[en] determine the effectiveness of breastfeeding education provided by nurses. Methods: A systematic review was carried out on the object of study. A search of systematic reviews, original articles and clinical trials was carried out in the Medline, Scopus and WebofScience databases. Prior to the selection, inclusion criteria were established that had to be met: publications between 2012 - 2022 and whose language was Spanish, English or Portuguese. After selection, 548 were collected, of which, after reading by title, abstract and full text, 8 final articles were included. Results: different educational methods have been established that have been used by health professionals to achieve an increase in BF. Among them, we find virtual education through telephone sessions, which, although its benefits are many, a clear influence on ad-herence to BF cannot be determined. Scientific evidence shows better results with face-to-face education, especially those interventions that ensure follow-up of the mother and her NB, through active observation and error correction. Conclusions: it has been observed that cultural factors (return to work, family pressure, return to daily activities, hearing negative experiences about BF) negatively interfere with adherence to BF. Likewise, no definitive conclusion is reached regarding the effectiveness of virtual education compared to face-to-face education due to the lack of scientific evidence. Finally, the education provided by nurses is not considered effective since a successful EBF is not achieved according to the WHO recommendations.

[gl] determinar a eficacia da educación para a lactación materna impartida polas enfermeiras. Metodoloxía: realizouse unha revisión sistemática do obxecto de estudo. Realizouse unha busca de revisións sistemáticas, artigos orixinais e ensaios clínicos nas bases de datos Medline, Scopus e WebofScience. Previamente á selección establecéronse os criterios de inclusión que debían cumprir: publicacións entre 2012 - 2022 e cuxa lingua fose castelán, inglés ou portugués. Despois da selección, recolléronse 548, dos cales, tras a lectura por título, resumo e texto completo, incluíronse 8 artigos finais. Resultados: Establecéronse diferentes métodos educativos que foron empregados polos profesionais sanitarios para alcanzar un aumento da LM. Entre eles, atopamos a educación virtual mediante sesións telefónicas, que, aínda que os seus beneficios son moitos, non se pode determinar unha influencia clara na adherencia da LM. A evidencia científica mostra uns mellores resultados coa educación presencial, sobre todo aquelas intervencións que aseguran o seguimento da nai e a súa RN, mediante a observación activa e corrección de erros. Conclusions: observouse que os factores culturais (regreso ao traballo, presión familiar, retorno ás actividades diarias, escoitar experiencias negativas sobre a BF) interfiren negativamente coa adhesión á BF. Así mesmo, non se chega a unha conclusión definitiva sobre a efectividade da educación virtual fronte á educación presencial por falta de evidencia científica. Finalmente, a educación proporcionada polas enfermeiras non se considera eficaz xa que non se consegue un EBF exitoso segundo as recomendacións da OMS.
