Activity of the antioxidant enzyme paraoxonase in Argentinean children living at high altitude.

Background: Children living at high altitude in San Antonio de los Cobres (SAC), Argentina, were shown to have lower high-density lipoprotein cholesterol (HDL-C) levels than Buenos Aires (BA) children. HDL antioxidant capacity is mainly attributed to paraoxonase1 (PON1).

Objective: To compare PON1 activity in indigenous SAC vs.

Association between Apo B Levels in Mothers and in their Pre-school Age Offspring.

Objective: The study aims to determine the association between apo B levels in mothers and their pre-school offspring.

Methods: Anthropometric measurement (e.g.

Association between left atrial size and measures of adiposity among normal adolescent boys.

Obesity (OB) in adults is associated with insulin resistance, hypertension, and left atrial (LA) enlargement. This study aimed to determine the association between LA size and (1) different components of the metabolic syndrome (body mass index [BMI], waist circumference [WC], insulin levels, lipid levels, and blood pressure), and (2) left ventricular (LV) diameters and diastolic function. Data were collected cross-sectionally from 142 healthy adolescent boys age 16.

Comparison of different anthropometric indices for identifying dyslipidemia in school children.

Background: Anthropometric indices have been associated with dyslipidemia.

Objective: To compare the abilities of BMI, waist circumference (WC) and WC/height to identify children's dyslipidemia.

Methods: Students 1261 (639 male) age 9.

Relationship between obesity and metabolic syndrome among Argentinean elementary school children.

Background: Argentina has experienced marked increases in the prevalence of childhood overweight (OW)/obesity over the last few decades.

Objectives: We examined (1) the distribution of the mean values of lipids, glucose, and HOMA-IR according to the presence of OW/obesity, age, and sex and (2) the association between metabolic syndrome and OW/obesity, Tanner stage, gender, and HOMA-IR.

Methods: Data were collected from 1009 children (508 males) in 10 elementary schools between April and September 2007.
