BACKGROUND: Economic evaluations of nutrition-sensitive agriculture (NSA) interventions are scarce, limiting assessment of their potential affordability and scalability. OBJECTIVE: 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. METHODS: 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${\$}$. RESULTS: Total program costs of each intervention ranged from US${\$}$272,121 to US${\$}$386,907. Program costs per pregnant woman or mother of a child aged 0-23 months were US${\$}$62 for NSA videos, US${\$}$84 for NSA and nutrition-specific videos, and US${\$}$78 for NSA videos with PLA (societal costs: US${\$}$125, US${\$}$143, and US${\$}$122 respectively). Substantial shares of total costs constituted developing and delivering the videos and PLA (52-69%) and quality assurance (25-41%). Relative to control, children's minimum dietary diversity was higher in the intervention incorporating nutrition-specific videos (adjusted relative risk [95% CI] 1.19 [1.03, 1.37]) and PLA (1.27 [1.11, 1.46]). Relative to control, mothers' minimum dietary diversity was higher in NSA video (1.21 [1.01, 1.45]), and NSA with PLA (1.30 [1.10, 1.53]) interventions. CONCLUSION: NSA videos with PLA can increase both maternal and child dietary diversity and has the lowest cost per unit increase in diet diversity. Building on investments made in developing UPAVAN, cost-efficiency at scale could be increased with less intensive monitoring, reduced start-up costs, and integration within existing government programs.Trial registration: ISRCTN65922679.
