Body mass index (BMI) is the most commonly used measure of obesity. Recently, some investigators have advocated direct measurement of adiposity rather than use of the BMI. This study was undertaken to determine the ability of BMI to predict body fat levels in three populations of West African heritage living in different environments. A total of 1,054 black men and women were examined in Nigeri...

BACKGROUND Because serum concentrations of leptin, a hormone produced by adipocytes, can be relatively reliably and inexpensively measured, it may be considered complementary to, or even a substitute for, body mass index (BMI) as a measure of adiposity. OBJECTIVE We examined the ability of BMI and leptin concentrations, separately and together, to estimate total percentage fat in older adults...

BACKGROUND South Asians were reported to have a higher liver fat content as compared to BMI-matched Caucasians. This study compared the increase in liver fat content in response to overfeeding with a high fat diet in South Asian and Caucasian men when matched for body fat percentage. METHODS Ten South Asian men (BMI 18-29 kg/m(2)) and 10 Caucasian men (BMI 22-33 kg/m(2)), aged 20-40 y, matche...

This descriptive correlational study aimed to analyze self-care behaviors and their relationship with health indicators represented by glycemic control, lipid profile, Body Mass Index [BMI], waist circumference and body fat percentage in a sample of 98 adults with type 2 diabetes in an area of Nuevo Leon, Mexico (August 2005/May 2006). The results showed a low self-care behaviors index (X = 36....

PURPOSE Obesity is a major public health issue and is associated with many metabolic abnormalities. Consequently, the assessment of obesity is very important. A new measurement, the body adiposity index (BAI), has recently been proposed to provide valid estimates of body fat percentages. The objective of this study was to compare the BAI and body mass index (BMI) as measurements of body adiposi...

PURPOSE Because of the potential protective function of lutein (L) and zeaxanthin (Z) within the retina and lens, a better understanding of factors influencing tissue deposition is needed. The largest fractions of L and Z are stored in adipose tissue. Thus, higher body fat content and body mass index (BMI) may be expected to influence the quantities of L and Z in the retina (measured as macular...

Background and Objectives: Although a growing interest on the role of self-efficacy in weight management is reported worldwide, less research has been carried out on this association in adolescents. The aim of the present study was to investigate association of weight linked self-efficacy with anthropometric measurements in Tehrani male adolescents. Materials and Methods: The study was carried...

Introduction: Complications of obesity and high fat in children are grave now and future. The aim of this research is comparing percentage of body fat in active and inactive girls using Anthropometric Parameters.Materials and Methods: This research is descriptive- correlation that 144 active(n= 70) and inactive(n= 74) girls aged 8 to 10 years old were selected by random cluster sampling method ...

Immunoreactive serum leptin was analysed in 49 women with polycystic ovary syndrome (PCOS) distributed on a wide range of body mass index (BMI; kg/m2) and in 32 normally menstruating women with comparable age, BMI, physical activity and dietary habits. All women with PCOS had increased androgen concentrations and obese women with PCOS (BMI > or = 25, n=24) also showed decreased insulin sensitiv...
