BackgroundDespite the decreasing rate of under nutrition children in recent years overall, the negative affect in growth and development make it as a main concern in the world. Applying an available and appropriate supplementary food is a major approach in treating children with Moderate Acute Malnutrition (MAM).ObjectiveTo compare the effectiveness of a new supplementary blended flour (containing chickpea, rice, wheat and barley, named Shadameen) in combination with multivitamin/mineral supplement and nutritional counseling versus multivitamin/mineral supplement and nutritional counseling alone, in the treatment of children with MAM.MethodsThis randomized controlled trial study was conducted at Heshmatiyeh Hospital in Sabzevar city in Iran, from January 2016 to December 2016. Seventy infants, aged 9 to 24 months with MAM who were referred from urban health centers to the hospital clinic were included. They were randomly assigned to receive, for about 3 months, either multivitamin / mineral supplement and nutritional counseling alone or in combination with an extra supplementary blended food. We analyzed weight, length, weight for length Z score (WLZ), weight for age Z score (WAZ) and length for weight Z score (LAZ), along with recovery rate and adverse events among the two groups. The data were analyzed using SPSS version 16. We used statistics, Chi-square, independent t-test, and Fisher’s exact test for the analyses of primary and secondary outcomes.ResultsThe food supplementation infant’s mean weight and WLZ and WAZ were greater compared with the other group (0.81±0.29 gr and 0.55±0.33 gr, p=0.002), (0.36±0.36 and 0.02±0.52, p=0.003), (0.40±0.33 and 0.09±0.37, p=0.001). The recovery rate in the food supplemented group was significantly higher than the other group (68.4%, 31.6%, p=0.001). No adverse reactions were observed. There were no significant differences in LAZ at the end of the study between the two groups (p=0.53).ConclusionThis study showed that Shadameen in combination with multivitamin/mineral and counselling therapy can be more effective in decreasing the wasting rate of children with MAM than vitamin/mineral and counseling therapy alone.Trial registrationThe trial was registered at the Iranian Registry of Clinical Trials (http://www.irct.ir) with the Irct ID: IRCT2015040921670N1.FundingThis study was financially supported by the vice chancellor for research office, Mashhad University of Medical Sciences.
