Infant and young child feeding practices (IYCF) are crucial predictors of the nutritional status of children. This study evaluated the effects of utilization of the BabyThrive app versus control on IYCF knowledge of Nigerian teenage mothers. Methods: A parallel, randomized controlled trial was conducted with 194 low-income teenage mother\u2013child (0\u20132 years) dyads in Nigeria. Outcome measures included knowledge concerning food type for an infant, exclusive breastfeeding, complementary feeding, and total IYCF knowledge scores. Results: No significant differences in demographic characteristics or IYCF knowledge were found at baseline. Post-intervention, almost all BabyThrive participants vs. only 36.1% of controls were aware that expressed breast milk is the ideal food for an infant &lt;6 months, when a mother resumes work (p &lt; 0.05). As compared to the BabyThrive group, knowledge of how to maintain breast milk supply (5.2% vs. 83.5%), the duration of safety of breast milk at room temperature (15.4% vs. 85.6%), responsive feeding (58.8% vs. 96.9) and dietary diversity (15.5% vs. 99%) was substantially lower in controls (p &lt; 0.05). Mean knowledge on exclusive breastfeeding (25.17 \u00b1 1.37 vs. 19.87 \u00b1 1.80), complementary feeding (15.68 \u00b1 0.60, vs. 13.51 \u00b1 1.21) and total knowledge scores (46.8 \u00b1 1.79 vs. 38.65 \u00b1 2.71) was higher in the BabyThrive group (p &lt; 0.05). Conclusions: In sum, the BabyThrive app significantly increased maternal IYCF knowledge in comparison with controls. It will be a useful tool to improve maternal IYCF knowledge in resource-limited areas.<\/jats:p>","DOI":"10.3390\/nu17030414","type":"journal-article","created":{"date-parts":[[2025,1,23]],"date-time":"2025-01-23T12:24:09Z","timestamp":1737635049000},"page":"414","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["A Mobile-Based Approach to Enhance Knowledge of Infant and Young Child Feeding Among Teenage Mothers in Nigeria: A Randomized Controlled Trial"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9802-0269","authenticated-orcid":false,"given":"Mercy E.","family":"Sosanya","sequence":"first","affiliation":[{"name":"Department of Nutritional Sciences, University of Texas at Austin, Austin, TX 78712, USA"},{"name":"Department of Nutrition and Dietetics, The Federal Polytechnic, Bauchi, Bauchi 740102, Nigeria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Oluwatosin D.","family":"Adesanya","sequence":"additional","affiliation":[{"name":"Department of Nutrition and Dietetics, The Federal Polytechnic, Bauchi, Bauchi 740102, Nigeria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hauwa E.","family":"Rufai","sequence":"additional","affiliation":[{"name":"Department of Nutrition and Dietetics, The Federal Polytechnic, Bauchi, Bauchi 740102, Nigeria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeanne H.","family":"Freeland-Graves","sequence":"additional","affiliation":[{"name":"Department of Nutritional Sciences, University of Texas at Austin, Austin, TX 78712, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,1,23]]},"reference":[{"key":"ref_1","unstructured":"Government of the Federal Republic of Nigeria, United Nations Children\u2019s Fund (2023).
