[en] Introduction: In Spain approximately 15% of schoolchildren have a chronic health problem. In addition, in recent years there has been an increase in obesity, allergies and sedentary life. Taking into account the Spanish education law of 1990 (LOGSE), the presence of these children is increasingly frequent in schools. Both parents and teachers are incapable of solving these health problems on their own. In view of this, the need arises for a health professional who is integrated into the school, who carries out health interventions and who works in them on a daily basis: The school nurse. Objective: The objective of our study is to know the evidence of the interventions of the school nurse as a health promoter in schools. Methodology: We have carried out a systematic review in order to locate the scientific literature of the last 6 years on the subject to be studied. First, a bibliographic search was carried out in Pubmed, aimed at finding the latest available systematic reviews. Subsequently, another search was made in databases of health sciences (Pubmed, Cinahl) and multidisciplinary (Web of Science) to find original studies. The search strategy was limited to studies published from 2013 to March 2019, in English and Spanish. Results: Results related to nursing interventions and student health demonstrate improvements in diet, physical activity, asthma management, and decreased absenteeism. Conclusions: School nursing is a great support for the educational system, not only through prevention activities and direct action in the event of an accident, but also in health education, necessary to create healthy habits in children and adolescents, and thus avoid future problems by reducing health costs in the long term.

[gl] Introdución: En España aproximadamente un 15% dos escolares ten algún problema crónico de saúde. Ademais nos últimos anos produciuse un aumento da obesidade, as alerxias e o sedentarismo. Tendo en conta a lei española de educación de 1990 (LOGSE), a presenza destes nenos é cada vez máis frecuente nos colexios. Tanto os pais como os profesores, móstranse incapaces de resolver por si sós estes problemas de saúde. Ante isto xorde a necesidade dun profesional sanitario que estea integrado no colexio, que execute intervencións de saúde e que traballe diariamente neles: A enfermeira escolar. Obxectivo: O obxectivo do noso estudo é coñecer a evidencia das intervencións da enfermeira escolar como promotora de saúde nos colexios. Metodoloxía: Realizamos unha revisión sistemática co fin de localizar a literatura científica dos últimos 6 anos sobre o tema para estudar. En primeiro lugar, levou a cabo unha procura bibliográfica en Pubmed, destinada a atopar as últimas revisións sistemáticas dispoñibles. Posteriormente, efectuouse outra procura en bases de datos de ciencias da saúde ( Pubmed, Cinahl) e multidisciplinares (Web of Science) para achar estudos orixinais. A estratexia de procura limitouse a estudos publicados desde o ano 2013 ata marzo de 2019, en inglés e español. Resultados: Os resultados relacionados coas intervencións de enfermería e a saúde dos estudantes demostran melloras na alimentación, na actividade física, no manexo da asma e tamén demostran unha diminución do ausentismo escolar. Conclusións: A enfermería escolar supón un gran apoio para o sistema educativo, non só a través de actividades de prevención e actuacións directas en caso de accidente, senón tamén na educación para a saúde, necesaria para crear hábitos saudables en nenos e adolescentes, e así evitar problemas futuros reducindo custos sanitarios a longo prazo.
