Orange-fleshed sweetpotato (OFSP) is a rich plant-based source of beta-carotene, which the body converts into vitamin A. In sub-Saharan Africa, sweetpotato is known as a food security crop but most varieties grown are high dry matter white-fleshed types, lacking beta-carotene. In 1995, researcher...

Everything you ever wanted to know about sweetpotato: Reaching agents of change ToT manual. 2: Orange-fleshed sweetpotato and nutrition.
The introduction of orange sweet potato (OSP), rich in vitamin A, can have important and lasting impacts on reducing vitamin A deficiency among smallholder farmers in the developing world. In this paper, we describe the evolution of evidence about the effectiveness of disseminating OSP to smallho...

Mothers’ vitamin A (VA) status during pregnancy and lactation determine infants’ VA levels. We estimated VA status during pregnancy and assessed its determinants using data on 505 pregnant women attending first antenatal care visit in Western Kenya. VA and iron status were assessed using plasma r...

The 2013 Lancet Maternal and Child Nutrition series identified evaluations of nutrition-sensitive agricultural interventions as a research priority. The Mama SASHA study in Western Kenya links delivery of vitamin A (VA) rich orange-flesh sweet potato (OFSP) to antenatal care to improve VA and nut...

Evaluating the effectiveness of a nutrition-sensitive agriculture intervention in Western Kenya: design of the Mama SASHA cohort study of vitamin A.
In sub-Saharan Africa, more than 40% of children under five years of age suffer from vitamin A deficiency. Among several interventions in place to address vitamin A deficiency is biofortification, breeding vitamin A into key staple crops. Staple crops biofortified with beta-carotene, the precurso...

Maternal anemia is associated with poor birth outcomes. We estimated anemia and iron status and assessed its determinants using data from 505 pregnant women attending their first antenatal care visit in Western Kenya. Iron status was assessed using ferritin and transferrin receptor and corrected ...
