Background: Body fat (BF) percentiles for German children and adolescents have recently been published. This study aims to evaluate the association between bioelectrical impedance analysis(BIA)-derived BF and cardiovascular risk factors and to investigate whether BF is better suited than BMI in children and adolescents. Methods: Data of 3,327 children and adolescents (BMI > 90th percentile) wer...

Background: The debate regarding use of WHO body mass index (BMI) cut-offs for the assessment of nutritional status continues in the scientific community. That is, BMI may not be a true reflection of body composition. Researchers have investigated BMI and percent body fat (%BF) as risk factors for some chronic diseases. Objectives: The current study sought to evaluate the use of BMI to assess %...

Overweight and obesity in Asian children are increasing at an alarming rate; therefore a better understanding of the relationship between BMI and percentage body fat (%BF) in this population is important. A total of 1039 children aged 8-10 years, encompassing a wide BMI range, were recruited from China, Lebanon, Malaysia, The Philippines and Thailand. Body composition was determined using the 2...

BACKGROUND Multiple screening tools, such as BMI and skinfold-derived percent body fat (%BF), are available to identify youth at risk of excess adiposity. However, poor classification agreement among these tools can be problematic for those interpreting test results. PURPOSE The purpose of this study was to investigate the validity of using BMI as an estimate of %BF in youth and to identify o...

BACKGROUND The body mass index (BMI) is based on the original concept that body weight increases as a function of height squared. As an indicator of obesity the modern BMI assumption postulates that adiposity also increases as a function of height in states of positive energy balance. OBJECTIVE To evaluate the BMI concept across different adiposity magnitudes, in both children and adults. M...

Background: The World Health Organization released lower Body Mass Index (BMI) cutoff points for Asian individuals to account for increased body fat percentage (BF%) and risk of obesity-related conditions at a lower body mass index. Purpose: This preliminary study: (1) explores the impact of utilizing Asian BMI standards (compared to universal standards) on the overweight/obese categorization o...

The objective of this study was to develop cut-off values and evaluate the accuracy of body mass index (BMI) in the definition of obesity in the Thai population. A cross-sectional, epidemiologic study in 340 men and 507 women aged 50 +/- 16 yr (mean +/- SD; range: 20-84 yr), were sampled by stratified clustering sampling method. Body composition, including percentage body fat (%BF), was measure...

OBJECTIVE The present study examined the associations between adult food insecurity (FI) and percentage body fat (%BF) and BMI, stratified by height (HT). DESIGN, SETTING AND SUBJECTS %BF, HT and BMI of 2117 men and 1909 women in the National Health and Nutrition Examination Survey 1999-2002 were analysed in relation to adult food security status using multiple regression procedures. RESULT...

OBJECTIVE Our aim was to examine the degree to which changes in BMI percentile reflect changes in body fat and lean body mass during childhood and how age and gender affect these relationships. METHODS This analysis used serial data on 494 white boys and girls who were aged 8 to 18 years and participating in the Fels Longitudinal Study (total 2319 observations). Total body fat (TBF), total bo...
