Background: Multiple micronutrient deficiencies are highly prevalent among preschool children and often lead to anemia and growth faltering. Given the limited success of supplementation and health education programs, fortification of foods could be a viable and sustainable option. We report results from a community based double-masked, randomized trial among children 1-4 years evaluating the effects of micronutrients (especially of zinc and iron) delivered through fortified milk on growth, anemia and iron status markers as part of a four group study design, running two studies simultaneously.

Micronutrient deficiency is a common public health problem in India. India's history of fortification began in 1533, and in 1998, iodized salt became mandatory. According to the WHO, more than 2 billion people are deficient in vitamins and minerals, with common micronutrient deficiencies including iron, iodine, vitamin A, and vitamin D. Children, particularly those from low and middle-income families, are among the most vulnerable to these deficiencies. Fortification of food is used in many countries to improve nutrition, and this study aims to identify and analyse food fortification studies and their effectiveness in improving nutritional deficiencies in children. We searched databases such as Google Scholar and PubMed, and reviewed 10 research papers. The studies show that fortified food can play an important role in improving nutrition-related deficiencies in children. The food vehicles used for fortification are cereals, oils and salts, and other options such as school meals. Multi-micronutrient foods fortified with iron, iodine, vitamin A, and vitamin D are strongly associated with health benefits. The studies show that iron increases haemoglobin levels, thereby decreasing the prevalence of anaemia, while iodine supplementation improves cognition and zinc has a positive effect on anthropometry and common morbidity symptoms. Existing government nutrition programs, especially those targeting children, are a good approach for implementing food fortification.

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. A pragmatic cluster-randomized controlled trial. 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. Children aged 6-23 months. Overall prevalence of anaemia in the sample was high: 90 %. HFF provided a modest but statistically significant Hb change v. no ...
BACKGROUND: Vitamin and mineral deficiencies, particularly those of iron, vitamin A and zinc, affect more than two billion people worldwide. Young children are highly vulnerable because of rapid growth and inadequate dietary practices. Micronutrient powders (MNP) are single-dose packets containing multiple vitamins and minerals in powder form that can be sprinkled onto any semi-solid food.The use of MNP for home or point-of-use fortification of complementary foods has been proposed as an intervention for improving micronutrient intake in children under two years of age. OBJECTIVES: To assess the effects and safety of home (point-of-use) fortification of foods with multiple micronutrient powders on nutritional, health and developmental outcomes in children under two years of age. SEARCH STRATEGY: We searched the following databases in February 2011: Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library), MEDLINE (1948 to week 2 February 2011), EMBASE (1980 to Week 6 2011), CINAHL (1937 to current), CPCI-S (1990 to 19 February 2011), Science Citation Index (1970 to 19 February 2011), African Index Medicus (searched 23 February 2011), POPLINE (searched 21 February 2011), ClinicalTrials.gov (searched 23 February 2011), mRCT (searched 23 February 2011), and World Health Organization International Clinical Trials Registry Platform (ICTRP) (searched 23 February 2011). We also contacted relevant organisations (25 January 2011) for the identification of ongoing and unpublished studies. SELECTION CRITERIA: We included randomised and quasi-randomised trials with either individual or cluster randomisation. Participants were children under the age of two years at the time of intervention, with no specific health problems. The intervention was consumption of food fortified at the point of use with multiple micronutrient powders formulated with at least iron, zinc and vitamin A compared with placebo, no intervention or the use of iron containing supplements, which is the standard practice. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed the eligibility of studies against the inclusion criteria, extracted data from included studies and assessed the risk of bias of the included studies. MAIN RESULTS: We included eight trials (3748 participants) conducted in low income countries in Asia, Africa and the Caribbean, where anaemia is a public health problem. The interventions lasted between two and 12 months and the powder formulations contained between five and 15 nutrients. Six trials compared the use of MNP versus no intervention or a placebo and the other two compared the use of MNP versus daily iron drops. Most of the included trials were assessed as at low risk of bias.Home fortification with MNP reduced anaemia by 31% (six trials, RR 0.69; 95% CI 0.60 to 0.78) and iron deficiency by 51% (four trials, RR 0.49; 95% CI 0.35 to 0.67) in infants and young children when compared with no intervention or placebo, but we did not find an effect on growth.In comparison with daily iron supplementation, the use of MNP produced similar results on anaemia (one trial, RR 0.89; 95% CI 0.58 to 1.39) and haemoglobin concentrations (two trials, MD -2.36 g/L; 95% CI -10.30 to 5.58); however, given the limited amount of data these results should be interpreted cautiously.No deaths were reported in the trials and information on side effects and morbidity, including malaria, was scarce.It seems that the use of MNP is efficacious among infants and young children six to 23 months of age living in settings with different prevalences of anaemia and malaria endemicity, regardless of whether the intervention lasts two, six or 12 months or whether recipients are male or female. AUTHORS' CONCLUSIONS: Home fortification of foods with multiple micronutrient powders is an effective intervention to reduce anaemia and iron deficiency in children six months to 23 months of age. The provision of MNP is better than no intervention or placebo and possibly comparable to commonly used daily iron supplementation. The benefits of this intervention as a child survival strategy or on developmental outcomes are unclear. Data on effects on malaria outcomes are lacking and further investigation of morbidity outcomes is needed. The micronutrient powders containing multiple nutrients are well accepted but adherence is variable and in some cases comparable to that achieved in infants and young children receiving standard iron supplements as drops or syrups.

