INTRODUCTION In this study we determined regional body composition in myotonic dystrophy (DM1) and able-bodied controls and evaluated the relationship between fat and lean tissue mass and functional impairment in DM1 patients. METHODS Dual-energy X-ray absorptiometry (DEXA) was used to obtain regional measurements of fat-free mass index (FFMI) and fat mass index (FMI) in 48 DM1 and anthropome...

purpose the purpose of this investigation was to compare a practical measurement of fat free mass index (ffmi) from bioelectrical impedance analysis (bia) to the dual energy x-ray absorptiometry (dexa) value in collegiate athletes. methods thirty-three male baseball players and 16 female gymnasts volunteered to participate in this study during their respective pre-season. subjects visited the l...

INTRODUCTION Age related muscle loss, termed sarcopenia, has been linked to an increased risk of falls, disability, and mortality [1]. Researchers have used normalized fat free mass (FFMI) measurements, compared to a reference population to successfully identify older adult with sarcopenia [2]. The purpose of this study was to develop a predictive measurement tool to accurately estimate normali...

OBJECTIVE Postnatal tissue accretion in preterm infants differs from those in utero, affecting body composition (BC) and lifelong morbidity. Length normalized BC data allows infants with different body lengths to be compared and followed longitudinally. This study aims to analyze BC of preterm and term infants during the first six months of life. METHODS The BC data, measured using dual energ...

Background—Sex specific cross sectional reference values for lung function indices usually employ a linear model with terms for age and stature. The eVects of also matching for body mass index (BMI = mass/stature) or its components, fat percentage of body mass (fat%) and fat free mass index (FFMI = fat free mass/ stature) were studied. Methods—The subjects were 458 asymptomatic male and female ...

BACKGROUND Increased rates of overweight/obesity have been reported in recent years in developed countries. This population study of healthy subjects evaluated the changes in overweight/obesity prevalence in 2003, compared with 1993, and determined the association of age, sex and leisure-time activity with body mass index (BMI), fat-free mass index (FFMI) and fat mass index (FMI). DESIGN Two ...

The effects of tobacco smoke, mild/moderate COPD disease and their combined effect on health status (HS), body composition (BC), and exercise capacity (EC) impairment are still unclear. We hypothesized that smoking and early COPD have a joint negative influence on these outcomes. We evaluated 32 smokers (smoking history >10 pack/years), 32 mild/moderate COPD (current smokers or former smokers),...

This study aimed to classify the body composition of puberty students into six categories, using Fat Mass Index (FMI) and Free (FFMI), identify characteristics their physical fitness motor capacity in each category. FMI FFMI are (FM; Mass, FFM; Mass) divided by height squared. The participants were 1,482 high school (815 males 667 females) aged 15-17 years old. measurements height, weight, FFM ...

Microalbuminuria is considered as a marker of endothelial dysfunction and found to be associated with nephropathy and cardiomyopathy in diabetic and nondiabetic obese patients. In this study, we sought to investigate the effect of childhood obesity on microalbuminuria in children. A total of 96 children who were clinically healthy were enrolled from July 2007 through March 2012. Height, weight ...

The objective of the present study was to investigate the relationship between the indices of body size such as BMI, fat-free mass index (FFMI, FFM/height2), fat mass index (FMI, FM/height2), and body fat percentage (%BF), and physical activities assessed by the doubly-labelled water (DLW) method and an accelerometer in free-living Japanese adult women. We conducted a cross-sectional study in 1...
