BACKGROUND Estimates of body-composition change in older adults are mostly derived from cross-sectional data. OBJECTIVE We examined the natural longitudinal patterns of change in fat-free mass (FFM) and fat mass (FM) in older adults and explored the effect of physical activity, weight change, and age on these changes. DESIGN The body composition measured by hydrodensitometry and the level o...

INTRODUCTION Body composition (BC) assessments in heart failure (HF) patients are mainly based on body weight, body mass index and waist-to-hip ratio. The present study compares BC assessments by basic anthropometry, dual energy X-ray absorptiometry (DXA), bioelectrical impedance spectroscopy (BIS), and air displacement plethysmography (ADP) for the estimation of fat (FM) and fat-free mass (FFM...

BACKGROUND Overweight/obesity has been reported to worsen pulmonary function (PF). This study aimed to examine the association between PF and several body composition (BC) measures in two population-based cohorts. METHODS We performed a cross-sectional analysis of individuals aged 18 and 30 years from two Pelotas Birth Cohorts in southern Brazil. PF was assessed by spirometry. Body measures t...

The Five-factor model (FFM) provides a viable dimensional model of personality disorder assessment. Advantages of the FFM include the provision of a precise yet comprehensive description of both normal and abnormal personality functioning, the avoidance of the many limitations and problems inherent to the categorical diagnostic system, and the incorporation of basic science research on general ...

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 ...

Photolithographic methods allow an easy lateral top-down patterning and tuning of surface properties with photoreactive molecules and polymers. Employing friction force microscopy (FFM), we present here different FFM-based methods that enable the characterization of several photoreactive thin organic surface layers. First, three ex situ methods have been evaluated for the identification of irra...

Clinical utility, or the usefulness of a diagnostic system in clinical practice, has been identified as an important construct in proposed revisions to the diagnostic nomenclature and a significant limitation of dimensional models of personality disorder, such as the 5-factor model (FFM). Only 1 study to date has addressed explicitly the clinical utility of the FFM, and the findings suggested s...

INTRODUCTION Estimation of body composition as fat-free mass (FFM) is subjected to many variations caused by injury and stress conditions in the intensive care unit (ICU). Body cell mass (BCM), the metabolically active part of FFM, is reported to be more specifically correlated to changes in nutritional status. Bedside estimation of BCM could help to provide more valuable markers of nutritional...

BACKGROUND The objectives of this study were to develop a regression model for predicting fat-free mass (FFM) in a population of healthy Taiwanese individuals using standing foot-to-foot bioelectrical impedance analysis (BIA) and to test the model's performance in predicting FFM with different body fat percentages (BF%). METHODS We used dual-energy X-ray absorptiometry (DXA) to measure the FF...

BACKGROUND Clinical application of body composition (BC) measurements for individual children has been limited by lack of appropriate reference data. OBJECTIVES (1) To compare fat mass (FM) and fat free mass (FFM) standard deviation scores (SDS) generated using new body composition reference data and obtained using simple measurement methods in healthy children and patients with those obtaine...
