A 38-year-old female is 5 ft 8 in (68 in) and weighs 170 lb. Her waist circumference is 36 inches. Using the BMI formula with imperial units (BMI = 703 × weight in lb / height in in^2) and waist threshold, calculate her BMI to one decimal and assess whether her waist indicates elevated central obesity risk.

• A. BMI = 22.4 kg/m^2 (Healthy), and waist 36 in is below female threshold so no elevated risk
• B. BMI = 25.9 kg/m^2 (Overweight); waist 36 in indicates elevated central obesity risk for a woman
• C. BMI = 30.2 kg/m^2 (Obese) and waist 36 in indicates low visceral fat because waist circumference must exceed 40 in to be meaningful
• D. BMI cannot be calculated with imperial units; only waist matters clinically, so this is indeterminate

Answer: (B)
