ABSTRACT=Background: In the treatment of acute malnutrition (AM), non-response is considered a treatment failure for not meeting recovery criteria within a therapeutic window of 12-16 weeks, but this category of children is misunderstood. As current research emphasizes ways to simplify and optimize treatment protocols, non-response emerges as a new issue to enhance program efficiency.Methods: A prospective cohort study was conducted from 2019 to 2020 at two health centres in Mirriah, Niger among children aged 6-59 months with uncomplicated AM treated under the Optimising treatment for Acute Malnutrition (OptiMA) protocol. Children who did not meet recovery criteria by 12 weeks (mid-upper arm circumference (MUAC) ≥125 mm without oedema for two consecutive weeks) were classified as non-responders. Non-responders received a home visit six-months postdischarge. Logistic regression was used to analyse factors associated with NR compared with children who recovered.Of the 1,112 children enrolled, 909 recovered and 139 were NR, of which 127 (80.6%) had significant MUAC gain (mean: +9.6 mm, sd=5.1) at discharge. Girls (adjusted hazard ratio (aHR)=2.07, 95% CI 1.33-3.25), children <12 months of age (aHr=4.23, 95% CI 2.02-9.67), those with a MUAC <115 mm (aHR=11.1, 95% CI 7.23-17.4) or severe stunting (aHR=2.5, 1.38-4.83) at admission and a negative or flat MUAC trajectory between admission and week 4 (aHR = 4.66, 95% CI 2.54-9.13) were more likely to be NR. The nutritional status of NR had generally improved six months after discharge, but only 40% had achieved MUAC ≥125 mm.As efforts to expand MUAC-based programming progress, adapting exit criterion and/or providing additional food supplementation with smaller daily ration for children with risk factors discussed here may help improve programme efficiency without adding to the cost of treatment.
