Total-body skeletal muscle mass:estimation by a new dual-energy X-ray absorptiometry method
Body composition nutritional assessment skeletal muscle mass magnetic resonance imaging dual-energy X-ray absorptiometry
2016/12/19
Background: Skeletal muscle (SM) is an important body-composition component that remains difficult and impractical to quantify by most investigators outside of specialized research centers. A lar...
[13C]Linoleic acid oxidation and transfer into milk in stunted lactating women with contrasting body mass indexes
milk fat isotope ratio mass spectrometry body mass index
2016/6/14
The fat concentration of human milk is associated
with maternal adiposity, but there is no clear understanding of
the mechanisms controlling milk fat concentration.
Effect of highly active antiretroviral therapy on fat, lean, and bone mass in HIV-seropositive men and women
lipodystrophy fat redistribution lean body mass
2016/6/14
Alterations in body composition have been
reported in HIV-positive adults receiving highly active antiretroviral
therapy (HAART), but the magnitude and potential determinants
of these changes are u...
Family social class, maternal body mass index, childhood body mass index, and age at menarche as predictors of adult obesity
Body mass index BMI obesity
2016/6/14
Obesity is an increasingly prevalent nutritional
disorder throughout the world and is a risk factor for many
chronic diseases. The prevalence of obesity increases with age.
Prevalence of overweight in US children: comparison of US growth charts from the Centers for Disease Control and Prevention with other reference values for body mass index
Adolescents body weight body mass index
2016/6/13
Several different sets of reference body mass index
(BMI) values are available to define overweight in children.
Age-related decrease in resting energy expenditure in sedentary white women: effects of regional differences in lean and fat mass
fat mass lean mass resting energy expenditure
2016/6/12
Lean mass and resting energy expenditure (REE)
decrease with age. However, it is unknown whether age-related
changes in regional lean and fat mass are responsible for the agerelated
decrease in REE...
Receiver operating characteristic analysis of body mass index, triceps skinfold thickness, and arm girth for obesity screening in children and adolescents
ROC curve dual-energy X-ray absorptiometry DXA
2016/6/2
Valid and practical methods based on healthrelated
criteria for obesity screening in children and adolescents
are not available. Arbitrarily defined body mass index (BMI) cutoffs
have been proposed...
Longitudinal changes in adult fat-free mass: influence of body weight
Aging, body composition fat-free mass body fat
2016/6/2
Almost all of the data on changes in body composition
during aging are cross-sectional in nature. These show that
fat-free mass (FFM) declines with age.
Determination of skeletal muscle and fat-free mass by nuclear and dual-energy X-ray absorptiometry methods in men and women aged 51–84 y
bioimpedance analysis aging anthropometry
2016/6/1
Skeletal muscle mass (SMM) and fat-free mass
(FFM) are important variables in nutritional studies. Accurate
techniques for measuring these variables have not been thoroughly
validated in elderly su...
Tracking of body mass index in children in relation to overweight in adulthood
Childhood BMI adulthood overweight tracking
2016/5/31
Body mass index (BMI; in kg/m2
) values at or
above the 75th percentile are associated with increased morbidity
and mortality in adulthood, and there are significant correlations
between BMI value...
Fatness and body mass index from birth to young adulthood in a rural Guatemalan population
Body mass index fatness overweight
2016/5/31
Body mass index (BMI; wt in kg/ht2 in m) has
been proposed as a simple and valid measure for monitoring fatness.
Using data from a 25-y longitudinal study of rural Guatemalans, we
found that, as ch...
Validity of the body mass index as an indicator of the risk and presence of overweight in adolescents
Risk factors body composition overweight
2016/5/31
The validity of the body mass index (BMI) as
an indicator of the risk of becoming overweight and of the
presence of overweight was evaluated in 6 groups of adolescents
comprising several ethnic gro...
Introduction:the use of body mass index to assess obesity in children
BMI body mass index obesity
2016/5/31
The International Obesity Task Force (IOTF) was established in 1994 to address the increase in the worldwide prevalence of obesity. The goals of the IOTF are to 1) raise awareness in the population an...
Physical activity, protein intake, and appendicular skeletal muscle mass in older men
Aging sarcopenia uniaxial accelerometer
2016/5/31
Aging is associated with physical inactivity, low
energy intake, and loss of skeletal muscle mass. It is not clear
whether regular physical activity and adequate dietary protein
intake can attenuat...
Four-component model of body composition in children: density and hydration of fat-free mass and comparison with simpler models
Body fat dual-energy X-ray absorptiometry total body water
2016/5/31
Body composition in children is generally measured
by 2-component (2C) models, which are subject to error
arising from variation in fat-free mass (FFM) composition. The
4-component (4C) model, whic...
