    Abstract:
    BACKGROUND: Iron deficiency anemia affects hundreds of millions of women and children worldwide and is associated with impaired infant outcomes. Small-quantity lipid-based nutrient supplement (LNS) have been found to reduce the prevalence of anemia and iron deficiency in some trials. OBJECTIVES: We evaluated the effectiveness of daily LNS supplementation on child anemia and micronutrient status in Madagascar within the context of an existing, scaled-up nutrition program. METHODS: We cluster-randomized 125 communities to (T0) a routine program with monthly growth monitoring and nutrition education; (T1) T0 + home visits for intensive nutrition counselling; (T2) T1 + LNS for children aged 6-18 mo; (T3) T2 + LNS for pregnant/lactating women; or (T4) T1 + parenting messages. Pregnant women and infants aged <12 mo were enrolled in 2014 and followed for 2 y. Child outcome measures included hemoglobin and anemia assessed using the HemoCue 301 system (n = 3561), and serum ferritin and soluble transferrin receptor as markers of iron status, retinol-binding protein as a marker of vitamin A status, and C-reactive protein and α-1 acid glycoprotein from a finger stick blood draw among a subsample (n = 387). We estimated mean difference using linear regression and prevalence ratios using modified Poisson regression accounting for the clustered design. All analyses were intention-to-treat. RESULTS: Children in the LNS groups (T2 and T3) had ∼40% lower prevalence of anemia and iron deficiency anemia and 25% lower prevalence of iron deficiency than children in the control group (T0) (P < 0.05 for all). There were no differences in any of the biomarkers when comparing children in the T4 group with those in T0; nor were there differences between T3 and T2. CONCLUSIONS: Our findings suggest the provision of LNS in the context of a large-scale program offers significant benefits on anemia and iron status in young children.This trial was registered at www.isrctn.com as ISRCTN14393738.
