OBJECTIVE We sought to assess whether cultural ideals of the male body, as illustrated by magazine models, have changed over the past 25 years. METHOD We examined 115 male centerfold models in Playgirl magazine from 1973 to 1997. Using the models' heights and weights quoted by the magazine, together with visual estimates of body fat, we calculated the body mass index (BMI) and fat-free mass i...

The objective of the present study was to determine the association between CT phenotypes-emphysema by low attenuation area and bronchitis by airway wall thickness-and body composition parameters in a large cohort of subjects with and without COPD. In 452 COPD subjects and 459 subjects without COPD, CT scans were performed to determine emphysema (%LAA), airway wall thickness (AWT-Pi10), and lun...

INTRODUCTION Studies of obesity require the estimation of fat mass (FM) and fat-free mass (FFM); therefore it is important to validate methods that evaluate these measurements. OBJECTIVE We sought to compare two different bioelectrical impedance analysis systems (BIAs) to estimate FM and FFM using dual-energy X-ray absorptiometry (DXA) as reference. METHODS We used a cross-sectional design....

OBJECTIVE To assess the levels of adiposity and physical activity among Saudi preschool children from Jeddah. METHODS Participants included 224 Saudi preschool children, randomly selected from public and private preschools in Jeddah during April and May of 2006, using a multistage stratified sampling technique. Measurements included weight, height, body mass index, triceps and subscapular ski...

Background: The first years of life are critical for human development, therefore it is important to investigate early factors that may influence the development of body composition later in life. In this study, we aimed to evaluate the association between breastfeeding duration and age of introduction of complementary feeding with body composition at 18–19 years. Methods: This is a prospective...

BACKGROUND Higher meat and protein intakes have been associated with increased body weight in adults, but studies evaluating body composition are scarce. Furthermore, our knowledge in adolescents is limited. This study aimed to investigate the prospective associations of intakes of different meat types, and their respective protein contents during childhood, with body composition during adolesc...

Early excessive weight gain is positively associated with later obesity, and yet the effect of weight gain during specific periods and the impact of infant feeding practices are debated. The objective of the present study was to examine the impact of weight gain in periods of early childhood on body composition at 3 years, and whether infant feeding modified the relationship between early growt...

OBJECTIVE The study examined the validity of simple and novel measures of generalized obesity- [body mass index (BMI, kg/m2), fat mass index (FMI, kg/m2), and body fat percent (BF%)] and central obesity--[waist circumference (WC, cm), waist-hip ratio (WHR), and waist-to-height ratio (WC/ht ratio)] against BF% and BMI as criteria. It also aimed to predict fat-free mass index (FFMI, kg/m 2 ), FMI...

Introduction. Calculations of the components body mass: fat, muscle and bone serve as an objective characteristic a person's physique. The aim: to evaluate composition indicators patients with COPD establish correlational relationships. Materials methods. 120 were examined, evenly distributed by degree severity (GOLD 1-4). Average age (56.67 ± 10.28) years. We determined: mass index (BMI), BMD ...

BACKGROUND Weight loss and depletion of fat-free mass are common problems in patients with chronic obstructive pulmonary disease (COPD) and are related to muscular weakness and exercise intolerance. Physical training of COPD patients has good effect on exercise tolerance and quality of life. The aim of this study was to examine factors that affect change in fat-free mass after physical training...
