Mexican Clinical Practice Guidelines for Adult Overweight and Obesity Management.

Purpose: To develop Mexico's first methodologically rigorous clinical practice guideline for the management of adult overweight and obesity. The target audiences are interdisciplinary healthcare professionals across healthcare systems who are the first point of contact for patients with obesity in Mexico, patients, and health system decision makers.

Recent Findings: A review of recent international obesity clinical practice guidelines and an expert consensus process identified: i) common recommendations appropriate for implementation in Mexico and ii) knowledge gaps requiring the formulation of new recommendations.

Total Gestational Weight Gain Is Explained by Leptin and Body Fat, Regardless of Pre-Pregnancy Body Mass Index and Other Adipokines, in Mexican Adolescents.

Pre-pregnancy body mass index (pBMI) is a predictor of gestational weight gain (GWG). However, other factors, such as adipokines and inflammation markers, may also be associated with GWG. The aim of the study was to determine the association of leptin, adiponectin, irisin, and C-reactive protein, with GWG in adolescents.

Development and validation of a new set of indicators to assess the quality of maternal and child nutritional care at the primary care.

Introduction: Maternal and child malnutrition is a worldwide public health problem with short, medium, and long-term adverse consequences for both mother and child. In Mexico, maternal and child malnutrition represents a serious public health problem that must be urgently addressed. In this context, Primary Health Care (PHC) plays an important role in the prevention, detection, monitoring, and treatment of the different forms of maternal and child malnutrition.

The beneficial effect of a comprehensive diabetes care model on high-risk relatives accompanying patients with type 2 diabetes.

Aims: Assess the effect of a diabetes program on lifestyle, metabolic, and mental health parameters in relatives of patients with T2D, and correlate changes between relatives and patients.

Methods: Relatives were included in a structured program for patients with T2D. They received individualized interventions or were asked to follow lifestyle modifications indicated to their patient with diabetes.

Similar or different? Comparing food cultures with regard to traditional and modern eating across ten countries.

Food cultures can play a role in health and well-being. This raises the questions of whether nation boundaries unite the food cultures of different regions and ethnic groups, what characterises food cultures from very different parts of the world, and what similarities and differences exist. The present study aimed to investigate these questions with regard to eating traditions and modern eating practices.

Perceived Diet Quality, Eating Behaviour, and Lifestyle Changes in a Mexican Population with Internet Access during Confinement for the COVID-19 Pandemic: ESCAN-COVID19Mx Survey.

Perceived changes in diet quality, emotional eating, physical activity, and lifestyle were evaluated in a group of Mexican adults before and during COVID-19 confinement. In this study, 8289 adults answered an online questionnaire between April and May 2020. Data about sociodemographic characteristics, self-reported weight and height, diet quality, emotional eating, physical activity, and lifestyle changes were collected.

Examining the validity and consistency of the Adult Eating Behaviour Questionnaire-Español (AEBQ-Esp) and its relationship to BMI in a Mexican population.

Purpose: Appetitive traits in adults and their associations with weight can be measured using the Adult Eating Behaviour Questionnaire (AEBQ). The aim of this study was to confirm the factor structure of the Spanish AEBQ (AEBQ-Esp) in a Mexican sample and explore associations between the eight traits with body mass index (BMI).

Method: A sample of 1023 adults, mean age of 36.

Bioethics in Medical Care Rationing During the Coronavirus Disease-19 Pandemic.

Background: Coronavirus (CoV) disease (COVID)-19 poses difficult situations in which the ethical course of action is not clear, or choices are made between equally unacceptable responses.

Methods: A web search was performed using the terms "bioethics; COVID-19; ethics; severe acute respiratory syndrome CoV-2; emergent care; pandemic; and public health emergencies."

Results: Protection from COVID-19 has resulted in the cancellation of necessary medical interventions, lengthened suffering, and potential non-COVID-19 deaths.

Bioethics in the COVID-19 Pandemic Research: Challenges and Strategies.

As all other aspects in times of the coronavirus disease (COVID)-19 pandemic, carrying-out quality clinical research has been challenging. Many well-established paradigms have shifted as a consequence of the rapid demand for new knowledge. New treatments are fast-moving, informed consent forms are difficult to obtain, a competitive invitation from researchers to participate in different studies is common, and non-COVID-19 research protocols are suffering continuity.

[Nutricia Code: nutrition and conflict of interest in academia].

To combat malnutrition in all its forms, actions must be integrated from society as a whole. The main interest of the actors involved in these actions should be health. However, there are actors with conflict of interest that interfere in the design, planning, implementation and monitoring of public health nutrition policies.

Understanding traditional and modern eating: the TEP10 framework.

Across the world, there has been a movement from traditional to modern eating, including a movement of traditional eating patterns from their origin culture to new cultures, and the emergence of new foods and eating behaviors. This trend toward modern eating is of particular significance because traditional eating has been related to positive health outcomes and sustainability. Yet, there is no consensus on what constitutes traditional and modern eating.

