The WHO recommendation of home fortification of foods with multiple-micronutrient powders in children under 2 years of age and its effectiveness on anaemia and weight: a pragmatic cluster-randomized controlled trial.

OBJECTIVE: To assess under real community settings the effectiveness of the WHO strategy of home fortification of foods (HFF) with multiple-micronutrient powders on Hb change, anaemia and weight in children. DESIGN: A pragmatic cluster-randomized controlled trial. SETTING: Forty villages in the Nioro Circle in Mali and 722 children aged 6-23 months were randomized to the intervention or control group. The intervention consisted of a daily dose of multiple-micronutrient powder for 3 months; in the control group, no supplement was given. In both groups, mothers received group education on child complementary feeding. Changes in weight, Hb concentration and anaemia were assessed as primary outcomes at baseline and 3 months. The HFF effect was determined using regression analyses and quantile regression with standard errors taking account of the cluster design. SUBJECTS: Children aged 6-23 months. RESULTS: Overall prevalence of anaemia in the sample was high: 90 %. HFF provided a modest but statistically significant Hb change v. no intervention (0·50 v. 0·09 g/dl, P=0·023). Prevalence of anaemia changed little: 91·3-85·8 % (P=0·04) in the intervention group v. 88·1-87·5 % % (P=0·86) in the control group. Proportion of severe anaemia was reduced by 84 % (from 9·8 to 1·6 %) in the intervention group, but increased in the control group (from 8·5 to 10·8 %). No effect was observed on weight. CONCLUSIONS: The WHO HFF strategy to fight anaemia showed a modest change on Hb concentration and significantly reduced the rate of severe anaemia.

Relapses from acute malnutrition and related factors in a community-based management programme in Burkina Faso.

Community-based management of acute malnutrition (CMAM) is effective in treating acute malnutrition. However, post-discharge follow-up often lacks. We aimed at assessing the relapse rate and the associated factors in a CMAM programme in Burkina Faso. Discharged children from the community nutrition centre were requested to return at least every 3 months for follow-up. The data of recovered children (weight-for-height z-score ≥-2) who were discharged between July 2010 and June 2011 were collected in 45 villages, randomly selected out of 210 in January 2012. Sociodemographic data, economic variables, information on household food availability and the child's food consumption in the last 24 h were collected from the parents. A multivariate Cox proportional hazards regression was used to identify the factors associated to relapse. Of the 637 children, 14 (2.2%) died and 218 (34.2%) were lost to follow-up. The relapse rate [95% confidence interval] among the children who returned for follow-up was 15.4 [11.8-19.0] per 100 children-years. The associated factors to relapses in multivariate Cox regression model were mid-upper arm circumference (MUAC) at discharge below 125 mm, no oil/fat consumption during the last 24 h and incomplete vaccination. To limit relapses, CMAM programmes should avoid premature discharge before a MUAC of at least 125 mm. Nutrition education should emphasize fat/oil as inexpensive energy source for children. Promoting immunization is essential to promote child growth. Periodic monitoring of discharged children should be organized to detect earlier those who are at risk of relapse. The relapse rate should be a CMAM effectiveness indicator.

When to start supplementary iron to prevent iron deficiency in early childhood in sub-Saharan Africa setting.

BACKGROUND: To study the efficacy of oral ferrous fumarate, an inexpensive, readily available preparation on iron deficiency in infants in Africa. PROCEDURE: Four months old (group 1, n = 252) and 6-18 months old (group 2, n = 360) healthy infants attending four primary health care centers (PHC) for vaccination/well-child visits in Benin were studied. Ninety-six pregnant women (PW) over 36 weeks gestational age attending the same PHC during the study period were also studied. Infants were offered 2 months supplementation with oral powdered generic ferrous fumarate (GFF), that is, 5 mg/kg/day of elemental iron, given twice and were reevaluated 2 months later for hematological indices. The prevalence of anemia and iron deficiency among pregnant women was assessed using hematological indices and transferrin saturation. RESULTS: The prevalence of anemia was 42.0%, 61.9%, and 37.5% in groups 1, 2, and PW, respectively. All anemic PW were iron deficient. Hemoglobin level shifted towards high values after supplementation. In addition, 24 infants from group 1 whose mothers interrupted the treatment, showed a significant decrease in hemoglobin level values, and similar improvement after two additional months of supplementation. CONCLUSION: Programs to prevent iron deficiency in Africa should utilize inexpensive preparations, start during pregnancy, continue in infants at 3 months of age and address problems of noncompliance.
