Relationship between eating habits, sleep patterns and physical activity and the degree of obesity in children and adolescents.

Introduction: Childhood obesity is an extremely prevalent pathology and, in order to be able to address it, it is necessary to understand the factors that influence on its genesis and maintenance. We hypothesise that the timing of meals and sleep, the regularity of these throughout the week and a sedentary lifestyle influence the degree of obesity.

Material And Methods: We included children and adolescents with obesity who attended a first check-up visit at the Childhood Obesity Unit between January 2018 and February 2020.

Prevalence and risk factors associated with different comorbidities in obese children and adolescents.

Introduction: Different obesity-related comorbidities already present in childhood, such as: vitamin D deficiency, impaired carbohydrate metabolism, dyslipidaemia, arterial hypertension and non-alcoholic steatohepatitis. In this study, we aim to analyse the prevalence of comorbidities and to determine the predictive factors that affect these comorbidities.

Material And Methods: Anthropometric, demographic and biochemical variables were collected from obese patients between six and 18 years of age.

Children with type 1 diabetes have elevated high-sensitivity C-reactive protein compared with a control group.

Introduction: Our objective was to compare high-sensitivity C-reactive protein (hsCRP) levels in children with type 1 diabetes, healthy controls, and children with obesity. Additionally, we aimed to analyze the association between hsCRP levels and glycemic control measured by glycohemoglobin A (HbA1c) and anthropometric and biochemical variables.

Research Design And Methods: We conducted a non-randomized descriptive study of children with type 1 diabetes matched for sex and age with a control group and group with obesity.

Clinical Exome Sequencing Reveals MKRN3 Pathogenic Variants in Familial and Nonfamilial Idiopathic Central Precocious Puberty.

Background/aims: Idiopathic central precocious puberty (ICPP) is the premature activation of the hypothalamic-pituitary-gonadal axis in the absence of organic disease. Up to now, just gain-of-function mutations of KISS1/KISS1R and loss-of-function mutations of the maternally imprinted gene MKRN3 are the known genetic causes of ICPP. Our intention is to evaluate variants present in genes related to the pubertal onset pathway that could act as disease-causing or predisposing variants.

[The relationship between metabolic disorders and small for gestational age with idiopathic premature adrenarche].

Background: There is still controversy on the relationship between idiopathic premature adrenarche (IPA) and a history of small for gestational age, as well as the concomitant presence of obesity and other metabolic disturbances. An attempt is made to study these potential associations in a cohort of girls with IPA from our hospital.

Patients And Methods: A descriptive cross-sectional study was conducted that included girls with a diagnosis of IPA from the Paediatric Department of the Fundación Jiménez Díaz (Madrid, Spain) between January 2007 and May 2015.
