Table 2 Characteristics of the RUSF and comparators

From: Randomised controlled trial to test the effectiveness of a locally-produced ready-to-use supplementary food (RUSF) in preventing growth faltering and improving micronutrient status for children under two years in Cambodia: a study protocol

Taste Fishy Creamy, sweet, smooth [52] Should not have a taste [53]
Preparation No 10 mins cooking No
Acceptability in Cambodia Yes Acceptable in trial [52], but not in practice [14] Yes [35]
Effectiveness in reducing malnutrition To be tested Not inferior to peanut-based RUSFs, which are the most effective in promoting linear growth and weight gain [18, 33] Improves micronutrient status but not linear growth or weight gain [5, 12, 35]
Intra-household sharing To be tested Yes [33] None noted [35]
Packaging To be determined Packaging may encourage sharing [5, 39] Looks like “medicine” thus may discourage sharing [5, 39]
Local production capacity Unknown None [5] None
Cost To be determined. Goal is <US$0.10/day Less expensive than peanut-based RUSFs if produced locally [18], but also have to consider logistics, time to treat, relapse [39] Very cheap to produce at US$0.025/daily dose [11], but also have to consider logistics
  1. *RUSF daily serving size depends on the child’s age, i.e. 6-8 m – 4 pieces, 40 g; 9-11 m – 6 pieces, 60 g; 12-17 m – 11 pieces, 110 g
