What is the BMI of an adult, approximately 5 feet 7 inches (height) and 92.5 kilograms (weight)?

BMI Calculation

For an adult with height 5'7" (170 cm) and weight 92.5 kg, the BMI is 32.0 kg/m², which classifies as Class I Obesity.

Calculation Method

• BMI is calculated as weight in kilograms divided by height in meters squared: BMI = weight (kg) / [height (m)]² 1

• Converting 5'7" to metric: 5 feet 7 inches = 67 inches = 170.18 cm = 1.7018 meters 1

• Calculation: 92.5 kg / (1.7018)² = 92.5 / 2.896 = 32.0 kg/m² 1

BMI Classification

• A BMI of 32.0 kg/m² falls into Class I Obesity (BMI 30.0-34.9 kg/m²) according to World Health Organization criteria 2

• The standard BMI categories are:

  • Normal weight: BMI 18.5-24.9 kg/m² 1
  • Overweight: BMI 25.0-29.9 kg/m² 2
  • Class I Obesity: BMI 30.0-34.9 kg/m² 2, 1
  • Class II Obesity: BMI 35.0-39.9 kg/m² 2, 1
  • Class III Obesity: BMI ≥40 kg/m² 2, 1

Health Risk Implications

• Class I obesity (BMI 30-34.9) is associated with "high" disease risk for type 2 diabetes, hypertension, and cardiovascular disease 2

• This BMI level is associated with elevated risk of fatal cardiovascular disease compared to normal weight individuals 2

• Even modest weight loss of 3-7% of body weight (approximately 2.8-6.5 kg for this individual) can improve glycemia, blood pressure, and lipid profiles 2

Additional Assessment Recommendations

• Waist circumference should be measured alongside BMI for complete risk stratification 2, 1

• For men, waist circumference >102 cm (>40 inches) indicates increased cardiovascular risk; for women, >88 cm (>35 inches) indicates increased risk 2, 1

• BMI alone does not directly measure body fat distribution or account for individual differences in body composition 2
