Formulae & sources
BMI categories: WHO. Asian-Pacific cut-offs (overweight ≥23, obese ≥27.5) shown where relevant.Lean body weight: Boer P. Am J Physiol 1984 (men 0.407·wt + 0.267·ht − 19.2; women 0.252·wt + 0.473·ht − 48.3).
Ideal body weight: Devine BJ, 1974. Adjusted body weight = IBW + 0.4 × (actual − IBW).
Body surface area: Mosteller RD. N Engl J Med 1987 — √(ht·wt/3600).
Creatinine clearance: Cockcroft DW, Gault MH. Nephron 1976;16:31-41. Creatinine SI conversion: µmol/L ÷ 88.4 = mg/dL.
