The findings do not support a hypothesis that provision of SQ-LNSs to women in pregnancy and postpartum and to children from 6 to 18 mo of age would promote child growth in this Malawian study area. This trial was registered at clinicaltrials.gov as NCT01239693.

Our results do not support the hypothesis that LNS supplementation during infancy and childhood promotes length gain or prevents stunting between 6 and 18 mo of age in Malawi. This trial was registered at clinicaltrials.gov as NCT00945698.

Small‐quantity lipid‐based nutrient supplements (SQ‐LNS) are designed to enrich maternal and child diets with the objective of preventing undernutrition during the first 1,000 days. Scaling up the delivery of supplements such as SQ‐LNS hinges on understanding private demand and creatively leveraging policy‐relevant factors that might influence demand. We used longitudinal stated willingness‐to‐pay (WTP) data from contingent valuation studies that were integrated into randomized controlled nutrition trials in Ghana and Malawi to estimate private valuation of SQ‐LNS during pregnancy, postpartum, and early childhood. We found that average stated WTP for a day's supply of SQ‐LNS was more than twice as high in Ghana than Malawi, indicating that demand for SQ‐LNS (and by extension, the options for effective delivery of SQ‐LNS) may be very context specific. We also examined factors associated with WTP, including intervention group, household socioeconomic status, birth outcomes, child growth, and maternal and child morbidity. In both sites, WTP was consistently negatively associated with household food insecurity, indicating that subsidization might be needed to permit food insecure households to acquire SQ‐LNS if it is made available for purchase. In Ghana, WTP was higher among heads of household than among mothers, which may be related to control over household resources. Personal experience using SQ‐LNS was not associated with WTP in either site.

Background: It is unknown whether self-reported measures of household food insecurity change in response to food-based nutrient supplementation.Objective: We assessed the impacts of providing lipid-based nutrient supplements (LNSs) to women during pregnancy and postpartum and/or to their children on self-reported household food insecurity in Malawi [DOSE and DYAD trial in Malawi (DYAD-M)], Ghana [DYAD trial in Ghana (DYAD-G)], and Bangladesh [Rang-Din Nutrition Study (RDNS) trial].Methods: Longitudinal household food-insecurity data were collected during 3 individually randomized trials and 1 cluster-randomized trial testing the efficacy or effectiveness of LNSs (generally 118 kcal/d). Seasonally adjusted Household Food Insecurity Access Scale (HFIAS) scores were constructed for 1127 DOSE households, 732 DYAD-M households, 1109 DYAD-G households, and 3671 RDNS households. The impact of providing LNSs to women during pregnancy and the first 6 mo postpartum and/or to their children from 6 to 18–24 mo on seasonally adjusted HFIAS scores was assessed by using negative binomial models (DOSE, DYAD-M, and DYAD-G trials) and mixed-effect negative binomial models (RDNS trial).Results: In the DOSE and DYAD-G trials, seasonally adjusted HFIAS scores were not different between the LNS and non-LNS groups. In the DYAD-M trial, the average household food-insecurity scores were 14% lower (P = 0.01) in LNS households than in non-LNS households. In the RDNS trial, compared with non-LNS households, food-insecurity scores were 17% lower (P = 0.02) during pregnancy and the first 6 mo postpartum and 15% lower (P = 0.02) at 6–24 mo postpartum in LNS households.Conclusions: The daily provision of LNSs to mothers and their children throughout much of the “first 1000 d” may improve household food security in some settings, which could be viewed as an additional benefit that may accrue in households should policy makers choose to invest in LNSs to promote child growth and development. These trials were registered at clinicaltrials.gov as NCT00945698 (DOSE) NCT01239693 (DYAD-M), NCT00970866 (DYAD-G) and NCT01715038 (RDNS).

Objectives: Households' stated willingness-to-pay (WTP) for small-quantity lipid-based nutrient supplements (LNS) influence the economic viability of retail outlets for these products, and will guide public policy action when WTP falls short of LNS production/distribution costs. This presentation provides evidence on WTP for LNS products tested in the context of the International Lipid-Based Nutrient Supplements (iLiNS) Project in Malawi, Ghana and Burkina Faso. Methods: Field-based contingent valuation methods provide estimates of WTP for LNS for pregnant/lactating women (LNS-P&L) and for children 6-24 mo of age (LNS-child), and for their traditional alternatives. Experimental auctions provide incentive-compatible estimates of WTP for LNS-P&L (Ghana) and for LNS-child (Burkina Faso). Results: Average hypothetical WTP at baseline for LNS-child (one 20g sachet
