Triceps skinfold thickness (TSF)

Definition

Triceps skinfold thickness (TSF) measures the subcutaneous fat layer at the triceps area to estimate body fat percentage. It is an important anthropometric parameter used to assess nutritional status and caloric reserves.

5 Must Know Facts For Your Next Test

1. TSF is measured using a skinfold caliper, typically at the midpoint of the upper arm.
2. It helps in assessing both undernutrition and overnutrition in clinical settings.
3. A high TSF value may indicate excess body fat, while a low value may suggest malnutrition.
4. TSF measurements are often used alongside other anthropometric assessments like BMI and mid-upper arm circumference (MUAC).
5. Accurate TSF measurement requires proper technique and training to ensure reliability.
