A non-randomised community intervention trial. Three socio-demographically similar primary schools of a deprived neighborhood in Granada, Spain. Eighty-two intervention and 109 control students aged 5 to 6, as well as the teachers and the parent's association of the intervention school (IS) participated in the study. School-based health promotion activities aimed at students, and regular meetings with the teachers and parents of the IS during 2 consecutive years. Students' oral health-related knowledge and behavior, assessed via questionnaires distributed before the intervention, and 6 and 18 months afterwards. Compared to the control groups at 18 months, students belonging to the IS reported enhanced oral health knowledge (OR 3.54; 95% CI 1.46-8.58), and an increased consumption of healthy food at breakfast (OR 2.95; 95% CI 1.26-6.89) and during mid-afternoon snack (OR 3.67; 95% CI 1.49-9.05). A significant decrease was seen in the intake of pastries (OR 4.05; 95% CI 1.68-9.81) and sweetened soft drinks and juices (OR 3.79; 95% CI 1.57-9.12) amongst intervention compared to control students in the medium term (18 months). No significant improvements were observed concerning oral hygiene in the IS. School-based educational interventions, when developed through an intersectoral and participative approach and considering the socio-economic context, appear to be effective in improving students' diet-related knowledge and behaviors.esAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Atención PrimariaHealth promotionOral healthPrimary Health CarePromoción de la saludSalud bucalSchool health servicesServicios de salud escolarChildChild, PreschoolDiet, HealthyHealth PromotionHumansOral HealthOral HygienePoverty AreasPrimary Health CareProgram EvaluationSchool Health ServicesSpainresearch article30316564open access10.1016/j.aprim.2018.05.0031578-1275PMC6839536https://doi.org/10.1016/j.aprim.2018.05.003https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6839536/pdf
