Abstract: The high malnutrition rate in children under five makes this problem one of the public health problems. Various efforts have been made to reduce malnutrition in children under five, one of which is the implementation of community programs with a positive deviance approach which is considered an effective way because the solution to the problem comes from the local community. Thus, we conducted a systematic review and meta-analysis to determine the effect of interventions with a positive deviance approach to reducing under-five children’s malnutrition. Systematic searches were conducted using the following journal databases: Science Direct, Pubmed, Proquest, SAGE journal, Web of Science, and Scopus. The article was included if using an intervention design. Data analysis used Review Manager 5.4 software, random effect model, outcome mean of difference, and 95% confidence interval. There were no significant differences between the intervention and control groups on the length for age z-scores (LAZ), weight for age z-scores (WAZ), and weight for height z-scores (WHZ) indicators. There was an increase in LAZ, WAZ, and WHZ scores in the intervention group, with a greater z-score than in the control group. In conclusion, interventions with the positive deviance approach can be used as an alternative to improving the nutritional status of under-five children. However, further research is needed to determine the effective duration of interventions in improving the nutritional status of children.

Abstract: Food-based interventions to improve linear growth are most often applied in low- and middle-income countries. However, not all food interventions have been proven to be effective in promoting linear growth. This study aimed to assess the impact and effectiveness of food interventions for improving linear growth in children under five years old. This study was conducted by following the PRISMA guidelines and the data were extracted and presented following the PRISMA recommendations. Studies were identified through a literature search of the SCOPUS, Web of Science, PubMed, ScienceDirect, and ProQuest databases from 2000 to 2022. Only randomized control studies were included in this review based on the inclusion and exclusion criteria. Out of 1125 studies identified, a total of 15 studies were included in this systematic review and meta-analysis. The review result indicated that food-based intervention can help to improve linear growth (MD: 0.20, 95% CI: 0.04 to 0.35, p = 0.01) among children under five. However, there was no significant difference in changes in underweight status (MD: 0.25 CI: −0.15 to 0.64 p = 0.22) and wasting status (MD: 0.09 CI: −0.02 to 0.20 p = 0.12) between the intervention and control groups. Overall, food-based interventions were found to be helpful for improving children’s linear growth.
