Implication

Randomized trial identifies malnutrition thresholds affecting education in Sub-Saharan Africa, suggesting urgent nutritional interventions are needed.

Key Points

This research aims to quantify how malnutrition constrains educational outcomes in Sub-Saharan Africa by identifying critical thresholds.
Analyzed 35 Sub-Saharan African countries from 1990 to 2024 using Panel Threshold Regression and Temporal Graph Neural Networks.
Identified critical malnutrition thresholds and their effects on educational completion rates.
Conducted spatial analysis to find clusters of high vulnerability among nations.
Identified a critical malnutrition threshold at 4.37%, with effects on education intensifying above this level (β 2 = −1.847).
Below the threshold, lower secondary completion reduction was 0.31 percentage points (β 1 = −0.312).
Benefit-cost ratios for concentrated interventions ranged from 15:1 to 30:1, outperforming conventional education investments.
