Anthropometric Indicators as Body Fat Discriminators in Children and Adolescents: A Systematic Review and Meta-Analysis.

We analyzed the discriminatory capacity of anthropometric indicators for body fat in children and adolescents. This systematic review and meta-analysis included cross-sectional and clinical studies comprising children and adolescents aged 2-19 y that tested the discriminatory value for body fat measured by anthropometric methods or indexes generated by anthropometric variables compared with precision methods in the diagnosis of body fat [dual-energy X-ray absorptiometry (DXA), computed tomography, air displacement plethysmography (ADP), or MRI]. Five studies met the eligibility criteria and presented high methodologic quality.

What Physical Fitness Component Is Most Closely Associated With Adolescents' Blood Pressure?

This study aimed to determine which of four selected physical fitness variables, would be most associated with blood pressure changes (systolic and diastolic) in a large sample of adolescents. This was a descriptive and cross-sectional, epidemiological study of 1,117 adolescents aged 14-19 years from southern Brazil. Systolic and diastolic blood pressure were measured by a digital pressure device, and the selected physical fitness variables were body composition (body mass index), flexibility (sit-and-reach test), muscle strength/resistance (manual dynamometer), and aerobic fitness (Modified Canadian Aerobic Fitness Test).

BODY IMAGE AMONG MEN WHO PRACTICE BODY BUILDING: COMPARISON BY AGE, ECONOMIC STATUS, AND CITY SIZE.

Identifying the factors that influence the body image of body builders is important for understanding this construct. The aim of this study was to analyze the association between body image and age, socioeconomic status, and place of residence of body builders from two cities in Brazil. A cross-sectional study of 301 body builders with an average age of 25.

Brazilian adolescents' body weight misperception and the Human Development Index of the cities where they live.

This study investigated the relationship between adolescents' body weight misperception and the Human Development Index (HDI) of the cities in which they live in Brazil. Data from a large national survey that included 60,973 boys and girls between 13 and 15 yr. (M = 14.
