FANTA partner University of California, Davis (UC Davis) studied the effectiveness of lipid-based nutrient supplements (LNS) for improving nutrition among pregnant and lactating women and their children in Bangladesh. This cluster-randomized, controlled effectiveness study evaluated the impact of supplementation of the mother’s diet with LNS or iron and folic acid (IFA) on her health and nutrition, and on the health and nutrition of her newborns. It also evaluated the effect of supplementing children’s diet with LNS or multiple micronutrient powder (MNP) on their nutrition, health, and developmental outcomes through 24 months of age. Additionally, as part of the study, UC Davis evaluated the operational aspects of delivering the supplements through community-based programs, assessed willingness to pay for LNS and MNP, and the relative and absolute cost and cost-effectiveness of each approach, with particular focus on children’s linear growth.
The study population was followed up 2 years after the intervention to assess long-term impacts of the supplementation on child growth and body composition, food preferences, cognitive development, and pre-academic skills.
The following work has been completed to date:
- A report on the costs and cost-effectiveness of the interventions
- Long-term Effects of Rang-Din Nutrition (RDNS) Interventions on Maternal and Child Outcomes
- Process Evaluation of Rang-Din Nutrition Study
- A study of the acceptability of LNS and MNP among pregnant and lactating women and among infants and young children in the study area
- An assessment of women’s women adherence to LNS and IFA supplements during pregnancy and the early postpartum period
- An assessment of adherence to LNS and MNP among children 6-23 months
- A publication of the full results on health and nutrition outcomes in pregnant women and their newborns
- An executive summary on health and nutrition outcomes in pregnant women and their newborns
Additional results will be published on: the process evaluation of the intervention, the health and nutrition outcomes of the children at 24 months and at approximately 4 years, the health care expenditures of the study population, and the study population’s willingness to pay for the supplementation.
