Description

I am analysing data from the Understanding society Nurse Health assessment. To evaluate kidney function I aim to use creatinine values from the blood samples and a measure of creatinine production (essentially muscle mass). The sunbjects underwent bioimpedance assessment of body composition and the nurse noted the body fat percentage which I find in the documentation and in the variables. Since the device used (Tanita scale) also present other measures like total body muscle mass, lean body mass, total body water and possibly body cell mass I am curious to know if these data also have been recorded?

Finding a better measure for muscle mass than subtracting fat mass from body weight to get lean body mass is essential for our study. The key concept of our current research is assessing kidney function without using the estimated GFR from creatinine to be able to adress some possible confounders of the association between estimated GFR and adverse outcomes.

I would much appreciate any guidance you can provide in this matter.

Yours sincerely,
