The experiment involved 431 preschooler\u2013caregiver pairs in 15 villages. The preschoolers were enrolled in public\u2010run Early Childhood Development and Education (ECDE) centers in the respective villages. Caregivers were first exposed to the routine OFSP promotion activities in the area \u2013 invited to cooking demonstration workshops and issued with free OFSP vines to plant. A baseline survey followed. Next, the 15 villages were randomized into four study groups (a control and three treatments). The interventions were deployed for 30\u2009days as follows: Treatment 1 \u2013 preschoolers issued OFSP\u2010branded exercise books, class posters, and poems; Treatment 2 \u2013 caregivers received phone\u2010mediated text messages; and Treatment 3 \u2013 received the full suite of interventions. This study analyzed the endline and baseline data and finds that, in general, changes in KAP scores were negatively associated with control group (<jats:italic>p<\/jats:italic>\u00a0=\u00a0.005) and positively associated with Treatment 3 (<jats:italic>p<\/jats:italic>\u00a0=\u00a0.02). Specifically, Treatment 3 significantly increased caregivers' knowledge of OFSP production, consumption, and vitamin A. Treatment 2 significantly improved their attitude too. It concludes that an integrated complementary nutrition education approach targeting preschooler\u2013caregiver pairs is more effective in increasing knowledge of cultivation and consumption of OFSP. It discusses the implications for the design of more effective nutrition programs targeting households with preschoolers to accelerate the fight against vitamin A deficiency (VAD).<\/jats:p>","DOI":"10.1002\/fsn3.2960","type":"journal-article","created":{"date-parts":[[2022,7,22]],"date-time":"2022-07-22T14:45:25Z","timestamp":1658501125000},"page":"3627-3637","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Using preschoolers to improve caregivers' knowledge, attitude, and practices relating to biofortified crops: Evidence from a randomized nutrition education trial in Kenya"],"prefix":"10.1002","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3171-0895","authenticated-orcid":false,"given":"Sylvester Okoth","family":"Ojwang\u2019","sequence":"first","affiliation":[{"name":"Department of Agricultural Economics University of Nairobi  Nairobi Kenya"},{"name":"International Potato Centre  Nairobi Kenya"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2217-2770","authenticated-orcid":false,"given":"Julius Juma","family":"Okello","sequence":"additional","affiliation":[{"name":"International Potato Centre  Kampala Uganda"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9904-0819","authenticated-orcid":false,"given":"David Jakinda","family":"Otieno","sequence":"additional","affiliation":[{"name":"Department of Agricultural Economics University of Nairobi  Nairobi Kenya"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6117-7705","authenticated-orcid":false,"given":"Rose Adhiambo","family":"Nyikal","sequence":"additional","affiliation":[{"name":"Department of Agricultural Economics University of Nairobi  Nairobi Kenya"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8352-2183","authenticated-orcid":false,"given":"Penina Ngusye","family":"Muoki","sequence":"additional","affiliation":[{"name":"International Potato Centre  Nairobi Kenya"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2022,7,22]]},"reference":[{"key":"e_1_2_10_2_1","volume-title":"Knowledge, attitudes, beliefs and behavior of mothers of young children related to healthy eating: Comparing rural and urban perspectives in Nepal","author":"Acharya J.","year":"2018"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1093\/acprof:oso\/9780198733201.003.0004"},{"key":"e_1_2_10_4_1","volume-title":"A closer look at hunger and nutrition in Kenya","author":"Bernstein J.","year":"2018"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.3368\/jhr.50.2.317"},{"key":"e_1_2_10_6_1","volume-title":"Second county integrated development plan (CIDP) 2018\u20132022","author":"County Government of Homa Bay","year":"2018"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1177\/0272989X18785159"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1177\/1536867X1501500117"},{"key":"e_1_2_10_9_1","volume-title":"Handbook of development economics","author":"Duflo E.","year":"2008"},{"key":"e_1_2_10_10_1","volume-title":"Why nutrition education matters: Nutrition education and consumer awareness group","author":"FAO","year":"2011"},{"key":"e_1_2_10_11_1","volume-title":"The state of food security and nutrition in the world 2020.
