A $75 nudge: can social transfers boost exclusive breastfeeding?
NCT ID NCT05665049
First seen Aug 19, 2026 · Last updated Aug 20, 2026 · Updated 1 time
Summary
This study tests whether giving new mothers a social transfer—either cash or in-kind support like diapers—can increase the number of babies exclusively breastfed for the first six months. About 300 mothers in Laos will be randomly assigned to receive no transfer, an unconditional transfer, or a transfer conditional on exclusive breastfeeding. All participants receive education on breastfeeding benefits. The study will compare breastfeeding rates at six months and also look at cost-effectiveness and child development.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Social transfers (cash or in-kind support, e.g., diapers or other goods) valued at about $75, given to mothers to support exclusive breastfeeding.
- What this could lead to
- If effective, this could point to a low-cost, scalable way to boost exclusive breastfeeding rates and improve infant health in low-resource settings.
- What could go wrong
- This is a small pilot study, so results may not apply broadly. The support is a one-time transfer, and its long-term impact on child development is uncertain.
