Study Notes
BMI
- Cost-effective and requires no specialized equipment
- Non-invasive, making it easy to assess large populations
- Limitations: does not account for fat percentage or fat-free mass, making it less useful for evaluating athletic individuals
### Waist-to-Hip Ratio
- Very inexpensive and easy to measure
- Potential for high error in prediction equations
Skinfolds
- Low cost and easy to use
- Time-efficient but slightly invasive
- Requires specific skills to perform accurate measurements
### Hydrostatic Weighing (underwater weighing)
- Highly accurate technique
- Time-consuming and requires access to a pool or water tank
- Requires specific skills to utilize properly
Air Displacement (BodPod)
- User-friendly and time-efficient
- Highly accurate but expensive
Bioelectrical Impedance Analysis (BIA)
- Relatively low cost and easy to use, including self-administration
- Time-efficient
- Sensitivity to hydration levels introduces a high degree of error: dehydration can overestimate fat mass, hydration guidelines are recommended before testing
Dual-energy X-ray Absorptiometry (DEXA)
- Extremely accurate and non-invasive
- Provides a measurement of bone density
- Very expensive and may require trained personnel for operation
Clinical Assessment of Nutritional Status
- Clinical assessment plays a vital role in understanding a patient's nutritional status.
- It involves a multifaceted approach combining patient history, physical examination, and interpreting signs and symptoms.
- General Appearance: Assess for signs of malnutrition such as cachexia (severe wasting) or edema (fluid retention).
- Body Weight & Height: Measure and track changes to identify weight loss or gain and calculate Body Mass Index (BMI) for an overall assessment.
- Skin Assessment: Look for tenting (slow return of skin after pinching), which might indicate dehydration, and pigmentation changes, which could suggest vitamin deficiencies.
- Hair & Nails: Assess for brittleness, dryness, or changes in hair texture and nail growth, which might indicate nutritional deficiencies.
- Muscle Mass: Evaluate muscle wasting, which can be a sign of protein-energy malnutrition.
- Vital Signs: Monitor blood pressure and heart rate, as deviations from normal could indicate underlying nutritional issues.
