Obesity and salt intake are both established factors contributing to cardiovascular
disease development. Recently, studies found a controversial positive relationship
between dietary salt and obesity. Therefore, the authors investigated whether obesity‐
related measures are associated with 24‐hour urinary sodium in a healthy biethnic
population. The study included 761 adults (20‐30 years) with complete 24‐hour
urinary sodium, anthropometry, and bioelectrical impedance measurements. In single
regression analyses all obesity‐related measures related positively with 24‐hour
urinary sodium (P ≤ .008). However, with multivariate adjustments for energy intake,
accelerometery, age, sex, black and white ethnicity, and other covariates, only body
surface area (BSA) remained independently associated with 24‐hour urinary sodium
(R2 = 0.72, β = .05, P = .039). To conclude, we found a consistent and robust positive
relationship between BSA and estimated salt intake – but not with traditional obesity
measures such as body mass index (BMI). Further studies are needed to investigate
body surface area and potentially, skin area, in salt handling
