Abstract

 

Objective Recent meta-analyses found treating young children with MAM using ready-to-use foods (RUF) versus fortified blended foods (FBF) resulted in higher recovery rates and weight gain. This analysis aimed to compare studies of RUF and FBF with and without dairy to determine whether the addition of dairy to these food supplements modified the comparative effectiveness and cost of treatment.

 

Methods A review of literature on the comparative effectiveness of FBF and RUF in treatment of MAM was conducted. Outcomes of recovery from MAM, weight gain and length gain were compared among study cohorts, which included FBF with dairy (FBF+), FBF without dairy (FBF−), RUF with dairy (RUF+) and RUF without dairy (RUF−). Data on recovery from MAM was pooled among the 4 supplement categories. The cost per 500 kcal of each category of food supplement was averaged among studies that reported cost data.

 

Results Among the 7 studies included, 9 RUFs were tested, of which 5 contained dairy, and 9 FBFs were tested, of which 3 contained dairy. Children treated with RUF+ had higher recovery rates compared with FBF− in 5 out of 5 study cohorts, higher weight gain in 4 out of 4, and significantly higher length gain in 1 out of 4. Children treated with RUF+ vs FBF+ had higher recovery rates in 1 out of 2 study cohorts, with no differences in weight or length gain. No differences were found in the 2 studies comparing RUF− and FBF+. Finally, children treated with RUF− had higher recovery rates compared with FBF− in 1 of 2 studies, higher weight gain in 2 out of 2, and no differences in length gain. Recovery from MAM among the 7 studies was 65% (FBF−), 79% (FBF+), 82% (RUF−), and 80% (RUF+). Four of the 7 studies included cost data; on average per 500 kcal costs were $0.15 (FBF−), $0.18 (FBF+), $0.17 (RUF−), and $0.35 (RUF+).

 

Conclusion Our results suggest that addition of dairy to FBF make it comparative in effectiveness to both RUF with and without dairy, but does not appear to be a factor between the RUF categories. RUF with dairy was twice the cost per kcal compared with the other food supplement categories. Cost-effectiveness analysis will be useful to help determine the most appropriate food supplement for treatment of MAM.
