Capacidad predictiva para la lactancia y determinación del mejor punto de corte de la escala BSES-SF / Predictive capacity for breastfeeding and determination of the best cut-off point for the breastfeeding self-efficacy scale-short form

Introducción: El instrumento utilizado habitualmente para valorar la autoeficacia de la lactancia materna (LM) es la breastfeeding self-efficacy scale-short form (BSES-SF). Este estudio valora la relación entre la puntuación de la BSES-SF y el riesgo de abandono de la lactancia. También se determina el punto de corte en la puntuación de la escala que optimiza la detección de este riesgo desde la atención primaria. Métodos: Análisis secundario de datos del estudio Lactancia y Desarrollo Infantil (LAyDI). Ensayo de cohorte única realizado a través de la red de investigación de pediatras de atención primaria (PAPenRed). Cada especialista reclutó un recién nacido cada mes durante un año. Se siguió la cohorte durante 24 meses. Las madres respondieron la BSES-SF en la primera visita. Se recogieron datos generales de el embarazo y el parto y se valoró la LM (suplementada o exclusiva) hasta los seis meses. Resultados: n = 1.845. El área bajo la curva ROC para la LM exclusiva fue al primer mes de 0,79 (0,77 a 0,82) y al segundo mes de 0,760 (0,734 a 0,786). Para los cuatro y seis meses, así como para cualquier edad en las madres que dan LM suplementada, el área bajo la curva fue menor de 0,75 y su capacidad predictiva no se consideró adecuada. Para una sensibilidad del 80% en la detección de las mujeres en riesgo de abandono de la lactancia, la puntuación de corte fue 58. Conclusiones: Las madres que en atención primaria presenten una puntuación en la BSES-SF por debajo de 58 tienen riesgo de abandono de la LM exclusiva antes de los dos meses.(AU)

Introduction: The most widely used tool for assessing breastfeeding self-efficacy is the Breastfeeding Self-Efficacy Scale-Short Form (BSES-SF). This study asses the relationship between the BSES-SF score and the risk of breastfeeding (BF) cessation and determine the cut-off point in the scale score that optimizes detection of this risk in primary health care pediatric consultations. Methods: Secondary data analysis of the LAyDI study. It is a cohort study. It was carried out through a research network of primary care pediatricians (PAPenRed). A newborn was recruited every month for one year by 210 pediatricians. The cohort was followed for 24 months. Mothers responded to the BSES-SF at the first visit. General pregnancy and delivery data were collected and assessed to determine whether breastfeeding was exclusive or supplemented during the first six months. Results: n = 1,845. The area under the ROC curve for the exclusive BF was 0.790 (0.765-0.815) the first month and 0.760 (0.734-0.786) the second month. For four and six months, as well as for any age in mothers who give supplemented BF, the Area Under the Curve was less than 0.75 and its predictive capacity was not considered to be good. For a sensitivity of 80% in detecting mothers at risk of BF cessation with the BSES-SF, the cut-off score was 58. Conclusions: Mothers with a BSES-SF score below 58 points in primary health care, are at risk of early withdrawal of exclusive BF within two months.(AU)

General pregnancy and delivery data were collected and assessed to determine whether breastfeeding was exclusive or supplemented during the first 6 months. RESULTS: N = 1845. The Area Under the ROC Curve for the exclusive BF was 0.790 (0.765-0.815) the first month and 0.760 (0.734-0.786) the second month. For 4 and 6 months, as well as for any age in mothers who give supplemented BF, the Area Under the Curve was less than 0.75 and its predictive capacity was not considered to be good. For a sensitivity of 80% in detecting mothers at risk of BF cessation with the BSES-SF, the cut-off score was 58.
