Esta investigación plantea una intervención en educación física, basada en estrategias docentes propias de la Teoría de la Autodeterminación y la Teoría de Metas de Logro, con el objetivo de potenciar la práctica de actividad física y el desarrollo de las inteligencias múltiples en estudiantes de 5º y 6º de Educación Primaria. La muestra del estudio está formada por 230 estudiantes, 88 participantes del grupo control y 142 participantes del grupo experimental. Se han empleado los cuestionarios Enkid y FITNESSGRAM para medir la actividad física, el cuestionario de apoyo a las necesidades psicológicas básicas, el cuestionario de motivación en educación física y el cuestionario de inteligencias múltiples. Los resultados muestran que la práctica de actividad física se relaciona positivamente con las necesidades psicológicas básicas, con la motivación intrínseca e identificada y con algunas inteligencias como la lingüística, matemática, corporal e interpersonal. Finalmente, una vez terminada la intervención, el alumnado del grupo experimental presenta mayores niveles en la práctica de AF, en la necesidad de autonomía, en la motivación intrínseca, así como en las inteligencias corporal-kinestésica y musical en comparación con los estudiantes del grupo control.

Background/Objectives: Micronutrient malnutrition, particularly deficiencies in calcium, vitamin D, iron, zinc, and iodine, remains a significant public health issue among school-aged children in Morocco. Processed cheese, such as “The Laughing Cow” (TLC), has potential as a vehicle for fortification due to its widespread consumption and accessibility. This study aimed to evaluate the impact of fortified TLC on micronutrient intake and adequacy relative to the Recommended Dietary Allowances (RDA), among Moroccan children aged 6–12 years, and to explore differences in effects by socioeconomic status (SES). Methods: Data from the Moroccan Household Budget Survey (2013–2014) included 9266 children (39.4% TLC consumers). Dietary intake was assessed using 24 h recalls, and nutrient composition was analyzed using Ciqual 2020 tables and specialized software. Fortification scenarios were modelled to estimate potential impacts on micronutrient intake and compliance with RDAs. Results: Under the modelling scenarios, consumption of one portion/day of fortified TLC significantly improved RDAs compliance for iron, iodine, and zinc (p < 0.05). There was also an increase in RDA compliance for calcium and vitamin D, but differences were not significant. The impact of fortification on micronutrient intake and RDA compliance increased with socioeconomic status. Consumers of more than one portion/day showed the highest compliance with RDAs (p < 0.001). Fortification effects were consistent across age subgroups. Conclusions: Fortifying processed cheese represents a feasible strategy to address micronutrient deficiencies among Moroccan schoolchildren. This study highlights the potential of targeted fortification programmes to improve public health outcomes, particularly in vulnerable populations. Further research is needed to optimize fortification approaches and ensure sustainability.
