Nutrition Core: Nutrition Assessment Unit

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:

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)

Energy Expenditure

  • 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
  • Physical Activity
    • Acti-trac Accelerometers

Nutrition Core: Dietary Assessment Unit

The Dietary Assessment Unit of the Nutrition Core provides a broad range of nutrition-related research services to investigators at the Children's Hospital of Philadelphia, the Hospital of the University of Pennsylvania (HUP) and Penn Presbyterian Medical Center (PMC). Services include:

Protocol Consultation

We can develop methodologies for research protocols including:

  • Metabolic/controlled nutrient diet plans
  • Monitoring plans during a controlled diet
  • Food frequency questionnaires, food records, and nutrition data collection forms
  • Special meals designed by protocol parameters
  • Duplicate, weighed meals for nutrient balance studies

Close section

Protocol-Specific Nutrition Education

We can provide customized nutritional counselling interventions for inpatient and outpatient research protocols.

Close section

Training

  • Study Coordinator training for nutrition data collection
  • Family and study subject training on proper methods for weighing and measuring food items for food recalls/records

Close section

Calculated Research Meals for Controlled Studies

The metabolic kitchen can provide numerous services including:

  • Recipe development and modification
  • Food product design and production for study interventions
  • Calculation and serving of special research diets, including constant diets and regulated fluid intake

Close section

Nutrition Software for Meal and Diet Analysis

We provide access to Minnesota Nutrition Data System for Research (MNDS) and Food Processor (ESHA Research)
