  1. Resource Description
    The Nutrition Assessment Unit of the Nutrition Core is a state-of-the-art facility for the assessment of growth and body dimensions, body composition (the amount of muscle, fat and bone in the body), energy expenditure, bone density, and muscle strength. The Unit has two locations and four experienced technicians for performing research assessments. Services provided by the Nutrition Assessment Unit include: 1) Anthropometric Measurements -- Basic Measurements (Height/length/weight/head circumference) -- Knee Height Assessment for Short Term Growth -- Circumferences (Arm/waist/hip/chest/calf) -- Skin Fold Thicknesses (Biceps/triceps/subscapular/supra iliac) -- Alternate Height Assessments (Lower leg length/upper arm length) -- Breadth Measures (Elbow, Shoulder, Abdominal depth) 2) Energy Expenditure a) Indirect Calorimetry -- Resting Energy Expenditure (REE, fasting with inpatient admission to CHPS) -- Sleep Energy Expenditure (SEE) (Fasting non-AM study) -- Respiratory Quotient (RQ) (Fasting) -- Post-Prandial Resting Energy Expenditure b) Physical Activity -- Acti-trac Accelerometers 3) Body Composition -- Infant Total Body Electrical Conductivity (TOBEC) -- Pea Pod (Infant Body Composition by Air-Displacement Plethysmography) -- Bioelectrical Impedance Analysis (BIA) -- Anthropometry -- Whole Body Dual Energy X-ray Abosrptiometry (DXA) -- Cross-sectional muscle area and fat area by peripheral Quantitative Computed Tomography (pQCT) 4) Bone Health Assessment a) Dual Energy X-Ray Absorptiometry (DXA) - For Infants, Children and Adults -- Whole Body Bone Density and Body Composition -- AP Lumbar Spine -- Lateral Lumbar Spine -- Hip -- Forearm -- Distal Femur -- Intervertebal Assessment b) Peripheral Quantitative Computed Tomography (pQCT) -- Cortical and trabecular bone density, cortical thickness and strain-strength index by measurement of -- Distal tibia -- Distal radius c) Ultrasound (CUBA) -- Calcaneus (children of 7 years of age and adults) 5) Muscle Strength Testing -- Biodex (isometric strength) -- Force Plate (jump strength) 6) Other Growth and Nutrition Assessment Measures -- Urine Pregnancy Testing prior to DXA Scan(s) -- Stable Isotope Dosing and Urine Collection Instruction -- Parent Education (Food records/stool and/or urine collections) -- Pubertal Assessment Form
