Background: Childhood obesity is a significant public health concern in Mexico, with far-reaching implications for the nation's healthcare system and economy. In light of this challenge, our study sought to validate the Childhood Family Mealtime Questionnaire (CFMQ) in Mexican adolescents living with obesity and their primary caregivers.

Methods: A sample of 56 adolescents ages 13 to 17 years and their primary caregivers from one pediatric obesity clinic participated in the study.

Metabolomic Phenotype of Hepatic Steatosis and Fibrosis in Mexican Children Living with Obesity.

: Metabolic-dysfunction-associated steatotic liver disease or MASLD is the main cause of chronic liver diseases in children, and it is estimated to affect 35% of children living with obesity. This study aimed to identify metabolic phenotypes associated with two advanced stages of MASLD (hepatic steatosis and hepatic steatosis plus fibrosis) in Mexican children with obesity. : This is a cross-sectional analysis derived from a randomized clinical trial conducted in children and adolescents with obesity aged 8 to 16 years.

Barriers in the Management of Obesity in Mexican Children and Adolescents through the COVID-19 Lockdown-Lessons Learned and Perspectives for the Future.

Unlabelled: The COVID-19 lockdown caused health system issues, including the need for long-term care for patients with conditions like childhood obesity. We wanted to know how the lockdown had changed our patients' health and which variables had greater influence in preventing and managing overweight and obesity in kids and teens during and after the lockdown.

Methods: Our study comprised two phases.

Evaluation of height prediction models: from traditional methods to artificial intelligence.

Background: Traditional methods for predicting adult height (AHP) rely on manual readings of bone age (BA). However, the incorporation of artificial intelligence has recently improved the accuracy of BA readings and their incorporation into AHP models.

Methods: This study aimed to identify the AHP model that fits the current average height for adults in Mexico.

The CCR2 Monocyte Subsets Increase in Obese Boys but Not Girls with Abnormally High Carotid Intima-Media Thickness: A Pilot Study.

The differential contribution of monocyte subsets expressing the C-C chemokine receptor 2 (CCR2) to subclinical atherosclerosis in girls and boys is unclear. In this pilot study, we compared classical, intermediate, and nonclassical monocyte subsets expressing CCR2 in 33 obese children of both sexes aged 8 to 16 divided by carotid intima-media thickness (IMT), considering values above the 75th percentile (p75) as abnormally high IMT. Obesity was defined as body mass index above the 95th percentile according to age and sex.

Al proceso de desarrollo y discusión de este grupo se sumaron más de 1 000 profesionales de la salud para retomar recomendaciones de documentos y guías de alto nivel previamente publicados.

The utility of the Edmonton Obesity Staging System for the prediction of COVID-19 outcomes: a multi-centre study.

Background: Patients with obesity have an increased risk for adverse COVID-19 outcomes. Body mass index (BMI) does not acknowledge the health burden associated this disease. The performance of the Edmonton Obesity Staging System (EOSS), a clinical classification tool that assesses obesity-related comorbidity, is compared with BMI, with respect to adverse COVID-19 outcomes.

Comparison of Carotid Intima-Media Thickness in Children and Adults With and Without Obesity: A Hysteresis Model.

Objective: To describe a third-degree polynomial function (hysteresis) of the effect size of age, obesity, and insulin sensitivity over the carotid intima-media thickness (c-IMT), in the pediatric and adult groups.

Methods: A quasi-experimental study with fixed factor analysis of age (children aged 8-12 years, n = 73; adults aged 21-45 years, n = 82) and obesity (yes, n = 76; no, n = 79) was conducted to analyze the effect on the c-IMT and Matsuda insulin sensitivity index values. This quasi-experimental design was analyzed with robust regression modeling.

Association between neck circumference and non-alcoholic fatty liver disease in Mexican children and adolescents with obesity.

Background Non-alcoholic fatty liver disease (NAFLD) is the most prevalent chronic hepatic disorder in the pediatric population and has grown along with the obesity pandemic in which we live today. Adipose tissue storage in the upper body segment has been positively correlated with visceral adiposity and metabolic disease, which suggests that neck circumference could represent an easily accessible and replicable anthropometric measurement to identify patients with a higher risk of developing NAFLD. The main purpose of this study is to determine if there is an association between neck circumference and NAFLD.

