National Seroprevalence of in Chile, 2016-2017.

is an intracellular bacterium and the cause of the zoonotic infection, Q fever. National surveillance data on seroprevalence is currently not available for any South American country, making efforts of public health to implement strategies to mitigate infections in different at-risk groups within the population extremely challenging. In the current study, we used two commercial anti- immunoassays to screen sera collected from a sample of the Chilean population as part of a 2016-2017 national health survey ( = 5166), nationwide and age-standardized.

High levels of hsCRP are associated with carbohydrate metabolism disorder.

Aim: To determine risk parameters associated with high values of high sensitive C-reactive protein (hsCRP) in subjects with different glucose fasting levels.

Methods: Anthropometric parameters, arterial pressure, glycemia, lipid profile, uric acid, and hsCRP were studied in a population of 513 individuals between 40 and 65 years.

Results: In total, 349 (68.

Elevated concentration of asymmetric dimethylarginine (ADMA) in individuals with metabolic syndrome.

The metabolic syndrome (MS) is a cluster of pathophysiological alterations that includes the presence of hypertension, insulin resistance, dyslipidemia, and abdominal obesity. MS is associated with increased risk of developing diabetes and cardiovascular diseases. Endothelial dysfunction with impaired nitric oxide (NO) bioavailability has been implicated in insulin resistance and hypertension.

Intervention with education and exercise reverses the metabolic syndrome in adults.

About 29% of the adult population of Talca, Chile, suffers from the metabolic syndrome (MS), a value higher than the national prevalence. Evidence indicates that exercise and nutritional changes reduce the predominance of this syndrome. The goal of this study was to evaluate the effects of a structured interventional program of physical activity and nutritional counseling in adults with MS.

[Discordance between nutritional status and self perception of weight among adults from Talca, Chile].

Background: Obesity is related to underestimation of one's own weight.

Aim: To determine the agreement between nutritional status and self perception of weight status in apparently healthy adults from Talca.

Subjects And Methods: Data were obtained from a survey applied at 1007 randomly selected subjects, aged 18-74 years old (66% women).

Increased concentration of plasminogen activator inhibitor-1 and fibrinogen in individuals with metabolic syndrome.

Metabolic syndrome (MS) is closely linked to a generalized metabolic disorder referred to as insulin resistance. Disturbances in the hemostasis and fibrinolytic systems are a feature of MS. The aim of this study was to determine the concentration levels of fibrinogen and plasminogen activator inhibitor-1 (PAI-1) in a group of patients with MS with respect to a non-MS group, and to evaluate their possible relation with other risk factors in MS.

[Value of a clinical test for assessing physical activity in children].

Background: An appropriate measurement of physical activity (PA) in children is useful, since inactivity is associated to obesity, cardiovascular and metabolic risk.

Aim: To assess the reliability of the INTA questionnaire of PA, to compare the derived PA score with accelerometry and to assess its ability to identify excessively inactive children.

Material And Methods: One hundred eighty children aged 8 to 13 years answered an interviewer-administered questionnaire about their usual PA, consisting in 5 items (recumbent, seated, walking, playing outdoor, sports).

Evaluation of metabolic syndrome in adults of Talca city, Chile.

Objective: Insulin resistance (IR) is an important risk factor for type 2 Diabetes Mellitus (DM2) and cardiovascular disease (CVD). Metabolic Syndrome (MS) is a clustering of metabolic alterations associated to IR; however, there is no international consensus for defining its diagnosis. Our objective was to evaluate the prevalence and characteristics of MS identified by the ATP III and IDF criteria in adults from Talca city.

Chilean school-age children twin registry: planning, sampling and implications.

We describe subject recruitment from the University of Chile School-Age Children Twin Registry (REMEUCHI). The research aim of REMEUCHI is to quantify the impact of genetic and environmental factors on scholastic achievement in a multicausal approach. The Ministry of Education of Chile, in collaboration with the Registry Office, provided the list of possible twin pairs graduated from high school in 2004 in Chile's metropolitan region.

Protective effect of Bacillus Calmette-Guerin (BCG) vaccination in children with extra-pulmonary tuberculosis, but not the pulmonary disease. A case-control study in Rosario, Argentina.

A hospital-based case-control study was carried out at the Vilela Children's Hospital in Rosario, Argentina, to measure the protection conferred by BCG vaccination against tuberculosis (TB). The study included 148 newly diagnosed cases of TB (75 males and 73 females, mean age 3.34+/-2.

[Variations of body mass index (BMI) according to degree of pubertal development].

Background: Body mass index (BMI) is the recommended parameter to assess the nutritional status of subjects aged less than 20 years. However, during puberty the correlation between BMI and fat mass decreases notably. Therefore, the use of BMI for the diagnosis of obesity during puberty may be misleading.

[A methodological proposal to include nutrition education in primary schools. Experience in Chile].

This article presents the methodology to incorporate nutrition education in Chilean primary schools. In 2001, nutritional status, food and nutrition knowledge, attitudes and practices of 1701 school children from ten urban and rural public schools (3rd to 7th grade) were evaluated. This information was necessary to design the nutrition education strategy.

Scholastic achievement: a multivariate analysis of nutritional, intellectual, socioeconomic, sociocultural, familial, and demographic variables in Chilean school-age children.

Objective: We determined relative effects of nutritional status, intellectual ability, exposure to mass media, and socioeconomic, sociocultural, familial, demographic, and educational variables on scholastic achievement (SA).

Methods: This was a cross-sectional study. Exposure to mass media and nutritional, intellectual, socioeconomic, sociocultural, familial, demographic, and educational factors, including approximately 2000 variables, were measured in a representative and proportional sample of 4509 school-age children from elementary and high schools in Chile's Metropolitan Region.

Head size and intelligence, learning, nutritional status and brain development. Head, IQ, learning, nutrition and brain.

This multifactorial study investigates the interrelationships between head circumference (HC) and intellectual quotient (IQ), learning, nutritional status and brain development in Chilean school-age children graduating from high school, of both sexes and with high and low IQ and socio-economic strata (SES). The sample consisted of 96 right-handed healthy students (mean age 18.0 +/- 0.
