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...
Calibration and validation of an air-displacement plethysmography method for estimating percentage body fat in an elderly population: a comparison among compartmental models
Body composition elderly men
2016/6/14
The use of hydrostatic weighing (HW) to measure
body composition in the elderly can be difficult and is based on
the assumption of constancy of body compartments.
A novel extrinsic reference method for assessing the vitamin A value of plant foods
carotenoid bioavailability vitamin A retinol equivalency
2016/6/14
The amounts of vitamin A that are metabolically
derived from specific carotene-containing foods are largely
unknown.
Use of the leg-to-leg bioelectrical impedance method in assessing body-composition change in obese women
obesity fat-free mass percentage body fat
2016/5/30
There is little information on whether bioelectrical
impedance analysis (BIA) accurately predicts changes in body
composition associated with energy restriction, exercise, or both.
Comparison of indirect calorimetry, the Fick method, and prediction equations in estimating the energy requirements of critically ill patients
Energy expenditure critical illness indirect calorimetry
2016/5/30
Accurate measurement of resting energy expenditure
(REE) is helpful in determining the energy needs of critically
ill patients requiring nutritional support. Currently, the
most accurate clinical t...
Assessment of total body stores of vitamin A in Guatemalan elderly by the deuterated-retinol-dilution method

2016/5/30
Deuterated retinol dilution (DRD) gives
quantitative estimates of total body stores of vitamin A.
Infant feeding method and obesity: body mass index and dual-energy X-ray absorptiometry measurements at 9–10 y of age from the Avon Longitudinal Study of Parents and Children (ALSPAC)1,2,3
Avon Longitudinal Study of Parents and Children ALSPAC epidemiology
2008/12/11
Background: Previous studies reported inconsistent associations between breastfeeding and body mass index (BMI; in kg/m2). Associations with body fatness are unknown.Objective: We investigated the ass...
Associations between diet and disease activity in ulcerative colitis patients using a novel method of data analysis
disease activity diet Associations
2008/4/23
The relapsing nature and varying geographical prevalence of ulcerative colitis (UC) implicates environmental factors such as diet in its aetiology.
Daily calcium intake in male children and adolescents obtained from the rapid assessment method and the 24-hour recall method
rapid assessment method adolescents obtained
2008/4/23
In order to rapidly assess nutrient intake, Food Frequency Questionnaires (FFQ) have been developed and proven to be reliable for quick, user friendly analysis in adults. However, the accuracy of thes...
Trichotillometry: the reliability and practicality of hair pluckability as a method of nutritional assessment
practicality reliability Trichotillometry
2008/4/23
Background
A nutritional assessment method that is quick and easy to conduct would be extremely useful in a complex emergency, where currently there is no agreed practical and acceptable method. Hair...

Food intake energy intake obesity
2016/12/30
This observational validation study was conducted under controlled conditions to test the effectiveness of the US Department of Agriculture (USDA) 5-step multiple-pass method for dietary recall; to te...
Vitamin A equivalence of spirulina β-carotene in Chinese adults as assessed by using a stable-isotope reference method
Vitamin A β-carotene
2016/12/30
In a group of well-nourished, normal-weight Chinese men following low-vitamin A diets, 4.5 mg spirulina β-carotene consumed with 22 g fat has the same vitamin A activity as does 1 mg retinyl acetate.
