(PO28-04-22) Effectiveness of Complementary Food Based on Foodrecipe Locally Produced in Malnutrition Prevention of Child 6–23, Katanga DRC: Randomized Controlled Trial of MASO31 Recipe
Objectives: This study aims to assess the effectiveness of the local additional food-recipe MASO 31 to increase weight gain (or z-score WHZ, WAZ, HAZ) in preventing malnutrition. The Null Hypothesis: "MASO31" recipe is not effective in preventing malnutrition or the z-score index (WHZ, WAZ, HAZ) gain averages in the two groups (intervention and control groups) are equal. The alternative Hypothesis: the "MASO31" recipe is effective in preventing malnutrition or the z-score index (WHZ, WAZ, HAZ) gain average is increased in the intervention children group than in the comparison children group.
Methods: In Kapolowe health zone, double-blind RCT is undertaken to assess the effectiveness of the MASO31 recipe to increase z-score (WHZ, WAZ, HAZ) in preventing malnutrition. P-S Power and sample size calculation software version 3.1.2. and the sample size calculation formula n=2(Zα+Z[1-β])2×SD2/d2 were used to obtain the sample size, where α=0.01, Zα=2.58, β=0.10, Z(1-β)=1.28; SD=1z-score (within each subject group), d(effect size)=0.55 z-score. So, n=2(2.58+1.28)2 ×(1)2/(0.55)2=99. Sample size with attrition rate (10%)=NR=n/(1-R)=99/(1-0,90)=110 intervention and 110 control children groups 12-20 months old. A total of 220 study children simply randomized are receiving daily 200g of MASO31 or MASO30 porridge-based. Standardized anthropometric equipment, trained investigators, and SPSS 23 are used before and will be used after implementation. A paired t-test will compare matched z-score (WHZ, WAZ, HAZ) averages within each children group. Two-sample t-test will compare the real difference of the difference of z-score (WHZ, WAZ, HAZ) gain averages in intervention and comparison children groups to reject the null hypothesis of the equality of the z-score (WHZ, WAZ, HAZ) gain averages in the two groups.
Results: The results are not yet available because it is a protocol whose study is being implemented.
Conclusions: Waiting for the end of the implementation study, we hope that this study will provide evidence about the effectiveness of local complementary food-recipe in DR Congo and serve the Health Ministry to make nutrition policy.
