The Reaching End Users project introduced orange sweet potatoes to farmers in northern Mozambique between 2006 and 2009, and the associated cluster randomized control trial found increased vitamin A intakes among targeted children and women of child-bearing age and reduced prevalence of vitamin A intake inadequacy. Yet little is known about whether successful agricultural-nutrition interventions have lasting effects. This study measures the lasting effects of the Reaching End Users project, three years after the project ended, on vitamin A intakes. To do so, dietary intake data were collected in the same 36 villages as the original study, focusing on both women of child-bearing age and children under 6 years old, the latter including both children who had been measured before as well as younger children (under 3 years old) in the same farmer groups. The dietary intakes are then converted to micronutrient intakes to compare treated households with control households. Vitamin A intakes remain higher in treated villages than in control villages among both children under 3 years old, who had not been born when the original intervention ended, and among mothers of child-bearing age. Differences in vitamin A intakes can wholly be attributed to differences in orange sweet potato intakes. Therefore the Reaching End Users project appears to have had lasting impacts on vitamin A intakes beyond the intervention period. Had the vine retention component been enhanced, lasting impacts could have been even larger.
