[Breastfeeding in Spain and the factors related to its establishment and maintenance: LAyDI Study (PAPenRed)].

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.

Predictive capacity for breastfeeding and determination of the best cut-off point for the breastfeeding self-efficacy scale-short form.

Introduction: The most widely used tool for assessing breastfeeding self-efficacy is the Breastfeeding Self-Efficacy Scale-Short Form (BSES-SF). This study assesses the relationship between the BSES-SF score and the risk of breastfeeding (BF) cessation and determines 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.

Evolution of bone mineral density in patients with idiopathic hypercalciuria: a 20-year longitudinal study.

Background: Several recent studies reported bone mineral density (BMD) reduction in pediatric patients with idiopathic hypercalciuria (IH). This longitudinal study aimed to evaluate BMD evolution in IH patients through three bone densitometry studies conducted over 20 years on average. A second objective was to evaluate urine calcium and citrate excretion during this period.

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.
