Physical inactivity and a sedentary lifestyle are risk factors for excess weight and obesity in childhood. It is, therefore, necessary to adopt strategies which can modify these behaviors during childhood, the age at which habits are formed. This study aimed to evaluate the impact of an educational intervention using digital media and face-to-face activities involving children, parents, and the school community on the level of physical activity and sedentary behavior among schoolchildren.

Background: Lifestyles habits such as eating unhealthy foodscommence at home and are associated with the development of obesity and comorbidities such as insulin resistance, metabolic syndrome, and chronic degenerative diseases, which are the main causes of death in adults. The present study compared changes in dietary habits, behaviors and metabolic profiles of obese children whose mothers attended at the hospital to group sessions, with those who received the usual nutritional consultation.
Methods: Randomized clinical trial, 177 mother/obese child pairs participated, 90 in the intervention group and 87 in the control group.
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.

Encouraging healthy eating habits and physical activity is the basis for preventing and treating obesity and its complications.
Objective: To evaluate how a comprehensive intervention promoting healthy eating habits and physical activities in schools affects children's metabolic biomarkers.
Aims: To evaluate the association of 64 obesity-related polymorphisms with pediatric-onset type 2 diabetes and other glucose- and insulin-related traits in Mexican children.
Methods: Case-control and case-sibling designs were followed. We studied 99 patients with pediatric-onset type 2 diabetes, their siblings (n = 101) without diabetes, 83 unrelated pediatric controls and 137 adult controls.
Aim: To estimate the heritability, parental transmission and environmental contributions to the phenotypic variation in type 2 diabetes mellitus and metabolic syndrome-related traits in families of Mexican children and adolescents.
Methods: We performed a cross-sectional study of 184 tri-generational pedigrees with a total of 1160 individuals (99 families with a type 2 diabetes mellitus proband before age 19). The family history of type 2 diabetes mellitus in three generations was obtained by interview.
Background: There is evidence of associations of single-nucleotide polymorphisms (SNPs) with type 2 diabetes (T2D) and related glycemic traits in adults, but there is a little information about such associations in youths.
Objective: The aim of this study was to evaluate the associations of SNPs in the TCF7L2, SLC16A11, and ABCA1 genes with T2D and related glycemic traits in Mexican children and adolescents.
Subjects: A total of 99 families with children with T2D (n = 327) and 83 families with children without the disease (n = 212).
Background: The obesity pandemic has now reached children, and households should change their lifestyles to prevent it.
Objective: The objective was to assess the effect of a comprehensive intervention on body mass index z-score (BMIZ) in schoolchildren.
Methods: A yearlong study was conducted at 4 elementary schools in Mexico City.
Background: Civilization has produced lifestyle changes; currently, people ingest more calories than are expended, resulting in obesity. This study assessed the association between dietary habits, physical activities, and sedentary behaviors and the risk of obesity in schoolchildren in Mexico City.
Methods: Of 1,441 children (6-12 years old) screened in elementary schools, 202 obese (BMI ≥95(th) pc) and 200 normal-weight children (BMI 25(th)- 75(th) pc), as defined by the 2000 CDC criteria, were included in a case-control study.

Background: Low-grade inflammation is the link between obesity and insulin resistance. Because physiologic insulin resistance occurs at puberty, obese pubertal children are at higher risk for insulin resistance. Excessive diets in refined carbohydrates and saturated fats are risk factors for insulin resistance, but calcium, magnesium, vitamin-D, and the omega-3 fatty acids likely protect against inflammation and insulin resistance.

Background: Mexico has the highest adult overweight and obesity prevalence in the Americas; 23.8% of children <5 years old are at risk for overweight and 9.7% are already overweight or obese.
View Article and Find Full Text PDFBackground: Medical Insurance Siglo XXI (MISXXI) in Mexico provides funds for the medical and preventive care of children from households lacking any health insurance, thus seeking to reduce impoverishing due to health problems. This paper analyzes mortality of children <2 years of age affiliated with this program and out-of-pocket expenses attributable to this event.
Methods: An in-home survey addressed to determine the health conditions of children affiliated with MISXXI was carried out in all Mexican states.
Background: Approximately 50% of obese children are insulin resistant. It has been suggested that pharmacological and nutritional options should be considered to improve the management of insulin resistance (IR).
Objective: To assess the effect of metformin (Met) or omega-3 (ω-3) polyunsaturated fatty acids (PUFA) on the homeostasis model assessment-estimated insulin resistance (HOMA-IR) index, lipid profile, and body mass index (BMI) of obese children.
Background: Recent genome wide association studies (GWAS) and previous positional linkage studies have identified more than 50 single nucleotide polymorphisms (SNPs) associated with obesity, mostly in Europeans. We aimed to assess the contribution of some of these SNPs to obesity risk and to the variation of related metabolic traits, in Mexican children.
Methods: The association of six European obesity-related SNPs in or near FTO, NPC1, ENPP1, NEGR1, GNPDA2 and MC4R genes with risk of obesity was tested in 1,463 school-aged Mexican children (N(cases) = 514; N(controls) = 949).
Background: Obesity is associated with the rise of noncommunicable diseases worldwide. The pathophysiology behind this disease involves the increase of adipose tissue, being inversely related to adiponectin, but directly related to insulin resistance and metabolic syndrome (MetS). Therefore, this study aimed to determine the relationship between adiponectin levels with each component of MetS in eutrophic and obese Mexican children.
