Lactancia materna en España y factores relacionados con su instauración y mantenimiento: estudio LAyDI (PAPenRed) / Breastfeeding in Spain and the factors related to its establishment and maintenance: LAyDI Study (PAPenRed)

Objetivo: Conocer estadísticas reales sobre lactancia materna en España, así como factores socioculturales y perinatales que afectan a su inicio y mantenimiento. Diseño: Estudio prospectivo, multicéntrico, longitudinal, de ámbito nacional (estudio LAyDI). Sitio: Consulta de pediatras de atención primaria. Participantes: Cohorte de recién nacidos entre abril de 2017 y marzo de 2018 en España que se siguieron hasta los dos años en ocho visitas. Medidas principales: Se analizaron las tasas de los diferentes tipos de lactancia en cada visita y también se analizaron variables relacionadas con la gestación, el parto, el período neonatal, sociales, económicas y biológicas. Resultados: Muestra inicial de 1.946 (50,1% varones). El 90,7% decidieron iniciar lactancia materna al nacimiento. La cifra de lactancia materna exclusiva (LME) fue del 66,4% a los 15días y del 35,2% a los 6meses. Cualquier tipo de lactancia materna (lactancia materna total [LMT]) a los 6meses fue del 61,7%. La supervivencia de LMT presentó una mediana de 6,0meses (IC95%: 6,0-6,1). Variables relacionadas con LME a los 15días: hijos previos, nivel de educación de madre, ausencia de enfermedad durante el embarazo, no separación madre e hijo al nacer, no utilización de chupete, no existencia de problemas en pezones, y momento de decisión tipo lactancia. Variables relacionadas con mayor duración LMT son: la relación mayor de 5años de los padres, no usar de chupete, colecho al mes de vida, decidir lactancia materna antes del embarazo, recibir información sobre lactancia durante el embarazo y utilizar apoyo de asociaciones. Conclusiones: El abandono temprano de la lactancia materna es un problema importante en las sociedades occidentales. Existen factores sobre los que se puede actuar para mejorar resultados.(AU)

Objective: To find out actual statistics on breastfeeding in Spain, as well as sociocultural and perinatal factors that affect its initiation and maintenance. Design: Prospective, multicentre, longitudinal, nationwide study (XXX study). Site: Primary care paediatricians’ office. Participants: Cohort of newborns born between April 2017 and March 2018 in Spain who were followed up to two years of age in 8 visits. Main measures: Rates of different types of breastfeeding were analysed at each visit and variables related to gestation, delivery, neonatal period, social, economic and biological variables were also analysed. Results: Initial sample of 1946 (50.1% male). 90.7% decided to initiate breastfeeding at birth. Exclusive breastfeeding (EBF) was 66.4% at 15days and 35.2% at 6months. Any type of breastfeeding (total breastfeeding [TBF]) at 6months was 61.7%. Median survival from TBF was 6.0months (95%CI: 6.0-6.1). Variables related to EBF at 15days: previous children, mother's level of education, absence of illness during pregnancy, no separation of mother and child at birth, no dummy use, no nipple problems, and time of decision to breastfeed. Variables related to longer duration of TBF: relationship of parents older than 5years, no dummy use, co-sleeping at one month of life, deciding to breastfeed before pregnancy, receiving information on breastfeeding during pregnancy and using support from associations. Conclusions: Early abandonment of breastfeeding is a major problem in Western societies. There are factors that can be worked on to improve outcomes.(AU)

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)

Epidemiological and clinical characteristics and the approach to infant chickenpox in primary care.

Chickenpox is not common in the first year of life (infant varicella) and there is a lack of data on its presentation, especially in primary care. A year-long observational study (July 2015-2016) carried out by a research network of primary care pediatricians throughout Spain.Two hundred and sixty-four pediatricians gathered data from 358 cases of clinically diagnosed chickenpox in infants. The illness was considered mild in 78% of infants < 7 months compared to 65% in those aged 7 to 12 months (p = 0.0144). Fever (46%) was present in 35% of children ≤ 6 months compared to 55% in older children (p = 0.0005). The number of skin lesions was > 50 in 35% of children ≤ 6 months old compared to 47% in > 7 months (p = 0.0273). From the 2% of hospitalized children 86% were younger than 7 months. Oral antiviral treatment was given in 33% of cases ≤ 6 months compared to 18% in older patients (p = 0.0023). Doubts about administering the chickenpox vaccine at a later date were expressed by 18% of pediatricians.Conclusion: Chickenpox is considered benign, having a mild effect on most infants. There is less clinical effect in infants ≤ 6 months although this age group is hospitalized more and is prescribed more antiviral treatment. There are doubts among pediatricians about the subsequent need for vaccination. What is Known: • Chickenpox is uncommon and of uncertain evolution in the first year of life • Hospital admissions for chickenpox are more frequent in the first year of life What is New: • The course of chickenpox in the first year of life is mild, especially in infants younger than 7 months despite the fact they are hospitalized more and are treated more frequently with antivirals. Antivirals are prescribed to 1 in 4 children with chickenpox under 12 months of age. • Almost 50% of pediatricians recommend a subsequent vaccination against chickenpox especially if it occurs in the first 6 months of life.
