OBJECTIVE Our aim was to examine the degree to which changes in BMI percentile reflect changes in body fat and lean body mass during childhood and how age and gender affect these relationships. METHODS This analysis used serial data on 494 white boys and girls who were aged 8 to 18 years and participating in the Fels Longitudinal Study (total 2319 observations). Total body fat (TBF), total bo...

The design goal for the Fermilab Main Injector (FMI) is to accelerate a minimum of 6 10 protons per bunch through the transition. We present here the results from simulation studies of the transition crossing in the FMI using the particle tracking code ESME[1].

The general aim of early intervention and home visiting programs is to support families to minimize Adverse Childhood Experiences (ACEs). However, assessing children's exposure to these risks is complicated because parents serve as the conduit for both measurement and intervention. The primary aims of the study were to develop an assessment of children's exposure to ACEs and to examine concurre...

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...
