However, evidence regarding their impact on behavioral and anthropometric outcomes remains heterogeneous, particularly in Latin American settings. Objective: The aim of this study was to evaluate the influence of a parent-oriented nutrition education program on parental nutrition knowledge, dietary habits, and the nutritional status of schoolchildren with excess weight. Methods: A randomized controlled experimental study was conducted in a public educational institution in Peru. From a total population of 411 schoolchildren, a population-based screening was performed to identify those with excess weight; of the 198 children assessed, 64 met the inclusion criteria and were randomly assigned (1:1) to an intervention group or a control group. The educational program consisted of theoretical sessions, practical workshops, and home-based reinforcement over a three-month period. Outcomes included parental nutrition knowledge, children\u2019s dietary habits, and body mass index-for-age Z-score according to sex. Longitudinal analyses were performed using linear mixed-effects regression models. Results: The intervention group showed a significant increase in parental nutrition knowledge compared with the control group (\u03b2 = 5.65; 95% CI: 2.25\u20139.06; p = 0.002). No significant effects of the program were observed on dietary habits or BMI-for-age Z-score (p &gt; 0.05). Conclusions: The nutrition education program significantly improved parental nutrition knowledge but did not lead to short-term changes in dietary habits or nutritional status among schoolchildren. These findings highlight the need for longer-term and multicomponent interventions to achieve meaningful behavioral and anthropometric changes.<\/jats:p>","DOI":"10.3390\/nu18040613","type":"journal-article","created":{"date-parts":[[2026,2,13]],"date-time":"2026-02-13T10:52:21Z","timestamp":1770979941000},"page":"613","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Influence of a Nutrition Education Program on Parental Nutrition Knowledge, Dietary Habits, and Nutritional Status in Schoolchildren with Excess Weight"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5228-4370","authenticated-orcid":false,"given":"Alexander Javier","family":"Iman Torres","sequence":"first","affiliation":[{"name":"Departamento de Ciencia y Tecnolog\u00eda de Alimentos, Facultad de Industrias Alimentarias, Universidad Nacional de la Amazon\u00eda Peruana, Iquitos 16001, Peru"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-4938-0932","authenticated-orcid":false,"given":"El\u00ed Guillermo","family":"L\u00f3pez Padilla","sequence":"additional","affiliation":[{"name":"Departamento de Ciencia y Tecnolog\u00eda de Alimentos, Facultad de Industrias Alimentarias, Universidad Nacional de la Amazon\u00eda Peruana, Iquitos 16001, Peru"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-0932-3398","authenticated-orcid":false,"given":"Lesly Janela","family":"Baneo Shapiama","sequence":"additional","affiliation":[{"name":"Departamento de Ciencia y Tecnolog\u00eda de Alimentos, Facultad de Industrias Alimentarias, Universidad Nacional de la Amazon\u00eda Peruana, Iquitos 16001, Peru"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8246-5172","authenticated-orcid":false,"given":"Carlos Antonio","family":"Li Loo Kung","sequence":"additional","affiliation":[{"name":"Departamento de Ingener\u00eda de Alimentos, Facultad de Industrias Alimentarias, Universidad Nacional de la Amazon\u00eda Peruana, Iquitos 16001, Peru"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5235-532X","authenticated-orcid":false,"given":"Susy Karina","family":"D\u00e1vila Panduro","sequence":"additional","affiliation":[{"name":"Departamento de Ciencias Sociales, Facultad de Ciencias de la Educaci\u00f3n y Humanidades, Universidad Nacional de la Amazon\u00eda Peruana, Iquitos 16000, Peru"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4949-9159","authenticated-orcid":false,"given":"Jessy Patricia","family":"V\u00e1squez Chumbe","sequence":"additional","affiliation":[{"name":"Departamento de Ciencia y Tecnolog\u00eda de Alimentos, Facultad de Industrias Alimentarias, Universidad Nacional de la Amazon\u00eda Peruana, Iquitos 16001, Peru"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7239-960X","authenticated-orcid":false,"given":"Antonio","family":"Castillo-Paredes","sequence":"additional","affiliation":[{"name":"Grupo AFySE, Investigaci\u00f3n en Actividad F\u00edsica y Salud Escolar, Escuela de Pedagog\u00eda en Educaci\u00f3n F\u00edsica, Facultad de Educaci\u00f3n, Universidad de Las Am\u00e9ricas, Santiago 8370040, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0774-606X","authenticated-orcid":false,"given":"Jose Jairo","family":"Narrea Vargas","sequence":"additional","affiliation":[{"name":"Grupo de Investigaci\u00f3n en Nutrici\u00f3n, Metabolismo y Ejercicio, Facultad de Ciencias de la Salud, Carrera de Nutrici\u00f3n y Diet\u00e9tica, Universidad Cient\u00edfica del Sur, Lima 15067, Peru"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,2,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Shamah-Levy, T., Del Monte-Vega, M.Y., Valenzuela-Bravo, D.G., Morales-Ruan, C., Moreno-Mac\u00edas, L., Galindo-G\u00f3mez, C., Fajardo-Niquete, I., and Troconis-Cervera, J.
