Heuristic evaluation of body mass index with bioimpedance data in the Mexican population.

Introduction: given the problematic battle against cardio-metabolic diseases and the increase in computational power, different applications are being developed to help estimate overweight and obesity in the population. Objectives: to evaluate the body mass index (BMI) formula (kg/m2), taking body fat measured by bioimpedance as a reference and comparing it with variations of the same form obtained by applying algebraic transformation rules using an artificial intelligence heuristic search method. Material and methods: an artificial intelligence heuristic method was applied to search for the formula that most accurately calculates people's body fat percentage.

Enhanced Stature in the Elderly: The Immediate Impact of Acute Postural Exercises.

This study investigates the immediate effects of acute postural exercises on the stature of seniors, focusing on changes in both upright and supine stature measurements. A within-subject design with repeated measures was applied, involving seniors participating in continuous exercises aimed at enhancing core musculature strength and promoting muscle relaxation. Stature measurements were recorded pre- and post-exercise in both upright and supine positions, alongside assessments of body mass index (BMI) category classifications.

Anthropometric Equations to Determine Maximum Height in Adults ≥ 60 Years: A Systematic Review.

Although it is common to measure bone lengths for study, methodological errors in data measurement and processing often invalidate their clinical and scientific usefulness. This manuscript reviews the validity of several published equations used to determine the maximum height in older adults, since height is an anthropometric parameter widely employed in health sciences. A systematic review of original articles published in the English, Spanish, or Portuguese languages was performed in PubMed, ScienceDirect, EBSCO, Springer Link, and two institutional publisher integrators (UACJ and CONRICYT).

Oxidative Damage by 3-nitrotyrosine in Young Adults with Obesity: Its Implication in Chronic and Contagious Diseases.

Introduction: Cellular damage by oxidation occurs in numerous chronic diseases, such as obesity, type II diabetes, cardiovascular disease, nonalcoholic fatty liver, etc. The oxidized compound 3-nitrotyrosine is a marker of oxidative stress and protein oxidation damage.

Objective: The article aims to assess whether 3-nitrotyrosine levels are higher in young people with obesity than in the same population without obesity.

CARDIOMETABOLIC RISK FACTORS ASSOCIATED WITH RENAL FUNCTION IN APPARENTLY HEALTHY YOUNG STUDENTS: A CROSS-SECTIONAL STUDY.

Background: Cardiometabolic risk factors (CMRFs) appear decades before developing chronic kidney disease (CKD) in adulthood.

Objective: The objective of the study was to identify the prevalence and association between CMRFs and kidney function in apparently healthy young adults (18-25 years old).

Methods: We included 5531 freshman year students.

Denitrase activity of reduces the oxidized compound 3-nitrotyrosine in mice liver with colitis.

The oxidation of tyrosine to 3-nitrotyrosine is irreversible, and due to this characteristic, 3-nitrotyrosine is used as a marker for oxidative stress in a range of diverse chronic and degenerative diseases. It has been established that the yeast can assimilate free 3-nitrotyrosine as unique source of nitrogen, and during saline stress, has a high denitrase activity to detoxify this compound in a reaction that involves the liberation of nitrogen dioxide from 3-nitrotyrosine. However, until now it has not been determined whether can detoxify protein-bound 3-nitrotyrosine such as nitrated proteins present in different chronic illnesses.

Clinical Significance of Serum Uric Acid Levels in Mexican Young Adults.

Background: High serum uric acid concentration (SUA >6 for women [W] or 7 mg/dL for men [M]) in adults is an independent risk factor for causing cardiovascular disease and chronic kidney disease (CKD); the risk of high SUA in young population is still being debated.

Summary: We conducted an epidemiological study to determine the association between SUA quartiles with cardiometabolic risk factors (CRF) and renal impairment in apparently healthy young adults. CRF (dyslipidemia, overweight [Ow], obesity [Ob], blood pressure [BP], hyperglycemia, insulin resistance [IR]) and renal impairment were defined as glomerular filtration rate (GFR) by CKD-Epidemiology Collaboration formula >130/120, <90 mL/min/1.

