A community-based cross-sectional study was conducted on 390 under-five malnourished children enrolled in the Rainbow Project supplementary feeding programmmes-SFPs. Dietary diversity, feeding habits and nutritional status at admission (T1) and at discharge (T2) were compared. At T1 the diet was monotonous and unbalanced, with a progressive decline in dietary diversity and anthropometric values noted with children's age growth (p < 0.001). Significant improvements were registered at T2: DDS 5.1 ± 1.1 SD vs. 8.3 ± 1.0 SD; meal frequency 3.0 ± 0.6 SD vs. 4.9 ± 0.2 SD; animal-protein consumed 62.8% vs. 90.5%; drinking water treated 41.0% vs. 97.2%. At T1, the risk of having ZMUAC < 2.5SD increased when teenage motherhood (AOR: 5.3; CI: 1.8-15.2; p = 0.002), followed by children's age >2 years (AOR: 1.9; CI: 1.1-3.5; p = 0.020). Children's age was associated with an increased risk of WAZ < 2.5 SD (AOR: 4.9; CI: 2.4-10.4; p < 0.001). When considering inadequate DDS, the variable associated was breastfeeding cessation (AOR: 12.0; CI: 4.6-31.4; p < 0.001). Rainbow's SFPs have proved effective in treating under-five malnourished children, irrespective of the severity of malnutrition.
