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...

BACKGROUND Some studies have demonstrated the role of calcium in reducing body mass index (BMI) or fat mass. Though, BMI does not provide very valid information about changes in body fat mass, Fat Mass Index (FMI) relates body fat mass to height and allows comparing body fat mass of individuals at different heights. This study investigated the possible association between dietary calcium intake...

BACKGROUND Recent studies suggest that adjustment of measures of lean mass for adiposity improves associations with physical function. Our objective was to develop and test a method to adjust appendicular lean mass for adiposity. METHODS Whole-body DXA data in 14,850 adults in the National Health and Nutrition Examination Survey were used to generate sex-, and race-specific standard deviation...

Introdução: Os classificadores utilizados nos algoritmos da inteligência artificial precisam ser avaliados com métricas que sejam capazes de aferir a confiabilidade seus outputs. A maioria deles utiliza o número valores verdadeiros positivos e negativos, além dos falsos obtidos partir matriz confusão, seja ela uma ordem nxn qualquer. Um maiores desafios do machine learning é minimizar overfitti...

In many cases bioavailability and toxicity of cationic metals in soils is determined by the free metal ion (FMI) activity in soil solution. Recently methods were developed that relate biological effects to FMI activity. The use, validation and further development of such approaches require determination of FMI activities in soil. FMI activity determination is, however, prone to methodological a...

This study investigated whether the riboflavin analogs, 7,8-dimethyl-10-formylmethyl isoalloxazine (FMI) and 7,8-dimethyl-10-(2'-hydroxyethyl) isoalloxazine (HEI), are effective antihypertensive agents in mineralocorticoid-induced or deoxycorticosterone acetate (DOCA)-salt hypertension. These studies are based on our previous observation tht aldosterone enhances the biosynthesis of renal flavin...

BACKGROUND A low or high body mass index (BMI) has been associated with increased mortality risk in older subjects without taking fat mass index (FMI) and fat-free mass index (FFMI) into account. This information is essential because FMI is modulated through different healthcare strategies than is FFMI. OBJECTIVE We aimed to determine the relation between body composition and mortality in old...

CONTEXT Polymorphism at the insulin gene (INS) variable number of tandem repeat (VNTR) shows variable associations with childhood body mass index (BMI) in different populations. OBJECTIVE The objective of this study was to observe INS VNTR associations with body composition and insulin secretion in children. DESIGN The study was designed as a prospective birth cohort study. PARTICIPANTS A...
