Study Notes
Body Composition and Fat Distribution
- Skinfold measurements: A method for estimating body fat percentage using calipers to measure the thickness of subcutaneous fat at specific sites.
-
Circumference Measurements : Used to assess body composition and fat distribution.
-
Waist Circumference: A practical indicator of central obesity, with high risk to health problems.
- Men: Above 40 inches (102 cm)
- Women: Above 35 inches (88 cm)
-
Waist Circumference: A practical indicator of central obesity, with high risk to health problems.
-
Waist-to-hip ratio: Dividing waist measurement by hip measurement.
- Apple Body Type: Ratio is close to or exceeds 1.0.
- Pear Body Type: Ratio is below 0.8.
Nutritional Assessment
- A comprehensive analysis of a person's nutritional status.
-
Methods of Nutritional Assessment:
- Historical Information:
- Anthropometric Data: Measurements of body size and composition, including height, weight, and body mass index (BMI).
- Physical Examinations: Assessing for signs of malnutrition or nutrient deficiencies.
- Laboratory Tests: Analyzing blood or urine samples to measure nutrient levels and identify potential deficiencies.
Laboratory Tests
- Used to uncover early signs of malnutrition before symptoms appear.
-
Blood Analysis: Determines actual nutrient levels in relation to expected level.
- Examples: Vitamin B12 and folate in white blood cells.
-
Urine Samples: Monitor baseline excretion of water-soluble nutrients.
- Metabolites of Nutrients: Levels can be monitored in urine.
- 24-Hour Urine Collection: Assessed for creatinine levels to indicate muscle turnover rates or nitrogen levels to check protein intake.
- Laboratory Values: Only a part of the complete assessment data.
Understanding Nutritional Assessment
- Provides a holistic view of a person's nutritional status.
- Helps identify potential risks and deficiencies.
- Guides personalized nutrition interventions and recommendations.
