β-Carotene-rich orange sweet potato (OSP) has been shown to improve vitamin A status of infants and young children in controlled efficacy trials and in a small-scale effectiveness study with intensive exposure to project inputs. 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 6-35 months and 3-5·5 years of age, and women. The intervention resulted in significant net increases in OSP intakes (model 1: 46, 48 and 97 g\/d) and vitamin A intakes (model 1: 263, 254 and 492 μg retinol activity equivalents\/d) among the younger children, older children and women, respectively. OSP accounted for 47-60 % of all sweet potato consumed and, among reference children, provided 80 % 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.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-37232","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"HarvestPlus, International Food Policy Research Institute, 2033 K Street NW, Washington DC 20006, USA","annee":"2012","mois":"7","numero":"108:1","page":"163-176","auteurs":[{"ID":37229,"post_author":"0","post_date":"2018-12-04 01:13:31","post_date_gmt":"2018-12-04 00:13:31","post_content":"","post_title":"Hotz","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"hotz","to_ping":"","pinged":"","post_modified":"2018-12-04 01:13:31","post_modified_gmt":"2018-12-04 00:13:31","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/hotz\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":37230,"post_author":"0","post_date":"2018-12-04 01:13:32","post_date_gmt":"2018-12-04 00:13:32","post_content":"","post_title":"Loechl","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"loechl","to_ping":"","pinged":"","post_modified":"2018-12-04 01:13:32","post_modified_gmt":"2018-12-04 00:13:32","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/loechl\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":37231,"post_author":"0","post_date":"2018-12-04 01:13:32","post_date_gmt":"2018-12-04 00:13:32","post_content":"","post_title":"De Brauw","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"de-brauw","to_ping":"","pinged":"","post_modified":"2018-12-04 01:13:32","post_modified_gmt":"2018-12-04 00:13:32","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/de-brauw\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":1559,"post_author":"0","post_date":"2018-12-03 16:00:30","post_date_gmt":"2018-12-03 15:00:30","post_content":"","post_title":"Br J Nutr.","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"br-j-nutr","to_ping":"","pinged":"","post_modified":"2018-12-03 16:00:30","post_modified_gmt":"2018-12-03 15:00:30","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/br-j-nutr\/","menu_order":0,"post_type":"source","post_mime_type":"","comment_count":"0","filter":"raw"}]},"yoast_head":"\nA large-scale intervention to introduce orange sweet potato in rural mozambique increases vitamin A intakes among children and women -
