What can be used instead of skinfold measurements for someone with a BMI greater than 30?

Girth measurements are a practical alternative for assessing body composition, especially in individuals with a BMI greater than 30. Skinfold measurements, which involve pinching skin at certain sites to assess subcutaneous fat, can be challenging and potentially less accurate in individuals with higher levels of body fat. Girth measurements involve measuring the circumference of various body parts, such as the waist, hips, and limbs, which can provide valuable information about body composition and fat distribution without the need for skinfold calipers.

This method can be easier to perform than skinfold measurements and can be more appropriate for individuals who may be uncomfortable with or unable to undergo more invasive techniques. Girth measurements can effectively track changes over time, making them useful for monitoring progress in exercise and weight management programs.

Body mass index (BMI), while helpful for screening purposes, does not distinguish between fat and lean mass. Underwater weighing requires specialized equipment and is less feasible in many clinical settings. Bioelectrical impedance can provide information about body composition but may be influenced by hydration status and may not be as reliable in individuals who have a higher body fat percentage. Therefore, girth measurements stand out as an accessible and effective method for assessing body composition in this population.
