Undernutrition in early childhood causes stunted growth, cognitive delays, and anemia, with effects often magnified among children from the poorest households. Small-quantity lipid-based nutrient supplements (SQ-LNS) are effective in addressing undernutrition and improving child development. As momentum builds to scale up SQ-LNS for children aged 6-24 months in the Global South, a key concern is achieving equity in its distribution and outcomes. We performed equity analysis of individual participant data from 14 randomized controlled trials in nine countries (N=37,707 children) to assess SQ-LNS effects on child growth, development, and anemia across levels of an international wealth index. Benefits of SQ-LNS were consistent across the wealth spectrum, leading to similar improvements in child growth, development, and anemia regardless of wealth. However, such equal benefits of SQ-LNS did not erase large inequities in child growth and development between the poorest and wealthier households.
