plasmodium parasites (25 %) was high; the latter was associated with poverty, rural residency and higher ferritin concentrations. Anaemia was classified as a severe public health problem (72 %), and was higher in rural areas (76 %) and the north (87 %). A quarter of pre-SAC suffered from vitamin A deficiency (inflammation-adjusted) and prevalence of undernutrition was high. CONCLUSIONS: Prevalence of inflammation, Plasmodium parasitaemia and micronutrient deficiencies were high in Côte d'Ivoire, particularly in pre-SAC. Nutritional interventions should be accompanied by strategies to reduce exposure to infections.

Fermented soyabean and vitamin C-rich fruit: a possibility to circumvent the further decrease of iron status among iron-deficient pregnant women in Indonesia.

OBJECTIVE: Increasing the consumption of Fe-rich foods and thus improving Fe bioavailability without significantly increasing diet cost is the most sustainable intervention for improving Fe intake. We assessed the effect of supplementary food consisting of fermented soyabean (tempeh) and vitamin C-rich fruit consumed during pregnancy on maternal iron deficiency (ID). DESIGN: Pregnant women were randomly allocated by village into optimized diet and control groups. Supplementary food was given 6 d/week at home. The average weekly food provided comprised 600 g of tempeh, 30 g of meat, 350 g of guava, 300 g of papaya and 100 g of orange. Hb, ferritin and transferrin receptor (TfR) concentrations were measured at 12-20 and at 32-36 weeks of gestation. SETTING: Thirty-nine villages in Indonesia. SUBJECTS: Pregnant women (12-20 weeks of gestation, n 252). RESULTS: At baseline, mean Hb, ferritin and TfR concentrations and body Fe concentration were within the normal range and did not differ between groups. At near term, mean Hb, ferritin and body Fe decreased, whereas mean TfR increased significantly in both groups. The mean changes in Fe status were similar in both groups. In Fe-deficient women, consumption of an optimized diet was associated with smaller decreases in Hb (1·02 (95% CI 0·98, 1·07) g/l; P = 0·058), ferritin (1·42 (95% CI 1·16, 1·75) µg/l; P = 0·046) and body Fe (2·57 (95% CI 1·71, 3·43) mg/kg; P = 0·073) concentrations, compared with a state of no intervention. Fe-deficient women at baseline benefited more from supplementary food compared with Fe-replete women. CONCLUSIONS: Daily supplementary food containing tempeh and vitamin C-rich fruits during pregnancy might have positive effects on maternal ID.

Effect of daily or weekly multiple-micronutrient and iron foodlike tablets on body iron stores of Indonesian infants aged 6-12 mo: a double-blind, randomized, placebo-controlled trial.

BACKGROUND: There is still uncertainty about the best procedure to alleviate iron deficiency. Additionally more reliable methods are needed to assess the effect of iron intervention. OBJECTIVE: We examined the efficacy of daily iron (10 mg), daily and weekly multiple-micronutrient supplementation (10 and 20 mg Fe, respectively) in improving body iron stores of Indonesian infants. DESIGN: Infants aged 6-12 mo were randomly allocated to 1 of 4 groups: daily multiple-micronutrients (DMM) foodlike tablets (foodLETs), weekly multiple-micronutrient (WMM) foodLETs, daily iron (DI) foodLETs, or daily placebo. Hemoglobin, ferritin, transferrin receptors, and C-reactive protein data were obtained at baseline and 23 wk. RESULTS: Body iron estimated from the ratio of transferrin receptors to ferritin was analyzed for 244 infants. At baseline, mean iron stores (0.5 +/- 4.1 mg/kg) did not differ among the groups, and 45.5% infants had deficits in tissue iron (body iron < 0). At week 23, the group DI had the highest increment in mean body iron (4.0 mg/kg), followed by the DMM group (2.3 mg/kg; P < 0.001 for both). The iron stores in the WMM group did not change, whereas the mean body iron declined in the daily placebo group (-2.2 mg/kg; P < 0.001). Compared with the daily placebo group, the DMM group gained 4.55 mg Fe/kg, the DI group gained 6.23 mg Fe/kg (both P < 0.001), and the WMM group gained 2.54 mg Fe/kg (P = 0.001). CONCLUSIONS: When compliance can be ensured, DI and DMM foodLETs are efficacious in improving and WMM is efficacious in maintaining iron stores among Indonesian infants.

Effect of vitamin A supplementation with BCG vaccine at birth on vitamin A status at 6 wk and 4 mo of age.

BACKGROUND: The effect of vitamin A supplementation (VAS) at birth on subsequent vitamin A status has not been studied. OBJECTIVE: The objective was to study the effect of 50,000 IU vitamin A administered with BCG vaccine at birth on vitamin A status in both sexes. DESIGN: Within a randomized placebo-controlled trial of VAS, we obtained blood from 614 children at 6 wk of age and from 369 mother-infant pairs at 4 mo of age. We assessed vitamin A status on the basis of serum retinol-binding protein (RBP) and measured serum C-reactive protein to monitor for concurrent infections. RESULTS: RBP concentrations indicated vitamin A deficiency in 32% of the children at age 6 wk and in 16% at age 4 mo. VAS was not associated with higher RBP concentrations overall or in either sex. However, the effect of VAS varied with maternal education (P for interaction = 0.004): At age 6 wk, VAS was associated with higher (9%; 95% CI: 2, 17%) RBP concentrations in children of noneducated mothers but not in children of educated mothers. Overall, RBP concentrations increased between 6 wk and 4 mo of age. The increase correlated inversely with the number of diphtheria-tetanus-pertussis (DTP) vaccines received in the interval (P = 0.009), particularly in girls (P for interaction = 0.01) and in vitamin A recipients (P = 0.01). CONCLUSIONS: Overall, VAS at birth had no effect on vitamin A status. However VAS may temporarily improve vitamin A status in the subgroup of children of noneducated mothers. In vitamin A recipients, subsequent DTP vaccines affected vitamin A status negatively. The main trial was registered at clinicaltrials.gov as NCT00168597.
