Objetivo: Analizar y determinar mediante una revisión sistemática el impacto que tiene el método BLW sobre la salud nutricional en bebés de 6 a 12 meses. Método: La metodología que se desarrollará está basado en el artículo de Tricco A, et al del a2018 y el de Peters MD,et al del año 2015. En el artículo de Peters, et al, mencionan que en una revisión sistemática exploratoria se debe realizar una búsqueda rigurosa y extensa de la literatura internacional. Así como definir los objetivos, los métodos y detallar los planes propuestos. Los artículos primarios investigados deben ser clasificados por el tipo de intervención, población, duración de la intervención, palabras clave. Asimismo, mencionan que las revisiones sistemáticas exploratorias son útiles para reunir evidencia, ya que, son adecuadas para abordar preguntas más allá de la efectividad o la experiencia en una intervención.

Introduction: The BLW method (Baby-Led Weaning) is an increasingly used method of introducing complementary nutrition to infants, in which the phase of feeding a puree with a spoon is completely omitted and larger pieces of food are immediately offered to the infants. There are concerns that children at BLW may cause worse thriving of them. Aims: The main aim of the work is to compare the somatic parameters of 12 months old infants depending on the method of feeding. The partial goals are to find out how much information parents have about the BLW method and what their child's nutrition looks like in their first year of life. Methods: Retrospective observational research was carried out by means of a questionnaire survey among parents of toddlers aged from the end of the 12th month to the end of the 18th month. The set consisted of 186 respondents for the evaluation of general information about the child's nutrition. Somatic parameters (head circumference, length/height, weight and weight/length [height] ratio at 12 months) were evaluated in a set of 153 respondents, the data were obtained from the child's health card. Data collection took place at the turn of February and March 2021. The data comparison was performed by t-test and ANOVA test. Results: The mean weight percentile at 12 months is...
