Malnutrition prevalence among children and women of reproductive age in Mexico by wealth, education level, urban/rural area and indigenous ethnicity.

Objective: To compare the prevalence of malnutrition (undernutrition and excess weight) by wealth, education level, ethnicity and urban/rural areas in Mexican children and women of reproductive age.

Design: We compared the prevalence of overweight, obesity, wasting/underweight, stunting/short stature and anaemia by socioeconomic and ethnic indicators. For each indicator, we estimated prevalence ratios (PR) adjusted by all other socioeconomic and ethnic indicators.

ADIPOQ and ADIPOR2 gene polymorphisms: association with overweight/obesity in Mexican children.

Background: ENSANUT 2012 showed a combined prevalence of overweight and obesity of 34.4% in Mexican children. Single nucleotide polymorphisms (SNPs) of the ADIPOQ and ADIPOR2 genes have been reported in many populations, but their association with obesity has not been confirmed in other studies.

Leisure-time physical activity and cardiometabolic risk among children and adolescents.

Objective: To assess the effect of Leisure-time physical activity (LTPA) on cardiometabolic risk by nutritional status in Mexican children and adolescents.

Methods: This was a cross-sectional study conducted with 1,309 participants aged between 5 and 17 years. Nutritional status was classified according to the BMI Z-score by age and gender.

Association of β1 and β3 adrenergic receptors gene polymorphisms with insulin resistance and high lipid profiles related to type 2 diabetes and metabolic syndrome.

Background: Among the diverse genes associated to type 2 diabetes (T2D), the β-adrenergic receptors are an excellent candidate to study in Mexican population. The objective of this work was to analyze the association of polymorphisms in ADRB1 (rs1801253) (Arg389Gly) and ADRB3 (Trp64Arg) genes with T2D and metabolic syndrome (MS).

Methods: We studied 445 MS patients, 502 with T2D and 552 healthy controls.

[Genetics of pediatric obesity].

Obesity is a major health problem around the globe. The statistics of overweight and obesity at early ages have reached alarming levels and placed our country in the first place in regard to childhood obesity. In the development of obesity two major factors take part, one genetic and the other one environmental.

[Childhood obesity is associated to the interaction between firmicutes and high energy food consumption].

Unlabelled: INTRODUCTIÓN: Obesity is a serious public health problem in Mexico, the National Health and Nutrition Survey (ENSANUT 2012) reported a 34.4% prevalence of overweight, and obesity in children aged 5-11. Recent research has suggested that the gut microbiota may be a risk factor of obesity through its influence on human metabolism.

A replication study of the IRS1, CAPN10, TCF7L2, and PPARG gene polymorphisms associated with type 2 diabetes in two different populations of Mexico.

Type 2 diabetes (T2D) is a chronic degenerative disease that involves the participation of several genetic and environmental factors. The objective of the study was to determine the association of the IRS1 (rs1801278), CAPN10 (rs3792267), TCF7L2 (rs7903146 and rs12255372), and PPARG (rs1801282) gene polymorphisms with T2D, in two different Mexican populations. We conducted a case-control replication study in the state of Guerrero and in Mexico City, with 400 subjects from Guerrero and 1065 from Mexico City.
