○ Current weight of 85 - 95% of usual body weight = mild malnutrition
○ 75 - 84% = moderate malnutrition
○ < 75% = severe malnutrition
● Recent weight change: ((usual weight - current weight) / usual weight) x 100
○ Clinically significant/abnormal:
■ Unintentional loss of > 5% of body weight over 1 month
■ > 7.5% over 3 months
■ > 10% over 6 months
● BMI: weight (kilograms) / height (meters)^2 OR (weight (pounds) / height (inches)^2) x
703
○ Interpretation for adults:
■ < 18.5 = underweight
■ 18.5 - 24.9 = normal weight
■ 25 - 29.9 = overweight
■ 30 - 39.9 = obesity
■ > 40 = extreme obesity
○ Interpretation for children ages 2 - 20 years old
■ < 5th percentile = underweight
■ 5th - 85th = healthy weight
■ 85th - 95th = overweight
■ > 95th = obese
● Obese people with a greater proportion of fat in the upper body have android obesity
● Obese people with most of their fat in the hips and thighs have gynoid obesity
● Waist to hip ratio: waist circumference (inches) / hip circumference (inches)
○ A waist to hip ratio of 1.0 or greater in men or 0.8 or greater in women
indicates android obesity and increases risk for obesity-related diseases and
early mortality
■ Android obesity - fat in visceral area where major organs are located
○ A waist circumference of > 35 inches in women and > 40 inches in men
increases risk for heart disease, type 2 diabetes, and metabolic syndrome
