However, the potential of this important food crop to reduce the risk of vitamin A deficiency in deficient populations will depend on the ability to distribute OSP vines and promote its household production and consumption on a large scale. In rural Mozambique, we conducted a randomised, controlled effectiveness study of a large-scale intervention to promote household-level OSP production and consumption using integrated agricultural, demand creation\/behaviour change and marketing components. The following two intervention models were compared: a low-intensity (1 year) and a high-intensity (nearly 3 years) training model. The primary nutrition outcomes were OSP and vitamin A intakes by children 6\u201335 months and 3\u20135\u00b75 years of age, and women. The intervention resulted in significant net increases in OSP intakes (model 1: 46, 48 and 97\u00a0g\/d) and vitamin A intakes (model 1: 263, 254 and 492\u00a0\u03bcg retinol activity equivalents\/d) among the younger children, older children and women, respectively. OSP accounted for 47\u201360\u00a0% of all sweet potato consumed and, among reference children, provided 80\u00a0% of total vitamin A intakes. A similar magnitude of impact was observed for both models, suggesting that group-level trainings in nutrition and agriculture could be limited to the first project year without compromising impact. Introduction of OSP to rural, sweet potato-producing communities in Mozambique is an effective way to improve vitamin A intakes.<\/jats:p>","DOI":"10.1017\/s0007114511005174","type":"journal-article","created":{"date-parts":[[2011,10,10]],"date-time":"2011-10-10T16:01:45Z","timestamp":1318262505000},"page":"163-176","source":"Crossref","is-referenced-by-count":209,"title":["A large-scale intervention to introduce orange sweet potato in rural Mozambique increases vitamin A intakes among children and women"],"prefix":"10.1017","volume":"108","author":[{"given":"Christine","family":"Hotz","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cornelia","family":"Loechl","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alan","family":"de Brauw","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Patrick","family":"Eozenou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel","family":"Gilligan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mourad","family":"Moursi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bernardino","family":"Munhaua","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul","family":"van Jaarsveld","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alicia","family":"Carriquiry","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.
