The Cost of Home Delivery Schemes for Lipid-based Nutrient Supplement Products: A Policy Experiment from Rural Malawi

Stephen Vosti, Jacob Humber, Thokozani Phiri, Per Ashorn, Ken Maleta & Kathryn Dewey · European Journal of Nutrition & Food Safety · 2015

Objectives: Public policy makers may play a role in promoting products demonstrated to be efficacious.  Home delivery reduces households’ out-of-pocket costs of accessing these products; however, home delivery may be expensive, especially in rural areas.  This paper provides evid...

Willingness-to-Pay for LNS Products: Evidence from the iLiNS Studies

Stephen Vosti, Katherine Adams, Emmanuel Ayifah, Rosemonde Guissou, Thokozani Phiri, Per Ashorn, Anna Lartey, Ken Maleta, Jean Bosco Ouedraogo, Kathryn Dewey & Travis Lybbert · European Journal of Nutrition & Food Safety · 2015

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. ...

LNS Production Costs: Effects of Production Location and of Variations in Ingredient Prices and Taxes

Nicolas Lucas, Cecile Vasseur, Stephen Vosti & Mamane Zeilani · European Journal of Nutrition & Food Safety · 2015

Objectives: When scaling up maternal and child nutrition interventions using LNS, policy makers must choose production locations. This paper examines site-specific LNS production costs and factors that influence them. Methods: A production cost model is developed based on Nutrise...

Adherence to Intake Recommendations of Lipid-based Nutrient Supplements (LNS) and Iron/Folic Acid (IFA) among Pregnant and Lactating Women (PLW) in a Community Health Program Setting

Kassandra Harding, Christine Stewart, Susana Matias, Malay Mridha, Stephen Vosti & Kathryn Dewey · European Journal of Nutrition & Food Safety · 2015

Objectives: Limited knowledge exists on sustained adherence to small quantity LNS for PLW and how this compares to other prenatal supplements, particularly in programmatic settings. We aimed to address these gaps. Methods: A random subsample of women (n=360) from an ongoing LNS e...