Prevalence of bullying by gender and education in a city with high violence and migration in Mexico.

Objective: To understand the prevalence of bullying, by gender and educational level, in Ciudad Juárez, Mexico, a city with high rates of violence and migration.

Methods: This was a cross-sectional, observational study conducted in 2012 - 2014 using a questionnaire known as the Bullying-Mexican. A probabilistic multistage cluster-sampling method obtained a study sample of 2 347 students (10 - 27 years of age) from the 400 000 enrolled in grade 5 - university level at the 611 public schools in Ciudad Juárez.

Abdominal obesity is strongly associated to blood pressure in young Mexicans.

Objective: The objective of this study was to determine associations between abdominal obesity (AOb) and the other components of metabolic syndrome (MetS) in young Mexicans in a cross-sectional survey completed during a 4 year period.

Methods: This cross-sectional study reports on components and prevalence of MetS by using Alberti et al. (16) criteria, as well as association between AOb and elevated blood pressure (BP) of 2,993 Mexican university students, ages 17 to 25 years (66% women) from central and northern Mexico, over a 4-year survey (2010-2013).

Fasting Triglycerides and Glucose Index as a Diagnostic Test for Insulin Resistance in Young Adults.

Background And Aims: Although the Glucose and Triglyceride levels (TyG) index is useful for identification of insulin resistance (IR) in different ethnic groups, it has not been evaluated in young adults. We undertook this study to evaluate the TyG index as a diagnostic test for IR in young adults.

Methods: A total of 5,538 healthy young adults, 3,795 (68.

Cardiometabolic risk in young adults from northern Mexico: Revisiting body mass index and waist-circumference as predictors.

Background: A body mass index (BMI) ≥30 kg/m(2) and a waist circumference (WC) ≥80 cm in women (WCF) or ≥90 cm in men (WCM) are reference cardiometabolic risk markers (CMM) for Mexicans adults. However, their reliability to predict other CMM (index tests) in young Mexicans has not been studied in depth.

Methods: A cross-sectional descriptive study evaluating several anthropometric, physiological and biochemical CMM from 295 young Mexicans was performed.

PREVALENCE OF METABOLIC SYNDROME IN YOUNG MEXICANS: A SENSITIVITY ANALYSIS ON ITS COMPONENTS.

Introduction: obesity is a worldwide epidemic, and the high prevalence of diabetes type II (DM2) and cardiovascular disease (CVD) is in great part a consequence of that epidemic. Metabolic syndrome is a useful tool to estimate the risk of a young population to evolve to DM2 and CVD.

Objective: to estimate the MetS prevalence in young Mexicans, and to evaluate each parameter as an independent indicator through a sensitivity analysis.

Plasma triglyceride/HDL-cholesterol ratio, insulin resistance, and cardiometabolic risk in young adults.

Studies in mature adults suggest that the plasma concentration ratio of triglyceride (TG)/HDL-cholesterol (HDL-C) provides a simple way to identify apparently healthy individuals who are insulin resistant (IR) and at increased cardiometabolic risk. This study extends these observations by examining the clinical utility of the TG/HDL-C ratio and the metabolic syndrome (MetS) in 2,244 healthy college students (17-24 years old) of Mexican Mestizo ancestry. The TG/HDL-C ratio separating the 25% with the highest value was used to identify IR and increased cardiometabolic risk.

Estimating the geographical distribution of the prevalence of the metabolic syndrome in young Mexicans.

The geographical distribution of the metabolic syndrome (MetS) prevalence in young Mexicans (aged 17-24 years) was estimated stepwise starting from its prevalence based on the body mass index (BMI) in a study of 3,176 undergraduate students of this age group from Mexico City. To estimate the number of people with MetS by state, we multiplied its prevalence derived from the BMI range found in the Mexico City sample by the BMI proportions (range and state) obtained from the Mexico 2006 national survey on health and nutrition. Finally, to estimate the total number of young people with MetS in Mexico, its prevalence by state was multiplied by the share of young population in each state according to the National Population and Housing Census 2010.
