Resumen

Objetivo: evaluar los factores asociados al uso temprano e inadecuado de fórmula infantil durante la hospitalización en la Unidad de Alojamiento Conjunto. Método: estudio transversal realizado con primíparas asistidas en hospitales universitarios de Minas Gerais y Río de Janeiro entre diciembre de 2023 y abril de 2024. Se aplicaron pruebas de chi-cuadrado y exacta de Fisher. Se calcularon razones de prevalencia y regresión de Poisson con varianza robusta. Resultados: se incluyeron 102 díadas; el 42,2% de los neonatos recibieron fórmula; el 22,5% la recibió antes del inicio de la lactancia materna. El análisis bivariado mostró asociación con maternidad Amiga del Niño (p<0,001), orientación prenatal (p=0,007), contacto piel con piel (p=0,006) y lactancia materna en la primera hora (p=0,003) como factores protectores para la lactancia materna. La cesárea (p=0,016) se identificó como factor de riesgo. Ninguna variable explicó el uso de fórmula mediante regresión. Conclusión: dos de cada cinco recién nacidos recibieron fórmula. Sin embargo, no se encontraron factores que justificaran su uso temprano e inadecuado.
