Abstract
in English, Portuguese, Spanish

Objectives: to compare exclusive breastfeeding prevalence versus artificial feeding in newborns of mothers with COVID-19.

Methods: a systematic review of prevalence, according to JBI. Searches in PubMed®, Embase, CINAHL, LILACS and Web of Science™ databases in August 2021. Cross-sectional, longitudinal or cohort studies were selected, without language and time limitations that showed breastfeeding prevalence or that allowed calculation.

Results: fifteen articles published in 2020 and 2021, cohort (60%) or cross-sectional (40%) were analyzed. The average of exclusive breastfeeding in mothers with COVID-19 was 56.76% (CI=39.90-72.88), and artificial breastfeeding, 43.23% (CI = 30.99 - 55.88), without statistically significant differences.

Conclusions: despite the recommendations for maintaining breastfeeding, there was a reduction worldwide, when compared to periods prior to the pandemic. With advances in science, these rates have improved, showing the impact of evidence on practices. As limitations, study sources are cited. It is recommended to carry out new studies. PROSPERO registration CRD42021234486.

Objetivos:: comparar as prevalências de aleitamento materno exclusivo versus aleitamento artificial em recém-nascidos de mães com COVID-19.

Métodos:: revisão sistemática de prevalência, segundo JBI. Buscas nas bases PubMed®, Embase, CINAHL, LILACS e Web of Science™ em agosto de 2021. Selecionados estudos transversais, longitudinais ou coortes, sem limitação de idioma e tempo que apresentavam prevalência de aleitamento materno ou que permitissem o cálculo.

Resultados:: 15 artigos publicados em 2020 e 2021, coortes (60%) ou transversais (40%) foram analisados. A média de aleitamento materno exclusivo em mães com COVID-19 foi 56,76% (IC=39,90–72,88), e artificial, de 43,23% (IC = 30,99 – 55,88), sem diferenças estatisticamente significantes.

Conclusões:: apesar das recomendações para a manutenção do aleitamento materno, houve redução mundialmente, quando comparados à períodos anteriores à pandemia. Com avanços da ciência, esses índices têm melhorado, mostrando o impacto das evidências nas práticas. Como limitações, citam-se fontes dos estudos. Recomenda-se realização de novos estudos. Registro PROSPERO CRD42021234486.

Objetivos:: comparar la prevalencia de lactancia materna exclusiva versus alimentación artificial en recién nacidos de madres con COVID-19.

Métodos:: revisión sistemática de prevalencia, según JBI. Búsquedas en las bases de datos PubMed®, Embase, CINAHL, LILACS y Web of Science™ en agosto de 2021. Se seleccionaron estudios transversales, longitudinales o de cohortes, sin limitaciones de idioma y tiempo que mostraran prevalencia de lactancia materna o que permitieran calcular.

Resultados:: se analizaron 15 artículos publicados en 2020 y 2021, de cohorte (60%) o transversal (40%). El promedio de lactancia materna exclusiva en madres con COVID-19 fue 56,76% (IC=39,90-72,88), y lactancia artificial, 43,23% (IC = 30,99 – 55,88), sin diferencias estadísticamente significativas.

Conclusiones:: a pesar de las recomendaciones de mantener la lactancia materna, hubo una reducción a nivel mundial, en comparación con períodos previos a la pandemia. Con los avances de la ciencia, estas tasas han mejorado, mostrando el impacto de la evidencia en las prácticas. Como limitaciones se citan las fuentes del estudio. Se recomienda realizar nuevos estudios. Registro PROSPERO CRD42021234486.