Iron deficiency constitutes a major public health problem in Morocco, mainly among women and children. The aim of our paper is to assess the efficacy of consumption of multiple micronutrients (MMN) fortified milk on iron status of Moroccan schoolchildren living in rural region. Children ( = 195), aged 7 to 9 y, were recruited from schools and divided into two groups: the nonfortified group (NFG) received daily a nonfortified Ultra-High-Temperature (UHT) milk and the fortified group received (FG) daily UHT milk fortified with multiple micronutrients including iron sulfate. Blood samples were collected at baseline (T0) and after 9 months (T9). Hemoglobin (Hb) was measured in situ by Hemocue device; ferritin and C Reactive Protein were assessed in serum using ELISA and nephelometry techniques, respectively. Results were considered significant when the value was <0.05. At T9 FG showed a reduction of iron deficiency from 50.9% to 37.2% ( = 0.037). Despite the low prevalence of iron deficiency anemia (1.9%); more than 50% of children in our sample suffered from iron deficiency at baseline. The consumption of fortified milk reduced the prevalence of iron deficiency by 27% in schoolchildren living in high altitude rural region of Morocco. Clinical Trial Registration. Our study is registered in the Pan African Clinical Trial Registry with the identification number PACTR201410000896410.

Republic Working Group 8 BACKGROUND/OBJECTIVES: To combat iron and other micronutrient deficiencies, the Ministry of Health of the Kyrgyz Republic launched a regional Infant and Young Child Nutrition (IYCN) program in 2009, which included promotion of home fortification with micronutrient powder (MNP) containing iron (12.5 mg elemental iron), vitamin A (300 mg) and other micronutrients. Every 2 months children aged 6-24 months were provided 30 sachets to be taken on a flexible schedule. The objective was to assess biochemical indicators of iron and vitamin A status among children aged 6-24 months at the baseline and follow-up surveys. SUBJECTS/METHODS: Cross-sectional representative cluster surveys were conducted in 2008 (n ¼ 571 children) and 2010 (n ¼ 541). Data collected included measurement of hemoglobin, serum ferritin, soluble transferrin receptor (sTfR), retinol-binding protein, C-reactive protein (CRP) and a 1-glycoprotein acid (AGP). RESULTS: Among all children, declines were observed in the prevalence of: anemia, 50.6% versus 43.8% (P ¼ 0.05); total iron deficiency (either low ferritin or high sTfR), 77.3% versus 63.7% (Po0.01); and iron deficiency anemia, 45.5% versus 33.4% (Po0.01). Among children without inflammation as measured by CRP and AGP, similar declines were observed, but only declines in total iron deficiency and iron deficiency anemia reached statistical significance. Among all children and those without inflammation, the prevalence of vitamin A deficiency remained the same. CONCLUSIONS: One year after the introduction of home fortification with MNP, within a larger IYCN program, the prevalence of anemia, iron deficiency and iron deficiency anemia declined, but vitamin A deficiency remained unchanged.

Background: The rates of anemia in children in southern Israel are high despite the current prevention strategy. A daily dose of "Sprinkles" (SuppleForte TM , Heinz, Canada), a micronutrient home supplementation, was proven effective for the treatment of anemia worldwide. Objectives: To assess the efficacy of Sprinkles, a novel supplementation formulation, in the primary prevention of anemia in infants who have free access to health care services. methods: A two-arm open-labeled cluster randomized controlled clinical trial was performed in 6 month old Bedouin and Jewish infants. The Sprinkles arm received sachets with iron, vitamins A and C, folic acid and zinc, and the control arm received standard treatment (liquid iron and vitamins A and D). The infants were from families attending Mother and Child Health clinics during 2005-2007. Intervention and follow-up were conducted for babies aged 6-12 months. Health outcomes (hematologic and nutritional indicators, growth parameters, morbidity rates) were evaluated at 12 and 18 months. results: The final study population numbered 621 infants (328 Bedouin and 293 Jewish); of the parents approached 88.5% agreed to participate. Hemoglobin > 11 g/dl was found in 55% of Bedouin and 40% of Jewish infants (P < 0.01). Bedouin infants had significantly lower serum concentration of iron, folic acid and zinc. All background, hematologic and micronutrient indicators were similar in the two study arms except for a slightly but not clinically significant difference in hemoglobin and hematocrit levels in Bedouins. conclusions: Our findings indicate the need to improve the micronutrient status of infants living in the Negev. A cluster randomized trial in MCH clinics is a feasible option.

Anaemia affects approximately 69 % of Indian children aged 6–12 months, with Fe deficiency (ID) being a common cause. The effectiveness of micronutrient-fortified infant cereal in improving Fe status and neurodevelopment was evaluated in non-anaemic and mildly anaemic Indian infants. An intervention group (IC) enrolled at age 6 months consumed 50 g/d of rice-based cereal providing 3·75 mg Fe/d as ferrous fumarate for 6 months (n 80) and was compared with a matched static cross-sectional control group (CG) without intervention enrolled at age 12 months (n 80). Mean Hb was higher in IC (118·1 (sd 10·2) g/l) v. CG (109·5 (sd 16·4) g/l) at age 12 months (adjusted mean difference: 9·7 g/l; 95 % CI 5·1, 14·3; P < 0·001), while geometric mean serum ferritin tended to be higher (27·0 (–1 sd 13·4, +1 sd 54·4) v. 20·3 (–1 sd 7·5, +1 sd 55·0) ng/ml); P = 0·085) and soluble transferrin receptor was lower (1·70 (–1 sd 1·19, +1 sd 2·43) v. 2·07 (–1 sd 1·29, +1 sd 3·33) mg/l; P = 0·014).