Perímetro de cuello y éxito del tratamiento de pacientes con obesidad: estudio de vida real.

Introduction: Evaluation of the patient with obesity is a challenge due to the technical difficulties to carry out measurements.

Objective: To assess the association between neck circumference (NC) and waist circumference (WC) with cardio-metabolic risk markers, as well as treatment success in patients with morbid obesity.

Method: Four-hundred and seventy patients of 39.

Changes in nutrient and calorie intake, adipose mass, triglycerides and TNF-α concentrations after non-caloric sweetener intake: A pilot study.

Establishing the safety of non-caloric sweetener consumption in humans is a difficult task, since many contradictory results have been reported. The objective of this study was to compare the effect of frequent intake of sucrose, sucralose or steviol glycosides, on selected anthropometric, biochemical and immunological parameters in healthy, young adults. 38 individuals with normal body mass index were recruited and randomly divided into three experimental groups.

III. THE ROLE OF THE RESEARCH ETHICS COMMITTEES IN THE REGULATION OF PHARMA-SPONSORED STUDIES.

Participants of Pharma-sponsored research are exposed to risks, benefits, and uncertainties that do not occur in other forms of clinical studies. Ethics committees represent the subjects' first line of protection. This responsibility begins with the study review and ends after all study subjects finish the intervention.

II. THE RESEARCH ETHICS INVOLVING VULNERABLE GROUPS.

Vulnerability in research occurs when the participant is incapable of protecting his or her interests and therefore, has an increased probability of being intentionally or unintentionally harmed. This manuscript aims to discuss the conditions that make a group vulnerable and the tools and requirements that can be used to reduce the ethical breaches when including them in research protocols. The vulnerability can be due either to an inability to understand and give informed consent or to unequal power relationships that hinder basic rights.

I. THE ROLE OF RESEARCH ETHICS COMMITTEES IN OBSERVATIONAL STUDIES: EPIDEMIOLOGICAL REGISTRIES, CASE REPORTS, INTERVIEWS, AND RETROSPECTIVE STUDIES.

It is often unclear to the clinical investigator whether observational studies should be submitted to a research ethics committee (REC), mostly because, in general, no active or additional interventions are performed. Moreover, obtaining an informed consent under these circumstances may be challenging, either because these are very large epidemiological registries, or the subject may no longer be alive, is too ill to consent, or is impossible to contact after being discharged. Although observational studies do not involve interventions, they entail ethical concerns, including threats such as breaches in confidentiality and autonomy, and respect for basic rights of the research subjects according to the good clinical practices.

Ethnic differences in fat and muscle mass and their implication for interpretation of bioelectrical impedance vector analysis.

According to the World Health Organization Expert Consultation, current body mass index (BMI) cut-offs should be retained as an international classification. However, there are ethnic differences in BMI-associated health risks that may be caused by differences in body fat or skeletal muscle mass and these may affect the interpretation of phase angle and bioelectrical impedance vector analysis (BIVA). Therefore, the aim of this study was to compare body composition measured by bioelectrical impedance analysis among 1048 German, 1026 Mexican, and 995 Japanese adults encompassing a wide range of ages and BMIs (18-78 years; BMI, 13.

[A front-of-pack labelling system for food and beverages for Mexico: a strategy of healthy decision-making.].

The Mexican Ministry of Health requested the National Institute of Public Health to constitute a group of independent, free of conflict-of-interest academic experts on front-of-pack labelling (FOP). This group was instructed to created a positioning paper to contribute to the development of a FOP system for industrialized products that offers useful information for purchase decision making. This position paper uses the best available scientific evidence, and recommendations from experts of international organizations.

Eating behavior and psychological profile: associations between daughters with distinct eating disorders and their mothers.

Background: Associations of eating behaviors and psychological profile between mothers and daughters with eating disorders exist, but it is important to dissect the influence of the mother in each specific disorder since all eating disorders must be seen or treated not as one entity. The aim of the present study was to evaluate the association of eating behavior and psychological profile between mothers and daughters with different eating disorders and a control group.

Methods: The study group included young girls with anorexia nervosa (AN, n = 30), bulimia nervosa (BN, n = 30), binge eating disorder (BED, n = 19), and a control group of women (Non-ED, n = 54) together with their mothers.

Weight Loss Success Among Overweight and Obese Women of Mexican-Origin Living in Mexico and the United States: A Comparison of Two National Surveys.

We assessed variations in and correlates of weight-loss success (WLS) among overweight/obese women in Mexico (WIMX) and Mexican-American women (MA). We used cross-national data from 2006 ENSANUT (Mexico) and NHANES (2001-2008) to compare 5061 WIMX with 550 MA's without known metabolic conditions. WLS was defined as losing ≥5 % of body weight over 1 year.
