Examining for an association between candidate gene polymorphisms in the metabolic syndrome components on excess weight and adiposity measures in youth: a cross-sectional study.

Background: A polymorphism in a gene may exert its effects on multiple phenotypes. The aim of this study is to explore the association of 10 metabolic syndrome candidate genes with excess weight and adiposity and evaluate the effect of perinatal and socioeconomic factors on these associations.

Methods: The anthropometry, socioeconomic and perinatal conditions and 10 polymorphisms were evaluated in 1081 young people between 10 and 18 years old.

Variant in CAPN10 gene and environmental factors show evidence of association with excess weight among young people in a Colombian population.

Unlabelled: Introduction : Obesity results from interaction between genetic and environmental risk factors.

Objective: To evaluate the effect of three gene variants and environmental factors on obesity and overweight in young people aged 10 to 18 years in a Colombian population.

Materials And Methods: A total of 424 subjects were selected and separated into three groups for a cross-sectional study; 100 obese and 112 overweight subjects were matched with 212 normal-weight controls.

The gut microbiota of Colombians differs from that of Americans, Europeans and Asians.

Background: The composition of the gut microbiota has recently been associated with health and disease, particularly with obesity. Some studies suggested a higher proportion of Firmicutes and a lower proportion of Bacteroidetes in obese compared to lean people; others found discordant patterns. Most studies, however, focused on Americans or Europeans, giving a limited picture of the gut microbiome.

Variations in the prevalence of metabolic syndrome in adolescents according to different criteria used for diagnosis: which definition should be chosen for this age group?

Background: Despite the increasing prevalence of metabolic syndrome in adolescents, there is no consensus for its diagnosis.

Methods: A cross-sectional study was conducted to compare the prevalence of metabolic syndrome in adolescents by different definitions, evaluate their concordance, and suggest which definition to apply in this population. A total of 851 adolescents between 10 and 18 years of age were evaluated.

[Environmental risk factors and metabolic syndrome components in overweight youngsters].

Introduction: The environmental risk factors such as food intake and physival activity, are determinants in the etiology of metabolic syndrome in overweight adolescents.

Objective: To explore the association between environmental risk factors and components presence of metabolic syndrome in overweight youngsters in Medellín.

Materials And Methods: Adolescents between the ages of 10 and 18 were selected for a cross sectional study.

Incidence of nutritional support complications in patient hospitalized in wards. multicentric study.

Introduction: Nutritional support generates complications that must be detected and treated on time.

Objective: To estimate the incidence of some complications of nutritional support in patients admitted to general hospital wards who received nutritional support in six high-complexity institutions.

Methods: Prospective, descriptive and multicentric study in patients with nutritional support; the variables studied were medical diagnosis, nutritional condition, nutritional support duration, approach, kind of formula, and eight complications.

[Nutritional condition in patients with Alzheimer-type dementia from the neurosciences' group, Medellín 2004].

Introduction: Patients suffering clinical dementia caused by Alzheimer's disease have a high risk of developing malnutrition caused by all the physiological, socio-economic and psychological changes related to the disease, together with the ageing process.

Objective: To describe the nutritional condition of a group of patients with Alzheimer's dementia according to the degree of disease severity. Patients were selected from the University of Antioquia Neurosciences Group.

Long-term nutritional and digestive consequences of pelvic radiation.

Objective: To study long-term changes in nutritional status and gastrointestinal (GI) functions of 15 women previously treated with radiotherapy for gynecological cancer. Two years prior to this research, these patients had been assessed twice: before external radiotherapy and 5 weeks later, at the completion of the external dose (45-50 Gy).

Methods: Each patient was given complete clinical evaluation, consisting of dietary, physical activity and digestive symptoms questionnaires.

[Prevalence of iron-deficiency anemia in schoolchildren and adolescents, Medellín, Colombia, 1999].

Objective: This research had two objectives: (1) to determine the prevalence of iron-deficiency anemia and describe iron consumption in the diet of schoolchildren and adolescents enrolled in public and private schools of the urban area of the city of Medellín, Colombia, in the 1999-2000 school year and (2) to explore the associations that age group, sex, socioeconomic class, and intestinal parasitism show with iron-deficiency anemia and iron deficiency.

Methods: A cross-sectional study was carried out among 960 students from 6 to 18 years old who were selected by simple random sampling after stratified multistage sampling and clustering in public and private schools in districts of Medellín. Body iron content was evaluated by determining ferritin and hemoglobin levels, average corpuscular volume, and amplitude of the erythrocyte distribution; the presence of intestinal parasites was evaluated through stool analysis; nutritional status was evaluated by means of anthropometric measurements; and consumption of iron and vitamin C was evaluated using a semiquantitative questionnaire on food intake.
