Background Moderate acute malnutrition (MAM) affects 33 million children annually. Investments in formulations of corn-soy blended flours and lipid-based nutrient supplements have effectively improved MAM recovery rates. Information costs and cost-effectiveness differences are still needed. Objectives We assessed recovery and sustained recovery rates of MAM children receiving a supplementary food: ready-to-use supplementary food (RUSF), corn soy whey blend with fortified vegetable oil (CSWB w/oil), or Super Cereal Plus with amylase (SC + A) compared to Corn Soy Blend Plus with fortified vegetable oil (CSB+ w/oil). We also estimated differences in costs and cost effectiveness of each supplement. Methods In Sierra Leone, we randomly assigned 29 health centers to provide a supplement containing 550 kcal/d for ∼12 wk to 2691 children with MAM aged 6–59 mo. We calculated cost per enrollee, cost per child who recovered, and cost per child who sustained recovery each from 2 perspectives: program perspective and caregiver perspective, combined. Results Of 2653 MAM children (98.6%) with complete data, 1676 children (63%) recovered. There were no significant differences in the odds of recovery compared to CSB+ w/oil [0.83 (95% CI: 0.64–1.08) for CSWB w/oil, 1.01 (95% CI: 0.78–1.3) for SC + A, 1.05 (95% CI: 0.82–1.34) for RUSF]. The odds of sustaining recovery were significantly lower for RUSF (0.7; 95% CI 0.49–0.99) but not CSWB w/oil or SC + A [1.08 (95% CI: 0.73–1.6) and 0.96 (95% CI: 0.67–1.4), respectively] when compared to CSB+ w/oil. Costs per enrollee [US dollars (USD)/child] ranged from $105/child in RUSF to $112/child in SC + A and costs per recovered child (USD/child) ranged from $163/child in RUSF to $179/child in CSWB w/oil, with overlapping uncertainty ranges. Costs were highest per sustained recovery (USD/child), ranging from $214/child with the CSB+ w/oil to $226/child with the SC + A, with overlapping uncertainty ranges. Conclusions The 4 supplements performed similarly across recovery (but not sustained recovery) and costed measures. Analyses of posttreatment outcomes are necessary to estimate the full cost of MAM treatment. This trial was registered at clinicaltrials.gov as NCT03146897.

ObjectivesTo investigate the feasibility of eye-tracking-based testing of the speed of visual orienting in malnourished young children at rural clinics in Sierra Leone.DesignProspective dual cohort study nested in a cluster-randomised trial.Setting8 sites participating in a cluster-randomised trial of supplementary feeding for moderate acute malnutrition (MAM).ParticipantsFor the MAM cohort, all infants aged 7–11 months at the eight sites were enrolled, 138 altogether. For controls, a convenience sample of all non-malnourished infants aged 7–11 months at the same sites were eligible, 60 altogether. A sample of 30 adults at the sites also underwent eye-tracking tests as a further control.InterventionsInfants with MAM were provided with supplementary feeding.Outcome measuresThe primary outcomes were feasibility and reliability of eye-tracking-based testing of saccadic reaction time (SRT). Feasibility was assessed by the percent of successful tests in the infants. Reliability was measured with intraclass correlation coefficients (ICCs). Secondary outcomes were mean SRT based on nutritional state as well as and changes in mean SRT after supplementary feeding of MAM children.ResultsInfants exhibited consistent orienting to targets on a computer screen (>95% of valid trials). Mean SRTs had moderate stability within visits (ICCs 0.60–0.69) and across the 4-week test–retest interval (0.53) in infants; the adult control group had greater SRT stability (within visit ICC=0.92). MAM infants had a trend toward higher adjusted SRT at baseline (difference=12.4 ms, 95% CI −2 to 26.9, p=0.09) and improvement in SRT 4 weeks thereafter (difference=−14 ms, 95% CI −26.2 to −1.7, p=0.025) compared with age-matched controls.ConclusionsThe results demonstrate the feasibility of eye-tracking-based testing in a resource-poor field setting and suggest eye-tracking measures have utility in the detection of group level effects of supplementary feeding.

Examining the role of environmental enteric dysfunction (EED) in child growth requires noninvasive, field-appropriate biomarkers. Alternatives to the traditionally used lactulose:mannitol (L:M) test have been explored, but few studies have compared the L:M test to host fecal mRNA transcripts. The objectives of this study were to examine whether 1) host fecal mRNA transcripts could predict presence and severity of EED, measured using the L:M test, and 2) EED modifies the effect of specialized nutritious foods (SNFs) on recovery from moderate acute malnutrition (MAM). This substudy was nested within a cluster randomized trial comparing four SNFs in the treatment of MAM among children 6 to 59 months in Sierra Leone. EED was assessed at enrollment using the L:M test and 15 host fecal mRNA transcripts on 522 children. Recovery from MAM was defined as achieving mid-upper arm circumference ≥ 12.5 cm within 12 weeks of supplementation. Random forest classification models were used to examine prediction of presence and severity of EED by host fecal mRNA transcripts. Logistic regression was used to test for effect modification by L:M test variables including % lactulose excreted (%L). Eight host fecal mRNA transcripts (AQP9, REG3A, IFI30, DECR1, BIRC3, SELL, PIK3AP1, DEFA6) identified EED (%L ≥ 0.2) and severe EED (%L ≥ 0.45) with high sensitivity and specificity. The L:M test variables did not modify the effect of SNFs on recovery from MAM. In this study, we found host fecal mRNA transcripts that could be biomarkers of EED but did not find EED to modify the effect of SNFs on MAM treatment.

Objectives This analysis describes differences in household-level use of four specialized nutritious foods (SNFs) for treatment of moderate acute malnutrition (MAM) in children 6–59 months of age in Sierra Leone and explores whether these behaviors influenced recovery. Methods From 4/2017 to 11/2018, sub-samples of caregivers whose children were enrolled in a supplemental feeding program (SFP) for a MAM treatment study were randomly selected for in-depth interviews and in-home observations. This was a cluster-randomized trial of 2653 children with MAM in Sierra Leone evaluating cost-effectiveness of 4 SNFs: Super Cereal Plus w/amylase (SC + A), Corn-soy Blend Plus w/oil (CSB + w/oil), Corn-soy-whey Blend w/oil (CSWB w/oil), and Ready-to-Use Supplementary Food (RUSF). Caregivers received bi-weekly isocaloric distributions of 1 of the 4 SNFs until recovery or up to 12 weeks. The purpose of the in-depth interviews was to understand caregivers’ experiences with the SFP and the SNF which they received. In-home observations gathered information about observed behaviors related to SNF use over 5 consecutive days. Descriptive statistics were calculated and stratified by study arm and by outcome to explore: consumption of the SNF by the target child, sharing and selling, and diversion of other household foods. Results A total of n = 949 caregivers completed an in-depth interview. Of these, n = 323 also had an in-home observation. Observed consumption of the SNF was high in all study arms (>60%), with no discernible differences among arms. Consumption of the study food by anyone other than the beneficiary child (i.e., sharing) was similar across arms (9–12% reported, 19–27% observed), with the lowest reported and highest observed in RUSF. Very few reported giving the SNF away or selling it to others (<1%). Sharing and displacement did not differ by recovery status, but children who recovered were observed consuming the SNF more often than those who failed (82% vs. 46%). Conclusions Sharing of the SNF was common among all arms but did not affect likelihood of recovery. Ensuring adequate consumption of the SNF by the beneficiary child is critical for effectiveness. Qualitative data can expand on these findings. Funding Sources Office of Food for Peace, United States Agency for International Development.
