This study was conducted to assess the impact of the behaviour change communication (BCC) campaign of the project on volume of sales of vitamin A\u2010fortified sunflower oil. The e\u2010Voucher system provides real\u2010time data on the number of e\u2010Vouchers redeemed. The number, type, and locations of BCC events were obtained from the implementation agency. Multivariate linear regression was used to examine the associations between (a) the number and type of BCC events conducted in a ward and the volume of subsequent fortified oil redeemed in the ward and (b) distance of clinic shows, a component of the BCC campaign, from participating retailers and the volume of fortified oil redeemed in the store. After 1\u00a0year of the campaign, the volume of fortified oil redeemed monthly increased by more than 5 times in Manyara and by more than three times in Shinyanga. Among the different types of BCC events conducted, only clinic shows and cooking shows were significantly associated with the volume of redemptions (<jats:italic>p<\/jats:italic>\u00a0&lt;\u00a0.05). Compared with retailers where at least one clinic show was conducted within 0.5\u00a0km from its location, the volume of redemptions was significantly lower at retailers where no clinic show conducted within 3.0\u00a0km from its location (<jats:italic>p<\/jats:italic>\u00a0&lt;\u00a0.05). These findings suggest that future health promotion interventions in rural Africa should involve health clinics.<\/jats:p>","DOI":"10.1111\/mcn.12873","type":"journal-article","created":{"date-parts":[[2019,7,9]],"date-time":"2019-07-09T00:12:57Z","timestamp":1562631177000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Impact of behaviour change communication interventions on sales of fortified sunflower oil in Tanzania: A spatial\u2013temporal analysis and association study"],"prefix":"10.1111","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6700-9996","authenticated-orcid":false,"given":"Daphne Chen Nee","family":"Wu","sequence":"first","affiliation":[{"name":"School of Public Health and Health Systems University of Waterloo  Waterloo ON Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sue","family":"Horton","sequence":"additional","affiliation":[{"name":"School of Public Health and Health Systems University of Waterloo  Waterloo ON Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nadira","family":"Saleh","sequence":"additional","affiliation":[{"name":"Mennonite Economic Development Associates of Canada  Waterloo ON Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Theobald C.E.","family":"Mosha","sequence":"additional","affiliation":[{"name":"Department of Food Technology, Nutrition and Consumer Sciences Sokoine University of Agriculture  Morogoro Tanzania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nazir","family":"Yusuph","sequence":"additional","affiliation":[{"name":"Tanzania Communication and Development Center  Dar es Salaam Tanzania"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2019,8,2]]},"reference":[{"volume-title":"Guidelines on food fortification with micronutrients","year":"2006","author":"Allen L.","key":"e_1_2_9_2_1"},{"unstructured":"Brinkhoff T.
