Economic evaluations of nutrition-sensitive agriculture (NSA) interventions are scarce, limiting assessment of their potential affordability and scalability.
We conducted cost-consequence analyses of three participatory video-based interventions of fortnightly women's group meetings using: 1) NSA videos; 2) NSA and nutrition-specific videos; or 3) NSA videos with a nutrition-specific Participatory Learning and Action (PLA) cycle.
Interventions were tested in a 32-month, four-arm cluster-randomized controlled trial, UPAVAN, in Keonjhar district, Odisha, India. Impacts were evaluated in children aged 0–23 months and their mothers. We estimated program costs using data collected prospectively from expenditure records of implementing and technical partners, and societal costs using expenditure assessment of households with a child aged 0–23 months and key informant interviews. Costs were adjusted for inflation, discounted, and converted to 2019 US$⁠.
