Multiple cardiovascular risk factors in adolescents from a middle-income country: Prevalence and associated factors.

Multiple cardiovascular risk factors are directly related to the severity of atherosclerosis, even in children and adolescents. In this context accurate assessment of risk factors at the individual level play a decisive role in cardiovascular disease (CVD) prevention. The objective of this study was to estimate the prevalence of cardiovascular risk factors, the frequency of their coexistence in individuals, and identify possible determinants associated with this coexistence in Brazilian adolescents.

White-coat, masked and sustained hypertension detected by home blood pressure monitoring in adolescents: prevalence and associated factors.

Purpose: Population-based studies estimating prevalence's of white-coat, masked and sustained hypertension in non-European adolescents are needed, particularly in developing countries. Aiming to determine these estimates and, additionally identify factors associated to these conditions this study was conducted.

Materials And Methods: Cross-sectional study with a representative sample of secondary school students from a Brazilian state capital.

Birth weight and its association with blood pressure and nutritional status in adolescents.

Objective: The management of children with low birth weight is not the same in countries with different resources. The authors assessed the association of birth weight with blood pressure and nutritional status in a representative sample of adolescents from a Brazilian state, aiming to identify possible consequences of these differences.

Methods: A cross-sectional school-based study was conducted with adolescents (12-18 years) enrolled in public and private schools.

Overweight and associated factors in adolescents from a brazilian capital.

Objective:: To evaluate the prevalence of overweight in adolescents and its associated factors.

Methods:: A cross-sectional study in public and private schools in Goiania, Brazil. Socioeconomic status, family history of obesity, lifestyle, blood pressure and Body Mass Index were studied in a sample of 1,169 Brazilian youth aged 12 - 18 years, who attended public and private schools.

Home Blood Pressure Monitoring as an Alternative to Confirm Diagnoses of Hypertension in Adolescents with Elevated Office Blood Pressure from a Brazilian State Capital.

Background: Regional differences of using home blood pressure monitoring (HBPM) as an alternative to ambulatory blood pressure monitoring (ABPM) in hypertensive adolescents are unknown.

Objectives: Define if HBPM is an option to confirm diagnoses of hypertension in adolescents from a Brazilian capital with elevated office blood pressure (BP).

Methods: Adolescents (12-18years) from public and private schools with BP > 90th percentile were studied to compare and evaluate the agreement among office BP measurements, HBPM and ambulatory BP monitoring.

Home blood pressure normalcy in non-European adolescents.

Objective: Evidence on normal range of home blood pressure (BP) in adolescents relies on only one European study. This study aims to investigate the normal range of home BP in a healthy non-European population of adolescents.

Methods: Cross-sectional study with a representative sample of secondary school students (12-17 years) from a Brazilian state capital.

Office blood pressure measurements with oscillometric devices in adolescents: a comparison with home blood pressure.

Purpose: Compare multiple in office BP measurements in adolescents using an oscillometric device with out-of-office blood pressure measurements (home blood pressure monitoring - HBPM).

Materials And Methods: Office measurements were performed with validated semi-automatic devices twice (3 minutes interval) in two different moments (1 week apart), with a total of four readings. These BP readings were named R1, R2, R3 and R4 (following the sequence they were performed), FDM (mean of two readings on first day) and SDM (mean of two readings on second day) and SRM (R2-R4 means).

Sedentary lifestyle and its associated factors among adolescents from public and private schools of a Brazilian state capital.

Background: Adolescence is a transition stage between childhood and adulthood and is an important phase for the acquisition of future lifestyles, including the practice of physical activity (PA). The prevalence of sedentary lifestyle in adolescents is often high, creating the need for studies addressing the practice of PA and its associated factors for a better understanding of the phenomenon and possible interventions that would encourage positive changes.

Methods: Cross-sectional study of a representative sample of students aged 14-18 years enrolled in both public and private schools of a large Brazilian city to determine the level of physical activity (PA) and its associated factors.

Correlation of Insulin Resistance with Anthropometric Measures and Blood Pressure in Adolescents.

Background: Blood pressure is directly related to body mass index, and individuals with increased waist circumference have higher risk of developing hypertension, insulin resistance, and other metabolic changes, since adolescence.

Objective: to evaluate the correlation of blood pressure with insulin resistance, waist circumference and body mass index in adolescents.

Methods: Cross-section study on a representative sample of adolescent students.

Does nutritional status interfere with adolescents' body image perception?

Adolescents' body image (BI) may not match their nutritional status. This study selected representative sample of healthy adolescents aged between 12 and 18 from public and private schools. Anthropometric measures were performed in order to calculate the body mass index (BMI) percentile.
