BODYFAT: a new calculator to determine the risk of being overweight validated in Spanish children between 11 and 17 years of age.

Unlabelled: The assessment of body fat of children in primary care requires consideration of the dynamic changes in height, weight, lean mass, and fat mass during childhood growth. To achieve this, we aim to develop a predictive equation based on anthropometric values, with optimal diagnostic utility. This is a cross-sectional observational study, involving schoolgoers aged 11-17 years in the Vigo metropolitan area.

Interrupted Time Series Analysis of Pediatric Infectious Diseases and the Consumption of Antibiotics in an Atlantic European Region during the SARS-CoV-2 Pandemic.

The increasing concern about bacterial resistance has made the rational prescription of antibiotics even more urgent. The non-pharmacological measures established to reduce the impact of the SARS-CoV-2 pandemic have modified the epidemiology of pediatric infections and, consequently, the use of antibiotics. Interrupted time series (ITS) analyses are quasi-experimental studies that allow for the estimation of causal effects with observational data in "natural experiments", such as changes in health policies or pandemics.

[Early detection of the problematic Internet use in adolescents, in pediatrics of primary care.].

Objective: Use of the Internet has grown exponentially and adolescents are considered one of the most vulnerable groups in this new environment. Hence the problematic use of the Internet (PIU) at this stage has become a concern for a growing number of researchers. Taking into account the interest that this issue has generated at many levels, the aim of this paper is to find the prevalence of PIU among adolescents in the health area of Vigo (Spain).

[Prevalence of neurodevelopmental, behavioural and learning disorders in Pediatric Primary Care].

Objectives: To determine the prevalence of psychiatric disorders in primary care pediatrics in Atlantic Galicia.

Methods: An observational, descriptive, cross-sectional prevalence study was carried out in 9 outpatient clinics in A Coruña and Pontevedra with a population of 8293 children between September and November 2015. A total of 1286 randomly selected patients from 0 to 14 years of age were included.

[High levels of atrial natriuretic peptide and copeptin and mortality risk].

Objective: To determine whether high levels of mid-regional pro-atrial natriuretic peptide (MR-proANP), copeptin, and procalcitonin (PCT) plasma concentrations are associated with increased mortality risk.

Methods: Prospective observational study including 254 critically ill children. MR-proANP, copeptin and PCT were compared between children with high (Group A; n=33) and low (Group B; n=221) mortality risk, and between patients with failure of more than 1 organ (Group 1; n=71) and less than 2 (Group 2; n=183).
