Previous research has shown that experiencing childhood famine is linked to various chronic conditions like diabetes, hypertension, and proteinuria.

The eGFR in the exposed groups was significantly lower compared to the nonexposed group. Specifically, famine exposure correlated with a lower eGFR (coefficient estimates [CE] −9.14, 95% confidence interval [CI] −9.46, −8.82), with the strongest association observed in the adolescence/adult-exposed group (CE −26.74, 95% CI −27.75, −25.74).

Since body weight does not reflect body composition, other methods are needed to determine muscle mass, often estimated by fat-free mass (FFM). Bioimpedance spectroscopy (BIS) is frequently used for monitoring body composition in patients with kidney failure. Unfortunately, BIS-derived lean tissue mass (LTM_BIS) is not suitable for comparison with FFM cutoff values for the diagnosis of malnutrition, or for calculating dietary protein requirements. Hypothetically, FFM could be derived from BIS (FFM_BIS). This study aims to compare FFM_BIS and LTM_BIS with computed tomography (CT) derived FFM (FFM_CT).
