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.
Validation of the Healthy Eating Index with use of plasma biomarkers in a clinical sample of women
Diet nutrition diet quality
2016/6/14
The Healthy Eating Index (HEI) is a 100-point
analytic scoring tool used to measure compliance with dietary
recommendations and guidelines.
Validation of a self-administered food-frequency questionnaire administered in the European Prospective Investigation into Cancer and Nutrition (EPIC) Study: comparison of energy, protein, and macronutrient intakes estimated with the doubly labeled water, urinary nitrogen, and repeated 24-h dietary recall methods
Validity biomarkers energy expenditure
2016/6/1
The validation of dietary assessment instruments is
critical in the evaluation of diet as a chronic disease risk factor.
Euglycemic hyperinsulinemic clamp to assess posthepatic glucose appearance after carbohydrate loading. 1. Validation in pigs
Glucose insulin intestinal absorption
2016/5/31
Precise knowledge of the rate of glucose absorption
after meal feeding requires invasive methods in humans.
Total body protein in healthy adolescent girls: validation of estimates derived from simpler measures with neutron activation analysis1,2,3
Body composition adolescents total body protein total body nitrogen fat-free mass neutron activation analysis
2008/12/9
Background: Little recent and accurate information about body protein content in healthy adolescent girls is available. Objective: The objective was to assess the total body nitrogen (TBN) and total b...
Validation study of energy expenditure and intake during calorie restriction using doubly labeled water and changes in body composition1,2,3
Doubly labeled water method DLW energy intake body composition metabolic chamber
2008/12/9
Background: Clinical trials involving calorie restriction (CR) require an assessment of adherence to a prescribed CR with the use of an objective measure of energy intake (EI).Objective: The objective...
Body fat measurement by bioelectrical impedance and air displacement plethysmography: a cross-validation study to design bioelectrical impedance equations in Mexican adults
bioelectrical impedance fat measurement
2008/4/23
The study of body composition in specific populations by techniques such as bio-impedance analysis (BIA) requires validation based on standard reference methods. The aim of this study was to develop a...
Validation of the MEDFICTS dietary questionnaire: A clinical tool to assess adherence to American Heart Association dietary fat intake guidelines
MEDFICTS dietary questionnaire Validation
2008/4/23
Dietary assessment tools are often too long, difficult to quantify, expensive to process, and largely used for research purposes. A rapid and accurate assessment of dietary fat intake is critically im...
Development and validation of skinfold-thickness prediction equations with a 4-compartment model
anthropometry adipose tissue nutritional assessment
2016/12/30
We developed new skinfold-thickness equations by using a 4-compartment model as the reference. Additionally, we compared our new equations with the Durnin and Womersley and Jackson and Pollock skinfol...
Validation of bioelectrical impedance analysis in patients with amyotrophic lateral sclerosis
Amyotrophic lateral sclerosis fat-free mass
2016/12/30
Amyotrophic lateral sclerosis (ALS) is a neurologic disease with an unfavorable prognosis that may be accompanied by malnutrition or overweight. Nutritional status is difficult to evaluate in these pa...
Validation of a soy food-frequency questionnaire and evaluation of correlates of plasma isoflavone concentrations in postmenopausal women
Soy isoflavones postmenopausal women
2016/12/29
Soy foods may have various health benefits, but little is known about the patterns and correlates of soy consumption among postmenopausal women in the United States.
Whole-body skeletal muscle mass: development and validation of total-body potassium prediction models
whole-body counting total body potassium skeletal muscle
2016/12/27
We explored 2 SM prediction approaches, one based on the assumption that the ratio of TBK to SM is stable in healthy adults and the other on a multiple regression TBK-SM prediction equation.
Bioelectrical impedance measurements in patients with gastrointestinal disease: validation of the spectrum approach and a comparison of different methods for screening for nutritional depletion
Patients gastrointestinal disease depletion
2017/1/4
BIS measures of body fluids are influenced by the presence of depletion, probably because of alterations in the electric properties of the body at the cellular level. However, for screening purposes, ...
Indicators of marginal biotin deficiency and repletion in humans:validation of 3-hydroxyisovaleric acid excretion and a leucine challenge
