Eating attitudes and body image in ethnic Japanese and Caucasian adolescent girls in the city of São Paulo, Brazil.

Objective: Despite investigations into the rapid increase in eating disorders across diverse ethnic groups, conclusions concerning ethnicity and eating disorders are contradictory. The objective of the present study was to investigate eating attitudes in ethnic Japanese and Caucasian adolescents in Brazil. The influence of body mass index (BMI), menarche and social-affective relationships on the development of eating disorders was also assessed.

Anthropometry and body composition in ethnic Japanese and Caucasian adolescent boys.

Background: The effect of environmental conditions on development, including growth, maturation and the fulfillment of genetic potential, can be identified through the study of the variations found among different ethnic groups in the same population. The objectives of the present study were: (i) to compare the various anthropometric and body composition parameters based on ethnicity and maturation stage in 31 Japanese and 99 Caucasian prepubescent boys and 50 Japanese and 98 Caucasian post-pubescent boys; and (ii) to assess body mass index (BMI) and its relationship with other methods of body fat evaluation.

Methods: The percentage of body fat was measured using bioelectrical impedance, near-infrared interactance and Slaughter cutaneous skinfold equations.

[Anthropometric assessment of Kamayurá adolescents in the Upper Xingu, Central Brazil (2000-2001)].

Little is known about the nutritional status of indigenous adolescents. The present study aimed to evaluate the nutritional status of Kamayurá adolescents.