Isomers of conjugated linoleic acid induce insulin resistance through a mechanism involving activation of protein kinase Cε in liver cells.

Conjugated linoleic acid (CLA) constitutes a group of isomers derived from linoleic acid. Diverse studies have suggested that these unsaturated fatty acids have beneficial effects on human health. However, it has also been reported that their consumption can generate alterations in hepatic tissue.

PEDIATRIC VISCERAL ADIPOSITY INDEX ADAPTATION CORRELATES WITH HOMA-IR, MATSUDA, AND TRANSAMINASES.

Objective: Visceral adiposity index (VAI) is a mathematical model associated with cardiometabolic risk in adults, but studies on children failed to support this association. Our group has proposed a pediatric VAI model using pediatric ranges, but it has not yet been evaluated and needs further adjustments. The objective of this study was to further adjust the proposed pediatric VAI by age, creating a new pediatric metabolic index (PMI), and assess the correlation of the PMI with insulin resistance indexes and hepatic enzymes.

Effects of Conjugated Linoleic Acid and Metformin on Insulin Sensitivity in Obese Children: Randomized Clinical Trial.

Context: Insulin resistance precedes metabolic syndrome abnormalities and may promote cardiovascular disease and type 2 diabetes in children with obesity. Results of lifestyle modification programs have been discouraging, and the use of adjuvant strategies has been necessary.

Objective: This study aimed to evaluate the effects of metformin and conjugated linoleic acid (CLA) on insulin sensitivity, measured via euglycemic-hyperinsulinemic clamp technique and insulin pathway expression molecules in muscle biopsies of children with obesity.

Velocardiofacial syndrome in Mexican patients: Unusually high prevalence of congenital heart disease.

Introduction: Velocardiofacial syndrome (VCFS) is the most common microdeletion syndrome with an incidence of 1:4000 live births. Its phenotype is highly variable with facial, velopharyngeal, cardiac, endocrine, immunologic and psychiatric abnormalities. It is caused by a microdeletion in chromosome 22q11.

Epidemiology of type 1 diabetes in Latin America.

Latin America is among the regions with the highest diabetes-related burden. Research and treatment programs have increased in number and complexity in recent years, but they are focused in type 2 diabetes, because this condition explains a large proportion of the cases. In contrast, the information regarding the epidemiology of type 1 diabetes is scant in this area.

Relationship between aminotransferases levels and components of the metabolic syndrome among multiethnic adolescents.

Methods: A sample (N = 284) of multiethnic (75% Latino, 25% Afro Caribbean/non-Hispanic black) overweight children/ adolescents' (mean age 12.24 +/- 3.

Higher metabolic syndrome in obese asthmatic compared to obese nonasthmatic adolescent males.

Unlabelled: The relationship between asthma and obesity has been documented in children and adolescents; however, few studies on metabolic syndrome and asthma have been performed.

Objective: To determine the prevalence of metabolic syndrome in adolescents among the following groups: obese with asthma (OA), obese without asthma (ONA), nonobese with asthma (NOA), and nonobese without asthma (NONA).

Patients And Methods: The authors measured anthropometric (height, weight, waist circumference, body mass index, and waist-hip ratio), clinical (Tanner stage, blood pressure, fat and muscle reserve, and exercise), and biochemical parameters (basal and load glucose, cholesterol, triglycerides, high-density lipoproteins, uric acid, and insulin) in 500 Mexican adolescents.

How do different indices of obesity correlate with cardiometabolic disease risk factors in multiethnic youths?

Objective: To investigate the relationship between cardiometabolic disease risk factors (CDRFs) among ethnic minorities and anthropometric factors including body mass index z score, waist circumference (WC), waist-to-hip ratio (WHR), and waist-to-height ratio (WHTR) in Hispanic and non-Hispanic black youths originating primarily from Central America, South America, and the Caribbean.

Methods: Clinical data of 167 young persons 2 to 19 years of age encountered in an outpatient pediatric endocrinology clinic were analyzed. The CDRFs included fasting insulin and glucose, homeostasis model assessment of insulin resistance (HOMA-IR), systolic blood pressure (SBP) and diastolic blood pressure (DBP), high-density lipoprotein cholesterol, triglycerides, cardiac C-reactive protein (CRP), and apolipoproteins.
