The thickness of subcutaneous fat can be estimated from a number of parameters. This can be important when planning a subcutaneous injection so that the needle insertion is not too much (into skeletal muscle) or too little (into the dermis). The authors are from University Hospital Tuebingen and Ypsomed AG in Europe.
Outcome: thickness of subcutaneous adipose tissue (SCAT) in centimeters
Parameters:
(1) gender
(2) body mass index (BMI)
(3) anatomic site on the body
SCAT in scm =
= ((slope value for site and gender) * (BMI)) + (intercept for site and gender)
