Effectiveness of Financial Relief Interventions for the Prevention of Wasting in Children Up to 5 Years at Risk of Wasting and Nutritional Oedema: A Systematic Review and Meta-Analysis
Bibliographic record
Abstract
CONTEXT: Childhood malnutrition persists at alarming rates globally despite the existing preventative and therapeutic evidence-based interventions. Various financial relief strategies such as cash transfers and food vouchers have been evaluated for their effectiveness in improving access to and quality of effective interventions for improving the nutritional status of children. OBJECTIVE: In this review, we aimed to assess the impact of community-based financial relief interventions to prevent wasting among children up to 5 years at risk of wasting and nutritional oedema. DATA SOURCES: We searched 9 databases from database conception until April 13, 2023, and included 5 studies (10 articles) evaluating the impact of community-based financial relief interventions for preventing wasting among children up to 5 years. DATA EXTRACTION: Two review authors independently extracted data, and discrepancies were resolved through discussion until consensus or by consulting a third reviewer if required. DATA ANALYSIS: Three studies assessed the impact of conditional cash transfers; 2 studies evaluated unconditional cash transfers, and 1 study assessed the impact of food vouchers. We found that the impact of conditional cash transfers on the prevalence of wasting, weight-for-height z score (WHZ), weight-for-age z score, and underweight is uncertain; however these cash transfers probably reduce the prevalence of severe wasting (odds ratio [OR], 0.97; 95% CI, 0.94-1.0; 1 study; Grading of Recommendations Assessment, Development, and Evaluation [GRADE]: moderate certainty evidence). The impacts of unconditional standard cash provision on the prevalence of wasting and severe wasting are uncertain; however, unconditional double-cash provisions may reduce wasting with little or no impact on severe wasting, WHZ, and mid-upper arm circumference. For food vouchers, the evidence suggests an uncertain impact on the prevalence of wasting and severe wasting. CONCLUSIONS: Evidence on the effectiveness of community-based financial relief interventions in preventing wasting among children is scarce. Some positive impact of conditional cash transfers and unconditional double cash provision on the prevalence of wasting has been demonstrated; however, relative effectiveness, cost-effectiveness, and sustainability need further exploration. SYSTEMATIC REVIEW REGISTRATION: PROSPERO registration No. CRD42021277429.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
